  • Patent number: 7504443
    Abstract: The dental adhesive composition of the present invention comprises a polyfunctional polymerizable monomer which is an ester compound of a polyhydric alcohol of 3 to 6 carbon atoms and plural (meth)acrylic acids and has 1 to 2 hydroxyl groups, a monofunctional (meth)acrylate having no hydroxyl group in its molecule, a polymerizable monomer containing an acid group in its molecule, an organoboron compound as a curing agent and a filler. According to the present invention, a dental adhesive composition remarkably enhanced in the curing rate with rarely affecting adhesion properties of the composition, working time and flexibility of a cured product is provided.
    Type: Grant
