Patent ID: 7846622

Claim:
An alkali-developable, colored photosensitive resin composition obtained by adding (E) a colorant and (F) a photopolymerization initiator to an alkali-developable resin composition, the alkali-developable resin composition containing a reaction product obtained by esterification between an epoxy adduct and (D) a polybasic acid anhydride, the epoxy adduct having a structure formed by adding (B) an unsaturated monobasic acid and (C) a compound selected from a phenol compound, an alcohol compound, an amine compound, and a carboxylic acid to (A) an epoxy resin represented by general formula (I) shown below, the epoxy adduct having a structure formed by adding 0.1 to 1.0 carboxyl group of the unsaturated monobasic acid (B) and 0 to 0.9 phenolic hydroxyl group, alcoholic hydroxyl group, amino group or carboxyl group of the compound (C) per epoxy group of the epoxy resin (A), with the sum of the carboxyl group of the unsaturated monobasic acid (B) and the phenolic hydroxyl group, alcoholic hydroxyl group, amino group or carboxyl group of the compound (C) being 0.1 to 1.0 per epoxy group, and the esterification being carried out at a ratio of 0.1 to 1.0 anhydrous structure of the polybasic acid anhydride (D) per hydroxyl group of the epoxy adduct wherein Cy represents a cycloalkyl group having 3 to 10 carbon atoms; X represents a hydrogen atom, a phenyl group which may be substituted with an alkyl group having 1 to 10 carbon atoms or an alkoxy group having 1 to 10 carbon atoms, or a cycloalkyl group having 3 to 10 carbon atoms; Y and Z each represent an alkyl group having 1 to 10 carbon atoms, an alkoxy group having 1 to 10 carbon atoms, an alkenyl group having 2 to 10 carbon atoms or a halogen atom; the alkyl group, the alkoxy group, and the alkenyl group may be substituted with a halogen atom; n represents a number of 0 to 10; p represents a number of 0 to 5; and r represents a number of 0 to 4.
