Abstract: A color cathode ray tube having an improved screen and manufacturing method thereof including a black matrix and a phosphor layer formed on the inner surface of a panel and a metal back covering the tops of the black matrix and the phosphor layer. The metal back is in direct contact with the black matrix and is spaced from the phosphor layer. In the manufacturing method, a film overlapping the black matrix layer is partially removed so as to leave the film above the phosphor layer. This allows the metal back to be applied directly to the black matrix layer and thereby prevents the desquamation of the metal back.

Abstract: A color cathode ray tube with reduced desquamation includes a panel on which spaced-apart phosphor elements and a black matrix, filling the spaces between and contacting the phosphor elements, are disposed. A metal back covers the phosphor layer and the black matrix and is in direct contact with the black matrix and is spaced from and does not contact the phosphor elements. The direct contact with substantially all the black matrix and the complete separation from the phosphor elements improves the adhesion of the metal back while increasing luminance and reducing desquamation of the metal back.

Abstract: A method for manufacturing a cathode ray tube is provided which comprises (a) spraying on the inner surface of a phosphor layer of a phosphor coated panel, an organic composition for forming a heat labile film, the organic composition being free of flammable or explosive organic solvents and including an initiator capable of forming a radical or cation when exposed to ultraviolet or electron rays and at least one resin containing at least one group consisting of acrylate, vinyl and diazo functional groups to form a heat labile film thereon; (b) exposing the heat labile film to ultraviolet or electron rays to from a hardened film layer; (c) forming an aluminum layer on a surface of the hardened film layer to form a screen; (d) sealing with heat the panel and a funnel to form a bulb with a mount including an electron gun and a stem, wherein the step of sealing to form a bulb decomposes the hardened film layer.
