ABSTRACT:
There are disclosed compounds comprising at least one cyclic 1,3-sulfur-nitrogen substituted color-providing material and at least one ballast group which are linked to each other through a triazine group. The compounds are capable of releasing the color-providing material 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 thermographic, photothermographic and other photographic processes.
