Abstract

PURPOSE: To prevent separation of a filter material from a filter-covered fluorescent substance used for the fluorescent screen of a color picture tube and to enhance the luminous efficiency of the substance by coating the outside of the filter with a polyvinyl acetal type resin.
CONSTITUTION: The surface of a fluorescent substance, e.g. silver-activated zinc sulfide one is covered with a filter material of silicate, pref. calcium silicate and the outside of the filter is further coated with a polyvinyl acetal type resin, e.g. polyvinyl formal resin or polyvinyl butyral resin to give a filter-covered fluorescent substance forming a color television fluorescent screen. The amt. of the resin coated is pref. 0.05W3% to the fluorescent substance. The resin is insol. in water, suitable for use as a coating material, and also suitable for use as a binder for a fluorescent substance dispersion. After forming a fluorescent screen, the resin can be removed easily by baking at 400W500°C and hence it does not deteriorate the screen.
