PURPOSE: To obtain the subject composition keeping excellent adhesive force even at an extremely high temperature by compounding specific amounts of an acrylonitrile-butadiene copolymer and an epoxy resin hardener to a specific resin mixture.
CONSTITUTION: The objective composition is produced by compounding (A) 100 pts.wt. of a resin mixture consisting of (i) 50-85wt.% of a liquid epoxy resin (preferably bisphenol A epoxy resin) and (ii) 50-15wt.% (the sum of (i) and (ii) is 100wt.%) of a polyimide oligodiamine compound (preferably a maleimide compound) with (B) 15-75 pts.wt. of an acrylonitrile-butadiene copolymer and (C) 1-10 pts.wt. of an epoxy resin hardener (preferably a crosslinking hardener active at high temperature) as essential components.
