ABSTRACT:
A color-forming sulfonamidodiphenylamine dye precursor has sulfonamido groups in the ortho position and para position in relation to the --NH-- moiety of the sulfonamidodiphenylamine and, in oxidized form, intramolecularly reacts to produce a sulfonamido-substituted phenazine dye. Such color-forming sulfonamidodiphenylamine dye precursors are useful to produce a dye image by cross-oxidation in an imaging material.
