    摘要： A multilayer film containing layers of polyamide and polyester, suitable as a back cover for a photovoltaic module is provided. The film comprises, in the order listed: a) a layer which comprises at least 35% by weight of polyamide; c) a layer which comprises at least 35% by weight, of a thermoplastic polyester; and e) a layer which comprises at least 35% by weight of polyamide; wherein the layers a) and e) further comprise 0.1 to 60% by weight, of a polyamine-polyamide graft copolymer, or the layer c) further comprises 0.1 to 30% by weight of polyamine-polyamide graft copolymer. The polyamine-polyamide graft copolymer comprises as copolymerized monomers: a polyamine having at least 4 nitrogen atoms and at least one polyamide-forming unit selected from the group consisting of a lactam, an ω-aminocarboxylic acid and an equimolar combinations of a diamine and a dicarboxylic acid. In another embodiment, adhesion promoting layers are placed between the layers.
