Silver halide emulsions predominantly chloride containing silver halide grains with surfaces chemically sensitized and interiors free fromchemical sensitization and the use thereof in reversal processes
Abstract
Abstract IMPROVED PROCESSES ARE DISCLOSED FOR OBTAINING POSITIVE IMAGES IN UNFOGGED, SILVER HALIDE EMULSIONS WHEREIN A PHOTOGRAPHIC ELEMENT COMPRISING A SUPPORT AND SAID EMULSION ARE IMAGE-WISE EXPOSED AND THEN EITHER (A) DEVELOPED IN A SILVER HALIDE SURFACE DEVELOPER IN THE PRESENCE OF A FOGGING AGENT, (B) LIGHT-FLASHED DURING DEVELOPMENT IN A SURFACE DEVELOPER, (C) DEVELOPED IN A SILVER HALIDE AERIAL FOGGING SURFACE DEVELOPER OR (D) BATHED IN A SURFACE-IMAGE STABILIZER BATH FOLLOWED BY LIGHT-FLASHING BEFORE OR DURING DEVELOPMENT IN A SILVER HALIDE SURFACE DEVELOPER. IN ONE ASPECT, IMPROVED SILVER HALIDE EMULSIONS WHEREIN THE HALIDE IS PREDOMINANTLY CHLORIDE ARE DISCLOSED FOR USE IN THE ABOVE PROCESS.
