Abstract
Naphthalenetetracarboxylic acid diimide derivatives represented by the following general formula, ##STR1## wherein R is a hydrogen atom, an alkyl group, an alkoxyl group or a halogen atom, R1 and R2 are different from each other and may be a substituted or unsubstituted alkyl group, alkoxyl group or an aryl group, respectively, and R3 is a hydrogen atom, a substituted or unsubstituted alkyl group, an alkoxyl group or an aryl group. The derivatives exhibit excellent solubility in an organic solvent, excellent compatibility with a resin binder and excellent photosensitivity, and are very useful as an electron transporting agent for the electrophotosensitive material.
