Problems solved by technology

The protective layer needs to have high hardness and chemical resistance. In order to meet the above requirements, many companies have developed a variety of protective layer compositions: one is the reaction between the resin composition and the curing agent. This protective layer composition can not only be used in It can react quickly at a lower temperature, and it can also react automatically at room temperature. When coating the protective layer, it can be rolled up after passing through the drying tunnel and only when the surface is dry, and then it can be cured at room temperature. effect, but the raw material resin composition of this method is mostly imported raw materials, and the cost is high; the other is the composition in the main resin according to the ratio of the amino resin, because the crosslinking of the amino group can only react quickly at high temperature, and the work Low efficiency and high cost

Abstract

The invention provides a resin composition for an anti-counterfeit matrix material protective layer and an anti-counterfeit matrix material. The anti-counterfeit matrix material comprises a surface material, a pattern layer, a protective layer, an ink layer, a dielectric layer, an adhesive layer and release paper in sequence, wherein the protective layer is formed by curing the resin composition with an isocyanate curing agent. Compared with the prior art, the resin composition and the anti-counterfeit matrix material have the beneficial effects that the protective layer takes acrylic resin as the main film forming material and the acrylic resin has better physical and mechanical properties, excellent weather resistance, chemical resistance and water resistance and high light and colour retention and has better protective effects on the pattern layer; meanwhile, the cellulose ester resin is added as an additive accelerator; the hydroxyl of the cellulse ester resin and the isocyanate curing undergo an addition polymerization reaction and then a film is formed by curing, so that the resin composition can form the film quickly; and besides, the cellulose ester resin has better hydrophilicity and lipophilicity and can endow the protective layer with better printing adaptability.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeit materials, and in particular relates to a resin composition for a protective layer of anti-counterfeit type material and an anti-counterfeit type material. Background technique [0002] Counterfeiting has existed since ancient times, so anti-counterfeiting is an ancient topic, as old as human civilization. With the increasing prosperity of the commodity economy and the continuous development of science and technology, anti-counterfeiting has become a new and constantly changing field. [0003] Anti-counterfeiting technology refers to the measures taken to achieve the purpose of anti-counterfeiting. It can accurately identify the authenticity within a certain range and is not easy to be imitated and copied. Simply put, it is a technology to prevent counterfeiting and counterfeiting. It is a preventive technical measure adopted in order to protect the corporate brand, protect the market, ...
