    Abstract: A compound (I) having a carrier moiety (CAR) and a releasable development inhibitor moiety (INH) capable of being released during photographic processing by means of at least one timing group (T) bonded to and releasable from the carrier moiety provides improved images in a photographic silver halide element and process when the inhibitor moiety (INH) comprises (R.sup.1) a non-aromatic, sterically hindered substituent group having (a) a tertiary carbon atom bonded directly to the releasable development inhibitor moiety or (b) a secondary carbon atom bonded directly to the releasable development inhibitor moiety and wherein the secondary carbon atom is not part of an unsubstituted carbocyclic ring containing at least 6 carbon atoms. Such compounds, particularly as couplers, are useful in photographic silver halide materials and processes to provide improved acutance and interimage effects.
