PROBLEM TO BE SOLVED: To provide a photosensitive composition that allows formation of a cured product excellent in release property from a mold, adhesiveness to a plastic substrate and transparency.SOLUTION: The photosensitive composition comprises the following components (1) to (4): (1) a radical initiator (A), (2) an acid generator (B) and/or a base generator (C), (3) a polymerizable substance (D), and (4) a salt (G) comprising a phosphate (a) having a specified composition and a tertiary amine (b). In the composition, at least one of the radical initiator (A), the acid generator (C) and the base generator (C) generates an active species (H) by irradiation with active rays; (H) reacts with (A), (B) or (C) to generate a new active species (I), and (I) promotes a polymerization reaction of the polymerizable substance (D). (H) or (I) is an acid or base. (D) contains a UV-curable resin (D1) having a specified molecular weight and a (meth)acrylate (D2) having a specified molecular weight. The photosensitive composition does not substantially contain any of a colorant, a metal oxide powder and a metal powder. |
