Claim:
A divided redox-curing type composition comprising: a first part in which at least an oxidizing agent (b) is dissolved in a first radical monomer including a radical monomer (a) having an acidic group and/or a hydrophilic group; and a second part in which at least an aromatic sulfinate (d) is dispersed in a powder form in a second radical monomer comprising at least one radical monomer (c) having neither an acidic group nor a hydrophilic group selected from the group consisting of 2,2-bis[4-(meth)acryloyloxypolyethoxyphenyl]propane, neopentyl glycol di(meth)acrylate, N,N′-(2,2,4-trimethylhexamethylene)bis[2-(aminocarboxy)propane-1,3-diol]tetra(meth)acrylate and 1,10-decanediol di(meth)acrylate.
