    摘要： A process and apparatus for producing silver halide grains wherein by removing water, etc., from a liquid containing fine, silver halide grains formed in a mixer and being added to a reaction vessel, the yield of the silver halide grains grown in the reaction vessel per unit amount of the raw materials used is increased. Also, by removing a portion of the water, used for the dilution, from the liquid being added to the reaction before the addition thereof, the amount of diluting water effective for the formation of silver halide fine grains in the mixer is increased, to thereby form finer silver halide grains in the mixer.

    摘要： A method for forming a photographic element includes steps of heating an emulsion containing grains of a radiation sensitive silver haloiodide to form a first melt, heating an emulsion containing grains of a silver salt effective to enhance the photographic properties of the silver haloiodide emulsion to form a second melt, and coating the first and second melts onto a photographic support to form an image recording layer. The silver salt grains are substantially insensitive to radiation at wavelengths at which said silver haloiodide grains are sensitive. The coating step is preferably carried out by blending the first and second melts together, then immediately coating the silver haloiodide emulsion onto the support. In a preferred embodiment, the silver salt is essentially silver chloride in the form of relatively fine cubic grains, and the silver haloiodide is in the form of tabular grains larger than the cubic grains. The foregoing procedure unexpectedly improves the speed of the resulting photographic element. For color reversal photographic elements, the melt containing the fine silver salt grains is conveniently the coupler melt.

    摘要： An improved process for preparing silver halide emulsions by precipitation of silver halide grains in a single reaction vessel comprising a dispersing medium is disclosed. The process comprises forming a silver halide emulsion by adding silver salt and halide salt solutions in a dispersing medium contained in a reaction vessel to form silver halide nuclei and allowing said silver halide nuclei to grow in said reaction vessel. The improvement comprises, during a pause of addition of silver salt and halide salt solutions, reducing the volume of silver halide emulsion by continuously delivering the silver halide emulsion to a cleaning stage for the partial removal of dispersing medium and any salt soluble therein and returning the silver halide emulsion to the reaction vessel.
