Abstract
A color photographic element which comprises a light sensitive silver halide emulsion layer and a non-light sensitive interlayer containing a ballasted 5-carbamoyl-1,3-dihydroxybenzene compound. The element exhibits an improved ability to prevent oxidized developer from diffusing away from the imaging layer in which it formed and into other color records where it can form the wrong color dye.
