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.
