Abstract: 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.

Abstract: The invention relates to a rim insert system for a rim having at least one opening which forms a rim channel that tapers in a funnel-like manner, and at least one funnel-like rim insert releasably engaged in the opening. The rim insert has a peripheral catch edge which engage behind an internally arranged opening edge of the rim channel in an inserted position. A first catch projection is in abutment with an inclined portion of the opening edge. The inclined portion and the inner face of the rim channel are disposed at an angle of approximately from 200°-240° in cross-section. A second catch projection is substantially diametrically opposed to the first catch projection and engages behind the opening edge in a positive-locking manner. The inner face of the rim channel and the opening edge form an angle of approximately from 270° to 290°.
