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, and more specifically, to a silver halide color photographic light-sensitive material suitable for producing a proof color image (color proof) in a color plate making / printing process. Regarding

[0002]

BACKGROUND OF THE INVENTION Conventionally, in the process of color plate making / printing, diazo compounds and photopolymers have been used as a method for obtaining a color proof from a plurality of black and white halftone images obtained by converting color separation and halftone images. There are known an overlay method for forming a color image by a touch screen and a surprint method.

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, there is disclosed a method 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 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 by using a silver salt color photographic light-sensitive material having a white support is disclosed in JP-A-56-113139 and JP-A-56-104335. 62-280746, 62-280747, 62-
280748, 62-280749, 62-280750, 62-28084
No. 9 etc.

In this method, a color-separated black-and-white halftone image consisting of a plurality of sheets converted from color originals into color-separated halftone images is successively printed on one sheet of color paper by a method such as contact printing, and color development is performed. A color image formed by a dye formed from a coupler imagewise by color development is used as a proof image. Specifically, the yellow original document and the black original document are exposed together with blue light on the positive photosensitive material, then the magenta original document and the black original document are exposed with green light, and the cyan original document and the black original document are exposed with red light. Exposed a total of 3
After one exposure, color development processing is performed to obtain a color proof image.

The method of forming a color proof using this color photographic light-sensitive material is simple, rapid and low in cost, and as seen in Japanese Patent Laid-Open No. 2-71263, the development of a coupler coloring technology makes it much closer to printed matter. It is known to be a useful method because it is possible to obtain a finished product.

However, even if an attempt is made to obtain a color proof close to a printed matter by this method, there is a drawback that both the color image density and the black image density cannot be brought close to the printed matter. In particular, when the hue of each single color of the photographic color image is brought close to the hue of the printing ink, the tendency becomes stronger.

As means for improving this drawback, Japanese Patent Laid-Open No.
No. 122637 discloses a method in which a color image density and a black image density can be separated by newly providing a black image forming layer. However, this method also has a drawback that the number of exposures is increased and the amount of black image is increased, resulting in high cost. For this reason, it is advantageous that black is generally formed as a black ink layer by adding the density of the black image forming layer to the density of the color image.

By thus providing a new black image forming layer, it is possible to separate the color image density and the black density to reduce the color image density, and to change the hue of each single color to the hue of the printing ink. However, in general, the gradation of a color image formed by a photographic image decreases as the density decreases, and this greatly affects the gradation of dots and the quality of dots. Further, the black color formed by adding the color image density and the density of the black image forming layer is also deteriorated in the halftone dot quality, and there is a problem that the overall quality as a color proof is greatly deteriorated.

[0014]

In order to solve the above problems, the first object of the present invention is to convert a color separation and a halftone image by using a silver halide color photographic light-sensitive material (hereinafter also referred to as a color light-sensitive material). An object of the present invention is to provide a color proof having an improved degree of approximation of image quality to a printed matter when a color proof is produced from a plurality of black and white halftone image information obtained as described above. Secondly, it is to provide a color proof that has a photographic color image hue similar to that of a printed matter and is excellent in a black image. Thirdly, it is to provide a color proof that has each of the separated and developed hues similar to those of printed matter, is excellent in black images, and is excellent in halftone dot image quality.

[0015]

The object of the present invention is to provide on a support at least one yellow image-forming silver halide emulsion layer, at least one magenta image-forming silver halide emulsion layer,
And a silver halide color photographic light-sensitive material having at least one cyan image-forming silver halide emulsion layer and at least one black image-forming silver halide emulsion layer, said black image-forming silver halide Photographic processing was carried out in which the spectral sensitivity of the emulsion layer was common to the spectral sensitivity regions of the yellow image forming property, magenta image forming property and cyan image forming silver halide emulsion layer, and a color development processing step was carried out. Achieved by a silver halide color photographic light-sensitive material characterized in that each of the subsequent yellow, magenta and cyan monochromatic colors of the yellow image forming layer, magenta image forming layer and cyan image forming layer is 1.7 or more. . From the standpoint that the effects of the present invention can be more exerted, it is preferable that the monochromatic density of the color light-sensitive material is in the range of 1.5 to 1.9.

Represent The total carbon number of R ₁ , R ₂ and R ₃ is 8 or more and 22 or less. The present invention will be specifically described below.

In the present invention, the foot gradation is a characteristic curve fo
It is defined as the gradation of a photograph obtained by connecting the point intersecting with g + 0.15 and the point intersecting with D = 0.80.

The reason for defining the foot gradation in particular is that when the density of a photographic color image is lowered, a certain density range (about 1.5 to 1.
In the case of 9), the deviation of the hue from the printing ink is particularly small, and the deviation becomes large when the density is high, and the deviation is further increased when the density is low. In the halftone quality of a photographic image having continuous gradation, the gradation of the low density portion is greatly influenced, and the quality as a color proof is influenced by such a setting.

As a method for hardening the gradation at the feet, for example, in the case of a color development processing solution, the amount of the color developing agent is increased, and the amounts of hydroxylamine and sodium sulfite as preservatives are decreased, and a weak reducing agent such as xylol and sorbit is used. It can be obtained by substituting it or by increasing the amount of a penetrating agent (for example, benzyl alcohol) or by increasing the pH, temperature and time of the processing agent while adding a fog development inhibitor and a legging agent.

In the case of a light-sensitive material, a hydroquinone derivative capable of reducing an oxidized developing agent is effectively used in the light-sensitive material. Among them, the compound of the above-mentioned general formula [1] is particularly mentioned as a compound which does not adversely affect the developability, hue and the like and is effective in increasing the gradation of the undertone.

For example, an emulsion having sensitivity to any of blue light, green light, and red light as described above can be prepared, for example, by combining an emulsion having sensitivity to blue with a green-sensitizing dye and a red-sensitizing dye. .

In the emulsion layer of the light-sensitive material according to the present invention, a dye-forming coupler capable of forming a dye by a coupling reaction with an oxidant of a color developing agent can be used. The dye-forming couplers are usually selected so that a dye that absorbs the light of the light-sensitive spectrum of the emulsion layer is formed for each emulsion layer. A magenta dye forming coupler is used in the sensitive emulsion layer and a cyan dye forming coupler is used in the red sensitive emulsion layer. However, the silver halide color photographic light-sensitive material may be prepared by a method different from the above combination depending on the purpose.

It is desirable that these dye-forming couplers have a group having a carbon number of 8 or more, called a ballast group, which makes the coupler non-diffusible in the molecule. Also, these dye-forming couplers need only reduce 4 molecules of silver ion in order to form 1 molecule of dye, but they need only reduce 2 molecules of silver ion even if they are 4 equivalence. Either of two equivalence may be used. Releases a development inhibitor along with development, releases a development inhibitor at the same time as a DIR coupler that improves image sharpness and image graininess, and produces a colorless compound by coupling reaction with an oxidized product of a developing agent. DIR compounds may be used.

As is clear from the results in Table 1, the comparative sample-
In No. 1, none of them can satisfy both the color approximation and the black approximation. Comparative samples-2 and 6 have a low monochromatic density of the color image and a high black density, and are thus closer to proof printing (printing) in terms of hue, but the color image and black image co-dot quality are proofread.
