Patent ID: 7303848

Claim:
A liquid electrographic toner composition comprising: a) a liquid carrier having a Kauri-Butanol number less than about 30 mL; b) a plurality of toner particles dispersed in the liquid carrier, 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; and c) a soluble polymer present in an amount of from about 1% to about 10% by weight based on toner particle weight, wherein the absolute difference in Hildebrand solubility parameters between the soluble polymer and the liquid carrier is less than about 3.0 MPa 1/2 , and wherein the soluble polymer has no more than about 30% weight ratio chemical constitution variance from the chemical constitution of the S material portion of the amphipathic copolymer.
