  • Patent number: 5759420
    Abstract: A process for producing a partially transparent, visually discernible surface pattern with surface elements which diffusely scatter, reflect or diffract light incident on the surface pattern commences with a base foil which may include a carrier foil and a lacquer layer, and also an intermediate layer between these two layers to provide for good adhesion. Before or after application of the microscopically fine relief structures in the lacquer layer, the free surface thereof is covered over its entire area with a reflection layer. A printed image is then printed with an etching agent for the reflective material on the reflection layer in such a way that, at surface portions corresponding to the printed image, the reflection layer is removed and the surface of the lacquer layer is exposed again.
