Abstract

Abstract A method of processing a photographic material which contains a light-sensitive silver halide emulsion layer having associated therewith a blocked photographic agent capable of releasing a photographically useful agent by ring cleavage of a 4- to 7-membered ring containing at least one carbonyl group in the presence of a hydroxylamine, whereby both high stability of the photographic material upon storage and timely release of the photographically useful agent upon processing are achieved.
