Abstract

The invention discloses anti-counterfeiting metamerism ink. The anti-counterfeiting metamerism ink is prepared from 50 to 60 mass percent of metamerism pigments, 14 to 20 mass percent of silicon modified acrylate resin, 6 to 9 mass percent of butyl acrylate, 4 to 8 mass percent of epoxy resin, 2 to 3 mass percent of near-infrared absorbing agents, 3 to 5 mass percent of isopropanol, 3 to 5 mass percent of absolute ethyl alcohol, 4 to 8 mass percent of deionized water, 0.5 to 1.5 mass percent of secondary butyl amine,0.5 to 1 mass percent of terpilenol, 0.2 to 0.5 mass percent of antifoaming agents and 0.1 to 0.3 mass percent of flatting agents. The invention also discloses a preparation method of the anti-counterfeiting metamerism ink and a printing method adopting the anti-counterfeiting metamerism ink. The fusion of various anti-counterfeiting technologies in the same anti-counterfeiting region is realized; the anti-counterfeiting region shows different colors under the illumination of different light sources; the recognition is easy; the accepting degree of people on products can be improved, so that the product has multiple anti-counterfeiting performance; the anti-counterfeiting intensity is high.

Description

Technical field: [0001] The invention relates to the technical field of packaging printing, in particular to an anti-counterfeiting metamerism ink, a preparation method of the metamerism ink, and a printing method using the metamerism ink. Background technique: [0002] Anti-counterfeiting ink plays a pivotal role in today's social security field and has been widely used in many fields. Anti-counterfeiting ink refers to a type of ink with anti-counterfeiting function, that is, a special type of ink that is made by adding anti-counterfeiting materials to the ink binder and undergoing a certain processing technology. Metameric inks are basically the same color as ordinary inks under natural light, but when observed with special instruments (such as infrared scanners or filters, etc.), it will be found that the hue and contrast of the two inks have changed greatly. Chromatic aberrations stand out. Metameric inks show basically the same spectral curves in the high-sensitivity ...
