A pigment dispersion that includes C.l. Pigment Yellow 185 and a polymer having a repeating unit represented by Formula (1):
wherein:
R denotes a hydrogen atom or a methyl group, J denotes -CO-, - COO-, -CONR 1 -, -OCO-, a methylene group, or a phenylene group,
R 1 denotes a hydrogen atom, an alkyl group, or an aryl group,
n denotes 0 or 1,
W denotes a single bond or a divalent linking group, and
P denotes a heterocyclic residue or aromatic quinone structure-containing residue forming a basic skeleton of an organic pigment. There are also provided an ink composition that includes C.l. Pigment Yellow 185 and a polymer having a repeating unit represented by Formula (1), and an inkjet recording method that includes a step of discharging onto a recording medium the ink composition and a step of curing the ink composition by irradiating the discharged ink composition with actinic radiation. |
