ABSTRACT:
A two part curable adhesive composition for use as adhesive for dental composite resin is provided, as a first part (i) a solution comprising a radical polymerizable acrylate or methacrylate monomer having in its molecule at least one group selected from the group consisting of hydroxyalkyl, hydroxyalkylene, amide, oxyalkylene and polyoxyalkylene groups, and a colvent for said radical polymerizable acrylate or methacrylate monomer; and as a second part (ii) a curable composition comprising (P) a monofunctional acrylate or methacrylate monomer, (Q) a polyfunctional acrylate or methacrylate monomer, (R) an acrylate or methacrylate monomer containing an acidic group and at least one acryloyloxyl or methacryloyloxyl group in its molecule, and (S) a trialkylboron or an oxide thereof; wherein said component (S) is maintained separate from said components (P), (Q) and (R) until immediately before use. A method for applying the above-described two-part curable adhesive composition to a dental area is provided, comprising: dissolving said radical polymerizable acrylate or methacrylate monomer in said solvent to form said solution (i); applying said solution (i) to a dental area; removing said solvent from said applied solution to form a coated area; mixing said components (P), (Q) and (R) with said component (S) to form said composition (ii); applying said composition (ii) to said coated area immediately after mixing to form a coating, and curing said coating.
