ABSTRACT:
Improved sensitivity and improved interimage effects are obtained in a multilayer color-photographic recording material having two red-sensitive, two green-sensitive and a blue-sensitive silver halide emulsion layer as well as a yellow filter layer, the more sensitive red-sensitive and the more sensitive green-sensitive layers forming a comparatively more sensitive layer unit arranged further away from the support than each of the less sensitive green-sensitive and the less sensitive red-sensitive layer but nearer to the support than the yellow filter layer underneath the blue-sensitive layer; an additional chloride-containing silver halide emulsion layer of comparatively low sensitivity containing a non-diffusible DIR compound of low reactivity is arranged within the comparatively more sensitive layer unit between the red-sensitive and the green-sensitive layers.
