摘要：
A light-sensitive silver halide photographic emulsion has been disclosed, said emulsion comprising a binder and core-shell tabular grains, wherein said core is more rich in silver bromide than said shell, characterized in that said grains contain, in the core thereof representing an amount of precipitated silver halide extending up to less than 50% of all precipitated silver halide, a ruthenium complex compound as a sole complex compound providing shallow electron traps.
