PROBLEM TO BE SOLVED: To provide a photocuring composition capable of efficiently photocuring photocurable compositions containing a diaryliodonium salt derivative or triarylsulfonium salt derivative as a photocuring catalyst, and to provide a photocurable composition capable of being quickly cured even when containing additives such as a pigment and giving cured products having excellent physical properties. SOLUTION: This photocurable composition comprises a diaryliodonium salt derivative or triarylsulfonium salt derivative acting as a photocation polymerization catalyst, a compound having a cation polymerizable group and a sensitizer accelerating a photocation initiation reaction, a cation polymerizable compound, and a pigment such as titanium dioxide. |
