Abstract

The invention discloses organic silicon modified optical-variable anti-fake ink which is prepared from the following raw materials in percentage by weight: 20-40% of optical-variable pigment, 10-40% of organic silicone modified acrylic resin, 10-20% of polyester resin, 15-30% of a solvent and 1-2% of aids. According to the organic silicon modified optical-variable anti-fake ink, the organic silicone modified acrylic resin and the polyester resin are combined as a connecting material of the optical-variable anti-fake ink, and as the organic silicone modified acrylic resin contains three curing groups, namely, carboxyl, epoxy and unsaturated double bonds, multiple curing modes can be available, thermal curing, ultraviolet curing, humid curing and air curing can be achieved in different steps, or one or more groups can be firstly cured, and then a soft non-sticky material can be prepared; the phenomena that conventional optical-variable anti-fake ink is large in curing shrinkage rate and has oxygen inhibition as single ultraviolet curing is adopted can be effectively reduced, and furthermore the gloss, the hardness, the chemical resistance and the wearing resistance of the ink can be improved.

Description

technical field [0001] The invention relates to an optically variable anti-counterfeiting ink, in particular to an organosilicon-modified optically variable anti-counterfeiting ink. Background technique [0002] Optical color-changing ink is a complex interference type anti-counterfeiting ink. Its printed matter shows two different colors with the change of human eye angle. It can integrate first-line anti-counterfeiting and packaging decoration. Packages and anti-counterfeiting labels. The color changing effect of optically variable ink is realized by the optically variable pigment in the ink. Due to the particularity of the optically variable pigment, that is, it is a flake-shaped inorganic pigment that presents two or more colors depending on the viewing angle. In order to show a better color changing effect, the theory requires that the optically variable pigment in the printed ink film It can be arranged in parallel without overlapping, so that the optical variable pi...
