PURPOSE: To provide a m-phenylenediamine derivative having excellent charge transfer capability and light stability and suitable as a charge transfer material for electrophotographic sensitive material having high sensitivity and excellent durability and usable in electrostatic copier, laser beam printer, etc.
CONSTITUTION: The m-phenylenediamine derivative of formula I [R1 and R2 are H, (substituted)alkyl or alkoxyl, e.g. the compound of formula II. The compound can be produced by reacting a compound of formula III with a compound of formula IV (X is halogen) in the presence of a copper catalyst and a basic substance and reacting the obtained compound of formula V with a compound of formula VI in the presence of a copper catalyst and a basic substance. The amino group of the compound of formula III is preferably acetylated beforehand in the production of the compound of formula V. The compound has high charge transfer capability and excellent optical activity and, accordingly, an electrophotographic sensitive material having high sensitivity and excellent durability can be produced by forming a photosensitive layer containing the compound as a charge transfer material on an electrically conductive substrate.
