1. A pigment-dispersed composition comprising at least a polymer compound (A-1) having at least one selected from the structural units represented by the following formulae (1) to (3), a pigment (B), and a solvent (C): wherein R1, R2, R5, R6, R7, R8, R11, R12, R13, R14, R19 and R20 each independently represents a hydrogen atom; R3, R4, R9, R10, R15 and R18 each independently represents a hydrogen atom or a methyl group; R16 and R17 each independently represents a hydrogen atom or a monvalent organic group; A1, A2 and A3 each independently represents an oxygen atom, a sulfur atom or —N(R21)—, wherein R21 represents an alkyl group which may be substituted; G1, G2 and G3 each independently represents an unsubstituted alkylene group having 1 to 20 carbon atoms; X and Z each independently represents an oxygen atom, a sulfur atom or —N(R22)—, wherein R22 represents an alkyl group which may be substituted; and Y represents an oxygen atom, a sulfur atom, a phenylene group which may be substituted, or —N(R23)—, wherein R23 represents an alkyl group which may be substituted, wherein the amount of the structural units represented by formula (1) to (3) in the polymer compound (A-1) is from 20% by mole or more to less than 95% by mole. |
