A fiber-reactive dye mixture contains at least one diamino-disulfonyl-triphendioxazine dye and at least one bis-((hydroxypyrazolyl-azo)-sulfophenyl) type disazo dye. A dye mixture contains at least one triphendioxazine dye of formula (I) and at least one disazo dye of formula (II), prefer at a weight ratio or 98:2 to 10:90. R1, R2 = H or Cl;; Z1 = OM, vinyl or -CH2CH2Q; Q = substituent eliminable with alkali; Z2 = OM, hydroxyethyl, vinyl or -CH2CH2Q; Z3 = vinyl or -CH2CH2Q; Z4 = hydroxyethyl, vinyl or -CH2CH2Q; Y = linear or branched 2-6C alkylene (optionally interrupted by 1 or 2 of NH, O and SO2); X = W or -N(R')CO-V-COOM; or if Z1 and Z2 = OM then X = halo-triazinylamino group of formula (a); X' = Cl or Br; r = 1 or 2; Ra = H, 1-4C alkyl, hydroxyethyl or sulfoethyl; Rb = H, OMe, OEt, Me or Et; W = sulfato, SO3H or COOH; R' = H or 1-4C alkyl; V = direct bond or 1-8C alkylene; R3, R4 = H, 1-4C alkyl, 1-4C alkoxy, SO3H or COOH; B' = direct bond or 1-3C alkylene; M = H, alkali metal or 1 equivalent of alkaline earth metal. An Independent claim is included for the preparation of the dye mixture, by mixing (I) and (II).
