The present invention relates to a layered composite material which is characterized in that the composite has at least DOLLAR A a) a polyolefinic carrier layer, DOLLAR A b) an intermediate layer arranged on the carrier layer, which has at least one thermoplastic polymer material, DOLLAR A c) one on the intermediate layer arranged heat-cured layer and DOLLAR A d) comprises a cover layer of thermoplastic plastic arranged on the heat-hardened layer, DOLLAR A wherein the thermoplastic material in the cover layer is selected from the group comprising polycarbonates, acrylic-butadiene-styrene copolymers, poly (butylene terephthalate) e, polyester and derivatives and mixtures of the aforementioned materials. It has surprisingly been found that the layer arrangement or combination of materials according to the invention ensures excellent adhesion between the layers and so the connection of thermoplastic material is selected from the group comprising polycarbonates, acrylic-butadiene-styrene copolymers, poly (butylene terephthalate) s, polyester as well as derivatives and mixtures of the aforementioned materials, with a polyolefin carrier layer. Therefore, the carrier material used in the previously known composite materials with the above-mentioned disadvantageous properties can be completely dispensed with. |
