Claims
- 1. An adhesive composition comprising:
- (A) at least one cyanate ester compound selected from the group consisting of:
- (i) polyfunctional aromatic cyanate ester monomers having the formula
- R--O--C.tbd.N).sub.n
- wherein n is integer of 2-10 and R is an aromatic organic group, the cyanate groups being bonded to an aromatic ring or said aromatic organic group;
