Problems solved by technology

This kind of latent image cannot be recognized as a complete pattern when viewed under normal light on one side, and the pattern needs to be separated during design. A special gravure printing machine is required for printing, and the printing overprinting accuracy is high to achieve perspective Hiding is more difficult

Abstract

The invention discloses a metallic printing ink, relating to an anti-counterfeiting printing ink which can form an anti-counterfeiting latent image by single-face printing has better anti-counterfeiting performance, wherein, the latent image can be identified by people without using special apparatus. The percentage of weight of each component is as following: 15 to 25% metallic paint, 10 to 15% high acid valence phenolic resin oil, 8 to 10% pure phenolic resin oil, 3 to 5% vapor phase silica, 15 to 20% transparent calcium carbonate, 5 to 7% surfactant, 6 to 8% polyethylene wax, 2 to 4% mineral oil, 0.3 to 0.5% drier, wherein the metallic paint is any one of the flake silver powder, aluminium powder, copper powder, or the mixture of the two or three components. The invention is applicable for single-face printing anti-counterfeiting perspective latent image on various carriers, such as different securities or the carriers of plastic, rubber and glass with certain transparence.

Description

technical field [0001] The invention relates to an ink for anti-counterfeiting printing, in particular to a metal ink containing metal pigments for printing anti-counterfeiting latent images. Background technique [0002] Latent image is an anti-counterfeiting technology that hides specific patterns at normal viewing angles and observes and recognizes them under specific observation conditions. It is a technology widely used in the field of anti-counterfeiting printing. It has concealed anti-counterfeiting and easy identification. features. [0003] At present, the most widely used latent image technology is to use colorless fluorescent ink printing, and the printed pattern is hidden under visible light and clearly visible under ultraviolet light. But this kind of latent image requires the help of a specific instrument (ultraviolet light source), and the technical threshold for counterfeiting is relatively low, which has been broken by counterfeiters, and the effectiveness ...
