摘要： Compositions which are effective as photographic bleach-fixes can be prepared from solutions containing substantial amounts of reduced oxidant, e.g., ferrocyanide, and dissolved silver by reaction with iodine which oxidizes the reduced oxidant and precipitates silver as silver iodide. This can be used for effective regeneration of photographic bleach-fix compositions.

摘要： Chelated stannous ion silver halide nucleating agents are used in photographic reversal processes. The nucleating agents are useful in reversal developer solutions or in prebaths employed prior to reversal development. The nucleating agents are especially useful for processing multilayer color products where the emulsion layers contain color couplers or for selective reversal processing of multilayer color products where the couplers are present in the color developing solutions.

摘要： MONOCYLIC AND BICYCLIC PHENOLS CONTAINING AT LEAST ONE SULFONAMIDO GROUP, ESPECIALLY AN AROMATIC SULFONAMIDO GROUP, AND A NITROGEN CONTAINING RADICAL (WHICH MAY BE A SULFONAMIDO GROUP), ARE DESCRIBED. THEY ARE PHOTOGRAPHIC SILVER HALIDE DEVELOPING AGENTS FOR BLACK-AND-WHITE DEVELOPMENT, BUT ARE ESPECIALLY USEFUL AS COMPETING OR BALANCING DEVELOPING AGENTS IN PHOTOGRAPHIC COLOR DEVELOPERS TO CONTROL AMOUNT OF DYE PRODUCED BY THE COLOR DEVELOPER, ESPECIALLY THOSE CONTAINING THE COLOR-FORMER OR COUPLER.

摘要： IONIC BORON HYDRIDES HAVING AT LEAST TWO BORON ATOMS PER MOLECULE, SUCH AS, FOR EXAMPLE, TETRAMETHYLAMMONIUM OCTAHYDROTRIBORATE, ARE EFFECTIVE SILVER HALIDE NUCLEATING AGENTS FOR USE IN NUCLEATING BATHS OR DEVELOPER SOLUTIONS EMPLOYED IN PHOTOGRAPHIC PROCESSING. THESE COMPOUNDS ARE SUPERIOR NUCLEATING AGENTS, AS COMPARED TO THE ALKALI METAL BOROHYDRIDES OR THE BORANES USED HERETOFORE FOR THIS PURPOSE, WITH RESPECT TO SUCH FACTORS AS STABILITY IN SOLUTION, EASE OF PROCESS CONTROL, AND IMPROVED SENSITOMETRIC RESULTS.
