Abstract

The invention relates to anti-fake carbon powder for a printer, belonging to the field of paints. The anti-fake carbon powder for the printer contains a fluorescent compound Y2O3:Eu,Er. The anti-fake carbon powder adopts an inorganic substance as a fluorescent substance and can emit fluorescence under ultraviolet light rays; the property is stable; and the anti-fake carbon powder can still stably develop the effect after being stored for a long time.

Description

technical field [0001] The invention relates to an anti-counterfeit carbon powder for printers, which belongs to the field of pigments. Background technique [0002] Anti-counterfeiting pigments for printers include ultraviolet fluorescent discoloration, sunlight-induced discoloration, infrared anti-counterfeiting, photochromism, heat-sensitive anti-counterfeiting, pressure-sensitive anti-counterfeiting toner, etc. Among them, the text printed by ultraviolet-ray excited anti-counterfeiting toner appears bright and vivid under ultraviolet light. Fluorescence is a pigment used for inkjet printing of invisible anti-counterfeiting marks, text, images and other content for product anti-counterfeiting, important document anti-counterfeiting and other needs. The anti-counterfeiting graphic content printed by the invisible anti-counterfeiting ink cartridge is invisible under ordinary light; only under a specific ultraviolet light environment, the printed anti-counterfeiting content ...
