Title: Heat-processable photosensitive material
IPC: G03C1/498
Filed: 1975-05-22
Abstract: 1498406 Heat-processable material KODAK Ltd 22 May 1975 [30 May 1974] 23995/74 Heading G2C A photothermographic material comprises, incorporated in a layer or layers coated on one side of a support, an oxidation/reduction imageforming system comprising (a) a light-insensitive silver salt of an organic acid and (b) a sulphonamidophenol reducing agent, (c) a photo-sensitive compound which on exposure to actinic radiation forms centres which catalyze the thermally-induced image forming reaction of (a) and (b), and (d) a calcium or magnesium salt of a long-chain fatty acid (i.e. a fatty acid containing at least 10 carbon atoms) or a calcium or magnesium compound and a long-chain fatty acid which react to produce such a salt when the material is heated to bring about the formation of an image. The term "sulphonamidophenol" is used to include sulphonamidonaphthols as in Specification 1433055. The salt reduces the rate of print-up in background areas. Preferred salts have 12 to 22 carbon atoms, stearic and behenic acid salts being suitable. Conveniently the same fatty acid is used in forming both the silver and the calcium or magnesium salts. A mixed metal soap (from the fatty acid and less than the equivalent amount of alkali metal hydroxide and calcium or magnesium compound) can be used.

Abstract: 848,844. Indicating-apparatus. HORNE, R. F. (Roggan, F. H.). July 30, 1957, No. 24125/57. Class 106 (4). [Also in Group XI] The dial 23 of an instrument mounted in a panel 18 is illuminated by a lamp 20 whence all rays projected from the face Y of a prism 15 are directed toward the dial 23. The angular disposition of the faces X, Y of the prism 15 are suitably related to ensure this result having regard to the refractive index of the material, e.g. Lucite. In order to concentrate a beam on a particular area the faces X, Y may be curved to form a segment of a lens. Lamps 20 lie between front and rear opaque panels 18, 19 which, together with an opaque, resilient gasket 21 and a black, roughened coating 17, seal the assembly against leakage of light. A panel 24 of a fluorescent plastic may be inserted between the panels 18, 19 to improve the concentration and distribution of light on the face X and the edge 25 may be bevelled to increase illumination near the centre of the dial. The light-conducting panel 24 may occupy the whole space between the front and rear opaque surfaces of the panel and itself carry the lamps 20.
