Abstract
An electrophotographic recording element comprising a combination of photoconductive perylene materials that are dispersed in a binder to form layers having excellent photosensitivity and resistance to abrasion. The materials are perylene-3,4,9,10-tetracarboxylic acid imide derivatives that contain a phenethyl radical bonded to a 3,4-dicarboximide nitrogen atom.
