Abstract

PROBLEM TO BE SOLVED: To obtain a silver halide photosensitive material which can improve reproduction of a black printer without lowering the reproduction of white, when an image with area gradation is to be formed, by controlling the content of gelatin on the face of the photosensitive material where a silver halide emul sion is included to a specified value or smaller. SOLUTION: In the silver halide photographic material having silver halide emulsions having at least four kinds of different color sensitivities on a support body, the content of gelatin on the face where silver halide emulsions are included is controlled to 10 g/m2 or less. The different color sensitivity means to such a degree, that the image dye formed by developing a specified silver halide emulsion does not accompany formation of another image dye to be produced by developing a silver halide emulsion substantially having another color sensitivity. For example, IR-sensitive and UV-sensitive emulsions can be used as well as normally used blue-sensitive, green-sensitive and red-sensitive emulsions, and an emulsion can be selected from among the four kinds of emulsions and used.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide light-sensitive material that achieves both tightness and whiteness of an image, and more particularly to impairing the reproduction of whiteness when forming an area gradation image. The present invention relates to a silver halide light-sensitive material capable of improving the reproduction of a black plate and an image forming method using the same.

[0002]

2. Description of the Related Art Silver halide light-sensitive materials are widely used today because of their high sensitivity, excellent color reproducibility, and suitability for continuous processing. Due to these characteristics, silver halide photosensitive materials are not only used in the field of photography,
Also in the field of printing, it has been widely used in the field of so-called proofing for checking the state of finished printed matter in the middle of printing.

In the field of proofing, an image edited on a computer is output to a printing film, and after the developed film is appropriately replaced and separated and exposed, yellow, magenta and cyan images are formed. By forming an image of a printed matter on a color photographic paper, it has been performed to determine the layout of the final printed matter and the suitability of colors. In printing, black plates are used to improve color reproducibility and image tightness.However, this is not possible with proofs using ordinary color photographic paper. The reproducibility of this black plate has also been improved by combining pan-sensitive emulsions having the properties. However, in this case, since only a silver halide emulsion having photosensitivity in only three regions is used, the black plate film must be exposed by overlapping the color plate films. There is a demand for a light-sensitive material that can easily be blurred on a film existing at a position far from the photographic material and that can reproduce the image more clearly.

[0004] major drawback of the proof using a silver halide color photographic material, that there is a limit in anyway the color reproduction for use different from the printing ink dye, forming an image in a medium of high refractive index such as gelatin It has been said that in order to do so, the reproduction of white is inevitably darkened. Above all, the problem of white reproduction degrades the image description of highlights, so that there is a problem that the visual impression of the image is deteriorated.

In order to improve the tightness of the image, it is possible to achieve the object by devising so that the black plate can be reproduced independently of the three color plates. Since a silver halide emulsion is used or a material such as a coupler is frequently used, the disadvantage that whiteness is significantly deteriorated cannot be easily overcome.

Japanese Patent Application Laid-Open No. 9-160194 discloses that a silver halide light-sensitive material having four types of silver halide emulsions having different maximum spectral sensitivity wavelengths is supplied with a replenishment amount of a color developing solution of 300 ml or less per m ^{2 of the} light-sensitive material. It discloses that the dot gain of black can be approximated to that of a printed material by a color image forming method characterized by the following. However, the publication does not mention the problem of a white background, and merely discloses a light-sensitive material in which a large amount of gelatin of 11.79 g / m ² is coated on the emulsion layer side.

[0007] Japanese Patent Application Laid-Open No. Hei 7-306513 discloses that a transparent support has a lenticular surface on at least one surface thereof.
And halogenation characterized by having at least one silver halide emulsion layer or non-photosensitive hydrophilic colloid layer on the opposite side, or an oil-soluble dye and / or a colored pigment which does not substantially decolor during processing on a support. It discloses that a silver light-sensitive material can easily obtain a three-dimensional image excellent in reproducing whiteness and excellent in a three-dimensional effect even after storage of the light-sensitive material. However, the silver halide light-sensitive material disclosed in the examples of this publication is a silver halide light-sensitive material containing three kinds of silver halide emulsions, and the whiteness of the light-sensitive material by containing four kinds of silver halide emulsions is reduced. It does not mention or suggest the problem of reproduction degradation or image tightness.

The present inventors have made extensive studies on a proof system using a silver halide light-sensitive material and completed the present invention.

The above compounds are generally known, and can be easily synthesized, for example, by the method described in Harmer, "The Cyanine Soybeans and Related Compounds" (Interscience Publishers, New York, 1969). be able to.

The sensitizing dye may be added at any time from the formation of silver halide grains to the end of chemical sensitization. Further, as a method for adding these dyes, they may be dissolved in water or an organic solvent miscible with water such as methanol, ethanol, fluorinated alcohol, acetone, and dimethylformamide and added as a solution, May be added as a solution, emulsion, or suspension in a water-miscible solvent having a density of more than 1.0 g / ml.

As a method for dispersing the sensitizing dye, other than a method of mechanically pulverizing and dispersing fine particles of 1 μm or less in an aqueous system by using a high-speed stirring type disperser, see JP-A-58-105141.
As described in JP-B-60-6496, a method of mechanically pulverizing and dispersing into fine particles of 1 μm or less in an aqueous system under conditions of pH 6 to 8 and 60 to 80 ° C., and a surface tension of 38 dyne / cm described in JP-B-60-6496. A method of dispersing in the presence of a surfactant suppressed to the following, disclosed in JP-A-50-80826, is substantially free of water, is dissolved in an acid having a pKa not exceeding 5, and the solution is converted into an aqueous liquid. A method of adding and dispersing and adding this dispersion to a silver halide emulsion can be used.

Water is preferable as a dispersion medium used for dispersion, but the solubility can be adjusted by adding a small amount of an organic solvent, or the stability of the dispersion can be enhanced by adding a hydrophilic colloid such as gelatin. .

Examples of the dispersing apparatus which can be used for preparing the dispersion include a high-speed stirring type dispersing apparatus shown in FIG. 1 of JP-A-4-125563, a ball mill, a sand mill, and an ultrasonic dispersing apparatus. And the like.

In using these dispersing apparatuses, a method of performing a pre-treatment such as dry pulverization in advance and then performing a wet dispersing method as described in JP-A-4-125632 may be employed.

One form of the silver halide light-sensitive material according to the present invention is characterized in that a support comprises at least four color image forming units having different hues. The different hues mentioned here are, for example, JIS Z 8721-
Although the hue defined in 1977 may be considered, in the present invention, achromatic colors such as white, gray, and black are also expressed as having a hue for convenience, and are treated as having a hue different from other chromatic colors. That is, as a combination of colors formed by image forming units having four different hues, for example, 5Y
(Yellow), 5RP (magenta), 5BG (cyan), 5R (red), 5Y, 5RP
It may be RP, 5BG, or black. The black at this time may not be strictly black, but may be 20 or less as the metric chroma in the CIELAB color space. More preferably, it should be 10 or less.

Although the term "color image forming unit" is used, a unit necessary for forming a color image of a specific hue is collectively called a unit. For example, there are two layers containing a cyan coupler, one containing a red-sensitive silver halide emulsion and one containing a green-sensitive layer, both of which have the function of forming a cyan image. For example, these two layers are collectively referred to as a cyan image forming unit. An infrared-sensitive emulsion layer containing no coupler exists between the yellow coupler-containing layer and the magenta-containing layer (neither contains a silver halide emulsion), and is constituted so as to form a red image. If present, these three layers are red image forming units. If a magenta coupler-containing green-sensitive silver halide emulsion layer is present adjacent to the magenta coupler-containing layer, a magenta dye is formed as a function of the development of the green-sensitive silver halide emulsion, and the infrared-sensitive emulsion Since the magenta dye and the yellow dye are formed as a function of development, the magenta coupler-containing layer belongs to both the magenta image forming unit and the red image forming unit. Thus, a configuration in which a specific layer belongs to a plurality of color image forming units may be adopted.

In one embodiment of the silver halide light-sensitive material according to the present invention, the four different hues are two hues of yellow, magenta, and cyan, and one remaining hue and a hue complementary thereto. There is a feature.
This roughly categorizes the following three combinations. That is, yellow, magenta, cyan, blue yellow, magenta, cyan, green yellow, magenta, cyan, and red. A complementary color is described as a color that reproduces an achromatic color by subtractive color mixing of two colors. However, in the present invention, a slight hue shift is allowed, and a metric chroma of 20 or less in the CIELAB color space may be used. A value of 10 or less is more preferable.

One embodiment of the silver halide light-sensitive material according to the present invention includes an image forming unit having a complementary hue and a corresponding halogenated image contained in a yellow, magenta or cyan color image forming unit. At least a part of the spectral sensitivity overlaps between silver emulsions. For example, silver halide light-sensitive materials containing a red-sensitive silver halide emulsion and an infrared-sensitive emulsion in a cyan image forming unit and an infrared-sensitive silver halide emulsion in a red image-forming unit have complementary color relationships with each other. It can be seen that the spectral sensitivities of the silver halide emulsions of the color image-forming units in the area of the green light overlap. In this case, the silver halide emulsion contained in the cyan image forming unit may be a mixture of two different color-sensitive emulsions as described above, or a red-sensitive sensitizing dye and an infrared-sensitive sensitized dye. Dyes may be mixed and used.

One form of the silver halide light-sensitive material according to the present invention is characterized by containing a compound having an absorption in a visible region which is not decolored by at least one kind of processing. As the compound having absorption in the visible region which does not lose color by the treatment, a compound having an optical density after the treatment of 70% or more with respect to the optical density before the treatment is preferable.

Compounds that can be preferably used in the present invention include oil-soluble dyes. Specifically, 2
Organic dyes having a solubility in water at 0 ° C. (g / 100 g of water) of 1% or less are preferable, and typical compounds include anthraquinone compounds and azo compounds.

These oil-soluble dyes preferably have a molecular absorption coefficient at the maximum absorption wavelength at a wavelength of 400 nm or more (chloroform solution) of 5,000 or more, more preferably 20,000 or more.

As the silver halide emulsion used in the silver halide light-sensitive material according to the present invention, a surface latent image type silver halide emulsion which forms a latent image on the surface by image exposure is developed, and the emulsion is developed. A silver halide emulsion for forming an image may be used. Further, using an internal latent image type silver halide emulsion in which the surface of the grains is not previously fogged, fogging treatment (nucleation treatment) after image exposure and then surface development, or fogging treatment after image exposure. What can directly obtain a positive image by performing surface development while performing can also be used preferably. The emulsion containing the internal latent image type silver halide emulsion grains is defined as a silver halide having a photosensitive nucleus mainly inside silver halide crystal grains and forming a latent image inside the grains upon exposure. Refers to an emulsion containing grains.

One preferred form of the silver halide light-sensitive material used in the present invention is a negative silver halide emulsion. In particular, a silver halide emulsion comprising 90% by mole or more of silver chloride is preferably used. As long as it satisfies this, it may have any halogen composition such as silver chloride, silver chlorobromide, silver chloroiodobromide and silver chloroiodide.
A silver chlorobromide containing 5 mol% or more, particularly a silver halide emulsion having a portion containing silver bromide at a high concentration is preferably used, and 0.05 to 0.5 mol of silver iodide is provided near the surface. % Chloroiodide is also preferably used. In the silver halide emulsion having a portion containing silver bromide at a high concentration, the portion containing silver bromide at a high concentration may be a so-called core-shell emulsion or may be simply formed without forming a complete layer. A so-called epitaxy region in which only a region having a partially different composition may exist may be formed. It is particularly preferable that the portion where silver bromide exists at a high concentration is formed at the top of crystal grains on the surface of silver halide grains. Further, the composition may change continuously or discontinuously.

The negative working silver halide emulsion comprising preferably 90% or more of silver chloride, which is preferably used in the present invention, advantageously contains heavy metal ions. This is expected to improve so-called reciprocity failure and prevent desensitization in high-illuminance exposure and softening on the shadow side. Examples of heavy metal ions that can be used for such purposes include Group 8 to 10 metals such as iron, iridium, platinum, palladium, nickel, rhodium, osmium, ruthenium, and cobalt; and twelfth metals such as cadmium, zinc, and mercury. Group ions and ions of lead, rhenium, molybdenum, tungsten, gallium, and chromium. Among them, metal ions of iron, iridium, platinum, ruthenium, gallium and osmium are preferred. These metal ions can be added to the silver halide emulsion in the form of a salt or a complex salt. When the heavy metal ion forms a complex, examples of the ligand include cyanide ion, thiocyanate ion, cyanate ion, isothiocyanate ion, chloride ion, bromide ion, iodide ion, carbonyl, and ammonia. be able to. Among them,
Preference is given to cyanide ions, thiocyanate ions, isothiocyanate ions, chloride ions, bromide ions and the like. In order to allow the silver halide emulsion to contain heavy metal ions, the heavy metal compound may be added to any of the steps during physical ripening before formation of silver halide grains, during formation of silver halide grains, and during physical ripening after formation of silver halide grains. May be added at the location. In order to obtain a silver halide emulsion satisfying the above conditions, a heavy metal compound can be dissolved together with a halide salt and added continuously over the whole or a part of the grain forming step. Alternatively, it can be prepared by forming silver halide fine particles containing these heavy metal compounds in advance and adding them. The amount of the heavy metal ion to be added to the silver halide emulsion is preferably from 1 × 10 ⁻⁹ mol to 1 × 10 ⁻² mol, more preferably from 1 × 10 ⁻⁸ mol to 5 mol per mol of silver halide. × 10 ^-5 mol or less is preferred.

One preferred form of the silver halide emulsion used in the present invention is an internal latent image type silver halide emulsion which is not previously fogged, and the internal latent image type silver halide grains have a large photosensitive nucleus. A silver halide grain having a portion inside the grain, wherein a latent image is mainly formed inside the grain.

The effect of removing the black colloidal silver is greater than the effect of removing the yellow colloidal silver. In any case, the effect of improving the white background is obtained, and the effect of the present invention is more effectively achieved. This is a preferable embodiment of the present invention.

Example 4 Sample No. 1 of Example 1 Sample No. 104 was prepared in the same manner as in Preparation of Sample No. 104 except that the fluorescent whitening agent solid fine particles F-1 were added to the second layer at 1.40 g / m ² .

[Table 7]

Sample No. All the samples using the fluorescent whitening agent had a higher L ^* than that of Sample No. 104, and the improvement of the white background was recognized. Among them, Sample No. containing fluorescent whitening solid fine particles was used. At 401, the effect was great. On the other hand, when the oil-soluble dyes AQ-1 and AQ-2 were added to adjust the color tone of white, the effect of the fluorescent whitening agent was observed although the reduction of L ^* was inevitable. The effect of the fluorescent whitening agent is large, but the effect of increasing L ^* itself is not large. However, when an oil-soluble dye is used, the degree of correction of color is small, so that L is small. ^This is preferable because the deterioration of ^* can be kept small and the effect can be increased as a result.

Sample No. 504 and 506 do not mix silver halide emulsions having different color sensitivity, but create overlapping spectral sensitivities by using sensitizing dyes in combination. Even in such a case, the effect of the present invention can be obtained. It was found that a greater effect was obtained than mixing.
