Abstract
The present invention provides dye mixtures containing a dye of the formula (I) and a dye of the formulae (II) where Z is —CH═CH2 or —CH2CH2Z1 and Z1 is hydroxyl or an alkali-eliminable group; and M is hydrogen, an alkali metal or one equivalent of an alkaline earth metal. The invention also relates to a process for their preparation and their use.
Claims17
Dye mixture comprising a dye of the formula (I)
- and a dye of the formulae (II)
- where
- Z is —CH═CH2 or —CH2CH2Z1 and
- Z1 is hydroxyl or an alkali-eliminable group;
- and
- M is hydrogen, an alkali metal or an alkaline earth metal.
The dye mixture as claimed in claim 15, wherein Z1 is hydroxyl, halogen atoms, ester groups of organic carboxylic and sulfonic acids, benzoyloxy, sulfobenzoyloxy, phenylsulfonyloxy and toluoylsulfonyloxy, acidic ester groups of inorganic acids, or dialkylamino groups having alkyl groups of 1 to 4 carbon atoms each.
The dye mixture as claimed in claim 15, wherein Z1 is hydroxyl, chlorine and bromine, alkylcarboxylic acids, substituted or unsubstituted benzenecarboxylic acids, substituted or unsubstituted benzenesulfonic acids, acetyloxy, benzoyloxy, sulfobenzoyloxy, phenylsulfonyloxy toluoylsulfonyloxy, phosphoric acid, sulfuric acid thiosulfuric acid dimethylamino or diethylamino.
The dye mixture as claimed in claim 15, wherein Z1 is vinyl, β-chloroethyl or β-sulfatoethyl
