ABSTRACT:
A color photographic element is disclosed containing in its blue recording layer unit a blue light reflective layer positioned to receive light from a layer in the blue recording layer unit containing latent image forming silver halide grains of maximum sensitivity. The blue light reflective layer is free of blue absorbing dye and contains tabular silver halide grains having a thickness in the range of from 0.12 to 0.15 .mu.m, an average aspect ratio of greater than 15, and a coating coverage of 0.5 to 1.5 g/m.sup.2, and are formed of greater than 50 mole percent bromide, based on silver. The layer containing grains of maximum sensitivity additionally contains from 0.01 to 0.5 g/m.sup.2 of randomly oriented grains having an ECD in the range of from 0.01 to 0.5 .mu.m.
