ABSTRACT:
A novel photographic development inhibitor releasing coupler (A) comprises a coupler moiety bonded to at least one timing group that enables timing of release of a releasable development inhibitor moiety wherein the releasable development inhibitor moiety contains a --CH.sub.2 --Q group that is bonded directly to the inhibitor moiety and that is a group enabling, upon exposure and processing of a photographic element containing the coupler, reduced interlayer interimage effect without reduced image acutance. The coupler (A) is useful in a color photographic silver halide element and process.
