Abstract

The invention relates to a preparation method for a microstructure particle with interference fringes. The method comprises the following steps: coating a substrate with a strippable adhesive layer which can be formed through compression molding; depositing an optical thin film on the surface of the strippable adhesive layer; coating the surface of the optical thin film with a plastic layer; molding the plastic layer so as to allow the plastic layer to generate interference fringes; making a template with a microstructure pattern; stamping the substrate by using the template with the microstructure pattern so as to allow the plastic layer and the optical thin film on the substrate to be compacted and fracture, thereby forming the microstructure particle identical to the microstructure pattern, wherein the particle is adhered on the substrate through the strippable adhesive layer; and stripping off the microstructure particle from the substrate. Compared with the prior art, the preparation method provided by the invention can realize large scale manufacturing of the microstructure particle through adoption of a metal template stamping process; the microstructure particle has a wider application scope and can be directly added into the substrate or be printed on a packaging material for anti-counterfeit after addition of the particle into printing ink or paint.

Description

Technical field [0001] The invention relates to an anti-counterfeiting material and a preparation method thereof, in particular to a preparation method of microstructure particles with interference fringes. Background technique [0002] The application of anti-counterfeiting technology in various industries can help consumers quickly identify the authenticity of products, protect consumer rights, and help corporate users combat counterfeit products, prevent batch manufacturing, protect corporate brands, maintain corporate images, and avoid economic losses. The anti-counterfeiting technologies usually used in the packaging field are mainly used as follows: precision printing, laser holographic printing, metal wire, fluorescent dyes, magnetic dyes, thermal dyes, microprinting, steel molding, etc. These technologies have 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 structur...
