Definitions

a recording material for the production of printing for men or printed circuits can be provided, which is highly photosensitive in a wide spectral range and which proves to be insensitive to pre-exposure.
the arrangement of the photoconductive insulating layer in the form of a monodisperse layer also enables a simpler method of production.
the electrophotographic recording material according to the invention can contain, as conventional additives, leveling agents and plasticizers in the photoconductive layer and / or adhesion promoters between the support and the photoconductive layer.
the layer thickness of the photoconductor layer is not critical and is generally in the range of 2-10 pm, but depending on the application, it can exceed or, if necessary, fall below these limits.
Example 1 For comparison and to measure the pre-exposure sensitivity, the layer on layer support 1 was measured several times with the comparison material according to Example 1 under the same conditions with negative charging in accordance with the information in Example 1:
the dispersion mixture was then layered on a 100 ⁇ m thick, wire-brushed aluminum foil in a thickness of 4 to 5 ⁇ m (dried) and the photosensitivity of this dispersion layer was determined.
