A pressure-sensitive adhesive for bonding to various surfaces, such as metals, plastics, and also vehicle finishes, with rapid wetting and high adhesion, with good shear strengths and bond strengths under different conditions and without undergoing dewetting even under lasting mechanical load, comprises: a) at least 50 wt % of at least one polymer A whose monomer basis comprises the following monomers: a1) at least one (meth)acrylic ester having a homopolymer glass transition temperature of not more than −60° C. and an alcohol component based on a branched, primary alcohol, having an iso index of 1; a2) at least one (meth)acrylic ester having an alcohol component based on a linear C.sub.1-C.sub.18 alcohol; a3) acrylic acid; b) at least 5 wt % of at least one synthetic rubber; and c) at least 10 wt % of at least one peel adhesion-reinforcing resin.

Also disclosed is an adhesive tape comprising a foamed carrier and the pressure-sensitive adhesive.

The invention relates to a pressure-sensitive adhesive strip composed of at least three layers, comprising an inner layer F composed of a non-extensible film carrier, a layer SK1 composed of a self-adhesive composition arranged on one of the surfaces of the film carrier layer F and based on a vinylaromatic block copolymer composition foamed with microballoons, a layer SK2 composed of a self-adhesive composition arranged on the opposite surface of the film carrier layer F from the layer SK1 and based on a vinylaromatic block copolymer composition foamed with microballoons, where the mean diameter of the voids formed by the microballoons in the self-adhesive composition layers SK1 and SK2 is independently 20 to 60 m.
