Abstract

A multifunctional decorative sheet with colors and rainbows relates to chromatic and rainbow decorations of the surface of an object. The utility model makes a layer of thin reflecting layer on a metal, plastics, a ceramic plate, a glass plate, a plexiglass plate or paper sheet and the layer of thin reflecting layer is also provided with character and pattern layer and a color showing layer with patterns of falcate shapes and bar shapes. The white light is enabled to generate various reflecting and interfering colors and rainbows having shapes on the surface of the object. The color is brilliant and changes with the viewing angle. The sunglasses of reflecting rainbow glass overlay film which are harmless to eyes enable others to see the rainbows on the glasses but the user can not see the rainbows. The multifunctional decorative sheet with colors and rainbows can be used for various decorations of trademarks, advertisements, exhibiting data, dials, sun films of cars, windowpanes, buttons, coats and caps.

Description

Decorative leaves with rainbow colour

The utility model relates to the multiple decoration of colour, rainbow of showpiece data, trade mark, advertisement, dial plate, sunglasses, car solar film, glass pane, button, clothing, cap.

Showpiece data, trade mark, advertisement, dial plate generally be utilize enlarge and print, duplicating, printing color method obtain colour or rainbow.Painted rainbow owes true to nature, also can not change change to some extent because of the visual angle.

In order to obtain aforementioned effect, decorate the decoration that has the single interference color of appearance under certain visual angle recently for the showpiece data.Pearl satin glass has also appearred in recent years.It can show rainbow according to grating diffraction principle of interference in the glass back when the light transmission grating.But it is difficult to make reflected white-light to show rainbow, thereby has limited its purposes at trade mark, dial plate etc.

The purpose of this utility model is that a kind of colour, decoration with rainbow colours will be provided, and it just can show multicolour or rainbow under the reflected white-light condition usually.And can change to some extent according to the variation at visual angle.

The purpose of this utility model is achieved in that utilizing white light to pass through film back reflection light and incident light produces the principle of interfering at film surface, on substrate, make the reflecting layer and increase the different step film of a layer thickness, because of the thickness difference, its interference color is just different.Thereby can realize the multicolour decoration; In addition, utilize the splitter film can make the principle of generating white light rainbow.On substrate, make the reflecting layer and make the figure film of gradient thickness thereon.Thereby realization decoration with rainbow colours.For the metal material substrate of easy oxidation or nitrogenize, can utilize the method for control oxidation or nitrogenize to make colour or iridescent film, its reflecting layer is exactly a substrate itself in this case; In addition, can also utilize control evaporation, spraying plating, plating, chemical plating, chemical deposition method to make the colour rainbow film, its thickness＜1 micron.

The utility model is owing to replace single homogeneous film with the step film of different-thickness, thus under the condition of same visual angle the while can show multicolour, and the latter is a solid color; Film with progressive thickness replaces grating in addition, can show rainbow under the reflected white-light condition usually, and the latter can show rainbow under the transmission condition, picture trade mark, dial plate, sunglasses, car solar film, button, clothing, cap, the utility model can show rainbow, and the latter is difficult to accomplish.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 to Fig. 4 is the profile according to the decoration with rainbow colours sheet that the utility model proposes.

Describe in detail according to the details of the multiple cosmetic sheet of colour rainbow that the utility model proposes and the reason of white light reflection variable color to closing Fig. 1 to Fig. 4 below.

Press Fig. 1 to shown in Figure 4, the multiple cosmetic sheet of colour rainbow comprises substrate (1), the reflecting layer on it (2), according to order character pattern (3) and color layer (4) is arranged then.

Substrate (1) can be transparent material and also can be opaque material, can be stainless steel substrates, steel disc, aluminum or aluminum alloy sheet, latten(-tin), plastic sheet, ceramics, sheet glass, lucite sheet or the scraps of paper.Make translucent or opaque film in on-chip reflecting layer (2).0 to 100 micron of thickness.When thickness be 0 be substrate replace this layer.Character pattern on the reflecting layer (3) is also made opaque or translucent vestige, also can be on color layer (4).In the reflecting layer or the unit section of the color layer above the character pattern (4) be splitter shape or bent moon, half bent moon, string, semifocal chord, step-like film.This film can be the oxide-film of substrate itself, and for example the oxide-film of stainless steel or brass also can be evaporation, spraying, plating or chemical deposition film, for example Zheng Fa SiO ₂The SnO of film, spraying ₂Film.

Reflecting layer (2) can be that substrate is as polishing aluminum or aluminum alloy, stainless steel, latten(-tin) itself.It also can be film.The used material of this film is chromium, copper, silver, gold, aluminium, tin, zinc, nickel, titanium etc.

When white light (5) reflexes to color layer (4) surface through color layer (4) and by reflecting layer (2), just press

L＝nλ

Show interference color (6), L is a thickness in the formula, and λ is certain color of light wavelength, n=0,1,2 ...As can be seen, the step film is because of the thickness difference from formula.Can under white light, show multicolour in same visual angle; In like manner, the film of progressive thickness can show rainbow.

By Figure 5 shows that colour rainbow decorative pattern signal plate.(7) to (9) are dial plate or button multicolour or rainbow style signal legend among the figure, and (10) to (14) are trade mark multicolour or rainbow style signal legend.(15) be sunglasses or car solar film, glass pane film rainbow style signal legend.

Claims

1, the multiple cosmetic sheet of a kind of colour rainbow, comprise substrate (1), the reflecting layer on it (2), according to order character pattern (3) and color layer (4) are arranged then, it is characterized in that substrate (1) can be transparent material and also can be opaque material, make translucent or opaque film in on-chip reflecting layer (2), character pattern on the reflecting layer (3) is also made opaque or translucent vestige, in the reflecting layer or the unit section of the color layer above the character pattern (4) be the splitter shape or be bent moon, half bent moon, string, semifocal chord, step-like film.
