Abstract: Radiation-cleavable nondiffusible compounds for providing a transfer dye image are comprised of a spectral sensitizing dye moiety and a diffusible image dye moiety joined by a linkage in the spectral sensitizing dye moiety which is cleaved upon absorption of radiation by the spectral sensitizing dye moiety, thereby releasing a diffusible image dye. Such compounds are useful in radiation-sensitive elements and processes to provide dye images. Preferred compounds have the formula ##STR1## where: Q represents the atoms to complete a pyridine or quinoline ring;SENS is attached to the 2 or 4 position of the pyridine or quinoline ring and represents the atoms which, in conjunction with N, complete a spectral sensitizing dye;ALK represents an alkylene moiety of 1 to 8 carbon atoms;DYE represents a diffusible photographic dye or dye precursor moiety; andX.sup..crclbar. represents an anion, if necessary to provide charge neutrality.
