Abstract: Composite made of two substrates for use for optical, electronic and/or precision-engineered equipment, comprising a first substrate and a second substrate and, arranged so as to connect the first substrate to the second substrate, an adhesive layer, wherein the adhesive layer comprises an adhesive which has, relative to the mixture, (a) from 60% by weight to 90% by weight of a first polymer component based on polyacrylate and (b) from 10% by weight to 40% by weight of a second polymer component based on elastomers, where the second polymer component is essentially not miscible with the first polymer component, so that the adhesive is present in at least two separate phases in the adhesive layer.

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.





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