    摘要: The invention provides liquid electrographic toner compositions comprising a liquid carrier having toner particles and at least one soluble polymer 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 soluble polymer is present in an amount of from about 1% to about 10% by weight based on toner particle weight. The absolute difference in Hildebrand solubility parameters between the soluble polymer and the liquid carrier is less than about 3.0 MPa1/2. In one aspect of the invention, the soluble polymer that is incorporated in the toner composition has no more than about 30% weight ratio chemical constitution variance from the chemical constitution of the S material portion of the amphipathic copolymer. In another aspect of the invention, the soluble polymer that is incorporated in the toner composition has no acidic functionality having a pKa greater than 8, and has no basic functionality having a pKa of its conjugate acid that is greater than 8. Methods of making these compositions are also provided.

    摘要: 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.
