WET ELECTRO-PHOTOGRAPHIC TONER COMPOSITION COMPRISING AMPHIPATHIC COPOLYMER BINDER HAVING CRYSTALLINE COMPONENT, PREPARATION METHOD THEREOF AND ELECTRO-PHOTOGRAPHIC IMAGING METHOD USING THE SAME

摘要

PURPOSE: Provided is a wet electro-photographic toner composition comprising organosol containing an amphipathic copolymer, which has excellent imaging property such as fixing property. CONSTITUTION: The wet electro-photographic toner composition comprises: (a) a liquid carrier having a kauri butanol number less than 30 ml; and (b) multiple toner particles dispersed in the liquid carrier. In the toner composition, the toner particles comprise a polymeric binder containing at least one amphipathic copolymer having at least one S(solvation) material part and at least one D(dispersion) material part. Further, at least one D material part has one or more polymerizable and crystallizable compound.
