The invention relates to a dye mixture containing a dye of the formula <IMAGE> (1) in which R1 is methyl or ethyl and at least one dye of the formulae (2) to (4) <IMAGE> (2) in which R2 is halogen, benzoylamino which is unsubstituted or substituted in the phenyl ring by halogen, 1-azacycloheptane-N-sulfonyl or <IMAGE> in which R5 is C1-C8alkyl or phenyl which is unsubstituted or substituted by C1-C4alkyl, and R6 is hydrogen, or R5 and R6 are C1-C8alkyl, R3 is hydrogen, halogen or C1-C8alkyl, and R4 is hydrogen or halogen, <IMAGE> (3) in which D is substituted or unsubstituted phenyl, thiophenyl or benzothiazolyl, R7 is C1-C8alkyl, R8 is substituted or unsubstituted C1-C8alkyl, and R9 is hydrogen or C1-C4alkyl, and <IMAGE> (4) in which R10 is C1-C4alkyl. The dye mixture is extinguished by generally good properties, in particular by good exhaustion.
