Benz¬g quinoxalin-5,10-dione (=naphthoquinone) derivatives, their preparation and their use in electrophotographic material

摘要

The present invention provides a novel naphthoquinone derivative preferred as an electron transporting agent and an electrophotographic photosensitive material of high sensitivity which contains a novel naphthoquinone derivative having a general formula (1) wherein R<1> represents a hydrogen atom, an alkyl group which may have a substituent, or an aryl group which may contain a substituent, and R<2> represents a hydrogen atom, an alkyl group which may have a substituent, a halogenated alkyl group, an aldehyde, a nitro group or a group (i). The derivative is contained in a photosensitive layer of an electrophotographic photosensitive material as an electron transporting agent.
