    Abstract: Azo dyes of the formula in which R and R are each hydrogen, C1-C4-alkyl or C1-C4-alkoxy, R is hydrogen or C1-C8-alkyl which is optionally substituted by hydroxyl and can be interrupted by 1 to 3 oxygen atoms, R is C1-C8-alkyl which is optionally substituted by hydroxyl and can be interrupted by 1 to 3 oxygen atoms, and X is cyano or optionally substituted C1-C8-alkoxycarbonyl, with the proviso that at least one hydroxyalkyl radical is present in the molecule, mineral oils containing one or more of the novel dyes, and the use of the novel dyes for labelling mineral oils.

    Abstract: Dye mixtures containing at least 6 identically coloured dyes of the formula in which D is the radical of a diazo component from the aniline, aminothiophene, aminothiazole, aminoisothiazole or aminobenzisothiazole series, and one of the radicals X and X is amino and the other is a radical of the formula in which L is optionally substituted C2-C8-alkylene, R is hydrogen or optionally substituted C1-C4-alkyl, and R is hydrogen, C1-C4-alkyl, benzyl, phenyl or C1-C8-alkanoyl, their use for the dyeing or printing of textile materials, dye mixtures containing thienylazopyridine dyes and anthraquinone dyes, and their use for the dyeing or printing of textile materials.
