    摘要： A photographic element comprising a light sensitive silver halide emulsion sensitized with a dye of formula (I) and a nucleating agent or amine booster associated with the silver halide emulsion: ##STR1## wherein: R.sub.3 is an alkyl group, alkenyl group, or aryl groupR.sub.4 and R.sub.5 are each hydrogen, an alkyl group, alkenyl or aryl group;R.sub.6, R.sub.7 and R.sub.8 are, independently, an alkyl group, alkenyl group, aryl group, or H;the dye has at least three acid or acid salt substituents; andeach L independently represents a methine group;p is 0 or 1;Z.sub.1 represents the atoms necessary to complete a 5- or 6-membered heterocyclic ring group;(X).sub.n represents counterions as needed to balance the charge on the molecule.The present invention also provides a process for forming a high contrast photographic image on a photographic element having a light sensitive silver halide emulsion sensitized with a dye of formula (I). The process comprises developing such a photographic element in the presence of a hydrazine compound and an amine booster.

    摘要： 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.
