ABSTRACT:
There are disclosed color-providing compounds comprising two or more cyclic 1,3 sulfur-nitrogen groups and two or more color-providing moieties, i.e., complete dyes or dye intermediates, capable of releasing the color-forming moieties upon cleavage in the presence of silver ions or a soluble silver complex. The color-providing compounds are useful as image-forming materials in color photographic processes.
