Title:
COLOR DEVELOPING PIGMENT PRECURSOR COMPOUND AND CORRESPONDING PHENAZINE PIGMENT
Document Type and Number:
Japanese Patent JPS5865429
Kind Code:
A
Abstract:
A color-forming para sulfonamidodiphenylamine dye precursor has one or two sulfonamido groups in positions ortho to the amine -NH- moiety separating the two phenyl rings of the para sulfonamidodiphenylamine and, in oxidized form, intramolecularly reacts to produce a sulfonamido-substituted phenazine dye. Such color-forming para sulfonamidodiphenylamine dye precursors are useful to produce a dye image by cross-oxidation in an imaging material.
