摘要：The invention relates to an extensively biologically degradable adhesive tape,which in particular has a good and quickly established anchoring between the adhesiveand the carrier. The invention relates to an adhesive tape for protecting surfaces,comprising an adhesive H, containing at least 60 wt %, at least one polyurethane P,obtainable from chemical cross-linking of a polyurethane pre-polymer, obtainable fromthe chemical reaction of d) one or a plurality of aliphatic polyester polyols A having ahydroxy functionality of 1.8 through 2 and a number-averaged molecular weight of equalto/greater than 1,000 g/mole; e) one or a plurality of compounds B having a hydroxyfunctionality of 1.8 through 2 and a number-averaged molecular weight of less than 1,000g/mol; f) one or a plurality of aliphatic diisocyanates C; wherein the ratio of the totalnumber of isocyanate groups to the total number of hydroxy groups of the substancesinvolved in the chemical reaction for building the prepolymer is greater than/equal to 0.4and less than 1; and a biodegradable carrier.
