    摘要： The invention provides liquid electrographic toner compositions comprising a liquid carrier having toner particles dispersed in the liquid carrier. The liquid carrier has a Kauri-Butanol number less than about 30 mL. 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 toner composition additionally comprises a dispersed wax component associated with the toner particle. These toner particles can exhibit excellent final image durability characteristics, and can also provide toner compositions that provide excellent images at low fusion temperatures on a final image receptor.

    摘要： Dry electrographic toner compositions are provided comprising a plurality of dry toner particles, 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 dry electrographic toner composition comprises a wax associated with the dry toner particles, wherein substantially all of the wax is associated with the toner particle at the surface thereof. Methods of making electrographic toner compositions are also provided comprising preparing polymeric binder particles comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions, preparing toner particles, drying the toner particles, and milling the dry toner particles in the presence of a wax component to provide a dry toner particle composition having the wax associated with the toner particles. These toner compositions provide images having excellent durability and erasure resistance properties at low fusion temperatures and with little undesired offset.

    摘要： The invention provides liquid electrographic toner compositions comprising a liquid carrier having toner particles dispersed in the liquid carrier. The liquid carrier has a Kauri-Butanol number less than about 30 mL. 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 toner composition additionally comprises a wax component associated with the toner particle, wherein the wax component and the amphipathic copolymer each comprise at least one of a Lewis acid and a Lewis base pair in an amount sufficient to form weak, reversible intermolecular non-covalent bonds resulting from acid/base interactions between the wax component and the amphipathic copolymer. These toner particles can exhibit excellent final image durability characteristics, and can also provide toner compositions that provide excellent images at low fusion temperatures on a final image receptor.
