PROBLEM TO BE SOLVED: To develop a heat sensitive recording material, which has a few texture fogging, a high sensitivity and, at the same time, is excellent in the storage stability of a color developed image made thereof. SOLUTION: In the heat sensitive recording material formed by providing a heat sensitive color developing layer mainly including a normally colorless or light-colored color forming compound, a color developing compound allowing to develop color in the color forming compound under heat and a sensitizer on a support, a bis(3-allyl-4-hydroxyphenyl)sulfone having an α-type crystal form is included as the color developing compound and a dibenzoyl methane is included as the sensitizer. |
