    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： A photoreceptor with good mechanical and physical properties is provided with an overcoat layer comprising a copolymer of an α,β-ethylenically unsaturated carboxylic acid and an α,β-ethylenically unsaturated monomer wherein the weight percent of the α,β-ethylenically unsaturated carboxylic acid is at least 10% by weight of the copolymer. The copolymer may comprise an α,β-ethylenically unsaturated carboxylic acid and an α,β-ethylenically unsaturated monomer wherein the copolymer has an acid value of at least 60 mg KOH/g the copolymer. The copolymer may be present in a blend with a second polymer or copolymer comprised of units derived from a second α,β-ethylenically unsaturated monomer that is different from the an α,β-ethylenically unsaturated carboxylic acid and/or the α,β-ethylenically unsaturated monomer. The copolymer or the copolymer blend may be present in a layer that is crosslinked or crosslinkable, the crosslinking being effected through a distinct crosslinking agent that reacts with groups) on the an α,β-ethylenically unsaturated carboxylic acid or the α,β-ethylenically unsaturated monomer.
