Abstract
The invention relates to a special carbon powder used for credit slip and letter and the related preparation technics; the carbon powder comprises a resin connecting material, a pigment, a magnetic material, a charge control agent, a parting medium and a surface modifier. The carbon powder has great difference from the existing carbon powder; because characters or patterns printed by laser printer can not be recognized with naked eyes under common light, but only can be recognized under the light of wavelength of about 365nm or about 254nm or about 980nm, thereby realizing the effect of invisible and anti-counterfeiting. By using the carbon powder, characters or patterns printed by laser printer are colorless under common light, under the light of wavelength of about 365nm, wavelength of about 254nm and wavelength of about 980nm, characters or patterns with different hues are represented, thereby realizing a better recognition effect. The invention relates to a special carbon powder for credit slip and letter, the component comprises the resin connecting material, the pigment, the magnetic material, the charge control agent, the parting medium and the surface modifier.
