Patent ID: 7432033

Claim:
A method of preparing a liquid toner composition for use within an electrophotographic printing apparatus, comprising the steps of: 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) and a visual enhancement additive in the reaction solvent; 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 a Kauri-Butanol number less than about 30 mL to form a liquid electrographic toner composition; wherein the step of redispersing the dry toner particle composition of step d) is performed within the electrophotographic printing apparatus.
