Abstract: O.Z. 0050/033154 of the disclosure: Binders which comprise (A) an aqueous emulsion of a copolymer A, having a glass transition temperature of 0 - 50.degree.C, of monolefinically unsaturated carboxylic acid esters, with or without styrene, vinyl acetate, vinyl chloride and acrylonitrile, which copolymer contains, as copolymerized units, small amounts of monolefinically unsaturated monocarboxylic acids and/or dicarboxylic acids and/or their amides (of which the nitrogen atoms may or may not be alkyl-substituted and/or alkylol-substituted) and small amounts of monomers containing carbonyl groups, (B) from 0.05 to 1 mole, per mole of carbonyl groups present in the copolymer A, of a water-soluble aliphatic dihydracompound and (C) from 0 to 0.02 mole, per mole of dihydrazine compound, of a water-based zinc, manganese, cobalt and/or lead salt, are particularly suitable for use in paints and pebble dash renderings, since they give films which adhere particularly well to alkyd resin primers and which show particularly little tendency to whitening.
