摘要： An adhesive resin composition comprising an ethylene/vinyl acetate copolymer, a styrene polymer resin, graft-modified polyethylene, a polystyrene elastomer and an ethylene/.alpha.-olefin copolymer in combination is disclosed. This adhesive resin composition shows an excellent adhesiveness between a metal and a thermoplastic resin. When this adhesive resin composition is used for bonding a polyester resin and a gas-barrier resin, a good bonding which is not degraded even by high-temperature heating can be attained.
