Dry toner blended with wax
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 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.
