Abstract (en)
A dispersion method of a spectral sensitizer by dissolving an inorganic salt of an amount of at least 0.5% by weight in water which does not substantially contain a surface active agent, an organic solvent, and a silver halide emulsion, adding a spectral sensitizer of an amount of at least 0.5% by weight in the solution, and dispersing the spectral sensitizer as fine solids. By the dispersion method, a dispersion of a spectral sensitizer having a high concentration is obtained.
