Embodiment 1-1

[0250] Embodiment 1-1 (preparation of sensitive blue layer emulsion BH-1)

[0251] High chloride cubic silver grains were prepared using simultaneous addition of mixed silver nitrate, sodium chloride, and potassium bromide (0.5 mole percent per mole of finished silver halide) to stirred deionized distilled water containing deionized gelatin. In this preparation, K 2 [IrCl 5 (5-methylthiazole)]. From the step of adding 82% to 90% of the total amount of silver nitrate, start adding K 4 [Fe(CN) 6 ]. In addition, from the step of adding 83% to 89% of the total amount of silver nitrate, start adding K 2 [IrCl 5 (H 2 O)] and K[IrCl 4 (H 2 O) 2 ]. At the step where 94% of the total amount of silver nitrate was added, potassium iodide (0.27 mol% per mole of silver halide completed) was added with vigorous stirring. The emulsion grains thus obtained were monodisperse cubic silver bromide chloride grains having a side chain length of 0.50 μm, a coefficient of variation of 8....

Embodiment 1-2

[0548] (Preparation of Blue Sensitive Silver Halide Emulsion Grains BH-4)

[0549] To a 2% limed aqueous gelatin solution was added 1.2 g of sodium chloride and the pH was adjusted to 4.3 by adding acid. This aqueous solution was mixed with an aqueous solution comprising 0.025 moles of silver nitrate and a total of 0.025 moles of sodium chloride and potassium bromide at 41° C. under vigorous stirring. An aqueous solution containing 0.005 mol of potassium bromide was then added thereto, followed by an aqueous solution containing 0.125 mol of silver nitrate and an aqueous solution containing 0.12 mol of sodium chloride. The resulting solution was heated to 71°C and mixed with an aqueous solution containing 0.9 molar silver nitrate, an aqueous solution containing 0.9 molar sodium chloride, and 2.5×10 -7 moles of iridium compound, K 2 [IrCl 5 (5-methylthiazole)] while maintaining a pAg of 7.3. Over 5 minutes, an aqueous solution containing 0.1 mol of silver nitrate and an aque...

Embodiment 2-1

[0565] (Preparation of blue sensitive layer emulsion BH-11)

[0566] High chloride silver cubic grains were prepared by simultaneously adding mixed silver nitrate, sodium chloride, and potassium bromide (0.5 mol% per mole of finished silver halide) to deionized distilled water containing deionized gelatin. In this preparation, K is added in a step where 60% to 80% of the total silver nitrate is added 2 [IrCl 5 (5-methylthiazole)]. Add K in steps where 80% to 90% of the total amount of silver nitrate is added 4 [Fe(CN) 6 ]. In addition, K was added in the step of adding 83% to 88% of the total silver nitrate 2 [IrCl 5 (H 2 O)] and K[IrCl 4 (H 2 O) 2 ]. After 94% of the total amount of silver nitrate had been added, potassium iodide (0.27 mol% per mole of silver halide completed) was added under vigorous stirring. The emulsion grains thus obtained were monodisperse cubic silver bromide chloride grains having a side chain length of 0.50 μm, a coefficient of variation ...

Abstract

The present invention provides a silver halide color photosensitive material, having, on a transparent support, at least one each of yellow-, cyan-, and magenta-color-forming photosensitive silver halide emulsion layers, and photosensitive silver halide emulsion layer containing a coupler that forms a dye having its absorption maximum at a wavelength longer than 730 nm upon reaction with an oxidized product of a developing agent, wherein the yellow-color-forming photosensitive silver halide emulsion layer contains photosensitive silver halide grains having an average grain size of 0.4 m or below and a silver chloride content of 95 mole% or above based on total silver in the grains, and wherein the photosensitive silver halide grains include photosensitive silver halide grains whose iodide ion concentrations have their maxima at grain surfaces and decrease gradually toward the interior of the grains; and a method of processing a silver halide color photosensitive material for use in film screening.

Description

technical field [0001] The present invention relates to a silver halide color photosensitive material; more particularly, to a silver halide color film photosensitive material suitable for sufficiently rapid processing through simplification of processing steps and shortening of time. [0002] The invention also relates to silver halide color photosensitive materials which can be processed by simplified and shortened exposure and processing processes, and methods of processing the same. More particularly, the present invention relates to silver halide color cinematographic photographic materials and methods of processing the same. Background technique [0003] In the music industry, during the 1980s, the medium of sound recordings changed from vinyl records to CDs, and analog records were suddenly changed to digital records. In addition, a large-capacity DVD has also entered the market as a medium for recording information including video images. By adopting the perpendicu...
