发明名称 Photographic material and process comprising a universal coupler
摘要 <p>A photographic coupler (A) capable, upon oxidative coupling, of forming a dye that can be washed out of a photographic element containing the coupler upon processing, comprises, in the coupling position, a coupling-off group that comprises, in sequence, a releasable ballasted carbamate timing group and a releasable benzotriazole, triazole or tetrazole development inhibitor group. Such a coupler is useful in photographic silver halide materials and processes to provide improved images.</p>
