Photographically useful compounds including at least one 1,3-sulfur-oxygen ring system |
摘要 |
There are described heat-developable photosensitive image-recording materials which include a compound having at least one cyclic 1,3-sulfur-oxygen moiety. The compound is stable in the photographic processing composition but capable of undergoing cleavage in the presence of an imagewise distribution of silver ions and/or soluble silver complex made available as a function of development to liberate a reagent in an imagewise distribution corresponding to that of the silver ion and/or the soluble silver complex. The reagent includes a photographically useful group such as a complete dye or dye intermediate.
