摘要：
The present invention relates to binder compositions which are based on polymer dispersions and comprise boric acid or salts of boric acid as crosslinking agents, 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 having a glass transition temperature in the range from −50° C. to 50° C., obtainable by free-radical polymerization of ethylenically unsaturated monomers M, the monomers M comprising: 80% to 99.9% 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 20% by weight, based on the total amount of monomers M, of at least one monoethylenically unsaturated monomer M2 which carries at least one carboxyl group and/or at least one carboxamido group (CONH2); and b) boric acid and/or at least one salt of boric acid.
