Abstract
A description is given of a method of metallizing an electrically insulating plate, for example, of glass having a large number of holes. Said holes are internally provided with a metal layer and the plate is provided with metal tracks. The metal used is mainly aluminum. The aluminum is coated with a thin protective layer of chromium, cobalt, nickel, zirconium or titanium. Said protective layer makes it possible to use a photosensitve, cataphoretic lacquer for providing the metal layer with a structure. The method can very suitably be used for the manufacture of selection plates for thin electron displays.
