MULTICOLOR PHOTOGRAPHIC ELEMENT WITH A TABULAR GRAIN EMULSION LAYER OVERLYING A MINUS BLUE RECORDING EMULSION LAYER Abstract of the Disclosure Moderate camera speed photographic elements for producing subtractive primary dye images are disclosed, including one emulsion layer comprised of silver bromide or bromoiodide grains having a mean diameter in the range of from 0.4 to 0.55 µm including tabular grains having an aspect ratio of greater than 8:1 accounting for at least 50 percent of the total projected area of the grains in the emulsion layer and being positioned to receive imaging radiation prior to one or more emulsion layers sensitized to the red or green portion of the spectrum. Enhancement of speed-granularity relationships, blue to minus blue speed separation, silver utilization, and image sharpness can all be realized.
