Reactive disazo dyes having two cyanuric chloride mechanisms

A disazo dye of the formula I ##STR353## where n is 0, 1 or 2,

• D is unsubstituted or substituted phenyl or unsubstituted or substituted naphthyl,
• R.sup.1 and R.sup.2 independently of one another, are each hydrogen or unsubstituted or substituted C.sub.1 -C.sub.4 -alkyl,
• R.sup.3 is hydrogen,
• Z is a radical of the formula NR.sup.4 R.sup.5, where R.sup.4
• is hydrogen or unsubstituted or substituted C.sub.1 -C.sub.4 -alkyl and R.sup.5 is hydrogen, unsubstituted or substituted C.sub.1 -C.sub.4 -alkyl or unsubstituted or substituted phenyl, and
• Q is a radical of the formula ##STR354## with the proviso that a) from five to seven groups which impart water solubility are present in the molecule wherein the substituents on the substituted phenyl or substituted naphthyl are selected from the group consisting of C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, amino, halogen, hydroxysulfonyl, carboxyl, sulfamoyl, C.sub.1 -C.sub.4 -mono- or dialkylsulfamoyl, whose alkyl radicals are unsubstituted or substituted by hydroxyl, and C.sub.1 -C.sub.4 -alkylsulfonyl, which is unsubstituted or substituted by hydroxyl;
• and wherein the substituents on said substituted C.sub.1 -C.sub.4 -alkyl are selected from the group consisting of hydroxyl, C.sub.1 -C.sub.4 -alkoxy, hydroxy-C.sub.1 -C.sub.4 -alkoxy, sulfato, halogen, C.sub.1 -C.sub.4 -alkoxycarbonyl, cyano, carboxyl and hydroxysulfonyl;
• and wherein the groups which impart water solubility are selected from the group consisting of carboxyl and hydroxysulfonyl.
