Abstract: The present invention relates to the use of compositions comprising at least one aqueous polymer dispersion wherein the polymer has carbonyl or oxirane groups (component a)) and at least one compound with at least two NH2 groups per molecule as sealing or coating compositions, especially for substrates with a hydrophobic surface. The present invention further relates to coating compositions containing such binder formulations.

Abstract: A process for preparing aqueous polymer dispersions comprises first of all subjecting ethylenically unsaturated monomers to free-radical aqueous emulsion polymerization to prepare an aqueous dispersion of a polymer 1 having a glass transition temperature Tg1, then dissolving further, comparatively hard monomers in the dispersed particles of the polymer 1, and subsequently carrying out free-radical polymerization of the monomers dissolved in the particles.
