  • Publication number: 20040002022
    Abstract: A color image forming method is disclosed, comprising exposing a silver halide color photographic material and developing the exposed photographic material at 43 to 180° C. to form a color image, wherein at least one light-sensitive layer comprising a silver halide emulsion comprising tabular silver halide grains having an average aspect ratio of at least 8. There is also disclosed a digital image forming process, wherein image recording information of the photographic material which was formed by use of the color image forming method is coverted to digital image information through an image sensor.
    Type: Application

  • Publication number: 20030203324
    Abstract: A color image forming method is disclosed, comprising exposing a silver halide color photographic material and developing the exposed photographic material at 43 to 180° C. to form a color image, wherein when the photographic material is exposed so that the light-sensitive layer has a transmission density of a minimum density plus 0.1, the light-sensitive layer comprises dye-clouds having an average diameter of 3.0 to 20.0 &mgr;m. There is also disclosed a digital image forming process, wherein image recording information of the photographic material which was formed by use of the color image forming method is converted to digital image information through an image sensor.

  • Patent number: 6593070
    Abstract: An image formation process is disclosed, comprising overlapping an imagewise exposed silver halide photographic material onto a processing element with an aqueous medium being present between the photographic material and the processing element to perform development, thereby forming an image in the photographic material, wherein the aqueous medium contains at least a color developing agent or a precursor thereof, and the aqueous medium having a viscosity of 10.0 to 15000 cp at 25° C.
    Type: Grant

  • Patent number: 6245498
    Abstract: A silver halide emulsion is disclosed, comprising tabular grains having an aspect ratio of 5 or more, the tabular grains further having dislocation lines of 30 or more per a grain, in a fringe portion of the grain and the tabular grains each containing silver iodide, the content of which gradually and continuously varies in the direction of from the grain center to the edge.

  • Patent number: 6120980
    Abstract: A silver halide emulsion is disclosed, comprising silver halide grains having a variation coefficient of a grain diameter of 20% or less, at least 50% of total grain projected area being accounted for by tabular silver halide grains having an aspect ratio of 2 or more, said tabular grains each having 10 or more dislocation lines per grain in the peripheral region of the grain and having a variation coefficient of dislocation line length of 20% or less. A color photographic material by use of the emulsion is also disclosed.
