ABSTRACT:
A silver halide photographic material having formed on a support two or more layers that are sensitive to the lights of substantially the same spectral region but different in light sensitivity is disclosed. At least one of the layers other than the one having maximum light sensitivity contains at least 40 mg, per 100 g of silver, of a water-soluble compound containing an element of Group VIII of the periodic table which has a molecular weight of 100 or more. The material has a wide latitude for exposure, and this latitude will not vary greatly with time during storage.
