Abstract
A silver halide color reversal photographic material comprising a support having thereon at least one cyan coupler-containing red-sensitive silver halide emulsion layer, at least one magenta coupler-containing green-sensitive silver halide emulsion layer, and at least one yellow coupler-containing blue-sensitive silver halide emulsion layer, wherein the total light-sensitive silver halide grains in the photographic material have an average silver iodide content of 5.5 mol % or less, and said at least one of light-sensitive silver halide emulsion layers and a substantially light-insensitive hydrophilic colloidal layer adjacent thereto comprises means for producing an interimage effect, said interimage effect satisfying at least one of relationships (a) and (b): PA1 (a) EQU 0.20.ltoreq..DELTA.logE(R.sub.0.5).ltoreq.0.40, EQU 0.ltoreq..DELTA.logE(R.sub.1.5).ltoreq.0.07, and EQU 0.18.ltoreq..DELTA.logE(R.sub.0.5)-.DELTA.logE(R.sub.1.5).ltoreq.0.35 PA1 (b) EQU 0.25.ltoreq..DELTA.logE(G.sub.0.5).ltoreq.0.45, EQU 0.ltoreq..DELTA.logE(G.sub.1.5).ltoreq.0.15, and EQU 0.23.ltoreq..DELTA.logE(G.sub.0.5)-.DELTA.logE(G.sub.1.5).ltoreq.0.35 wherein .DELTA.logE(R.sub.0.5) and .DELTA.logE(R.sub.1.…
