Abstract:
A photographic element comprised of a support and coated on the support at least one emulsion layer comprised of(a) radiation-sensitive silver halide grains,(b) sensitizer for the radiation-sensitive silver halide grains,(c) hydrophilic colloid vehicle, including peptizer for the radiation-sensitive silver halide grains, and(d) light scattering particles,wherein(a) the radiation-sensitive silver halide grains include tabular grains (1) having an aspect ratio of at least 2.0, (2) having {111} major faces, (3) containing greater than 50 mole percent bromide, based on silver, and (4) accounting for greater than 50 percent total grain projected area,(b) the sensitizer includes a fragmentable electron donating sensitizer,(c) the peptizer is a water dispersible cationic starch, and(d) the light scattering particles have aspect ratios of less than 1.5 and can be dissolved for removal from the emulsion layer.
