Ballasted dye compounds with linkages containing three aromatic nuclei for use in a dye diffusion transfer process and element |
摘要 |
Photographic silver halide emulsion material for use in a dye diffusion transfer process incorporating a non-diffusing compound capable of releasing a diffusible mono-azo dye or dye precursor thereof from a carrier moiety, said compound corresponding to the following general formula (I): (I) CAR-L-G-D wherein: CAR represents a ballasted carrier moiety, L represents a chemical group cleavable or releasable from the carrier moiety as a function of a redox-reaction or argentolytic reaction taking place in the development of a silver halide emulsion layer under alkaline conditions, G represents a bivalent organic group incorporating at least three aromatic nuclei, selected from the group consisting of homocyclic or heterocyclic aromatic nuclei, with the provisions that L is linked to one end nucleus and that D is linked to the other end nucleus of said bivalent organic group; said linking being by means of a direct bond or by means of a bivalent mono- or polyatomic group, and D is an azo dye part linked to said other end aromatic nucleus of G.
