The present invention provides a photocured product having both excellent toughness and high strength, and also provides a photocurable composition for forming said photocured product. The present invention provides a photocurable composition comprising: A. a (meth)acrylic acid ester monomer, wherein the glass transition temperature of a polymer formed from only said monomer is 20°C or higher; B. a polyrotaxane obtained by respectively placing blocking groups at both ends of a pseudo-polyrotaxane, which is obtained by threading a linear molecule through the hole of a cyclic molecule, so as not to release the cyclic molecule, wherein the cyclic molecule has a (meth)acrylic group; and C. a photopolymerization initiator. The present invention also provides a photocured product formed from said composition. |
