(57) [Abstract] [Purpose] To provide a novel photosensitive resin composition having excellent heat resistance and chemical resistance, and to provide a resist ink composition having an excellent balance of various properties by applying the same. . [Structure] The present invention comprises 2) a) (1) carboxylic acid anhydride group. One or more compounds, (2) a compound having 0.1 to 1.0 equivalent of a primary and / or secondary amine and a radically polymerizable group with respect to the carboxylic acid anhydride group, and (3) the carboxylic acid A photosensitive resin obtained by reacting 0.0 to 0.9 equivalents of an active group other than primary or secondary amines with an anhydride group and a compound having or not having a radical polymerizable group, and B). A photosensitive resin composition containing a polymerization initiator as an essential component. |
