    Abstract: Acetalized azo dyes are prepared by diazotizing an amine, coupling with a hydroxyalkyl-containing coupling component and subsequently reacting with a vinyl ether in a process which comprises carrying out the coupling reaction in a two-phase reaction mixture comprising water and an aromatic hydrocarbon, subsequently separating off the aqueous phase and reacting the azo dye, which is present in the organic phase, without intermediate isolation, with a vinyl ether in the presence of a polybasic carboxylic acid as catalyst.

    Abstract: Dyestuff mixtures comprising at least one azo dyestuff whose diazo component is 2-amino-3,5-dicyano-4-methylthiophene and whose coupling component originates from the 2-amino-4-thienylthiazole series, and at least one azo dyestuff whose diazo component is 2-amino-3,5-dicyano-4-methylthiophene, 2-amino-3-alkoxycarbonyl-5-cyano-4-methylthiophene or 2-amino-5-alkoxycarbonyl-3-cyano-4-methylthiophene and whose coupling component originates from the 3-cyano-4-methyl-2,6-diaminopyridine series, and/or at least one azo dyestuff whose diazo component is a 2,6-dicyano-4-alkylaniline and whose coupling component originates from the m-phenylenediamine series, and the use of the novel dyestuff mixtures for the dyeing or printing of synthetic fabrics.
