Latest Patents
Among his latest patents, one focuses on dye precursors and their use in photographic materials and processes. This invention involves a diphenylamine compound that serves as a precursor for a phenazine dye. The compound features a sulfonyldiamido group in an ortho position to the amine, which can release a sulfonylamine fragment upon oxidation. This process allows the diphenylamine compound to intramolecularly cyclize into a phenazine dye. The released sulfonylamine fragment can thermally release ammonia or an amine, which is beneficial for imaging materials responsive to these substances. Additionally, the diphenylamine compound acts as a silver halide developing agent. Another significant patent involves a color-forming sulfonamidodiphenylamine dye precursor, which has sulfonamido groups positioned in relation to the --NH-- moiety. This precursor can produce a sulfonamido-substituted phenazine dye through intramolecular reactions, making it useful for creating dye images in imaging materials.
