ABSTRACT:
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.
