Abstract
A process for improving the color yield and the wetfastness properties of dyeings produced on cellulose fibre material with anionic dyes, which process comprises treating the cellulose material before, during or after dyeing, with a cationic fibre-reactive compound of the formula ##STR1## wherein B represents a mono- or polynuclear heterocyclic radical, PA1 Hal represents a reactive halogen atom, PA1 X represents halogen, lower alkoxy, lower alkylthio, phenoxy, phenylthio, ##STR2## or the group of the formula ##STR3## each of W.sub.1 and W.sub.2 independently represents the direct bond, ##STR4## Z represents hydrogen, lower alkyl or hydroxy-lower alkyl, each of Q.sub.1 and Q.sub.2 independently represents an aliphatic or cycloaliphatic radical, each of PA1 R.sub.1, R.sub.2, V.sub.1, V.sub.2, Y.sub.1 and Y.sub.2 independently represents lower alkyl, or lower alkyl or benzyl each of which is substituted by halogen, hydroxy or cyano, or each of the pair of substituents R.sub.1 and R.sub.2 and Y.sub.1 and Y.sub.2 together with the nitrogen atom to which it is attached independently represents a 5- or 6-membered heterocyclic ring, or each of PA1 R.sub.1, R.sub.2 and V.sub.1 and Y.sub.1,…
