Abstract

Abstract A color photographic material composed of a support having 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, wherein with respect to helium-cadmium laser light having a wavelength of 441.6 nm, the ratio of the sensitivity of the green-sensitive emulsion layer to that of the blue-sensitive emulsion layer and the ratio of the sensitivity of the red-sensitive emulsion layer to that of the blue-sensitive emulsion layer are not more than 0.10; with respect to argon laser light having a wavelength of 514.5 nm, the ratio of the sensitivity of the blue-sensitive emulsion layer to that of the green-­sensitive emulsion layer and the ratio of the sensitivity of the red-sensitive emulsion layer to that of the green-sensitive emulsion layer are not more than 0.10; and with respect to helium-neon laser light having a wavelength of 632.8 nm, the ratio of the sensitivity of the blue-sensitive emulsion layer to that of the red-­sensitive emulsion layer and the ratio of the sensitivity of the green-sensitive emulsion layer to that of the red-sensitive emulsion layer are not more than 0.10. The color photographic material is useful for recording laser images, such as video iamges, with reduced color mixing.
