A silver halide color photographic material is disclosed, comprising support having thereon a yellow image forming layer, a magenta image forming layer and a cyan image forming layer, each of which contains light sensitive silver, halide, wherein when the photographic material having been exposed to light for 10 to 10 sec. per pixel and processed, an effective tone range of a color image obtained in each of the color image forming layers is 0.65 to 0.84.

Silver halide color photographic material

A method for forming an image is disclosed. The method comprises the steps of exposing a photographic image forming medium by scanning by a light beam, and developing the photographic image forming medium to form an image,

Method for forming method

A light-sensitive silver halide photographic material is disclosed, comprising a reflective support comprising a resin layer-coated base paper and having thereon a silver halide emulsion layer , wherein a hydrophilic colloid layer containing a white pigment is provided between the resin layer and the silver halide emulsion layer; the resin layer having an uneven surface; and a Wiener spectrum of the silver halide photographic material satisfying the following relation,

Light-sensitive silver halide color photographic material

A light-sensitive silver halide photographic material is disclosed. The light-sensitive material comprises a support having thereon a silver halide emulsion layer, and the silver halide emulsion layer comprises silver halide grains having a silver chloride content of not less than 95 mol %. The emulsion is optically sensitized by addition of a dispersion of an optical sensitizer comprising a medium and particles of the dye dispersed in the medium. The ratio of silver to gelatin (Ag/Gel) in the emulsion at the time of addition of the dispersion of the dye is 2 to 8.5.

Silver halide photographic emulsion and light-sensitive silver halide

A silver halide color light-sensitive material is disclosed. The light-sensitive material comprises a support and a silver halide emulsion layer provided on the support. The emulsion layer comprises silver halide grains which have been formed in the presence of a complex of rhenium, molybdenum, iridium, rhodium, ruthenium, osmium, cadmium, zinc, palladium, platinum, gold, iron, nickel, cobalt, tungsten, or chromium each having at least one cyanate ligand, isocyanate ligand or fluminate ligand. The light-sensitive material is high in speed, low in fog and excellent in reciprocity low failure characteristics.

Silver halide color photographic light sensitive material

Disclosed is A silver halide photographic light-sensitive material formed by coating at least one silver halide photographic emulsion layer on a reflective support having irregularities at random on the surface, wherein the intensity of Wiener spectrum of the reflective support at a spatial frequency of f cycles/mm given by the expression f=1120/CS is less than 90% of the geometric mean of the intensity at a spatial frequency of f/2 cycles/mm and the intensity at a spatial frequency of 2f cycles/mm when the coating speed for said silver halide emulsion layer is CS (m/minute). The silver halide photographic light-sensitive material according to the invention, has a proper gross and a high capability of depicting details of an image.
