Abstract
A process for improving the color yield and the wet-fastness properties of dyeings produced on cellulose fibrous material with anionic dyes which process comprises treating the cellulose material before, during or after dyeing, with a fluorine-containing cationic compound of the formula ##STR1## WHEREIN B represents a triazine or pyrimidine radical, PA1 W represents a reactive fluorine atom, PA1 Z represents halogen, lower alkyl, phenyl, lower alkoxy, lower alkylthio, phenoxy, phenylthio, --NH.sub.2, or the group of the formula ##STR2## EACH OF Ar.sub.1 and Ar.sub.2 independently represents an aromatic radical, Each of PA1 R.sub.1 and R.sub.2 independently represents hydrogen, lower alkyl or hydroxy-lower alkyl, Each of PA1 X, x.sub.1, x.sub.2, y.sub.1, y.sub.2, v.sub.1 and V.sub.2 independently represents lower alkyl, benzyl, or lower alkyl which is substituted by halogen, hydroxyl or cyano, and X also represents phenyl or methylphenyl, or Each of the pair of substituents PA1 X.sub.1 and X.sub.2 and Y.sub.1 and Y.sub.2, together with the nitrogen atom to which it is attached, represents a 5- or 6-membered heterocyclic radical, PA1 An.sup..crclbar. represents the anion of an organi…
