The invention relates to a photographic element comprising an emulsion layer comprising a cyan dye forming coupler, an emulsion layer comprising a magenta dye forming coupler, an emulsion layer comprising a yellow dye forming coupler wherein said magenta coupler comprises ##STR1## wherein R.sub.a and R.sub.b independently represent H or a substituent; X is hydrogen or a coupling-off group; and Z.sub.a, Z.sub.b, and Z.sub.c are independently a substituted methine group, .dbd.N--, .dbd.C--, or --NH--, provided that one of either the Z.sub.a --Z.sub.b bond or the Z.sub.b --Z.sub.c bond is a double bond and the other is a single bond, and when the Z.sub.4 --Z.sub.c bond is a carbon-carbon double bond, it may form part of an aromatic ring, and at least one of Z.sub.a, Z.sub.b, and Z.sub.c represents a methine group connected to the group R.sub.b, and wherein between said yellow dye forming layer and said magenta dye forming layer, there is located at least one enhancer layer substantially free of silver halide comprising gelatin and said yellow dye forming coupler.
A photographic element comprising an emulsion layer comprising a cyan dye forming coupler, an emulsion layer comprising a magenta dye forming coupler, an emulsion layer comprising a yellow dye forming coupler wherein said magenta coupler is selected from the group consisting of P-1 and P-2 ##STR12## wherein R.sub.a and R.sub.b independently represent H or a substituent;
A method of forming a photographic image comprising, providing a photographic element, said photographic element comprises an emulsion layer comprising a cyan dye forming coupler, an emulsion layer comprising a magenta dye forming coupler, an emulsion layer comprising a yellow dye forming coupler wherein said magenta coupler is selected from the group of P-1 and P-2wherein R.sub.a and R.sub.b independently represent H or a substituent;
