Definitions

  • the object of the present invention is therefore to propose a method for the electrochemical roughening of aluminum, which is carried out with alternating current and leads to such a uniform roughening structure that the aluminum can be used as a printing plate carrier.
  • a modification can also be applied which causes surface abrasion from the roughened surface, as described, for example, in DE-OS 30 09 103.
  • a modifying intermediate treatment can, among other things, enable the build-up of abrasion-resistant oxide layers and a lower tendency to tone during later printing.
  • Suitable layers also include the electrophotographic layers, ie those which contain an inorganic or organic photoconductor. In addition to the light-sensitive substances, these layers can of course also other components such.
  • D is a diazonium salt group attached to an aromatic carbon atom of A; n is an integer from 1 to 10; and B is the remainder of a compound free of diazonium groups and capable of condensing with an active carbonyl compound in an acidic medium at at least one position on the molecule.
  • photoconductive layers such as z. B. in DE-PS 11 17 391, 15 22 497, 15 72 312, 23 22 046 and 23 22 047 described, are applied to the support materials, whereby highly light-sensitive, electrophotographic layers are formed.
