AbstractCompositions comprising an ester with perfluoroalkyl groups and an oligo- or polyurethane which may likewise contain perfluoroalkyl groups are useful for the oil and water repellant finishing of sheetlike textile materials. The compositions may additionally include acrylic polymers having perfluoroalkyl groups and extenders. Especially the use of nonionic aqueous dispersions of the compositions makes it possible to obtain textiles with little if any effect losses after mechanical abrasion and good LAD effects.
