Provided is a thermal recording material that is excellent in thermal response and retainability of an image portion and which generates fewer residues adhering to the thermal head of a thermal printer. The thermal recording material having a thermal recording layer comprising a generally colorless or light-colored electron-donating dye precursor and an electron-accepting developer that reacts under heat to cause said dye precursor to form a color, said thermal recording layer containing a specific diphenylsulfone derivative, a specific amide derivative and a specific fluorane derivative, wherein the weight ratio of the specific diphenylsulfone derivative above and the specific amide derivative above is 2/1 to 1/2.
