ABSTRACT:
A method for electrophotographically forming a Braun tube's fluorescent layer coats conductive and photoconductive layers on the internal surface of a Braun tube's panel. The photoconductive layer is formed of a water soluble photoconductive liquid including a water soluble binder, allowing a part of the photoconductive layer to be selectively exposed to a visible ray. The photoresist of the above photoconductive liquid is substituted with dye, which can be processed through general exposure and solvent, allowing the fluorescent layer to be formed on a Braun tube under the same conditions as a typical Braun tube production process without darkroom processing.
