Aqueous secondary dispersions containing phosphate groups are obtainable by copolymerization of (A) 25-98% by weight of acrylates and/or methacrylates, (B) 1-10% by weight of acrylic and/or methacrylic acid, (C) 1-8% by weight of a compound of the general formula <IMAGE> where R1 and R2 are each hydrogen and/or a C1-C8-hydrocarbon radical and Z is a straight-chain or branched C1-C8-alkylene, and (D) 0-60% by weight of a copolymerizable olefinically unsaturated compound, in an organic solvent, neutralization of the copolymer solution and dilution with water and, if required, removal of solvent by distillation.
