Paints and renders contain, as binders, aqueous dispersions of copolymers which have a minimum film-forming temperature of from -15 DEG to 20 DEG C. and consist of (a) from 10 to 50% by weight of vinylidene chloride, up to half of which may be replaced with vinyl chloride, (b) from 44 to 88% by weight of esters of acrylic and/or methacrylic acid with alkanols of 1 to 18 carbon atoms and, if required, styrene, vinyl acetate, vinyl propionate or a mixture of these monomers and (c) from 2 to 6% by weight of alpha , beta -monoolefinically unsaturated mono- and/or dicarboxylic acids of 3 to 5 carbon atoms and/or their amides. |
