description The present invention provides a high temperature resistance anti-counterfeiting composition, which comprises, by mass, 10-70% of red phosphor and 30-90% of a glass fluxing agent, wherein a chemical formula of the red phosphor is Y2yO2S:2xZ, x is more than or equal to 0.05 and is less than or equal to 0.1, a sum of x and y is 1, Z is one or a plurality of materials selected from Eu, Sm, Ga, In, Y, Dy, Tb, Gd, Yb and Er, and the glass fluxing agent comprises, by mass, 30-50% of SiO2, 0-10% of Al2O3, 10-35% of B2O3, 0-15% of ZnO, 1-10% of an alkali metal, and 0-10% of an alkaline earth metal. The high temperature resistance anti-counterfeiting composition has characteristics of wide raw material source, no pollution, good high temperature resistance, adaptability to decorating firing requirements of ceramics and glass, good anti-counterfeiting effect, durability and wear resistance.
