Definitions

  • the invention relates to a method for reducing or completely removing traces of grinding or scratching on the surface of a recording medium coated with a thin metallic layer, preferably made of aluminum, by coating the surface with a 'thin, approximately 2 nm to 1000 nm thick layer of a metal soap according to patent ... (patent application P 30 11 591.4).
  • the writing electrodes In the electrographic recording process on a film coated with an aluminum layer or on a paper coated with an aluminum layer and a lacquer layer, the writing electrodes must be in direct electrical contact with the aluminum layer. Almost every recording device is designed for a continuous writing process, ie there is always a relative movement between the writing electrodes and the aluminum-coated recording medium. The electrical contact between the electrodes and the aluminum-coated recording medium must also be ensured during this relative movement, ie the electrodes grind on the aluminum layer, regardless of whether writing is in progress or not. This grinding leaves traces of grinding or scratching in the areas in which the aluminum has not burned out, ie evaporated.
  • metal soap layers of this type can be applied, for example, by immersion, spraying, vapor deposition or sputtering processes or else purely mechanically.
  • the metal soap with about 10-30% by weight of a polyfunctional, aliphatic alcohol before application.
  • the procedure is preferably such that the metal soap is mixed in a mortar or in a mill with about 10-30% by weight of the aliphatic alcohol to form a homogeneous, smooth mass.
  • both saturated and mixtures of saturated and unsaturated metal soaps can be used.
  • sodium or potassium soaps are also suitable here, such as. B. their stearates and palmitates.
