PROBLEM TO BE SOLVED: To obtain a photosensitizer-containing curable composition having high sensitivity to a long-wavelength laser beam in the visible region and excellent storage stability by mixing a photocurable resin with a photoreaction initiator, a radical protecting compound, and a photosensitizer containing a pyrrole compound. SOLUTION: This composition comprises a radical protecting compound selected from a phosphorous ester compound and an aromatic compound having an N,N-dimethylamino group bonded to a carbon atom constituting the aromatic ring and a photosensitizer containing a pyrrole compound represented by the formula. In the formula, R1 is H, a 1-20C alkyl, a hydroxyalkyl, an alkoxyalkyl, an alkoxycarbonylalkyl, an aryl, an aralkyl, or an alkenyl; and R2 to R10 are each H, a halogen, nitro, cyano, hydroxyl, amino, aminocarbonyl, carboxyl, sulfo, a 1-20C alkyl, a halogenoalkyl, an alkoxyalkyl, an alkoxyl, or the like. |
