Abstract
Abstract An adhesive composition comprising, by weight, (1) 100 parts of triglycidyl ether of trisphenol, (2) 0-40 parts of a polyfunctional epoxy resin, (3) a diamine type curing agent selected from (a) an aromatic diamine compound and (b) a reaction product having an amino group at each terminal thereof, prepared by reacting together an aromatic diamine compound, divinylsilane compound and bismaleimide compound, and, if desired, (4) a powdery inorganic filler.
