摘要：The invention relates to a method for producing a security element whichcomprises a substrate with at least one opening, wherein the opening is closed on oneside with a light-permeable film. The security element according to the invention isapplied to a value document or is part of a value document. If the security element ispart of a value document, the opening is introduced into the substrate of the valuedocument. According to the invention, at least one at least partially light-permeablecoating is applied to the upper side and the lower side of the substrate, preferablyextruded in a single working step. Both the upper and the lower side of the substrate arethus covered with a light-permeable coating which is preferably applied on the entirearea. The light-permeable coating therefore is not only present within the opening insidethe substrate or overlaps said opening only by a few millimeters, but covers alsopreferably a large part and particularly the entire surface of the substrate.
