Abstract

Disclosed is a curable electromagnetic shielding adhesive film having a curable conductive polyurethane-polyurea adhesive layer (I) and a curable insulating polyurethane-polyurea resin composition layer (II). The curable conductive polyurethane-polyurea adhesive layer (I) contains a polyurethane-polyurea resin (A) which is obtained by reacting a urethane prepolymer (a4) having an isocyanate group at an end with a polyamino compound (a5), and an epoxy resin (B) having two or more epoxy groups. The urethane prepolymer (a4) is obtained by reacting a carboxyl group-containing diol compound (a1), a polyol (a2) having a number average molecular weight of 500-8,000 which is not a carboxyl group-containing diol compound, and an organic diisocyanate (a3). The curable conductive polyurethane-polyurea adhesive layer (I) also contains 10-700 parts by weight of a conductive filler per 100 parts by weight of the total of the polyurethane-polyurea resin (A) and the epoxy resin (B). The curable insulating polyurethane-polyurea resin composition layer (II) contains a polyurethane-polyurea resin (C) which is obtained by reacting a urethane prepolymer (c4) having an isocyanate group at an end with a polyamino compound (c5), and an epoxy resin (D) having two or more epoxy groups. The urethane prepolymer (c4) is obtained by reacting a carboxyl group-containing diol compound (c1), a polyol (c2) having a number average molecular weight of 500-8,000 which is not a carboxyl group-containing diol compound, and an organic diisocyanate (c3).
