发明名称 Color photographic recording material having elevated sensitivity and improved color reproduction
摘要 A color photographic recording material having a film support and, arranged thereon, at least one red-sensitive silver halide emulsion layer containing a cyan coupler, at least one green-sensitive silver halide emulsion layer containing a magenta coupler, at least one blue-sensitive silver halide emulsion layer containing a yellow coupler and optionally further non-photosensitive layers contains, in addition to conventional sensitizing dyes, in at least one of the red-sensitive silver halide emulsion layers thereof and in at least one of the green-sensitive emulsion layers thereof at least one cyanine dye in each layer having an absorption maximum in a methanolic solution in the range from 515 to 550 nm, wherein the absorption maxima of the additional cyanine dye in the red-sensitive silver halide emulsion layer and of the additional cyanine dye in the green-sensitive layer, in each case measured in a methanolic solution, are no more than 10 nm and preferably no more than 5 nm apart. In a preferred embodiment, the additional cyanine dye in the red-sensitive silver halide emulsion layer is identical to the additional cyanine dye in the green-sensitive silver halide emulsion layer. The recording material exhibits improved sensitivity and improved color reproduction.
