Abstract
An alkali-developable, colored photosensitive resin composition obtained by adding a colorant and a photopolymerization initiator to an alkali-developable resin composition, containing a reaction product obtained by esterification between an epoxy adduct and a polybasic acid anhydride, the epoxy adduct having a structure formed by adding an unsaturated monobasic acid and a compound selected from a phenol compound, an alcohol compound, an amine compound, and a carboxylic acid to an epoxy resin represented by general formula. The epoxy adduct is formed by adding 0.1 to 1.0 carboxyl group of the unsaturated monobasic acid and 0 to 0.9 phenolic hydroxyl group, alcoholic hydroxyl group, amino group or carboxyl group per epoxy group of the epoxy resin, with the sum of the carboxyl unsaturated monobasic acid and the phenolic hydroxyl group, alcoholic hydroxyl, amino or carboxyl group being 0.1 to 1.0 per epoxy group.
