More Information
Summary:A colorphotographic material with at least one silver halide emulsion layer which contains in dispersed form a color coupler substituted with a dicyclopentyl phenoxy group. This substitution lowers the melting point of the coupler and increases its solubility in solvents used to incorporate the couplers in photographic layers. Layers with these couplers are accordingly more stable.
