发明名称 Color photographic silver halide material
摘要 A color photographic silver halide material, which has a support which comprises at least one blue-sensitive, yellow-coupling silver halide emulsion layer nearest the light source and at least one green-sensitive, magenta-coupling silver halide emulsion layer and at least one red-sensitive, cyan-coupling silver halide emulsion layer which are further from the light source than is the at least one blue-sensitive layer, and which contains at least one cyan masking coupler which has its maximum absorption above 650 mn, the red-sensitive layers have their maximum sensitivity at 620±20 nm and the absorption of the masking coupler at the maximum sensitivity of the red-sensitive layers is at most 70% of its absorption at 690 mn, is distinguished by improved color reproduction and color saturation in the magenta layer without loss of sensitivity.
