Abstract
A silver halide color reversal light-sensitive material comprising on a transparent support having a red-sensitive silver halide emulsion layer containing a cyan coupler, a green-sensitive silver halide emulsion layer containing a magenta coupler, and a blue-sensitive silver halide emulsion layer containing a yellow coupler is disclosed, wherein the light-sensitive material has a magnetic recording layer containing from 4.times.10.sup.-3 to 3 g/m.sup.2 of a ferromagnetic powder, and the minimum density area of the light-sensitive material after development processing has a chromaticity having an a* value of from -5 to 5, a b* value of from -5 to 5, and an L* value of not less than 80 as calculated from tristimulus values in CIE 1964 X.sub.10 Y.sub.10 Z.sub.10 Colorimetric System under an illuminant C as specified in JIS Z8720 according to the method of JIS Z8729. The photographic material exhibits improved color reproducibility. The present invention further concerns with a light-shut film unit having the silver halide color reversal light-sensitive material packed in a cartridge, the material having a film leader which is inside of the cartridge.
