The present invention provides an organosol and a liquid ink containing the same. The liquid ink is a carrier liquid; Graft copolymers comprising a (co) polymer steric stabilizer covalently bonded to a thermoplastic (co) polymer core that is insoluble in the carrier liquid; And a colorant, wherein the steric stabilizer comprises a unit derived from 3,3,5-trimethylcyclohexyl methacrylate, and wherein the thermoplastic (co) polymer core has a (meth) acrylate type having an aliphatic amino radical. Derived from at least one polymerizable monomer selected from the group consisting of monomers, nitrogen-containing heterocyclic vinyl monomers, N-vinyl substituted ring-like amide monomers, aromatic substituted ethylene monomers containing amino radicals and nitrogen-containing vinylether monomers It characterized in that it comprises a unit. Using the organosol of the present invention, it is possible to prepare liquid electrophotographic and electrograph ink compositions with improved dispersion stability, blocking resistance and charge forming ability, which can improve print quality and ink transfer performance. |
