Study of Reversible Thermo-chromic Coated Anticounterfeit Package Paper and Its Anti-counterfeit Properties

摘要

In this paper,the reversible thermo-chromic coating formulation were studied by changing the ingredient and the amount of pigment of coating formulation,and the anti-counterfeit properties of coated anti-counterfeit package paper were also discussed.It showed that the viscosity of the coating color system decreased with the addition of the dispersant agent.The formulation can increase the anti-counterfeit properties of the reversible thermo-chromic coated package paper.The color difference of the reversible thermo-chromic increased with the increasing of the reversible thermo-chromic materials.The optimum dosage of the reversible thermo-chromic in the coating color system was 2-4%.
