PROBLEM TO BE SOLVED: To provide a silver halide photographic sensitive material containing a fine dispersion of a hydrophobic photographically useful compound excellent in suitability to manufacture. SOLUTION: This invention relates to a method for dispersing a water-insoluble phase substantially comprising a hydrophobic photographically useful compound having a melting point of <100°C and an aqueous solution of an organic solvent having a high boiling point in water or in a hydrophilic colloidal composition, the method includes a step of dispersing the hydrophobic photographically useful compound in water or in a hydrophilic colloidal composition at a temperature close to the melting point of the compound to obtain a dispersion, a step of cooling the dispersion to 5-60°C, and a step of storing the dispersion, and the water-insoluble phase is prepared and used in such a way that the viscosity of the water-insoluble phase at the storage temperature of the dispersion becomes 100 to <1,000,000 P at a shear rate of 10 s<SP>-1</SP>.
