| titleOfInvention | Photographic elements containing new magenta-dye-forming bis couplers |
| abstract | The invention provides new magenta-dye-forming couplers, new magenta dyes formed therefrom, and new photographic elements containing the new couplers. The new couplers have the structure (I): Q-G-Q(I) wherein -G- has the structure (II): -L-NH-SO2-R-SO2-NH-L-(II) wherein -R- is substituted or unsubstituted alkylene, alkoxylene, arylene, or aryloxylene, and each -L- is independently substituted or unsubstituted alkylene, alkoxylene, arylene, aryloxylene, or aryloxyalkylene, and Q- has the structure (III ): <IMAGE> (III) wherein: each R1- is independently H- or a substituent; each X- is independently H- or a coupling-off group; and each of D, E, and Z is independently a substituted or unsubstituted methine group, =N-, or -NH-, with the provisos that one of either the D-E or E-Z bonds is a double bond and the other is a single bond, and when the D-E bond is a carbon-carbon double bond it may form part of an aromatic ring fused with Q-, and one of D, E, and Z is a methine group bonded to -G-. |
