Abstract: Novel pressure-sensitive aqueous adhesive dispersions comprising 40 to 65% by weight, based on the dispersion weight, of a copolymer produced by radical emulsion polymerization of ethylene, vinyl esters of saturated carboxylic acids of 2 to 12 carbon atoms, ethylenically unsaturated carboxylic acids, ethylenically unsaturated hydroxyalkyl functional compounds, optionally present (meth)acrylic acid esters with alkyl of 4 to 12 carbon atoms and optionally present mono- or poly-ethylenically unsaturated compounds having a second order transition temperature of -20.degree. to -60.degree. C. and a K value of 50 to 180, characterized in that the copolymer was obtained by polymerization of(a) 10-45% by weight of ethylene(b) 0-25% by weight of acrylic ester(s)(c) 40-89% by weight of vinyl ester(s)(d) 0.5-4% by weight of ethylenically unsaturated carboxylic acids(e) 0.5-10% by weight of ethylenically unsaturated hydroxyalkyl-functional compounds(f) 0-0.
