摘要： A heat developable light-sensitive material comprising a support having thereon at least one light-sensitive layer containing (1) an oxidation-reduction image-forming combination of (a) a silver salt oxidizing agent and (b) a reducing agent and (2) a catalytic amount of a light-sensitive silver halide or a compound capable of reacting with the silver salt (a) to form a light-sensitive silver halide, the light-sensitive layer further containing (3) at least one specific phthalazinone compound. The development of the above light-sensitive material is carried out simply by heating the material at a temperature of about 90.degree. to 180.degree. C. for 1 to 60 seconds after imagewise exposure. An image of black tone can be obtained without contaminating the developing machine.

摘要： Two components consisting of an organic halogen compound generating halogen containing free-radicals and/or halogen ions due to the action of radiation and a color generator reacting with the thus generated halogen containing free-radicals and/or halogen ions to form a visible image are subjected to dispersion in the form of discrete globules in a hydrophilic binder, and the thus dispersed mixture is applied on a suitable support to thereby obtain a recording material. The entire surface of the thus obtained recording material is heated prior to the action of the radiation forming the visible color image in a dry treatment. The described process is suitable for image formation by negative-positive working photographic procedures.
