In the tabular silver halide emulsion used in the present invention, the average aspect ratio means the average value of the ratio of the diameter to the thickness of the silver halide grains. That is, it is the average value of the values obtained by dividing the diameter of each silver halide grain by the thickness. Here, the diameter means the diameter of a circle having an area equal to the projected area of a grain when the silver halide emulsion is observed with a microscope or an electron microscope. Therefore, the average aspect ratio of 5: 1 or more means that the diameter of this circle is 5 times or more the thickness of the particles.

In the tabular silver halide grains used in the silver halide emulsion of the present invention, the grain size is 5 to 15 times, particularly preferably 5 to 10 times the grain thickness. The proportion of tabular silver halide grains in the projected area of all silver halide grains is 85% or more.

By using such an emulsion, a silver halide photographic light-sensitive material having an excellent sharpness can be obtained. The sharpness is excellent because the light scattering by the emulsion layer using such an emulsion is extremely small as compared with the conventional emulsion layer.
This can be easily confirmed by those skilled in the art by experimental methods that can be routinely used. The reason why the light scattering of the emulsion layer using the tabular silver halide emulsion is small is not clear, but it is considered that the main surface of the tabular silver halide emulsion is oriented parallel to the support surface.

The thickness of the particles is preferably 0.5 μm or less. Here, the tabular silver halide grain diameter means the diameter of a circle having an area equal to the projected area of the grain. Also, with the thickness of the particles,
It is represented by the distance between two parallel planes constituting a tabular silver halide grain.

In the present invention, more preferred tabular silver halide grains have a grain thickness of 0.3 μm or less and an average (diameter /
The thickness) is 5 or more and 10 or less. When the amount is more than this, the photographic performance may be abnormal when the light-sensitive material is bent, tightly wound, or touched with a sharp object, which is not preferable.

Any of silver bromide, silver chlorobromide, silver iodobromide, and silver chloroiodobromide may be used, but silver bromide, silver iodobromide containing 15 mol% or less of silver iodide, or 50 mol% or less of silver chloride may be used. Silver chloroiodobromide and silver chlorobromide having a silver iodide content of 2 mol% or less are more preferable, and the composition distribution in the mixed silver halide may be uniform or localized.

The particle size distribution may be narrow or wide.

The various treatment liquids in the present invention are used at 10 ° C to 50 ° C. A temperature of 33 ° C to 38 ° C is standard, but it is possible to raise the temperature to accelerate the treatment and shorten the treatment time, and conversely to lower the temperature to improve the image quality and improve the stability of the treatment liquid. it can. Further, in order to save silver in the light-sensitive material, processing using cobalt intensification or hydrogen peroxide intensification described in West German Patent No. 2,226,770 or US Pat.

If necessary, a heater, a temperature sensor, a liquid level sensor, a circulation pump, a filter, a floating pig, a squeegee, etc. may be provided in each treatment bath.

In addition, in the case of continuous processing, a constant finish can be obtained by using a replenisher of each processing solution to prevent the composition of the solution from varying. The replenishment amount can be reduced to half or less than the standard replenishment amount for cost reduction.

(Samples 105 to 112) C-8 of the seventh layer and the eighth layer of Samples 101 to 104 was replaced with C-11
Samples 105 to 108 and Samples 109 to 112 were prepared by substituting 0.4 times mol and 1.7 times mol of the compound (30) of the present invention.

The samples 101 to 112 thus obtained were given uniform blue light, imagewise exposed with green light, and then subjected to the developing treatment as shown below. As a result, a magenta color as shown in FIG. 1 was obtained. An image characteristic curve 1 and a yellow color image density 2 were obtained. Here, ΔD _B is the unexposed area (A

That is, in FIG. 1, curve 1 represents the characteristic curve for the magenta color image of the green light sensitive emulsion and curve 2 represents the yellow image density of the blue light sensitive layer upon uniform blue exposure. Point A represents a fog portion of the center image, and point B represents an exposure amount portion which gives a magenta density of 2.0.

The Theory of Photographic Process 3r
This was followed by the method described in d edd (published by Matsuku Milan: published by Mies). The relative sensitivity was calculated from the magenta density value of a sample processed by performing imagewise exposure with white light.

On the other hand, the emulsion-coated surface of the sample was placed inside, the sample was bent to an angle of 40 ° for 10 seconds, and then imagewise exposure was performed with white light. Then, the same development process was performed, and the optical density of the bent portion and the non-bent portion was measured, and the density abnormality at the time of bending was judged based on the difference in the density.

Color development processing was carried out at 38 ° C. according to the processing steps described below.

Subsequently, a predetermined amount of an aqueous solution 1 in which 145 g of silver nitrate was dissolved and an aqueous solution of a mixture of potassium bromide and potassium iodide were added in equimolar amounts at a predetermined temperature and a predetermined pAg at an addition rate close to the critical growth rate. A core emulsion was prepared. Furthermore, the remaining silver nitrate aqueous solution and an aqueous solution of a mixture of potassium bromide and potassium iodide having a different composition from the preparation of the core emulsion were added in equimolar amounts at an addition rate near the critical growth rate to coat the core. The core / shell type added silver bromide tabular emulsions E to F were prepared.
