Abstract:
A method for manufacturing a metallized luminescent screen, for a cathode-ray tube including 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 said film with an aqueous formulation of a styrene-acrylic copolymer; drying the copolymer coating; depositing a metallic layer onto said copolymer coating; and removing by decomposition organic materials contained in the luminescent screen, the film and the copolymer coating, by baking the panel, wherein the formulation for coating the film contains polymer hollow spheres and the spheres burst at a lower temperature than the decomposition temperature of the hollow spheres.
