Beschreibung
Zusammenfassung:	The invention concerns a metal laminate comprising between two outer metal sheets an adhesive polymer layer, characterized in that the adhesive polymer layer comprises polyamide, a copolymer of ethylene and an unsaturated carboxylic acid and/or a derivative thereof and a reactive copolymer. The invention further concerns a process for the manufacture of such a metal laminate and the use of such metal laminates for the manufacture of automotive body parts. La présente invention se rapporte à un stratifié métallique comportant entre deux feuilles métalliques externes une couche polymère adhésive, caractérisé en ce que la couche polymère adhésive comporte un polyamide, un copolymère éthylène et acide carboxylique insaturé et/ou son dérivé et un copolymère réactif. L'invention se rapporte également à un procédé de fabrication d'un stratifié métallique de ce type et à l'utilisation de stratifiés métalliques de ce type dans la fabrication de pièces de carrosserie automobile.
