Abstract: A powerful pressure-sensitive adhesive which is notable by way of good wetting and dewetting behaviour on surfaces having different surface energies comprises at least 50 wt %, based on the total weight of the pressure-sensitive adhesive, of at least one polymer A which may be derived from the following monomer composition: a1) 55 to 75 wt % of 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) 20 to 40 wt % of at least one (meth)acrylic ester having an alcohol component based on a linear C1-C18 alcohol; a3) 5 to 15 wt % of acrylic acid. The pressure-sensitive adhesive of the invention reveals particularly good properties when combined with a foamed carrier.
