Color photographic materials are disclosed having red-, green- and blue-sensitive silver halide emulsion layer units, which units contain faster and slower emulsion layers for each color sensitivity. In such materials it has been found that increased speed can be obtained by manufacturing the material so that, upon imagewise exposure, light strikes the relatively faster green- and red-sensitive layers before passing to the slower green- and red-sensitive layers, but after penetrating the blue-sensitive layer(s).

In a multilayer, multicolor photographic element comprising a support having coated thereon dye-forming, hydrophilic colloid-containing silver halide emulsion layers which are spectrally sensitized to different regions of the!visible spectrum, said element being comprised of at least one blue-sensitive emulsion layer, a yellow filter layer underlying said blue-sensitive layer, a plurality of green-sensitive silver halide emulsion layers and a plurality of red-sensitive silver halide emulsion layers; one of said green-sensitive emulsion layers being a faster green-sensitive layer and exhibiting a faster photographic speed than that of at least one other of said green-sensitive emulsion layers and one of said red-sensitive emulsion layers being a faster red-sensitive layer and exhibiting a faster photographic speed than that of at least one other of said red-sensitive emulsion layers; the improvement comprising said faster green-sensitive emulsion layer and said faster red-sensitive emulsion layer being located in adjacent relationship to form a faster emulsion unit, said one other, slower, green-sensitive emulsion layer and said one other, slower, red-sensitive emulsion layer being located in adjacent relationship to form a slower emulsion unit, said slower emulsion unit being located between said faster emulsion unit and said support, in each of said faster emulsion unit and said slower emulsion unit, said red-sensitive layer being positioned closer than said green-sensitive layer to said support, and said blue-sensitive layer or layers being farther from the support than said faster emulsion unit.
