Problems solved by technology

[0007] The existing anti-counterfeiting type materials are required to have low elongation, chemical resistance Good performance, no co-solvent, good film-forming performance, fast drying speed, high production efficiency, etc. In order to meet the above requirements, many companies have developed a variety of dielectric film compositions, one is acrylic resin, and the other is cellulose. , the former resin composition is easy to damage the ink, making the anti-counterfeiting effect poor, and the latter resin composition is prone to burrs or non-dropping characters, so that the anti-counterfeiting effect cannot be achieved
Moreover, the composition of the existing dielectric film layer all contains a strong polar co-solvent, which is corrosive to the ink, so that the effect of the font displayed when the anti-counterfeit font material is uncovered is not good, and the ink is easy to fall off, and the font is not good. Clear, which brings inconvenience to users, but also increases the difficulty for users to verify the anti-counterfeiting effect of products

Abstract

The invention provides a resin composition for an anti-counterfeiting matrix material dielectric film and an anti-counterfeiting matrix material. The anti-counterfeiting matrix material sequentially comprises a surface material, a pattern layer, a protective layer, an ink layer, a dielectric film, an adhesive layer and release paper, wherein the dielectric film is formed from the resin composition; and the resin composition comprises the following components in parts by weight: 50-90 parts of water-based polymer emulsion, 5-15 parts of solvent, 0-5 parts of assistant and 0-5 parts of filler. Compared with the prior art, the dielectric film resin composition adopts the water-based polymer emulsion without any cosolvent, and thus, has no corrosivity for the ink; and the functional group of the water-based polymer emulsion is beneficial to flow and wettability of molecular chains on the ink surface, so that the formed dielectric film has favorable adhesive force with the ink layer, and has higher surface energy to be well bonded with the adhesive.

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 medium film layer of an 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 mark...
