Emulsification and dispersion method of hydrophobic, photographically useful compound

摘要

An emulsification and dispersion method of a hydrophobic, photographically useful compound comprising dispersing a water-insoluble phase containing the hydrophobic, photographically useful compound in water or in a hydrophilic colloid composition, wherein the water-insoluble phase at a temperature at which the prepared dispersion is stored may have a viscosity of from 100 poise or more to less than 1,000,000 poise at the shear rate of 10 sec-1. According to the present invention, a silver halide photographic material comprising a fine dispersion of a hydrophobic, photographically useful compound and having an excellent production suitability can be obtained.
