An ink composition is provided that includes (A) a radically polymerizable compound, (B) a radical polymerization initiator; and (C) a colorant, and the radically polymerizable compound (A) includes at least one type of compound represented by Formula (Ia) and/or compound represented by Formula (Ib) and at least one type of compound represented by Formula (II)
(in Formula (Ia), Formula (Ib), and Formula (II), R 1 , R 3 , and R 5 independently denote a hydrogen atom or a methyl group, A 1 to A 3 independently denote a single bond or a divalent linking group, R 2 and R 4 independently denote a monovalent substituent, m denotes an integer of 0 to 13, n denotes an integer of 0 to 19, when m is an integer of 2 to 13 the R 2 s may be identical to or different from each other, and when n is an integer of 2 to 19 the R 4 s may be identical to or different from each other). There is also provided an inkjet recording method that includes (a 1 ) a step of discharging the ink composition onto a recording medium, and (b 1 ) a step of curing the ink composition by irradiating the discharged ink composition with actinic radiation. |
