    Abstract: Relief plates crosslinked by photopolymerization are produced by exposing layers which are crosslinkable by photopolymerization imagewise to actinic light and washing out the noncrosslinked parts of the layers with a developer, by a process in which the developer used contains, as an essential component, a branched or straight-chain, monoolefinically, diolefinically or triolefinically unsaturated acryclic or saturated or monoolefinically, diolefinically or triolefinically unsaturated cyclic aliphatic hydrocarbon, alcohol or ketone of 8 to 15 carbon atoms.

    Abstract: 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 where R1 is H or C1-C8-alkyl, R2 is C1-C8-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.

    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.
