Although cationic photocurable compositions of the prior art had photocuring properties, the curing process was extremely slow, ultimately making it difficult to obtain cured products that had cured adequately. This photocurable composition contains the components (A) to (D) below, containing more than 0 but not more than 4.5 parts by mass of component (C) with respect to 100 parts by mass of component (A), with component (A) being an oligomer having a hydrolyzable silyl group; component (B) being a photoacid generator; component (C) being water, and component (D) being a compound having one hydroxyl group bonded to a carbon atom within the molecule. The photocurable composition of the present invention is a photocurable composition having delayed photoactivation with which it is possible to obtain adequate curing after a given time has elapsed after irradiation with energy rays, ultimately enabling adequate curing to be achieved and enabling high transparency before and after curing. |
