No. 201649 discloses tabular silver halide grains in which dislocation lines 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. .

[0005] 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 is used for high-sensitivity halogenation with improved graininess, gradation and fog. It has been shown that a silver emulsion is obtained.

For example, conventionally, emulsions having different grain sizes have been mixed in the same emulsion layer for the purpose of expanding the latitude and adjusting the gradation. When this is applied to tabular grains having a high aspect ratio, the stability of the coating solution is lowered, and stable production is expected to be difficult.

As described above, the conventional techniques alone have not reached a satisfactory level.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below.

In the present invention, the tabular grains having a sphere-equivalent diameter of 0.5 μm or more (referred to as A-series emulsion) are tabular silver halide grains having an aspect ratio of 6 or more. As the aspect ratio, 6 to 30 is a preferable range, and 6 to 25 is a more preferable range.

Here, the tabular grain is a general term for grains having one twin plane or two or more parallel twin planes. In this case, the twin plane refers to the (111) plane when ions at all lattice points on both sides of the (111) plane are in a mirror image relationship. The tabular grains have a triangular shape, a hexagonal shape, or a circular shape with rounded vertices when the particles are observed in a direction perpendicular to the main plane, and the triangular shape has a triangular shape or a hexagonal shape. Those having hexagonal shapes and those having circular shapes have circular outer surfaces parallel to each other.

The aspect ratio of the tabular grains in the present invention means a value obtained by dividing the equivalent circle diameter by the thickness of each tabular grain having a circle equivalent diameter of 0.1 μm or more. The thickness of the particles can be easily measured by vapor-depositing the metal from the oblique direction of the particles together with the reference latex and measuring the length of the shadow on an electron micrograph to calculate the thickness.

The equivalent circle diameter in the present invention is the diameter of a circle having an area equal to the projected area of the parallel outer surfaces of particles.

The projected area of particles is obtained by measuring the area on an electron micrograph and correcting the projection magnification.

The average aspect ratio is obtained as an arithmetic mean of the aspect ratios of at least 100 silver halide grains. It can also be determined as the ratio of the average diameter to the average thickness of the particles.

In the A series emulsion, the equivalent spherical diameter is 0.5 μm.
The tabular silver halide grains having an m or more and an aspect ratio of 6 or more are 5 times the total projected area of the silver halide grains in the A-series emulsion.
It accounts for 0% or more. Preferably 7 out of the total projected area
It is 0% or more and 100% or less.

The equivalent-sphere diameter is preferably 0.52 μm-
2.0 μm, more preferably 0.55 μm to 1.4 μm
It is.

The equivalent circle diameter is preferably 0.7 to 3.0 μm. The thickness of tabular grains is 0.05 to
It is preferably 1.0 μm. When it is less than 0.05 μm, the pressure property is deteriorated, which is not preferable. When it exceeds 1.0 μm, the advantages of tabular grains such as high sensitivity cannot be fully utilized, which is not preferable.

Further, more preferable results may be obtained by using monodisperse tabular grains. The structure and production method of monodisperse tabular grains are described in, for example, JP-A-63-151618.
According to the description of No. 1, but the shape is simply stated, 70% or more of the total projected area of the silver halide grain is the length of the side having the maximum length with respect to the length of the side having the minimum length. Is a hexagon having a ratio of 2 or less, and is occupied by tabular silver halide having two parallel outer surfaces, and the coefficient of variation of the grain size distribution of the hexagonal tabular silver halide grains is It has a monodispersity of 20% or less (the value obtained by dividing the variation (standard deviation) of the grain size represented by the circle equivalent diameter of the projected area by the average grain size).

Further, in the present invention, the tabular grains have dislocation lines. Dislocation lines of tabular grains are described, for example, in J. Am. F. Ha
Milton, Photo. Sci. Eng. , 11,5
7, (1967); Shiozawa, J .; So
c. Photo. Sci. Japan, 35, 213,
(1972) can be observed by a direct method using a transmission electron microscope at a low temperature. In other words, the silver halide grains taken out carefully so as not to apply pressure enough to generate dislocation lines from the emulsion, place them on a mesh for electron microscope observation, and to prevent damage (printout etc.) due to electron beams In the cooled state, observation is performed by the transmission method. At this time, the thicker the particles, the more difficult it is for the electron beam to pass therethrough. Therefore, it is possible to more clearly observe using a high-voltage electron microscope (200 kV or more for particles having a thickness of 0.25 μm). . From the photograph of the particles obtained by such a method, the position and the number of dislocation lines for each particle when viewed from the direction perpendicular to the main plane can be obtained.

The average number of dislocation lines is 5 or more per grain. More preferably, the average is 10 or more per particle. When dislocation lines are densely present or when dislocation lines are observed to intersect each other, the number of dislocation lines per grain may not be clearly counted. However, even in these cases, about 10
It is possible to count as many as 20 or 30.

The average number of dislocation lines per grain is calculated as the number average by counting the number of dislocation lines for 100 grains or more.

The tabular grains may have dislocation lines substantially uniformly over the entire outer circumference thereof, or may have dislocation lines at a local position on the outer circumference. That is, in the case of hexagonal tabular silver halide grains, dislocation lines may be limited only to the vicinity of six vertices, or dislocation lines may be limited to only one of the vertices. Conversely, it is also possible that the dislocation lines are limited only to the sides excluding the vicinity of the six vertices.

Introduction of dislocation lines into tabular grains can be achieved by providing a specific high silver iodide phase inside the grains.
Here, the high silver iodide phase includes a case where discontinuous high silver iodide regions are provided. Specifically, it can be obtained by preparing a base grain and then providing a high silver iodide phase and covering the outside with a layer having a lower silver iodide content than the high silver iodide phase. The silver iodide content of the base tabular grains is lower than that of the high silver iodide phase, preferably 0 to 20 mol%, more preferably 0 to 15 mol%.

The high silver iodide phase inside the grain means a silver halide solid solution containing silver iodide. The silver halide in this case is preferably silver iodide, silver iodobromide, or silver chloroiodobromide, but is preferably silver iodide or silver iodobromide (silver iodide content: 10 to 40 mol%). More preferred. In order to cause the high silver iodide phase inside the grain (hereinafter referred to as the internal high silver iodide phase) to selectively exist on any side, corner or plane of the base grain, the formation of the base grain It can be controlled by the conditions and the formation conditions of the internal high silver iodide phase and the formation conditions of the layer covering the outside thereof. As the conditions for forming the base grains, pAg (the logarithm of the reciprocal of silver ion concentration) and the presence / absence, type and amount of silver halide solvent, and temperature are important factors. By setting the pAg at the time of growing the base grain to 8.5 or less, more preferably 8 or less, the internal high silver iodide phase can be made to selectively exist in the vicinity of or on the apex of the base grain. On the other hand, the pAg during the growth of the base particles was 8.5.
As described above, more preferably 9 or more, the internal high silver iodide phase can be made to exist on the sides of the base grains. These pAg thresholds change up and down depending on the temperature and the presence / absence, type and amount of the silver halide solvent. When, for example, thiocyanate is used as the silver halide solvent, the threshold value of the pAg shifts toward a higher value. Particularly important as the pAg at the time of growth is the pAg at the end of the growth of the base grains. On the other hand, pA during growth
Even when g does not satisfy the above value, it is possible to control the selective position of the internal high silver iodide phase by adjusting the pAg to satisfy the above value after the growth of the base grains and ripening. is there. At this time, ammonia, amine compounds, thiourea derivatives, and thiocyanate salts are effective as silver halide solvents.

The so-called conversion method can be used to generate the internal high silver iodide phase. This method includes, for example, a method of adding a halogen ion having a lower solubility of a silver ion and a salt to be formed than a halogen ion forming a particle or a surface vicinity of the particle at the time of grain formation, In the present invention, it is preferable that the amount of halogen ion having a small solubility to be added to the surface area of the particle at that time is a certain value (related to halogen composition) or more. For example, it is preferable to add a KI amount in a certain range to the surface area of silver halide grains at the time of grain formation. Specifically, it is preferable to add 8.2 × 10 ⁻⁵ mol / m ² or more and 2.4 × 10 ⁻⁴ mol / m ² or less of iodide salt.

A more preferable method of forming an internal high silver iodide phase is a method of adding an aqueous silver salt solution at the same time as adding an aqueous halide salt solution containing an iodide salt.

For example, at the same time as the addition of the KI aqueous solution, AgNO
₃ Add the aqueous solution by double jet. At this time, the addition start time and the addition end time of the KI aqueous solution and the AgNO ₃ aqueous solution may be shifted before and after each other. K in KI aqueous solution
The addition molar ratio of Ag in the AgNO ₃ aqueous solution to I is preferably 0.1 or more, more preferably 0.5 or more. More preferably, it is 1 or more. The total added molar amount of the AgNO ₃ aqueous solution may be in the silver excess region with respect to the halogen ions and the added iodine ions in the system. It is preferable that pAg at the time of the double jet addition of the halide aqueous solution containing these iodine ions and the silver salt aqueous solution be decreased with the addition time of the double jet. The pAg before the start of addition is preferably 6.5 or more and 13 or less. More preferably, it is 7.0 or more and 11 or less. PA at the end of addition
Most preferably, g is 6.5 or more and 10.0 or less.

When carrying out the above method, it is preferable that the solubility of the silver halide in the mixed system is as low as possible. Therefore, the temperature of the mixed system for forming the high silver iodide phase is preferably 30 ° C. or higher and 80 ° C. or lower, more preferably 30 ° C. or higher and 7 ° C. or higher.
0 ° C. or less.

Most preferably, the formation of the internal high silver iodide phase is fine grain silver iodide (fine silver iodide, hereinafter the same).
Alternatively, fine grain silver iodobromide, fine grain silver chloroiodide, or fine grain silver chloroiodobromide can be added. In particular, it is preferable to add fine grain silver iodide. These fine particles usually have a particle size having a sphere-equivalent diameter of 0.01 μm or more and 0.1 μm or less, but 0.01 μm or less or 0.1 μm or less.
Fine particles having a particle size having a sphere-equivalent diameter of not less than μm can also be used. Regarding the preparation method of these fine grain silver halide grains, JP-A-1-183417 and 2-0.
No. 44335, No. 1-183644, No. 1-1836
No. 45, No. 2-043534 and No. 2-04353.
The description regarding No. 5 can be referred to. An internal high silver iodide phase can be provided by adding and ripening these fine grain silver halides. When the fine particles are dissolved by ripening, the above-mentioned silver halide solvent can be used. It is not necessary that all of the added fine particles dissolve and disappear immediately, and it is sufficient that the fine particles dissolve and disappear when the final particles are completed.

The amount of silver halide forming the internal high silver iodide phase is 30 mol% or less, more preferably 20 mol% or less, based on the total amount of silver in terms of silver amount.

These high silver iodide phases can be observed and learned from Journal of Imaging Science and Technology, Vol. 38, page 10 (1994).

The silver iodide content of the outer layer covering the internal high silver iodide phase is lower than the silver iodide content of the high silver iodide phase, preferably the silver iodide content is 0 to 30 mol%. , More preferably 0 to 20 mol%, most preferably 0 to 10 mol%.

The temperature at the time of forming the outer layer covering the internal high silver iodide phase, pAg, is arbitrary, but the preferred temperature is 3.
0 ° C. or higher and 80 ° C. or lower. Most preferably, it is 35 ° C or more and 70 ° C or less. Preferred pAg is 6.5 or more and 1
1.5 or less. In some cases, it is preferable to use the above-mentioned silver halide solvent, and the most preferable silver halide solvent is a thiocyanate salt.

Another method of introducing dislocation lines into tabular grains is to prepare base grains, deposit halosilver chloride, and convert the halosilver chloride to form a high silver bromide or high silver iodide layer. , There is a method of further providing a shell on the outside. Examples of the silver halochloride include silver chloride or silver chlorobromide or silver chloroiodobromide having a silver chloride content of 10 mol% or more, preferably 60 mol% or more. Deposition of these halosilver chlorides on the base grains can be carried out by adding an aqueous solution of silver nitrate and an appropriate aqueous solution of an alkali metal salt (for example, potassium chloride) separately or simultaneously, or by adding an emulsion comprising these silver salts. It can also be deposited by aging. Deposition of these silver halochlorides is possible in all pAg regions, but most preferably 5.
It is 0 or more and 9.5 or less. The amount of the silver halochloride layer is 1 mol% or more and 80 mol% or less in terms of silver mol% based on the base grains. More preferably, it is 2 mol% or more and 60 mol% or less. It is possible to introduce dislocation lines into tabular grains by converting this halosilver chloride layer with an aqueous solution of a halide capable of forming a silver salt having a solubility lower than that of silver halochloride. After converting the silver halochloride layer with, for example, an aqueous KI solution, the shell can be grown to obtain the final grains. The halogen conversion of these halosilver chloride layers does not mean that all of them are replaced with silver salts having lower solubility than halosilver chloride, and preferably 5% or more, more preferably 10% or more, most preferably 20% or more. Replaces the less soluble silver salt.

By controlling the halogen structure of the base grain on which the halosilver chloride layer is provided, it is possible to introduce dislocation lines at local sites on the principal plane. For example, when a base grain having an internal silver iodide-rich structure displaced in the lateral direction of the base tabular grain is used, dislocation lines can be introduced only into the main plane of the peripheral part excluding the center part of the main plane. When the base grains having an outer silver iodide-rich structure are displaced in the lateral direction of the base tabular grains, dislocation lines can be introduced only into the central portion excluding the peripheral portion of the main plane. Further, it is possible to deposit a halosilver chloride only on a site limited in area by using a locally dominant substance for epitaxial growth of halosilver chloride, for example, iodide, and introduce a dislocation line only to the site. The temperature during the deposition of silver halochloride is preferably 30 ° C or higher and 70 ° C or lower, more preferably 30 ° C or higher and 50 ° C or lower. It is possible to perform conversion after the deposition of the silver halochloride and then grow the shell, but it is also possible to perform the halogen conversion while growing the shell after the deposition of the silver halochloride.

The silver iodide content of the shell is preferably 0-3.
0 mol%, more preferably 0 to 20 mol%. The temperature at the time of shell formation and pAg are arbitrary, but the preferred temperature is 30 ° C. or higher and 80 ° C. or lower. Most preferably 35
It is above 70 ° C. A preferable pAg is 6.5 or more and 11.5 or less. In some cases, it is preferable to use the above-mentioned silver halide solvent, and the most preferable silver halide solvent is a thiocyanate salt. In the final grain, the internal halosilver chloride layer that has undergone halogen conversion will be affected by the conditions such as the degree of halogen conversion, and the above-mentioned Journal of Imaging Science and Technology 3
It may not be confirmed by the halogen composition analysis method described in Volume 8. However, dislocation lines are clearly observable.

Further, in the present invention, JP-A-6-25874 is used.
The dislocation introduction method using an iodide ion-releasing agent described in No. 5 can also be preferably used.

It is also possible to introduce the dislocation lines by appropriately combining the method of introducing the dislocation lines and the method of introducing the dislocation lines described above.

It is preferably 0.55 μm. The thickness of the tabular grains is preferably 0.05 to 0.3 μm.

The position of the internal high silver iodide phase provided for introducing the dislocation line is not particularly limited, but is preferably within the range of the following formula (1).

Formula (1) D = (1.4S ^1.5 ) × 100 ± 15 Here, D is the amount (%) of silver consumed until the dislocation line is introduced with respect to the total amount of silver consumed (that is, dislocation introduction). (Position or dislocation start position), S represents the equivalent spherical diameter of the final particle in μm. However, when D is less than 5, D is set to 5.

The range of ± 15 is preferably ± 10, more preferably ± 5.

The silver halide grains used in the B series emulsion are
Silver iodobromide and silver bromide are preferred, silver iodobromide having a silver iodide content of 0.1 to 8 mol%, and most preferably 1 to 5 mol. % Silver iodobromide.

In the present invention, the A-series emulsion and the B-series emulsion may coexist in the light-sensitive material, and they may be contained in different layers in the same light-sensitive material separately or in the same light-sensitive material. It can be contained in one layer. However, it is preferable to include both emulsions in the same layer.
When the A-series emulsion and the B-series emulsion are contained in the same layer, the mixing ratio thereof can be freely set according to the desired sensitivity and gradation. When the light-sensitive material has a plurality of silver halide emulsion layers, the A-series emulsion and the B-series emulsion may be contained in at least one emulsion layer, and may be contained in all layers. .

The emulsions used are A series emulsion and B emulsion.
It may be a mixed emulsion consisting of one type of each series emulsion,
One or both of them may be a mixed emulsion composed of two or more kinds of emulsions.

The following is a description of the emulsions utilized in the present invention (ie, emulsions defined in the present invention as meeting certain requirements, and emulsions otherwise available). 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 structure with respect to the halogen composition in its grains. A typical example thereof is, for example, Japanese Patent Publication No.
No. 62, JP-A-61-215540 and JP-A-60-2
No. 22845, JP-A-60-143331, JP-A-6-143331
It is a core-shell type or double structure type grain having a halogen composition in which the inside and the surface layer of the grain are different as disclosed in 1-75337. In addition to a simple structure, a triple structure as disclosed in Japanese Patent Application Laid-Open No. 60-222844, or a multilayer structure of more than that, or a different composition on the surface of a core-shell double structure particle Or a thin silver halide having the following formula:

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 bonded structure can be prepared. These include, for example, JP-A-59-133540 and JP-A-58-108526.
No., European Patent Application No. 199,290A2, JP-B-58
No. 24,772 and JP-A No. 59-16254.

The crystal to be bonded can be formed 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 type structure. In the case of the junction structure, it is naturally possible to combine the silver halides, but for example, a silver salt compound not having a rock salt structure such as silver rhodan and silver carbonate may be combined with the silver halide to form the 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 grains such as silver iodobromide 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, grains having a junction structure may be grains having a high silver iodide content in the host crystal and relatively low silver iodide content in the junction crystal, or vice versa. Further, the boundary portions having different halogen compositions of the grains having these structures may be clear boundaries or unclear boundaries. In addition, a configuration in which the composition is positively and continuously changed is also a preferable embodiment.

In the case of silver halide grains in which two 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 for measuring the halogen composition distribution between grains is described in JP-A-60-254032. Uniform halogen distribution between grains is a desirable property. In particular, a highly uniform emulsion having a coefficient of variation of 20% or less is preferable.
Another preferred form is an emulsion where there is a correlation between grain size and halogen composition. As an example, there is a correlation such that the iodine content is higher for larger size particles, while the iodine content is lower for smaller size particles. 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 silver iodide content near the surface,
Alternatively, increasing the silver chloride content can be selected according to the purpose because the adsorption property of the dye and the developing speed are changed.
When changing the halogen composition in the vicinity of the surface, either a structure that wraps the entire grain or a structure that adheres only to a part of the grain can be selected. For example, (100) plane and (1
11) The case where the halogen composition is changed only on one side of a tetrahedral grain composed of planes, or the halogen composition on one of the main plane and the side face of the tabular grain is changed.

The equivalent circle diameter of the tabular grains is 0.15 to 3.0.
μm is preferred.

The thickness of tabular grains is 0.05 to 1.0.
μm is preferred.

If it is less than 0.05 μm, the pressure property is deteriorated, which is not preferable. If it exceeds 1.0 μm, the advantages of tabular grains cannot be fully utilized, which is not preferable.

The tabular grains preferably account for 50% or more, more preferably 80%, and particularly preferably 90% of the total projected area of tabular grains having an aspect ratio of 3 or more.
% Or more.

Further, when monodisperse tabular grains are used, more preferable results may be obtained. 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 having a ratio of the length of the side having the maximum length to the length of the side having the height of 2 or less and having two parallel parallel outer surfaces. Furthermore, the coefficient of variation of the grain size distribution of the hexagonal silver halide tabular grains (the value obtained by dividing the variation (standard deviation) in grain size represented by the circle equivalent diameter of the projected area by the average grain size) is 20. It has a monodispersity of not more than%.

The silver halide emulsion used in the present invention is, for example, EP 96,727 B1 or EP 64,412.
The particles may be rounded as disclosed in B1 or the surface may be modified as disclosed in West German Patent No. 2,306,447C2 and JP-A-60-221320. .

A structure having a flat particle surface is generally used.
It is preferable in some cases to form irregularities intentionally.

The above results are shown in Tables 2 and 3.

[Table 3]

Table 2 shows that the introduction of dislocation lines can increase the sensitivity (for example, emulsions A-1 to A-
2 to Emulsions A-3 to A-5, Emulsions B-1 to B-3 to Emulsions B-4 to B-9).

It is also understood that the sensitivity increases as the aspect ratio increases (for example, emulsions A-3 to A-5).
In the emulsions B-4 to B-9).

From Table 3, the performance of the mixed emulsions is compared.
The sensitivity of any of the mixed emulsion systems is close to that of the large size emulsion (A series emulsion).

When the A-series emulsion has no dislocation lines, it can be seen that the sensitivity decreases remarkably with the passage of time of the coating solution, regardless of the mixing with any small size emulsion (B-series emulsion). 101-108).

When the A-series emulsion has a dislocation line, the sensitivity of the coating solution due to mixing with a B-series emulsion having no dislocation line is greatly lowered with time (for example, Sample 10
9, 111, 119). On the other hand, when mixed with a B-series emulsion having a dislocation line, it can be seen that the sensitivity decrease with time of the coating solution is small specifically in the aspect ratio of the B-series emulsion in the range of 2 to 5 (for example, Samples 112 and 117). To Samples 113-116 and Samples 121 and 125 to Sample 1
22-124).

It can be seen that the effect is more remarkable when the dislocation line of the B-series emulsion is in the preferable range described in the specification (the dislocation line introduction position of sample 115 is 55% <up to the dislocation line introduction position). This means that the silver nitrate is 55% with respect to the silver nitrate used for forming all grains> with respect to the dislocation line introduction position of the sample 114 (45%).

It was made. The obtained sample was evaluated in exactly the same manner as in Example 1. The results are summarized in Table 4.
