| abstract |
The present invention is a layered composite material useful as a wound treatment article comprising a foam layer (10) and a covering layer (20), wherein the covering layer (20) comprises a thermoplastic polymer (preferably polyurethane). And at least partially directly bonded to the foam layer (10), wherein the foam layer (10) is obtained by foaming and drying the anionic hydrophilized polyurethane aqueous dispersion (I) -containing composition It relates to a layered composite material comprising a foam. The foam can be stabilized using an ethylene oxide / propylene oxide block copolymer. The invention further relates to a method for producing the layered composite material and the use of the layered composite material, for example as a wound treatment article. |
