摘要: Electrophotographic elements utilizing a layer containing an organic photoconductor, e.g. poly-N-vinylcarbazole, are provided with enhanced light-sensitivity together the other properties required for electrostatic photocopying by incorporating in said as electron acceptor dibenzothiophene oxide, or dioxide, that forms donoracceptor complex photoconductor. A preferred is 1,3,7-trinitro-dibenzothiophene-5,5-dioxide, new compound.
