Abstract
Products which are produced by reaction of diisocyanates with di- or polyhydric alcohols and/or with one or more mono- and/or diethers of such alcohols and subsequent reaction with organic amines containing two or more alcoholic hydroxyl groups and subsequent blocking of free isocyanate groups are suitable for the finishing of fiber materials, in particular in the form of aqueous dispersions as extenders for use in combination with polymers containing perfluoroalkyl groups for the oil-, water- and soil-repellent finishing of fiber materials.
