摘要： An improved silver halide precipitation process of preparing a dispersion of silver halide grains is disclosed. The process comprises forming a radiation-sensitive silver halide dispersion by reacting silver and halide salts in solution within a dispersing medium to form silver halide grain nuclei within the dispersing medium and allowing silver halide grain growth to occur in a reaction vessel in which the silver halide grain nuclei and the dispersing medium are present. The improvement comprises, during silver halide grain growth, withdrawing a portion of the dispersing medium from the reaction vessel through an ultrafiltration membrane while retaining the silver halide grains within the dispersing medium remaining within the reaction vessel.

摘要： Variation of charged amount accompanying production amount change does not affect photograph performance, a flexible production of an optimal amount corresponding to commercial scene needs may be performed, and a silver halide emulsion having monodispersibility may be produced with sufficient productivity. In the first line a series of continuous operations are performed that a silver salt aqueous solution, a halide salt aqueous solution, and a hydrophilic dispersion medium aqueous solution are mixed and reacted to generate silver halide grain nuclei, and a mother liquor containing the silver halide grain nuclei is stored in cooled state until a amount of production reaches a desired production amount of a silver halide emulsion. A series of continuous operations are performed at least once that when an amount of formation reaches the desired production amount, the cooled mother liquor is ultra-filtrated in the third line to eliminate, to dehydrate, and to concentrate unnecessary salt generated in the formation reaction, and the mother liquor after ultra-filtrated and an addition liquid containing silver halide ultrafine grains prepared in the second line are instantaneously mixed continuously to grow the silver halide grain nuclei.
