PURPOSE:To titled composition having improved photopolymerization curing properties, and extremely high bond strength to the teeth, obtained by using a benzyl sulfone compound as a photopolymerization initiator and a photopolymerizable monomer. CONSTITUTION:A photopolymerizable monomer[e.g., tri-(2-methacryloxyethyl) pyrophosphoric ester, etc.] is blended with an alpha-diketone (e.g., benzil, etc.) as a photopolymerization initiator and an amine(e.g., N,N-dimethylaminoethyl methacrylate, etc.) to give a photopolymerizable resin, which is blended with 0.5-5wt% based on the photopolymerizable monomer of a benzyl sulfone com pound (e.g., benzylsulfinic acid methyl ester, etc.), to give a dental photopolymerizalbe composition.
