Abstract

The invention discloses degradable gravure UV anti-counterfeiting ink. The degradable gravure UV anti-counterfeiting ink comprises, by weight percentage, 20-30% of epoxidized soybean oil acrylate, 10-20% of optical-variable pigment, 15-25% of dipropylene glycol diacrylate, 20-30% of 2-phenoxyethyl acrylate, 2-5% of BP photo-initiator, 3-6% of ITX photo-initiator, 8-10% of amine initiator and 1-3% of auxiliaries. The prepared single-component gravure UV anti-counterfeiting ink has the advantages that the ink is free of solvent during use, no toxic gas is discharged, the ink is environmentally friendly, free of pollution and good in tinting power and fluidity, the color changing performance of the ink along with angle change is high, and the requirements of the anti-counterfeiting ink can be satisfied.

Description

technical field [0001] The invention relates to the technical field of inks, in particular, the invention relates to a gravure UV anti-counterfeiting ink, and also relates to its application. Background technique [0002] The gravure printing inks on the market are mainly solvent-based, and their components contain a large amount of organic solvents. During construction, a large amount of organic solvents will be volatilized and released into the air, causing pollution to the environment and not conducive to environmental protection, especially benzene Solvents are detrimental to the health of operators. Patents have reported UV gravure inks, and patent CN101486857 discloses a UV curing gravure ink, which uses alkali-soluble acrylate resins and modified epoxy acrylate resins as the main resin, and photoinitiators, pigments, fillers, dilute The prepared UV gravure printing ink has short drying cycle, stable inking performance, good scratch resistance and acid and alkali resi...
