Abstract
1,086,374. Luminescent screens. SYLVANIA ELECTRIC PRODUCTS Inc. Dec. 31, 1965 [Dec. 31, 1964], No. 55496/65. Heading H1D. In a process of aluminizing the phosphor screen of a cathode-ray tube in which the screen is rinsed with an aqueous solution, a volatile lacquer film is applied, the aluminium layer is deposited and the lacquer film then removed by baking, the aqueous solution contains not more than 20% by volume of a surface tension reducing water-soluble organic solvent in the form of certain alcohols and ketones, specifically one or more of the following:-methanol, ethanol, 1-propanol, 2-propanol, 2 - methyl - 1 - propanol, 1 - butanol, 2 - butanol, 3 - methyl - 1 - butanol, 2 - methyl - 2 - butanol, 1 - pentanol, 2 - pentanol, 2 - propanone, 2-butanone, and 2-pentanone. Basically the organic solvent has a chain of 1, 2, 3, 4 or 5 carbon atoms containing a hydroxyl or carbonyl group and has a melting point below - 11‹ C. and a molecular weight within the range of 32.0 to 89.0. Preferred examples are given. The lacquer film is applied by spray or slurry and the aluminium layer by vapour deposition. The invention is preferably applied to a multiphosphor colour screen.
