Abstract
A multi-layer PVD film stack contains a first layer higher index of refraction metal followed by a second layer semi-transparent lower index of refraction metal. The thickness of the second layer dictates the reflectivity of the second layer material. The second layer not only increases the reflectivity of the first layer, but it also decreases the reflectivity lost when the PVD film is topcoat lacquered. However, lacquering decreases the reflectivity of the higher index first layer (generally n value >1.9 at 632 nm). Using a higher refractive index metal as an opaque first layer followed by a semi-transparent second layer of a lower refractive index metal minimizes the darkening of the metal(s) after lacquer topcoat due to the lower refractive index of the second layer, which is in contact with the lacquer.
