| titleOfInvention | Color photographic elements containing yellow-colored magenta dye-forming masking couplers |
| abstract | A multilayer silver halide color photographic element is disclosed comprising a support bearing a light-sensitive silver halide emulsion layer and a non-diffusible yellow-colored magenta dye-forming masking coupler of the following formula wherein COUP is a magenta dye-forming coupler having the azo group attached to its coupling position; q is an integer of from 0 to 3, and each R' independently represents a substituent group or two R' groups together complete a ring of from 5-7 atoms, which ring may include 1 or more heteroatoms selected from O, N and S; m is 1 or 2, and DG represents a substituent of the formula where each L1 represents a divalent linking group, preferably -O(CH2)y-, -NHCO(CH2)y-, or -NRCO(CH2)y-, where R represents an alkyl or aryl group and y represents an integer from 1 to 4; each k is either 0 or 1; each L2 represents -NHSO2-, -NHCO-, -SO2NH-, or -CONH-, preferably at least one L2 group being -NHSO2- or -SO2NH-, more preferably -NHSO2-; each Z represents -SO3M or -PO3M, where M represents H or a counter ion such as Na, K, Li, or NH4; and each n represents an integer of from 1 to 5; with the provisos that each DG substituent group, when present, is located in the 4- or 6-position meta to the 2-hydroxyl substituent on the arylazo group, and that when at least one L1 or L2 group comprises an -NHSO2- or -SO2NH- group then the total number of Z group substituents on the coupler is at least 2, and when no L1 or L2 group comprises an -NHSO2- or -SO2NH- group then the total number of Z group substituents on the coupler is at least 3, and if k is 0 for a DG substituent group then the L2 group for that DG substituent is either -NHSO2- or -NHCO-. |
