[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide light-sensitive material, and in particular, it has excellent sharpness and whiteness.
The present invention relates to a silver halide color photographic light-sensitive material having rapid processing properties, and further relates to a silver halide color photographic light-sensitive material suitable for producing a color image (color proof) for proofing in a color plate making and printing process.

2. Description of the Related Art In recent years, digitization of plate making and printing processes, C
With the progress of computer-to-plate (TP), the need for DDCP (direct digital color proof) is rapidly increasing. A typical system of DDCP is laser sublimation thermal transfer, sublimation thermal transfer, ink-jet method, and a silver halide color photosensitive material containing a direct positive silver halide emulsion and a coupler is treated with an aromatic primary amine developer having a specific structure. A method of obtaining a coloring dye close to a printing color by a coupling reaction has been put to practical use. However, there is a problem in quality, price, productivity, etc. of each method, none of them satisfy all of them, and they have not yet reached widespread use. Among them, the silver proof color photographic color proof method is one of the features that a color image similar to a printing color can be obtained relatively easily and inexpensively, and that no waste material is generated. It is. On the other hand, DDCP is generally required to have the following performance. 1) Color reproducibility as close as possible to printing ink is obtained. 2) High productivity and output samples can be obtained in a short time. 3) High resolution. 4) Stable quality is always obtained. 5) Inexpensive. However, a positive type image forming method and a conventional DDCP using a silver halide color photograph processed with an aromatic primary amine developing agent having a specific structure have the following problems and have been desired to be improved. 1) The color development processing time for image formation is long. 2) The composition of the processing solution tends to fluctuate, and the stability of photographic performance is insufficient. 3) The brightness of the white background is low and the whiteness is not sufficient. 4) The sharpness of fine lines and fine characters is not sufficient. In particular, the positive type image forming method was insufficient in performance particularly in the points of 3) and 4) for the following reasons. In the positive-type image forming method, a coloring dye is formed in an unexposed portion, and a white background is formed in an exposed portion. Since the white background has a large effect on the quality if the color balance is lost or the brightness is reduced, in the positive type image forming method, excessive exposure is performed so that the stain does not occur on the white background even if the exposure amount or the processing liquid fluctuates. To form an image. However, in this method, when forming an image having a small fine line or a low halftone dot ratio on a white background, if the exposure amount is excessively applied to the periphery of the image area, the image density is reduced due to scattering of light in the photosensitive material. It has the drawback of falling down. As described above, in the positive type image forming method, both the stability of the white background and the reproducibility of the fine line are insufficient, and an improved technique has been required.

Manufactured by U.S.A.). The support generally has different stiffness values in the vertical and horizontal directions, but it is sufficient if at least one of the supports is within the above range. In the present invention, silver chloride, silver chlorobromide, silver iodobromide, silver chloroiodobromide and the like can be used as silver halide grains.
The layer contains high silver chloride grains having a silver chloride content of 95 mol% or more. It is preferable to use silver chloride, silver chlorobromide, or silver chloroiodobromide grains in which 90 mol% or more of silver halide grains are used as silver halide grains in the remaining photosensitive layers. It is preferred that the silver halide grains are high silver chloride grains having a silver chloride content of 95 mol% or more. The silver chloride content is more preferably from 95 to 99.9 mol%, even more preferably from 98 to 99.9 mol%. In particular, in the present invention, silver chlorobromide or silver chloride substantially free of silver iodide can be preferably used in order to speed up the development processing time. Here, "substantially free of silver iodide" means that the silver iodide content is 1 mol% or less, preferably 0.2 mol% or less. In the present invention, it is preferable to use a negative silver halide emulsion from the viewpoint of improving the brightness of a white background and reproducibility of fine lines. A negative-working silver halide emulsion is a type in which, when a silver halide emulsion is exposed, a latent image is formed with an increase in the exposure amount, and the dye is developed by developing with an aromatic primary amine-based developing agent. Refers to the type of emulsion to be formed.

On the other hand, in order to increase the sensitivity to high illuminance, to increase the spectral sensitization sensitivity, or to improve the aging stability of the photosensitive material, the surface of silver halide grains described in JP-A-3-84545 is used. In some cases, high silver chloride grains containing 0.01 to 3 mol% of silver iodide are preferably used. The halogen composition of the silver halide grains may be different or the same between grains, but when an emulsion having the same halogen composition is used between grains, it is easy to make the properties of each grain uniform. Regarding the distribution of the halogen composition inside the silver halide emulsion grains, the so-called uniform type grains having the same composition in any part of the silver halide grains, the core inside the silver halide grains, A particle having a so-called laminated structure having a different halogen composition from a shell (single or plural layers) surrounding the particles, or a structure having a portion having a different halogen composition in a non-layered manner inside the particle or on the particle surface (on the particle surface). In this case, particles having a structure in which portions having different compositions are bonded to edges, corners, or surfaces of the particles) can be appropriately selected and used. In order to obtain high sensitivity, it is advantageous to use one of the latter two types, rather than particles having a uniform structure, and is also preferable from the viewpoint of pressure resistance.
In the case where the silver halide grains have the above-described structure, the boundary between different portions in the halogen composition is an unclear boundary due to the formation of a mixed crystal due to a composition difference, even if the boundary is a clear boundary. Alternatively, a structure that positively has a continuous structural change may be used.

In the silver halide light-sensitive material of the present invention, the inside of silver halide grains and / or the surface of the grains are
It is preferable to use a high silver chloride emulsion having a structure having a layered or non-layered silver bromide localized phase. The halogen composition of the localized phase is preferably at least 10 mol%, more preferably more than 20 mol% in terms of silver bromide content. The content of silver bromide in the localized layer of silver bromide is determined by an X-ray diffraction method (for example, described in “Chemical Society of Japan, New Experimental Chemistry Course 6, Structural Analysis”, Maruzen) or the like. Can be analyzed. The localized phase may exist in any of the inside of the grain, the edge, the corner, and the surface of the grain, but one preferable example is a phase which is epitaxially grown at the corner of the grain. It is also effective to further increase the silver chloride content of the silver halide emulsion for the purpose of reducing the replenishment amount of the developing solution. In such a case, an emulsion of substantially pure silver chloride having a silver chloride content of 98 mol% to 100 mol% is also preferably used.

The average grain size of the silver halide grains contained in the silver halide emulsion used in the present invention (the grain size is defined by the diameter of a circle equivalent to the projected area of the grains, and the number average thereof) is 0.1. 1 μm to 2 μm is preferred. or,
The coefficient of variation of the particle size distribution (the standard deviation of the particle size distribution divided by the average particle size) is preferably 20% or less, more preferably 15% or less, and particularly preferably 10% or less. . At this time, for the purpose of obtaining a wide latitude, it is preferable to use the above monodispersed emulsion by blending it in the same layer, or to perform multi-layer coating. The shape of silver halide grains contained in the silver halide emulsion used in the present invention may be one having a regular crystal form such as cubic, tetradecahedral or octahedral, spherical or tabular.

In the color image forming method of the present invention, exposure is generally performed by scanning exposure, and the light source may be scanned or the photosensitive material may be scanned. Alternatively, both of them may be scanned. One exposure time is defined by the following equation. Exposure time = spot diameter / moving speed of light source (or moving speed of photosensitive material) Here, the spot diameter is a diameter of a spot in a direction in which a light source used for scanning exposure moves at the time of exposure (half width, unit:
μm). The moving speed of the light source is the speed at which the light source used for scanning exposure moves per unit time (unit:
μm / sec). In general, the spot diameter need not be the same as the pixel diameter, but may be larger or smaller. The number of exposures referred to in the present invention is the number of times that one point (pixel) on the photosensitive material is irradiated with light that is perceived by the same color-sensitive layer,
In the case of a plurality of irradiations, the number of exposures is 1/5 or more of the maximum exposure intensity. Therefore, 1 /
Exposure less than 5, stray light, and overlap between spots are not included in the number of times. Further, it is preferable that the number of times of giving the strength of 1/3 or more is 3 or more times.

The gradation in the present invention will be described. In the present invention, the photographic gradation of the cyan dye-forming layer, magenta dye-forming layer or yellow dye-forming layer can be measured as follows. A silver halide color photographic light-sensitive material sample is subjected to gray exposure at different exposure amounts, and color development is performed. The characteristic curve of the color-processed photosensitive material sample after processing is measured through B (peak wavelength 436 nm), G (peak wavelength 545 nm), and R (peak wavelength 645 nm) filters (half-width 30 nm) as measurement wavelengths. In each of the obtained characteristic curves, the reflection density is Dmin.
The slope of the point connecting the points +0.5 and Dmin + 1.5 is
It is defined as the photographic gradation of each dye forming layer in the present invention. Here, Dmin refers to a value including fog density. However, the evaluation of the photographic gradation is also performed under the exposure conditions and processing conditions for forming an image. One of the modes preferably used in the present invention is scanning exposure at high illuminance and for a short time. In this case, when beams are overlapped and multiple exposure is performed, the state of multiple exposure using an actual light source is used. Means the gradation. In the present invention, the gradation of the cyan dye forming layer, the magenta dye forming layer and the yellow dye forming layer is 2.3 or more, and preferably 2.5 to 5.5. In the present invention, the ratio of the yellow or cyan tone to the magenta tone is 0.7 or more and 1.10 or less.
It is preferably 5 or less, more preferably 0.8 or more and 1.2 or less, and most preferably 0.8 or more and 1.1 or less. In particular, the gradation for yellow magenta is preferably 1.0 or less. From the viewpoint of balancing the three colors of fine line bleeding, the gradation value can be reduced by setting the reflection density of the photosensitive material in an unexposed state high. That is, when the reflection density of the photosensitive material is increased, the scattering of light inside the photosensitive material is reduced, and the sharpness is improved. Therefore, even if the gradation is soft, the same sharpness is obtained. It is possible to do. For example, in a photosensitive material in which a blue photosensitive emulsion corresponds to the yellow coloring layer, the reflection density in the blue region of the unexposed photosensitive material may be increased to lower gradation and balance bleeding. it can. Further, the reflection density can be increased for the softest layer.

The following four methods can be mainly used for adjusting the gradation. 1) Control of the silver halide emulsion itself 2) Adjustment of the ratio of the silver halide emulsion to the color-forming coupler and coating amount 3) Introduction of competing compounds into the silver halide color photographic light-sensitive material 4) Control of processing solution composition Regarding the control of the silver halide emulsion itself, a desired gradation can be obtained by controlling the grain size distribution between the silver halide emulsion grains. For example, a hard gradation can be obtained by reducing the variation coefficient of the particle size distribution. In the present invention, the coefficient of variation is 0.05 or more and 0.2
0 or less, more preferably 0.06 or more and 0.1
5 or less. In the present invention, a desired gradation can be obtained by mixing two or three kinds of monodisperse emulsions having a grain size of 0.06 μm or more and a variation coefficient of 0.15 or less. It is also preferable that a complex such as rhodium, ruthenium, osmium or the like be doped into silver halide emulsion grains to obtain a high gradation of high illuminance. The preferred doping amount is from 1 × 10 ⁻¹⁰ mol to 1 × 10 ⁻⁴ mol, more preferably from 1 × 10 ⁻⁸ mol to 1 × 10 ⁻⁶ mol, per mol of silver. It is also preferable to adjust the gradation by adding an appropriate amount of a mercapto compound or a benzotriazole compound. The adjustment of the ratio of the silver halide emulsion to the color coupler and the adjustment of the coating amount will be described. When the coating amount of the silver halide emulsion and the color-forming coupler is increased, the gradation becomes hard. In order to harden the gradation without substantially increasing the maximum color density, it is preferable to increase the amount of the silver halide emulsion while keeping the amount of the coupler applied constant. The ratio of the silver halide emulsion to the coupler in the silver halide emulsion layer is preferably from 2.5 to 30 in terms of molar ratio, more preferably from 3.0 to 20 and most preferably 3.
5 or more and 15 or less. 3) The introduction of a competitor compound into a silver halide color photographic light-sensitive material will be described. By introducing a competing compound that inactivates the oxidized form of the color developing agent by reduction or nucleophilic attack into the light-sensitive material, and controlling the amount and activity thereof, the desired gradation can be controlled. As these competing compounds, the compounds described in JP-A-5-150423 and JP-A-11-65050 can be used. The competing compound is preferably added to the silver halide emulsion layer or a layer adjacent thereto, and when used in the silver halide emulsion layer, the molar ratio of the competing compound to the coupler is preferably 0.03 or more and 2.0 or less, more preferably. Is not less than 0.05 and not more than 1.0, most preferably 0.1
It is 0.7 or less. 4) The gradation can be adjusted by controlling the composition of the processing solution. For example, gradation can be controlled by adjusting the amount of color developing agent, pH, and halogen composition in the processing solution. It is also preferable to use a mercapto-based compound or a benzotriazole-based compound as a silver development-inhibiting substance, or a compound having black-and-white developability such as ascorbic acid or diethylhydroxylamine. Also,
It is also preferable to use a hydroquinone, an aminophenol or a sulfinic acid to make the contrast high.

In the present invention, the maximum color density of yellow in the yellow single color forming portion is 1.8 or less, preferably 1.7 or less and 1.3 or more. By setting the yellow density in this range, a photosensitive material suitable as a color proof for printing can be obtained. The concentration is measured using a status A B filter.

In order to incorporate the coupler of the present invention into the color light-sensitive material of the present invention, known techniques used in conventional photographic useful substances such as couplers can be applied.

Can be set. Of these, the relationship between the number of washing tanks and the amount of water in the multistage countercurrent method is described in Journal of
The Society of Motion, Picture and Television Engineers (Journalo)
f The Society of Motion P
icture and Television Engi
neers) Volume 64, p. 248-253 (1955)
May issue). Usually, the number of stages in the multistage countercurrent system is preferably 2 to 6, particularly 2 to 6.
4 is preferred.

According to the multi-stage countercurrent method, the amount of washing water can be greatly reduced, for example, 1 liter or less, preferably 0.5 liter or less per m ^{2 of the} photosensitive material, and the effect of the present invention is remarkable. As a result, there is a problem that bacteria increase due to an increase in the residence time of water in the tank, and the generated suspended matter adheres to the photosensitive material. In the processing of the color light-sensitive material of the present invention, the method of reducing calcium and magnesium described in JP-A-62-288838 can be used very effectively as a solution to such a problem. Further, isothiazolone compounds and thiabendazoles described in JP-A-57-8542,

Further, in order to prevent the growth of bacteria in the liquid and impart fungicidal properties to the processed photosensitive material, the above-mentioned various bactericides and fungicides can be used. Further, a surfactant, an optical brightener and a hardener may be added. In the processing of the light-sensitive material of the present invention, when stabilization is directly performed without going through a washing step, a method disclosed in
No. 543, No. 58-14834, No. 60-22034
All known methods described in No. 5, etc. can be used.

In addition, 1-hydroxyethylidene-1,
It is also a preferable embodiment to use a chelating agent such as 1-diphosphonic acid or ethylenediaminetetramethylenephosphonic acid, or a magnesium or bismuth compound. Also, by using a multi-stage countercurrent system as in the case of washing water, the flow of water can be greatly reduced (1 liter or less, more preferably 0.5 liter or less). The replenishment of the washing water or the stabilizing solution may be continuous or intermittent. In the latter case, it is performed according to the processing amount or at regular intervals. The pH of the washing step or the stabilizing step of the present invention is 4 to 10, preferably 5 to 8. The temperature can be variously set depending on the use and characteristics of the photosensitive material, but is generally 15 to 45 ° C, preferably 2 to 45 ° C.
0-40 ° C. The time can be set arbitrarily, but the shorter the time, the more remarkable the effect of the present invention is, and it is preferably 30 seconds to 2 minutes, more preferably 30 seconds to 1 minute 30 seconds. It is preferable that the replenishing amount is small from the viewpoints of running cost, reduction of discharge amount, handleability, and the like, and the effect of the present invention is large.

The specific amount of replenishment is 0.5 to 50 times, preferably 3 to 40 times the amount brought in from the previous bath per unit area of the photosensitive material. The liquid used in the washing and / or stabilizing step can be used in the previous step. As an example of this, the overflow of the washing water reduced by the multi-stage countercurrent method is caused to flow into a bleach-fixing bath as a preceding bath, and the bleach-fixing bath is replenished with a concentrated solution to reduce the amount of waste liquid. In the present invention, the total time of the bleach-fixing step and the washing or stabilizing step is preferably 3 minutes or less.

In the present invention, in particular, when the bleach-fixing solution contains bromide ions or iodide ions, image unevenness which occurs when the bleach-fixing solution enters the bleach-fixing solution is prevented. It is very excellent in that an image can be obtained. The preferable addition amount of bromide ion is 1 × 10 ⁻² to 2 mol per liter, and the preferable addition amount of iodide ion is 5 × 10 ^{−4 to} 5 × 10 ⁻² mol. Particularly preferred is 1/10 to 1 mole of bromide ion.
