Abstract
Disclosed is an adhesive composition comprising (a) 100 parts by weight of a monomer mixture comprising a vinyl monomer having an acidic group in the molecule and a vinyl monomer copolymerizable with said vinyl monomer, (b) 10 to 500 parts by weight of a filler, (c) 0.01 to 10 parts by weight of a polymerization initiator and (d) 0.01 to 10 parts by weight of ascorbic acid or a derivative thereof. This adhesive composition has a high bonding force and an excellent durability even in a severe environment, for example, in the environment in the oral cavity. Accordingly, this adhesive composition is especially valuable used as a dental adhesive.
