Acrylic pressure-sensitive adhesive and also adhesive tape furnished with acrylic pressure-sensitive adhesive

An acrylic pressure-sensitive adhesive was to be provided that finds use especially in a reversible adhesive tape that is redetachable without leaving any residue, the adhesive tape having a particularly flat paper backing with high air permeability, and thus gives rise to particularly precise and flat paint edges when applied. This is achieved by an acrylic pressure-sensitive adhesive based on polymers having the following monomer composition: (a) 97% to 99% by weight of monomers from the group comprising 2-ethylhexyl acrylate or 2-octyl acrylate or n-heptyl acrylate or mixtures of at least two of said monomers, (b) 1% to 3% by weight of (meth)acrylic acid
and further comprising a crosslinking system, wherein the ratio of the reactive crosslinking groups and the carboxy groups of (meth)acrylic acid (b) is less than or equal to 7% and wherein the polymers are produced by emulsion polymerization.

The invention also provides an adhesive tape comprising a backing andapplied to at least one side of the backingan acrylic pressure-sensitive adhesive of the invention in the form of a dried polymer dispersion and also the use of such an adhesive tape.
