PURPOSE: To enable an image with high density and high resolution to be thermally printed with low energy, by a method wherein a fine thermally conductive powder is uniformly dispersed in a heat-resistant base to obtain a fixed thermal conductivity, and an ink comprising a sublimable dye dispersed in a binder is applied to the base.
CONSTITUTION: A fine powder having relatively favorable thermal conductivity represented by conductive carbon, graphite, boron nitride, silicon nitride, beryllia, magnesium oxide, aluminum oxide, nickel, aluminum, copper, silver or the like is uniformly dispersed in the heat-resistant base, e.g., a heat-resistant plastic base to obtain a thermal conductivity of 0.3W5kcal/m.h.°C (cal/m.h.°C refers to calory required for raising temperature by 1°C per 1m in 1hr), and an ink comprising a sublimable dye dispersed in a binder is applied to the base. Further, if required, a fine powder having a high thermal conductivity is uniformly dispersed in the binder of the ink together with the dye to enhance the thermal conductivity of the ink to 0.3W5kcal/m.h.°C.
