Beschreibung
Zusammenfassung:	A polyurethane adhesive composition, which comprises an organic polyisocyanate, a polyol, an oxyacid of phosphorus or a derivative thereof, an epoxy resin and a silane coupling agent. The polyurethane adhesive composition, when used as an adhesive for packaging materials for food, provides the bond showing outstandingly excellent adhesion strength, heat resistance and hot-water resistance between metal foil such as aluminum foil and films of plastics such as polyethylene, polypropylene, nylon and polyethylene terephthalate etc.
