Abstract: The invention relates to a block copolymer-containing pressure-sensitive adhesive comprising e) 52% by weight to 65% by weight, preferably 55% by weight to 62% by weight, of an elastomer component, f) 30% by weight to 45% by weight, preferably 35% by weight to 42% by weight, of at least one bonding resin, g) 0% by weight to 15% by weight, preferably to 10% by weight, of at least one softening resin and h) 0% by weight to 18% by weight, preferably to 10% by weight, of further additives, where the elastomer component (a) consists to an extent of at least 90% by weight of polyvinylaromatic-polybutadiene block copolymers, where the polyvinylaromatic-polybutadiene block copolymers include at least one type of diblock copolymer (a1) and at least one type of tri- or multiblock copolymer (a2), the at least one diblock copolymer (a1) has a vinylaromatic content of 15% by weight to 45% by weight, within the elastomer component (a) the proportion of tri- or multiblock copolymer (a2) is between 25% by weight and 50% by weight, preferably between 30% by weight and 45% by weight, the tri- or multiblock copolymer (a2) has a molar mass of at least 125 000 g/mol and a vinylaromatic content of 15% to 45% by weight, and one kind of the tri- or multiblock copolymer is preferably a multi-arm (radial) block copolymer.
