The present invention provides an aqueous ink composition including at least a sensitizing dye represented by the following Formula (i), an ethylenically unsaturated bond-containing water-soluble polymerizable compound, a polymerization initiator and water:
wherein, in Formula (i), X represents O, S or NR; n represents an integer of 0 or 1; R represents a hydrogen atom, an alkyl group or an acyl group; each of R1, R2, R3, R4, R5, R6, R7 and R8 independently represents a hydrogen atom or a monovalent substituent, provided that any neighboring two of R1, R2, R3 and R4 may be bonded to each other to form a ring, and R5 and R7 or R8, or R6 and R7 or R8, may be bonded to each other to form an aliphatic ring but do not form an aromatic ring.
本发明提供了一种水性油墨组合物,其中至少包括一种由下式(i)表示的敏化染料、一种含乙烯不饱和键的水溶性可聚合化合物、一种聚合引发剂和水:
其中,在式 (i) 中,X 代表 O、S 或 NR;n 代表 0 或 1 的整数;R 代表氢原子、烷基或酰基;R1、R2、R3、R4、R5、R6、R7 和 R8 中的每一个独立地代表一个氢原子或一个单价取代基,但 R1、R2、R3 和 R4 中的任意相邻两个可相互键合形成一个环,R5 和 R7 或 R8 或 R6 和 R7 或 R8 可相互键合形成一个脂肪族环,但不形成一个芳香族环。
