Dye mixtures contain 1-hydroxy-2-(vinylsulfonyl-2-hydroxyphenylazo)-7 -(3-hydroxy-2-phenyl-pyrrol-4-yl-azo)-naphthalene-3-sulfonic acid (precursor) copper (Cu) complex dyes (I) and N-(2-hydroxyphenyl)-ms-phenyl-N'-(2-carboxy- or -sulfo-phenyl)-formazan Cu complex dyes (II). Dye mixtures contain 1-hydroxy-2-(vinylsulfonyl-2-hydroxyphenylazo)-7 -(3-hydroxy-2-phenyl-pyrrol-4-yl-azo)-naphthalene-3-sulfonic acid (precursor) copper (Cu) complex dyes of formula (I) and N-(2-hydroxyphenyl)-ms-phenyl-N'-(2-carboxy- or -sulfo-phenyl)-formazan Cu complex dyes of formula (II): [Image] M : hydrogen (H) or an alkali(ne earth) or ammonium ion; R 1>H, 1-4 carbon (C) alkyl or alkoxy, sulfo, bromo or chloro (Cl); R 2>H, 1-6C alkyl or carboxy(alkyl); R 3>H, sulfo or SO 2Y 1>; R 4>, R 6>H or sulfo; R 5>as R 4>, methyl, carboxyl or SO 2Y 2>; R 7>, R 8>H, alkyl, sulfo or Cl; W : C or -SO-; A : SO 2Y 3> or a group of the formula *-N(H)B; Y, Y 1>,Y 2>, Y 3>vinyl or CH 2CH 2Z; Z : a group eliminated by alkali; * : the bond to the formazan; B : a substituted pyrimidyl, s-triazinyl or sullfo-aryl- or -alkyl-carbamoyl group. The full definitions are given in the DEFINITIONS (Full Definitions) Field. An independent claim is also included for the production of the mixture by mechanical mixing of the required proportions of (I) and (II) in solid or liquid form. |
