Abstract

NEW MATERIAL:A disazo compound shown by the formulaI.
USE: Pigment for producing electric charge of a laminate type photosensitive material for high-speed copying machine. Having high sensitivity.
PROCESS: 2,7-Diamino-9-fluorenone shown by the formula II is diazotized in a dilute inorganic acid to give a tetrazonium salt shown by the formula III (X is aninoic functional group) (e.g., 9-fluorenone-2,7-bisdiazonium bistetrafluoroborate, etc.). This compound is then reacted with 2-hydroxy-3-(2-fluorophenylcarbamoyl) natphthalene shown by the formula IV, to give a compound shown by the formulaI.
