    摘要： An electrophotographic recording material consists of (A) an electrically conductive base and (B) a photoconductor layer containing (a) a polymeric binder, which either is itself capable of transporting charge carriers or contains charge carrier-transporting compounds, and (b) sensitizers, with or without (c) other additives conventionally used in photoconductor layers.Compounds (c), used according to the invention are compounds of the formula ##STR1## where R.sup.1 is H or C.sub.1 -C.sub.8 -alkyl, R.sup.2 is C.sub.1 -C.sub.8 -alkyl, Hal is Cl or Br and n is an integer from 2 to 6. The compounds (IV) are present as a molecular-disperse solution in the polymer matrix.The recording materials are highly photosensitive over the entire visible range of light, and are therefore very useful for reprographic purposes.
