[0027] For ease of understanding the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described below.

[0028] Embodiment

[0029] As Figure 1 and Figure 2 shown, a crystal label with a double-texture structure, the crystal label includes a base film 10, a transfer adhesive 20, an optical texture layer 30, an intermediate layer 40, a UV graphic layer 50, and a protective film 60 which are stacked. During the use of the crystal label, the base film 10 is separated, the transfer adhesive 20 is directly bonded to the product to be transferred, and finally the protective film 60 is separated, so that the double-texture structure of the crystal label is transferred to the product to be transferred. Here, the double-texture structure can be that both layers are icon structures, or one layer is an icon and the other layer is something else, or both layers are micro-nano structures; As Figure 2As shown, the base film 10 includes a first surface and a second surface opposite thereto. The base film 10 generally has a release film or a carrier with a release layer, such as release paper, etc.; a transfer adhesive 20, which is located on the first surface of the base film 10. The transfer adhesive 20 can be an adhesive or other glue that can be separated from the base film 10; an optical texture layer 30, which is located on the side of the transfer adhesive 20 away from the base film 10. The optical texture layer 30 includes a number of micro-nano texture units, and the micro-nano texture units are composed of a number of micro-nano texture structures 31. The material of the optical texture layer 30 is generally UV glue or other curable glue. The micro-nano texture structure 31 can be formed by imprinting, and can also be formed by printing or screen printing, and can also be formed by photolithography or laser direct writing. The micro-nano texture structure 31 faces the transfer adhesive 20, and there is a refractive index difference between the transfer adhesive 20 and the optical texture layer 30, and the refractive index difference is not less than 0.2. In this way, the effect of the micro-nano texture structure 31 will not disappear due to the transfer adhesive 20. Therefore, when the two are in direct contact, there needs to be a refractive index difference between them to ensure that the effect of the micro-nano texture structure 31 can be perfectly presented; an intermediate layer 40, which is located on the side of the optical texture layer 30 away from the transfer adhesive 20. The intermediate layer 40 is formed of an optical material and has a certain transmittance; a UV graphic layer 50, which is located on the side of the intermediate layer 40 away from the optical texture layer 30. The UV graphic layer 50 includes a number of UV graphic structures 51, and the UV graphic structures 51 can be completed by a UV printing device. Further, it also includes a protective film 60, which is located on the surface of the UV graphic layer 50 and covers the UV graphic layer 50.

[0030] There are certain requirements for the matching settings between multiple layers. For example, the adhesion between the base film and the transfer adhesive should be less than the adhesion between other laminated structures. After the base film is torn off, the transfer adhesive will adhere to the item to be transferred. The adhesion between the protective film and the UV graphic layer 50 should be less than the adhesion between other laminated structures, including the adhesion between the transfer adhesive and the item to be transferred. Only in this way will the crystal label not be damaged when tearing off the base film and the protective film during use.

[0031] In this way, the crystal label provided by this application has a double texture structure, thus forming an optical illusion crystal label with a micro-nano texture layer and a graphic structure after UV printing. The micro-nano structure image is a technology based on micro-nano structures or micro-nano structure physical color display, with characteristics such as dynamic light and shadow changes, naked-eye stereoscopy, light-changing color, and multiple optical anti-counterfeiting features.

[0032] Such as Figure 2 And Figure 3As shown, the difference between the two structures lies in the different optical texture layers 30, such as Figure 2 As shown, the micro-nano texture structure 31 on the surface of the optical texture layer 30 is a microlens structure. The microlens structure can form a light and shadow effect, or can form an effect with icons, graphics and texts. The microlens is a convex structure, and of course it can also be a concave structure; such as Figure 3 As shown, the micro-nano texture structure 32 on the surface of the optical texture layer 30 is a holographic structure. The holographic structure can form a light and shadow effect, or can form an effect with icons, graphics and texts, and can also form graphics and icons with colors. It can be seen from the figure that the holographic structure is formed by convex and concave structures, such as Figure 5c As shown, it is a three-dimensional scan diagram of the holographic structure, and the three-dimensional morphology of the holographic structure can be seen; further, the micro-nano texture structure can also be one or more combinations of a cylindrical lens, CD pattern, Fresnel lens, wire drawing pattern, etc.

[0033] Further, such as Figure 4 As shown, another structure of the crystal label is given. A reflective layer 70 is provided between the optical texture layer 30 and the transfer adhesive 20. The reflective layer 70 is a single-layer structure or a multi-layer structure; the reflective layer 70 can be formed by coating. When the reflective layer 70 is provided on the surface of the optical texture layer 30, whether there is a refractive index difference between the transfer adhesive 20 and the optical texture layer 30 is no longer important. The two can have the same refractive index. Because the reflective layer 70 is provided in the middle, the transfer adhesive 20 will not affect the micro-nano texture structure.

[0034] Further, such as Figure 5a As well as shown in 5b, the micro-nano texture units are periodically arranged on the surface of the optical texture layer, Figure 5a It can be seen that the shape of the micro-nano texture unit is square, Figure 5b The shape of the micro-nano texture unit is circular, arranged periodically, and the micro-nano texture structures in each micro-nano texture unit can be different; the shape of the micro-nano texture unit can be a polygon shape such as a triangle, quadrilateral, pentagon, etc., and can also be a shape such as a circle, ellipse, etc. Further, there are at least two different micro-nano texture structures in the micro-nano texture units. Here, the different micro-nano texture structures can be different parameters such as the size and period of the micro-nano texture structure. Therefore, the micro-nano texture units constituting the optical texture layer can display the optical effects formed by the micro-nano texture structures, and this effect will be superimposed with the effect of the UV graphic structure. Such a crystal label will have a double dazzling effect, and this design combination is diverse, which can well enrich the styles of crystal labels.

[0035] Such as Figures 6a - 6b As well as Figures 7a - 7b, mainly gives the illustrations of using crystal labels on products, which can be electronic products, labels, daily necessities, etc. Figures 6a - 6b As shown, a transfer product includes an article to be transferred 100, wherein the article to be transferred 100 includes a first surface and a second surface arranged opposite to the first surface; a transfer adhesive 20, wherein the transfer adhesive 20 is attached to the first surface of the article to be transferred 100; an optical texture layer 30, wherein the optical texture layer 30 is located on a side of the transfer adhesive 20 away from the article to be transferred 100, wherein the optical texture layer 30 includes a plurality of micro-nano texture units, wherein the micro-nano texture units include a plurality of micro-nano texture structures 31; an intermediate layer 40, wherein the intermediate layer 40 is located on a side of the optical texture layer 30 away from the transfer adhesive 20; and a UV graphic layer, wherein the UV graphic layer is located on a side of the intermediate layer 40 away from the optical texture layer 30, wherein the UV graphic layer includes a plurality of UV graphic structures 51. Figure 6a , 6b It can be seen that the crystal label is AB, the UV graphic structure 51 is A and B, and when the crystal label is attached to the transfer object 100, the optical texture layer 30 is a continuous structure, that is, there is still an optical texture layer 30 between A and B. Figure 7a , 7b As shown, Figure 6a , Figure 6b Different, the same crystal label AB, the UV graphic structure 51 is A and B, and when the crystal label is attached to the transfer product 100, the optical texture layer 30 is a discontinuous structure, that is, there is still no optical texture layer 30 between A and B, or the optical texture layer 30 also forms A and B, and overlaps with A and B of the UV graphic structure 51. Although the optical texture layer 30 forms A and B, A and B of the optical texture layer 30 are composed of a micro-nano texture structure 32.

[0036] After the double-layer texture structure provided by the present application is combined with UV printing with or without positioning, the image composed of the optical effect matches the ink printing pattern. Under the dual effects of light and ink, the pattern is more vivid and colorful, giving it a unique luster and texture that cannot be achieved by ordinary printed crystal labels; both from the technical level of the production process and the aesthetics of the decorative pattern, it is a perfect improvement over ordinary printed crystal labels.
