ABSTRACT:
In a method of manufacturing a color cathode ray tube utilizing an external surface exposure process, a fluorescent slurry to be applied to a panel contains a photosensitive resin composition composed of an aqueous emulsion of polyvinyl compound resin containing a saponified polyvinyl acetate with an addition-condensed photosensitive group as a protective colloid and an aqueous solution of a saponified polyvinyl acetate with an addition-condensed photosensitive group. Accordingly, a resistance of a fluorescent layer formed on the panel against an aqueous solution of hydrogen peroxide is improved, and an anti-fogging performance of the fluorescent layer is also improved.
