    Abstract: This invention is directed to forming two silverless continuous tone photographic images from a sandwich comprising two UV transparent outer support layers and a pigment or dye filled photosensitive composition as the inner layer by exposing said composition to actinic radiation e.g., UV light through imagebearing transparencies adjacent each outer support layer to selectively insolublize the UV exposed areas of said composition, peeling said outer support layer apart and removing soluble portions of the composition in the unexposed areas thereby forming a silverless, continuous tone, photographic image on each outer support layer.

    Abstract: 1,160,666. Polythioethers. INVENTA A.G. FUR FORSCHUNG UND PATENTVERWERTUNG, ZURICH. 4 June, 1968 [9 June, 1967], No. 26484/68. Heading C3R. Polythioethers containing units of formula where R and R 1 are aromatic radicals, are obtained by reacting an alkali metal or alkaline earth metal salt of an aromatic dithiol with an aromatic dihalogen compound having at least three carbon atoms between the halogen atoms, the aromatic radical being free from electronattracting groups in o- or p-positions with respect to the halogen atoms, in a polar solvent at elevated temperature. In examples, polymers are obtained by heating potassium, lithium and sodium salts of diphenyl ether 4,41- dithiol with p-dibromo-benzene, p-dichlorobenzene and 4,4 1 -dibromodiphenyl ether, in N-methylpyrrolidone. Other salts mentioned are those of diphenyl sulphide dithiol, diphenylmethane dithiol and 4,4 1 -dimercaptodiphenyl, and other dihalogen compounds are 1,3- dibromo - benzene, 1,4 - dichloronaphthalene, 4 - chloro - 4 1 - bromodiphenyl, 4,41 - diiododiphenyl - methane and 4,41 - dichlorodiphenyl sulphide. A catalyst, e.g. copper, copper oxides, copper salts, N-bromosuccinimide or N-bromo-phthalimide, may be present in the reaction.
