Abstract

Aqueous dispersions comprising as component A) a compound containing two or more blocked isocyanate groups in the molecule and as component B) a compound obtainable by reacting a diepoxy compound with a diamine or polyamine and subsequently reacting the resulting reaction product with an acid and possibly as component C) a dispersant are suited together with fluorine containing oligomers or polymers for the oil-, water- and soil-repellent finishing of fiber materials.
