Abstract
In a color photographic process wherein a color photographic material having at least one silver halide emulsion layer is developed after imagewise exposure in a color developer containing a primary aromatic amine color developing agent to form dye images, the intensification effect of the color images formed is increased with less formation of fog by employing silver iodobromide containing at least about 2 mole percent silver iodide as the silver halide of the silver halide emulsion and developing the silver halide emulsion layer in the presence of a cobalt (III) complex incorporated in the photographic material or a processing solution at temperatures of about 50.degree. C or higher.
