摘要:
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 wherein Ra and Rb independently represent H or a substituent; X is hydrogen or a coupling-off group; and Za, Zb, and Zc are independently a substituted methine group, =N-, =C-, or -NH-, provided that one of either the Za-Zb bond or the Zb-Zc bond is a double bond and the other is a single bond, and when the Z4-Zc bond is a carbon-carbon double bond, it may form part of an aromatic ring, and at least one of Za, Zb, and Zc represents a methine group connected to the group Rb, 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.
