Abstract (en)
[origin: EP2140888A1] Layer composite comprises a base layer (10), an absorber layer (20) lying on the base layer, and a cover layer (30), where: the cover layer is arranged in such a way that it is connected both to the base layer and also to the absorber layer, and the base layer comprises a polyurethane foam that is obtained by foaming and drying a composition comprising an aqueous, anionically hydrophilized polyurethane dispersion (I). An independent claim is included for the preparation of the layer composite comprising providing the base layer; applying the absorber layer on the basis layer; and applying a further layer, such that this further layer is connected with the basis layer and the absorber layer.
