    摘要： A liquid ink comprises (a) a carrier liquid having a Kauri-Butanol number less than 30; (b) a graft copolymer comprising a (co)polymeric steric stabilizer covalently bonded to a thermoplastic (co)polymeric core that is insoluble in the carrier liquid; and (c) a colorant, wherein the steric stabilizer comprises units derived from 3,3,5-trimethylcyclohexyl methacrylate, and the thermoplastic (co)polymeric core comprising units derived from at least a polymerizable monomer selected from the group consisting of (meth)acrylates having aliphatic amino radicals, nitrogen-containing heterocyclic vinyl monomers, N-vinyl substituted ring-like amide monomers, aromatic substituted ethylene monomers containing amino radicals, and nitrogen-containing vinylether monomers. The organosol provides improved liquid electrophotographic and electrographic ink compositions with improved dispersion stability, chargeability, and blocking resistance so that improved print quality or ink transfer performance are obtained.

    摘要： The invention provides liquid toner compositions in which the polymeric binder is chemically grown in the form of copolymeric binder particles dispersed in a liquid carrier. The polymeric binder includes one amphipathic copolymer comprising one or more S material portions and one or more D material portions, wherein the components of the composition comprise sufficient proton donor and proton acceptor functionality to provide a three dimensional gel of controlled rigidity which can be reversibly reduced to a fluid state by application of energy. The toners as described herein surprisingly provide compositions that are particularly suitable for electrophotographic processes wherein the transfer of the image from the surface of a photoconductor to an intermediate transfer material or directly to a print medium is carried out without film formation on the photoconductor.

    摘要： A system for printing a liquid toner is provided comprising a liquid electrographic toner composition comprising a liquid carrier having a Kauri-Butanol number less than about 30 mL and a plurality of charged toner particles dispersed in the liquid carrier, wherein the toner particles comprise a polymeric binder. The system also comprises a charge control adjuvant having limited solubility in the liquid carrier. The charge control adjuvant preferably is present in the liquid carrier in an amount in excess of the solubility of the adjuvant in the liquid carrier. Alternatively, the charge control adjuvant may be dispersed in a matrix having limited solubility in the liquid carrier or encapsulated within a matrix to form microcapsules having limited solubility in the liquid carrier. The charge control adjuvant in any of the above forms may be provided in a number of formats for release into the toner composition as needed. The charge control adjuvant is released into the toner composition as needed to provide charge control relative to the bulk conductivity of the toner composition and/or the charge per unit mass of the toner particles.

    摘要： Negative liquid electrographic toner compositions are provided comprising a liquid carrier having a Kauri-Butanol number less than about 30 mL and a plurality of negatively charged toner particles dispersed in the liquid carrier. The toner particles comprise a polymeric binder comprising at least one amphipathic graft copolymer comprising one or more S material portions and one or more D material portions. The toner composition additionally comprises a charge control adjuvant that is an acid or a base. These compositions have surprising bulk conductivity and charge per mass properties, particularly as the toner particles are depleted from the toner composition during printing operations.
