Abstract:
An adhesive for an at least one-layer pressure sensitive adhesive sheet strip which is residuelessly and nondestructively redetachable by extensive stretching substantially in the bond plane, said adhesive being composed of at least one block copolymer having one or two end blocks composed of vinylaromatics, and a block composed of a conjugated diene, wherein the fraction of 1,2-linked diene is selectively hydrogenated.
