Aqueous dispersion to be used as adhesive

Abstract

Abstract Adhesive includes aromatic emulsifier and alkyl acrylate based polymer dispersion. Adhesive comprises a polymer dispersion and an emulsifier containing ≥ 5 wt.% aromatic carbon atoms, or an emulsifier mixture comprising ≥ 10 wt.% emulsifier. The polymer comprises: (i) 60-95 wt.% of a mixture of a 4 C alkyl acrylate and 6-12 C alkyl acrylate; (ii) 5-30 wt.% ethylenically unsaturated compounds with Tg 0 degrees C; (iii) 0-10 wt.% ethylenically unsaturated compounds with an acid or acid anhydride; and (iv) 0-20 wt.% further ethylenically unsaturated compounds. Independent claims are also included for an aqueous polymer dispersion comprising a polymer, and labels or adhesive tape coated with the adhesive.
