Abstract
In electrophotographic copying processes use is made of a reproduction element comprising on a conductive support a photoconductive layer containing dispersed in a binder a bisazo naphthol compound having a certain structure of substituents whereby the reproduction element exhibits relatively high light-sensitivity and is repeatedly exposable and developable imagewise so as to be useful for indirect electrophotographic copying. Special binder compositions enhance the light-sensitivity of the element and special layer constructions are provided to suit it for certain uses.
