PHOTOCURABLE COMPOSITION, DENTAL PLATE LINER, AND KIT FOR PREPARING THESE

WIPO Patent Application WO/2020/059399

A1

[Problem] To provide a photocurable composition capable of lowering the amount of unpolymerized product at a surface of an obtained cured body and achieving a high photocuring depth; and in particular to provide a photocurable composition able to be advantageously used in a photocuring type dental plate liner. [Solution] This photocurable composition contains polymerizable monomers 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 which has two or more carbonyl groups in the same molecule and has an acid dissociation constant of 3.0 or more in water (at 25°C), such as malic acid.
