Abstract
This invention relates to a silver halide photographic element comprising a reflective support having situated thereon a non-tabular silver halide emulsion layer, said emulsion layer being predominantly silver chloride and being in reactive association with a thiolic compound represented by Formula I: wherein Ar represents a substituted or unsubstituted aromatic or heteroaromatic ring; and EW represents an electron withdrawing group; and with a mercapto azole compound represented by Formula II: wherein Q represents the atoms necessary to form a substituted or unsubstituted five or six-membered heterocyclic ring containing at least one nitrogen atom, and M is a cation.
