    摘要: A silver halide emulsion combining the advantages of a strongly monodisperse character with a high silver iodide content can be prepared by mixing a water-soluble silver salt solution with a water-soluble halide solution in the presence of a protective colloid, and thereby forming silver halide grains consisting essentially of silver iodobromide when a tetrazaindene compound is made present during formation of the silver halide grains.

    摘要: There is disclosed a light-sensitive silver halide color photographic material having red-sensitive, green-sensitive and blue sensitive emulsion layers, each layer consisting of two or more layers with different sensitivities on a support, wherein the layers are constituted so as to satisfy the following requirements (A), (B), (C) and (D):

    (A) of the respective emulsion layers having the highest sensitivities among the the red-sensitive, green-sensitive and blue-sensitive emulsion layers, the highest sensitivity blue-sensitive emulsion layer is provided in the side farthest from the support;
    (B) at least the the highest sensitivity red-sensitive emulsion layer and the highest sensitivity green-sensitive emulsion layer are provided between the the highest blue-sensitive emulsion layer and a blue-sensitive emulsion layer with lower sensitivity;
    (C) none of the respective red-sensitive, green-sensitive and blue-sensitive emulsion layers having the lowest sensitivities exists on the side farther than the low sensitivity blue-sensitive emulsion layer from the support; and
    (D) contained in at least one layer of the high sensitivity red-sensitive, green-sensitive and blue-sensitive layers, is a diffusion-resistant compound capable of forming a mobile dye through the coupling reaction with the oxidized product of a chromogenic developing agent.

    The light-sensitive material according to this invention exhibits excellent photographic characteristics such as graininess, sharpness and sensitivity.

    摘要: A process for producing a silver halide photographic emulsion by supplying a solution of a water-soluble silver salt and a solution of a water-soluble halide in the presence of a protective colloid is disclosed, said process comprising, in sequence:
    (A) the step of forming silver halide nuclear grains with a silver iodide content of 0 to 5 mols%, wherein the pH of the mother liquor is maintained at between 2.0 and -0.7 for at least the initial half of the period of said step; (B) the step of forming silver halide seed grains wherein the silver halide grains formed by step (A) above are made into monodisperse, substantially spherical seed grains; and (C) the step of increasing the sizes of the seed grains by addition of a solution of a water-soluble silver salt and a solution of a water-soluble halide and/or fine silver halide grains.
