Abstract: Powder paint composition, processes for preparing and uses for the same. The composition includes (a) at least one polymer powder redispersible in water, (b) pigment and filler and (c) optionally further additives. Where (a) is a polymer stabilized with polyvinyl alcohol, based on (a1) 20 to 100% by weight of at least one monomer from the group consisting of acrylic esters of branched or unbranched alcohols having 1 to 12 carbon atoms, (a2) 0 to 60% by weight of at least one monomer from the group consisting of methacrylic esters of branched or unbranched alcohols having 1 to 12 carbon atoms and styrene, (a3) 0 to 40% by weight of at least one monomer from the group consisting of vinyl esters of branched or unbranched carboxylic acids having 2 to 12 carbon atoms, and (a4) 0 to 20% by weight of other ethylenically unsaturated comonomers copolymerizable therewith.
