Abstract

The present invention relates to a thermoplastic multilayer composite of polyamide and polyvinylidene fluoride having adhesive bonding layers and improved resistance to chemical agents such as, for example, methanol-containing fuels. The multilayer composite comprises: PA1 (I): at least one layer comprising a moulding compound of polyamide, PA1 (II): at least one layer adjacent to said layer (I) comprising a moulding compound comprising a mixture of PA2 (a) polyvinylidene fluoride, and PA2 (b) polyglutarimide, wherein the layers (I) and (II) are adhesively bonded to one another.
