Zusammenfassung: | Use of pyridine dyes of the formula or , in which R is optionally substituted C1-C20-alkyl, optionally substituted phenyl or hydroxyl, R is a carbocyclic or heterocyclic radical, R is cyano, carbamoyl, carboxyl or C1-C4-alkoxycarbonyl, R is oxygen or the radical of a CH-acidic compound, R is hydrogen or C1-C4-alkyl, R is optionally substituted C1-C20-alkyl, optionally substituted phenyl, hydroxyl or optionally substituted amino, and X is nitrogen or alternatively may be CH, for dyeing or printing synthetic fibres, cellulose esters or mixtures (blends) thereof, dye mixtures containing pyridine dyes of the above formulae and blue disperse dyes, their use for dyeing or printing synthetic fibres, cellulose esters or mixtures (blends) thereof, and triazolopyridine dyes containing a thienyl radical. |
