Process for improving the color yield and fastness properties of dyeings produced with anionic dyes on cellulose fibre material and fluorine-containing cationic compounds

Abstract

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, W represents a reactive fluorine atom, Z represents halogen, lower alkyl, phenyl, lower alkoxy, lower alkylthio, phenoxy, phenylthio, --NH 2 , or the group of the formula ##STR2## EACH OF Ar 1 and Ar 2 independently represents an aromatic radical, Each of R 1 and R 2 independently represents hydrogen, lower alkyl or hydroxy-lower alkyl, Each of X, x 1 , x 2 , y 1 , y 2 , v 1 and V 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 X 1 and X 2 and Y 1 and Y 2 , together with the nitrogen atom to which it is attached, represents a 5- or 6-membered heterocyclic radical, An.sup.⊖ represents the anion of an organic or inorganic acid, and N is 1 or 2.
