Photographic material and process comprising a coupler capable of forming a wash-out dye |
| abstract |
A photographic element comprises a support bearing at least one photographic silver halide emulsion layer and at least one naphtholic 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 - Rel¹ - T¹ - INH n n n nwherein: n X is selected from oxygen, nitrogen or sulfur; n Rel¹ contains a ballast and is a releasing group for releasing T¹-INH from Rel¹ by intramolecular displacement reaction during photographic processing without substantial delay of releasing; n T¹ is a timing group that releases INH by elimination electron transfer reaction with timing delay during photographic processing; 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. |
