摘要:
A silver halide color reversal photographic material providing images with superior graininess and enhanced sharpness is disclosed, comprising on a support a blue-sensitive silver halide emulsion layer containing a yellow dye forming coupler, a green-sensitive silver halide emulsion layer containing a magenta dye forming coupler and a red-sensitive silver halide emulsion layer containing a cyan dye forming coupler, wherein the photographic material has an ISO speed of 80 or more, and exhibits a gradation (γh) of at least 1.1 within the magenta dye density range of 0.3 to 1.0 on the characteristic curve and a gradation (γs) of at least 1.9 within the magenta dye density range of 1.0 to 2.5 on the characteristic curve and the photographic material satisfies the following requirement of interimage effect characteristic values (IIEh, IIEs): |IIEh|/|IIEs|>1.00
