Abstract:
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.
