ABSTRACT OF THE DISCLOSURE A recording process including image stabilization com- prising the steps of : (1) image-wise exposing to active electromagnetic radia- tion of a recording material containing in a recording layer a aye precursor compound and at least one photosensitive organic polyhalogen compound capable of producing photoradi- cals and a dyestuff with said dye precursor compound when exposed with ultraviolet radiation and/or visible light, and (2) heating the photoexposed recording material thereby transforming the non-decomposed polyhalogen compound into a non-photosensitive substance by reaction with at least one stabilizing substance selected from the group consisting of triphenylamine. a soft base containing an element of the group consisting of phosphorus, arsenic, antimony, bismuth, selenium, and tellu- rium, and an .alpha.,.beta.-ethylenically unsaturated compound in which at least the .alpha.-carbon atom of at least one ethylene group is linked to cyano, a cyanomethyl group, an acyl group, an acyloxy group, an alkoxycarbonyl group, a carbamoyl group or an aryl group, said stabilizing substance(s) being available in a layer adjacent to the recording layer for allowing on heating the reaction with non-photo-decomposed polyhalogen compound.
