摘要:
An electrophotographic recording material is described that comprises an electrically conducting base layer and a photoconductive system deposited thereon, which system comprises an optional insulating intermediate layer, a layer containing a charge-generating compound, and a layer containing a charge-transporting compound mixed with binders, along with any sensitizers, acceptors and usual additives. The photoconductive system contains, as acceptor additive, one or more monomeric or polymeric compounds that have electron-attracting substitutents (halogen, cyano, nitro groups) and that are selected from the group consisting of anthracene, acridine, the anhydrides of phthalic acid, maleic acid, pyromellitic acid, benzophenonetetracarboxylic acid, and the polymers of vinyl chloride, vinylidine chloride and nitrocellulose, in a quantity of 0.2 to 10% by weight based on total coating weight. After erasure of the latent electrostatic image, the recording material has a low residual charge, even when operated cyclically. Background imaging is thereby avoided.
