Abstract

Triazolopyridine dyes of the formula ##STR1## where R.sup.1 is unsubstituted or substituted C.sub.1 -C.sub.20 -alkyl, unsubstituted or substituted phenyl, unsubstituted or substituted hydroxyl or unsubstituted or substituted mercapto, PA1 Q is a radical of the formula ##STR2## where R.sup.2 is a carbocyclic or heterocyclic radical, PA1 R.sup.3 is hydrogen or unsubstituted or substituted C.sub.1 -C.sub.4 -alkyl, PA1 R.sup.4 is hydrogen, unsubstituted or substituted C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -alkoxy, PA1 R.sup.5 is unsubstituted or substituted C.sub.1 -C.sub.8 -alkyl, unsubstituted or substituted phenyl, unsubstituted or substituted thienyl or unsubstituted or substituted C.sub.1 -C.sub.4 -alkoxy, or the radical CR.sup.3 R.sup.4 R.sup.5 together is C.sub.3 -C.sub.7 -cycloalkyl, C.sub.1 -C.sub.4 -haloalkyl, unsubstituted or substituted phenyl or unsubstituted or substituted thienyl, PA1 R.sup.6 is cyano, carbamoyl, carboxyl, C.sub.1 -C.sub.4 -alkoxycarbonyl or benzothiazolyl, and PA1 E is CH or nitrogen, and PA1 R.sup.7 is oxygen or a radical of an acidic--CH compound, a process for the thermal transfer of these dyes, their use for dyeing or printing synthetic materi…
