    摘要： The present invention provides for the use of an aqueous dispersion of particles composed of polymer and finely divided inorganic solid (aqueous composite-particle dispersion) as a binder in elastic coatings, such as paints, more particularly exterior architectural paints, comprising preparing the aqueous composite-particle dispersion by dispersely distributing ethylenically unsaturated monomers in an aqueous medium and carrying out polymerization by means of at least one free-radical polymerization initiator in the presence of at least one dispersely distributed, finely divided inorganic solid having an average particle diameter ≦100 nm and at least one dispersant by the method of free-radically aqueous emulsion polymerization, and using as ethylenically unsaturated monomers a monomer mixture which comprises ethylenically unsaturated monomers A and optionally 0% to ≦10% by weight of an ethylenically unsaturated monomer B containing an epoxide group (epoxide monomer).

    摘要： Coating compositions containing an aqueous polymer dispersion having improved resistance toward chemicals. The aqueous polymer dispersion is prepared by polymerizing a first composition containing at least one ethylenically unsaturated group (monomers) by radical aqueous emulsion polymerization and then, in the presence of a product mixture from the previous polymerization, polymerizing a second composition containing at least one ethylenically unsaturated group (monomers) by radical aqueous emulsion polymerization. The coating compositions are such that the difference between a glass transition temperature of a polymer prepared from the first polymerization and a glass transition temperature of a polymer prepared from the second polymerization is at least 50° C.
