Abstract (en)

Camera speed color photographic elements are effectively bleached using a peroxide bleaching solution containing critical amounts of peroxide and chloride ion. These elements have predominantly chloride silver halide emulsions that contain less than 2% iodide ion, and are substantially free of a bleaching rate retarding amount of a development inhibitor having a free valence that binds to silver. No vesiculation in the processed element is observed after bleaching.
