Abstract
PURPOSE:To obtain the titled material composed of a radically polymerizable monomer and a photo-polymerization initiator and having improved photo- polymerizability, storage stability, color tone, etc., by using an alpha-ketocarbonyl compound (a photosensitizer) in combination with a specific naphthalene compound (a reducing agent) as the photo-polymerization initiators. CONSTITUTION:The objective photo-polymerizable dental material is composed of (A) a radically polymerizable monomer and (B) a photo-polymerization initiator comprising (a) an alpha-ketocarbonyl compound as a photo-sensitizer and (b) a reducing agent selected from the compound of formula I [R2 is H, alkyl, hydroxyalkyl or cyanoalkyl; R3 is OH, NH2, NHNH2, halogen or group of formula II; R4 is H or (CH2)nCH3 (alkyl may be substituted with phenyl); n is 0-5] as a reducing agent. The photo-polymerization of the dental material sufficiently proceeds by the photo-irradiation for a short period even at a low- temperature region near room temperature and the material has excellent storage stability, color tone, etc. Accordingly, the present photo-polymerizable dental material is useful as a dental composite resin or hard resin for tooth.
