Abstract
The invention relates to an anti-counterfeiting fluorescent pigment, belonging to the field of pigments. The invention provides the anti-counterfeiting fluorescent pigment, and the pigment of the anti-counterfeiting fluorescent pigment is of a fluorescent compound, namely Y2O3: Eu, Er. The anti-counterfeiting fluorescent pigment is of an oxide of an inorganic matter, so that the oxide can emit fluorescence under ultraviolet light, has stable natures and can still stably function during long-term storage.
Description
Technical field
The present invention relates to a kind of anti-fake fluorescent pigment, belong to the pigment field.
Background technology
Printer with security pigment comprise Ultraluminescence variable color, day optical excitation variable color, infrared anti-false, photochromic, temperature-sensitive is false proof, pressure-sensitive false proof carbon dust etc., wherein, the word that utilizes ultraviolet ray excited false proof carbon dust to print, show under uviolizing bright-coloured fluorescence is arranged, be for the needs such as product false proof, vital document be false proof, the contents such as concealed anti-false mark, word, image are carried out the pigment that spray ink Printing is used.Antiforge content with the concealed anti-false print cartridge is printed is shown as invisible under ordinary ray; Only under specific UV-light environment, the false proof content of printing is just high-visible.
Printer is divided into two kinds, coloured fluorescent ink and colorless fluorescent printing ink with false proof carbon dust Ultraluminescence carbon dust, the picture and text naked eyes of coloured fluorescent ink printing as seen, colorless fluorescent printing ink is invisible, but both all needs can show fluorescence under uviolizing.General fluoresent printing ink fluorescent material, usually by solvent, tinting material, tensio-active agent, the one-tenth such as pH adjusting agent, siccative and other necessary additive are grouped into.Yet the pigment in the present fluorescence falsification preventing carbon dust that uses mostly is pigment dyestuff, and its fixation time is shorter, is unfavorable for the use of the encrypt file of need long-term storage.
Summary of the invention
The invention provides a kind of anti-fake fluorescent pigment, this anti-fake fluorescent pigment is the inorganics oxide compound, and this oxide compound sends fluorescence under ultraviolet light, and stable in properties, and long-term storage still can be stablized the performance effect.
