PROCESS FOR FORMING PHOSPHOR SCREENS WITH TREATED PHOSPHORS

摘要

Color Brown tube phosphor screen was formed by dopping a photosensitive compn. exhibiting spot deviation by light exposure and being consisted of arom. diazonium or its salt as photosensitive compn. on the surface of base substance, and making thin layer and contacting phosphor particles with thin layer after light exposure so as to accept the phosphor particles on the thin layer according to its powder accepting capability. The surface of used phosphor was coated with one cf Zn(OH)2, Zn3(PO4)2 and AlPO4.
