A pigment composition in which a pigment is finely dispersed and has excellent temporal stability. A pigment composition containing a pigment and a dispersant, wherein the dispersant includes (a) a repeating unit represented by the following general formula (1) and (b) a repeating unit having an ionic group. A pigment composition which is a coalescence. (In the formula, R 1 is H, a methyl group, L 1 is * —COO—, * —OCO—, * —CONH—, * —CONR 3 — (R 3 is H or an alkyl group having 1 to 6 carbon atoms). ), Or a phenylene group, * is a bond connected to the main chain, L 2 is a single bond, a divalent linking group formed by combining one or more selected from the following linking group group, and Ar has 8 carbon atoms. A monovalent group derived from the above condensed aromatic ring, a hetero ring condensed with an aromatic ring, or a benzene ring in which two or more are connected.) (Linked group group) An alkylene group having 1 to 12 carbon atoms, an alkenylene group having 2 to 12 carbon atoms, —CO—, —NR 7 — (R 7 is H or an alkyl group having 1 to 6 carbon atoms), —O—, —S—. , -SO -, - SO 2 - [Selection figure] None |
