Abstract:
1. A silver halide color reversal photographic material 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 when exposed and processed in accordance with the following processing to obtain a characteristic curve based on status A density, the photographic material 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 meets the following requirement: Processing: wherein the following processing solutions are used: and wherein IIEs and IIEh are interimage effect characteristic values at a density of 2.0 and 0.4 respectively, and are defined according to the following equations: wherein when the photographic material is exposed to each of blue, green, red, yellow, magenta and cyan light for 1/100 sec. using a white light source of 5400 K and a blue gelatin filter, a green gelatin filter, a red gelatin filter, a yellow gelatin filter, a magenta gelatin filter, and a cyan gelatin filter and processed according to the foregoing processing to obtain characteristic curves based on status A density and to determine an exposure amount (Es) giving a density of 2.0 and an exposure amount (Eh) giving a density of 0.4 on the characteristic curves for each of the blue-sensitive layer, the green-sensitive layer and the red-sensitive layer, characteristic values of interimage effects at densities of 2.0 and 0.4, represented by IIEs(BG), IIEs(BR), IIEs(GB), IIEs(GR), IIEs(RB) and IIEs(RG); IIEh(BG), IIEh(BR), IIEh(GB), IIEh(GR), IIEh(RB) and IIEh(RG) are defined as follows; wherein Es(Y(G)) and Eh(Y(G)) represent exposure amounts giving densities of 2.0 and 0.4 of the green-sensitive layer, respectively, when exposed through the yellow gelatin filter; Es(B′(G)) and Eh(B′(G)) represent exposure amounts giving densities of 2.0 and 0.4 of the green-sensitive layer, respectively, when exposed through the blue gelatin filter; Es(Y(R)) and Eh(Y(R)) represent exposure amounts giving densities of 2.0 and 0.4 of the red-sensitive layer, respectively, when exposed through filter the yellow gelatin filter; Es(B′(R)) and Eh(B′(R)) represent exposure amounts giving densities of 2.0 and 0.4 of the red-sensitive layer, respectively, when exposed through the blue gelatin filter; Es(M(B)) and Eh(M(B)) represent exposure amounts giving densities of 2.0 and 0.4 of the blue-sensitive layer, respectively, when exposed through the magenta gelatin filter; Es(G′(B)) and Eh(G′(B)) represent exposure amounts giving densities of 2.0 and 0.4 of the blue-sensitive layer, respectively, when exposed through the green gelatin filter; Es(M(R)) and Eh(M(R)) represent exposure amounts giving densities of 2.0 and 0.4 of the red-sensitive layer, respectively, when exposed through the magenta gelatin filter; Es(G′(R)) and Eh(G′(R)) represent exposure amounts giving densities of 2.0 and 0.4 of the red-sensitive layer, respectively, when exposed through the green gelatin filter; Es(C(B)) and Eh(C(B)) represent exposure amounts giving densities of 2.0 and 0.4 of the blue-sensitive layer, respectively, when exposed through the cyan gelatin filter; Es(R′(B)) and Eh(R′(B)) represent exposure amounts giving densities of 2.0 and 0.4 of the blue-sensitive layer, respectively, when exposed through the red gelatin filter; Es(C(G)) and Eh(C(G)) represent exposure amounts giving densities of 2.0 and 0.4 of the green-sensitive layer, respectively, when exposed through the cyan gelatin filter; Es(R′(G)) and Eh(R′(G)) represent exposure amounts giving densities of 2.0 and 0.4 of the green-sensitive layer, respectively, when exposed through the red gelatin filter.
