Abstract
This invention discloses a dental adhesive composition comprising (A) a polymerizable monomer comprising an acidic-group containing polymerizable monomer such as 11-methacryloyloxy-1,1-undecane dicarboxylic acid, (B) a mixed filler of a spherical filler substantially consisting of a non-crosslinking polymethyl methacrylate and a spherical filler substantially consisting of a non-crosslinking polyethyl methacrylate; and (C) a polymerization initiator; and a dental adhesive kit comprising the above dental adhesive composition in combination with a dental primer comprising (D) an acidic-group containing polymerizable monomer, (E) an aryl borate, (F) an organosulfinic acid salt and (G) water. The dental adhesive composition exhibits good operability and improved adhesion performance.
