Abstract
Method of forming a photographic color image which comprises imagewise exposing a photographic silver halide color material and processing it with an alkaline processing solution in the presence of a sulphonhydrazide color developing agent and a 3-pyridinol color coupler optionally containing in the 2-position a ballasting group of such size and configuration as to render the coupler non-diffusible in photographic materials thus forming a dye image by reaction of the oxidized color developing agent and the color coupler.
Claims9
A color photographic material comprising at least two color-forming units sensitive to different regions of the spectrum each comprising a silver halide emulsion layer wherein the material contains in at least one said silver halide emulsion layer, a ballasted sulphonhydrazide color developing agent and a 3-pyridinol photographic color coupler capable of forming a magenta dye upon coupling with the oxidized form of said developing agent, both incorporated therein in droplets of a high boiling solvent.
