| titleOfInvention | Photographic material and process comprising a coupler capable of forming a wash-out dye (Q/C) |
| abstract | 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: n n n n -X - Rel⁴ - T⁴ - INH n n n nwherein; n X is selected from oxygen, nitrogen or sulfur; n Rel⁴ contains a ballast and is a releasing group for releasing T⁴-INH from Rel⁴ by elimination electron transfer reaction during photographic processing without substantial delay of releasing; n T⁴ is a timing group that releases INH by intramolecular displacement reaction with timing delay during photographic processing; and n INH is a development inhibitor group. n 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. |
