Abstract

An aqueous composition containing (A) an aminoplast precondensate, (B) a polymeric ethylene imine, the monomer of which is a reaction product of toluenediisocyanate a fluorinated alkanol and ethylene imine, which polymer is dispersed by means of a dispersant obtained by reacting said fluorinated alkanol, toluenediisocyanate and a polyethylene glycol, (C) a long-chain alkyl urea and (D) a cross-linking catalyst is useful for rendering a velvety suede-like polyurethane structure oil- and water-repellant.
