A liquid ink including a colorant surface-treated with a polymer comprising units derived from at least a nitrogen-containing polymerizable monomer and a process of making the same are provided. The liquid ink includes a carrier liquid, an organosol, and a colorant surface-treated by a polymer comprising units derived from at least a nitrogen-containing polymerizable monomer. Since the liquid ink includes the colorant surface-treated by a polymer comprising units derived from at least a nitrogen-containing polymerizable monomer, it exhibits improved chargeability, reduced conductivity variability and improved dispersion stability at a lower amount of charge control additive.
本发明提供了一种液体墨
水,包括用聚合物处理过的
着色剂表面,该聚合物包含至少由含氮可聚合单体衍生的单元,还提供了制造该液体墨
水的工艺。该液体墨
水包括载液、有机溶剂和表面经过至少一种含氮可聚合单体衍生单元组成的聚合物处理的
着色剂。由于液体墨
水包括由至少一种含氮可聚合单体衍生的单元组成的聚合物所处理的
着色剂表面,因此在电荷控制添加剂用量较低的情况下,液体墨
水的电荷性得到改善,导电性变化减小,分散稳定性提高。
