Abstract

The invention provides a zinc-sulfide-containing dual-wavelength light-absorption aquosity anti-forgery ink easer preparation technology. Nanometer zinc sulfide, deionized water and surfactants are dispersed to be even in an ultrasonic mode, and nanometer zinc sulfide solution is obtained. PEDOT solution with solid content of 1.3-1.7% and mixed with polystyrolsulfon acid is mixed with the deionized water, then anion surfactants are added, evenness is achieved through ultrasonic dispersion, and solution A is obtained. The nanometer zinc sulfide solution is mixed with the solution A to obtain mixed solution B. The mixed solution B is heated to 40-70 DEG C, alcohol solvents and powder with the diameter of 200-1000 nm are added in the mixed solution B after stirring, reaction is carried out for 40-60 minutes, and finally zinc-sulfide-containing dual-wavelength light-absorption aquosity anti-forgery ink easer is obtained. The anti-forgery ink easer has an absorption function in an infrared band of 1000-1200 nm and an ultraviolet band of 300-330 nm, and can be used as aquosity anti-forgery ink easer.

Description

technical field [0001] The invention relates to a preparation process of an anti-counterfeiting ink additive, in particular to a preparation process of a dual-wavelength light-absorbing water-based anti-counterfeiting ink additive containing zinc sulfide. Background technique [0002] Anti-counterfeiting inks are widely used in the printing industry, and optical anti-counterfeiting inks are an important part of anti-counterfeiting inks. At present, optical anti-counterfeiting inks in securities printing are mainly ultraviolet anti-counterfeiting inks, which are widely used in the market, but the problem is that their anti-counterfeiting capabilities are low and easy to be imitated; in order to meet the anti-counterfeiting needs of the market, it is urgent to develop new anti-counterfeiting technology. Contents of the invention [0003] Aiming at the above deficiencies, the present invention provides a process for preparing a dual-wavelength light-absorbing water-based ant...
