Abstract
This invention provides an adhesive composition which comprises 1 part by weight of (a) a compound of the general formula: ##STR1## wherein R.sub.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; PA1 R.sub.2 is as defined for R.sub.1 ; PA1 R.sub.3 represents H, a hydrocarbon group of 1-6 carbon atoms optionally containing halogen, halogen or CN; PA1 R.sub.4 represents (COX.sub.2).sub.m1 (CO).sub.m2 (ZCO).sub.m3 (Z).sub.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.ltoreq.m; X.sub.2 represents O, S or NRb, (wherein Rb represents H or alkyl of 1-4 carbon atoms and Z represents O or S; PA1 X.sub.1 is as defined for X.sub.2 ; PA1 m is an integer of 1-4; PA1 n is an integer of 2-6; and PA1 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 …
