    Abstract: Polymer (I) derived from the following monomer mixture (wt.%) is new: (A) a monomer whose homopolymer has a glass transition temperature (Tg) below 30 degrees C (45-74.9); (B) a monomer whose Tg is above 50 degrees C (25-54.9); (C) a crosslinking monomer having at least two nonconjugated vinyl groups (0.001-0.1); (D) a monomer containing acid groups (0-4); and (E) other monomer(s) (0-2). Independent claims are also included for the following: (1) a coating composition containing a binder comprising (I) produced by radical-initiated aqueous emulsion polymerization; and (2) an aqueous polymer dispersion comprising (I).

    Abstract: A pigment-comprising formulation for coating substrates, comprising:(i) an aqueous dispersion of at least one water-insoluble polymer P which has phosphonate groups, as a binder, said polymer P having a glass transition temperature Tg in the range of -60° to 80° C.,(ii) at least one inorganic pigment,(iii) optionally, one or more inorganic fillers, and(iv) at least one auxiliary,wherein water-insoluble polymer P is obtained by free-radical aqueous emulsion polymerization of ethylenically unsaturated monomers comprising:90 to 99.9% by weight of at least one monomer a, which is selected from the group consisting of vinylaromatic monomers, the esters of acrylic acid with C1-C12-alkanols, the vinyl esters of aliphatic C1-C12-monocarboxylic acids, ethylene and vinylchloride, and0.1 to 10% by weight of at least one phosphonate group containing monomer.
