Abstract
474,297. Luminescent materials associated with electric discharge devices. GENERAL ELECTRIC CO., Ltd., McKEAG, A. H., and RANDALL, J. T. April 28, 1936, No. 12066. [Class 98 (i)] The luminescence and light-fastness of a rhodamine dye dispersed in a resinous binder are improved by mixing the solid dye with a molten resin in the absence of any solvent adapted to dissolve both the dye and the resin. Resins of the glycerine-phthalic anhydride and formaldehyde-urea types may be used. Resins sold under the Registered Trade Mark "Paralac," and particularly Nos. 1001, 1101 and 1201 are preferred. The dye/resin ratio is 1 : 100 or 1 : 200. When such materials are used with a high pressure metal vapour lamp, they are applied to surfaces other than the envelope of the discharge (e.g. to a reflector fitting), preferably in the molten state, the receptive surface being heated to about 200‹ C. Reference is made to a known method in which phosphorescent or luminous salts are mixed with powdered resin and moulded under heat and pressure ; and also to the process disclosed in Specification 16519/15, [Class 95].
