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.

Abstract: The presently claimed invention relates to use of an aqueous polymer latex as a binder or co-binder in a waterborne coating composition, wherein the aqueous polymer latex is obtained by polymerizing a monomer composition M, comprising at least one tert-butyl acrylate and/or tertbutyl methacrylate monomer, by radical emulsion polymerization.
