Abstract
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).
