ABSTRACT:
A photographic masking coupler containing in the coupling position a coupling-off group that is capable of reacting with oxidized color developing agent to form a water-insoluble dye in non-image areas and a water-soluble compound in image areas of a color photographic element enables formation of a colored integral mask for color correction upon exposure and processing of the element. The masking couplers are essentially colorless in a color photographic element. Such a photographic masking coupler is advantageous in a color photographic element and process.
