Abstract: A low temperature fusing dry electrographic toner composition has 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 volatile plasticizer in an amount effective to reduce the First Heat Exposure Tg by at least about 10° C. as compared to a like electrographic toner composition that does not comprise volatile plasticizer. The plasticizer is sufficiently volatile that the Second Heat Exposure Tg will increase by at least about 5° C. above the First Heat Exposure Tg. Methods of making and of using these compositions are also provided.

Abstract: A low temperature fusing dry electrographic toner composition has 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 non-volatile plasticizer in an amount effective to reduce the First Heat Exposure Tg by at least about 10° C. as compared to a like electrographic toner composition that does not comprise non-volatile plasticizer. The plasticizer plasticizer is sufficiently non-volatile that the Second Heat Exposure Tg will not increase by an amount greater than about 5° C above the First Heat Exposure Tg. Methods of making and of using these compositions are also provided.
