Patent ID: 8728687

Claim:
A colored curable composition comprising: (A) a resin comprising (i) a main chain portion containing a nitrogen atom, (ii) a group X that has a functional group having a pKa of 14 or less and is bonded to a nitrogen atom present in the main chain portion, and (iii) an oligomer chain or polymer chain Y having a number average molecular weight of from 500 to 1,000,000 in a side chain; (B) a pigment; (C) a solvent; (D) a photopolymerization initiator; and (E) a compound containing an ethylenically unsaturated double bond, wherein: the functional group having a pKa of 14 or less of the resin (A) is a functional group selected from a carboxylic acid, a sulfonic acid, or —COCH 2 CO—, the photopolymerization initiator (D) comprises at least one oxime-based compound, the resin (A) includes a repeating unit represented by general formula (I-1), a repeating unit represented by general formula (I-2), and a repeating unit represented by general formula (I-3): wherein in the general formulae (I-1) and (I-2), R 1 s and R 2 s each independently represent a hydrogen atom, a halogen atom, or an alkyl group; a's each independently represent an integer of 1 to 5; * represents a linking portion between the repeating units; X represents the group containing a functional group having a pKa of 14 or less selected from a carboxylic acid, a sulfonic acid, or —COCH 2 CO—; and Y represents the oligomer chain or polymer chain having a number average molecular weight of from 500 to 1,000,000; wherein in general formula (I-3), R 1 s and R 2 s each independently represent a hydrogen atom, a halogen atom, or an alkyl group, a's each independently represent an integer of 1 to 5; * represents a linking portion between the repeating units; and (Y′) − represents an oligomer chain or polymer chain having an anion group, which has a number average molecular weight of 500 to 1,000,000, and the content of the repeating unit represented by general formula (I-1) is from 3 to 50% by mole, the content of the repeating unit represented by general formula (I-2) is from 30 to 70% by mole, and the content of the repeating unit represented by general formula (I-3) is from 1 to 10% by mole, with respect to the total amount of repeating units contained in the resin (A).
