Abstract: In order to prepare acrylate and/or methacrylate polymers containing lateral carbazolyl groups, polymers of acrylyl chloride and/or methacrylyl chloride are reacted in solution in a polymer-analogous reaction with alcoholates of N-( omega -hydroxyalkyl)carbazoles. The poly(meth)acrylates prepared in this way have good photoconductor properties and are advantageously suitable for use in electrophotographic recording elements.

Abstract: The novel electro-photographically produced offset printing plate comprises an electrically conductive dimensionally stable substrate (A), at least one photoconductive layer (B) and a printing surface (C) composed of hydrophilic, water-bearing, unprinted tonered areas (c1) and oleophilic, colour-bearing printing untonered areas (c2). The novel offset printing plate can be made by the prior art manner making use of hydrophilic toner or toner which can be easily hydrophilised chemically by conversion with suitable reagents, thermo-chemically by heating and/or photo or radio-chemically by irradiation with electromagnetic or particle radiation.

Abstract: The invention relates to photoconductors having liquid-crystalline properties made from low-molecular-weight or polymeric organic compounds, where the photoconduction in the discotic phase is greater than in the non-liquid-crystalline phases, and to a process for increasing the photoconductivity by molecular ordering in photoconductors.
