(57) [Summary] (with correction) [PROBLEMS] To sufficiently satisfy various conditions in a sublimation transfer system as a heat-sensitive transfer system, suitable for use in a heat-sensitive transfer, and exhibit a particularly excellent cyan color and its light fastness. The present invention provides a thermal transfer dye excellent in heat resistance, and a thermal transfer ink and a thermal transfer sheet using the same. SOLUTION: The thermal transfer dye comprising an azo compound represented by the following general formula (I), and the thermal transfer dye, a thermal transfer ink containing a binder and an organic solvent, and A heat-sensitive transfer sheet comprising a support, on which a color material layer containing the dye for heat transfer and a binder is formed. |
