Dye mixtures of fiber-reactive azo dyes, their preparation and use

1. Reactive dye mixtures comprising one or more dyes, of the general formula (I),

in an amount of 30 to 95% by weight,

one or more, dyes of the general formula (II),

in an amount of 1 to 65% by weight,

and one or more dyes of the general formula (Ga)

in an amount of 1 to 65% by weight,

where:

D 1 , D 2 , D 3 , D 4 and D 6 are independently each a group of the general formula (1)

where

R 1 and R 2 are each hydrogen,

X 1 is hydrogen or a group of the formula —SO 2 —Z,

where

Z is —CH═CH 2 , or β-sulfatoethyl;

R* is hydrogen;

R** is

a group of the formula (14)

—CH 2 —SO 3 M  (14);

R 31 hydrogen and

M is hydrogen, an alkali metal or an equivalent of an alkaline earth metal.

2. Reactive dye mixtures as claimed in claim 1 , comprising one or more monoazo dyes of the general formulae (17) to (18), each in an amount of 0-10% by weight

where M, R*, R** and D 3 are as defined in claim 1 .

3. The reactive dye mixture as claimed in claim 1 , further comprising

one or more monoazo dyes of the formula (15),

one or more monoazo dyes of the formula (16),

or a mixture of one or more monoazo dyes of the formula (15) and one or more monoazo dyes of the formula (16)

where D 2 and M are as defined in claim 1 .

4. An aqueous liquid preparation comprising a dye mixture as claimed in claim 1 with a total dye content of 5-50% by weight.

5. A process for dyeing which comprises contacting the reactive dye mixtures as claimed in claim 1 with a hydroxyl- and/or carboxamido-containing fiber material.

6. A process for producing the reactive dye mixture as claimed in claim 1 , which comprises mixing the individual dyes of the formulae (I), (II) and (Ga) with one another mechanically in solid form or in the form of an aqueous solution.
