摘要：
A spectrally sensitised photographic silver halide emulsion which is super-sensitised with an aromatic complex having a central transition metal atom which is present in a valence state which is not the highest possible for the metal concerned and which complex contains at least one non-aromatic complex ligand, is distinguished by increased sensitivity.
