Pigment-dispersed composition, curable composition, color filter and production method thereof

A curable composition comprising 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), a solvent (C), and a photopolymerization initiator (E):

• 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 represent 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 represent 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.
