1. A process for preparing copper complex dyes of the formula IX, or mixtures thereof: wherein at least one of M1 and M2 is copper (II) and any which is not is hydrogen or methyl, and X is hydrogen, which comprises:(1) preparing an azoxy dye of the formula ?wherein R1 is selected from the group cons
1. A process for preparing copper complex dyes of the formula IX, or mixtures thereof: wherein at least one of M1 and M2 is copper (II) and any which is not is hydrogen or methyl, and X is hydrogen, which comprises:(1) preparing an azoxy dye of the formula ?wherein R1 is selected from the group consisting of methoxy, hydroxyl and carboxyl, by a process which comprises coupling a coupling component of the formula IV ?wherein R2 is selected from the group consisting of carboxyl, amino, C1-C4-alkylamino, allylamino, benzylamino and methoxycarbonylmethylamino, and the phenyl rings A may additionally be substituted by C1-C8-alkyl, unsubstituted or methyl- or halogen-substituted phenyl, hydroxyl, amino, nitro, halogen, carboxyl, N-benzylcarbamoyl, unsubstituted or nitro-, halogen-, C1-C4-alkoxy- or acetoxy-substituted phenylcarbamoyl and naphthylcarbamoyl or be benzofused, ?with nitroaniline of the formula V ?reducing the resultant nitro monoazo dye, and deacylating in aqueous solution at pH<9; and (2) reacting the dye obtained in (1) with at least 0.1 mol equivalent of a copper donor. 2. A process for preparing copper complex dyes as claimed in claim 1, wherein M1 and M2 are copper (II).3. A process for preparing copper complex dyes as claimed in claim 1, wherein R1 is methoxy.4. A process for preparing copper complex dyes as claimed in claim 1, wherein the phenyl rings A are unsubstituted or C1-C4-alkyl-substituted.5. A process for preparing copper complex dyes as claimed in claim 1, wherein each R2 is carboxyl.6. A process for preparing copper complex dyes as claimed in claim 1, wherein the dye obtained in (1) is reacted with 0.1-2 mol copper donor per mol of dye.7. A process for preparing copper complex dyes as claimed in claim 1, wherein the dye obtained in (1) is reacted with 0.5-1.7 mol copper donor per mol of dye.8. A process for preparing copper complex dyes as claimed in claim 1, wherein the copper donors are salts which contain the copper as cation.9. A process for preparing copper complex dyes of the formula IX, or mixtures thereof: wherein at least one of M1 and M2 is copper (II) and any which is not is hydrogen or methyl, and X is hydrogen, which comprises:(1) preparing an azoxy dye of the formula ?wherein R1 is selected from the group consisting of methoxy, hydroxyl and carboxyl, by a process which comprises coupling a coupling component of the formula IV ?wherein n is 1, and R2 is selected from the group consisting of carboxyl, amino, C1-C4-alkylamino, allylamino, benzylamino and methoxycarbonylmethylamino, and the phenyl rings A may additionally be substituted by C1-C8-alkyl, unsubstituted or methyl- or halogen-substituted phenyl, hydroxyl, amino, nitro, halogen, carboxyl, N-benzylcarbamoyl, unsubstituted or nitro-, halogen-, C1-C4-alkoxy- or acetoxy-substituted phenylcarbamoyl and naphthylcarbamoyl or be benzofused, ?with nitroaniline of the formula V ?reducing the resultant nitro monoazo dye, and deacylating in aqueous solution at pH<9; and (2) reacting the dye obtained in (1) with at least 0.1 mol equivalent of a copper donor. 10. A process for preparing azoxy dyes of the formula where R1 is selected from the group consisting of methoxy, hydroxyl and carboxyl, which comprises coupling a coupling component of the formula IV ?with nitroaniline of the formula V ?wherein R2 is selected from the group consisting of carboxyl, amino, C1-C4-alkylamino, allylamino, benzylamino and methoxycarbonylmethylamino, and the phenyl rings A may additionally be substituted by C1-C8-alkyl, unsubstituted or methyl- or halogen-substituted phenyl, hydroxyl, amino, nitro, halogen, carboxyl, N-benzylcarbamoyl, unsubstituted or nitro-, halogen-, C1-C4-alkoxy- or acetoxy-substituted phenylcarbamoyl and naphthylcarbamoyl or be benzofused, ?reducing the resultant nitro monoazo dye, and deacylating in aqueous solution at pH<9.
