PROBLEM TO BE SOLVED: To provide an emulsification dispersion composition which shows excellent dispersion stability and is used for stably manufacturing a heat- sensitive recording material having a good performance. SOLUTION: This emulsification dispersion composition to be used for manufacturing the heat-sensitive recording material is obtained by dispersedly emulsifying an oil phase containing a chemical compound which shows that its dispersion and transmission volume (dispersion rate) in an aqueous polyvinyl alcohol solution of such a volume measuring a thickness of 100 μm and a diameter of 20 mm for 300 hours is 0.0001 g or less and has a color developing function to an electron donative dye precursor and also an organic solvent, in a water phase. In addition, the heat-sensitive recording material is manufactured using the emulsification dispersion composition. |
