    • A photopolymerizable dental composition, which comprises:

      (A) an organic composite filler obtained by polymerizing a sulfonic acid or sulfonate monomer of the fomula:
      wherein R₁ is a hydrogen atom, a C₁-C₂₀ alkyl group, a phenyl group or a derivative thereof, or a halogen atom; X is -CONH-,
      -COO(CH or CH wherein each of R₂ and R₃ is a hydrogen atom or a C₁-C₁₅ alkyl group, R₄ is a C₁-C₁₅ alkylene group, m is an integer of from 1 to 20 and n is an integer of from 0 to 20; and Y is a hydrogen atom, NH₄ or an alkali metal atom, and at least one radical polymerizable vinyl monomer in a polymerization system in which an inorganic compound is dispersed;
      (B) a monomer mixture comprising 2,2-bis[4-(methacryloxyethoxy)phenyl]propane, at least one hexa-functional urethane (meth)acrylate of the formula:
      wherein n is an integer of from 1 to 10, and each of R₁ and R₂ which may be the same or different is a hydrogen atom or a methyl group, and a diluting ethylenic vinyl monomer; and
      (C) a photopolymerization initiator comprising an α-diketone compound and a reducing agent, wherein the reducing agent is at least one member selected from the group cosisting of diaminobenzophenone compounds of the formula:
      wherein each of R₁ to R₄ which may be the same or different is a hydrogen atom or a C₁-C₅ alkyl group, provided that at least one of them is the alkyl group, and C₅-C₁₀ alkyl esters of 4-(N,N-dimethylamino)benzoic acid.
