Abstract: An aqueous polymer latex obtainable by polymerizing, optionally in the presence of a seed latex, a monomer composition M by radical emulsion polymerization, wherein the monomer composition M comprises, based on the total weight of the monomer composition M: a) 0.5 to 30% by weight of 2-octyl acrylate, b) 25 to 55% by weight of n-butyl acrylate, c) 35 to 65% by weight of methyl methacrylate, d) 0 to 5% by weight of one or more monoethylenically unsaturated carboxylic acids, e) 0 to 5% by weight of one or more monoethylenically unsaturated carboxylic acid amides, f) 0 to 10% by weight of one or more further ethylenically unsaturated non-ionic monomers different from monomers a), b), c), d) and e).

Abstract: Described is a pressure-sensitive adhesive composition in the form of an aqueous polymer dispersion comprising a dispersed pressure-sensitive adhesive polymer formed by emulsion polymerization of isobutyl acrylate, 2-ethylhexyl acrylate and/or 1-octyl acrylate and styrene, monomers having at least one acid group and optionally further monomers. The pressure-sensitive adhesive composition may be used to produce self-adhesive articles such as self-adhesive labels, self-adhesive tapes or self-adhesive films.
