An ink composition is provided that includes (A) at least one polymerizable compound selected from the group consisting of a monofunctional radically polymerizable monomer having an aliphatic cyclic structure, an N-vinyllactam, and an aromatic monofunctional radically polymerizable monomer, (B) a radical polymerization initiator, (C) a pigment, and (D) a graft copolymer having a repeating unit represented by the Formula below in a graft chain.
(In the Formula, R denotes a hydrogen atom or a methyl group, X denotes a single bond, - O-, -CO-, -COO-, -CONR1-, -OCO-, or a phenylene group, R1 denotes a hydrogen atom, an alkyl group, an aryl group, or an aralkyl group, L denotes a single bond or a divalent linking group, Z denotes -NR2R3, R2 and R3 independently denote a hydrogen atom, an alkyl group, an aryl group, or an aralkyl group, and R2 and R3 may be bonded to each other to form a ring.) There are also provided an inkjet recording method that includes a step of discharging the ink composition above onto a recording medium and a step of curing the ink composition by irradiating the discharged ink composition with actinic radiation, and a printed material recorded by the inkjet recording method.
本发明提供了一种油墨组合物,其中包括:(A) 至少一种可聚合化合物,该化合物选自由脂肪族环状结构的单官能团可辐射聚合单体、N-乙烯内酰胺和芳香族单官能团可辐射聚合单体组成的组;(B) 自由基聚合引发剂;(C) 颜料;(D) 接枝共聚物,该接枝共聚物的接枝链中具有下式所代表的重复单元。
(式中,R 表示氢原子或甲基,X 表示单键、-O-、-CO-、-COO-、-CONR1-、-OCO-或亚苯基,R1 表示氢原子、烷基、芳基或芳烷基、L 表示单键或二价连接基团,Z 表示-NR2R3,R2 和 R3 独立地表示氢原子、烷基、芳基或芳烷基,R2 和 R3 可相互键合形成环。)还提供了一种喷墨记录方法,该方法包括将上述墨水组合物排放到记录介质上的步骤和通过用阳极辐射照射排放的墨水组合物来固化墨水组合物的步骤,以及用该喷墨记录方法记录的印刷材料。
