Abstract
Methods of preparing a liquid electrographic toner composition are provided, wherein a polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions is first prepared 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. Toner particles are then formulated in the reaction solvent and dried. The dried toner particles are then redispersed in a carrier liquid that has substantially the same chemical constitution as the reaction solvent to form a redispersed liquid electrographic toner composition. Products and kits are also provided.
