摘要:
A negatively developing color photographic silver halide material containing at least two blue-sensitive, yellow-coupling silver halide emulsion layers, at least two green-sensitive, magenta-coupling silver halide emulsion layers, at least two red-sensitive, cyan-coupling silver halide emulsion layers and a yellow filter layer on a transparent support, the layers of the same spectral sensitivity having different photographic sensitivities and the blue-sensitive layers being arranged further from the support than the yellow filter layer and the green-sensitive and red-sensitive layers being arranged nearer the support than the yellow filter layer, is distinguished by improved development kinetics if at least one of the green-sensitive layers of highest sensitivity and the red-sensitive layers of highest sensitivity contains a crown ether.
