    Abstract: The present invention relates to aqueous binder dispersions for the preparation of, inter alia, paints and finishes, substantially containing (A) from 0.5 to 50% by weight of a phenolic resin precondensate, (B) from 20 to 70% by weight of a copolymer of predominant proportions of alkyl acrylates and/or methacrylates, minor proportions of comonomers with groups capable of crosslinking and other comonomers, the copolymer being in the form of a dispersion and being crosslinkable by a condensation reaction, and (C) from 10 to 70% by weight of a graft elastomer comprising a diene polymer as the base polymer and a copolymer of, substantially, styrene, acrylonitrile and C1-C6-alkyl acrylates and/or methacrylates, as the graft polymer, the graft elastomer being in the form of a dispersion, the percentages being based on the solids content of the total amount of (A), (B) and (C).

    Abstract: Binders for aqueous primers for wood paints contain (A) from 50 to 95% by weight, based on the weight of the primer, of an aqueous dispersion of a vinyl polymer having a particle size of from 0.03 to 0.5 mu m and a minimum film-forming temperature of from 0 DEG to 50 DEG C., the said dispersion being stable to polyvalent ions, and (B) from 5 to 50% by weight, based on the weight of the primer, of a water-soluble polymeric zinc amine complex of a copolymer which has a K value of from 8 to 40 and consists of (a) from 20 to 60% by weight, based on the weight of the copolymer, of an alpha , beta -monoethylenically unsaturated mono- and/or dicarboxylic acid of 3 to 5 carbon atoms and (b) from 40 to 80% by weight, based on the weight of the copolymer, of styrene and/or one or more alkyl (meth)acrylates, where alkyl is of 1 to 8 carbon atoms, the copolymer being reacted with from 2 to 6 moles, based on the carboxyl groups of the copolymer, of ammonia and from 0.8 to 1.2 equivalents of a zinc compound per carboxyl group of the copolymer.
