Zusammenfassung:A colour photographic material comprising a transparent support, at least one blue-sensitive, predominantly yellow-coupling silver halide emulsion layer, at least one green-sensitive, predominantly magenta-coupling silver halide emulsion layer (PP-1) and at least one red-sensitive, predominantly cyan-coupling silver halide emulsion layer (BG-1), characterised in that the spectral sensitivity distribution of BG-1 is characterised in that 605 max 630 nm, 0.1 lgE 640 0.6 and 1.8 lgE 680 , wherein max represents the wavelength at which the maximum sensitivity occurs, lgE 640 represents the difference of the logarithmic sensitivity at max minus the logarithmic sensitivity at 640 nm, and lgE 680 represents the difference of the logarithmic sensitivity at max minus the logarithmic sensitivity at 680 nm, and the sensitivities are determined after exposure and processing of the material at a cyan color density which is formed by coupling with developer oxidation product and which is 0.5 above the minimum density, is distinguished by its high sensitivity to light, its good color reproduction both when taking photographs in standard light and in other types of illumination such as artificial light from fluorescent lamps, its good reproduction of colors such as that of delphinium, and its high stability on storage under humid climatic conditions.
