Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a silver halide color photographic light-sensitive material.

More particularly, it relates to a silver halide photographic light-sensitive material having high sensitivity and small processing fluctuation.

[0003]

2. Description of the Related Art In recent years, the demand for silver halide color photographic light-sensitive materials, especially color light-sensitive materials for photography, has become more and more strict, and high sensitivity, excellent graininess and sharpness have been obtained, and when the light-sensitive materials are continuously developed. There is a demand for a light-sensitive material with a small variation.

JP-A-63-220238 and JP-A-1-201649 disclose tabular silver halide grains into which dislocation lines (certain linear lattice defects existing in crystals) are intentionally introduced. It has been shown that tabular grains containing dislocation lines are superior in photographic characteristics such as sensitivity and reciprocity law to tabular grains having no dislocation lines, and that when they are used in a light-sensitive material, they are superior in sharpness and graininess. . Further, JP-A-5-341459 discloses that a tabular silver halide grain having 10 or more dislocation lines per grain on the outer periphery of the grain provides high sensitivity and improved graininess, gradation and fog. It has been shown that an emulsion is obtained. The tabular grains having dislocations introduced in this way have high sensitivity,
It has favorable qualities for improving image quality. But,
Regarding the further improvement of sensitivity and image quality, there is still a lot of room for research on the number of dislocation lines and their location. On the other hand, there are strong demands for the phenomenon and fixing of silver halide photographic light-sensitive materials. A long processing time for development and fixing is a drawback of silver halide photography, and there is a strong need for speeding up processing.
In addition, it is desirable to reduce the treatment waste liquid or reduce it to zero in order to reduce the influence on the environment. In that case, the amount of the photographic material eluate having a development suppressing action accumulated in the processing liquid increases, which can prevent the shortening of the processing time and increase the fluctuation range of the sensitivity due to the processing. It has been found that the influence of development suppression by the eluate of the light-sensitive material is great in the emulsion containing tabular silver halide grains having a large grain surface area. Therefore, it is extremely important to reduce the range of processing fluctuation, which is a practical defect of tabular grains, and bring out the merits originally possessed by tabular grains in terms of improvement in sensitivity and image quality.

[0005]

An object of the present invention is to use an emulsion containing tabular silver halide grains to obtain a silver halide color having low fog, high sensitivity, high image quality, and small processing fluctuation. It is to provide a photographic material.

[0006]

[Means for Solving the Problems] The above-mentioned object is as follows (1)
It was achieved by means of (2). (1) At least two layers of red-sensitive emulsion layers having different sensitivities, at least two layers of green-sensitive emulsion layers having different sensitivities, and at least two layers of blue-sensitive emulsion layers on a support. In a silver halide color photographic light-sensitive material, the highest-sensitivity layer of the red-light-sensitive emulsion layer, the highest-sensitivity layer of the green-light-sensitive emulsion layer and the highest-sensitivity layer of the blue-light-sensitive emulsion layer. In the halogenated emulsion, tabular silver halide grains having an aspect ratio of 2 to 40 and having a dislocation line in the outer peripheral portion are 100% of the projected area of all the halogenated grains in each of the halogenated emulsions. Through 60
%, And each of the halogenated emulsions is selenium sensitized, a silver halide color photographic light-sensitive material. (2) The silver halide color photographic light-sensitive material according to (1), which has a magnetic recording layer containing magnetic particles on the opposite side of the support of the photosensitive emulsion layer.

Hereinafter, the present invention will be described in detail. The silver halide color photographic light-sensitive material of the present invention (hereinafter referred to as "light-sensitive material")
Also referred to as), on the support, at least two layers of red-sensitive emulsion layers having different sensitivities, at least two layers of green-sensitive emulsion layers having different sensitivities, and at least two layers of blue-sensitive emulsion layers having different sensitivities. You must first have the layers. The arrangement form thereof is not particularly limited, but a specific mode will be described later. Next, in the light-sensitive material of the present invention, the highest-sensitivity layer of the red light-sensitive emulsion layer, the highest-sensitivity layer of the green light-sensitive emulsion layer and the highest-sensitivity layer of the blue light-sensitive emulsion layer are included. It is further necessary for each of the silver halide emulsions described above that the silver halide tabular grains satisfying the two specific requirements account for 100 to 60% of the projected area of all the silver halide grains in each of the halide emulsions. The first of the above specific requirements for the silver halide tabular grains is that the aspect ratio is 2 to 40. In the present invention, a silver halide tabular grain having an aspect ratio (that is, "corresponding to a circle equivalent diameter of a silver halide grain / grain thickness") of 2 to 40 is a halogenated emulsion containing it (of each highest sensitivity layer). It is preferable that 100 to 70% (area) of all silver halide grains of (emulsion) are present.

More preferably, the aspect ratio is 4 to 30.
Of 100 to 80% (area), and particularly preferably 100 to 80% (area) of particles having an aspect ratio of 5 to 25 are present. If the aspect ratio is less than 2, the advantage of tabular grains (that is, contribution to sensitivity and image quality improvement) cannot be fully utilized, which is not preferable. When it is more than 40, the pressure property is deteriorated, which is not preferable. When tabular grains having an aspect ratio of 2 to 40 are less than 60% (area), it is not preferable in terms of homogeneity between grains. As an example of the method of measuring the aspect ratio, there is a method of taking a transmission electron microscope photograph by the replica method and obtaining the equivalent circle diameter and thickness of the projected area of each particle. In this case, the thickness is calculated from the length of the shadow of the replica. The "tabular grain" in the present invention is a silver halide grain having two parallel main planes facing each other. The tabular grains of the present invention have one twin plane or two or more parallel twin planes.

The twin plane means the (111) plane when ions at all lattice points on both sides of the (111) plane have a mirror image relationship. When viewed from above, the tabular grains have a triangular shape, a hexagonal shape, or a rounded circular shape, and have outer surfaces parallel to each other.

In the present invention, hexagonal tabular grains having a ratio of the length of the side having the maximum length to the length of the side having the minimum length of 2 to 1 are projections of all grains in the emulsion. It is preferable to occupy 100 to 50% of the area, more preferably 100 to 70%, particularly preferably 100 to 90%.
Account for%.

The emulsion in the present invention is preferably monodisperse. In the present invention, the variation coefficient of the grain size distribution of all silver halide grains is preferably 25% to 3%, more preferably 15% to 3%, particularly preferably 10% to 3%. The coefficient of variation of the particle size distribution is a value obtained by dividing the standard deviation of the particle size distribution of the particles by the average particle size.

The second specific requirement of the silver halide tabular grain is that it has a dislocation line on the outer periphery (in the present specification, a tabular grain having a dislocation line on the outer periphery is referred to as a fringe portion dislocation type tabular grain). Also called). Specifically, the dislocation line is a linear lattice defect at the boundary between the already slipped region and the non-slip region on the slip plane of the crystal.

When directly observing dislocation lines using a transmission electron microscope, be careful not to apply pressure to the grains to generate dislocation lines, put the silver halide grains taken out from the emulsion on a mesh for electron microscope observation, The sample is observed by a transmission method in a cooled state so as to prevent damage (for example, printout) due to an electron beam. In this case, the thicker the particles, the more difficult it is for an electron beam to pass therethrough. Therefore, it is possible to more clearly observe using a high-voltage electron microscope (200 kV or more for a thickness of 0.25 μm). In the case of tabular grains, the position and the number of dislocation lines for each grain when viewed from the direction perpendicular to the principal plane can be determined from the photograph of the grain taken by using an electron microscope as described above. Depending on the tilt angle of the sample with respect to the electron beam, dislocation lines may or may not be seen.Therefore, in order to observe dislocation lines without omission, dislocation lines of the same grain should be observed by observing particle photographs at as many sample tilt angles as possible. It is necessary to find the location.

In the present invention, it is preferable to determine the existence position and the number of dislocation lines by using a high-voltage electron microscope and changing the tilt angle in steps of 5 ° with respect to the same grain to photograph five types of grain. . When dislocation lines are densely present, or when dislocation lines are observed intersecting with each other, the number of dislocation lines per grain may not be clearly counted. However, even in these cases, the number can be counted to about 10, 20, 30, and so on. The "tabular grain having a dislocation line on the outer periphery of the grain" in the present invention is a grain having at least one dislocation line on the outer periphery of the grain. High-density dislocation-type particles having 10 or more dislocation lines, more preferably 50 or more dislocation lines, and particularly preferably 100 or more dislocation lines on the periphery of the grain. It is preferable that the dislocation line is substantially localized on the outer peripheral portion of the grain. The "outer peripheral portion of the grain" as used in the present invention is the average silver iodide content of the entire grain when the silver iodide content at the point when it is first seen from the side in the distribution of silver iodide from the side to the center of the tabular grain. The point outside the point where the content exceeds or falls below. In the present invention, the silver halide tabular grain having a dislocation line on the outer periphery of the grain is 100 to 60 of all the silver halide grains of the halogenated emulsion containing it (the emulsion of each highest sensitive layer).
% (Area) must be present as described above,
It is preferably present from 100 to 70%.

Further, in the light-sensitive material of the present invention, the highest-sensitivity layer of the red-sensitive emulsion layer, the highest-sensitivity layer of the green-sensitive emulsion layer and the highest-sensitivity layer of the blue-sensitive emulsion layer are respectively formed. The halogenated emulsion contained must be selenium sensitized. The selenium sensitization that can be used for that purpose will be described. Regarding the selenium sensitization method, US Pat.

The following are emulsions used in the present invention (that is, included in the highest sensitive layer of each light-sensitive layer in the present invention,
Emulsions defined as satisfying predetermined requirements, and emulsions usable in other layers). Thus, where the following description conflicts with a previously described emulsion description, that emulsion's description will prevail. The silver halide grains used in the emulsion are usually silver bromide, silver chloride, silver iodide, silver chlorobromide, silver chloroiodide, silver iodobromide and silver chloroiodobromide. Other silver salts, for example,
Silver rhodan, silver sulfide, silver selenide, silver carbonate, silver phosphate and silver organic acid may be contained as separate grains or as a part of silver halide grains. The silver halide emulsion preferably has a distribution or a structure with respect to the halogen composition in its grain. The typical one is Japanese Examined Japanese Patent Publication 43-1
3162, JP-A-61-215540, JP-A-60-222845, JP-A-60-143331, JP-A-61-75337, etc. It is a core-shell type or double structure type particle having a composition. Further, it is not a simple double structure but a triple structure as disclosed in JP-A-60-222844, or a multilayer structure of more than that, or having different compositions on the surface of the core shell double structure particles. The silver halide can be thinly applied. In order to give a structure to the inside of the particle, not only the wrapping structure as described above but also a so-called junction structure can be formed. Examples of these are JP-A-59-133540, JP-A-58-108526, and European Patent Application No.
No. 199,290A2, JP-B-58-24772, and JP-A-59-16254. The crystal to be bonded can be generated by bonding to the edge, corner, or face of the host crystal with a composition different from that of the host crystal.
Such a junction crystal can be formed even if the host crystal has a uniform halogen composition or has a core-shell structure. In the case of a junction structure, it is naturally possible to combine silver halides with each other, but a silver salt compound not having a rock salt structure such as rhodan silver or silver carbonate may be combined with silver halide to form a junction structure. In addition, a non-silver salt compound such as lead oxide may also be used as long as a joint structure is possible. In the case of silver iodobromide grains having these structures, it is a preferred embodiment that the core portion has a higher silver iodide content than the shell portion. On the contrary, in some cases, grains having a low silver iodide content in the core portion and a high shell portion are preferable. Similarly, with respect to the grains having a junction structure, the grains having a high silver iodide content in the host crystal and having a relatively low silver iodide content in the junction crystal may be used, or vice versa. Further, the boundary portion having different halogen compositions of the particles having these structures may be a clear boundary or an unclear boundary. In addition, a positive aspect in which the composition is positively and continuously changed is also a preferred embodiment. Two
In the case of silver halide grains in which one or more silver halides exist as a mixed crystal or have a structure, it is important to control the halogen composition distribution between grains. The method of measuring the halogen composition distribution between grains is described in JP-A-60-254032. A uniform halogen distribution between grains is a desirable property. Particularly, an emulsion having a high coefficient of variation of 20% or less and high uniformity is preferable. Another preferred form is an emulsion where there is a correlation between grain size and halogen composition. For example, there is a correlation in which larger size particles have a higher iodine content, while smaller particles have a lower iodine content. Depending on the purpose, an inverse correlation or a correlation with another halogen composition can be selected. For this purpose, it is preferable to mix two or more emulsions having different compositions.

It is important to control the halogen composition near the surface of the grain. Increase the content of silver iodide near the surface,
Alternatively, increasing the silver chloride content changes the adsorbability of the dye and the developing rate, and can be selected according to the purpose.
When changing the halogen composition in the vicinity of the surface, it is possible to select either a structure that encloses the entire grain or a structure that adheres only to a part of the grain. For example, (100) plane and (111
In this case, the halogen composition is changed only on one surface of the tetrahedral grain composed of (4) planes, or the halogen composition is changed on one of the main plane and the side surface of the tabular grain.

The equivalent circle diameter of the tabular grains is preferably 0.15 to 5.0 μm. The thickness of tabular grains is 0.05 to 1.
It is preferably 0 μm. If it is less than 0.05 μm, the pressure property is deteriorated, which is not preferable. When it exceeds 1.0 μm, the merit of tabular grains cannot be fully utilized, which is not preferable.

The tabular grains preferably account for tabular grains having an aspect ratio of 3 or more in the total projected area.
It is preferably 50% or more, more preferably 80%, particularly preferably 90% or more. Further, more preferable results may be obtained by using monodisperse tabular grains. The structure and manufacturing method of the monodisperse tabular grains are described in, for example, JP-A-63-151618. Briefly describing the shape, 70% or more of the total projected area of silver halide grains has a minimum length. Occupied by a tabular silver halide having a hexagonal shape in which the ratio of the length of the side having the maximum length to the length of the side having the height is 2 or less, and having two parallel parallel surfaces as outer surfaces Furthermore, the coefficient of variation of the grain size distribution of the hexagonal silver halide tabular grains (a value obtained by dividing the variation (standard deviation) in grain size represented by the circle-converted diameter of the projected area by the average grain size) is It has a monodispersity of 20% or less. The silver halide emulsion used in the present invention is a treatment for rounding grains as disclosed in European Patent Nos. 96,727B1 and 64412B1, or West German Patent No. 2,306,447C2, JP-A-60-221320. The surface may be modified as disclosed in US Pat. A structure having a flat particle surface is generally used, but intentionally forming irregularities is sometimes preferable. A part of the crystal described in JP-A-58-106532 and JP-A-60-221320, for example, a method of forming a hole at the apex or the center of the surface, or the ruffled particles described in U.S. Pat. This is an example.

The grain size of the emulsion in the present invention is evaluated by a circle equivalent diameter of a projected area using an electron microscope, a sphere equivalent diameter of a grain volume calculated from the projected area and grain thickness, or a sphere equivalent diameter of a volume by the Coulter counter method. it can. It is to be selected from ultrafine particles having a sphere-equivalent diameter of 0.05 μm or less and coarse particles having a diameter of more than 10 μm. It is preferable to use grains of 0.1 μm or more and 3 μm or less as the photosensitive silver halide grains. A method of converting most or a very small part of the halogen composition of silver halide grains by a halogen conversion method is described in U.S. Pat.
No. 29, No. 273,430, West German Laid-Open Patent No. 3,819,241 and the like, which are effective particle forming methods. A solution of soluble halogen or silver halide grains can be added to convert it to a more sparingly soluble silver salt. It is possible to select from a method such as conversion at once, conversion by dividing into plural times, or continuous conversion. As a method of grain growth, in addition to the method of adding a soluble silver salt and a halogen salt at a constant concentration and a constant flow rate, the concentration can be changed as described in British Patent No. 1,469,480, U.S. Patent Nos. 3,650,757, and 4,242,445. A particle forming method in which the flow rate is changed or the flow rate is changed is a preferable method. By increasing the concentration or increasing the flow rate, the amount of silver halide supplied can be changed by a linear function, a quadratic function, or a more complicated function of the addition time. It is also preferable in some cases to reduce the amount of silver halide supplied, if necessary. Furthermore, when adding a plurality of soluble silver salts having different solution compositions, or when adding a plurality of soluble halogen salts having different solution compositions, an addition method in which one is increased and the other is decreased is also an effective method. Is.
A mixer for reacting a solution of a soluble silver salt and a soluble halogen salt is disclosed in U.S. Pat. Nos. 2,996,287 and 3,342,605.
