PURPOSE:To provide the titled composition containing a radically polymerizable monomer and a specific ternary hardener, having high safety in clinical operation, resistant to discoloration, keeping excellent appearance, exhibiting high mechanical strength and giving strong and durable adhesive strength. CONSTITUTION:The objective composition contains (A) 100pts.(wt.) of a radically polymerizable monomer (e.g. monofunctional or bi-tetrafunctional (meth)acrylate with (B) a hardener consisting of (B1) 0.01-10pts. of an organic peroxide (e.g. succinic acid peroxide), (B2) 0.01-20pts. of an alkali metal salt, alkaline earth metal salt or amine salt of an aromatic sulfinic acid (e.g. sodium benzenesulfinate) and (B3) 0.01-20pts. of a barbituric acid derivative [e.g. the compound of formula (R1-R3 are H or residue of aliphatic, aromatic, alicyclic or heterocyclic compound)]. Preferably, the composition is further compounded with 0.1-30pts. of an organic acid, its acid anhydride or a phosphoric acid ester.
