Abstract

The present invention proposes a method for making red toner for color laser printing with a multi-component mixed resin. By adding polyester resin and epoxy resin to the copolymerized polystyrene-acrylic resin, the frictional electrification performance of the powder can be improved; the powder has Lower melting temperature and relatively high glass transition temperature improve thermal performance and improve melting characteristics at relatively low temperatures; by adding the above three resins, the powder fixing performance and developing performance can be improved, and the fixing temperature range is wider. The fixing effect is better, the color mixing is more uniform, and the fixation firmness is improved, which meets the needs of various printers and expands the applicable surface of powder.

Description

technical field [0001] The invention relates to the preparation technology of red toner for color laser printing, in particular to a method for making red toner for color laser printing with multi-component mixed resin. Background technique [0002] At present, with the increasing use of color printing, customers have higher and higher requirements for printing or copying quality, and the fixing and developing toner originally used in black printers are less and less able to meet the demand. The specific performance is: (1) The fixing temperature must meet the requirements of the fixing range of the color copier; (2) The fixing stability is not good enough: (3) The color reproduction degree is not enough; (4) The fixing degree is low and ghosting is easy to occur; ( 5) In addition, due to the development of more and more printers of various types, it is difficult to have a kind of toner that can meet the needs of multiple printers. Contents of the invention [0003] In vi...
