Abstract:
A method for producing biodisintegratable composite foils with an aqueous polyurethane dispersion adhesive. The method involves adhesive-bonding a first substrate to a second substrate with use of the aqueous polyurethane dispersion adhesive. At least one of the first substrate and the second substrate is made of a biodisintegratable polymer foil, and at least 60% by weight of the polyurethane contains diisocyanates, polyesterdiols, and bifunctional carboxylic acids. The bifunctional carboxylic acids are dihydroxycarboxylic acids or diaminocarboxylic acids.
