Abstract (en)
[origin: US4297438A] Color images are obtained by chromogenic development of a colorphotographic material comprising several differently spectrally sensitized silver halide emulsions and color couplers associated thereto, a hydrophobic cyan coupler being incorporated by means of a hydrophobic coupler solvent and a hydrophobic yellow coupler being incorporated without a coupler solvent, when a color developing composition is used comprising a hydrophilic and a hydrophobic color developer compound. The color images have good stability of the cyan partial image to tropical conditions and good lightfastness of the yellow partial image.
