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

摘要

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 IMAGE (1) 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, -NH2, or the group of the formula IMAGE EACH OF Ar1 and Ar2 independently represents an aromatic radical, EACH OF R1 and R2 independently represents hydrogen, lower alkyl or hydroxy-lower alkyl, EACH OF X, X1, X2, Y1, Y2, V1 and V2 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 X1 and X2 and Y1 and Y2, together with the nitrogen atom to which it is attached, represents a 5- or 6-membered heterocyclic radical, An(-) represents the anion of an organic or inorganic acid, and N IS 1 OR 2.
