摘要： A color reversal photographic element is disclosed comprising a support having coated thereon a silver halide emulsion layer comprising a silver halide emulsion chemically sensitized in the presence of an organomercapto Au(I) complex having the formula [L—Au—L]M wherein M is a cationic counter ion and each L is an organomercapto ligand which has antifogging, stabilizing or sensitizing properties, and a rapid sulfiding agent represented by structure SS-1 wherein each of the R1, R2, R3, and R4 groups independently represents an alkylene, cycloalkylene, carbocyclic arylene, heterocyclic arylene, alkarylene or aralkylene group; or taken together with the nitrogen atom to which they are attached, R1 and R2 or R3 and R4 can complete a 5- to 7-membered heterocyclic ring; and each of the B1, B2, B3, and B4 groups independently is hydrogen or represents a carboxylic, sulfinic, sulfonic, hydroxamic, mercapto, sulfonamido or primary or secondary amino nucleophilic group, with the proviso that at least one of the B1R1 to B4R4 groups contains the nucleophilic group bonded to a urea nitrogen atom through a 1- or 2-membered chain. The use of the combination of the two classes of sensitizers of the present invention makes it possible to sensitize the silver halide emulsions employed in color reversal elements at a wider range of temperature. This robustness to temperature translates to less variable performance of the silver halide emulsion. Additionally, the use of individual gold and sulfur sensitizers advantageously makes it possible to sensitize silver halide reversal photographic elements such that the sulfur to gold ratio can be varied independently.

摘要： Radiation sensitive emulsions are disclosed comprised of silver iodochloride grains having three pairs of equidistantly spaced parallel {100} crystal faces and containing from 0.05 to 3 mole percent iodide, based on total silver, in a controlled, non-uniform iodide distribution forming a core containing at least 50 percent of total silver, a surface shell, and a sub-surface shell that contains a maximum iodide concentration and provides, when the emulsion is exposed to 390 nm electromagnetic radiation at 10.degree. K., stimulated fluorescent emissions in the range of from 450 to 470 nm and at 500, the stimulated fluorescent emission in the range of from 450 to 470 nm having a peak intensity more than twice the stimulated fluorescent emission intensity at 500 nm. The emulsion is prepared by a process wherein a) grains accounting for at least 50 percent of total silver forming the silver iodochloride grains are grown in the dispersing medium, (b) while employing the grains as substrates for further grain growth, locating crystal lattice variances in the grains by the incorporation of iodide to form a first shell having a higher local iodide concentration than any other grain portion, and (c) precipitating silver chloride onto the surface of the grains formed in step (b) to create a surface shell separating the first shell from the surface of the completed grains.
