PROBLEM TO BE SOLVED: To provide a photosensitive heat-sensitive recording material having high photosensitive properties to a light having a wavelength of 350 to 390 nm and high color developing density of an obtained image. SOLUTION: The photosensitive heat-sensitive recording material comprises a photosensitive heat-sensitive recording layer containing a diazo compound represented by the formula and a coupler, wherein R1 to R5, R9 to R12 are each independently a hydrogen atom, alkyl group, arylic group, alkoxy group, acyl group, carbamoyl group, acylamino group, acyloxy group, oxycarbonyl group or a halogen atom in such a manner that two or more of R1 to R5 may be bonded to form a ring, R6, R7 are each independently a hydrogen atom, alkyl group or aryl group, R8 is an alkyl group or aryl group, and X- is an anion. In the recording material, the diazo compound is preferably included in a microcapsule. |
