PROBLEM TO BE SOLVED: To provide a photosensitive heat sensitive recording material having excellent storage stability (life storage stability, image preservability) capable of stably forming an image having high whiteness of a skin and an excellent contrast and stably preserving a formed image for a long period. SOLUTION: In the photosensitive heat sensitive recording material comprising a photosensitive heat sensitive recording layer containing at least one type of diazonium and at least one type of coupler for color developing by reacting with the diazonium salt on a support, the recording layer contains a compound represented by formula (wherein R1, R2 are each an alkyl group, or an aryl group, R is an alkyy group, an aryl group, a halogen atom, an alkoxy group, an aryloxy group, an alkoxycarbonyl group, an aryloxycarbonyl group or an acyloxy group, and n is an integer of 0 to 4). |
