Title: Electrophotographic reproduction element of an aniline compound electron acceptor

Abstract: Reproduction elements coated with organic photoconductors are made with improved and/or more widely selectable electrophotographic properties by employing in the photoconductive coating a donor-acceptor complex composed of a known organic electron donor having photo- or semiconductor properties, e.g. a poly-N-vinylcarbazole or polyvinylpyrene, and a N-(fluoren-9-ylidene)-aniline compound as an activating electron acceptor. Especially effective as the electron acceptor are certain new compounds, namely, p- and m-nitro-N-(2,4,7-trinitrofluoren-9-ylidene)-aniline and p-methylsulfonyl-N-(2,4,7-trinitrofluoren-9-ylidene)-aniline.
