    摘要: A control process and apparatus for the formation of silver halide grains comprising a mixer disposed outside of a reaction vessel containing an aqueous protective colloid solution and causing a nucleus formation (nucleation) and/or a crystal growth of silver halide grains. The process and apparatus further include: supplying an aqueous solution of a water-soluble silver salt, an aqueous solution of water-soluble halide(s), and an aqueous solution of a protective colloid to the mixer through supply conduits while controlling the flow rates of the solutions; mixing them while controlling the rotational speed of a stirrer of the mixer to form fine, silver halide grains; and immediately supplying the fine grains into the reaction vessel through a conduit connecting the mixer to the reaction vessel to perform the nucleus formation and/or the crystal growth of the silver halide grains in the reaction vessel. The control process and apparatus further comprise measuring the silver ion potential of the fine grains formed in the mixer or the silver ion potential in the reaction vessel with an electrode, and controlling the flow rate of at least one of the aqueous silver salt solution, the aqueous halide solution, and the aqueous protective colloid solution being added to the mixer, such that the measured value equals a predetermined value.

    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 silver halide photographic emulsion containing tabular silver halide grains which have an aspect ratio of 2 or more and in which dislocations are localized in a center portion of each grain. The tabular silver halide grains have a thickness of less than 0.5 .mu.m and a diameter of 0.3 .mu.m or more and account for at least 50% of a total projected area of the silver halide grains. This emulsion has a high sensitivity and good reciprocity characteristics. In a photographic light-sensitive material having at least two light-sensitive silver halide emulsion layers having different color sensitivities on a support, the above tabular silver halide photographic emulsion and at least one type of a coupler which is coupled with an oxidant of a color developing agent to develop a color are added to at least one of the emulsion layers, thereby obtaining a photographic light-sensitive material having a high sensitivity and good reciprocity characteristics.

    摘要: A process for manufacturing uniform silver halide grains, which comprises the steps of:(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 vessel i 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.
