Description
1 Aqueous Ink Composition for Writing Instrument BACKGROUND OF THE INVENTION
Field of the Invention The present invention relates to an aqueous ink composition for writing instrument, and more particularly to aqueous ink adapted for use in a ball point pen.
Related Background Art Conventional ball point pens are generally classified into oil ball point pens utilizing highly viscous oily ink and aqueous ball point pens utilizing aqueous ink of low viscosity, but highly viscous aqueous ink is recently proposed for the aqueous ball point pens.
Such highly viscous aqeuous ink maintains a high viscosity under a weak shearing force, but exhibits a low viscosity under a high shearing force, as generated by the rotation of the ball in the writing operation of the ball point pen.
As examples of the above-mentioned proposal, the Japanese Patent Publication No. 64-8673 discloses the use of xanthane gum, and the Japanese Patent Laid-open Application No. 4-214782 discloses the use of wellan gum, for increasing the viscosity of aqueous ink.
However, it is difficult, in such gum-containing _ - 2 210561~
1 aqueous ink, to maintain long-term stability of dispersion of the pigment constituting the coloring material, and the ball point pen employing such-ink may result, in the writing after a prolonged time, in a pale or excessively dense record, and may eventually become incapable of writing operation due to the ink blocking at the pen tip by pigment coagulation.
SUMMARY OF THE INVENTION
The present invention is to provide aqueous ink of high viscosity, which is free from detrimental influence on the dispersed or dissolved stage of the coloring material even after a prolonged time.
The present invention is to provide an aqueous ink composition for writing instrument, containing as essential components (1) a coloring material, (2) an organic acid-modified heteropolysaccharide of an average molecular weight of about 1 million to 8 million (hereinafter called succinoglycan) consisting of a basic unit composed of glucose/galactose/pyruvic acid or salt thereof/succinic acid or salt thereof/
acetic acid with a molar ratio of 5 - 8/1 - 2/0.5 -2/0.5 - 2/0.5 - 1, and (3) aqueous medium containing water and water-soluble organic solvent, in which water constitutes at least 50 % by weight.
The above-mentioned succinoglycan has a skeletal structure of a heteropolysaccharide composed , 1 of glucose and galactose of the above-mentioned moler ratio and having a side chain, in which pyruvic acid is ketal bonded to the carbon atoms at 4 and 6 positions of monosaccharide at the end of said side chain, and one of carboxyl radicals of acetic acid and succinic acid is ester bonded to the free hydroxyl radical of the monosaccharide constituent, wherein the free carboxyl radical ofpyruvicacid and succinic acid may be present as sodium, potassium or calcium salt. Such succinoglycan is employed in an amount of 0.01 to 8 wt.%, preferably 0.1 to 4 wt.% in the ink composition.
The coloring material can be pigments or dyes ordinarily employed in the aqueous ink.
Examples ofthe pigment include inorganic pigments such as carbon black or iron oxide, and organic pigments such as azo pigments, anthraquinone pigments, condensed polyazo pigments, thioindigo pigments, metal complex pigments phthalocyanine pigments, perynone/perylene pigments, dioxadine pigments and quinacr~done pigments.
Examples of the dye include acid dyes such as eosine (C.I. 45380), acid floxide (C.I. 45410), erythrosine (C.I. 45430), tartrazine (C.I. 19140), sunset yellow FCF (C.I. 15985), acid rhodamine (C.I.
45100), acid violet 6B (C.I. 42640), brilliant blue FCF (C.I. 42090), water black R510 (C.I. 50420)* etc., direct dyes such as direct fast yellow GC (C.I. 29000), *trade-mark of Orient Chemical Industries Co., Ltd.
210a61~
1 violet BB (C. I. 27905), direct sky blue 5B (C. I. 24400), black G (C.I. 135255) etc., and basic dyes such as rhodamine B (C. I. 45170), rhodamine 6GDN (C.I. 45160), methyl violet (C.I. 42535), victorial blue BOH (C. I.
42595) etc. Such coloring material is employed in an amount of 1 to 25 % by weight, preferably 2 to 15 %
by weight, in the ink composition.
The aqueous medium contains water and water-soluble organic solvent, in which water constitutes at least 50 % by weight.
Said water-soluble organic solvent can be, for example, ethylene glycol, diethylene glycol, propylene glycol, thiodiethylene glycol, glycerine or triethanol-amine, suitably selected for the purpose of suppressing the ink drying at the pen tip, providing the written record with water resistant property, or as a co-solvent for the dye, and is employed in an amount of 5 to 30 % by weight in the ink composition.
The aqueous medium may additionally contain, if necessary, various surfactants for improving the ink fluidity or stabilizing pigment dispersion, a water-soluble resin such as polyvinylpyrrodidone, polyvinyl alcohol, water-soluble acrylic resin or gum arabic for preventing the blotting of written record or as protective colloid for the pigment, lubricant, moisture retaining agent, antiseptic and antirusting agent.

l The aqueous ink of the above-explained compo-sition is present as gel and exhibits fluidity by vigorous agitation. Consequently it is adapted for use in a ball point pen of a structure similar to that of the oil ball point pen employing highly viscous oil ink, namely a simple structure consisting of a pen tip not involving additional members such as the ink absorbent member, valve structure and regulator (a regulating member for temporarily storing the ink supplied in excess from the ink absorbent member and regulating the replacement with air), and a pipe member serving as ink reservoir.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
15 Ink samplesof examples 1 - 6 and reference examples 1 - 4 were prepared and subjected to the measurement of the particle size of the dispersed pigment, immediately after the preparation (initial) and after 2 months. Also each sample was filled in a ball point pen of a structure similar to that of said oil ball point pen, and subjected to writing tests immediately after preparation and after the pen was let to stand for 2 months with the pen tip downwards.
The particle size of the dispersed pigment was measured by the light transmission method, based on the liquid phase sedimentation.
The ink sample was prepared by gradually adding - - 210561~
1 succinoglycan (xanthane gum or wellan gum in case of reference exmaples) into a predetermined amount of water under agitation, then, after uniform dissolution, charging the coloring material, water-soluble organic solvent and other additives and uniformly dissolving or dispersing these components.
Tables 1 and 2 show the compositions and test results of the inks of, respectively, the examples and the reference examples.
The compositions in said tables are all repre-sented by parts by weight. The components numbered in the tables are explained in the following:
(1) aqueous pigment dispersion consisting of 15 wt.% of carbon black, 4 wt.% of polyvinyl alcohol and the remainder by water;
(2) aqueous pigment dispersion consisting of 14 wt.% of quinacridone red E (C.I. pigment red 209), 12 wt.% of polyvinyl alcohol and the remainder by water;
