Patent ID: 8163447

Claim:
A colored photocurable composition for a solid state image pick-up device, the composition comprising at least (A) a dispersion resin having an unsaturation equivalent of less than 600, (B) a pigment, (C) a photopolymerization initiator, and (D) a polyfunctional photopolymerizable compound having an acidic functional group and/or an alkyleneoxy chain, wherein the dispersion resin (A) having an unsaturation equivalent of less than 600 is a polymer compound including at least one structural unit selected from the structural units represented by the following formulae (1) to (3): wherein in formulae (1) to (3), 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 a divalent organic group; 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; 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; R 1 , R 2 , R 7 , R 8 , R 13 and R 14 are a hydrogen atom; and R 3 to R 6 , R 9 to R 12 and R 15 to R 20 each independently represents a hydrogen atom or a monovalent organic group.
