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 present invention relates to methods of drying and recovering toner particles from a liquid carrier. The methods are very effective to generate discrete, substantially non-agglomerated dry toner particles in a manner that preserves the particle size and particle distribution of the wet particles. The resultant dried toner particles free-flowing with a relatively narrow particle size distribution. The present invention uses electrical phenomena to help transfer charged toner particles from a liquid carrier onto a substrate surface. In practical effect, the particles are electrically plated onto the surface. Because the resultant coating has a relatively large drying surface area per gram of particle incorporated into the coating, drying may occur relatively quickly under moderate temperature and pressure conditions. After drying, the dried toner particles are readily recovered and may then be used in dry or even wet toners for electrophotographic applications.
