A composite article of a massive carrier layer of a polyester material which can comprise up to 50% by weight of another polymer material which is compatible with it, and if appropriate up to 50% by weight of reinforcing and/or filling additives and other auxiliaries, and a decorative layer, which is built up, if appropriate, from several layers of materials which influence the visual properties and/or haptic properties and which all essentially comprise polyester material, the carrier layer of which is anchored undetachably in the contact area with the layer of material of the decorative layer which is in contact with it, the layers of the composite article in their entirety having a composition such that a homogeneous mixture of the same composition can be employed again to produce a structural element of plastic which has adequate mechanical data, is described. A process for the production of these composite articles furthermore is described.
