摘要：
The use of an aqueous polyurethane dispersion adhesive is described for producing biodisintegratable composite foils where at least two substrates are adhesive-bonded to one another with use of the polyurethane dispersion adhesive, where at least one of the substrates is a biodisintegrable polymer foil. At least 60% by weight of the polyurethane is composed of diisocyanates, polyesterdiols, and at least one bifunctional carboxylic acid selected from dihydroxycarboxylic acids and diaminocarboxylic acids.
