Production of partially metallised grating structures

摘要

The method involves moulding microscopically fine relief structures (6) into a base sheet whose structured layer of lacquer (1) is then coated with a reflective layer (3). An etchant is applied to the reflective layer in a pre-set printing format consisting of part surfaces. The reflective layer is then removed by the etchant from the part surfaces, and the surface of the lacquered layer exposed. To form the plastics laminate, the lacquered layer in the part surfaces, and the remaining surfaces of the reflective layer are coated with at least one transparent protective layer (19). Transparent adhesive bridges (21) result from the direct connection between the lacquered layer and the protective layer, in the part surfaces.
