一、第一种方法本报告讨论了卤化银感光材料的一种加工方法,这种方法包括定影加工步骤,用特殊卤离子作定影剂。但用含卤离子的定影剂在水洗时由于卤化银重结晶使加工出来的胶片不透明。采用下列方法可以克服上述缺点。这种方法所用的定影液含有至少1.3克分子/升碘离子或至少3克分子/升溴离子。溶液中还有一种在分子结构上带有吡咯烷酮的聚合物。 First, the first method This report discusses a processing method of silver halide photographic materials, this method includes a fixing process steps, with special halide ions as a fixer. However, with a halide-containing fixer, the processed film is opaque due to recrystallization of the silver halide during washing. The above method can overcome the above shortcomings. The fixatives used in this method contain at least 1.3 moles iodide ions or at least 3 moles bromine ions per liter. There is also a polymer with pyrrolidone in its molecular structure.
