ABSTRACT:
Dyes suitable for dyeing and printing cellulose-containing fiber materials which produce blue dyeings and prints having good fastness properties. These dyes are of the formula ##STR1## wherein R.sub.1 and R.sub.2 are each independently of the other hydrogen, halogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, phenoxy, carboxyl carbamoyl or C.sub.1 -C.sub.4 alkanoylamino; R.sub.3 is hydrogen, sulfo, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, halogen, carboxyl, carbamoyl, N-C.sub.1 -C.sub.4 alkylcarbamoyl, N,N-di-C.sub.1 -C.sub.4 alkylcarbamoyl, C.sub.1 -C.sub.4 alkylsulfonyl, sulfamoyl, N-C.sub.1 -C.sub.4 alkylsulfamoyl or N,N-di-C.sub.1 -C.sub.4 alkylsulfamoyl; R.sub.4 is a radical of the formula ##STR2## R.sub.5 and R.sub.6 are independently of each other hydrogen or unsubstituted or hydroxyl-, sulfo-, sulfato-, carboxyl-, cyano-, halogen-, C.sub.1 -C.sub.4 alkoxycarbonyl-, C.sub.1 -C.sub.4 alkanoyloxy- or carbamoyl-substituted and uninterrupted or, except in the case of methyl, --O--, --S-- or --NH--interrupted C.sub.1 -C.sub.6 alkyl; R' is hydrogen or C.sub.1 -C.sub.6 alkyl; t is an integer from 0 to 4; the phenyl radical (a) is unsubstituted or substituted by C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkyl substituted by hydroxyl-, sulfo or sulfato, C.sub.1 -C.sub.4 alkoxy, halogen, sulfo, carboxyl or hydroxy, and A is a radical of the formula ##STR3## where R' is as defined above, (alk) is C.sub.1 -C.sub.6 alkylene, T is hydrogen, halogen, hydroxyl, sulfato, carboxyl, cyano, C.sub.1 -C.sub.4 alkanoyloxy, C.sub.1 -C.sub.4 alkoxycarbonyl, carbamoyl or a radical --SO.sub.2 --Z, V is hydrogen, substituted or unsubstituted C.sub.1 -C.sub.4 alkyl or a radical of the formula -(alk)--CH.sub.2 --SO.sub.2 --Z, where (alk) is as defined above, Z is a radical of the formula --CH.dbd.CH.sub.2 l or --CH.sub.2 --CH.sub.2 --Y, Y is a leaving group selected from the group consisting of --OSO.sub.3 H, --SSO.sub.3 H, --OCOCH.sub.3, --OCO--C.sub.6 H.sub.5, OPO.sub.3 H.sub.2, --Cl, Br, --F, ##STR4## p, q and r are each independently of the others an integer from 1 to 6.
