Silver halide multilayer color photographic material.

摘要

A high sensitivity multilayer color photographic ma­terial is disclosed. The material is comprised of a sup­port base having coated thereon red-sensitive, green-sen­sitive and blue-sensitive silver halide emulsion layers associated with non-diffusing image-forming couplers. The red-sensitive silver halide emulsion layer comprises an upper, an intermediate and a lower silver halide emulsion layer, sensitive to visible light in the same or substan­tially the same spectral wavelength range, with the sen­sitivity of the layers decreasing in order from the upper layer to the lower layer. The green-sensitive silver ha­lide emulsion layer comprises an upper and a lower silver halide emulsion layer, sensitive to visible light in about the same spectral wavelength range, with the sensitivity of the layers decreasing in order from the upper layer to the lower layer. The most sensitive red-sensitive silver halide emulsion layer is arranged between the less sensi­tive and the more sensitive green-sensitive silver halide emulsion layers. The most sensitive red-sensitive silver halide emulsion layer comprises at least one non-diffusing cyan coupler and the more sensitive green-sensitive silver halide emulsion layer comprises at least one non-diffusing magenta coupler, relative coupling rates of said cyan and magenta couplers being higher than couplers forming the same color in the respective layers of lower same-wave­length sensitivity.
