    摘要: 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.

    摘要: 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.

    摘要: There are described novel pyrazole compounds represented by the formula ##STR1## wherein Y is a silver halide developing substituent or a precursor thereof; R is --OH, --NH.sub.2 or --NHSO.sub.2 --R.sub.1 ; R.sub.1 is alkyl having from 1 to 6 carbon atoms or phenyl; and m and n are the same or different and each is an integer of from 1 to 6. The pyrazole compounds are useful as intermediates in the preparation of azo and azomethine dye developers or as silver halide developing agents.
