摘要
A photocurable composition is provided which yields an excellent tack-free, hard cured product without any addition of photoinitiators. A photocurable composition which is excellent in storage stability is also provided. The photocurable composition contains a resin having an acryloyl group and a chemical structure element selected from the group consisting of β-diketone groups and β-ketoester groups, wherein the β-diketone group or the β-ketoester group has a tetra-substituted carbon atom between two carbonyl groups, which is capable of generating one or two free radicals under photoirradiation, and the photocurable composition does not increase more than 25% in viscosity when heated at 60°C for 5 days.
