Claim:
A dye mixture which comprises dyes of the formula (1) and dyes of the formula (2): wherein M is hydrogen or an alkali metal, an ammonium or the equivalent of an alkaline earth metal ion; Y is vinyl or is a moiety of the formula CH 2 CH 2 Z, where Z is an alkali-eliminable moiety; R 1 is hydrogen, C 1 -C 4 alkyl, C 1 -C 4 alkoxy, sulfo, bromo or chloro; R 2 is hydrogen, C 1 -C 6 -alkyl, carboxyl or carboxyalkyl; R 3 is hydrogen, sulfo or SO 2 Y 1 , where Y 1 has one meaning of Y; R 4 is hydrogen or sulfo; R 5 has one meaning of R 4 or is methyl, carboxyl or SO 2 Y 2 , where Y 2 has one meaning of Y; R 6 has one meaning of R 4 ; R 7 is hydrogen, alkyl, sulfo or chloro; R 8 has one meaning of R 7 ; W is a carbon or —SO—; A is a moiety of the formula (3): where * denotes the bond to formazan and B is a moeity of the formulae (4), (5), (6) or (7): where * is the bond to N in the formula (3) U is a 5- or 6-membered N-attached heterocyclic ring which is optionally substituted by a thio, oxo group, or a group of the formula (8): where E is hydrogen, unsubstituted C 1 -C 4 alkyl, methoxy-substituted C 1 -C 4 alkyl, hydroxyl-substituted C 1 -C 4 alkyl, sulfato-substituted C 1 -C 4 alkyl, sulfo-substituted C 1 -C 4 alkyl, chloro-substituted C 1 -C 4 -alkyl or is phenyl which is optionally substituted by one or 2 substituents selected from the group consisting of chlorine, nitro, acetylamino, sulfo, hydroxyl, carboxyl, C 1 -C 4 -alkanoyl, C 1 -C 4 -alkoxy and C 1 -C 4 -alkyl; G has one of the meanings of E or is cyano; L is phenylene or naphthalene which each is optionally substituted by up to two substituents selected from the group consisting of chloro, bromo, hydroxyl, C 1 -C 4 -alkoxy, C 1 -C 4 -alkyl, sulfo and cyano; or L is C 2 -C 6 -alkylene, which is optionally interrupted by 1 to 2 hetero groups; Q is fluorine, chlorine, C 1 -C 4 alkoxy, cyanamido, amino, C 1 -C 4 -alkylamino, dialkylamino, piperazine, morpholine or a group of the formula (9a) or (9b); where A − is fluoride, chloride or the equivalent of a sulfate ion; V has one of the meanings of E; T 1 is hydrogen, fluorine or chlorine; T 2 is hydrogen, fluorine or chlorine, subject to the proviso that T 1 and T 2 are not both hydrogen; X 1 is fluorine or chlorine; and X 2 has one meaning of X 1 .
