TONER COMPOSITIONS FOR RECOGNIZING SIGNS APPLIED IN MAGNETIC INKS Russian patent published in 2020 - IPC G03G9/83 

FIELD: printing equipment.

SUBSTANCE: presented versions of implementation relate to toner compositions for recognition of signs, applied with magnetic inks ("MICR"), and suitable for use in xerographic printing systems with offset printing lithography quality. Disclosed group of inventions includes versions of MICR toner compositions. At that, the MICR toner composition (for recognition of signs applied with magnetic inks) contains: a toner particle, additionally containing: cross-linked polyester resin, magnetite, present in toner in amount of 10 to 25 % and surface additive applied on surface of toner particle, wherein toner has residual magnetisation from 5 to 15 emu/g.

EFFECT: technical result consists in improvement of efficiency and expansion of applications of HSD system with fifth section by developing toner for fifth section, having capabilities of MICR, for operation in fifth xerographic section.
