PROBLEM TO BE SOLVED: To quickly cure by irradiating with active energy rays, to have good coating film hardness after curing, and to improve adhesion to a substrate, solvent resistance, thermal stability, and tackiness. To provide an excellent photosensitive resin composition. SOLUTION: At least one unsaturated monocarboxylic acid containing an unsaturated monocarboxylic acid (a1) obtained by reacting a compound having at least two ethylenically unsaturated bonds and hydroxyl groups in one molecule with an acid anhydride A photosensitive resin composition containing a prepolymer (A1) obtained by reacting an acid with an epoxy compound (b) having at least two epoxy groups in one molecule. |
