A heat-sensitive recording material has a support and a color-developing layer which comprises both as a colorless basic chromogenic dye at least one of a particular fluorane-type leuco dye and a particular divinyl compound and as a stabilizer a particular halogen-substituted zinc benzoate derivative. This heat-sensitive recording material is superior in light resistance, weather resistance, oil resistance and optical readability in the near infrared region.
