    Abstract: An electrophotographic recording medium which consists essentially of an electrically conductive base and a photosemiconductive double layer which comprises a first layer containing charge carrier-producing dyes, and a second layer containing one or more compounds which are charge carrier-transporting when exposed to light, wherein the charge carrier-producing dyes are dark in color, possess substantially panchromatic absorption characteristics, and are of the general formula where R1 is propyl, 1-hydroxypropyl, 1-methoxypropyl or 1-phenylethyl, Z is p-phenylazoanilino, phenylthio or anilino, and n is 0-6, and a process for the production of this electrophotographic recording medium.

    Abstract: Halogen-substd. anthraquinones are obtd. by the gas phase oxidn. of diphenylmethane cpds. of formula (I):- (where R1-3 are each H or an aliphatic gp; X aY are each halogen, or the Y gps. and one X gp. may be H) in the presence of a catalyst contg. TiO2 and/or ZrO2 and V2O5 in a wt. ratio of 0.004-0.75 pt. V2O5 based on 1 pt. TiO2 and/or ZrO2. The prods. are useful as raw materials esp. for the prepn. of substd. anthraquinones. The hitherto difficulty obtainable 1-chloroanthraquinone may now be obtained from mono-, di- and polyhaloanthraquinones. The aminoanthraquinones which are also obtainable, are useful in the prepn. of vat dyes and light fast lacquer pigments. In an example, mixt. of 5- and 6-chloro-2-methyldiphenylmethane was oxidise to give a mixt. of 1- and 2-chloroanthraquinone in a 1:7 ratio.
