Organosol liquid toner including amphipathic copolymeric binder having crosslinkable functionality

本发明涉及电记录应用中的液体调色剂组合物。有机溶胶液体调色剂组合物包含分散于非水性液体载体中的粘合剂颗粒，其中颗粒衍生自含有一种或多种可交联两亲共聚物的成分。该有机溶胶易于与另外的成分组合，如一种或多种视觉增强添加剂和其它所需的成分，并进行混合处理以形成液体调色剂组合物。本发明也描述了制备和用电记录术印刷由这些有机溶胶衍生的液体调色剂的方法。 A liquid electrographic toner composition comprises liquid carrier with Kauri-Butanol number less than 30, and toner particles. The toner particles are dispersed in liquid carrier. The toner particles comprise complementary cross-linkable functionalities and amphiphatic copolymer(s). The amphiphatic copolymer(s) comprises S and D material portions. The portion(s) of cross-linkable functionalities are added into amphiphatic copolymer(s).
