    • A biodegradable pressure-sensitive adhesive is to be provided, additionally having the particular feature of good shear strength at relatively high temperatures. This is achieved by the chemical crosslinking of a polyurethane prepolymer obtainable by the chemical reaction of a) one or more aliphatic polyester polyols A having a hydroxyl functionality of 1.8 up to and including 2 and a number-average molecular weight of greater than/equal to 1000 g/mol; b) one or more compounds B having a hydroxyl functionality of 1.8 up to and including 2 and a molecular weight of less than 1000 g/mol; and c) one or more aliphatic diisocyanates C, where the ratio of the total number of isocyanate groups to the total number of hydroxyl groups in the substances involved in the chemical reaction is greater than/equal to 0.4 and less than 1; and by the formulation of a pressure-sensitive adhesive having one or more polyurethane(s) of this kind as the main constituent.
