Abstract
A process for producing a silver halide emulsion is disclosed, which comprises disposing a mixer equipped with a first channel and a second channel brought into partial contact therewith; and allowing a silver salt solution (Fluid 1) and a halide solution (Fluid 2) to pass through said first channel and said second channel, respectively, to thin said two fluids into lamellae having an open interface therebetween and having a thickness of 1 to 500 μm in a normal line direction on the contact interface, thereby inducing diffusion, transfer and reaction of silver ions and halogen ions between said two thin layers, and thus forming silver halide grains continuously.
