Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is suitable for producing a proof color image (color proof) from a plurality of halftone dot image information obtained by color separation and halftone image conversion in a color plate making / printing process. The present invention relates to a silver halide color photographic light-sensitive material.

[0002]

2. Description of the Related Art Conventionally, in the process of color plate making / printing, a photopolymer or a diazo compound has been used as a method for obtaining a color proof from a plurality of black and white halftone images obtained by color separation and halftone image conversion. An overlay method for forming a color image and a surprint method are known.

The overlay method is very simple and inexpensive to produce, and has the advantage that it can be used for proofreading by simply stacking four color (subtractive primary colors and black) film sheets. There is a drawback in that the overlapping produces gloss, which results in a texture different from that of the printed matter.

In the surprint method, a colored image is superposed on one support, and a method of obtaining a colored image by toner development utilizing the adhesiveness of a photopolymerizable material is disclosed in US Pat. No. 3,582,327. Nos. 3,607,264 and 3,620,726.

Further, a color proof is formed by transferring a photosensitive coloring sheet to a support, forming an image by exposure and development, laminating another coloring sheet thereon, and repeating the same process. The method of creating is 47
-27441 and JP-A-56-501217.

Further, a method is known in which a photosensitive colored sheet is used and each colored image obtained by exposing and developing the corresponding color separation film is transferred and formed on one support.
-Known as No. 97140. As the colorant of the toner and the color sheet for forming these images, the same coloring material as the printing ink can be used, and thus the color tone of the obtained color proof becomes similar to that of the printed matter.

However, these methods have the drawbacks that images must be superposed or transferred in the process of producing a color proof, which requires a long operation time and a high manufacturing cost.

As a solution to these drawbacks, a method for producing a color proof using a silver salt color photographic light-sensitive material having a white support is disclosed in JP-A-56-113139 and JP-A-5-113139.
6-104335, 62-280746, 62-280747, 62-280
No. 748, No. 62-280749, No. 62-280750, No. 62-280849, etc.

In this method, a color-separated black-and-white halftone image composed of a plurality of sheets converted from a color original into a halftone image which has been color-separated is sequentially printed on one sheet of color paper by a method such as contact printing to develop color. A color image formed by a dye formed from a coupler imagewise by color development is used as a proof image.

However, in this technique, neutral gray is reproduced from a region having a small halftone dot area (small dot) to a region having a medium halftone dot area (middle point) and a large halftone dot area (large dot). When this happens, the dot reproducibility of yellow, magenta, and cyan is slightly misaligned, the gray balance is impaired, the exposure amount varies, and the processing conditions vary, which causes variations in the neutral gray reproducibility. .

Furthermore, it is desired that the color tones of the yellow image, the magenta image, and the cyan image be approximated to the color tone of the printing ink. However, the closer the color tone is, the more the gray balance changes due to the process variation and the exposure amount variation. There is a problem that it tends to occur. Further, there is a problem that a color proof having an image having a color tone similar to that of the printing ink tends to be a color proof having no black background.

Since the absorption characteristics of the dye image obtained are very important for color reproduction, research into couplers having good absorption characteristics has recently been actively conducted.

For example, JP-A-63-123047 and JP-A-4-9051
No. 4,124,661, a pivaloylacetanilide-based yellow coupler having an alkoxy group in the anilide portion, a pivaloylacetanilide-based yellow coupler having a cycloalkyl group in the acyl portion described in JP-A-4-18042, and The asymmetric malondiamide-based yellow couplers described in Kaihei 4-174428, 4-184434, 5-11416, etc. have sharp absorption of color-forming dyes and improve color reproduction.

However, it has been found that the use of these couplers causes problems in the neutrality of dot reproduction, as described above.

2,588,982, 3,761,266, 3,761,276, 3,7
The methods described in 96,577 and British Patent 1,151,363 are known.

Although the mechanism of forming a positive image is not necessarily clear, for example, Photographic Science and Engineering (Photographic Science and Engineering)
and Engineering) Vol. 20, p. 158 (1976), it is described as follows.

Photoelectrons generated in the silver halide crystal grains by imagewise exposure are selectively trapped inside the grains to form an internal latent image. Since this internal latent image acts as an effective trap center for electrons in the conduction band, in the exposed particles, the electrons injected in the subsequent fog development process are trapped inside and assist the latent image. Become. In this case, the latent image is inside and therefore not developed by surface development. On the other hand, in particles that have not been subjected to image exposure, at least some of the injected electrons are captured on the surface of the particle and a latent image is formed there, so that the particle is developed by surface development.

The non-pre-fogged internal latent image type silver halide grains which can be used in the present invention form a latent image mainly inside the silver halide grains and have most of the photosensitive nuclei inside the grains.

A portion of the sample coated on the transparent support so as to be in the range of 1 / m ² is exposed to the light intensity scale for a predetermined time from about 0.1 second to about 1 second, and is substantially halogenated. When only the surface image of a grain not containing a silver solvent is developed using the following surface developer A at 4 ° C. for 4 minutes, another part of the same emulsion sample is similarly exposed and It is an emulsion showing a maximum density which is not larger than ⅕ of the maximum density obtained when the image is developed with the following internal developer B at 20 ° C. for 4 minutes. More preferably, the maximum density obtained with surface developer A is no greater than 1/10 of the maximum density obtained with internal developer B.

Those prepared by the method are included. For example, conversion type silver halide emulsions described in U.S. Pat.No. 2,592,250, or U.S. Pat.
Nos. 6,3,317,322 and 3,367,778, and silver halide emulsions having internally chemically sensitized silver halide grains, or U.S. Patents 3,271,157 and 3,447,927.
Emulsion having silver halide grains containing a polyvalent metal ion described in U.S. Pat. Or a silver halide emulsion comprising grains having a laminated structure described in JP-A Nos. 50-8524, 50-38525 and 53-2408, and others. Examples thereof include silver halide emulsions described in JP-A-156614 and JP-A-55-127549.

The internal latent image type silver halide grains preferably used in the present invention are silver halides having any halogen composition such as silver bromide, silver chloride, silver chlorobromide, silver chloroiodide and silver iodobromide. Any silver chloroiodobromide may be used. The grains containing silver chloride have excellent developability and are suitable for rapid processing.

The shape of the silver halide grains used in the present invention is cubic, octahedral, or a mixture of (100) and (111) faces.
It may be a tetrahedron, a shape having a (110) plane, a spherical shape, a flat shape, or the like. An average particle size of 0.05 to 3 μm can be preferably used. The grain size distribution may be a monodisperse emulsion having uniform grain size and crystal habit, or an emulsion having no uniform grain size or crystal habit, but a monodisperse silver halide emulsion having uniform grain size and crystal habit. Is preferred. In the present invention, the monodisperse silver halide emulsion means that the weight of silver halide contained within a grain size range of ± 20% centered on the average grain size r is
It means 60% or more of the total weight of silver halide grains,
It is preferably 70% or more, more preferably
80% or more. Here, the average particle diameter r is defined as the particle diameter r _i of when the product n _i × r _i ³ of the frequency n _i and r _i ³ of particles having a particle size r _i becomes maximum. (Three significant digits and the least significant digit are rounded off to the nearest four.) The grain size as used herein means the diameter of spherical silver halide grains, and the grain size of other than spherical grains. It is the diameter when the projected image is converted into a circular image of the same area. The particle size is, for example, 1 with an electron microscope.
It can be obtained by enlarging the image by 10,000 to 50,000 times and measuring the particle diameter on the print or the area at the time of projection. (It is assumed that the number of measured grains is 1000 or more indiscriminately.) A particularly preferable highly monodisperse emulsion is (grain size standard deviation / average grain size) × 100 = distribution defined by breadth (%) of distribution. Is less than 20% wide. Here, the average particle size and the particle size standard deviation are obtained from r _i defined above.

The monodisperse emulsion was prepared by adding a water-soluble silver salt solution and a water-soluble halide solution to a pAg and pH solution in a gelatin solution containing seed grains.
Under the control of the double jet method. In determining the addition rate, reference can be made to JP-A-54-48521 and JP-A-58-49938.

As a method for obtaining a more advanced monodisperse emulsion, a growth method in the presence of a tetrazaindene compound disclosed in JP-A-60-122935 can be applied.

The fog processing in the internal latent image type direct positive image formation preferably used in the present invention can be carried out by exposing the whole surface or by using a compound which generates fog nuclei, that is, a fogging agent.

The whole surface exposure is carried out by immersing the imagewise exposed light-sensitive material in a developing solution or other aqueous solution or moistening it and then uniformly exposing the whole surface. The light source used here may be any light source as long as it has light in the photosensitive wavelength region of the photographic light-sensitive material,
Further, high illuminance light such as flash light may be applied for a short time, or weak light may be applied for a long time. Further, the time of the whole surface exposure can be varied over a wide range so that the best positive image can be finally obtained depending on the photographic light-sensitive material, the development processing conditions, the kind of the light source used and the like. Further, it is most preferable that the exposure amount of the whole surface exposure gives a certain range of exposure amount in combination with the photosensitive material. Usually, when the exposure amount is excessively increased, the minimum density is increased or desensitized, and the image quality tends to be deteriorated.

Next, the fog agent preferably used in the present invention will be described.

A wide variety of compounds can be used as the fog agent used in the present invention. The fog agent only needs to be present at the time of development processing. For example, in the constituent layers other than the support of the photographic light-sensitive material (among them, In particular, it is preferably in a silver halide emulsion layer), or in a developing solution or a processing solution prior to the development processing. The amount used can be varied over a wide range depending on the purpose, and the preferable amount added is that when it is added to the silver halide emulsion layer,
1-1,500 mg, preferably 10 per mol of silver halide
~ 1,000 mg. When it is added to a processing solution such as a developing solution, the addition amount is preferably 0.01 to 5 g / liter, particularly preferably 0.05 to 1 g / liter.

(Treatment of Running Liquid) The obtained images were evaluated as follows. That is, the degree of approximation to the printing ink sample was visually evaluated in the solid image portion of the yellow image. Evaluation was carried out by three-level sensory evaluation: ◯: approximate to printing ink, Δ: somewhat approximate, and x: not approximate.

Regarding the change in the color tone of the neutral portion of the halftone image, the chart of the manuscript has Y, M and C values of 20 for each.
%, 50%, and 80%, respectively, the green light density DG and the blue light density DB of three neutral image areas having different halftone dot areas were measured and the ratio DB / DG was obtained. When the halftone dot ratio of the image in the new liquid treatment was 50%, the value of DB / DG was set as 100 and converted into a relative value for evaluation. In this way, we calculated how the neutrality changes depending on the halftone dot area ratio and processing. It is preferable that this value be close to 100.

The above results are shown in Table 1.

* Running liquid As can be seen from the results shown in Table 1, the sample of the present invention has good neutrality of the halftone dot image obtained even when the halftone dot area ratio of the original is changed, and even when the processing is changed. It turns out that it is stable. Further, it can be seen that this is further improved in the sample coated with the white pigment layer.
