Aq. organic-solvent-free adhesives contain a mixed polymer of acrylic acid, vinyl acetate and at least one copolymerisable monomeric tenside chosen from a) polyoxyethyleneallylalcohol (polyoxyethyleneglycolallylether) of formula H2C=CH-CH2-(-O-CH2-CH2-)n-OH (IA) or a methyl ether of formula H2C=CH-CH2-(-O-CH2-CH2-)n-O-CH3 (IB), where n = 4-24; b) methoxy-polyethyleneglycol methacrylates of formula H2C=C(CH3)-C(O)-(-O-CH2-CH2-)n-O-CH3 (II), where n = 2-50; c) ethoxylated hydroxyethylmethacrylates of formula H2C=C(CH3)-C(O)-(-O-CH2-CH2-)n-O-CH2-CH2-OH (III) where n = 2-50; d) mono(methacryloyloxyethyl) phosphoric acid esters of formula H2C=C(CH3)-C(O)-O-CH2-CH2-O-P(O)(OH)-OH (IV), and/or its salt; e) an ammonium salt of methacrylbyloxyethylsulphuric acid of formula H2C=C(CH3)-C(O)-O-CH2-CH2-O-SO3-NH4 (V); f) polyethylene glycolconc. acrylates and/or methacrylates with 2-50 oxyethylene gps. per molecule, and g) polypropylene glycol monoacrylates and/or methacrylates with 2-50 oxypropylene gps. per molecule.
