PROBLEM TO BE SOLVED: To provide the subject composition having excellent operability and an adhesive performance by containing an organic boron compound, a photopolymerization initiator and a polymerizable monomer mixture. SOLUTION: This composition contains (A) 2-24 pts.wt. of an organic boron compound, (B) 0.002-0.5 pt.wt. of a photopolymerization initiator and (C) 75-97 pts.wt. of a polymerizable monomer mixture containing 2-20wt.% of an acid group-containing monomer. A total of the components (A+B+C) is 100 pts.wt. Furthermore, (D) <=250 pts.wt. of a filler may be added to 100 pts.wt. of the components (A+B+C). Trialkyloxrane is used as the component A, and '- diketones (e.g. (d),(l)-camphorquinone) as the component B and a (meth)acrylate- based monomer, etc., as the component C are respectively used, the composition can be controlled for a hardening speed and can be used for adhesion of a material to be repaired with a dentin or other biological hard tissue. |
