PROBLEM TO BE SOLVED: To provide a new resin composition and its hardened product containing a polycarboxylic acid resin, further to provide a photosensitive resin composition to obtain high resolution, and particularly, to provide a color photosensitive resin composition in which high resolution can be obtained even when a pigment having a small particle size is used in high concentration. SOLUTION: The resin composition contains a polycarboxylic acid resin obtained by preparing a reaction product of (a) an epoxy compound having at least two or more epoxy groups in the molecule with (b) a polybasic carboxylic acid and then further reacting (c) a polybasic carboxylic acid or its anhydride with the above reaction product. |
