Abstract
The present invention provides a divided redox-curing type composition including 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 second radical monomer including a radical monomer (c) having neither an acidic group nor a hydrophilic group. According to the present invention, a redox-curing type composition capable of securing a time necessary for an adhesion operation and exhibiting high bond strength not only at the initial stage of adhesion but also over a long period of time thereafter in application to a wetting material such as a tooth or a bone as well as a tooth crown repairing material such as a metal or porcelain.
