Zusammenfassung:Color photographic material comprising red-, green- and blue-sensitive silver halide emulsion layers containing respectively at least two cyan couplers, at least one magenta coupler and at least one yellow coupler comprises a 3,4-dichlorobenzamide derivative (I) and a 3,5-dichlorobenzamide derivative (II) as cyan couplers. Color photographic material comprising red-, green- and blue-sensitive silver halide emulsion layers containing respectively at least two cyan couplers, at least one magenta coupler and at least one yellow coupler comprises a 3,4-dichlorobenzamide derivative of formula (I) and a 3,5-dichlorobenzamide derivative of formula (II) as cyan couplers making up at least 20 wt.% of the total amount of cyan couplers in the red-sensitive layer.
