A PHOTOGRAPHIC DYE DIFFUSION TRANSFER PROCESS (Abstract of the Disclosure) In the photographic dye-diffusion transfer process use is made of dye-giving compounds, which are non diffusing in photographic binder layers, and which during development if oxidized imagewise in accordance with the silver halide developed are split owing to the alkali of the developer composition to release diffus- ing dyes, which are transferred to an image-receiving layer. The dye-giving compounds have the formula Y-NH-Ar-NH-SO2-X Ar represents an arylene radical such that the group Y-NH- is attached to the group -NH-SO2-X through a chain of n(n=1,2,3, or 4) vinylene groups which are part of the arylene radical; X represents the radical of a dye or dye precursor; Y represents a -COR or -SO2R radical; and R represents an alkyl, aryl or heterocyclic group. and can constitute part of a second dye moiety.
