27072-125 ABSTRACT A wound dressing comprising (1) a lower layer of a hydrogel of a polymer cross-linked under the influence of electron beam (E.B.) radiation, to which optionally one or more medicinal and/or antibacterial agents and/or one or more auxiliary sub- stances have been added, and (2) a polymeric top layer, in which the top layer consists substantially of an elastomer selected from the group consisting of a silicone rubber, a polyether-polyurethane copolymer, a polyester-polyurethane copolymer, a polyether polyester copolymer and an optionally modified block copolymer based on suitable vinyl monomers. A fibrous layer is provided between the lower layer and the top layer for bonding the two layers together. This elastic textile layer, preferably a fabric made of a polyester, a polyamide or a polyurethane, ensures an excellent bonding between the lower and the top layer combined with excellent elasticity and gas and water vapour permeability of the dressing.
