    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.

    Abstract: The invention relates to an adhesive strip which can be detached substantially on the adhesion plane in a residue-free and nondestructive manner by stretching, said strip consisting of one or more adhesive material layers and optionally one or more intermediate carrier layers, at least one of the adhesive materials layers containing at least one filler, the primary particles of which can be individually separated, wherein the primary particles (i) are substantially spherical and (ii) have an average diameter d(0.5) of less than 10 μm, and the ratio of the average diameter d(0.5) of the primary particles to the thickness of the adhesive material layer in which the primary particles are contained is less than 1:2. The invention also relates to the production and use of said adhesive strip.
