Description

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 (hereinafter, also referred to as "light-sensitive material"), which has high sensitivity and excellent sharpness, and is wet during development processing of the light-sensitive material. The present invention relates to a silver halide color photographic light-sensitive material in which pressure fog generated in a state is improved.

[0002]

2. Description of the Related Art The technological drop of silver halide color light-sensitive materials for photography (including color negatives and color reversal light-sensitive materials; hereinafter simply referred to as color negatives) has continued to progress without delay, and conventional ultra-sensitive films have been used. The so-called ISO speed 400 class light-sensitive material has come to be used as a regular film for general users.

Many studies have been conducted to achieve high sensitivity and high image quality. For example, JP-A-58-113
No. 930, No. 58-113934, No. 59-1193.
No. 50 discloses a multi-layer color photographic light-sensitive material using a tabular silver halide emulsion having an aspect ratio of 8 or more in a high-sensitivity layer and having high sensitivity and improved graininess, sharpness and color reproducibility. Materials are disclosed. Since tabular silver halide grains have a larger surface area of grains in the same volume than cubic, octahedral or agglomerated grains, a large amount of sensitizing dye can be used and light absorption can be increased. It is advantageous to achieve high sensitivity and high image quality.

Various pressures are applied to a photographic light-sensitive material coated with a silver halide emulsion. For example, a general-purpose negative film is bent when it is rolled up in a cartridge or loaded in a camera, or is pulled to feed a frame. Further, in the developing process, for example, in an automatic developing process of transporting with a roller, pressure may be applied during transport in the developing solution or rubbing with suspended matter in the developing solution. Therefore, the pressure resistance of a photographic emulsion is a very important characteristic not only in a dry and dry state but also in a wet state.

The above-mentioned tabular silver halide emulsion is advantageous for high sensitivity, but it is also known that it has poor pressure resistance in a dry and dry state, and a method for improving it has been studied. There is. For example, JP-A-63-220238 discloses a method of introducing dislocation lines on the outer periphery of tabular grains.

It is also known that the introduction of dislocation lines into tabular grains has an influence on photographic characteristics and can achieve high sensitivity. For example, there is a description to that effect in JP-A-3-247450.

The present inventor has introduced dislocation lines on the outer circumference disclosed in JP-A-63-220238 for the purpose of achieving high sensitivity and high image quality and improving the pressure fog in a dry state. A light-sensitive material was prepared using the tabular silver halide emulsion, and various evaluations for practical use were performed. Among them, the pressure resistance in the dry state was certainly improved, but it became clear that remarkable fog was generated in the wet state corresponding to the pressure resistance in the developing solution.

However, the problem in the wet state during development processing has not been revealed so far, and improvement methods have not been studied so far, but recently, when trying to satisfy the demand for quick processing, When a photographic material is pressed or rubbed with another substance in a wet state during development processing, it may cause fogging in a scratch or abrasion state after the development processing, which is a level that is not practically acceptable. It was revealed.

As described above, the conventional technology has not been able to achieve both high sensitivity and pressure resistance in a wet state.

[0010]

It comprises a non-photosensitive layer such as an intermediate layer and a protective layer and a photosensitive layer which is a photosensitive silver halide emulsion layer. The emulsion of the present invention contains one or more tabular silver halide grains having an aspect ratio of 3 or more. Here, the tabular silver halide grains are a general term for silver halide grains having one twin plane or two or more parallel twin planes. The twin plane is defined as (1) when ions at all lattice points on both sides of the (111) plane have a mirror image relationship.
11) Surface. When viewed from above, the tabular grains have a triangular shape, a hexagonal shape, or a rounded circular shape.The triangular shape is a triangular shape, the hexagonal shape is a hexagonal shape, and the Have circular outer surfaces parallel to each other.

In the present invention, the aspect ratio of the tabular grains is a value obtained by dividing the grain diameter of each tabular grain having a grain thickness of less than 0.5 μm and a grain diameter of 0.3 μm or more (aspect ratio). ). The particle thickness can be easily measured by vapor-depositing the metal with the reference latex from the diagonal direction of the particle, measuring the shadow length on an electron micrograph, and calculating by referring to the shadow length of the latex. You can

The particle 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 the particles. The projected area of the particles can be obtained by measuring the area on an electron micrograph and correcting the photographing magnification.

The structure and manufacturing method of monodisperse tabular grains are described in, for example, JP-A No. 63-151618. Briefly describing the shape, 50% or more of the total projected area of silver halide grains is the minimum. It is occupied by a tabular silver halide having a hexagonal shape in which the ratio of the side having the maximum length to the length of the side having the length is 2 or less and having two parallel parallel surfaces as outer surfaces.

It has the following monodispersity.

US Pat. No. 4,797,354 and JP-A-2-838 describe a method for producing monodisperse hexagonal tabular grains having a high tabularization rate. Further, in European Patent No. 514,742, a polyalkylene oxide block copolymer is used and the variation coefficient of the particle size distribution is 10
% Of tabular grains are described. It is preferable to use these tabular grains in the present invention. Further, particles having a high coefficient of variation in particle thickness of 30% or less and high thickness uniformity are also preferable.

Soc. Phot. Sci. Japan, 35, 213 (1972), a direct method using a transmission electron microscope at a low temperature can be used for observation. That is, the silver halide grains taken out from the emulsion so as not to apply enough pressure to generate dislocations on the grains are placed on a mesh for observation with an electron microscope, and the sample is prepared so as to prevent damage (printout, etc.) by electron beams. Observation is performed by a transmission method in a state of cooling. In this case, the thicker the particles, the more difficult it is for the electron beam to pass therethrough. Therefore, it is possible to observe more clearly by using a high-pressure electron microscope (200 kv or more for particles having a thickness of 0.25 μm). it can. From the photographs of the particles obtained by such a method, the dislocation position of each particle when viewed from the direction perpendicular to the main plane can be determined.

The number of dislocations in the tabular grains of the present invention is 1
It is preferable that 50% (number) or more of grains containing 0 or more dislocations are present. 80% (number) or more of grains containing 10 or more dislocations are more preferable, and 20 is particularly preferable.

It can be prepared by improving the method described in 3,048, 4,439,520 and British Patent 2,112,157.

Any one of silver bromide, silver iodobromide, silver iodochlorobromide and silver chlorobromide may be used in the tabular silver halide emulsion used in the present invention. Preferred silver halide is silver iodobromide containing 30 mol% or less of silver iodide, or silver iodochlorobromide.

The silver halide emulsion of the present invention may have a double or multiple structure with respect to the halogen composition in the grains. Dislocations in the tabular grains of the present invention are introduced by providing a high iodine phase inside the grains. The high iodine phase is a silver halide solid solution containing iodine. In this case, silver iodide, silver iodobromide and silver chloroiodobromide are preferable, but silver iodide or iodobromide is preferable. Silver is preferable, and silver iodide is particularly preferable. The amount of silver halide forming the high iodine phase is 1 mol% or more and 30 mol% or less, and more preferably 3 mol% or more and 10 mol% or less, based on the silver amount of the entire grain in terms of silver amount. The phase to be grown outside the high iodine phase needs to be lower than the iodine content of the high iodine phase, and the preferable iodine content is 0 to
12 mol%, more preferably 0 to 6 mol%, most preferably 0 to 3 mol%.

The emulsion grains of the present invention have an aspect ratio of 3 or more, preferably 3 to 10 and more preferably 5 to 8. A low aspect ratio is not preferable in terms of sensitivity sharpness, and a high aspect ratio is not preferable in terms of pressure resistance.

In order to improve the sharpness, it is important to select the grain thickness in consideration of the wavelength of light incident on or exposed to the photosensitive material. 400 to 500 nm
The blue light-scattering layer or the blue-light-sensitive layer is 0.
It is preferred to arrange particles with a thickness of 08 to 0.10 μm. Next preferred is a thickness of 0.19 to 0.21 μm. 0.11 to 0.13 μm for a layer that scatters green light of 500 to 600 nm or a layer that is sensitive to green light
It is preferable to arrange particles having a thickness of. Next preferred is a thickness of 0.23 to 0.25 μm. Particles having a thickness of 0.14 to 0.17 μm are preferably arranged in a layer that scatters red light of 600 to 700 nm or a layer that is sensitive to red light. Next preferred is 0.28 to 0.3
It has a thickness of 0 μm. Particles having a thickness of 0.17 to 0.19 μm are preferably arranged in a layer that scatters infrared light or a layer that is sensitive to infrared light. When one photosensitive layer is composed of a plurality of photosensitive layers having different sensitivities, it is best to dispose grains having a preferable thickness in all layers. Next preferred is to place it in the photosensitive layer farther from the support.
It is particularly preferable to use a combination of particles having a preferable thickness in each photosensitive layer, for example, to arrange particles having a preferable thickness in both the blue light sensitive layer and the green light sensitive layer. Blue light
Any combination of green and red light sensitive layers can be selected. Reducing the thickness of the photosensitive layer for improving the sharpness is a general guideline for photosensitive material design in the art. Light-sensitive materials having a thin dry film thickness are disclosed in JP-A-61-173248 and JP-A-6-173248.
Although described and proposed in JP-A No. 2-166334, it is not preferable that the thickness of these light-sensitive materials is excessively reduced in order to improve sharpness, because pressure fog in a wet state during development processing is deteriorated. However, in the light-sensitive material of the present invention,
The total dry film thickness of the photographic constituent layers between the light-sensitive silver halide emulsion layer closest to the support and the support was measured from the light-sensitive silver halide emulsion layer closest to the support to the surface of the photographic light-sensitive material. Even if the film thickness from the photosensitive silver halide emulsion layer closest to the support, which influences the sharpness, to the surface of the light-sensitive material is reduced by making it 20% or more of the total dry film thickness, at the time of development processing. The pressure fog in the wet state did not worsen, and it became possible to make the layer thinner. This was a surprising fact that could not be expected from the above-mentioned known technology and conventional knowledge.

The preferred film thickness from the light-sensitive halide emulsion layer closest to the support of the present invention to the surface of the light-sensitive material is 10
μm to 18 μm, more preferable film thickness is 11 μm to 16 μm
m, and a more preferable film thickness is 12 μm to 14 μm.

It is well known that the film thickness of the protective layer (the layer coated on the surface side of the photosensitive layer farthest from the support) has a great influence on the sharpness of the color photographic photosensitive material.
The thickness of the protective layer is usually 2 μm to 3 μm, and sharpening is greatly improved by making it thinner than this, but the pressure fog in the wet state during development processing is greatly deteriorated, which is a practical problem. However, according to the present invention, the pressure fog in the wet state can be improved even if the thickness of the protective layer is thin, and a color photographic light-sensitive material having excellent sharpness can be obtained. The preferable thickness of the protective layer is 0.5 μm to 3 μm.
μm, and more preferably 1 μm to 2.5 μm.

The film thickness is measured by the following method. First, a commercially available contact-type film thickness meter (Anritsu Electric) was used under the condition that the temperature was controlled at 25 ° C and the relative humidity was 55% for 2 days.
Co. Ltd. K-402 BSTAND), the total film thickness of the total hydrophilic colloid layer on the side having the emulsion layer is determined by the difference in thickness before and after the coating layer on the support is removed from the sample. . The film thickness of each layer of the multilayer silver halide color light-sensitive material can be measured by enlarging and photographing the cross section using a scanning electron microscope. In the measurement of the scanning electron microscope, the sample usually has to be placed under vacuum for measurement, and it is not possible to maintain the condition of the sample that has been conditioned and dried.
There is a loss of substances with relatively low boiling points, which may result in incorrect measurement of film thickness. Therefore, sample preparation methods such as freeze-drying have been tried, but they are not sufficient. The measurement by the cross-section photography of the scanning electron microscope is used as a measuring means for calculating the thickness of each layer of the dry sample based on the value of the total film thickness by the contact type film thickness meter.

The photosensitive material of the present invention may have at least one photosensitive layer provided on a support. A typical example is a silver halide photographic light-sensitive material having at least one light-sensitive layer comprising a plurality of silver halide emulsion layers having substantially the same color sensitivity but different sensitivities on a support. It is. The photosensitive layer is a unit photosensitive layer having color sensitivity to any of blue light, green light, and red light, and in a multilayer silver halide color photographic material, the arrangement of the unit photosensitive layers is generally A red-sensitive layer, a green-sensitive layer, and a blue-sensitive layer are provided in this order from the support side. However, the order of installation may be reversed depending on the purpose, or the order of installation may be such that different photosensitive layers are sandwiched between the same color-sensitive layers. A non-light-sensitive layer may be provided between the silver halide light-sensitive layers and as the uppermost layer and the lowermost layer. These may contain a coupler, a DIR compound, a color mixing inhibitor, etc. described later. A plurality of silver halide emulsion layers constituting each unit light-sensitive layer are formed by sequentially exposing two layers, a high-speed emulsion layer and a low-speed emulsion layer, to a support as described in DE 1,121,470 or GB 923,045. It is preferable to arrange them so that the degree is low. In addition, JP-A-57-112751, 62-200350, 62-2
As described in 06541 and 62-206543, a low-sensitivity emulsion layer may be provided on the side farther from the support and a high-sensitivity emulsion layer may be provided on the side closer to the support.

Also, as described in JP-B-55-34932, the blue-sensitive layer / GH / RH / GL starts from the side farthest from the support.
/ RL can be arranged in this order. JP-A-56-2573
8, as described in JP-A-62-63936, the layers may be arranged in the order of blue-sensitive layer / GL / RL / GH / RH from the side farthest from the support. Further, as described in JP-B-49-15495, the upper layer is the silver halide emulsion layer having the highest sensitivity, the middle layer is the silver halide emulsion layer having a lower sensitivity, and the lower layer is a silver halide emulsion layer having a higher sensitivity than the middle layer. An example is an arrangement in which low silver halide emulsion layers are arranged and three layers having different sensitivities are sequentially lowered toward the support. Even when it is composed of such three layers having different sensitivities, as described in JP-A-59-202464, in the same color-sensitive layer, the medium-sensitivity emulsion layer / high-sensitivity layer is separated from the side distant from the support. You may arrange in order of a speed emulsion layer / a low speed emulsion layer. In addition, the layers may be arranged in the order of high-speed emulsion layer / low-speed emulsion layer / medium-speed emulsion layer, or low-speed emulsion layer / medium-speed emulsion layer / high-speed emulsion layer. Also, in case of 4 layers or more,
The arrangement may be changed as described above. In order to improve color reproducibility, BL, GL, described in US 4,663,271, 4,705,744, 4,707,436, JP-A-62-160448 and 63-89850, are described.
