    Abstract: Aqueous dispersions of synthetic resins are obtainable by combining an aqueous starting dispersion of a polymer A which has a glass transition temperature of from -50 to +60 DEG C and is built up from monoethylenically unsaturated monomers which carry, apart from carboxyl groups and derivatives thereof, no further polymerisable or mutually condensable groups, and optionally butadiene, and an aqueous solution of a polymer B which is built up essentially from N-hydroxycarboxymethylamides of acrylic and/or methacrylic acid and/or from water-soluble salts of these N-hydroxycarboxymethylamides, at the beginning, during and/or after completion of the preparation of the aqueous starting dispersion, with the proviso that the solid content of the polymer B, based on the total amount of polymers A and B, is from 0.5 to 10% by weight.
