ABSTRACT:
An adhesive composition comprises 100 parts by weight of a polymerizable monomer comprising (a) 1.5 to 50 parts by weight of a compound represented by general formula I or II: ##STR1## where R.sub.1 and R.sub.1 ' each stand for hydrogen or a methyl group, R.sub.2 stands for a divalent organic residue having 4 to 40 carbon atoms, X.sub.1 and X.sub.2 each stand for --O--, --S-- or --NH--, a is 0 or 1, and R.sub.3 stands for a group of the formula ##STR2## having 6 to 40 carbon atoms, where R.sub.4 and R.sub.4 ' each stand for a hydrocarbon group having 1 to 29 carbon atoms, and optionally replaced by a halogen atom, or a hydroxyl, amino or carboxyl group, b is an integer of 0 to 3, and Z stands for --O--, --COO-- or --NH--, a plurality of R.sub.4 ' (when b is 2 or 3) being the same or different, at least one of R.sub.4 and R.sub.4 ' having at least three carbon atoms, and (b) 50 to 98.5 parts by weight of a vinyl monomer copolymerizable with the above compound; and 0.01 to 20 parts by weight of a curing agent. It shows a superior adhesive strength on any of hard tissues in a living body, such as teeth and bones, metals, organic polymers and ceramics. It maintains a high adhesive strength for a long time even if it is exposed to moisture, or immersed in water. It is particularly effective for use in dentistry, though it is useful for a variety of other purposes, too.
