    Abstract: The invention relates to triazolopyridine dyes of formula (I) where one of the two groups A and E stands for nitrogen and the other stands for a group of formula C-R1, in which R1 stands for optionally substituted C1-C20 alkyl, optionally substituted phenyl or optionally substituted mercapto, Q is a group of formula (i) or (ii) where R2 stands for a carbocyclic or heterocyclic group, R3 stands for optionally substituted C1-C20 alkyl, C1-C4 alkoxycarbonyl or optionally substituted phenyl, R4 stands for cyano, carbamoyl, carboxyl, C1C4 alkoxycarbonyl or benzothiazolyl, or R3 and R4 together stand for the group of a fused benzo ring, and X stands for CH or nitrogen, and R5 signifies oxygen or a group of a CH acid compound. The invention further relates to a process for the heat transfer of these dyes.
