    Abstract: Reactive azo dyes of formula (I) are new: (I): in which n =1 or 2; R = H or OH; and D when n = 1, is a residue of formula (II) or when n = 2, is a residue of formula (III); (III): in which the ring A may be benzoannelated; R , R and R independently = H, 1-4 C alkyl, 1-4 C alkoxy, halogen or hydroxysulphonyl; E = H, an heterocyclic anchoring gp. or an aliphatic anchoring gp.; Y = vinyl or C2H4-Q; Q = a gp. that is split off under alkaline reaction conditions; and T = a bridging member, provided that when n = 1, R = OH and R , R and R each = H, E is neither H nor a residue of formula SO2-Y, W -SO2-Y or CONX-W -SO2-Y, in which Y is as above, W = 1-4 C alkylene and X = H or 1-4 C alkyl.

    Abstract: Dye mixtures containing reactive disazo dye(s), which are 8-amino-7-(2-vinylsulphonylphenylazo)-2-(4-vinylsulphonylphenylazo)-1- hydroxynaphthalene-3,5(6)-disulphonic acids or precursors of formula (I), and yellow, orange, red or blue reactive dye(s) are claimed; in which Y , Y = vinyl or CH2CH2Q; Q = a group released under alkaline conditions. Also claimed is a method of preparing mixtures of (I) and blue reactive disazo dye(s) (II), which are different 8-amino-2,7-di-(vinylsulphonylphenylazo)-1-hydroxynaphthalene-3,5(6)-d isulphonic acids or precursors, by using mixtures of the corresponding disazo components in the coupling stage. Pref. (I) can be prepared by diazotising a mixture of 2- and 4-(2-sulphatoethylsulphonyl)aniline and acid coupling with 1-amino-8-hydroxynaphthalene-3,6-disulphonic acid in the ortho-position to the amino group. In a second coupling with 4-(2-sulphatoethylsulphonyl)aniline, a mixture of (I) and Reactive Black 5 (IIA) is obtained. The mixtures can also be prepared by mixing the individual dyes.
