Abstract:
1. An ink composition comprising: (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 Formula (D1) in a graft chain (in Formula (D1), R denotes a hydrogen atom or a methyl group, X denotes —(CO)O—, —CONR 1 —, or a phenylene group, R 1 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 —NR 2 R 3 , R 2 and R 3 independently denote a hydrogen atom, an alkyl group, an aryl group, or an aralkyl group, and R 2 and R 3 may be bonded to each other to form a ring).
