Negative dye-containing curable composition, color filter and method of producing the same
摘要:
The present invention provides a negative dye-containing curable composition comprising at least (A) an alkali-soluble binder, (B) an organic solvent-soluble dye, (C) a photopolymerization initiator, (D) a radical-polymerizable monomer and (E) an organic solvent, wherein the organic solvent-soluble dye (B) comprises at least one kind of azomethine-type dye represented by the following formula (I) and at least one kind of tetraazaporphyrin-type dye represented by the following formula (A), and the photopolymerization initiator (C) is an oxime-type compound, wherein R1 represents a hydrogen atom or a substituent group; R2 to R5 each represent a hydrogen atom or a substituent group, R6 to R7 each represent an alkyl group, alkenyl group, aryl group or heterocyclic group, Za and Zb each represent —N═ or —C(R8)═; R8 represents a hydrogen atom, alkyl group, aryl group or heterocyclic group; M1 represents a metal, and Z1 to Z4 each represent an atomic group forming a 6-membered ring composed of atoms selected from carbon and nitrogen.
