Abstract: A photosensitive recording material, which comprises a support bearing a layer containing at least one photosensitve organic polyhalogen compound producing free radicals upon exposure to ultraviolet and/or visible light, a dye precursor, which by the action of said free radicals is capable of forming a dye, and a thermally activatable stabilizing substance within the scope of the following general formula: ##STR1## wherein: X represents1. an aryl group including a substituted aryl group, or2. the group --OR.sup.1 in which R.sup.1 is an aryl group including a substituted aryl group,3. the group --CH.dbd.CH--R.sup.2 in which R.sup.2 is an aryl group including a substituted aryl group, or4. the group ##STR2## in which R.sup.3 stands for hydrogen, an alkyl group, or cycloalkyl group, an aryl group including a substituted aryl group and in which R.sup.4 stands for an alkyl group, a cycloalkyl group, or an aryl group including a substituted aryl group, or R.sup.3 and R.sup.

Abstract: A photographic process in which a photographic material containing in a layer on a support a mixture of the following compounds:1. at least one ultraviolet-sensitive organic polyhalogen compound capable of producing a dye salt with a spiropyran compound on exposure with ultraviolet radiation,2. at least one spirobi(arylpyran) compound,3. N-vinylcarbazole,4. at least one compound selected from the group consisting of furan, furylacrylic acid and 2-carboxyfuran,5. at least one compound selected from the group consisting of 1-phenyl-3-pyrazolidinone, benzalphenylhydrazone and 1,5-dimethyl-2-phenyl-4-pyrazolin-3-one, and6. a polymeric compound containing N-vinylcarbazole units,Is image-wise exposed to ultraviolet radiation of an intensity sufficient to produce a print-out image and the exposed material is heated to stabilize the image and to increase its spectral density in the three primary color spectral regions.
