Abstract

The invention belongs to the technical field of package anti-counterfeiting, and relates to a preparation method of a holographic laser hot stamping film, in particular to a preparation method of a corrosion-resistant and friction-resistant holographic laser hot stamping film. The corrosion-resistant and friction-resistant holographic laser hot stamping film is characterized by sequentially comprising a base layer, a stripping layer, a color layer, an electroplated layer and a glue layer from bottom to top, wherein the base layer comprises the following components in parts by weight: 50-70 parts of modified acrylic resin, 30-40 parts of a polyurethane film and 5-13 parts of a covalent organic framework material. According to the preparation method of the corrosion-resistant and friction-resistant holographic laser hot stamping film provided by the invention, the prepared holographic laser hot stamping film has the advantages of wear resistance, acid and alkali corrosion resistance andlong service life, meanwhile, the brightness and the anti-counterfeiting strength of the color layer, containing holographic information patterns, of the hot stamping film in a high-temperature hot stamping process are guaranteed, the production is simple, and the construction is convenient.

Description

technical field [0001] The invention belongs to the technical field of packaging anti-counterfeiting, relates to a preparation method of a holographic anti-counterfeiting hot stamping film, and more specifically relates to a preparation method of a corrosion-resistant and friction-resistant holographic laser hot stamping film. 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 add laser encryption and anti-tampering layer on the back, which is used for anti-counterfeiting of documents, cards, bills, trademarks, etc. If this kind of anti-counterfeiting mark is added on the outer packaging of the product, its anti-counterfeiting strength is unmatched by the current single laser holographic anti-counterfeiting mark. In ad...
