Date Jul. 10, 1997The invention relates to dispersion-powder compositions redispersible in water and containing (a) a vinyl ester ethylene copolymer with 50 to 90% by weight of vinyl esters of C2 to C12 carboxylic acid, 1 to 30% by weight of ethylene, 0-20% by weight of vinyl esters of alpha -branched monocarboxylic acids with 5 to 10 C-atoms, each in relation to the total weight of the vinyl ester ethylene copolymer, and (b) a water soluble copolymer with 20 to 80% by weight of hydrophobic, substantially water insoluble monomers, 20 to 80% by weight of water-soluble, salt-forming monomers from the group of ethylenically unsaturated sulfonic acids, and 0 to 50% by weight of ethylenically unsaturated monocarboxylic or dicarboxylic acids or the anhydrides thereof, each in relation to the total weight of the water soluble copolymer.
