Preparation of cathode-ray tube fluorescent screen

Abstract

Abstract PURPOSE: To improve the brightness of a fluorescent screen, by easily forming a metallic film with excellent reflecting efficiency by dividing an acrylate resin film applied on an inner surface of a face plate into the two layers to a low hardness layer and a high hardness layer. CONSTITUTION: Phosphor particles 1 are photosensitive resin 2, which main component is polyvinyl alcohol, are fixedly sticked to a face plate 3, and constitute phosphor dotted or stripe groups. The first acrylate resin film 4, which is formed on the particles 1 and which Tukon hardness becomes not more than 1, and the second acrylate resin film 5, which Tukon hardness becomes no less than 10, are each made up by using an aqueous emulsion of an acrylate salt copolymer. Such constitution easily form a metallic film 6 with excellent reflection efficiency, can build up a fluorescent screen of a cathode-ray tube that can improve brightness.
