Abstract:
A multilayer silver halide color photographic element 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 ##STR87## wherein COUP is a magenta dye-forming coupler having the azo group attached to its coupling position;ARYL represents an aromatic group;m represents an integer of from 1 to 4;each L.sup.1 represents a divalent linking group;each k is either 0 or 1;each L.sup.2 represents --NHSO.sub.2 --, NHCO--, --SO.sub.2 NH--, or --CONH--;each Z represents --SO.sub.3 M or --PO.sub.3 M, where M represents H or a counter ion; andn represents an integer of from 1 to 5;with the provisos that when at least one L.sup.1 or L.sup.2 group comprises an --NHSO.sub.2 -- or --SO.sub.2 NH-- group then the total number of Z group substituents on the coupler is at least 2, and when no L.sup.1 or L.sup.2 group comprises an --NHSO.sub.2 -- or --SO.sub.2 NH-- group then the total number of Z group substituents on the coupler is at least 3, and if k is 0 for a substituent on the ARYL group then the L.sup.2 group for that substituent is either --NHSO.sub.2 -- or --NHCO--.
