摘要:
A photosensitive recording medium has a structure wherein, on a light-transmitting base material, a photosensitive layer containing color image-forming photosensitive microcapsules having as materials encapsulated therein a colorant and a photosensitive material is formed and, on the photosensitive layer, an image-receiving layer is formed. The image-receiving layer has a function to cover up the photosensitive microcapsules in the fresh photosensitive recording method and, upon release of the encapsulated materials from the photosensitive microcapsules, a function to absorb the encapsulated material to form an image. The photosensitive recording medium enables formation of full-color images on the photosensitive recording medium itself, and can achieve a low running cost and also be used even in small-sized image-forming apparatus.

There are described color-providing compounds having at least two cyclic 1,3-sulfur-nitrogen moieties and one complete dye or dye intermediate. The color-providing 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 complete dye or dye intermediate in an imagewise distribution corresponding to that of the silver ion and/or the soluble silver complex. The color-providing compounds are useful as image-forming materials in color photographic, photothermographic, thermographic, and other processes.
