摘要: The invention relates to the use of an aqueous polyurethane dispersion adhesive for producing biologically disintegratable composite films, wherein at least two substrates are glued to each other using the polyurethane dispersion adhesive, wherein at least one of the substrates is a biologically disintegratable polymer film. The polyurethane is made up to at least 60 wt % of diisocyanates, polyesterdiols, and at least one bifunctional carboxylic acid selected from dihydroxycarboxylic acid and diaminocarboxylic acid.
