A dye of the general formula (1)

• where
• M is hydrogen, an alkali metal, the equivalent of an alkaline earth metal or ammonium;
• X is halogen, C1-C4 alkoxy, amino, C1-C4-alkylamino, N,N-(C1-C4)-dialkylamino, anilino or sulfo- or hydroxyl-mono- or -disubstituted anilino or is a group of the formula (a), (b) (c) or (d)
• where A− is fluoride, chloride or the equivalent of a sulfate ion and n is 1 or 2;
• R1 and R2 are independently C1-C6 alkyl, C1-C6-alkoxy, chlorine, C1-C4-alkylcarbonylamino or arylcarbonylamino, or combine to form a grouping of the formula (f) or (g)
• R3 is hydrogen or C1-C6-alkyl;
• Q is a grouping of the formula (e)
• where
• R4 has one of the meanings of R3 or is phenyl or chlorine- or sulfo-substituted phenyl,
• W is C2-C6-alkylene which may be interrupted by 1 or 2 oxygen atoms or —NR5, where R5 has one of the meanings of R3 or is phenyl, and
• Y is vinyl or a grouping of the formula CH2CH2Z, where Z is an alkali-eliminable grouping, or when X is fluorine or chlorine is a group of the formula (a), (b), (c) or (d).
