Abstract:
A photographic element containing a light-sensitive silver-halide emulsion layer having associated therewith a coupler represented by Formula I:COUP-(T)mâ€”L-DYEâ€²â€ƒâ€ƒ(I) whereinCOUP is a photographic coupler residue capable of coupling with oxidized color developer to form a first cyan dye; T is a timing group; m is an integer from 0 to 2; L is a linking group selected from the group consisting of â€”OC(&boxH;O)â€”, â€”OC(&boxH;S)â€”, â€”SC(&boxH;O)â€”, and â€”SC(&boxH;S)â€”, wherein T, when m is not 0, or L, when m is 0, is attached to the coupling site of COUP; and DYEâ€² is group that, upon release from the coupling site, forms a second dye, or dye precursor that is converted to a second dye, which second dye is also cyan colored, which DYEâ€² group is represented by the following formula: â€ƒwherein R2 and R3 are independently organic or inorganic substituents, or a plurality of R2 and/or a plurality of R3 groups can form a saturated, unsaturated, or aromatic carbocyclic or heterocylic ring, the R2 and R3 substituents, and any rings formed thereby, being selected so that the second dye absorbs light predominantly in the range of 600 to 700 nm; n and p are independently an integer from 0 to 4; and Q is O, S, or NRâ€² where Râ€² is H or a substituted or unsubstituted alkyl or aryl group.
