Abstract:
A water soluble or water-dispersible polymeric salt of:A) at least one polymer PA) having free acid groups and a neutralizing agent which comprises at least one compound VA) having at least two free amino groups per molecule, or B) at least one polymer PB) having free amino groups and a neutralizing agent which comprises at least one di- or polyvalent inorganic acid and/or at least one compound VB) having at least two free acid groups per molecule, where compounds VA) and VB) additionally have at least one hydrophilic group, which is chosen from other ionogenic and/or ionic groups, divalent radicals of polyethers, divalent radicals of pyrrolidone-containing polymers and combinations thereof, where the component PA) or PB) comprises at least one pyrrolidone-containing polymer obtained by reacting monomeric mixture which comprisesh) itaconic acid and/or a derivative thereof, and i) at least one diamine of the formula I H2Nâ€”Aâ€”NHR1â€ƒâ€ƒ(I) â€ƒin which R1 is hydrogen or C1-C4-alkyl, A is a C2-C20-alkylene radical, which can be interrupted by at least one or more nonadjacent, identical or different â€”NR2- groups, where R2 is hydrogen, C1-C4-alkyl, C5-C8-cycloalkyl, phenyl or phenyl-C1-C4-alkyl.
