Class Information
Number: 430/223
Name: Radiation imagery chemistry: process, composition, or product thereof > Transfer procedure between image and image layer, image receiving layers, or element containing an image receiving layer or an ingredient for forming an image receiving layer > Diffusion transfer process, element, or identified image receiving layers therefor > Element or identified image receiving layers for dye image formation > Element containing silver salt sensitizer or either element or image receiving layer for use therewith > Identified dye image forming compound other than colorless color developer or dye mordant containing or identified organic solvent for an incorporated ingredient > Redox cleavable dye or dye precursor releaser
Description: Subject matter wherein the dye image forming compound comprises a dye or dye precursor moiety and at lest one other moiety and which upon oxidation or reduction in a medium cleaves to separate the dye or dye precursor moiety from the other moiety and wherein the separated dye or dye precursor moiety has a degree of diffusibility in the element during processing substantially different from the degree of diffusibility of the uncleaved dye image forming compound in the element during processing.
