See full text

A method for producing a multilayer body, with the steps of:

    a) providing a substrate film with a replication layer;b) molding a surface relief appearing to the observer in the form of a three-dimensional free-form surface, which is formed in particular by structures with a lens-like design generating a magnifying, demagnifying or distorting effect, into a surface of the replication layer;c) applying a first metal layer to the surface of the replication layer forming the surface relief;d) wet-chemically applying an at least partially transparent spacer layer to the metal layer;e) applying a second metal layer to the spacer layer.
