Abstract
A curable composition is provided, comprising a monofunctional (meth)arcylate 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.
