    • 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.
    • 液体油墨包括(a)贝壳杉脂丁醇值小于30的载液; (b)包含共价键合到不溶于载体液体的热塑性(共)聚合物核心的(共)聚合物空间稳定剂的接枝共聚物; 和(c)着色剂,其中所述空间稳定剂包含衍生自3,3,5-三甲基环己基甲基丙烯酸酯的单元,所述热塑性(共)聚合物芯包含衍生自至少可聚合单体的单元,所述可聚合单体选自(甲基) 具有脂族氨基的丙烯酸酯,含氮杂环乙烯基单体,N-乙烯基取代的环状酰胺单体,含有氨基的芳香族取代的乙烯单体和含氮乙烯基醚单体。 有机溶胶提供改进的液体电子摄影和电印油墨组合物,其具有改进的分散稳定性,带电性和抗粘连性,从而获得改进的印刷质量或油墨转印性能。
