Abstract: This invention relates to photographic processes for producing color images by reacting (a) a dye intermediate containing a carbonyl group and selected from an aldehyde and a ketone with (b) a color-forming reagent to form a complete dye wherein an imagewise distribution of at least one of said dye intermediate and said color-forming reagent is formed as a function of developing an exposed silver halide layer followed by reacting the color-forming reagent with the carbonyl group of the dye intermediate to form a corresponding imagewise distribution of a complete dye. In a preferred embodiment, a sulfur-nitrogen compound capable of undergoing cleavage in the presence of silver ions and/or soluble silver complex made available as a function of development is used to release one or both of the dye-forming reagents in an imagewise distribution corresponding to said silver ions and/or said complex.
