Embodiment Construction

[0017] The manufacturing process of the anti-counterfeit microstructure pigment of the present invention first adopts the deposition technology to make an optical thin film on the substrate, and then uses the microstructure technology to make a metal template with a micro-graphic concave-convex groove structure. Through the stamping of the metal template on the optical film, the sheet-shaped optical film is stamped into fragments with a microstructure on the surface of the metal template, and finally the specific shape of the microstructure is peeled off from the substrate to become a microscopic pigment with optical anti-counterfeiting function . The anti-counterfeiting pigment of the present invention can be designed to have specific and recognizable geometric shapes, text patterns, etc., and the surface of the pigment particles can also carry specific text and pattern information, which has an optical anti-counterfeiting effect. Anti-counterfeiting pigments of different sha...

Abstract

The invention relates to an anti-counterfeiting microstructure pigment and a manufacturing process thereof. The anti-counterfeiting microstructure pigment is an identifiable optical anti-counterfeiting pigment made of an optical membrane and has a specific shape and pattern. The process comprises: step A, selecting a peelable substrate with a smooth surface, and coating the peelable substrate uniformly with a stripping glue-line that is mouldable through compression; step B, depositing the optical membrane on the surface of the stripping glue-line; step C, manufacturing a metal matrix with a microstructure pattern; step D, conducting compression on the optical membrane with the metal matrix with a microstructure pattern, and making the same microstructure pattern of the metal matrix formed on the compressed optical membrane, with the depth of a concavo-convex groove of the pattern on the metal matrix greater than the thickness of the optical membrane, so that the optical membrane can be compressed and split into fine pattern platy grains similar to the microstructure pattern, and leaving the fine pattern platy grains sticked on the plastic substrate by the stripping glue; step E, peeling the optical membrane platy grains off the substrate, thus forming the anti-counterfeiting pigment.

Description

technical field [0001] The invention relates to an anti-counterfeiting material and a manufacturing process thereof. Background technique [0002] The application of anti-counterfeiting technology in various industries can help consumers quickly identify the authenticity of goods and protect consumer rights and interests. At the same time, it can help business users fight against counterfeit products, eliminate batch anti-manufacturing, protect corporate brands, maintain corporate image, and avoid economic losses. The anti-counterfeiting technologies usually used in the field of packaging are mainly as follows: precision printing, laser holographic printing, metal wire, fluorescent dyes, magnetic dyes, thermal dyes, microprinting, steel mold pressing, etc. These technologies have all played a certain role in the initial stage of use, but these anti-counterfeiting technologies generally have defects such as low technical content and easy deciphering of structural combinations...
