Disclosed is an active energy ray-curable ink composition comprising a coloring agent, a binder resin, and a radically polymerizable varnish and/or a radically polymerizable monomer as main components. The coloring agent is a modified pigment wherein the surface of a pigment (A) is provided with a polymer (P) which is obtained by polymerizing a polymer (B), which is soluble in nonaqueous solvents, with at least one polymerizable unsaturated monomer (C), which is originally soluble in nonaqueous solvents but becomes insoluble or poorly soluble after polymerization. Also disclosed is a printed matter which has a coating film obtained by curing and drying the active energy ray-curable ink composition.
本发明公开了一种活性能量射线固化油墨组合物,其主要成分包括着色剂、粘合剂树脂、可辐射聚合清漆和/或可辐射聚合单体。着色剂是一种改性颜料,其中颜料(A)的表面具有聚合物(P),聚合物(P)是通过将可溶于非水溶剂的聚合物(B)与至少一种可聚合的不饱和单体(C)聚合而得到的,不饱和单体(C)原本可溶于非水溶剂,但在聚合后变得不溶或溶解性很差。还公开了一种印刷品,其涂膜是通过固化和干燥活性能量射线固化油墨组合物获得的。
