Curable compositions
Abstract
Abstract A curable composition which contains mono- and poly-functional acrylate monomers and an acidic group-containing acrylate monomer containing at least one acryloyloxy group per molecule, monofunctional acrylamide monomer, trialkylboron and/or partially oxidized product thereof. This composition shows excellent low-temperature curability around ordinary temperature and water-resistant adhesiveness, and exhibits excellent adhesiveness to teeth or dental alloys with less detrimental influences such as stimulation, thus being suited as binding agents for various composite resins. <H0> SUMMARY </H0> A curable composition is provided, comprising a monofunctional (meth)acrylate monomer, a poly functional (meth)acrylate monomer, a (meth)acrylate monomer containing an acidic group and at least one (meth)acryloyloxyl group in its molecule, a monofunctional (meth)acrylamide monomer, and a trialkylboron and/or a partial oxide thereof. The composition has improved low-temperature curability at approximately room temperature and water-resistant adherence, and excellent adhesiveness to tooth substances including enamel and dentin and dental alloys, and gives no adverse influence of stimulation to dental pulp. Most preferably, the composition is used as a bonding agent for dental composite resins.
