Abstract
780,584. Enamels. SYLVANIA ELECTRIC PRODUCTS, Inc. July 2, 1954 [July 2, 1953], No. 19519/54. Class 56. [Also in Group XL(a)] A coating for a lamp comprises a suspension of intimately mixed finely divided glaze and/or glaze forming material and an electro-luminescent material in a liquid vehicle which forms a gel upon partial drying, the vehicle including a binding material a solvent and a material incompatible with the binding material. After drying the coating is fired first at a temperature below the melting point of the glaze or glaze forming material to remove the binding material and then at a higher temperature to melt the glaze and/or glaze forming material. The following ingredients are specified in one example : glaze-forming powder, ethyl cellulose, mineral oil, chlorinated diphenyl, butanol, xylol, chloroform and an electroluminescent material. The ethyl cellulose binder, the plasticizer and the glaze forming powder are milled in some of the solvents with flint pebbles, the electroluminescent material, the mineral oil and the remainder of the solvents added and further milled for one hour. The suspension is sprayed onto a light transmitting conductive coating of tin oxide, the mineral oil causing gelling of the film in advance of the drying step and preventing flocculation &c. The coatings may be less than 0À001 inches thick and two such coatings may be superimposed. Alternative binding materials are polymethacrylate and nitrocellulose and other plasticizers butyl phthallate and camphor. Amyl acetate, toluol, ethanol and methyl isobutyl ketone may be the solvents and carbon tetrachloride may be used instead of chloroform. The glaze forming material may comprise CaO 3À9 parts, BaO 4-8 parts, ZnO 27À1 parts, SiO 2 21À7 parts, B 2 O 3 26-7 parts No 2 O 8À7 parts, PbO or MnO 0-7 parts and R 2 O 3 5À8 parts where R is a trivalent element not including lead. Specification 773,997 is referred to.
