Abstract

6652. Kent, T. O., and Oppenheimer, Son, & Co. March 19. Processes.-In preparing tablets of photographic compositions and reagents such as are used for developing, toning, &c., the different substances, which would otherwise react upon each other, are separated by interposing layers of material inert with respect to each. The tablet may be enclosed in a light and airtight capsule or covering of inert material such as gelatine, tin-foil, &c. For example, a developing - composition containing the developing compound and a carbonate is made up in layers, with a layer of sulphite of soda interposed.
