Diphenylsulfone bridged compounds of the general formula: (1) wherein n is an integer of 1. to 10. Further, there is disclosed a thermal recording material comprising a support and, superimposed thereon, a thermosensitive color forming layer containing a color forming substance for thermal recording consisting of any of the diphenylsulfone bridged compounds and a color forming substance consisting of a colorless or light-colored leuco dye. This thermal recording material excels in the storability, especially wet heat resistance and oil resistance, of image areas and further exhibits excellent characteristics in the storability, especially heat resistance, of undeveloped areas.
