Optically variable image anti-counterfeiting printing pet film

Abstract

The invention discloses an optically variable image anti-fake printing PET (polyester) film. The optically variable image anti-fake printing PET film is characterized by comprising a composite layer structure which comprises a spherical wear-resistant resin protective layer, an optically variable image information layer, a PET supporting layer and a printing adhesive layer from top to bottom in sequence; the optically variable image information layer is a light-cured resin layer, and a raster image is molded on the light-cured resin layer. The optically variable image anti-fake printing PET film has the beneficial effects as follows: the film integrates the characteristics of carrying full-range optically variable image anti-fake information and realizing personalized laser printing, has obvious anti-fake characteristics, is easy to identify, can effectively solve the problem that personalized information is falsified, and can meet requirements for fast certificate making; the PET film disclosed by the invention is stable in physical and chemical properties, good in tensile strength, strong in adaptability, temperature-resistant and pressure-resistant in raster structure and long in quality guarantee period; by using the PET film disclosed by the invention to make certificates, the certificates are strong in integrity, good in consistency, strong in stripping resistance, bending resistance, aging resistance and damage resistance and good in durability, and are difficult to counterfeit.

Description

technical field [0001] The invention relates to a PET film, in particular to an optically variable image anti-counterfeiting printed PET composite film. Background technique [0002] The national statutory certificate is a carrier composed of various functional materials and has exclusive identification information. The various functions of the certificate are realized by technical means of loading and recording information on the material. After nearly five years of rapid development , has made breakthroughs both at home and abroad, especially with the development of card-type government projects such as ID cards, people's police cards, and Hong Kong and Macau passports. Personalized materials for documents have obtained a good development platform, but they can meet the requirements of legal documents. There are almost no personalized printing materials with high-strength anti-counterfeiting capabilities required by durability, damage resistance, and weather resistance. E...

AI Technical Summary

Problems solved by technology

Even if there are similar products, either the adhesion requirements between the printing film and the card body cannot be solved, or the damage resistance and durability of the anti-counterfeiting information layer cannot be solved.
