ABSTRACT:
A silver halide color reversal photographic lightsensitive material comprising a support and, superimposed thereon, at least one red-sensitive silver halide emulsion layer, at least one green-sensitive silver halide emulsion layer and at least one blue-sensitive silver halide emulsion layer, the red-sensitive silver halide emulsion layer having a weight-averaged wavelength (λra) of spectral sensitivity distribution satisfying the relationship: 600 nm<λra<625 nm, which silver halide color reversal photographic lightsensitive material contains at least one interimage effect intensifying layer substantially not forming any image, the interimage effect intensifying layer containing:(a) at least one kind of lightsensitive silver halide grains in an amount of less than 10% in terms of silver quantity based on all the silver halide grains for image formation; and(b) nonlightsensitive silver halide fine grains.
