percent chloride, based on silver, and having greater than 50
percent of their surface area provided by {100} crystal faces,
wherein
(i) a first fraction which comprises from 10-90 wt% of the
silver halide grains, based on total radiation-sensitive silver
halide in the layer, consists of grains which have a central
portion accounting for up to 99 percent of total silver which
contains at least 10-7 mole of a hexacoordination metal complex
which satisfies formula (I) per mole of silver and less than 10-10
mole of a hexacoordination metal complex which satisfies formula
(II) per mole of silver, and
(ii) a second fraction which comprises from 10-90 wt% of the
silver halide grains, based on total radiation-sensitive silver
halide in the layer, consists of grains which have a central
portion accounting for up to 99 percent of total silver which
contains at least 10-10 mole of a hexacoordination metal complex
which satisfies the formula (II) per mole of silver and less than
10-7 mole of a hexacoordination metal complex which satisfies the
formula (I) per mole of silver:
(I) [ML6]n
wherein n is zero, -1, -2, -3 or 4,
M is a filled frontier orbital polyvalent metal
ion, other than iridium, and
L6 represents bridging ligands which can be
independently selected, provided that at least four of the
ligands are anionic ligands, and at least one of the ligands is a
cyano ligand or a ligand more electronegative than a cyano
ligand;
[TE4(NZ)E']r
where T is a Os or Ru;
E4 represents bridging ligands which can be
independently selected;
E' is E or NZ;
