Abstract
An object of the present invention is to provide a colored curable resin composition for forming an optical filter in which the occurrence of foreign matter is reduced. The present invention relates to a colored curable resin composition containing a colorant, a resin, a polymerizable compound, and a polymerization initiator, wherein the colorant is a colorant containing a compound represented by formula (I) or formula (II).
Claims4
A colored curable resin composition comprising a colorant, a resin, a polymerizable compound, and a polymerization initiator,
- wherein the colorant is a colorant comprising a compound represented by formula (I) or formula (II):
- wherein:

- R1 represents an aryl group having 6 to 20 carbon atoms or a heteroaryl group having 3 to 20 carbon atoms, and a hydrogen atom contained in the aryl group and the heteroaryl group is optionally replaced with a halogen atom or an alkoxy group having 1 to 20 carbon atoms;
- R2 and R3 each independently represent a hydrogen atom or an alkyl group having 1 to 10 carbon atoms;
- a methylene group contained in the alkyl group is optionally replaced with an oxygen atom;
- and R2 and R3 are optionally bonded to each other to form a nitrogen atom-containing ring;
- a plurality of X1, X2, Y1, Y2, R1, R2, or R3, when present in one molecule, are optionally the same or different from each other;
- M1 represents a hydrogen atom, a monovalent metal atom, a divalent metal atom, a trivalent substituted metal atom, a tetravalent substituted metal atom, or an oxidized metal atom;

- Ar1 represents an arylene group having 6 to 20 carbon atoms or a heteroarylene group having 3 to 20 carbon atoms, and a hydrogen atom contained in the arylene group and the heteroarylene group is optionally replaced with a halogen atom or an alkoxy group having 1 to 20 carbon atoms;
- Z3 and Z4 each independently represent a hydrogen atom, N(R6)2, OR5, or SR5;
- R5 represents an alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, or a heteroaryl group having 3 to 20 carbon atoms;
- a hydrogen atom contained in the alkyl group is optionally replaced with a halogen atom;
- a methylene group contained in the alkyl group is optionally replaced with an oxygen atom;
- and a hydrogen atom contained in the aryl group and the heteroaryl group is optionally replaced with a halogen atom or an alkoxy group having 1 to 20 carbon atoms;
- R6 represents a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, wherein a hydrogen atom contained in the alkyl group is optionally replaced with an aryl group having 6 to 10 carbon atoms, and wherein a methylene group contained in the alkyl group is optionally replaced with an oxygen atom;
- a plurality of Z1, Z2, Z3, Z4, Ar1, R4, R5, or R6, when present in one molecule, are optionally the same or different from each other;
- M2 represents a hydrogen atom, a monovalent metal atom, a divalent metal atom, a trivalent substituted metal atom, a tetravalent substituted metal atom, or an oxidized metal atom;
- when M2 is the hydrogen atom or the monovalent metal atom, n is 2;
- and when M2 is the divalent metal atom, the trivalent substituted metal atom, the tetravalent substituted metal atom, or the oxidized metal atom, n is 1;
- and
