ABSTRACT:
A photographic element is disclosed comprised of a support and, coated on the support, at least one radiation-sensitive layer. The radiation-sensitive layer contains silver halide grains including a spectral sensitizer adsorbed on the surface thereof and, intimately admixed therewith, silver halide grains free of surface spectral sensitization and having a particle size in the range of 0.15 to 0.8 micron in diameter. The photographic element exhibits improved speed without a concurrent increase in graininess.
