    摘要: 1-PHTHALAZINONE AND 1-PHTHALAZINONE DERIVATIVES OF THE FOLLOWING FORMULA: ##STR1## wherein R.sup.1 represents a hydrogen atom, an alkyl group, an aralkyl group, an acyloxyl group, an alkoxyl group, a halogen atom, a nitro group, an amino group or an amido group; and R.sup.2 represents a hydrogen atom, an alkyl group or an aryl group. Such can be prepared at good yields by the reaction of a benzoic acid derivative of the following formula: ##STR2## wherein R.sup.1 has the same meanings as defined above; X represents a halogen atom; and Y represents a hydroxyl group, an alkoxyl group or a halogen atom; with hydrazine or a hydrazine derivative of the following formula:R.sup.2 -- NH -- NH.sub.2 (III)wherein R.sup.2 has the same meanings as defined above.

    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.
