[0004] But the layer structure of the above scheme plays an anti -fake role only in nano coating setting specific pattern to form printing layer, and the anti -fake structure is single, which is easy to be imitated, because the technology uses ink similar in chemical composition to printing layer to print, to realize errorless overprint.However, this approximation may also make it easier for the copier to find similar ink for imitation, thereby reducing the anti -fake effect, and when the printing layer falls off or is scratched, the anti -fake effect of the technology will be further reduced.

[0005] Based on this, a kind of holographic anti -fake laser film is presented. INVENTION CONTENTS

[0019] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined purposes, the specific embodiments, structures, features and effects of the present application will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0020] Please refer to Figure 1The embodiment provides a holographic anti-fake laser film, which comprises, from bottom to top, a substrate layer 1, a printing layer 2, an aluminum plating layer 3 and a transparent scratch-resistant layer 4, and further comprises an anti-fake information block 5, the transparent scratch-resistant layer 4 is arranged on the upper surface of the aluminum plating layer 3, and the anti-fake information block 5 is embedded in the substrate layer 1, the anti-fake information block 5 is provided with anti-fake information, the aluminum plating layer 3 arranged on the printing layer 2 can enhance the adhesion of ink on the printing layer 2 of the film, so that the ink is not easy to fall off during the printing process, and the quality of the printed matter is improved. Meanwhile, the aluminum plating layer 3 also has good adhesion and can be firmly attached to the surface of the substrate and is not easy to peel off, and the aluminum plating film has the characteristics of high reflectivity, can effectively reflect light, and makes the product more bright and dazzling under light, and can improve the beauty of the laser film.

[0021] The anti-fake information arranged on the anti-fake information block 5 is mainly made on the surface or inside of the film by laser holographic technology and has unique optical effects and anti-fake functions. The anti-fake layer utilizes the holographic imaging and optical interference principle of laser to form images or patterns with three-dimensional sense, which are not only beautiful but also difficult to copy, so that the anti-fake function of the product is realized. The anti-fake layer is usually customized when the laser film is produced, so that the laser film product has unique properties to distinguish from other laser film products, and the laser film product is not easy to be copied.

[0022] The transparent scratch-resistant layer 4 is an elastic resin scratch-resistant film, the transparent wear-resistant layer is arranged on the upper surface of the aluminum plating layer 3 and the edges of the transparent wear-resistant layer extend to the edges of the substrate layer 1 and overlap the edges of the substrate layer 1, that is, the transparent wear-resistant layer and the substrate layer 1 wrap all the layer structures between them, so as to isolate harmful substances such as oxygen and moisture in the air, slow down or prevent the oxidation reaction on the surface of the material to prolong the service life of the laser film product. Since the transparent scratch-resistant layer 4 is located at the outermost side of the layer structure, it is most likely to be contacted. If it has no elasticity or small elasticity, the friction generated during the taking process will cause cracking at some positions, and the transparent scratch-resistant layer 4 will be broken after being contacted with hard objects such as nails. Therefore, the transparent scratch-resistant layer 4 has a certain elasticity, can ensure that it has a certain ductility and repairability, can have a certain deformation when encountering pulling force, and can avoid breaking. After being contacted with hard objects, it can produce certain shrinkage deformation and is not easy to break, thereby prolonging its service life.

[0023] Further, in order to improve the anti-counterfeiting of the product, a grating layer 6 is arranged between the aluminum plating layer 3 and the transparent scratch-resistant layer 4, and the grating layer 6 is provided with light refraction blocks with different refraction angles. The light refraction blocks are lines or grooves, which can cause the incident light to diffract, that is, when the light wave encounters the grating, it will bend and disperse according to the periodical structure of the grating, forming a specific diffraction pattern, so that the product can diffract different patterns, increasing the anti-counterfeiting. Correspondingly, the transparent scratch-resistant layer arranged on the upper surface of the grating layer 6 is provided with a plurality of display areas corresponding to the areas of the light refraction blocks, and the plurality of light layers are displayed through the plurality of display areas, so that the light refracted by the light refraction blocks of the grating layer 6 can be well transmitted.

[0024] Further, in order to reduce the accumulation of dust on the surface of the transparent scratch-resistant layer 4, affecting the light transmittance and aesthetics of the laser film, and because static electricity can attract and adhere to dust and other small particles, an antistatic layer 7 is further included. The antistatic layer 7 is arranged on the lower surface of the transparent scratch-resistant layer 4, which can effectively reduce the dust adsorption phenomenon caused by static electricity on the surface of the protective film. When the antistatic layer 7 works, it can neutralize or eliminate the static electricity below the protective film, thereby reducing the risk of dust adsorption. The antistatic layer 7 also includes an antistatic layer 7, which works by forming a conductive layer on the surface of the material, thereby reducing its surface resistivity and allowing the static charge to leak quickly. Because the accumulation of electric charge can attract dust in the air to accumulate on the surface of the film, the accumulated dust can affect the light transmittance of the laser film, thereby affecting the use effect of the laser film.

[0025] Further, a plurality of anti-reflection strips 8 are further included, which are uniformly embedded in the antistatic layer 7, and the thickness of the plurality of anti-reflection strips 8 is less than that of the antistatic layer 7, which can reduce the situation that light is reflected back before entering the film, thereby improving the utilization efficiency of light for improving the overall light transmittance of the laser film. The anti-reflection strip 8 is made of a coating material with anti-reflection function, which can protect the laser layer while ensuring that the optical performance of the laser layer is not affected.

[0026] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above-mentioned equivalent embodiments without departing from the technical solution of the present application. Any modification, equivalent change and modification of the above-mentioned embodiments, which does not deviate from the technical solution of the present application, is still within the scope of the present application.
