Definitions

  • the invention relates to a method for producing a sliding layer on the surface of the aluminum layer of a recording medium by the action of one or more fatty acids.
  • EP-A-35105 which is considered prior art under Art. 54 (3) and (4) EPC, a method for at least partially converting an aluminum layer on a recording medium has already been proposed, during which and / or after the Precipitation of the aluminum layer in a vacuum, the aluminum is at least partially reacted with the vapor of a fatty acid, the degree of conversion being set by the partial pressure of the fatty acid.
  • the recording medium is coated on the front with one and on the back with one or more nitro lacquer layers, in that the last lacquer layer on the back is 0.1 to 2% by weight, based on the wet lacquer or more fatty acids are admixed, that the front side of the recording medium is coated with aluminum in a vacuum and that the coated recording medium is wound up in a roll in the vacuum chamber and is exposed in this form to a longer aging period.
  • the procedure is preferably such that 0.1 to 2 percent by weight, based on the wet paint, oleic acid or a mixture of various fatty acids, such as. B. admixed tall oil.
  • the procedure is as follows: The paper is coated in a conventional manner on the front with a nitro varnish, which is colored and pigmented as required. In addition, one or more layers of a nitro lacquer are then applied to the back, 0.1 to about 2.0% by weight, based on the wet lacquer, of a fatty acid or a mixture of fatty acids being added to the last layer.
  • this lacquer layer is applied as the last layer in the overall process. Since in many cases such recording media coated with aluminum are already provided with a back coating in order to achieve an absolute opacity of the labeled paper, a suppression of the tendency to curl, etc., such a measure can be carried out almost cost-neutral.
  • the Record carrier material is by no means immediately usable immediately after coating the record carrier material with aluminum due to the lacquer layer underneath the aluminum layer, that the rolls so wound for curing this lacquer layer anyway require a longer period of time, which preferably extends over one or more months.
  • the fatty acids contained in the back coating e.g. B. oleic acid or mixtures of fatty acids, e.g. B. tall oil simultaneously exert their effect on the aluminum layer.
