Abstract

A silver halide photographic element comprises at least one silver halide emulsion layer comprising 3D emulsion grains having an equivalent spherical diameter of less than or equal to 0.35 µm and said layer further comprises a fragmentable electron donor compound of the formula X-Y' or a compound which contains a moiety of the formula -X-Y'; wherein
  • X is an electron donor moiety, Y' is a leaving proton H or a leaving group Y, with the proviso that if Y' is a proton, a base, β-, is covalently linked directly or indirectly to X, and wherein:
  • 1) X-Y' has an oxidation potential between 0 and about 1.4 V; and
  • 2) the oxidized form of X-Y' undergoes a bond cleavage reaction to give the radical X* and the leaving fragment Y'; and
  • 3) the radical X* has an oxidation potential ≤-0.7V (that is, equal to or more negative than about -0.7V).
