Abstract

Electrophotographic recording materials which comprise an electrically conductive base, charge carrier-producing compounds (sensitizers), and charge carrier-transporting compounds, possess high photoconductivity and low conductivity in the dark, and contain, as charge carrier-transporting compounds, 2-substituted benzotriazoles of the formula ##STR1## are used for reprographic purposes and for the production of electrophotographic printing plates, in particular offset printing plates.
