Abstract:
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 a substantial portion of the wax is entrained in the toner particle and a substantial portion 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, and milling the particles before or after formulation as toner particles with wax in the liquid carrier prior to drying to form the dry toner composition. These toner compositions provide images having excellent durability and erasure resistance properties at low fusion temperatures and with little undesired offset.
