Abstract

Dye mixtures useful for dyeing or printing synthetic fabrics contain at least one azo dye whose diazo component is 2-amino-3,5-dicyano-4-methylthiophene and whose coupling component comes from the 2-amino-4-thienylthiazole series and also at least one azo dye 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 comes from the 3-cyano-4-methyl-2,6-diaminopyridine series, and/or at least one azo dye whose diazo component is a 2,6-dicyano-4-alkylaniline and whose coupling component comes from the m-phenylenediamine series.
