Abstract
The invention discloses a thermal-alteration anti-counterfeiting coated ivory board and its production method. The thermal-alteration anti-counterfeiting coated ivory board comprises body paper. A thermal-alteration coating is added in at least one of a front side or a back side of the body paper, and weight percentage of the coating is 1 wt%-10 wt%. With the rising of temperature, color of the ivory board will be changed. When the temperature returns to normal, the ivory board returns to the original color. In addition, thermal-alteration fiber is embedded in the pulp layer. Thus, the ivory board is not easy to simply copy, print or imitated by counterfeiters. The thermal-alteration anti-counterfeiting coated ivory board has uniqueness, is easy to identify and has a good anti-counterfeiting effect.
