Abstract
Abstract Triazolopyridine dyes of the formula ##STR1## where one of the two radicals A and E is nitrogen and the other is a radical of the formula C-R 1 , where R 1 is unsubstituted or substituted C 1 -C 20 -alkyl, unsubstituted or substituted phenyl or unsubstituted or substituted mercapto, Q is a radical of the formula ##STR2## where R 2 is a carbocyclic or heterocyclic radical, R 3 is unsubstituted or substituted C 1 -C 4 -alkyl, C 1 -C 4 -alkoxycarbonyl or unsubstituted or substituted phenyl, R 4 is cyano, carbamoyl, carboxyl, C 1 -C 4 -alkoxycarbonyl or benzothiazolyl or R 3 and R 4 together are the remainder of a fused-on benzene ring and X is CH or nitrogen, and R 5 is oxygen or a radical of a compound with an acidic CH, and a process for the thermal transfer of these dyes.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
220 words
A triazolopyridine dye of the formula I ##STR86## where A is nitrogen, E is a radical of the formula C-R 1 , where R 1 is C 1 -C 20 -alkyl which is unsubstituted or substituted and may be interrupted by 1 to 4 oxygen atoms in ether functionality, unsubstituted or substituted phenyl, mercapto or unsubstituted or substituted C 1 -C 20 -alkylthio, Q is a radical of the formula ##STR87## where R 2 is a 5- or 6-membered carbocyclic or heterocyclic radical which may be benzo-fused, R 3 is C 1 -C 4 -alkyl which may be interrupted by an oxygen atom in ether functionality, C 1 -C 4 -haloalkyl, C 1 -C 4 -alkoxycarbonyl or unsubstituted or substituted phenyl, R 4 is cyano, carbamoyl, carboxyl, C 1 -C 4 -alkoxycarbonyl or benzothiazolyl or R 3 and R 4 together are the remainder of a fused-on benzene ring and X is CH or nitrogen, and R 5 is oxygen or a radical of the formula ##STR88## where L is in each case C 1 -C 8 -alkyl which may be interrupted by 1 or 2 oxygen atoms in ether functionality, or unsubstituted or substituted phenyl, with the proviso that when Q is a radical of the formula ##STR89## the two radicals A and E may also be mutually interchanged.
