This invention provides an adhesive composition which comprises 1 part by weight of (a) a compound of the general formula: ##STR## wherein R 1 represents H, a hydrocarbon group of 1-6 carbon atoms optionally containing halogen, COOR', wherein R' represents a hydrocarbon group of 1-20 carbon atoms op
This invention provides an adhesive composition which comprises 1 part by weight of (a) a compound of the general formula: ##STR## wherein R 1 represents H, a hydrocarbon group of 1-6 carbon atoms optionally containing halogen, COOR', wherein R' represents a hydrocarbon group of 1-20 carbon atoms optionally containing halogen or halogen; R 2 is as defined for R 1 ; R 3 represents H, a hydrocarbon group of 1-6 carbon atoms optionally containing halogen, halogen or CN; R 4 represents (COX 2 ) m1 (CO) m2 (ZCO) m3 (Z) m4 Ra wherein Ra represents an organic residue of 6-60 carbon atoms and a valency of m+n ; m1, m2, m3 and m4 each represents an integer of 0-4 and satisfies m1+m2+m3+m4≤m; X 2 represents O, S or NRb, (wherein Rb represents H or alkyl of 1-4 carbon atoms and Z represents O or S; X 1 is as defined for X 2 ; m is an integer of 1-4; n is an integer of 2-6; and k is 0 or 1, and 0-199 parts by weight of (b) a vinyl monomer copolymerizable with the aforesaid compound. Such an adhesive composition can strongly adhere to any of the hard tissues of the living body, such as teeth and bones, metal materials, organic polymer materials and ceramic materials, and, in particular, has an advantage in that it can maintain high adhesive strength for a long time under wet conditions. While the adhesive composition of this invention may be used in various fields, it is especially useful in the dentistry field.
