ABSTRACT:
Multicolor photographic elements are disclosed each containing superimposed emulsion layers for separately recording blue and minus blue light including at least one emulsion layer comprised of a dispersing medium and silver halide grains, wherein at least 50 percent of the total projected area of the silver halide grains is provided by thin tabular silver iodide grains having a thickness of less than 0.3 micron and an average aspect ratio of greater than 8:1. The multicolor photographic elements show advantages in the minus blue recording emulsion layers directly attributable to the thin tabular silver iodide grains.
