| titleOfInvention | PHOTOGRAPHIC PROCESS FOR TRANSFER OF DYES BY DIFFUSION |
| abstract | According to the invention, a photographic material comprising at least one photosensitive silver halide emulsion layer and a non-diffusible chromogenic compound of general formula is exposed according to an image and is developed with a silver halide developer. : (A) n - P - N = N - B (A) 1-n in which A represents an oxidizable organic support residue which contains a group conferring resistance to diffusion and which can be attached via an X bond bridge, from which support remains, either in oxidized or non-oxidized form, a portion is released together with the group imparting resistance to diffusion under alkaline photographic developing conditions, a dye diffusible azo being released simultaneously according to the image and corresponding to the general formula PN = NB in which P represents a monocyclic carbocyclic aromatic group and B represents a bicyclic carbocyclic aromatic group which carries a sulfonamide group in the para position relative to the azo group; and n is 0 or 1; a diffusible dye being released from the non-diffusible chromogenic compound by alkaline development and transferred to an image receiving layer. |
