Thermoplastic multilayer composites

In a thermoplastic multilayer composite containing

• at least one intermediate layer made from a molding compound on the basis of ethylene/vinyl alcohol copolymers, between layers made from molding compounds on the basis of polyamide, as well as at least on one side of the intermediate layer an adjacent layer made from a molding compound on the basis of polyamide 12, polyamide 11, polyamide 1010, polyamide 1012, or polyamide 1212,
• the improvement wherein, between the intermediate layer and the at least one adjacent layer, an adhesion-promoting layer is provided which is made from a molding compound on the basis of polyamide selected from the group consisting of copolyamide 6/12 with 60 to 80% by weight of polyamide 6 fraction, block copolyamide 6/12, polyamide 612, polyamide 610, a mixture of polyamide 6 with polyamide 12 and a compatibilizer, and a mixture of polyamide 6 with polyamide 11 and a compatibilizer,
• wherein the quantity of polyamide in the adhesion-promoting layer is at least 60% by weight.
