Patent ID: 7320853

Claim:
A method of preparing a liquid electrographic toner composition comprising a) preparing a polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions in a reaction solvent, wherein the reaction solvent comprises less than about 10% aromatic components by weight and has a Kauri-Butanol number less than about 30 mL; b) formulating toner particles comprising the polymeric binder of step a) in the reaction solvent and a visual enhancement additive; c) drying a plurality of toner particles as formulated in step b) to provide a dry toner particle composition; and d) redispersing the dry toner particle composition of step c) in a carrier liquid having substantially the same chemical constitution as the reaction solvent to form a redispersed liquid electrographic toner composition.
