ABSTRACT:
An adhesive which comprises (a) 1 part by weight of a polymerizable monomer represented by the formula ##STR1## (where R.sub.1 denotes H or CH.sub.3 ; R.sub.a denotes a C.sub.6-40 organic residue having a valence of m+1; X.sub.1 and X.sub.2 denote O, S, or NR' [where R' denotes H or a C.sub.1-6 hydrocarbon group], two of X.sub.1 may be different from each other when m is 2; Z denotes a halogen; and m is 1 or 2 and k is 0 or 1), and (b) 0 to 199 parts by weight of monomer which is copolymerizable with said monomer (a).
This adhesive firmly adheres to hard tissues of the living body such as teeth and bones, metallic materials, organic polymeric materials, and ceramics. It keeps the high adhesive strength for a long period of time under a wet condition. This adhesive is useful particularly in dentistry.
