DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide color photographic light-sensitive material and a color image forming method using the same, and more particularly, to a method for forming an image by a simple and rapid processing with less environmental load. In addition, the use of the silver halide color photographic light-sensitive material for photography, which has high sensitivity and excellent storability, and the use of the silver halide color photographic light-sensitive material, reduces the burden on the environment and enables simple and rapid image formation. The present invention relates to a color image forming method capable of performing the following.

[0002]

2. Description of the Related Art In recent years, photosensitive materials for color photography using silver halide have been increasingly developed, and it is now possible to easily obtain high-quality color images.
For example, in a system usually called a color photograph, a color negative film is used to take a picture, and image information recorded on the developed color negative film is optically printed on color photographic paper to obtain a color print. In recent years, this process has advanced to a high degree, and with the spread of the color lab, which is a large-scale centralized base that produces large amounts of color prints with high efficiency, or the so-called mini-lab, which is a small and simple printer processor installed in stores, But you can easily enjoy color photos.

[0003] In the currently popular color photography system,
The principle of color reproduction by the subtractive color method is adopted. In a general color negative film, a light-sensitive layer using a silver halide emulsion, which is a light-sensitive element having photosensitivity in the blue, green, and red regions, is provided on a transmission support. So-called color couplers forming respective dyes of yellow, magenta and cyan, each of which is a complementary color, are contained in combination. The color negative film that has been imagewise exposed by photography is developed in a color developer containing an aromatic primary amine developing agent. At this time, the exposed silver halide grains are reduced (developed) by a developing agent.
The respective dyes are formed (colored) by a coupling reaction between the oxidized form of the developing agent and the color coupler, which are simultaneously formed. A color image is formed by removing metallic silver (developed silver) and unreacted silver halide generated by the color development and development by bleaching and fixing, respectively. On a color photographic paper, which is a photosensitive material obtained by coating a photosensitive layer having a similar combination of a photosensitive wavelength region and a coloring hue on a reflective support, optical exposure is performed through a color negative film after development processing, By performing the same color development and development, and bleaching and fixing, a color print reproducing the scene at the time of photographing can be obtained.

[0004] Although systems for obtaining such color prints are now widespread, demands for improving their simplicity are increasing. The first reason is that the processing bath for performing the above-described color development / development and bleaching / fixing processing requires precise control of its composition and temperature, and requires specialized knowledge and skilled operations. Is required.
Secondly, the processing solution in the processing bath contains a substance that needs to be regulated for discharge due to environmental problems such as a color developing agent and an iron chelate compound as a bleaching agent. This is because dedicated equipment is often required. Third, although the development process in recent years has been shortened, these development processes require time, and it is still inadequate for the demand for quickly reproducing a recorded image. . Against this background, there is a demand for a color image forming system that does not use the color developing agents and bleaching agents used in existing systems, reduces the burden on the environment, and is excellent in simplicity and speed. Is increasing more and more.

Recently, many improved techniques have been proposed to meet the above demand. For example, IS &T's 48t
h Annual Conference Process
On page 180 of edings, the dye produced by the development reaction was transferred to the mordant layer, and then removed to remove developed silver and unreacted silver halide, which was essential for conventional color photographic processing. A system is disclosed that eliminates the need for a bleach-fix bath. However, in the technology proposed here, development processing with a processing solution containing a color developing agent is still necessary, and it cannot be said that environmental problems have been solved.

As a system that does not require a processing solution containing a color developing agent, Fuji Photo Film Co., Ltd. has provided a pictocolor system. The Pictrocolor system is applied to an application in which a formed dye is fixed to a dye fixing layer and the dye is viewed as a dye image. In this Pictrocolor system, a small amount of water is supplied to a photosensitive material containing a base precursor, which is bonded to an image receiving material, and a development reaction is caused by heating. This is extremely advantageous. Therefore, it is conceivable to solve the above-mentioned problem by applying the Pictocolor system to processing of a recording material for photography. However, when an attempt was made to rapidly form an image by performing heat development using the above-mentioned Pictrocolor system using a high-sensitivity photographic exposure emulsion, a serious problem was found to occur. That is, the emulsion for photography imparted with high sensitivity was a system containing a developing agent, was easily fogged at the time of preservation, and was at a level unsuitable for practical use. It is an essential design requirement for photographic recording materials to maintain high sensitivity and to provide stability during storage, and such problems are reduced while reducing environmental impact. This has been a significant obstacle to simple and fast processing of the material.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A photosensitive silver halide emulsion used in a silver halide color photographic light-sensitive material of the present invention will be described. The photosensitive silver halide emulsion is selected from at least one (one or more) selected from a metal ion and a metal complex ion serving as a shallow electron trap and a metal ion and a metal complex ion serving as a relatively deep electron trap. At least one (one or more). The value of the depth of the electron trap by the metal ion and / or the metal complex ion is, for example, RSEachus, REGrave, MTO
Phys.Stat.Sol (b), vol. 88, p. 705 (197).
It is obtained by kinetic measurement using ESR as disclosed in 8). The depth of the electron trap may vary depending on the type of central metal ion, the type of ligand, the symmetry of the complex point group (Oh, D4h, C4v, etc.), and the halogen composition of the substrate. The depth of the electron trap is determined by whether the energy level of the lowest unoccupied orbit of electrons of the metal ion or metal complex ion is lower or higher than the bottom of the conduction band of silver halide. When the energy level is higher than the bottom of the conduction band of silver halide, the electron is loosely bound by the Coulomb force of the central metal ion, so that the electron becomes a shallow electron trap. The difference corresponds to the depth of the electron trap, resulting in a relatively deep electron trap.

The depth of the shallow electron trap is 0.2 e.
V or less (at most 0.2 eV), and 0.1 e
V or less (at most 0.1 eV) is more preferable. _{Examples of the} metal ion and metal complex ion that can serve as the shallow electron trap include Pb ²⁺ and [M (CN) _{x Ly} N _z ]. In the above formula, M represents Re ⁺ , Os ²⁺ , Ru ²⁺ , F
represents e ²⁺ , Ir ³⁺ or Co ³⁺ . X represents 4, 5 or 6. L and N are halogen ions such as fluorine ion, chlorine ion, bromine ion and iodine ion, SCN ⁻ , NC
Represents an inorganic ligand such as S ⁻ , H ₂ O or the like; or an organic ligand such as pyridine, phenanthroline, imidazole, pyrazole and the like. y and z are numerical values, and their values are determined so as to satisfy x + y + z = 6. Usually, when a ligand is present, the coordination number is six.

The depth of the relatively deep electron trap is:
It is preferably at least 0.35 eV (at least 0.35 eV), more preferably at least 0.5 eV (at least 0.5 eV). The metal ions and metal complex ions that can serve as the relatively deep electron trap include a halogen ion ligand or a thiocyanate ion ligand, Ir,
An ion containing Rh, Ru or Pd; an ion containing at least one nitrosyl ligand and Ru; or

^{_{N) 6] 3-, [RhCl}} 6] 3-, [RhBr 6] 3-,
[PdCl ₆ ] ^{5- and the} like are preferably used.

The introduction of metal ions or metal complex ions into a light-sensitive silver halide emulsion can be achieved by a well-known technique in emulsions of photographic materials using a processing solution containing a conventional developing agent, particularly in tabular emulsions. Yes, JP 8
These are disclosed in, for example, Japanese Patent Application Laid-Open No. 101474, European Patent No. 0699947, and Japanese Patent Application Laid-Open No. H4-211144, and have the effects of increasing sensitivity, improving reciprocity, adjusting sensitivity, and improving stability. However, in a photosensitive material for photographing with a developing agent incorporated therein, such as the silver halide color photographic photosensitive material of the present invention, the metal ion and the metal complex ion, which are the shallow electron traps, and the relatively deep electron trap. It is not known that when used in combination with certain metal ions and metal complex ions, there is an effect that the increase in Dmin can be reduced during storage while maintaining high sensitivity.

Also, JP-A-1-116637, JP-A-2-236542, and JP-A-5-181246.
Gazette, Japanese Patent Application No. 7-122733, U.S. Pat.
JP-A-34043 discloses that in a photothermographic material incorporating a developing agent, Ir is contained in a silver halide emulsion in order to reduce fogging due to heat development, or stability is given to fluctuations in exposure. For this purpose, iron ions may be contained in the silver halide emulsion, or polyvalent metal ions may be contained in the silver halide emulsion for the purpose of lowering the sensitivity and increasing the sensitivity.
And high silver chloride emulsions to enhance contrast even in high illuminance exposure, or to provide high illuminance suitability by incorporating Ir in silver iodobromide in photosensitive materials containing a developing agent such as so-called dry silver. And a method of displacing it.
All of these techniques are aimed at photographic materials for printing and printing, and, like the silver halide color photographic light-sensitive material of the present invention, use a developing agent built-in system to form emulsions by tabular grains. In the case of using a photosensitive material for photography, it is a technique completely different from a technique for achieving high sensitivity and imparting stability during storage, and therefore these techniques are simply applied. However, the object of the present invention is not achieved.

When only metal ions and / or metal complex ions, which are the above-mentioned shallow electron traps, are used, the sensitivity can be increased, but the increase in Dmin during storage due to the incorporation of the developing agent deteriorates. Metal ions and / or metal ions, which are relatively deep electron traps that contribute little to sensitization.
As a result of earnest studies by the inventors of the present invention, it has been found that the use of a metal complex ion together with a metal complex ion can suppress the increase in Dmin during storage caused by the incorporation of a developing agent while increasing the sensitivity.
The metal ions and / or metal complex ions, which are relatively deep electron traps, can suppress an increase in Dmin during storage of a photosensitive material for developing a photographic material with a built-in developing agent, because the developing agent has a higher halogen content over time than the developing agent. Dmin injected into silver halide
It is presumed that the electrons that caused the increase were invalidated.

The amount of the metal ion and / or metal complex ion in the photosensitive silver halide emulsion is about 10 ^-9 to 10 ^-2 mol per mol of silver halide. In the photosensitive silver halide emulsion grains, the metal ions and / or metal complex ions (hereinafter sometimes referred to as “metal ions or the like”) are incorporated into the grains in a uniform state or a localized state. May be incorporated in a state where it is exposed on the surface of the particle, or may be incorporated in a state where it is not exposed on the surface of the particle but localized near the surface. In addition, in the case of epitaxial grains, the crystal may be a base crystal or a crystal at a junction. In the multi-structure type photosensitive silver halide emulsion grains having different phases of the halogen composition, the metal ions to be contained may be changed for each composition. Specifically, for example, it is preferable that the AgCl tabular base particles contain yellow blood salt and that the AgBr crystal containing Ir ions is epitaxially bonded, as described later.
In a fringe-type high-density dislocation-type silver iodobromide emulsion grain having a high silver iodide localization in the vicinity of the surface, the metal ion which is the shallow electron trap and / or the relatively deep electron trap is located at a position where dislocation lines are concentrated. It is also preferable to concentrate the metal ions, etc., which are the relatively deep electron traps on the silver iodobromide crystal base, and to contain the metal ions, etc., which are the shallow electron traps in the epitaxially bonded crystal. Is also preferred. Further, the region may be only a coexisting region of two kinds of metal ions or the like, or may be a region of only the metal ions which are the shallow electron traps and a region of only the metal ions which are the relatively deep electron traps. Or may be composed of the coexistence region and a region of only the metal ions that are the shallow electron traps and / or a region of only the metal ions that are the relatively deep electron traps. A region where no metal ion or the like exists at all may exist in the five.

The metal ions and the like may be added by mixing a metal salt solution of the metal ions or the like with a halide aqueous solution or a water-soluble silver salt solution at the time of grain formation and continuously adding them during grain formation. Silver halide emulsion fine particles doped with metal ions or the like can be added, or a metal salt solution of the metal ions or the like can be directly added before, during, or after grain formation. During particle formation, a solution of a metal salt such as the metal ion may be continuously added.

When the metal salt is dissolved in water or a suitable solvent such as methanol or acetone, an aqueous solution of hydrogen halide (eg, HCl, HBr) is used to stabilize the solution.
Thiocyanic acid or a salt thereof, or an alkali halide (eg, KCl, NaCl, KBr, NaBr)
Etc.) can be used. It is also preferable to add an acid, an alkali or the like as necessary from the viewpoint of stabilizing the solution.

The content of the metal ions and the like in the photosensitive silver halide emulsion is measured, for example, by performing atomic absorption, polarized Zeeman spectroscopy, ICP analysis and the like. Ligands of the metal complex ions, CN ⁻ , SCN ⁻ , NO ⁻
And the like in a photosensitive silver halide emulsion are confirmed by infrared absorption (especially FT-IR).

The halogen composition in the tabular grains of the photosensitive silver halide emulsion usable in the present invention is silver chloride, silver iodochloride, silver chlorobromide, silver iodochlorobromide or silver iodobromide. Can be preferably used. Also, other silver salts, for example, silver thiocyanate, silver sulfide, silver selenide,
Organic silver, such as silver carbonate, silver phosphate, or benzotriazole silver, may be fixed in the halide grains or bonded thereto. The halogen composition may be uniform or may be different between the inside of the grain and the grain surface. In the latter case, the silver halide emulsion grains are grains having a multiple structure or a multilayer structure. Further, silver halide emulsions having different compositions may be joined by epitaxial joining.

Incidentally, high silver chloride emulsions generally have the feature of having high development activity. In addition, since there is little haze, there is also a feature that when the processed photosensitive material is read by a scanner without being fixed, there is little deterioration of image information.

A structure having localized phases having different compositions in a layered or non-layered form inside and / or on the surface of silver halide can also be used. The halogen composition of the localized phase is analyzed by an X-ray diffraction method, an analytical electron microscope, or the like. For example, C.R.Berry, S.J.Marino (CR Ber)

957) describes a method of applying X-ray diffraction to silver halide. The localized phase is located inside the particle or at the edge of the surface,
Although it may be present at the corners or on the surface, a preferred example is one in which the grains are epitaxially bonded at the corners.

As in the case of the present photographic materials, a photosensitive silver halide emulsion mainly composed of silver iodobromide may contain silver chloride. The rate is preferably 8 mol% or less, more preferably 3 mol% or less. In the present invention, silver iodobromide having a laminated structure composed of a plurality of layers having different halogen compositions, and more silver iodide than any of the layer adjacent to the inner side of the grain and the layer adjacent to the surface of the grain. It is preferred to use photosensitive silver halide emulsion grains containing therein grains having at least one layer having a high content of the silver halide emulsion.

When a photosensitive silver halide emulsion composed of silver chlorobromide, silver chloride or the like is used, silver iodide may be contained. In that case, the content of silver iodide is 6 mol%. Or less, more preferably 2 mol% or less. When a high silver chloride emulsion is used, it is disadvantageous in terms of sensitizing dye adsorption. However, dye adsorption can be enhanced by making the surface rich in silver iodide or silver bromide.

The halogen composition on the surface of the photosensitive silver halide emulsion grains is measured by X-ray photoelectron spectroscopy (ESCA).

It is preferable that the halogen composition distribution (silver bromide content, silver iodide content, silver chloride content) between the photosensitive silver halide emulsion grains is narrow. The variation coefficient of the halogen composition distribution is preferably 3 to 30%, more preferably 3 to 25%, and particularly preferably 3 to 20%. The variation coefficient means a value obtained by dividing a variation (standard deviation) by an average. The halogen composition distribution in each photosensitive silver halide emulsion can be determined, for example, by using an X-ray microanalyzer (EP
MA).

The shape of the tabular grains in the photosensitive silver halide emulsion is such that, when the main surface (the outer surface having a large parallel area) is a (111) plane, two or more parallel twin planes are included. When twins are formed and the outer surface consists of (100) planes, no twin planes exist. Twin plane spacing is disclosed in US Pat.
0.01720, as described in US Pat.
2 μm or less.
As described in JP-A-249585, a value obtained by dividing the distance between the (111) main planes by the twin plane spacing can be 15 or more. When the main plane is the (111) plane, the shape of the photosensitive silver halide emulsion grains as viewed from above is triangular, hexagonal, rounded, or elliptical. Even if the main plane is (111),
The side surface connecting the principal planes may be a (111) plane, a (100) plane, a mixture of both, or a plane having a higher index. Good. When the outer surface is the (100) plane, the photosensitive silver halide emulsion grains have a rectangular shape when viewed from above.

In the photosensitive silver halide emulsion used in the present invention, tabular grains preferably occupy 80 to 100%, more preferably 90 to 100%, and 95 to 100% of the total projected area. It is particularly preferred that they occupy.

The average grain thickness of the tabular grains in the photosensitive silver halide emulsion used in the present invention is 0.005 to 0.005.
0.2 μm is preferred, and 0.01 to 0.15 μm is more preferred. The average grain thickness means the arithmetic average of the grain thicknesses of all tabular grains in the photosensitive silver halide emulsion.

The equivalent circle diameter of the average projected area of the tabular grains in the photosensitive silver halide emulsion is preferably from 0.2 to 8 μm, more preferably from 0.3 to 5 μm, and more preferably from 0.4 to 4 μm.
μm is particularly preferred.

The ratio of the circle-equivalent diameter to the average thickness of the tabular grains in the photosensitive silver halide emulsion is called an aspect ratio. The average aspect ratio of the tabular photosensitive silver halide emulsion grains in the present invention is from 4 to 10
0 is preferable, and 6 to 80 is more preferable. When the average aspect ratio is less than 4, it is disadvantageous in terms of sensitivity,
If it exceeds 100, the pressure properties are poor and the particle size distribution tends to be polydisperse, which is not preferable. The average aspect ratio means the arithmetic average of the average aspect ratios of all tabular grains in the photosensitive silver halide emulsion.

When the projection surface of the tabular grains in the photosensitive silver halide emulsion has a hexagonal shape, all tabular grains having a ratio of the maximum length to the minimum length of 1 to 2 are required. It preferably occupies 50 to 100% of the projected area of the grain, more preferably 70 to 100%. The ratio is preferably hexagonal tabular grains close to 1. When the projection surface of the tabular grains in the photosensitive silver halide emulsion is rectangular, tabular grains having a maximum length side length ratio of 1 to 2 with respect to a minimum length side length are projected from all grains. It preferably occupies 50 to 100% of the area, more preferably 70 to 100%. The ratio is preferably a square tabular grain close to 1.

The shape of the photosensitive silver halide emulsion grains is determined by a carbon replica method in which the photosensitive silver halide emulsion grains and a reference latex sphere used as a size standard are simultaneously shadowed with a heavy metal or the like. It can be measured by observation with a transmission electron microscope.

It is preferred to use a monodispersed photosensitive silver halide emulsion having a narrow grain size distribution. The monodispersed light-sensitive silver halide emulsion means one having a variation coefficient of grain size distribution of 30% or less. The use of the monodispersed light-sensitive silver halide emulsion is described in Surfer Science Series (Technical Applications of Dispersions) by Trevor Matanahan.
rfactant Science Series) 5
2, p. 373 (1994). Further, a polydispersed photosensitive silver halide emulsion having a wide grain size distribution may be used. In addition, as disclosed in JP-A-1-167743 and JP-A-4-223463, two or more types of monodisperse particles having substantially the same color sensitivity and different particle sizes are used for adjusting the gradation. A photosensitive silver halide emulsion may be used in combination. Two or more monodispersed photosensitive silver halide emulsions may be mixed in the same layer or may constitute separate layers. Two or more polydisperse photosensitive silver halide emulsions or a combination of a monodisperse photosensitive silver halide emulsion and a polydisperse photosensitive silver halide emulsion can also be used.

A method for preparing tabular grains using silver bromide, silver (iodo) bromide, and silver (salt) silver bromide comprising the (111) plane is described in JP-A-55-142329 and JP-A-58-113926. Nos. 58-113927 and 58-11392.

Tabular grain forming methods using the polyalkyl oxide compounds described in the specifications of JP-A-52110013 and JP-A-5252453 are preferred. In order to form tabular grains in a photosensitive silver halide emulsion having a high average aspect ratio, it is important to form twin nuclei having a small size. For this purpose, low temperature, high pBr and low pH are used, the amount of gelatin is reduced, and methionine with a low or low molecular weight or a phthalated gelatin derivative is used. It is preferred to carry out the formation. After nucleation, by physical ripening, only tabular grain nuclei (parallel multiple twin nuclei) are grown, and other normal crystal nuclei, single twin nuclei, and non-parallel multiple twin nuclei are eliminated and selectively parallelized. Form multiple twin nuclei. Thereafter, a soluble silver salt and a soluble halide salt, or a small-sized silver halide fine grain emulsion was added,
Grain growth is performed to prepare a photosensitive silver halide emulsion containing tabular grains.

Tabular grains composed of a high silver chloride emulsion composed of (111) planes are described in US Pat.
These are described in JP-A-400463, JP-A-5217858, JP-A-2-32 and the like. In the case of high silver chloride, since the (100) plane is usually the outer surface under the condition where there is no adsorbed substance, the adsorbed substance having plane selectivity is used for the (111) plane and twin nuclei are formed. In the physical ripening process, normal crystal nuclei, single twin nuclei, and non-parallel multiple twin nuclei are eliminated to selectively obtain parallel multiple twin nuclei, and then the grains are grown to form tabular grains. A light-sensitive silver halide emulsion is prepared.

The empirical rule for forming silver chloride tabular grains composed of (111) planes is described in Journal of Photographic Science.

The point is the generation of nuclei that grow in a plate shape, and it is effective to add bromide ions or iodide ions in the early stage of grain formation, or to add a compound exhibiting selective adsorption to a specific surface. .

The grain growth is carried out by adding a soluble silver salt and a soluble halide salt, or a small-sized silver halide fine grain emulsion.

Such tabular grains have a larger surface area than normal crystals of the same volume, so that the amount of sensitizing dye adsorbed can be increased, which is advantageous in terms of color sensitization sensitivity. Therefore, since the volume of the particles can be reduced at the same sensitivity as compared with the normal crystal grains, the number of development start points increases with an increase in the number of particles, and the graininess, which is a critical performance in a photographic material for photography, is excellent. In addition, since the granularity is advantageous, the amount of coated silver can be reduced, which is excellent in suppressing radiation fog which is a problem of a photosensitive material for high-sensitivity photography. The reduction in the amount of coated silver is effective in reducing the haze that causes deterioration of image information when the processed photosensitive material is read by a scanner without being fixed, as described later. Since tabular grains have a large specific surface area, they have the feature of having high development activity. Further, since the tabular grains are aligned and aligned at the time of coating, the photosensitive material can be made thinner, and the sharpness is excellent.
As described above, tabular grains are essential emulsion grains in a photographic material for photography. As long as the pressure property and the monodispersibility of the particle distribution are not impaired, it is preferable that the average aspect ratio of the tabular grains is large in terms of sensitivity, granularity, activity, reduction of the amount of coated silver, and the like.

The tabular grains in the photosensitive silver halide emulsion used in the present invention may have dislocation lines. The dislocation line is a linear lattice defect at a boundary between a region that has already slipped and a region that has not yet slipped on the slip surface of the crystal.

72), etc., which can be analyzed by an X-ray diffraction method or a direct observation method using a low-temperature transmission electron microscope.

When the dislocation lines are directly observed using a transmission electron microscope, the photosensitive silver halide emulsion grains should be kept under pressure not to generate the dislocation lines. The silver halide grains taken out from the emulsion grains are placed on a mesh for observation with an electron microscope, and the sample can be observed by a transmission method in a cooled state so as to prevent damage (for example, printout) by an electron beam.
In this case, the thicker the photosensitive silver halide emulsion grains, the more difficult it is for an electron beam to pass therethrough.
The use of an electron microscope (200 kV or more with respect to a thickness of m) enables more clear observation.

JP-A-63-220238 discloses a technique for introducing dislocation lines into silver halide grains while controlling the dislocation lines. It is shown that the tabular grains into which the dislocation lines are introduced have excellent photographic characteristics such as sensitivity and reciprocity law as compared with the tabular grains without the dislocation lines.

In the case of tabular grains, the position and the number of dislocation lines of each grain as viewed from the direction perpendicular to the main plane are determined from the photograph of the grains taken with an electron microscope as described above. Can be.

When the tabular grains in the light-sensitive silver halide emulsion used in the present invention have dislocation lines, their positions are limited to, for example, the apexes and fringe portions of the grains, or are introduced over the entire main plane portion. Any of these can be appropriately selected from among them, but it is particularly preferable to limit to the fringe portion.

In the present invention, the fringe portion means the outer periphery of the tabular grains. More specifically, the distribution of silver iodide from the sides to the center of the tabular grains is the first point when viewed from the side. Is outside the point where the content of silver iodide exceeds or falls below the average silver iodide content of the whole grain.

In the present invention, when the tabular grains have dislocation lines, the density of the dislocation lines is arbitrary, and can be appropriately selected depending on the case, such as 10 or more, 30 or more, or 50 or more per grain. .

The photosensitive silver halide emulsion containing tabular grains and the silver halide emulsion other than that of the present invention used together therewith in the present invention are described below. In the following description, both emulsions are sometimes collectively referred to as "silver halide emulsion" for convenience.

The surface may be the inside, the inside, or an extremely shallow inside (shallow inner surface). The method for preparing the silver halide emulsion may be any of an acidic method, a neutral method and an ammonia method. The pH may be as high as possible without causing fogging.
As a method of reacting the soluble silver salt with the soluble halogen salt, a one-sided mixing method, a simultaneous mixing method, or a combination thereof can be used. A method of forming grains in a state where silver ions are excessive (so-called reverse mixing method) can also be used. As one type of the double jet method, a method in which pAg in a liquid layer in which silver halide is formed is kept constant, that is, a so-called controlled double jet method can be used. According to this method, a silver halide emulsion having a regular crystal system and a nearly uniform grain size distribution and halogen composition can be obtained. Also, as described in U.S. Pat. No. 4,879,208, it is preferable to add an ultrafine grain emulsion prepared in situ during emulsion preparation to an emulsion preparation tank and then grow the grains by physical ripening. This ultrafine particle emulsion may be prepared in advance.

In the process of preparing a photosensitive silver halide emulsion according to the present invention, it is preferable to carry out a desalting step for removing excess salts. A Nudel washing method performed by gelling gelatin may be used, and inorganic salts composed of polyvalent anions (eg, sodium sulfate), anionic surfactants, anionic polymers (eg, sodium polystyrene sulfonate), A sedimentation method (flocculation) using a gelatin derivative (aliphatic acylated gelatin, aromatic acylated gelatin, aromatic carbamoylated gelatin, etc.) may be used.

The ultrafiltration apparatus described in the specification may be used, or a natural sedimentation method or a centrifugal separation method may be used. Normally,
The sedimentation method is preferably used.

The photosensitive silver halide emulsion of the present invention can be used without chemical sensitization, but is usually used after chemical sensitization. The chemical sensitization method used in the present invention includes:
Sulfur sensitization, selenium sensitization, chalcogen sensitization such as tellurium sensitization, noble metal sensitization using gold, platinum, palladium and the like, and reduction sensitization can be used alone or in combination (for example, JP-A-3-110555 and Japanese Patent Application No. 4-75798. These chemical sensitizations can be carried out in the presence of a nitrogen-containing heterocyclic compound (JP-A-62-253159). Further, an anti-fogging agent described later can be added after the completion of chemical sensitization. Specifically, JP-A-5-45833, JP-A-62-404
The method described in JP-A-46-46 can be used.

These chemical sensitizations can be carried out in any step of the process for producing a photosensitive silver halide emulsion. Various types of emulsions can be prepared depending on the step of chemical sensitization. There are a type in which a chemical sensitizing nucleus is embedded inside the grain, a type in which the chemical sensitizing nucleus is embedded in a position shallow from the surface of the grain, and a type in which a chemical sensitizing nucleus is formed in the surface of the grain. Various chemical sensitization nuclei can be formed inside or on the surface of the grain or at a position shallow from the surface of the grain. For example, it is preferable to form a reduction sensitizing nucleus inside a grain and a chalcogen sensitizing nucleus and / or a gold chalcogen sensitizing nucleus on the surface of the grain, but various combinations are possible depending on the purpose.

As the sulfur sensitizer, an unstable sulfur compound is used, and specifically, thiosulfate (eg, hypo),
Known sulfur compounds such as thioureas (for example, diphenylthiourea, triethylthiourea, allylthiourea, etc.), allyl isothiocyanate, cystine, p-toluenethiosulfonate, rhodanines, and mercaptos can be used. The addition amount of the sulfur sensitizer may be an amount sufficient to effectively increase the sensitivity of the emulsion.

As a guide, 10 ^-9 per mole of the photosensitive silver halide emulsion is used.
It is preferred to use from 10 to 10 ^-1 mol.

In the selenium sensitization, a known unstable selenium compound is used. Specifically, colloidal metal selenium, selenoureas (eg, N, N-dimethylselenourea, N, N-diethylselenourea, etc.) ), Selenoketones, selenoamides, aliphatic isoselenocyanates (eg, allyl isoselenocyanate), selenocarboxylic acids and esters, selenophosphates, diethyl selenides, diethyl diselenides, and other selenides. Can be used. The addition amount varies depending on various conditions as in the case of the sulfur sensitizer, but as a guide, it is preferable to use 10 ^-10 to 10 ^-1 mol per mol of the photosensitive silver halide emulsion.

In the present invention, in addition to the above-described chalcogen sensitization, sensitization with a noble metal can also be performed. First, in gold sensitization, the valence of gold may be +1 or +3, and various gold compounds are used. Representative examples include chloroauric acids, potassium chloroaurate, auric trichloride, potassium aurithiocyanate, potassium iodooleate, tetraauric acid, ammonium aurothiocyanate, pyridyl trichlorogold,
Gold sulfide, gold selenide, gold telluride and the like. Although the amount of the gold sensitizer to be added varies depending on various conditions, it is preferably used in a range of 10 ^-10 to 10 ^-1 mol per mol of silver halide. When to add the gold sensitizer,
At the same time as sulfur sensitization or selenium sensitization, tellurium sensitization,
It may be during, before, or after the sulfur sensitization, selenium sensitization, or tellurium sensitization step, or the gold sensitizer may be used alone. PAg, pH of emulsions subjected to sulfur sensitization, selenium sensitization, tellurium sensitization or gold sensitization in the present invention
The pAg is 5 to 11 and the pH is 3 to 1
The pAg is preferably used in the range of 0 to 6.8.
More preferably, it is used in the range of 9.0 and pH 5.5 to 8.5.

In the present invention, noble metals other than gold can be used as the chemical sensitizer. As a noble metal other than gold, for example, a sensitizer based on a metal salt such as platinum, palladium, iridium, and rhodium or a complex salt thereof can be used.
As the palladium compound, a divalent or tetravalent palladium salt can be used. For example, K ₂ PdCl ₄ , Na ₂ PdCl _{6 and the} like are preferable. Gold and noble metal compounds may be used in combination with thiocyanates or selenocyanates.

In the present invention, reduction sensitization can be further performed. The reduction sensitization is preferably performed during grain formation, after grain formation, and before or during chemical sensitization, or after chemical sensitization. Here, the reduction sensitization is

The alkynylamine compounds described in the specification of JP-A-9,510 are also effective compounds. Since the addition amount of the reduction sensitizer depends on the emulsion conditions, it is necessary to select the addition amount, but an appropriate range is 10 ^-9 to 10 ^-2 mol per mol of silver halide. In addition to the method of adding the reduction sensitizer, or through the passage of hydrogen gas, by the nascent hydrogen by electrolysis,
A method of reduction sensitization can also be selected. The reduction sensitization can be used alone or in combination with the chalcogen sensitization or the noble metal sensitization.

The reduction sensitizer is dissolved in water or a solvent such as alcohols, glycols, ketones, esters and amides and added during and / or after grain formation. When it is added during the formation of the particles, it may be added to the reaction vessel in advance, but it is more preferable to add it at an appropriate time during the formation of the particles. Alternatively, a reduction sensitizer may be added to an aqueous halide solution or a water-soluble silver salt solution, and these solutions may be used to precipitate photosensitive silver halide emulsion grains. In addition, the solution of the reduction sensitizer may be added in several portions as the grains grow, or it may be preferably added continuously for a long time.

It is preferable to use an oxidizing agent for silver during the production process of the photosensitive silver halide emulsion of the present invention. The oxidizing agent for silver refers to a compound having an action of converting metallic silver into silver ions. In particular, a compound that converts extremely fine silver particles by-produced in the process of forming photosensitive silver halide emulsion grains and in the process of chemical sensitization into silver ions is effective. The silver ion generated here may form a silver salt which is hardly soluble in water such as silver halide, silver sulfide, silver selenide, or a silver salt which is easily soluble in water such as silver nitrate. Is also good. The oxidizing agent for silver may be an inorganic substance or an organic substance.

The disulfide compound described in 57A2 is also a preferred compound. It is a preferred embodiment to use the above-described reduction sensitization in combination with an oxidizing agent for silver. After using the oxidizing agent, the method can be selected from a method of performing reduction sensitization, a reverse method, or a method of coexisting both. These methods can be selectively used in both the grain formation step and the chemical sensitization step.

Along with the sensitizing dye, the emulsion may contain a dye which does not itself have a spectral sensitizing effect or a substance which does not substantially absorb visible light and exhibits supersensitization. The sensitizing dye may be added to the emulsion at any stage in the preparation of the emulsion which has been known to be useful. Most commonly, this is done after completion of chemical sensitization but before coating, but US Pat. No. 3,628,969.
As described in JP-A-58-1139 and JP-A-4225666, spectral sensitization can be carried out simultaneously with chemical sensitization by simultaneous addition with a chemical sensitizer.
It can be carried out prior to chemical sensitization as described in JP-A-28, or it can be added before the completion of precipitation of silver halide grains to start spectral sensitization. Furthermore, as taught in U.S. Pat.

In the present invention, as a coupler, a 4-equivalent coupler and a 2-equivalent coupler can be selectively used depending on the type of the developing agent. First, a 4-equivalent coupler is used for the developing agent represented by the general formula (I). In the developing agent of the general formula (I), the coupling site is substituted by a sulfonyl group, and at the time of coupling, the sulfonyl group is released as sulfinic acid, so that the leaving group on the coupler side must be released as a cation. . Therefore, it reacts with a 4-equivalent coupler capable of releasing a proton as a leaving group during coupling, but does not react with a 2-equivalent coupler whose leaving group is an anion. vice versa,
2 for the developing agents represented by formulas (II) and (III)
Use an equivalent coupler. In the developing agents represented by the general formulas (II) and (III), the coupling site is substituted by a carbamoyl group, and the hydrogen atom on the nitrogen atom is released as a proton during the coupling. Must be eliminated as an anion. Therefore, it reacts with a 2-equivalent coupler capable of releasing an anion as a leaving group during coupling, but does not react with a 4-equivalent coupler whose leaving group is a proton. By using this combination, it is possible to prevent color turbidity due to interlayer movement of the oxidized form of the developing agent. Specific examples of the coupler include a 4-equivalent coupler and a 2-equivalent coupler, both of which can be found in Theory of the Photographic Process (edited by 4th Ed.

In the present invention, the scene at the time of shooting is recorded,
In order to construct a silver halide color photographic light-sensitive material used for reproducing a color image, the principle of color reproduction by a subtractive color method can be basically used. That is, at least three types of photosensitive layers having photosensitivity are provided in the blue, green, and red regions, and yellow, magenta, and cyan dyes are formed in each of the photosensitive layers, which are complementary colors to the photosensitive wavelength region. The color information of the original scene can be recorded by including a color coupler which can be used. By exposing a color printing paper having a similar relationship between the photosensitive wavelength and the color hue through the dye image obtained in this way, the scene at the time of shooting can be reproduced. Further, information of a dye image based on a scene at the time of shooting can be read by a scanner or the like, and an image for viewing can be reproduced based on this information.

As the silver halide color photographic light-sensitive material of the present invention, a light-sensitive layer having photosensitivity in three or more wavelength regions can be provided. It is also possible to provide a relationship other than the above-described complementary colors between the photosensitive wavelength region and the color hue. In such a case, after fetching the image information as described above, by performing image processing such as hue conversion, it is possible to reproduce the color information of the scene at the time of shooting.

In the present invention, it is preferable to include at least two types of photosensitive silver halide emulsions having a sensitivity in the same wavelength region and different average grain projected areas. Having photosensitive in the same wavelength region as referred to in the present invention means having photosensitive in the same wavelength region effectively. Therefore, even when the photosensitive silver halide emulsions whose spectral sensitivity distributions are slightly different from each other are used, if the main photosensitive areas overlap, this means that the photosensitive silver halide emulsions have sensitivity in the same wavelength region. .

In the present invention, in order to include a plurality of photosensitive silver halide emulsions having sensitivity to these same wavelength regions and different average grain projected areas, separate photosensitive silver halide emulsions are required for each of the photosensitive silver halide emulsions. A photosensitive layer may be provided, or one photosensitive layer may contain a mixture of a plurality of the above-described photosensitive silver halide emulsions. When these light-sensitive silver halide emulsions are contained in separate light-sensitive layers, it is preferable to use color couplers having the same hue, but it is preferable to use couplers having different hues. It is also possible to use different coloring hues for the respective photosensitive layers, and to use couplers having different absorption profiles of the coloring hues for the respective photosensitive layers.

In the present invention, when coating a photosensitive silver halide emulsion having photosensitivity in these same wavelength regions, these photosensitive silver halide emulsions are coated in a unit area of a silver halide color photographic light-sensitive material. The ratio of the number of silver halide grains of the emulsion having a larger average grain projected area is such that the coated silver amount of the photosensitive silver halide emulsion is 3 / (the average grain projected area of the photosensitive silver halide emulsion grains contained in the emulsion). It is necessary to configure so as to be larger than the ratio of the value divided by the square. By adopting such a configuration, an image having good granularity can be obtained even under development conditions heated to high temperature. In addition, high developability and a wide exposure latitude can be satisfied at the same time.

Conventionally, in a color negative film which has been used for photography, not only the improvement of the photosensitive silver halide emulsion to achieve the desired granularity, but also the coupling reaction with the oxidized form of the developing agent is required. Techniques such as using a so-called DIR coupler that releases a development inhibiting compound have been used. In the silver halide color photographic light-sensitive material of the present invention, excellent granularity can be obtained even when no DIR coupler is used. In addition, the combination of DIR compounds results in increasingly better granularity.

Dyes which can be used in the yellow filter layer and the antihalation layer are preferably those which are decolored or eluted during development and do not contribute to the density after processing. The fact that the dye in the yellow filter layer and the antihalation layer is erased or removed at the time of development means that the amount of the dye remaining after the processing is 1/3 or less, preferably 1 /
The dye component may be eluted from the light-sensitive material at the time of development or may be transferred to the processing material during development, or may be converted to a colorless compound upon reaction during development.

For example, a dye that dissolves in the alkali of the developer, a component in the developer, a sulfite ion, a developing agent, or a dye that reacts with the alkali to erase the color can be used. Specific examples include the dyes described in European Patent Application EP549,489A and the dyes ExF2 to Ex6 described in JP-A-7-152129. Japanese Patent Application No. 6-2598

The silver halide color photographic light-sensitive material of the present invention may have a form having a conductive heating element layer as a heating means for heat development. As the heat-generating elements, those described in JP-A-61-145544 can be used.

In the present invention, image information can be taken in without removing developed silver and undeveloped photosensitive silver halide generated by development, but an image can be taken after removal. In the latter case, a means for removing them at the same time as or after the development can be applied. In order to remove the developed silver in the silver halide color photographic light-sensitive material at the same time as the development and to complex or solubilize the light-sensitive silver halide, a silver oxidizing agent acting as a bleaching agent for the processing material or rehalogenation An agent or a silver halide solvent acting as a fixing agent may be contained so as to cause these reactions during thermal development. After the development of the image formation is completed, a second material containing a silver oxidizing agent, a rehalogenating agent or a silver halide solvent is bonded to a silver halide color photographic light-sensitive material to remove developed silver or to remove a photosensitive halogen. It can also cause complexation or solubilization of silver halide. In the present invention, it is preferable to carry out these processes to the extent that image information is not obstructed after photographing and subsequent image formation and development. In particular, undeveloped photosensitive silver halide causes high haze in the gelatin film and increases the background density of the image, so that the haze is reduced or solubilized by using the complexing agent as described above. It is preferable to remove all or part of the film from the film. It is also preferable to use tabular grains having a high average aspect ratio or tabular grains having a high silver chloride content in order to reduce the haze of the photosensitive silver halide itself. Tabular grains having a high average aspect ratio have a large decrease in haze due to a reduction in the amount of coated silver.

The second processing was performed as follows.
That is, after applying 10 ml / m ² of water to the surface of the treatment layer (first to fourth layers) of the second treatment material P-2, the surface of the treatment layer and the sample 101 after the first treatment were performed. To 104, and heat-developed at 60 ° C. for 30 seconds. After the second treatment, the transmission density of each sample was measured to obtain a so-called characteristic curve. 0.1 than fog density
5 The relative sensitivity is defined as the reciprocal of the exposure amount corresponding to the higher density.
The sensitivity of 104 was expressed as a relative value of the sensitivity of Sample 101. In addition, forced storage conditions (60 ° C, 40% relative humidity)
After 5 days, the same exposure and processing as described above were performed.
Table 5 shows the results of sensitivity Dmin immediately after application and increase ΔDmin of sensitivity Dmin after forced storage conditions.

[0209]

[Table 5]

With respect to the photosensitive material containing no developing agent (samples 101A to 104A), the sample immediately after application and the sample after the same forced storage conditions were subjected to the same exposure as described above to obtain a conventional color developing agent. Was processed at 38 ° C. for 165 seconds using a processing bath containing (a color-negative film processing CN-16). Table 6 shows the results.

[0211]

[Table 6]

From the results shown in Table 5, it can be seen that the photosensitivity including tabular grains formed by using a metal ion and / or metal complex ion as a shallow electron trap and a metal ion and / or metal complex ion as a deep electron trap in combination. With the silver halide color photographic light-sensitive material of the present invention (sample 104), which uses a silver halide emulsion and develops with a built-in developing agent,
It is evident that high feeling and stability, in particular, an increase in fogging over time can be suppressed. On the other hand, from the results in Table 6, the photosensitive materials having no built-in developing agent (samples 101A to 104A)
, The results are generally poorer than those of a photosensitive material containing a developing agent. In particular, in Sample 104A, the effect of the photosensitive silver halide emulsion used in the present invention reduces the fogging during storage, It can be seen that a dramatic and excellent effect cannot be obtained as in a silver halide color photographic light-sensitive material containing a developing agent (sample 104).

Also, in the silver halide color photographic light-sensitive materials containing a developing agent (samples 101 to 104), like the samples 101A to 104A, the samples immediately after coating and the samples after the same forced storage conditions as described above were used. Exposure was performed, and processing was performed at 38 ° C. for 165 seconds using the processing bath (processing CN-16 for color negative film). As a result, ΔDmin
Was almost the same as in the case of heat development of a silver halide color photographic light-sensitive material containing a developing agent, except that the absolute value was reduced by about 2/3. Samples 101 to 104 and Sample 1
The sensitivity changes after the forced storage conditions of 01A to 104A are as follows:
It was not a problem. As described above, when only the metal ions and / or metal complex ions, which are shallow electron traps, are used, the sensitivity is increased, but the increase in Dmin after the forced storage conditions is deteriorated (sample 103). On the other hand, when using only metal ions and / or metal complex ions which are deep electron traps,
In increase is suppressed, but it cannot be sensitized (sample 10
2). However, as in the present invention, a photosensitive silver halide emulsion comprising a combination of a metal ion and / or metal complex ion as a shallow electron trap and a metal ion and / or metal complex ion as a deep electron trap is used. If there was, after the forced storage conditions derived from the built-in developing agent
It can be seen that it is extremely effective in suppressing an increase in Dmin (sample 104).

[Table 10]

From the results in Table 10, it can be seen that even in the tabular high-silver chloride emulsion, there is an increase in fog over time due to the built-in developing agent, and the high-silver chloride-based emulsion has high activity. It is apparent from the comparison with the sample 101 in Example 1 that the extent of the increase in fogging is more severe than that of the silver iodobromide emulsion. However, by using a metal ion and / or metal complex ion that is a shallow electron trap and a metal ion and / or metal complex ion that is a deep electron trap in combination, it is possible to obtain a high silver chloride emulsion while maintaining high sensitivity. It can be seen that the increase in Dmin due to the developing agent contained therein can be extremely effectively suppressed. It is clear that this effect is also remarkable in an epitaxial tabular high silver chloride emulsion formed by epitaxial junction grains.
