Anti-counterfeiting metamerism ink as well as preparation method and printing method of anti-counterfeiting metamerism ink

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.
