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.
