| titleOfInvention | Method for producing silver halide emulsion |
| abstract | A silver halide emulsion having an excellent (sensitivity / granularity) ratio is provided. An AgX fine particle having an AgBr content of 50 to 100 mol% is added to a seed crystal emulsion having at least water, a dispersion medium 1, and a silver halide seed crystal, and the fine particle is dissolved and deposited on the seed crystal. In the seed crystal growth method in which the seed crystal is grown by this, the fine particles are formed by adding Ag + and X − to the dispersion medium solution 2 containing the dispersion medium 2, By adding Ag + and X − to the dispersion medium solution 2, the ratio (%) of {100} face of the particle surface = [total area of {100} face / area of the entire surface] × 100 is 10 to 10. After forming 100 seed fine particles, Ostwald ripening and / or further adding Ag + and X − allows the ratio (%) of the total area of {111} faces of the particles to be 10 to 90. The projected diameter increased by only 0.003 to 0.2 μm A method for producing an AgX emulsion of “AgX fine particles”. [Selection figure] None |
