PROBLEM TO BE SOLVED: To provide an ink composition that has excellent curability to irradiation with an active radiation while an image obtained by curing the ink composition has excellent flexibility, and to provide an inkjet recording method, a printed material, and a method for producing a planographic printing plate that employ the ink composition.SOLUTION: There are provided: an ink composition that includes (A) N-vinyl lactams, (B) a monomer represented by formula (I) or formula (II), and (C) a radical polymerization initiator; and an inkjet recording method, a printed material, and a method for producing a planographic printing plate that employ the ink composition. In formula (I) and formula (II), Rdenotes a hydrogen atom, a halogen atom, or a 1-4C alkyl group, Xdenotes a divalent linking group, Rand Reach independently denotes a substituent, k denotes an integer of 1-6, q and r each independently denotes an integer of 0-5, and n denotes a cyclic hydrocarbon structure. |
