AQUEOUS BINDER COMPOSITIONS

The present invention relates to aqueous binder compositions which are based on aqueous polymer dispersions, to processes for preparing them, and to their uses. The aqueous binder composition comprises: a) a water-insoluble polymer P in the form of dispersed polymer particles, i.e., in the form of a...

Beschreibung
Zusammenfassung:	The present invention relates to aqueous binder compositions which are based on aqueous polymer dispersions, to processes for preparing them, and to their uses. The aqueous binder composition comprises: a) a water-insoluble polymer P in the form of dispersed polymer particles, i.e., in the form of an aqueous polymer dispersion, the polymer P being obtainable by polymerization of ethylenically unsaturated monomers M, the monomers M comprising: 90% to 99.9% by weight, more particularly 92% to 99.5% by weight and especially 93% to 99% by weight, based on the total amount of monomers M, of at least one neutral, monoethylenically unsaturated monomer M1 of low water-solubility; and 0.1% to 10% by weight, more particularly 0.5% to 7% by weight and especially 1% to 5% by weight, based on the total amount of monomers M, of at least one monoethylenically unsaturated monomer M2 which is selected from monoethylenically unsaturated monomers which have at least two hydroxyl groups attached to vicinal C atoms, and monomers which carry a functional group which can be converted by hydrolysis into two hydroxyl groups attached to vicinal C atoms; and b) boric acid and/or at least one salt of boric acid.
