摘要： A process is described for the formation of an undercoat which is in turn useful in forming a CRT metal back layer. According to the process, a pretreatment composition is coated on a glass panel having a fluorescent layer overlaid thereon, so that a water film is formed. The pretreatment composition is composed of 2-20 wt. % of an alkyl monoalcohol having a C.sub.1-3 alkyl group, 0.05-1 wt. % of a water-soluble, high molecular compound and 79-97.95 wt. % of water. An undercoating composition is then coated on the water film by a wet-on-wet coating method, whereby a coating layer is formed. The undercoating composition is composed of 1-7 parts by weight of an acrylic resin, which has been obtained by polymerizing 90-100 wt. % of an alkyl methacrylate having a C.sub.1-4 alkyl group other than tertbutyl methacrylate and 0-10 wt. % of an ethylenically unsaturated monomer copolymerizable therewith, and 99-93 parts by weight of a solvent containing at least 80 wt. % of toluene. The sum of the acrylic resin and the solvent is 100 parts by weight. The water film and the coating layer are dried to form the undercoat.

摘要： A method for manufacturing a phosphor screen used in a color CRT takes the steps of multilayering a red phosphor layer, a green phosphor layer, a blue phosphor layer, and a non-luminescent layer being laid between the adjacent color phosphor layer, cutting the multilayered block into filmy pieces toward the thickness, adhering or pressurizing the filmy cut pieces on a glass plate for front panel of the color CRT, and burning the cut pieces. This method makes it possible to efficiently manufacture a high-definition and high-resolution color phosphor screen and form fine RGB stripes. This method, thus, may apply to a small-sized CRT about which the realization of the high-definition and high-resolution color phosphor screen has been difficult.
