Abstract: There are described image-recording materials which include an image dye-providing compound comprising a novel naphthol azo cyan dye having a 3-aminobenzoisothiazole moiety. The image dye-providing compound includes a diffusion control moiety such as a hydroquinonyl developer group, a precursor thereof or a thiazolidine moiety and, may be diffusible or nondiffusible as a function of the diffusion control moiety. Image-recording materials according to the invention including those which contain high potential developers such as aminoreductone allow sufficient cyan chromophore to diffuse to the image-receiving layer to provide an acceptable photograph and result in no appreciable reduction of the 3-aminobenzoisothiazole moiety of the novel naphthol azo cyan dye.
