Abstract:
1. A method of making a vapor-deposited metallized film, comprising the steps of: applying a vacuum in a pre-treatment step of the film substrate by cleaning the film surface by means of a plasma treatment with Argon, under vacuum, and simultaneously initiating the film with target atoms forming an initial layer; forming a structured layer by vapor-depositing one or more of a material selected from the group consisting of metal, a metal composition and an alloy on a surface of the pretreated film, or applying an insulator by a method selected from the group consisting of by printing or lacquering to form the structured layer; and thereafter positively imprinting the film with an etch resist in correspondence with a desired pattern; carrying out an etching method for removing the areas not imprinted with the etch resist, so that a structured layer remains on the film in the desired shape and thickness; stripping the etch resist, and reinforcing a non-imprinted surface by negative imprinting with a galvanic resist which is subsequently stripped away and the desired pattern finished through differential etching.
