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 to a linkage in the spectral sensitizing dye moiety which is cleaved upon absorption of radiation by the spectal sensitizing dye moiety, thereby releasing the diffusible dye. Such compounds are useful in radiation-sensitive elements and processes.
