O.Z. 0050/033,017 Abstract of the Disclosure: Aqueous dispersions of carbonyl-containing copolymers, which dispersions contain from 0.02 to 1 mole, per mole of carbonyl group, of organic hydrazine derivatives possessing 2 or more hydrazine radi-cals, and from 0.0002 to 0.02 mole, per mole of the hydrazine derivatives, of heavy metal ions give coatings, impreg-nations and finishes which are particularly easy to cross-link. |
