Abstract
This invention provides a method of processing a negative color silver halide photographic element comprising taking an exposed color silver halide photographic element with a speed greater than ISO 180 or containing at least one spectrally sensitized silver halide emulsion with a tabularity greater than 100, wherein the photographic element comprises a total amount of incorporated silver and incorporated vehicle of 20 g/m.sup.2 film or less; developing the exposed photographic material; and bleaching the exposed, developed photographic element with a peracid bleach in the presence of a bleach accelerator.
Claims29
A method of processing a negative color silver halide photographic element comprising
- taking an exposed color silver halide photographic element with a speed greater than ISO 180 or containing at least one spectrally sensitized silver halide emulsion with a tabularity greater than 100, wherein the photographic element comprises a total amount of incorporated silver and incorporated vehicle of 20 g/m.sup.2 film or less;
- developing the exposed photographic element;
- and
- bleaching the exposed, developed photographic element with a peracid bleach in the presence of a bleach accelerator which accelerates peracid bleaches.
A method of processing a negative color silver halide photographic element comprising
- taking an exposed color silver halide photographic element with a speed greater than ISO 180 or containing at least one spectrally sensitized silver halide emulsion with a tabularity greater than 100, wherein the photographic element comprises a total amount of incorporated silver and incorporated vehicle of 20 g/m.sup.2 film or less with the amount of vehicle being 2 to 15 g/m.sup.2 and the amount of silver being less than 10 g/m.sup.2 ;
- developing the photographic element;
- and
- bleaching the exposed developed photographic element in a sodium, potassium, or ammonium persulfate bleach in the presence of a bleach accelerator which accelerates peracid bleaches for 20 to 260 seconds, wherein the concentration of the persulfate is 0.01 to 1.0 moles/liter.
