Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a silver halide color reversal photographic light-sensitive material having excellent color reproducibility.

(Prior Art) Usually, a color reversal photographic light-sensitive material has a plurality of silver halide emulsion layers having different color sensitivities, such as a red-sensitive layer, a green-sensitive layer, and a blue-sensitive layer, on a support.

These image-exposed color reversal photographic materials for multicolor subjects are first subjected to black and white silver development in a first development step, and then chemically or optically covered with gold gauze, which remains in a second development step. Shitahaloken Chemical is color developed to form all color images such as cyan, magenta, and yellow. By the way, the dye image S formed in each color-sensitive layer during normal multicolor exposure differs from the dye generated during monochrome exposure, and in the case of color reversal photographic materials, this difference is mainly due to the difference in the dye image S formed in the first development step. This phenomenon occurs due to the movement of development-inhibiting substances such as iodide ions between emulsion layers having different color sensitivities. The difference in color images between multicolor exposure and monochrome exposure caused by such development is discussed in the Journal of the Optical Society of America by Noh Do-sung and Horton, Vol. ri page (/ri 7 published in 2013)
As described in , it is called the multilayer effect or inter-image effect, and is known to be useful for improving sharpness and color reproducibility.

It has been described that the presence of an N-fir-converted thiazoline-cochionized metal produces a significant interimage effect.

/, 13114ft (Iri 7!) is described.

Also, in JP-A-42-//11μ,! -Mercapto/
,! , a method for obtaining favorable interimage effects with 4A-thiadiazole compounds is described.

Furthermore, U.S. Patent No. ≠, OJ'ko, j! No. 3 describes a color reversal photosensitive material produced by the Iori device that allows the movement of iodine ions during development, in which one layer contains haloiodide recording particles capable of forming a latent image, and the other layer contains haloiodide recording particles capable of forming a latent image. A method is described for obtaining good interimage effects by including silver halide grains and silver halide grains whose surfaces are coupled such that they can be developed independently of imagewise exposure.

In addition to the above, for example, in the color development process, a coupler (DIR coupler) that can release a development-inhibiting substance such as a benzotriazole derivative or a mercapto compound during a coupling reaction with an oxidized form of a color developing agent is used. It is also known that an interimage effect can be produced by using a hydroquinone compound that can release a development-inhibiting substance such as an iodide ion or a mercapto compound during development.

(Problems to be Solved by the Invention) In the first development step of the color reversal photosensitive material, the photosensitive silver halide emulsion is developed according to its exposure amount. The silver halide emulsion grains that were not developed at that time are subjected to a color development process through the entire fogging process. In this color development process, all remaining silver halide must be developed to create a color base, so the development activity is affected.

It is highly designed. Therefore, it is virtually impossible to produce a multi-layer effect in the color development process, and in color reversal photosensitive materials, the single-layer effect is substantially determined in the first development process.

This first development step has the effect of dissolving emulsion grains in the developing solution. A single-layer effect is obtained by adjusting this solubility with iodine ions diffused by the development of other layers.

There are many mechanisms that generate the multilayer effect, the most important of which are those described above.

The longer the development time, the greater the effect of this developer in dissolving the emulsion. Therefore, when the processing time of the M/development step is short, it is more difficult to obtain a sufficient multilayer effect with conventional color reversal photosensitive materials than when the processing time is long.

Therefore, it is an object of the present invention to provide a technique that allows a sufficient multilayer effect to be obtained even in a process in which the first development time is short.

For the purpose of the present invention, a first development treatment with a black and white developer and a color development treatment are carried out on the support, one red-sensitive copper halide emulsion layer, one green-sensitive halogen emulsion layer, and a green-sensitive halogen emulsion layer. silver oxide emulsion layer,
A silver halide color reversal photographic light-sensitive material having a blue-sensitive silver halide emulsion layer, characterized in that the at least one light-sensitive emulsion layer contains a silver halide emulsion selected according to the following test method and conditions. This was achieved using silver halide color reversal photographic materials.

<Test method and conditions> The emulsion layer containing the silver halide emulsion grains of the present invention was taken out from the silver halide color reversal photographic light-sensitive material, and the emulsion layer containing the silver halide emulsion grains of the present invention was taken out without changing to a chemical composition other than the silver halide emulsion grains.
A sample is prepared by coating on a support so that the amount of silver coated is 0.2 f7/m2.

After applying wedge light to this coated sample, it was treated with developer A described below, fixed, and the optical density of the developed silver was measured.

Similarly, after developing using the following developer Bye, the optical density of the developed silver is fixed and developed 'fc$1! Determine.

When sensitivity is expressed as the reciprocal of the amount of flashlight required to obtain an optical density of a constant density (fog + 0.2), the sensitivity when processed with developer A is at least 2 times the sensitivity when processed with developer B. Use a silver halide emulsion that is at least twice as large.

It may be silver chloride, silver chloroiodobromide, or silver chloride, but silver bromide and silver iodobromide are preferable. In particular, it is preferable that the silver iodide content is o, oi to 30 mil to 30 mol silver iodobromide, more preferably o, j-io mol.

The halogen composition of the emulsion may be different or the same among the grains, but if an emulsion having the same halogen composition among the grains is used, it is easy to make the properties of each grain uniform. Regarding the halogen composition distribution inside silver halide emulsion grains, there are grains with a so-called uniform structure in which the composition is the same in every part of the silver halide grain, and grains with a core inside the silver halide grain. Surrounding shell (shell) [−
Laminated structure particles with different halogen compositions (layers or multiple layers), or structures with non-layered portions with different halogen compositions inside or on the surface of a particle (if on the particle surface, particles with different halogen compositions) Particles having a structure in which portions of different compositions are joined on the surface can be appropriately selected and used.

In the present invention, it is advantageous to use either of the two types rather than particles of uniform structure.

When silver halide grains have the above-mentioned structure, even if the boundaries between parts with different halogen compositions are clear boundaries, the boundaries may be unclear due to the formation of mixed crystals due to compositional differences. (Also, it may be one that actively has continuous structural changes.)

The average grain size of the silver halide grains of the present invention is 0-2
The grain size is preferably .mu.m or less, and a fine grain emulsion of 0.3 .mu.m or less is particularly preferred.

The size distribution of the silver halide grains of the present invention may be narrow or wide (
However, it is preferable to use a so-called "monodisperse" silver halide emulsion having a narrow grain size distribution in the present invention.

The monodisperse silver halide grains used in the present invention have a grain size distribution tV as defined by the following formula. That is, when the standard deviation S of the particle size distribution is divided by the average particle size r, the value is 0.20 or less.

In the case of spherical silver halide grains, the average grain size referred to here refers to the average diameter of the grains, and in the case of grains with shapes other than cubic or spherical, the projected image is converted to a circular image of the same area. r is defined by the following formula, where the individual grain diameter is ri and the number of grains is ni.

Σn1ri Σni The above particle diameters can all be measured for the above purpose by six methods commonly used in the art. A typical method is Loveland's [Particle Size Analysis Method JA, 8.
T. M., Symposium on Ride Microscopy, 11 years ago, free ~ / 22 pages.Also, ``Theory of the Photographic Process'' by Mies and James, 3rd edition, published by Macmillan (1946). It is described in Chapter 2.

This particle size can be measured using the projected area of the particle or an approximate diameter value.

The silver halide emulsion grains used in the present invention are usually subjected to physical ripening and chemical ripening. Furthermore, those which have been completely spectral sensitized with a spectral sensitizing dye or a supersensitizer may also be used. Additionally, antifoggants and stabilizers may be added to these photographic additives as described in Research Disclosure &/744tJ and A/r7/j.

The most preferred embodiment of the silver halide emulsion grains of the present invention is a fine-grain emulsion with an average grain size of 0.3 μm or less, and the internal region where the maximum value of the latent image distribution exists at a depth of less than 0.03 μm from the grain surface. More preferred for latent image type emulsions.
