Process for dyeing or printing cellulosic textile fibre material by the trichromatic technique: reactive dyes

A process for dyeing or printing cellulosic textile fibre materials by the trichromatic technique, which process comprises dyeing or printing said materials from an aqueous liquor with at least one red or reddish brown dyeing dye of formula ##STR78## and at least one yellow or orange dyeing dye of formula ##STR79## and at least one blue dyeing dye of formula ##STR80## in which formulae (1), (2) and (3) above the benzene rings A.sub.1, A.sub.2 and B.sub.1 may be further substituted, and the benzene rings A.sub.1, A.sub.2 and B.sub.1, together with the fused benzene rings indicated in dashed outline, denote possible alternative naphthalene rings, (B.sub.2).sub.1-3 denotes 1 to 3 substituents B.sub.2, each independently of one another selected from the group consisting of hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.2 -C.sub.4 alkanoylamino, halogen, nitro, cyano, trifluoromethyl, sulfamoyl, carbamoyl, amino, hydroxy, carboxy, sulfomethyl, sulfo or ureido, R.sub.1 and R.sub.3, each independently of the other, are hydrogen, C.sub.1 -C.sub.4 alkyl or phenyl, and R.sub.2 is hydrogen, cyano, carbamoyl or sulfomethyl, (R.sub.4).sub.1-2 denotes 1 to 2 substituents R.sub.4, each independently of the other selected from the group consisting of hydrogen and sulfo, (X).sub.1-2 denotes 1 to 2 substituents X, each independently of the other selected from the group consisting of hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, halogen, C.sub.2 -C.sub.4 alkanoylamino, hydroxy, carboxy, sulfo, cyano or nitro, q is 0 or 1, (T.sub.1).sub.1-2 denotes 1 to 2 substituents T.sub.1, each independently of the other selected from the group consisting of sulfo and --SO.sub.2 --Z', where Z' is .beta.-sulfatoethyl, .beta.-haloethyl or vinyl, (T.sub.2).sub.1-2 denotes 1 to 2 substituents T.sub.2, each independently of the other selected from the group consisting of hydrogen and sulfo, T.sub.3 is the radical --NH--Z or --CONH--(CH.sub.2).sub.2-3 --SO.sub.2 --Z', and Z' has the given meaning, (Y).sub.1-3 denotes 1 to 3 substituents Y, each independently of one another selected from the group consisting of hydrogen and C.sub.1 -C.sub.4 alkyl, and Z in formulae (1) to (7) is a 2-chloro-s-triazin-6-yl radical which contains in 4-position an unsubstituted or substituted amino group.
