    Abstract: The present invention relates to polymer dispersion-based binder compositions comprising boric acid or salts of boric acid as cross-linking agents, to a method for the production thereof and to use thereof. The aqueous binder composition comprises: a) a water-insoluble polymer (P) in the form of dispersed polymer particles with a glass transition temperature in the range of -50°C to 50°C, obtained through radical polymerization of ethylenically unsaturated monomers M, wherein the monomers M contain: 80 to 99.9 wt %, relative to the total amount of monomers M, of at least one slightly soluble neutral monoethylenically unsaturated monomer M1; and 0.1 to 20 wt %, relative to the total amount of monomers M, of at least one monoethylenically unsaturated monomer M2 that contains at least one carboxyl group and/or at least one carboxylic acid amide group (CON-H2); and b) boric acid and/or at least one salt of boric acid.
