Abstract (en)
[origin: EP0802267A1] Interference layer contains an aluminium oxide layer and a partially transparent layer deposited on it. The novelty is that the aluminium oxide layer is an anodically produced, transparent and pore-free barrier layer with a thickness of according to the required surface colouring of the interference layer. The thickness d is 20-900 nm, and the partially transparent layer has a wavelength dependent transmission t( lambda )) which is 0.1-1. Production of the interference layer is also claimed.
