Problems solved by technology

However, most of the current colorful color-changing films are transparent, and their surface color is relatively light. In addition, the multi-colored color-changing films mostly use a technology to present the color-changing effect, which is less difficult to imitate and greatly reduces the anti-counterfeiting effect of the product.

[0036] Such as figure 1 As shown, the multicolor color-changing film provided in this embodiment includes a base film layer 1 , an information layer 8 , a first film layer 2 , an organic layer 3 , a second film layer 4 and a color layer 5 from top to bottom. The surface of the information layer 8 having the micro-nano structure 81 is in contact with the first film layer 2 .

[0037] The base film layer 1 adopts a biaxially stretched polyester film with a thickness of 25um; the material of the first film layer is zinc sulfide, which is produced by vacuum evaporation, and the thickness is 100nm; the material of the organic layer 3 is PMMA (Polymethyl methacrylate, polymethyl methacrylate). methyl acrylate) resin, made by nano-coating process, with a thickness of 100nm; the material of the second film layer 4 is zinc sulfide, made by vacuum evaporation, with a thickness of 100nm; the number of color layers is 1, and the number of color layers The color is black, made by nano-coa...

[0043] Such as Figure 4 As shown, the difference between the colorful color-changing film provided in this embodiment and the above-mentioned first embodiment is that in this embodiment, the color layer 5 includes three color regions, wherein the color layer 5 includes a first color region 51, a second color region 51, and a second color region respectively. The area 52 and the third color area 53 have different colors in different color areas.

[0044] In this embodiment, the color areas are distributed according to the hollowed-out design of the product pattern. The first color area 51 is black, the second color area 52 is dark purple, and the third color area 53 is dark blue, and the distribution of the color areas corresponds to the desired pattern.

[0045] Such as Figure 5 As shown, the hollow part of the color layer 5 can also achieve the effect of changing the color with the change of the viewing angle due to the slab waveguide resonance structure composed of the fi...

[0047] Such as Image 6 As shown, the difference between the colorful color-changing film provided in this embodiment and the above-mentioned first embodiment is that, in this embodiment, a release layer 6 and a hot-melt adhesive layer 7 are added to the colorful color-changing film.

[0048] Specifically, the release layer 6 is fixedly laid on the lower surface of the base film layer 1; the information layer 8 is arranged on the lower surface of the release layer 6, and the surface of the information layer with the micro-nano structure 81 is in contact with the first film layer 2 ; The hot melt adhesive layer 7 is fixedly laid on the lower surface of the color layer 5 .

[0049] The release layer 6 is used to facilitate peeling off the base film 1 after hot stamping. Therefore, the release layer 6 after peeling off the base film 1 can be in the outermost layer of the whole colorful color-changing film, and has the effect of protecting the first medium layer 2; certainly, whe...

Abstract

The invention discloses a colorful color-changing film which comprises a base film layer, a first film layer arranged on the surface of one side of the base film layer, an organic layer arranged on the surface of one side, far away from the base film layer, of the first film layer, a second film layer arranged on the surface of one side, far away from the first film layer, of the organic layer, and a color layer is arranged on the surface of the side, away from the organic layer, of the second film layer, and the first film layer, the organic layer and the second film layer form a slab waveguide resonance structure. Through the structure, the color presented by the first film layer, the organic layer and the second transparent medium originally is changed, so that the colorful color-changing film has a richer and more complex color-changing effect; and meanwhile, the anti-counterfeiting effect of the colorful color-changing film is enhanced through superposition, and the anti-counterfeiting property of the product is greatly improved.

Description

technical field [0001] The invention relates to the technical field of color-changing films, in particular to a colorful color-changing film. Background technique [0002] Existing colorful color-changing film is bright color, and color is multicolored. However, most of the current colorful color-changing films are transparent, and their surface color is relatively light. In addition, the multi-colored color-changing films mostly use one technology to present the color-changing effect, which is less difficult to imitate and greatly reduces the anti-counterfeiting effect of the product. [0003] The foregoing description is provided to provide general background information and does not necessarily constitute prior art. Contents of the invention [0004] The purpose of the present invention is to provide a multi-color color-changing film with high anti-counterfeiting degree, which has a strong color-changing effect when the viewing angle changes. [0005] The present inve...
