    摘要: Useful non-diffusible dye-giving compounds for the photographic dye diffusion transfer process are dye sulfonamides derived from enolamines or endiamines or tautomers thereof. The dye-giving compounds are oxidized by developer oxidation products and subsequently split under the conditions of alkaline development to release diffusible dyes. The compounds are of the following formula ##STR1## in which X is a dye moiety and R.sub.1, R.sub.2 and R.sub.3 have meanings given hereinafter.

    摘要: 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 diffusing dyes, which are transferred to an image-receiving layer. The dye-giving compounds have the formulaY--NH--Ar--NH--SO.sub.2 --Xar represents an arylene radical such that the group Y--NH-- is attached to the group --NH--SO.sub.2 --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 --SO.sub.2 R radical; andR represents an alkyl, aryl or heterocyclic group and can constitute part of a second dye moiety.
