Problems solved by technology

[0003] At present, the main components of blue toner used in laser printers are organic pigments, and their color durability is poor. The blue imprints and color graphics printed with these toners are not stored for a long time, and it is difficult to adapt to archival documents and imprints. long-term storage requirements
In addition, the above-mentioned toners have no anti-counterfeiting performance, and the color graphic materials printed with these toners also have no anti-counterfeiting performance, especially the printed signatures, stamps and other imprints are difficult to distinguish the authenticity from the fake, which is easy to give counterfeiters a sense of security. take the opportunity

Abstract

This invention discloses a kind of durability guard against false blue carbon dust used for laser printer and its preparation method. It is produced by mixing, 80-90 portion polyester resin, 5-10 portion polypropylene wax, 3-9 portion electric charge conditioning agent , 7-10 portion iron blue , 10-20 portion ultraviolet fluorescent powder, 2-4 dimethyl two chlorine silane and 7-10 portion six methyl two silicons nitrogen alkane, and doing the following steps such as molding, smashing and sifting. Use this laser printer durability guard against false blue carbon dust print color picture culture and blue print, not only the color's durability is good, be able to satisfy the request that the file reporters, need to save for a long time, it can also differentiate out true-false, has the function of guards against the false, makes the false maker has no loophole to exploit. Especially be applied to print reporters such as signature, and file.

Description

technical field [0001] The invention relates to a carbon powder and a preparation method thereof. Specifically, it is durable anti-counterfeiting blue toner for laser printers used to print archival graphic materials or anti-counterfeiting marks. Suitable for ordinary laser printers or color laser printers. Background technique [0002] With the advancement of science and technology, the level of office automation is getting higher and higher, and archives documents including signatures and seals are gradually replaced by traditional manual operations with automatic printing by laser printers. The use of laser printers to automatically print archival documents requires that the toner must have color durability. Only in this way can the long-term preservation requirements of archival documents be met. [0003] At present, the main components of blue toner used in laser printers are organic pigments, and their color durability is poor. The blue imprints and color graphics pr...
