Patent ID: 8785087

Claim:
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 R 1 , R 2 , R 5 , R 6 , R 7 , R 8 , R 11 , R 12 , R 13 , R 14 , R 19 and R 20 each independently represents a hydrogen atom; R 3 , R 4 , R 9 , R 10 , R 15 and R 18 each independently represents a hydrogen atom or a methyl group; R 16 and R 17 each independently represents a hydrogen atom or a monvalent organic group; A 1 , A 2 and A 3 each independently represents an oxygen atom, a sulfur atom or —N(R 21 )—, wherein R 21 represents an alkyl group which may be substituted; G 1 , G 2 and G 3 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(R 22 )—, wherein R 22 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(R 23 )—, wherein R 23 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.
