Abstract
Proposed is a value-bearing document in which the carrier is provided with a window-like opening which is closed by a cover foil which is transparent at least in a region-wise manner, wherein in particular in the region of the window-like opening the cover foil can be provided with additional security features, for example diffraction structures.
Description
2~3~2~
Value-bearing document with window The invention concPrns value-bearing documents, in parti~llar value-bearing papers, such as for example banknotes, cheques, travellers' cheques or share certificates, but also documents which do not consist of paper or which only partially consist of paper, for example credit cards, identity cards etc.
Parti~-lArly having regard to the options afforded by modern color copiers and other L~Lu~ucing systems, there is an urgent need for value-bearing documents to be provided with special security elements which make it difficult to produce a forgery using items of e~lirmPnt of that kind. A l OE ge nu~ber of possible procedures have already been proposed for that purpose.
It is known for ex~il~le for value-bearing documents such as value-bearing papers, c OEds, identity cards etc to be provided with security elements in the form of reflecting surfaces. Those reflecting surfaces OE e normally reproduced by a color copier as black surfaces. In this case however there is the possibility of subsequently applying a suitable, me~al 1 ;CA1 ly shiny layer.
A further improvement in affording a safeguard against forgery is achieved when security elements in the form of structures which have an optical-diffraction or optical-refraction effect, so-called diffraction structures, for example holograms, so-called pixelgrams etc OEe used.
However those security elements æe cull~aLa~ively Pxp~ive in tenms of production.
It is also already known for security elements for value-be OE ing documents to be so designed that they æ e suitable in partiClllAr for viewing in a transilll~;nation mode. For Px~"L)le AU-patent specificAtion No 488 652 describes security ~o~nts which comprise a plurality of interconnected plastic webs, wherein at least one optically variable security element is arranged between those webs and a I ~ ~aLenL window is provided in at least one of the cover webs in the region of the security element so that the security element can be viewed through the window. For applying the security elements, in accordance with the state of the art for P~AT~le the lJ ~ lre is such that an openinq is pro~ P~
in a plastic web which is disposed in the int OE ior of the ~oK~nPnt~ the security element being fitted into the opening. The security element is then fixed in the opening by cover foil~ which are Apr~ at both sides. A ~L~ced~re of that kind suffers on the one hand fron the disadvantage that the operation of applying the security element gives rise to major difficulties and in p æ ~ lAr the ~Loced~re requires lamination over the full surface areas of cu"~aLaLively l æ ge regions of plastic foils. Tncll~;on of the security element between the two foils frequently results in a marked i~pA;rm4nt in the level of br;ll;Ance and thus an adverse effect on the discernibility of the security element, in part;clllAr under poor lighting conditions. The known ~ocl~nPnt can only be used with difficlllty as a value-bearing paper, in palt;~llAr banknotes, ~ecAu~e it is fundamentally different in t OE ms of its surface nature and other ~Lo~elLies, from the ~ eLLies of paper which are known and fAm;l;Ar in part;~ r in the case of banknotes.
It is also already known from Australian banknotes for printing to be Arplie~ to the surface of transparent carriers in such a way that a given region is left window-like, that is to say transparent. In this case also however the advantages of paper have to be foregone. It is for eA~ple not possible to apply a ~aLæ~ k. In addition the tactile properties which are known to the citizen are different in ~,4~uison with paper (Abs~nce of the par~;clllAr grippy feel). The tried and tested ~u~cG~s;ng and treatment properties as well as the circulation ~L~elLies of paper are also no longer enjoyed. Finally it is not possible in a pure printing ~r~cess to produce specific security elements, for example diffraction structures.
It is also already known to use security threads as security elements in value-bearing documents, the arrangement being such that the thread or a colle~ ;ng strip is superf;c;Ally ~xrose~ in a region-wise ~u~eL in order to be able to check A~; tional security featureswhich are preferably based on optical effects, on the thread or strip, for example printing patterns, diffraction structures etc. European ~ S3~28 patent spe~;f;cAtion No 0 229 645 describes the p m duction of a security paper with an incorE~rated security element in the form of a thread or strip in such a way that two separate layers or plies of paper are formed, the layers of paper having regions of smaller thickness or op~n;n~ therethrough. The two layers of paper are brought together and, during the operation of bringing them together, the strip which serves as the security element is introduced. In that respect the arrangement may also be such that the openings through the two layers of paper (on the top and underside respectively of the strip serving as the security element) co;nc;~e in ~ e~ relat;on~h;r so that the security element is exposed at the same location on the paper web on both sides thereof in order also to permit the security element to be viewed in the tr~nC;lll~;nation mode. In practice however it has been found that it was hitherto not p~ss;ble to p m duce coLL~y~"~;ng documents. In general terms on the contrary the arrangement was only so selected that the security thread or the security element was exposed alternately on the top side and the underside respectively. At any event a serious d;cadvantage of the known ~Luced~re is that, as the security threads have to be incorporated into the paper web, they may only be of comparatively small width in order not to destroy the cohesion of the paper in itself. In order however for the security threads to be of adequate strength in spite of their small width, it is n~c~ss~ry to use security threads of coLLe~ndingly large thickness, which can result in ~mdes;rable increases in the thickness of the value-bearing papers prcduced fram the coLL~onding paper web; in that case, when the value-bearing papers are stacked - in spite of using the so-called wobble or offset procedure - those thickened portions would always be disposed in a relatively narrow region, which results in the sheets not lying ~Lu~Lly flat and gives rise to probl~,~ in ~Luc~ss;ng of the d ~ ~ nt.
The object of the present invention is th~LefuLe that of propos;ng a value-bearing ~o~ ~ nt with a window-like security element suitable for tr~nc;ll~;nation~ which can be prcduced easily and without ~ 63~2~
--adversely affecting the discernibility of the security element, wh;le the problems known in regard to the production of security papers with incol~oLated security thread are not to be expected in the production ~L~c~re. The invention however seeks to ensure that LO19eLY of the security element by pure printing or color copying is impossible, but at the same time there is a large number of diLf~lenL poss;hl~ design configurations for the security element.
In accordance with the invention, in a value-bearing document having at least one security element and at least one window-like through opening which is closed by means of a light-transmitting film, to attain that object, it is proposed that the op~n;~g is subsequently produced in the finished carrier which serves for production of the value-bearing document and is closed by means of an at least region-wise transparent cover foil which projects beyond the op~n;ng on all sides and which is fixed on a surface of the carrier aver the fUll area thereof.
In accordance with the invention therefore the aLL~,~L is no longer made to incorporate a security element into the carrier. On the contrary the opening is ~el;bGrately subsequently produced in the carrier and then the opening is closed again by means of a caver foil which is transparent at least in a region-wise ~ tL, wherein the fact that the cover foil is fixed on the surface of the carrier, aver the full OE ea thereof, means that detachment of the cover foil which possibly carries a security feature which is based for ~x~pl~ on optical effects is practically impossible, without ~Am~ging the carrier. By virtue of the arrangement in accordance with the invention it is readily possible to use a cover foil of c~"~cLd~ively large diTpn~;~n~s~ which means that it is possible to ~eL~Le with cover foils of small thickness. At the same time a pu~ced~re in accordance with the invention also affo~ds the possibility of providing windows of relatively large ~;~pnR;ons~ whereas only ve~y small dimensions could be achieved with the known windows which were produced during the paper production ~r~cess. As the win~
21635~8 can be large, even when there are additional security elements it is read;ly possible for a sufficiently large region of the cover foil to be kept ccmpletely LLalls~cLent. In this case, when a copy is produced using a ~hotoc~;Pr or any other ~Lu~ction a~aLcL~s~ the background will be visible in the region of the window so that the color of the bac~yr~nd appears at that point in the L~lu~ction. In that way foLyeLies can generally be easily detected. Furthermore, the authenticity of the value-bearing ~oc-r~P~t can also be easily detected by the user as the presence or a~sRnce of a Llan~dL~nt region in the value-bearing document can be readily detected even with the naked eye.
The fact that the opening in the carrier is covered over by means of the cover foil affords on the one hand the advantage that the stability.of the value-bearing do~ ~ nt does not suffer, in spite of the presence of one or even more through openings.
Cn the other hand the use of a cover foil affoLds further possihlP
configurations in regard to the security element. V æ iations in the security element are further possible by virtue of ~;fferent shapes for the window-like open;~g or a variation in the posi~io~;ng of the op~n;~g or the provision of a plurality of Op~;n5c which are ~oss;bly of different configurations.
In order to permit easy stacking of value-beAr; ng ~OCl ~ ~ts, in par~i~llAr value-bearing papers such as for ~xAmrle bAnknotes and in order also to make it subs~lLially more difficult to pull off the cover foil and in parti~llAr as far as possible to prevent the cover foil from being unintentionally detached, the cover foil is desirably arranged in a depression in the carrier surface, which depression in~ll~pc the window-like opening, while it is part;~larly advantageous for the carrier to be cu,~Lessed to form the d~L~ssion. The c~n~ession operation simultaneously ~l~u~ls the surface of the carrier, which can be advantageous in regard to certain security features. For PY7m~lP, when security features are ArpliP~ to paper by a hot st~lq~;~g ~Lucess, the optical Pff;ci~n~y thereof is r~du~e~ by the c~l~al~Lively rough 3~8 . 6 surface of the paper, and that can be avoided by suitable smoothing of the surface of the paper, which serves as the carrier.
In accordance with the invention the opening can be easily produced by means of a punching or cutting operation, in which respect mention is to be made here of the usual punching process~s and in part;cllAr laser cutting as a cutting process.
It is basically possihle for the depression and the opening to be produced in separate working operations. In order to avoid special adjusL,I~nL operations and to achieve good Al ;gnTPnt of the opening in relation to the depression, the ~lu~e~re involved is desirably such that the opening is prcduced jointly with the depression in one working operation, and that can be effected for example by using suitable tools, for ~xAmple special stamping and punching rollers.
The operation of producing the depression and applying the cover foil is si~pl;f;e~ when the cover foil e~L~s transversely over the entire width or length of the value-bearing document, that is to say there is a depression f~am one edge to another. Mbre sper;f;cAlly, in such a case the pr~ce~re involved is d~s;rAhly such that the cover foil is Arpl;~ by means of pressure to the carrier of the value-bearing ~ ~ Jnpnt with the d~Lession being fonmed at the same time, the cover foil preferably being laminated on to the carrier in a rolling process.
When using a lamination operation for applying the cover foil to the value-be æ ing document, it is poss;hl~ to achieve a par~;~llArly desirable method of manufacture. Mbre spec;f;~Ally~ in one run through a suitable ~A~h;ne, firstly the window-like opening and possibly also a plurality of openings can be formed, and thereupon the cover foil is A,rrl ;f~ by a lamination procedure in a further step.
For further improving the safeguards against forgery, it is provided in accordance with the invention that, at least on one side of the carrier, the cover foil and at least the adjoining surface region of the value-bearing ~ t are overprinted with an inLeLco,~le~L~
pattern. With such a co~f;~lration, any ~An;p~lAtion on the ccver foil 2163~28 is ;~mP~;~tely visible because it is readily poss;hle to provide printing in which just very slight diSrlAC~ Ls are clearly apparent.
In order to facilitate overprinting of the cover foil, desirably the cover foil may carry a ~n~;ng or primer layer at least on its free side which is not fixed to the value-bearing ~ Pnt or the carrier forming same.
Further possible ways of improving the degree of safeguard against f~L-3ely of a value-bearing document are afforded if, in accordance with the invention, the cover foil is a lAm;nAtion foil ccmprising a Llalls~olenL carrier film and a decorative layer which adheres fixedly thereto, wherein the decorative layer which preferably ;ncll~s at least one 1Ac~r layer is also transparent at least in a portion of the opening. me decorative layer can be of specific graphic configurations using different per se known ~l~cesses in order thereby to afford additional recognition options for an original value-bearing ~o~ ~ ~t.
It is always important however for the decorative layer to be at least partially transparent in ~he region of the opening because it is only then that the effect that the invention seeks primarily to achieve is-still attained.
It may further be desirable for the cover foil to be provided with at least one part;~lar security feature which is based ~lef~a~ly on optical effects, and for at least a portion of the surface region of the opPn;ng to be left transparent, while advan~A~pol~sly at least one security feature is fonmed by a thin-layer arr~n~mPnt and/or ~iffr~ction structure having an optical diffraction and/or refraction effect. Besides such diffraction structures or thin-layer arrAn3~ Ls as the security feature, the COVOE foil may also ;~ ~e for Px~"Lle reflecting surfaces, spec;Al prints, for PXAmpl P in the form of microscript etc. In that respect it is desirable if at least one of the security features is cLL~ly~d in the surface region of the opPn;ng be~AIlse that may then involve for example such a security feature which can be ~leck~d in réspect of authenticity only in the trAnc;lll~;n~Ation - ~163~2~
mode, it being precisely trans;lll~;nAtion ~l~cesses that afford advantages when using automatic testing equipment.
When using a lamination foil as the cover foil, having a decorative layer and at least one diffraction structure as the security feature, the decorative layer is desirably such that it has - starting from the carrier film - a base lAcquPr layer which is provided at least in a region-wise manner at its surface remote from the carrier film with the diffraction structure serving as the security feature, at least in the region of the diffraction structure a reflecting layer, and at least in the region of the opening a transparent protective lacquer layer. In that respect the structure of the decorative layer in the lamination foil in accordance with the invention is in pr;nC;rle the same as the decorative layer structure which is known per se from hot stamping foils for security purposes with a diffraction structure, and as is to be found for PXA~rle in EP 0 559 069 Al. In addition, for applying the various lacquer layers, for introducing the diffraction structure and for pro~vc;ng the metalli~Ation which is possibly only partial, it is AlcO possible to use the ~Locpcses which are known in pr;nc;rlP in connection with the production of hot stamping foils, and for that reason those ~locessPs will not be ~iCc~l~se~ in greater detail here. It will be appreciated that it would also be possible for a diffraction structure to be introduced directly into the carrier foil, that is to say, it would be possible to amit a se~cla~e base lAcq~lPr layer if a suitable carrier foil is used.
If, as the invention further pr~vides, the cover foil is fixed on the carrier in such a way that its decorative layer faces towards the surface of the carrier, that gives on the one hand the advantage that the surface of the cover foil, which carries the decorative layer, is arranged in a virtually recPsse~ or depressed relationship and thus ~LoLecte~ to a certain extent frcm mP~hAn;~Al loA~;ng~. Furthermore, under scme circumstances, it is poss;hlp to cmit a special adhesive Layer for fixing the cover foil on the value-bearing d ~ nlpnt~ namely - 21~J28 .- g when the decorative layer and more spec;~;cAlly at least the L~ s~aL~n~ protective l~c~r layer thereof already has sufficiently adhesive ~Lu~eL~ies, A further possibility in accordance with the invention provides that the decorative layer carries a layer of a har~PnAhlp adhesive, on the side of the decorative layer which is opposite the carrier film, in which respect it is poss;hle to use for PXA~lP reaction adhesives which completely react and thus harden only when subjected to the effect of C~LU~ iate heat or radiation, for ~xAmple IR- or W-radiation. The use of adhesives of that kind has the advantage thatdetach~ent of the cover foil when the adhesive has hardened is e without damage to the value-bearing document itself.
Finally it may be advantageous if the carrier has an Appl;~Ation of adhesive in the region which serves for fixing the cover foil, in which case it is sufficient under some circumstances to provide only that Arpl;~Ation of adhesive on the carrier, although it may also be desirable if, in spite of the A~l;cAtion of adhesive on the carrier, the cover foil is additionally provided with a CULLea~J~ ;ng adhesive layer. If it is only the carrier that is provided with the ~pl;cAtion of adhesive, that gives the advantage that it is poss;kle to avoid adhesive possibly being spread in the region of the op~n;ng.
Further features, details and advantages of the invention will be apparent from the following description of a value-bearing papPr designed in accordance with the invention, with reference to the drawing in which:
Figure 1 is a diay~c~,~Lic view of a value-be æ ing paper of the configuration according to the invention, Figure 2 is a partial cross-section through the value-bearing paper in Figure 1 taken along line II-II in Figure 1, and Figure 3 is a view in section taken along line III-III in Figure 1 through an ~ho~iment of a cover foil, the paper c æ rier of the value-bearing paper having been omitted for the sake of ~nhAnC~ cl æ ity.
~1~3~;~8 The value-bearing paper 1 which is diay~ ically shcwn in Figure 1 can be used in respect of its fll~Ampntal configuration (in - accordance with the invention) for all possible kinds of value-bearing printed matters, for example banknotes, rhG~-~s, travellers' cheques, shares etc, in which respect more detailed features æ e not shown in the drawing and, besides the security ~l~TPnts according to the invention, security measures which æ e otherwise also F~ss;hl~ are not discussed in greater detail. Fur~he~ , a fund mentally co~ ding structure is also intended for other value-be æ ing documents, for example credit c æ ds, identity c æ ds or the like.
The value-bearing paper shown in Figure 1 ccmprises a paper carrier 2 which can be provided for example in the manner known from banknotes with a watenmark, with special imprints thereon and other security elements, like one diay~ Lically ;n~irated for PXA~ at 3. The security element 3 can be for ~Y~m~le in the form of a spec; Al microprint. It may however also be a sper;f;r ~mkoss;ng or s~mr;~g, a reflecting embossing or stamping etc. Norm~lly, in production of the value-be æ ing paper 1, the paper carrier 2 is part of a web of paper or a sheet of paper f m m which the value-bearing paper 1 is cut after production. In the case of other value-bearing ~rx~Pnts as the value-bearing p_pers, another suitable carrier which p~ss;hly already has a security element, for example a plastic card or foil, is used.
As shown in Figures 1 and 2, the carrier 2 has at least one window-like through ope~; ng 4 which i.5 rl OSP~ by m~eans of a cover foil 5, wherein the cover foil 5 i5 fixed over the full area on the one surface 6 of the carrier 2, preferably by adhesive, so that it projects at all sides beyond the window-like opening 4, as can be seen from Figures 1 and 2, so that the cover foil 5 a~lh~L~s firmly to the surface 6 of the carrier 2 around the op~n;ng 4 in the regions 7 (Figure 2).
It can be seen in p æ t;~lAr frcm Figure 2 that the cover foil is arranged in a depression 8 in the surface 6 of the carrier 2 so that, in the finished value-be æ ing paper 1, the co~er foil does not cause a ~6;3~2~
s~sLallLial increase in the thickness of the value-bearing document, and that is imFortant in parti~lAr when a multipl;city of value-bearing documents is to be stacked. The security threads which were known hitherto in relation to value-bearing papers are only relatively n3~w and must theLe~oL~ be cnmr~rAtively thick for mechAn;~Al reasons.
In that case however they project far above the surface of the value-bearing paper and, when value-bearing ~ocl~Pnts are stacked, those threads, in the region thereof, result in an lm~Ps;rable increase in the thickness of the stacks, which poss;hly makes production and automatic handling of the value-bearing ~a~eL~ more difficult.
The depression 8 is produced by the paper carrier 2 being cull~L~ssed in the region of the depression 8. That can be effected in a simple manner simultaneously with the operation of applying the cover foil 5 to the surface 6 of the carrier 2, re specific~lly by a procedure whereby, when the cover foil 5 is Ar~l;P~ to the surface 6 of the carrier 2, a co~Le~ondingly high pressure is ~rpl;P~, which results in ~eL~ ent c~ ssion of the carrier 2.
As Figure 1 shows the depression 8 for the cover foil 5 ~xLellds over the entire width of the carrier 2 from itslower e~ge 9 to the top edge 10. That co~f;~ration affords the advantage that both the operation of applying the cover foil 5 and also the o~LcLion of form;ng the depression 8 can be effected in a rolling process by means of suitable rolls or rollers, which aLfoL~s the poss;h;l;ty of providing the value-bearing paper 1 with the cover foil 5 in a continuous process, wherein, in a step prece~;~g the operation of applying the cover foil 5, the window-like opening can be produced by p-n~h;~, which in fact can also be ~eLrv~d in a rolling ~Lucess. In that Les~ecL, if the tool is of a suitable conf;~lr~tion~ the ~lnch;ng operation can be cnTb; nP~ with the c~l~u~ssion operation, in one wor~ing procedure.
- 2163~28 -Figure 1 shows that the cover foil 5 is LL~I~CL~nL only in a portion of the window-like op~n;ng 4, namely the outer region 11, while provided in the inner region of the op~ning 4 is an additional security feature 12 which is based for PY~m~lP on optical effects, for ~Am~le in the form of a diffraction structure which is operative in a Lan~,~ssion mode. However, the additional security element 12 in the window-like opening 4 can not only be fonTP~ by a diffraction structure having an optical-diffraction and/or optical-refraction effect, for ~XA~1 e a hologram, a pixelgram etc. It would also be pnss;ble to choose as the additional security element 12 for ~XAmple a reflecting surface, a par~ n microprint, a thin-layer arrangement or some other configuration which can only be imitated with difficulty.
In addition, as shown in Figure 1, outside the region CO1L~ g to the window-like opening the cover foil may be provided with at least one additional security feature 13 which is bARed for ~Y~mrle on optical effects, which security feature 13 can also be of the most widely varying kinds and natures in ~pGn~nce on the material of the cover foil, any coating thereon etc.
In accordance with the invention un~ ;red detA~hmpnt of the cover foil 5 fram the surface 6 of the carrier 2 is made more difficult by virtue of the fact that the cover foil 5 and the adjoining regions of the surface 6 of the carrier 2 are overprinted with an inteLco~ected ~aLL~L.l 14. That operation of printing the ~G~LeL~ 14 can also be effected in the continuous process already mentioned above, in a process step which occurs downstream of the operation of applying the cover foil 5.
It will be seen fram the foregoing that a value-bearing ~o~nt, for ~XA~1 e a value-bear m g paper 1 in accordance with the invention, arroL~s a large number of further options in regard to the provision of security features, in cu"~aLison with the previously known value-bearing ~oc~ ~ nts, but in that respect it is ~vcr always n~cPcs~ry to ensure that the cover foil 5 is h ~ ~aLe~lt at least in a region--. ~16~5~
wise "~eL, in the region of the at least one window-like opening 4 -it will be appreciated that a plurality of opPnin~s could also be provided - because it is only then that it is poss;hle to carry out a checking operation using the naked eye and it is only in such a case that an optical falsification effect occurs, upon an attempt at u~ction by means of color copying or printing, in the LL~ ~ale"l region within the opening 4. That fAlc;f;cAtion effect occurs in fact totally irrespective of which color is selected for the backyL~und in the copying operation, beca~l~e the COl~ e~onding region is not LLans~aLent in any case.
Figure 3 diagrammatically shows a lam m ation foil as can be used as the cover foil 5 for the value-bearing paper 1 in Figures 1 and 2.
That cover foil S in Figure 3 comerises a L~ ellt carrier filn 15. On its surface which is remote from the decorative layer 16, it is provided with a thin bonding or primer layer 17 which is intended to ensure that the pattern 14 which is A~Fl;P~ by printing adheres finmly to the carrier film 15. -The opposite surface of the carrier film 15 is also provided with abonding or pr imer layer 18 which is intended to ensure adequate A~ S;On of the decorative layer 16 on the r~rrier fi~m 15.
In the Gmh~d;mPnt shown in Figure 3 the decorative layer 16 -coLL~L.~ ;ng to the view shown in Figure 1 - is provided with diffeL~n~ security features 12, 13, both cases involving diffraction structures in accordance with the foregoing description.
For that purpose the decorative layer 16 ~as a ther-,~plastically deforT~ble base lAcquPr layer 19. Different diffraction structures 20 and 21 respectively are provided in that base lAcq~ler layer 19 in the regions cuLL~onding to the security features 12, 13, in which case the diffraction structures 20, 21 are pro~ce~ by suitable e~boss;ng of the ll~s~ lActically ~PfornAhle base 1AC~1~r layer 19 after the ~Appl;rAJtion thereof to the carrier film 15.
-- ~16~5~8 : 14 It will be appreciated that the diffraction structures 20, 21 are only visible at the cover foil 5 when the layers Pnclos;ng the diffraction structures 20, 21 have suitably different optical properties. For PxAmple, in the case of the diffraction structure 20 of the security feature 12, that is achieved in that a reflecting metal coating 22 is provided in the region of the diffraction structure 20;
the metal layer 22 may ~e for example an aluminium layer which is produced by vapor deposition in a vacuum or a layer, A~pl;P~ in a suitable manner, of another material which is known to be suitable.
Another possible way of rendering the diffraction structures 20, 21 visible provides that a suitable dielectric, for example TiO2 or TnS is Arpl;~ in the region of the diffraction structures 20, 21.
Then, in relation to the cover foil 5, the diffraction structure is covered over by means of a transparent protective lAcq~Pr layer 23 which in turn can carry a b~;ng or primer layer 24, at least in the region of the opening 4, in which ~ ec~ the bo~;ng or primer layer 24 has in par~ r t~e purpose of promoting A~hPs;on of the cover foil 5 to the surface 6 of the carrier 2. In addition however it may also favour a printing operation which is poss;hly to be s~bse~ Pntly effected - when de~Al;n~ with CO1Le~O~-1;ng1Y thin value-be æ ing ~oclrnPnts or in the case of l æ ge opPn;n~q - on the side of the cover foil, which is remote fL~" the surface 6 of the carrier 2, in the region of the opening or openings 4.
While the protective 1AC~lPr layer 23 is usually colorless - to fA~;l;tate identification of the security element - it can certainly ~e provided that, b~Ps;~es its diffraction effect, the second security feature 13 is dist;n~l;che~ by a par~ r coloring. In the case of the foil shown in Figure 3 for PXA~rle that is achieved by the diffraction structure 21 of the security feature 13 being covered with a ~ -Y~ t but colored l~c~)Pr layer 25 prior to the arpl;~tion of the p¢otective l~cquPr layer 23.

Mbre specifically a cover foil 5 as shown in Figure 3 could be of the following structure:
Bonding or primer layers 17, 18 and 24:
These layers are of a thickness of 0.2 to 2, ~lefeLably 0.5 to 1.2 S ~m. The bonding or primer layers 17 and 24 can possibly be omitted, more espe~iAlly in partictllAr when sllbse~)Ptlt overprinting of the cover foil is not envisaged.
The bonding or primer layers are ~rpl;P~ by a per se known printing process, in which respect they may be of the following composition:
Parts by weight Methyl ethyl ketone 400 Toluene 250 Cyclohexanone S0 Hydroxyl group-bearing vinyl chloride vinyl acetate terpolymer (Tg = 79CC, MW about 23,000) 210 Vinyl chloride vinyl acetate copolymer (MW about 4,000) 90 Carrier film 15:
This involves a suitable, optically clear, that is to say ~elLec~ly ~ s~2uent, film which should be as thin as poss;hlp in order not to stick up on the value-bearing paper, but on the other hand it must afford adequate strength. Polyester (PET) or pol~ccu~onate (PC) films of a thickness of between 6 and 12 ~m have been found to be suitable.
Thermoplastically defonmable base lacq~lPr layer 19:
This layer is of a thickness of usually 0.8 to 2 ~ , the thickness of the layer deF~;ng on the nature of the structure to be Arrl;P~
thereto, The base 1~C~Pr layer 19 is also Aprl;P~ by a printing ~Lucess and can be for Px~-~le of the following c~lL~s;tion:
2~63~2~
-Parts by weight Ethyl acetate 350 Toluene 200 Butyl acetate 130 Polymethyl methacrylate (softening point about 170C) 270 Styrene copolymer 5 (softening point about 100C) 50 Diffraction structures 20, 21:
These structures are known per se and are ~Tbocs~ into the base l~c~lPr layer 19 by means of suitable dies. The me~A~ Ation 22 comprises for example aluminium, chromium, gold or silver, Appl;e~ in a vacuum; depending on the material used pulverization can be effected by suitable ~Locesses, for example by vaporization, sputtering etc.
Instead of the metal layer it is also po~s;~le to apply a suitable dielectric, for example TiO2 or ZnS. Desirably, metAll;~Ation is Arrl;e~ over the entire, suitably shaped surface of the ~ Actic base 1ACqUPr layer 19 and then partially removed using a known ~L~cess.
There are different processPs in that respect, in which case in part;~-lAr those ~L~cesses are used in which, prior to the A~pl;~Ation of the metal layer, the structured surface of the ~ "~,~lActic base lac~Pr layer 19 is provided with a de~A~hAble layer in the unstructured regions, for ex_mple by printing in suitable register rela~io~h;r. After the metA~ Ation operation th_t det~rhA~lP layer is then removed again and thus the metA~ Ation is removed again in the region of the detA~hablP layer. The thickness of the me~All;7Ation or the dielectric layer is for ~XAmrle 60 to 20 A.
Transparent protective lacquer layer 23:
This layer is of a thickness of 1 to 5 ~m, ~L~L~Lably 2 to 3 ym, in which L~s~ec~ the thickness can be less in the regions where the additional lAcg~l~r layer 25 is provided than in the regions without an additional lacqupr layer of that kind. Moreover the thickness of the -- ~16352~
: 17 protective lacquer layer 23 ~ n~ on the L~ecLive ~P~.hAn;cAl requiL~,~nLs; in that Les~ecL, they are nornAlly not PxcPss;vely high becAllce on the one hand the size of the opening 4 is restricted and on the other hand the cover foil 5 is preferably A~pl;PA to the surface 6 of the carrier 2 in such a way that the decorative layer 16 faces towards the surface 6 of the carrier 2 so that the heavy mechanical loading occurs on the side of the carrier film 15.
The transparent protective lacqu~r layer can be for PxA~plP of the following c~T~os;tion:
Parts by weight Methyl ethyl ketone 300 Ethyl acetate 170 Cy~l ~h~xArlone 100 Hydrofunctional acrylate 15 (60% in Xylene/EPA, OH-number 140) 200 CP~ lose nitrate (low-viscosity, 65% in Alcohol) 80 Aromatic isocyanate (50% in ethyl acetate, NKC~content 8%) 150 The protective 1~ACqUPr layer 23 and possibly the additional lA~quer layer 25 are normally Arpl;P~ by a printing process, in which case the additional l~cquPr layer 25 is to be A~pl;PA by printing prior to the protective lAc9~1~r layer 23. In regard to the c~T~os;tion of the additional transparent lAcq~lPr layer 25, it is to be noted that this can be of substantially the same crT~.os;tion as the ~LuLe~Live 1AC9~l~r layer 23, but additionally contains a h ~ ~arent coloring agent.
In production of a value-be æ ing ~ex~Pnt, for example a value-be æ ing paper 1 in accordance with the invention therefore firstly the cover foil 5 is produced, for ~nple in a manner which is basically known from the production of hot S~AmP; ng foils, although the difference between the cover foil 5 and a hot stamping foil is that, in the case of the cover foil 5, care is taken to ensure that the dec~La~ive layer 16 adheres firmly to the c æ rier filn 15 while the -- ~16~52~
ess~nce of a hot stamp;~g foil is in fact precisely to be seen in the fact that the decorative layer can be eas;ly detached from the carri OE
fil~.
The cover foil is then Arpl;P~ to the carrier 2 of the value-bearing document, for example a value-bearing paper 1, preferably in a cont;nuouC rolling ~l~ce~re, in which case the window-like opPn;~g 4 is desirably produced in a first working operation, for e~Amrle by p~lnçh;ng. Subsequently or at the same time the carrier 2 is c~n~u~ssed to produce the depression 8, which can be effected for PXA~rlP by means of rollers, using suitably high pressures. Now, the cover foil 5 is A~p~ to the surface 6 of the carrier 2, by rolling. Fixing of the cover foil S on the carrier 2 can be effected by the protective l~c~)Pr layer 23 or the bonding or primer layer 24 of the decorative layer 16 of the cover foil 5 having suitable adhesive y~u~e~ies or by the decorative layer 16 of the cover foil 5 addit;onAlly being provided with a har~PnAhle adhesive layer (not shown). A further option is that, prior to the Appl;cation of the cover foil 5, the surface 6 of the carrier 2 is provided in the region of the depression 8 with an ~ppl;cAtion of adhesive, by means of which the cover foil 5 is then fixed to the carrier 2. Which of the two measures is adu~ed ~n~s on the nature or comFosition of the carrier 2, the decorative layer 16 of the cover foil 5 and the Le~kecLive purpose of use, in which .es~ecL it is also conceivable for adhesive to be p~ovided both on the cover foil 5 and also on the carrier 2.
After appl;cAtion of the cover foil 5 the surface 6 and poss;hly also the underside of the carrier 2 can then also be overprinted with the in~e~colmected ~aLLeL~I 14 by means of a conventional printing ~uocess for further ~nh~nc;ng the security aspect. Fin~lly when prc~lc~ng value-bearing papers the individual value-bearing papers are cut out of the paper cnmh;~e (web, sheets) fo~;n~ a rlllr~l;ty of carriers 2.

. 19 -The described e~kc~impnt of the value-bearing document involves a value-bearing p2per. However the concept of the invention can also be pl;e~ in the same ~ eL in relation to value-bearing ~ocl ~ nts consisting of materials other than paper, for example credit cards, identity cards etc.
Value-bearing document with window The invention concPrns value-bearing documents, in parti~llar value-bearing papers, such as for example banknotes, cheques, travellers' cheques or share certificates, but also documents which do not consist of paper or which only partially consist of paper, for example credit cards, identity cards etc.
Parti~-lArly having regard to the options afforded by modern color copiers and other L~Lu~ucing systems, there is an urgent need for value-bearing documents to be provided with special security elements which make it difficult to produce a forgery using items of e~lirmPnt of that kind. A l OE ge nu~ber of possible procedures have already been proposed for that purpose.
It is known for ex~il~le for value-bearing documents such as value-bearing papers, c OEds, identity cards etc to be provided with security elements in the form of reflecting surfaces. Those reflecting surfaces OE e normally reproduced by a color copier as black surfaces. In this case however there is the possibility of subsequently applying a suitable, me~al 1 ;CA1 ly shiny layer.
A further improvement in affording a safeguard against forgery is achieved when security elements in the form of structures which have an optical-diffraction or optical-refraction effect, so-called diffraction structures, for example holograms, so-called pixelgrams etc OEe used.
However those security elements æe cull~aLa~ively Pxp~ive in tenms of production.
It is also already known for security elements for value-be OE ing documents to be so designed that they æ e suitable in partiClllAr for viewing in a transilll~;nation mode. For Px~"L)le AU-patent specificAtion No 488 652 describes security ~o~nts which comprise a plurality of interconnected plastic webs, wherein at least one optically variable security element is arranged between those webs and a I ~ ~aLenL window is provided in at least one of the cover webs in the region of the security element so that the security element can be viewed through the window. For applying the security elements, in accordance with the state of the art for P~AT~le the lJ ~ lre is such that an openinq is pro~ P~
in a plastic web which is disposed in the int OE ior of the ~oK~nPnt~ the security element being fitted into the opening. The security element is then fixed in the opening by cover foil~ which are Apr~ at both sides. A ~L~ced~re of that kind suffers on the one hand fron the disadvantage that the operation of applying the security element gives rise to major difficulties and in p æ ~ lAr the ~Loced~re requires lamination over the full surface areas of cu"~aLaLively l æ ge regions of plastic foils. Tncll~;on of the security element between the two foils frequently results in a marked i~pA;rm4nt in the level of br;ll;Ance and thus an adverse effect on the discernibility of the security element, in part;clllAr under poor lighting conditions. The known ~ocl~nPnt can only be used with difficlllty as a value-bearing paper, in palt;~llAr banknotes, ~ecAu~e it is fundamentally different in t OE ms of its surface nature and other ~Lo~elLies, from the ~ eLLies of paper which are known and fAm;l;Ar in part;~ r in the case of banknotes.
It is also already known from Australian banknotes for printing to be Arplie~ to the surface of transparent carriers in such a way that a given region is left window-like, that is to say transparent. In this case also however the advantages of paper have to be foregone. It is for eA~ple not possible to apply a ~aLæ~ k. In addition the tactile properties which are known to the citizen are different in ~,4~uison with paper (Abs~nce of the par~;clllAr grippy feel). The tried and tested ~u~cG~s;ng and treatment properties as well as the circulation ~L~elLies of paper are also no longer enjoyed. Finally it is not possible in a pure printing ~r~cess to produce specific security elements, for example diffraction structures.
It is also already known to use security threads as security elements in value-bearing documents, the arrangement being such that the thread or a colle~ ;ng strip is superf;c;Ally ~xrose~ in a region-wise ~u~eL in order to be able to check A~; tional security featureswhich are preferably based on optical effects, on the thread or strip, for example printing patterns, diffraction structures etc. European ~ S3~28 patent spe~;f;cAtion No 0 229 645 describes the p m duction of a security paper with an incorE~rated security element in the form of a thread or strip in such a way that two separate layers or plies of paper are formed, the layers of paper having regions of smaller thickness or op~n;n~ therethrough. The two layers of paper are brought together and, during the operation of bringing them together, the strip which serves as the security element is introduced. In that respect the arrangement may also be such that the openings through the two layers of paper (on the top and underside respectively of the strip serving as the security element) co;nc;~e in ~ e~ relat;on~h;r so that the security element is exposed at the same location on the paper web on both sides thereof in order also to permit the security element to be viewed in the tr~nC;lll~;nation mode. In practice however it has been found that it was hitherto not p~ss;ble to p m duce coLL~y~"~;ng documents. In general terms on the contrary the arrangement was only so selected that the security thread or the security element was exposed alternately on the top side and the underside respectively. At any event a serious d;cadvantage of the known ~Luced~re is that, as the security threads have to be incorporated into the paper web, they may only be of comparatively small width in order not to destroy the cohesion of the paper in itself. In order however for the security threads to be of adequate strength in spite of their small width, it is n~c~ss~ry to use security threads of coLLe~ndingly large thickness, which can result in ~mdes;rable increases in the thickness of the value-bearing papers prcduced fram the coLL~onding paper web; in that case, when the value-bearing papers are stacked - in spite of using the so-called wobble or offset procedure - those thickened portions would always be disposed in a relatively narrow region, which results in the sheets not lying ~Lu~Lly flat and gives rise to probl~,~ in ~Luc~ss;ng of the d ~ ~ nt.
The object of the present invention is th~LefuLe that of propos;ng a value-bearing ~o~ ~ nt with a window-like security element suitable for tr~nc;ll~;nation~ which can be prcduced easily and without ~ 63~2~
--adversely affecting the discernibility of the security element, wh;le the problems known in regard to the production of security papers with incol~oLated security thread are not to be expected in the production ~L~c~re. The invention however seeks to ensure that LO19eLY of the security element by pure printing or color copying is impossible, but at the same time there is a large number of diLf~lenL poss;hl~ design configurations for the security element.
In accordance with the invention, in a value-bearing document having at least one security element and at least one window-like through opening which is closed by means of a light-transmitting film, to attain that object, it is proposed that the op~n;~g is subsequently produced in the finished carrier which serves for production of the value-bearing document and is closed by means of an at least region-wise transparent cover foil which projects beyond the op~n;ng on all sides and which is fixed on a surface of the carrier aver the fUll area thereof.
In accordance with the invention therefore the aLL~,~L is no longer made to incorporate a security element into the carrier. On the contrary the opening is ~el;bGrately subsequently produced in the carrier and then the opening is closed again by means of a caver foil which is transparent at least in a region-wise ~ tL, wherein the fact that the cover foil is fixed on the surface of the carrier, aver the full OE ea thereof, means that detachment of the cover foil which possibly carries a security feature which is based for ~x~pl~ on optical effects is practically impossible, without ~Am~ging the carrier. By virtue of the arrangement in accordance with the invention it is readily possible to use a cover foil of c~"~cLd~ively large diTpn~;~n~s~ which means that it is possible to ~eL~Le with cover foils of small thickness. At the same time a pu~ced~re in accordance with the invention also affo~ds the possibility of providing windows of relatively large ~;~pnR;ons~ whereas only ve~y small dimensions could be achieved with the known windows which were produced during the paper production ~r~cess. As the win~
21635~8 can be large, even when there are additional security elements it is read;ly possible for a sufficiently large region of the cover foil to be kept ccmpletely LLalls~cLent. In this case, when a copy is produced using a ~hotoc~;Pr or any other ~Lu~ction a~aLcL~s~ the background will be visible in the region of the window so that the color of the bac~yr~nd appears at that point in the L~lu~ction. In that way foLyeLies can generally be easily detected. Furthermore, the authenticity of the value-bearing ~oc-r~P~t can also be easily detected by the user as the presence or a~sRnce of a Llan~dL~nt region in the value-bearing document can be readily detected even with the naked eye.
The fact that the opening in the carrier is covered over by means of the cover foil affords on the one hand the advantage that the stability.of the value-bearing do~ ~ nt does not suffer, in spite of the presence of one or even more through openings.
Cn the other hand the use of a cover foil affoLds further possihlP
configurations in regard to the security element. V æ iations in the security element are further possible by virtue of ~;fferent shapes for the window-like open;~g or a variation in the posi~io~;ng of the op~n;~g or the provision of a plurality of Op~;n5c which are ~oss;bly of different configurations.
In order to permit easy stacking of value-beAr; ng ~OCl ~ ~ts, in par~i~llAr value-bearing papers such as for ~xAmrle bAnknotes and in order also to make it subs~lLially more difficult to pull off the cover foil and in parti~llAr as far as possible to prevent the cover foil from being unintentionally detached, the cover foil is desirably arranged in a depression in the carrier surface, which depression in~ll~pc the window-like opening, while it is part;~larly advantageous for the carrier to be cu,~Lessed to form the d~L~ssion. The c~n~ession operation simultaneously ~l~u~ls the surface of the carrier, which can be advantageous in regard to certain security features. For PY7m~lP, when security features are ArpliP~ to paper by a hot st~lq~;~g ~Lucess, the optical Pff;ci~n~y thereof is r~du~e~ by the c~l~al~Lively rough 3~8 . 6 surface of the paper, and that can be avoided by suitable smoothing of the surface of the paper, which serves as the carrier.
In accordance with the invention the opening can be easily produced by means of a punching or cutting operation, in which respect mention is to be made here of the usual punching process~s and in part;cllAr laser cutting as a cutting process.
It is basically possihle for the depression and the opening to be produced in separate working operations. In order to avoid special adjusL,I~nL operations and to achieve good Al ;gnTPnt of the opening in relation to the depression, the ~lu~e~re involved is desirably such that the opening is prcduced jointly with the depression in one working operation, and that can be effected for example by using suitable tools, for ~xAmple special stamping and punching rollers.
The operation of producing the depression and applying the cover foil is si~pl;f;e~ when the cover foil e~L~s transversely over the entire width or length of the value-bearing document, that is to say there is a depression f~am one edge to another. Mbre sper;f;cAlly, in such a case the pr~ce~re involved is d~s;rAhly such that the cover foil is Arpl;~ by means of pressure to the carrier of the value-bearing ~ ~ Jnpnt with the d~Lession being fonmed at the same time, the cover foil preferably being laminated on to the carrier in a rolling process.
When using a lamination operation for applying the cover foil to the value-be æ ing document, it is poss;hl~ to achieve a par~;~llArly desirable method of manufacture. Mbre spec;f;~Ally~ in one run through a suitable ~A~h;ne, firstly the window-like opening and possibly also a plurality of openings can be formed, and thereupon the cover foil is A,rrl ;f~ by a lamination procedure in a further step.
For further improving the safeguards against forgery, it is provided in accordance with the invention that, at least on one side of the carrier, the cover foil and at least the adjoining surface region of the value-bearing ~ t are overprinted with an inLeLco,~le~L~
pattern. With such a co~f;~lration, any ~An;p~lAtion on the ccver foil 2163~28 is ;~mP~;~tely visible because it is readily poss;hle to provide printing in which just very slight diSrlAC~ Ls are clearly apparent.
In order to facilitate overprinting of the cover foil, desirably the cover foil may carry a ~n~;ng or primer layer at least on its free side which is not fixed to the value-bearing ~ Pnt or the carrier forming same.
Further possible ways of improving the degree of safeguard against f~L-3ely of a value-bearing document are afforded if, in accordance with the invention, the cover foil is a lAm;nAtion foil ccmprising a Llalls~olenL carrier film and a decorative layer which adheres fixedly thereto, wherein the decorative layer which preferably ;ncll~s at least one 1Ac~r layer is also transparent at least in a portion of the opening. me decorative layer can be of specific graphic configurations using different per se known ~l~cesses in order thereby to afford additional recognition options for an original value-bearing ~o~ ~ ~t.
It is always important however for the decorative layer to be at least partially transparent in ~he region of the opening because it is only then that the effect that the invention seeks primarily to achieve is-still attained.
It may further be desirable for the cover foil to be provided with at least one part;~lar security feature which is based ~lef~a~ly on optical effects, and for at least a portion of the surface region of the opPn;ng to be left transparent, while advan~A~pol~sly at least one security feature is fonmed by a thin-layer arr~n~mPnt and/or ~iffr~ction structure having an optical diffraction and/or refraction effect. Besides such diffraction structures or thin-layer arrAn3~ Ls as the security feature, the COVOE foil may also ;~ ~e for Px~"Lle reflecting surfaces, spec;Al prints, for PXAmpl P in the form of microscript etc. In that respect it is desirable if at least one of the security features is cLL~ly~d in the surface region of the opPn;ng be~AIlse that may then involve for example such a security feature which can be ~leck~d in réspect of authenticity only in the trAnc;lll~;n~Ation - ~163~2~
mode, it being precisely trans;lll~;nAtion ~l~cesses that afford advantages when using automatic testing equipment.
When using a lamination foil as the cover foil, having a decorative layer and at least one diffraction structure as the security feature, the decorative layer is desirably such that it has - starting from the carrier film - a base lAcquPr layer which is provided at least in a region-wise manner at its surface remote from the carrier film with the diffraction structure serving as the security feature, at least in the region of the diffraction structure a reflecting layer, and at least in the region of the opening a transparent protective lacquer layer. In that respect the structure of the decorative layer in the lamination foil in accordance with the invention is in pr;nC;rle the same as the decorative layer structure which is known per se from hot stamping foils for security purposes with a diffraction structure, and as is to be found for PXA~rle in EP 0 559 069 Al. In addition, for applying the various lacquer layers, for introducing the diffraction structure and for pro~vc;ng the metalli~Ation which is possibly only partial, it is AlcO possible to use the ~Locpcses which are known in pr;nc;rlP in connection with the production of hot stamping foils, and for that reason those ~locessPs will not be ~iCc~l~se~ in greater detail here. It will be appreciated that it would also be possible for a diffraction structure to be introduced directly into the carrier foil, that is to say, it would be possible to amit a se~cla~e base lAcq~lPr layer if a suitable carrier foil is used.
If, as the invention further pr~vides, the cover foil is fixed on the carrier in such a way that its decorative layer faces towards the surface of the carrier, that gives on the one hand the advantage that the surface of the cover foil, which carries the decorative layer, is arranged in a virtually recPsse~ or depressed relationship and thus ~LoLecte~ to a certain extent frcm mP~hAn;~Al loA~;ng~. Furthermore, under scme circumstances, it is poss;hlp to cmit a special adhesive Layer for fixing the cover foil on the value-bearing d ~ nlpnt~ namely - 21~J28 .- g when the decorative layer and more spec;~;cAlly at least the L~ s~aL~n~ protective l~c~r layer thereof already has sufficiently adhesive ~Lu~eL~ies, A further possibility in accordance with the invention provides that the decorative layer carries a layer of a har~PnAhlp adhesive, on the side of the decorative layer which is opposite the carrier film, in which respect it is poss;hle to use for PXA~lP reaction adhesives which completely react and thus harden only when subjected to the effect of C~LU~ iate heat or radiation, for ~xAmple IR- or W-radiation. The use of adhesives of that kind has the advantage thatdetach~ent of the cover foil when the adhesive has hardened is e without damage to the value-bearing document itself.
Finally it may be advantageous if the carrier has an Appl;~Ation of adhesive in the region which serves for fixing the cover foil, in which case it is sufficient under some circumstances to provide only that Arpl;~Ation of adhesive on the carrier, although it may also be desirable if, in spite of the A~l;cAtion of adhesive on the carrier, the cover foil is additionally provided with a CULLea~J~ ;ng adhesive layer. If it is only the carrier that is provided with the ~pl;cAtion of adhesive, that gives the advantage that it is poss;kle to avoid adhesive possibly being spread in the region of the op~n;ng.
Further features, details and advantages of the invention will be apparent from the following description of a value-bearing papPr designed in accordance with the invention, with reference to the drawing in which:
Figure 1 is a diay~c~,~Lic view of a value-be æ ing paper of the configuration according to the invention, Figure 2 is a partial cross-section through the value-bearing paper in Figure 1 taken along line II-II in Figure 1, and Figure 3 is a view in section taken along line III-III in Figure 1 through an ~ho~iment of a cover foil, the paper c æ rier of the value-bearing paper having been omitted for the sake of ~nhAnC~ cl æ ity.
~1~3~;~8 The value-bearing paper 1 which is diay~ ically shcwn in Figure 1 can be used in respect of its fll~Ampntal configuration (in - accordance with the invention) for all possible kinds of value-bearing printed matters, for example banknotes, rhG~-~s, travellers' cheques, shares etc, in which respect more detailed features æ e not shown in the drawing and, besides the security ~l~TPnts according to the invention, security measures which æ e otherwise also F~ss;hl~ are not discussed in greater detail. Fur~he~ , a fund mentally co~ ding structure is also intended for other value-be æ ing documents, for example credit c æ ds, identity c æ ds or the like.
The value-bearing paper shown in Figure 1 ccmprises a paper carrier 2 which can be provided for example in the manner known from banknotes with a watenmark, with special imprints thereon and other security elements, like one diay~ Lically ;n~irated for PXA~ at 3. The security element 3 can be for ~Y~m~le in the form of a spec; Al microprint. It may however also be a sper;f;r ~mkoss;ng or s~mr;~g, a reflecting embossing or stamping etc. Norm~lly, in production of the value-be æ ing paper 1, the paper carrier 2 is part of a web of paper or a sheet of paper f m m which the value-bearing paper 1 is cut after production. In the case of other value-bearing ~rx~Pnts as the value-bearing p_pers, another suitable carrier which p~ss;hly already has a security element, for example a plastic card or foil, is used.
As shown in Figures 1 and 2, the carrier 2 has at least one window-like through ope~; ng 4 which i.5 rl OSP~ by m~eans of a cover foil 5, wherein the cover foil 5 i5 fixed over the full area on the one surface 6 of the carrier 2, preferably by adhesive, so that it projects at all sides beyond the window-like opening 4, as can be seen from Figures 1 and 2, so that the cover foil 5 a~lh~L~s firmly to the surface 6 of the carrier 2 around the op~n;ng 4 in the regions 7 (Figure 2).
It can be seen in p æ t;~lAr frcm Figure 2 that the cover foil is arranged in a depression 8 in the surface 6 of the carrier 2 so that, in the finished value-be æ ing paper 1, the co~er foil does not cause a ~6;3~2~
s~sLallLial increase in the thickness of the value-bearing document, and that is imFortant in parti~lAr when a multipl;city of value-bearing documents is to be stacked. The security threads which were known hitherto in relation to value-bearing papers are only relatively n3~w and must theLe~oL~ be cnmr~rAtively thick for mechAn;~Al reasons.
In that case however they project far above the surface of the value-bearing paper and, when value-bearing ~ocl~Pnts are stacked, those threads, in the region thereof, result in an lm~Ps;rable increase in the thickness of the stacks, which poss;hly makes production and automatic handling of the value-bearing ~a~eL~ more difficult.
The depression 8 is produced by the paper carrier 2 being cull~L~ssed in the region of the depression 8. That can be effected in a simple manner simultaneously with the operation of applying the cover foil 5 to the surface 6 of the carrier 2, re specific~lly by a procedure whereby, when the cover foil 5 is Ar~l;P~ to the surface 6 of the carrier 2, a co~Le~ondingly high pressure is ~rpl;P~, which results in ~eL~ ent c~ ssion of the carrier 2.
As Figure 1 shows the depression 8 for the cover foil 5 ~xLellds over the entire width of the carrier 2 from itslower e~ge 9 to the top edge 10. That co~f;~ration affords the advantage that both the operation of applying the cover foil 5 and also the o~LcLion of form;ng the depression 8 can be effected in a rolling process by means of suitable rolls or rollers, which aLfoL~s the poss;h;l;ty of providing the value-bearing paper 1 with the cover foil 5 in a continuous process, wherein, in a step prece~;~g the operation of applying the cover foil 5, the window-like opening can be produced by p-n~h;~, which in fact can also be ~eLrv~d in a rolling ~Lucess. In that Les~ecL, if the tool is of a suitable conf;~lr~tion~ the ~lnch;ng operation can be cnTb; nP~ with the c~l~u~ssion operation, in one wor~ing procedure.
- 2163~28 -Figure 1 shows that the cover foil 5 is LL~I~CL~nL only in a portion of the window-like op~n;ng 4, namely the outer region 11, while provided in the inner region of the op~ning 4 is an additional security feature 12 which is based for PY~m~lP on optical effects, for ~Am~le in the form of a diffraction structure which is operative in a Lan~,~ssion mode. However, the additional security element 12 in the window-like opening 4 can not only be fonTP~ by a diffraction structure having an optical-diffraction and/or optical-refraction effect, for ~XA~1 e a hologram, a pixelgram etc. It would also be pnss;ble to choose as the additional security element 12 for ~XAmple a reflecting surface, a par~ n microprint, a thin-layer arrangement or some other configuration which can only be imitated with difficulty.
In addition, as shown in Figure 1, outside the region CO1L~ g to the window-like opening the cover foil may be provided with at least one additional security feature 13 which is bARed for ~Y~mrle on optical effects, which security feature 13 can also be of the most widely varying kinds and natures in ~pGn~nce on the material of the cover foil, any coating thereon etc.
In accordance with the invention un~ ;red detA~hmpnt of the cover foil 5 fram the surface 6 of the carrier 2 is made more difficult by virtue of the fact that the cover foil 5 and the adjoining regions of the surface 6 of the carrier 2 are overprinted with an inteLco~ected ~aLL~L.l 14. That operation of printing the ~G~LeL~ 14 can also be effected in the continuous process already mentioned above, in a process step which occurs downstream of the operation of applying the cover foil 5.
It will be seen fram the foregoing that a value-bearing ~o~nt, for ~XA~1 e a value-bear m g paper 1 in accordance with the invention, arroL~s a large number of further options in regard to the provision of security features, in cu"~aLison with the previously known value-bearing ~oc~ ~ nts, but in that respect it is ~vcr always n~cPcs~ry to ensure that the cover foil 5 is h ~ ~aLe~lt at least in a region--. ~16~5~
wise "~eL, in the region of the at least one window-like opening 4 -it will be appreciated that a plurality of opPnin~s could also be provided - because it is only then that it is poss;hle to carry out a checking operation using the naked eye and it is only in such a case that an optical falsification effect occurs, upon an attempt at u~ction by means of color copying or printing, in the LL~ ~ale"l region within the opening 4. That fAlc;f;cAtion effect occurs in fact totally irrespective of which color is selected for the backyL~und in the copying operation, beca~l~e the COl~ e~onding region is not LLans~aLent in any case.
Figure 3 diagrammatically shows a lam m ation foil as can be used as the cover foil 5 for the value-bearing paper 1 in Figures 1 and 2.
That cover foil S in Figure 3 comerises a L~ ellt carrier filn 15. On its surface which is remote from the decorative layer 16, it is provided with a thin bonding or primer layer 17 which is intended to ensure that the pattern 14 which is A~Fl;P~ by printing adheres finmly to the carrier film 15. -The opposite surface of the carrier film 15 is also provided with abonding or pr imer layer 18 which is intended to ensure adequate A~ S;On of the decorative layer 16 on the r~rrier fi~m 15.
In the Gmh~d;mPnt shown in Figure 3 the decorative layer 16 -coLL~L.~ ;ng to the view shown in Figure 1 - is provided with diffeL~n~ security features 12, 13, both cases involving diffraction structures in accordance with the foregoing description.
For that purpose the decorative layer 16 ~as a ther-,~plastically deforT~ble base lAcquPr layer 19. Different diffraction structures 20 and 21 respectively are provided in that base lAcq~ler layer 19 in the regions cuLL~onding to the security features 12, 13, in which case the diffraction structures 20, 21 are pro~ce~ by suitable e~boss;ng of the ll~s~ lActically ~PfornAhle base 1AC~1~r layer 19 after the ~Appl;rAJtion thereof to the carrier film 15.
-- ~16~5~8 : 14 It will be appreciated that the diffraction structures 20, 21 are only visible at the cover foil 5 when the layers Pnclos;ng the diffraction structures 20, 21 have suitably different optical properties. For PxAmple, in the case of the diffraction structure 20 of the security feature 12, that is achieved in that a reflecting metal coating 22 is provided in the region of the diffraction structure 20;
the metal layer 22 may ~e for example an aluminium layer which is produced by vapor deposition in a vacuum or a layer, A~pl;P~ in a suitable manner, of another material which is known to be suitable.
Another possible way of rendering the diffraction structures 20, 21 visible provides that a suitable dielectric, for example TiO2 or TnS is Arpl;~ in the region of the diffraction structures 20, 21.
Then, in relation to the cover foil 5, the diffraction structure is covered over by means of a transparent protective lAcq~Pr layer 23 which in turn can carry a b~;ng or primer layer 24, at least in the region of the opening 4, in which ~ ec~ the bo~;ng or primer layer 24 has in par~ r t~e purpose of promoting A~hPs;on of the cover foil 5 to the surface 6 of the carrier 2. In addition however it may also favour a printing operation which is poss;hly to be s~bse~ Pntly effected - when de~Al;n~ with CO1Le~O~-1;ng1Y thin value-be æ ing ~oclrnPnts or in the case of l æ ge opPn;n~q - on the side of the cover foil, which is remote fL~" the surface 6 of the carrier 2, in the region of the opening or openings 4.
While the protective 1AC~lPr layer 23 is usually colorless - to fA~;l;tate identification of the security element - it can certainly ~e provided that, b~Ps;~es its diffraction effect, the second security feature 13 is dist;n~l;che~ by a par~ r coloring. In the case of the foil shown in Figure 3 for PXA~rle that is achieved by the diffraction structure 21 of the security feature 13 being covered with a ~ -Y~ t but colored l~c~)Pr layer 25 prior to the arpl;~tion of the p¢otective l~cquPr layer 23.
2163~
Mbre specifically a cover foil 5 as shown in Figure 3 could be of the following structure:
Bonding or primer layers 17, 18 and 24:
These layers are of a thickness of 0.2 to 2, ~lefeLably 0.5 to 1.2 S ~m. The bonding or primer layers 17 and 24 can possibly be omitted, more espe~iAlly in partictllAr when sllbse~)Ptlt overprinting of the cover foil is not envisaged.
The bonding or primer layers are ~rpl;P~ by a per se known printing process, in which respect they may be of the following composition:
Parts by weight Methyl ethyl ketone 400 Toluene 250 Cyclohexanone S0 Hydroxyl group-bearing vinyl chloride vinyl acetate terpolymer (Tg = 79CC, MW about 23,000) 210 Vinyl chloride vinyl acetate copolymer (MW about 4,000) 90 Carrier film 15:
This involves a suitable, optically clear, that is to say ~elLec~ly ~ s~2uent, film which should be as thin as poss;hlp in order not to stick up on the value-bearing paper, but on the other hand it must afford adequate strength. Polyester (PET) or pol~ccu~onate (PC) films of a thickness of between 6 and 12 ~m have been found to be suitable.
Thermoplastically defonmable base lacq~lPr layer 19:
This layer is of a thickness of usually 0.8 to 2 ~ , the thickness of the layer deF~;ng on the nature of the structure to be Arrl;P~
thereto, The base 1~C~Pr layer 19 is also Aprl;P~ by a printing ~Lucess and can be for Px~-~le of the following c~lL~s;tion:
2~63~2~
-Parts by weight Ethyl acetate 350 Toluene 200 Butyl acetate 130 Polymethyl methacrylate (softening point about 170C) 270 Styrene copolymer 5 (softening point about 100C) 50 Diffraction structures 20, 21:
These structures are known per se and are ~Tbocs~ into the base l~c~lPr layer 19 by means of suitable dies. The me~A~ Ation 22 comprises for example aluminium, chromium, gold or silver, Appl;e~ in a vacuum; depending on the material used pulverization can be effected by suitable ~Locesses, for example by vaporization, sputtering etc.
Instead of the metal layer it is also po~s;~le to apply a suitable dielectric, for example TiO2 or ZnS. Desirably, metAll;~Ation is Arrl;e~ over the entire, suitably shaped surface of the ~ Actic base 1ACqUPr layer 19 and then partially removed using a known ~L~cess.
There are different processPs in that respect, in which case in part;~-lAr those ~L~cesses are used in which, prior to the A~pl;~Ation of the metal layer, the structured surface of the ~ "~,~lActic base lac~Pr layer 19 is provided with a de~A~hAble layer in the unstructured regions, for ex_mple by printing in suitable register rela~io~h;r. After the metA~ Ation operation th_t det~rhA~lP layer is then removed again and thus the metA~ Ation is removed again in the region of the detA~hablP layer. The thickness of the me~All;7Ation or the dielectric layer is for ~XAmrle 60 to 20 A.
Transparent protective lacquer layer 23:
This layer is of a thickness of 1 to 5 ~m, ~L~L~Lably 2 to 3 ym, in which L~s~ec~ the thickness can be less in the regions where the additional lAcg~l~r layer 25 is provided than in the regions without an additional lacqupr layer of that kind. Moreover the thickness of the -- ~16352~
: 17 protective lacquer layer 23 ~ n~ on the L~ecLive ~P~.hAn;cAl requiL~,~nLs; in that Les~ecL, they are nornAlly not PxcPss;vely high becAllce on the one hand the size of the opening 4 is restricted and on the other hand the cover foil 5 is preferably A~pl;PA to the surface 6 of the carrier 2 in such a way that the decorative layer 16 faces towards the surface 6 of the carrier 2 so that the heavy mechanical loading occurs on the side of the carrier film 15.
The transparent protective lacqu~r layer can be for PxA~plP of the following c~T~os;tion:
Parts by weight Methyl ethyl ketone 300 Ethyl acetate 170 Cy~l ~h~xArlone 100 Hydrofunctional acrylate 15 (60% in Xylene/EPA, OH-number 140) 200 CP~ lose nitrate (low-viscosity, 65% in Alcohol) 80 Aromatic isocyanate (50% in ethyl acetate, NKC~content 8%) 150 The protective 1~ACqUPr layer 23 and possibly the additional lA~quer layer 25 are normally Arpl;P~ by a printing process, in which case the additional l~cquPr layer 25 is to be A~pl;PA by printing prior to the protective lAc9~1~r layer 23. In regard to the c~T~os;tion of the additional transparent lAcq~lPr layer 25, it is to be noted that this can be of substantially the same crT~.os;tion as the ~LuLe~Live 1AC9~l~r layer 23, but additionally contains a h ~ ~arent coloring agent.
In production of a value-be æ ing ~ex~Pnt, for example a value-be æ ing paper 1 in accordance with the invention therefore firstly the cover foil 5 is produced, for ~nple in a manner which is basically known from the production of hot S~AmP; ng foils, although the difference between the cover foil 5 and a hot stamping foil is that, in the case of the cover foil 5, care is taken to ensure that the dec~La~ive layer 16 adheres firmly to the c æ rier filn 15 while the -- ~16~52~
ess~nce of a hot stamp;~g foil is in fact precisely to be seen in the fact that the decorative layer can be eas;ly detached from the carri OE
fil~.
The cover foil is then Arpl;P~ to the carrier 2 of the value-bearing document, for example a value-bearing paper 1, preferably in a cont;nuouC rolling ~l~ce~re, in which case the window-like opPn;~g 4 is desirably produced in a first working operation, for e~Amrle by p~lnçh;ng. Subsequently or at the same time the carrier 2 is c~n~u~ssed to produce the depression 8, which can be effected for PXA~rlP by means of rollers, using suitably high pressures. Now, the cover foil 5 is A~p~ to the surface 6 of the carrier 2, by rolling. Fixing of the cover foil S on the carrier 2 can be effected by the protective l~c~)Pr layer 23 or the bonding or primer layer 24 of the decorative layer 16 of the cover foil 5 having suitable adhesive y~u~e~ies or by the decorative layer 16 of the cover foil 5 addit;onAlly being provided with a har~PnAhle adhesive layer (not shown). A further option is that, prior to the Appl;cation of the cover foil 5, the surface 6 of the carrier 2 is provided in the region of the depression 8 with an ~ppl;cAtion of adhesive, by means of which the cover foil 5 is then fixed to the carrier 2. Which of the two measures is adu~ed ~n~s on the nature or comFosition of the carrier 2, the decorative layer 16 of the cover foil 5 and the Le~kecLive purpose of use, in which .es~ecL it is also conceivable for adhesive to be p~ovided both on the cover foil 5 and also on the carrier 2.
After appl;cAtion of the cover foil 5 the surface 6 and poss;hly also the underside of the carrier 2 can then also be overprinted with the in~e~colmected ~aLLeL~I 14 by means of a conventional printing ~uocess for further ~nh~nc;ng the security aspect. Fin~lly when prc~lc~ng value-bearing papers the individual value-bearing papers are cut out of the paper cnmh;~e (web, sheets) fo~;n~ a rlllr~l;ty of carriers 2.
