Embodiment 1

[0080] Photocurable screen printing metal microstructure material anti-counterfeiting ink composition:

[0081] Weight percent:

[0082]

[0083]The metal microstructure material used: the shape is an equilateral triangle, the side length is about 40 microns, three-layer structure, the middle is a metal layer, the metal layer is made of aluminum with a low boiling point, and the three-dimensional microstructure material is a fluorescent material layer on both sides.

[0084] The preparation method is to put all the raw materials required for the metal microstructure material anti-counterfeiting ink composition at a temperature of 45-50°C into a stirring device, start stirring, and first stir at 200 rpm for 40 minutes to make the solid The material is fully wetted by the liquid material, and then stirred at a speed of 1000 rpm for 45 minutes to disperse, so that the flake pigment and the three-dimensional microstructure metal pigment are wrapped by the ink binder, and the pr...

Abstract

The present invention discloses an anti-counterfeiting ink composition containing a micro-structure material, and a preparation method thereof. The anti-counterfeiting ink composition contains, by weight, 0.01-60% of a three-dimensional micro-structure material, 1-95% of a connection material, 0-30% of a pigment, and 0-70% of an ink auxiliary agent, wherein the three-dimensional micro-structure material is a single layer metal micro-structure or a function layer-containing multi-layer material adopting a metal as a substrate, and a particle size is 2-100 mum. According to the present invention, the specific shape pattern of a micro-structure metal pigment can form an anti-counterfeiting feature, and qualitatively read other anti-counterfeiting features are integrated on the micro-structure metal pigments based on provision of the characteristic of the micro-structure metal pigment, such that the composite anti-counterfeiting level of the pigment composition is enhanced; and the read information of the integrated anti-counterfeiting material is adopted as a cipher key to read extension information stored in a client terminal or a central database.

Description

technical field [0001] The present invention relates to a kind of anti-counterfeiting ink composition containing microstructure material and its preparation method, more specifically, the present invention relates to a kind of anti-counterfeiting ink composition containing three-dimensional microstructure material with metal as the base material and having anti-counterfeiting features. Its preparation method. Background technique [0002] Special pigments have been widely used in the field of anti-counterfeiting, such as printing banknotes, identity documents, securities, and even directly applied to commercial items for brand anti-counterfeiting. For example, the optical color-changing ink currently used in RMB 100, the number "100" printed on the lower left corner of the banknote changes color with the change of viewing angle, which has obvious anti-counterfeiting effect. The color-changing effect cannot be reproduced by ordinary color copiers, and users can judge the aut...
