To provide a polymerizable composition having more excellent preservation stability of pastes than a conventional composition using a combination of a copper compound, cumene hydroperoxide, and N-acetylthiourea, and having a polymerization curing time which does not change with time, that is, does not delay or quicken from a time set for a product even though the composition is stored, the polymerizable composition includes a first paste and a second paste, wherein the first paste includes a polymer of α-β unsaturated monocarboxylic acid or α-β unsaturated dicarboxylic acid, water, and a hydroperoxide as a peroxide, and the second paste includes a (meth)acrylate compound not having an acid group, fluoroaluminosilicate glass powder, a thiourea derivative as a reducing material, and a vanadium compound as a polumerization accelerator. |
