Abstract: The present invention relates to a method for manufacturing a metallized luminescent screen for a CRT. At least one phosphor layer is deposited (10) on an inner surface of a faceplate panel to form the luminescent screen. The panel containing the screen is then preheated (12) to a temperature equal to, or in excess of, a minimum film-forming temperature and prewetted (14) by applying water to the screen. An aqueous filming emulsion containing a copolymer of acrylates and methacrylates with an average molecular weight of from 250,000 to 500,000 is applied (16) to the prewetted screen and dried (18) to form a film layer. Next, a layer of aluminum is deposited (20) onto the film layer, and the panel, bearing the metallized screen, is sealed to a funnel by heating the panel and the funnel through a sealing cycle. The sealing cycle(22) has a first rate of temperature increase to a first temperature and a second rate of temperature increase, less than the first rate, to a second temperature.

Abstract: A process of manufacturing a cathode-ray tube (21) having a faceplate panel (27) with an exterior surface (39) having thereon an anti-glare, anti-static, dark coating (37) is described. The process is characterized by the steps of (a) forming a substantially homogeneous initial carbon dispersion containing substantially equal parts, by weight, of carbon particles and an organic vehicle; and (b) combining a sufficient quantity of the homogeneous initial carbon dispersion with an aqueous solution of lithium polysilicate to form a final dispersion suitable for application to the faceplate of the CRT.

Abstract: According to the present invention, an anti-glare, anti-static coating (37) applied to a reflective-transmissive surface (39) comprises a thiophene-based, electroconductive polymer and a siliceous material. A composition for reducing glare and for providing an anti-static property when applied to the reflective-transmissive surface (39) also is disclosed, as is a method of applying the coating (37) to an exterior surface (39) of a faceplate panel (27) of a CRT (21).

Abstract: Procedure for the continuous fractionation of polymers dissolved in a solvent, which includes at least one complete cycle of the following operations:a. precipitation of a first fraction of polymer inside a first reaction vessel containing the solution;b. transferring the remaining solution into a second reaction vessel and collecting the above first fraction of polymer precipitated in the above first reaction vessel;c. precipitation of a second fraction of polymer inside the second reaction vessel; andd. recycling the remaining solution in the first reaction vessel and collecting the above second fraction of polymer precipitated in the above second reaction vessel.
