Abstract

Electrophotographic compsn. for use in copying materials consists of (I) a pigment of formula (I) or (II), and (II) an electrically insulating or cooperating binder. (where Me is a metal atom; and R1-R4 are each the atoms required for an opt. substd. carbocyclic or heterocyclic aromatic ring system). The compsn. has a low pemanent memory, good light sensitivity, good mechanical props, and easily produces smooth layers.
