[Object] To provide a photocurable composition capable of reducing the amount of surface-unpolymerized-products of an obtained cured body and achieving a high photocuring depth, and to provide, particularly, a photocurable composition that can be suitably used in a photocuring-type denture reline material.[Solving Means] A photocurable composition includes: a polymerizable monomer such as 2-methacryloxyethyl propionate and 1,9-nonamethylene methacrylate; resin particles such as spherical poly(ethyl methacrylate) particles; an α-diketone compound such as camphorquinone; a tertiary amine compound such as ethyl p-dimethylaminobenzoate; and an α-hydroxycarboxylic acid having an acid dissociation constant of 3.0 or more in water (at 25° C.) and two or more carbonyl groups in the same molecule, such as malic acid. |
