Washable anti-counterfeiting hot stamping film and preparation method thereof

Abstract

The washable anti-counterfeiting hot stamping film comprises a base material layer, a release layer, an imaging layer, a metal reflecting layer and an adhesive layer which are arranged in sequence, a wear-resistant protective layer is arranged between the release layer and the imaging layer; a wear-resistant protective layer is arranged between the imaging layer and the release layer, and a buffer layer is arranged between the wear-resistant protective layer and the imaging layer, so that the wear-resistant protective layer has good wear-resistant, waterproof, weather-resistant and acid and alkali corrosion-resistant effects, and can protect the imaging layer; according to the anti-counterfeiting hot stamping film, the anti-counterfeiting layer is arranged on the anti-counterfeiting hot stamping film, so that the imaging layer can effectively express patterns in a longer time, the buffer layer has good elasticity and plays a role in blocking and buffering, and the phenomenon that the anti-counterfeiting hot stamping film is subjected to negative influence on the release effect and the wear-resisting effect of the finished anti-counterfeiting hot stamping film due to deformation damage of the anti-counterfeiting hot stamping film and the release layer in the imaging process is avoided; and the imaging effect of the finished hot stamping film can be improved.

Description

technical field [0001] The invention belongs to the technical field of hot stamping films, and in particular relates to a washable anti-counterfeiting hot stamping film and a preparation method thereof. Background technique [0002] Hot stamping film refers to the technology of combining laser holographic anodized aluminum film with hot stamping technology to form colorful laser holographic marks and anti-counterfeiting marks of three-dimensional patterns on the surface of printed matter. This technology can increase laser encryption and anti-tampering layer on the back. It is used for anti-counterfeiting of certificates, cards, bills, trademarks, etc. [0003] In the prior art, the general structure of the anti-counterfeiting hot stamping film is a base film layer, a release layer, an imaging layer, a metal reflection layer and an adhesive layer arranged in sequence, wherein the imaging layer is a layer for recording anti-counterfeiting information, and the imaging layer A...
