Abstract:
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), wherein the spectral sensitivity distribution of BG-1 is characterized in that605&lE;&lgr;max&lE;630 nm, 0.1&lE;&Dgr;lgE640&lE;0.6 and 1.8&lE;&Dgr;lgE680, wherein &lgr;max represents the wavelength at which the maximum sensitivity occurs, &Dgr;lgE640 represents the difference of the logarithmic sensitivity at &lgr;max minus the logarithmic sensitivity at 640 nm, and &Dgr;lgE680 represents the difference of the logarithmic sensitivity at &lgr;max minus the logarithmic sensitivity at 680 nm, and the sensitivities are determined after exposure and processing of the material at a cyan colour density which is formed by coupling with developer oxidation product and which is 0.5 above the minimum density.
