摘要： PURPOSE:To enhance an effect of improving photographic characteristics due to metal doping by specifying the distribution of a polyvalent metal compound in silver halide grains. CONSTITUTION:This silver halide photographic emulsion comprises silver halide grains uniformly distributed with the polyvalent metal compound in the >=50% of the volume of each grain, and as this metal compound, the metal compounds of Mg, Al, Ca, and the like are preferably used, and preferably selected from single salts and metal complex salts, and in the case of metal complexes, hexa-, penta-, tetra-, and di-coordinated complexes are preferable, and especially, octahedral hexacoordinated and hexacoordinated plane complexes. This emulsion can be obtained, as one example, by maintaining a dopant concentration constant at the time of growing silver halide grains by >=50 of the grain volumes, preferably, keeping the concentrations of the dopant as well as halide ions or silver ions constant.

摘要： PROBLEM TO BE SOLVED: To provide high sensitive illuminance reciprocity failure characteristics by making silver halide grains, having a surface on which a development start point exists at the center of a specific area, accounts for a specific amount. SOLUTION: Silver halide grains have a surface on which a development start point exists in a center part area corresponding to 50% of the surface area including a center point. Desirably the development start point exists in the center part area corresponding to 30% of the area. Further, it exists in the center part area corresponding to 15% of the area. To provide silver halide grains that a site of the development start point and a number of grains are controlled, the silver halide emulsion that contains silver halide grains whose iodide content at a core part is less than those at a shell part is provided, a silver halide solvent is added before adding the chemical sensitizer and the sensitizing dye when chemically sensitizing and spectral sensitizing the silver halide emulsion. The silver halide grains desirably accounts for 60% or more of the total silver halide emulsion grains, further desirably, 80% or more.
