PURPOSE:To obtain a dental adhesive containing a specific chlorinated solvent and a polycarbonate resin at a specific ratio, and capable of bonding a dental polysulfone resin firmly to a dental acrylic resin. CONSTITUTION:An adhesive containing (A) 100pts.wt. of a chlorinated solvent having a boiling point of 50-150 deg.C (e.g. ethylene chloride, chloroform, trichloroethylene, etc.) and (B) 0.3-20pts.wt., preferably 0.5-15pts.wt. of a polycarbonate resin (i.e. 4,4-dioxydiarylalkane polycarbonate) is used for the bonding of a dental polysulfone resin and a dental acrylic resin, e.g. bonding of a denture bed made of polysulfone resin and an artificial tooth made of an acrylic resin, a denture bed made of a polysulfone resin and a rebasing agent composed of an acrylic resin, a denture bed made of acrylic resin and an artificial tooth made of polysulfone resin, etc.
