ABSTRACT OF THE DISCLOSURE This disclosure depicts methods and structures for applying a very thin layer of electrically conductive, light- reflective metal such as aluminum to the phosphor screen of a cathode ray tube. More particularly, there is disclosed the application of such a metal layer by the transfer of a metal layer formed on a substrate directly to a phosphor layer on the inner surface of a cathode ray tube faceplate. The metal layer is adhered to the phosphor layer by an adhering step which may involve the use of a pressure-sensitive adhesive. In one embodiment disclosed, the substrate is then stripped off; alternatively, the substrate may be removed by dissolution or volatilization. Remaining volatile substances are driven off in a baking operation. Other associated and alternative operations are depicted. -1-
