Patent number: 4411984Abstract: A diphenylamine compound that is a precursor for a phenazine dye comprises, in an ortho position to the amine of the diphenylamine, a sulfonyldiamido group (--NHSO.sub.2 NHR) that is capable of releasing a sulfonylamine fragment upon oxidation. The diphenylamine compound upon oxidation intramolecularly cyclizes to a phenazine dye. The sulfonylamine fragment is capable of thermally releasing ammonia or an amine. The diphenylamine compound and sulfonylamine fragment are useful in imaging such as in photothermography. Ammonia or an amine thermally released from the sulfonylamine fragment enables imaging in imaging materials that are responsive to ammonia or an amine. The diphenylamine compound also generally is a silver halide developing agent.Type: GrantFiled: May 3, 1982Date of Patent: October 25, 1983Assignee: Eastman Kodak CompanyInventor: Rolf S. Gabrielsen
