HEAT DEVELOPABLE PHOTOSENSITIVE MATERIAL

PROBLEM TO BE SOLVED: To obtain a heat developable photosensitive material that suppresses the emission of a foul odor in heat development by specifying the amount of a solvent contained in a photosensitive material. SOLUTION: It is preferable that the amount of a solvent contained in a heat developable photosensitive material is made as small as possible from the viewpoint of a foul odor, but when the photosensitive material is dried up or nearly dried up, the heat developability deteriorates extremely. The amount of the residual solvent in the photosensitive material is adjusted to 10-100 mg/m3 so as to suppress the emission of a foul odor without deteriorating the heat developability. The amount may be adjusted by reducing the amount of a binder, raising drying temperature or prolonging drying time but the raising of drying temperature is not so favorable because it is accompanied by the increase of fog. The objective heat developable photosensitive material that suppresses the emission of a foul odor in heat development is obtained.
