<p>A colour photographic element comprising at least one colour-forming unit sensitive to a particular region of the spectrum comprising a silver halide emulsion layer and, in or adjacent said layer, (1) a development inhibitor releasing developer (IRD) which comprises a hydrazide, sulphonamidophenol, sulphonamidonaphthol, or hydroquinone moiety attached directly or via a linking group to a development inhibitor moiety which compound is oxidisable during silver halide development enabling release of the development inhibitor moiety under alkaline conditions, (2) a sulphonhydrazide colour developing agent, and (3) a colour coupler capable of forming image dye with the sulphonhydrazide during silver halide development.</p> |
