Abstract
A method for manufacturing a metallized luminescent screen, for a cathode-ray tube, includes the steps of:depositing at least one phosphor layer on an inner surface of a faceplate of a panel to form said luminescent screen,depositing on said layer a sub-layer consisting of a lacquer,drying said sub-layer to form a film,coating at least partially the internal surface of the faceplate panel with an aqueous solution of a copolymer of acrylic/styrene,drying the copolymer coating,depositing a metallic layer onto said copolymer coating,removing the organic materials contained in the luminescent screen, the film and the copolymer coating, by baking the tube panel.
