    Abstract: The invention relates to a pressure-sensitive adhesive strip containing at least one layer SK1 of a self-adhesive composition based on vinylaromatic block copolymer and containing tackifying resin, wherein the vinylaromatic block copolymer contains at least one polymer block A formed predominantly by polymerization of vinylaromatics, and simultaneously contains at least one polymer block B formed predominantly by polymerization of conjugated dienes, where the proportion of 1,2-bonded conjugated diene in the B block is less than 30% by weight, preferably less than 20% by weight. The invention also relates to a pressure-sensitive adhesive strip of this kind, in which at least layer SK1 has been subjected to irradiation with electrons.
