ABSTRACT:
Color photographic material is described in which a yellowish image is formed which can be used to print black and white prints. Also present in the layer is a small amount of a more reactive coupler which produces a colored image to which black and white paper is not sensitive. This more reactive coupler reduces the fog in the highlight areas.
Most preferably small amounts of other couplers are present which result in a green or brown image which makes it easier for the operator to focus the image.
