Abstract
A process of making emulsion for photographic material being prevented from coarse oil globules mixed-in which causes visible spots on the final products is disclosed. Before mixing and emulsifying oil phase and water phase in an emulsifying tank, said two phases are pre-mixed air-tightly in an in-line-mixer to minimize the above mentioned trouble.
