This invention relates to a binder suitable for use in fixing a pigment on a material which is in fibre or sheet-like form, comprising a dispersion or emulsion of a polymer which can be cured to give a water-insoluble coating, this dispersion or emulsion containing 0.5 to 30% by weight, calculated on the polymer solids content, of a salt of a sulphated oleic acid amide of the formula I R1R2N-CO-C17H34-OSO3X (I) wherein R1 denotes hydrogen or alkyl with 1-6 C atoms, R2 denotes hydrogen, alkyl with 1-6 C atoms or phenyl, and X denotes a monovalent cationic atom or radical, and to its use. Application of said binder prevents or at least considerably delays the formation of undesired coatings, covering parts of the dyeing and printing equipment and results in more uniform surface appearance of the dyed and printed material and in a reduction of dyestuff migration.
