PHOTOGRAPHIC DYE DIFFUSION TRANSFER PROCESS

摘要

() Useful non-dissusible die-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 in which X is a dye moiety and R1, R2 and R3 have meandings given thereinafter.
