(57) Abstract: An object of the present invention is to provide a halogen radical releasing agent which has excellent storage stability and rapidly releases a halogen radical. A second object is to provide a heat-developable photographic light-sensitive material having good raw storability and an image forming method thereof. The third object is to provide a heat-developable photographic material for a laser imager for medical use, which has good raw storability and image storability, and a good color tone of image silver, or a high contrast agent, and An object of the present invention is to provide a photothermographic material for output of a printing imagesetter having an oscillation wavelength of 800 nm, and an image forming method thereof. SOLUTION: The halogen radical releasing agent characterized in that a chemical structure is changed by being oxidized. |
