The invention relates to a multi-layered wound dressing, particularly for the moist wound treatment, comprising a first layer as a wound contact layer, which contains an aqueous hydrogel matrix, and at least a second absorbing layer. The hydrogel matrix comprises 37 to 43% by weight of propylene glycol, a prepolymer with isophorone diisocyanate groups and a diamine on the basis of polyethylene oxide in an amount of a total of 12 to 16.5% by weight, 0 to 5% by weight of an inorganic chloride, and the remainder water, wherein the ratio of the reactive groups of isocyanate to the amine groups of the diamine should be 1.25 to 1.35.
