发明名称 PHOTOGRAPHIC COLOR DEVELOPING COMPOSITIONS WHICH ARE ESPECIALLY USEFUL WITH HIGH CHLORIDE PHOTOGRAPHIC ELEMENTS
摘要 -i- PHOTOGRAPHIC COLOR DEVELOPING COMPOSITIONS WHICH ARE ESPECIALLY USEFUL WITH HIGH CHLORIDE PHOTOGRAPHIC ELEMENTS Photographic color developing compositions which are especially useful in the processing of high chloride silver halide photographic elements are free, or at least substantially free, of bromides: optionally contain a small amount of sulfite; and comprise (1) a primary aromatic amino color developing agent, (2) an N,N-dialkylhydroxylamine, (3) at least one sequestering agent which functions to sequester iron and (4) at least one sequestering agent which functions to sequester calcium. The developing compositions exhibit excellent stability. They also provide minimal development restraint which permits the use of very short development times, as needed for rapid access processing.
