摘要： A photographic element comprises a support bearing at least one photographic silver halide emulsion layer and at least one coupler (A) having a water solubilizing group wherein coupler (A) forms a compound that is washed out of the photographic element during photographic processing and forms a coupling-off group represented by the formula:--X--Rel.sup.3 --T.sup.3 --INHwherein;X is selected from oxygen, nitrogen or sulfurX--Rel.sup.3 contains a photographic ballast and is a releasing group for releasing T.sup.3 --INH from X--Rel.sup.3 by intramolecular displacement reaction during photographic processing without substantial delay of releasing;T.sup.3 is a timing group that releases INH by intramolecular displacement reaction with timing delay during photographic processing;INH is a development inhibitor group;The photographic coupler (A) enables formation of easily removable dyes in photographic elements and processes that provide images having improved acutance, stability and interimage effects.
