PROBLEM TO BE SOLVED: To provide a photocurable composition capable of effectively photocuring a photocurable composition containing a diaryliodonium salt as a photocuring catalyst, and to provide an additive such as a pigment. Provided is a photocurable composition which can be cured in a short time even with a composition containing, and has excellent cured product physical properties. SOLUTION: A diaryliodonium salt derivative acting as a photocationic polymerization catalyst, a hydroxyl group as a substituent, Photocuring from a polycyclic aromatic compound such as a naphthalene derivative or a phenanthrene derivative having at least one aralkyloxy group or an alkoxy group which may be substituted, a thioxanthone derivative, a cationically polymerizable compound and a pigment such as titanium dioxide. An acidic composition is prepared. |
