Process for preparing silver halide grains |
| abstract |
A process for manufacturing uniform silver halide grains, which comprises the steps of:n (A) providing a mixer vessel and a reactor vessel, the mixer vessel being separate from the reactor vessel and the reactor vessel having contained therein an aqueous protective colloid solution and in which silver halide grains are grown; (B) feeding an aqueous water-soluble silver salt solution, an aqueous water-soluble halide solution and an aqueous protective colloid solution into the mixer vessel; (C) forming a fine silver halide grain-containing solution by mixing the thus fed solutions in the mixer vessel; (D) immediately feeding the thus formed fine silver halide grain-containing solution into the reactor vessel; and (E) stirring said solution in the reactor vessel to grow uniform silver halide grains therein. By prohibiting the addition of the silver ions and the halide ions to the reactor vesselin the form of aqueous solutions, and the addition of the aqueous protective colloid solution containing the silver halide grains from the reactor vessel to the mixer vessel, formation and growth of uniform silver halide grains is achieved. An apparatus for performing the process of the present invention is also disclosed herein. |
