PROBLEM TO BE SOLVED: To provide a cured product useful as a material such as a coating material, coating agent, a sheet-like material, a sealing material, an adhesive agent, a molding material or casting material and excellent in hardness and heat resistance. SOLUTION: This photocurable composition comprises (A) a silane-modified oligomer obtained from a compound having a hydroxy group and an oxetanyl group and an alkoxysilane and (B) a photocation polymerization initiator having SbF<SB>6</SB><SP>-</SP>, AsF<SB>6</SB><SP>-</SP>or B(C<SB>6</SB>F<SB>5</SB>)<SB>4</SB><SP>-</SP>as an anion and optionally (C) a compound having a group having cation ring-opening polymerization property. The compound (C) is preferably an alicyclic epoxy compound which may contain an aliphatic compound having two oxetanyl groups. COPYRIGHT: (C)2003,JPO
