There are disclosed dye-providing compounds comprising color coupler dyes substituted on the phenylene diamine portion with one or two cyclic 1,3-sulfur-nitrogen groups. The dye-providing compounds are capable of releasing the coupler dye upon cleavage in the presence of silver ions or a soluble silver complex. The dye-providing compounds are useful as image-forming materials in color thermographic, photothermographic and other photographic processes.
