摘要:
A tabular silver halide emulsion having a Cl content of 10% or more, which has high covering power, high sensitivity and low fogging property, prepared by adding fine silver halide grains in an amount corresponding to 20% or more of the total silver amount under the condition of pH 5.5 or more and/or pCl 1.6 or more during the course of growth of crystals after nucleation to allow the crystals to grow, and a photographic material using the same, and further a method for developing the photographic material and an image-forming method.
