    摘要： A black-and-white photographic developing composition has improved stability and is more compatible with the environment when discarded. The composition includes one or more ascorbic acid developing agents and is essentially free of hydroquinone and similar derivatives. It comprises a sulfur-containing compound represented by one of the following Structures I, II, III and IV:

            M 1 S-R-CH(NH 2 )-COOM 2      I



            M 1 S-R 1 -COOM 2      II



            R 2 -S-S-R 2      III



            R 3 HN-R 4 -SM 1      IV

    wherein R is a divalent aliphatic linking group having at least 1 carbon atom in the chain, R 1 is phenylene or an unsubstituted alkylene having 1 or 2 carbon atoms, R 2 is a monovalent aliphatic group having at least 2 carbon atoms and comprising a -CH(NHR 3 )-COOM 2 or -(C 1 -C 3 )alkylene-CH(NHR 3 )-COOM 2 group, R 3 is hydrogen, an alkyl group having 1 to 3 carbon atoms or phenyl, R 4 is an alkylene group, a cyclohexylene group, or a phenylene group, and M 1 and M 2 are independently hydrogen, an alkali metal or ammonium ion or methyl group.

    摘要： An radiographic imaging system for making a radiograph by a radiography apparatus using a photographic combination of a silver halide photographic material having light sensitive layers on both sides of the support and an intensifying screen is disclosed, wherein the photographic material exhibits a cross-over of not more than 15%, a specified point gamma value within the specified density range on the characteristic curve when the photographic combination is exposed to X-ray, and wherein the radiography apparatus conducts making a radiograph under the condition that a distance between a focal point of an X-ray tube and the photographic combination is 1.0 to 3.0 m and a distance between an object and the photographic combination is 0.2 to 1.5 m.
