ABSTRACT:
A color reversal photographic element comprises a support bearing a red-sensitive, cyan dye-forming unit, a green-sensitive, magenta dye-forming unit, and a blue-sensitive, yellow dye-forming unit, each unit comprising a photosensitive silver halide layer and an image-dye forming coupler; the element contains an interimage effect-controlling means which is characterized as having the capability of simultaneously forming a red image of high relative chroma and a yellow-red tint image of substantially lower relative chroma when the element is exposed to a red color standard object having CIELab values for D.sub.55 reference white a*=30.46, b*=19.16, C*=35.98, L*=40.12 and a yellow-red tint color standard object having CIELab values for D.sub.55 reference white a*=17.26, b*=18.01, C*=24.95, L*=66.98; the resulting images have a red reproduction coefficient equal to or greater than 0.88 and a ratio of red reproduction coefficient to yellow-red tint reproduction coefficient equal to or greater than 1.15.
