    摘要： 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 hydrocarbon reaction solvent, wherein the hydrocarbon 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 hydrocarbon reaction solvent and dried. The dried toner particles are then redispersed in a carrier liquid that is different from the reaction solvent, wherein the carrier liquid comprises less than about 10% aromatic components by weight and has a Kauri-Butanol number less than about 30 mL, to form a redispersed liquid electrographic toner composition. Preferred carrier liquids are silicone oils. Products and kits are also provided.

    摘要： A method of producing an image on a final image receptor from image data in a multiple pass electrophotographic system is provided. The method comprises the steps of applying transfer assist material to an intermediate transfer member and providing at least one development unit comprising a photoreceptive element and charged toner particles. During each complete processing cycle of an intermediate transfer member, a toned image is created and transferred to the intermediate transfer member by application of a bias. In multiple processing cycles of the intermediate transfer member, the transfer assist material and the at least one toned image thereby form a composite image layer on the intermediate transfer member. The method further comprises contacting the composite image layer with a final image receptor while applying a bias that is sufficiently strong to transfer at least a portion of the composite image layer to the final image receptor.

    摘要： The invention provides dry electrographic toner compositions comprising toner particles. The toner particles comprise polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions prepared from an organosol reaction process utilizing a liquid carrier reaction medium having a Kauri-Butanol number less than about 30 mL. The S material portion comprises at least one soluble component and at least one non-sorptive component, wherein the non-sorptive component is the reaction product of monomers having an absolute difference in Hildebrand solubility parameter from the liquid carrier of about 3.0 MPa1/2 or greater. Additionally, dry electrographic toner compositions are provided wherein the toner particles comprise polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions. The S material portion of the amphipathic copolymer has an average Hildebrand solubility parameter of from about from about 16 MPa1/2 to about 17.3 MPa1/2, and comprises at least one non-sorptive component having an average Hildebrand solubility parameter that is at least about 0.4 MPa1/2 greater than the average Hildebrand solubility parameter of the S material portion. The resulting dry toner composition can exhibit excellent final image durability characteristics, and can also provide excellent images at low fusion temperatures on a final image receptor.
