Abstract

The invention relates to a manufacturing method for magnetic anti-fake miniature particles. The manufacturing method comprises the following steps of coating a substrate by using a stripping glue layer which can be formed in a mould pressing manner; depositing an optical film on the surface of the stripping glue layer; coating the surface of the optical film by using a magnetic material layer; manufacturing a template with micro-structure graphs; stamping the substrate by using the template with the micro-structure graphs so that the magnetic material layer and the optical film on the substrate are pressed to be cracked into magnetic anti-fake miniature particles which are the same with the micro-structure graphs; adhering the particles to the substrate by using the stripping glue layer; and stripping off the magnetic anti-fake miniature particles from the substrate. Compared with the prior art, the manufacturing method for the magnetic anti-fake miniature particles has the advantages that a metal template stamping process is adopted, so that the magnetic anti-fake miniature particles can be manufactured in batches; and the magnetic anti-fake miniature particles can be widely applied, and can be directly added in a base material, or by adding the magnetic anti-fake miniature particles in printing oil or coating, the printing oil or coating is printed on a packaging material and has an anti-fake effect.

Description

technical field [0001] The invention relates to an anti-counterfeiting material and a preparation method thereof, in particular to a method for manufacturing magnetic anti-counterfeiting micro particles. 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 hav...
