| 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). |
