Abstract
There are described the use of pyridine dyes of the formula ##STR1## where R.sup.1 is substituted or unsubstituted C.sub.1 -C.sub.20 -alkyl, substituted or unsubstituted phenyl or hydroxyl, PA0 R.sup.2 is a carbocyclic or heterocyclic radical, PA0 R.sup.3 is cyano, carbamoyl, carboxyl or C.sub.1 -C.sub.4 -alkoxy carbonyl, PA0 R.sup.4 is oxygen or the radical of an acidic CH compound, PA0 R.sup.5 is hydrogen or C.sub.1 -C.sub.4 -alkyl, PA0 R.sup.6 is substituted or unsubstituted C.sub.1 -C.sub.20 -alkyl, substituted or unsubstituted phenyl, hydroxyl or substituted or unsubstituted amino, and PA0 X is nitrogen or optionally CH, for dyeing or printing synthetic fibers, cellulose esters or blends thereof, dye mixtures comprising pyridine dyes of the above formulae and blue disperse dyes, the use thereof for dyeing and printing synthetic fibers, cellulose esters or blends thereof, and triazolopyridine dyes having a thienyl radical.
