A process for dyeing cellulose fibres or cellulose-containing blend fibres with vat dyes, sulfur dyes, leuco vat ester dyes or azoic dyes by the pad dyeing process without incurring ending, in which an aqueous dyeing liquor is used which, aside from the dye, contains a colorless compound of the formula <IMAGE> (1) or of the formula [R1-NH-A-R2]-Zm (2) where Q is <IMAGE> or =N-, Y is hydrogen, halogen, cyano, C1-C5alkyl or C1-C5alkylsulfonyl, V and W, independently of each other, are each R2-X2-, R3-X3-, hydroxyl C1-C5alkoxy or an unsubstituted or C1-C5alkyl- or C5-C6cycloalkyl-monosubstituted or -disubstituted amino group, the alkyl radical being unsubstituted or substituted by hydroxyl, cyano, sulfo or sulfato, R1, R2 and R3, independently of one another, are each an aromatic or heteroaromatic radical, X1, X2 and X3, independently of one another, are each -O-, -S-, <IMAGE> -NH-CO-Phen-NH- or NH-CO-Phen-CO-NH-, R4 ishydrogen, C1-C5alkyl, C5-C6cycloalkyl or phenyl, Phen is an unsubstituted or substituted phenylene group, A is a direct bond, -CO- or -CONH-, Z is an acidic, water-solubilizing group and m is 1 to 6. |
