Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a silver halide color photographic material used for producing a color proof image (color proof) by contact printing.

[Conventional technology]

In the field of printing plate making, from continuous tone images such as reversal film, color negative film, and color paper,
In the process of creating a printing plate consisting of an image consisting of halftone dots, a large amount of plate-making film is used to separate the colors,
Performs image compositing, etc. As a result, the work becomes complicated and a large number of mistakes occur, such as mistakes in characters and layout.

Furthermore, since the client (orderer) requests text changes, layout changes, color changes, etc., it is easy to forget to make corrections.In addition, it is easy to forget to make corrections.Also, it is difficult to make sure that the printed material is finished in the desired color tone and gradation. It is also necessary to check the quality of the material in advance.These are collectively called proofreading.

For this reason, in addition to trial printing called proof printing, various systems have been announced and sold for the purpose of these confirmations.

Examples include those using CRT, those using non-silver salt photosensitive materials such as 7-otopolymer and diazo, those using dry toner for image formation, and electrophotography. However, these calibration systems generally require a long time to complete the calibration of one page, have problems such as high material costs, and poor workability, so they cannot be a system that is sufficient for practical use. The current situation is that there is no such thing.

On the other hand, as another method of obtaining a proof, there is a method of printing a separation mesh original onto a color photosensitive material using color-separated light.

For example, JP-A-60-4276, JP-A-62-28074
No. 6, No. 62-280747, No. 62-280748
No. 62-280749, No. 62-280750, No. 62-280849, etc., describe a method of obtaining a calibration material on a color photosensitive material using a projection lens, and Che.

Carlson Proofmaster System
From Kreonite Inc.
There is a contact exposure method sold under the name "Proofing System".

All of these systems use positive-type or negative-type silver halide color photographic light-sensitive materials, so they can perform color proofing in a shorter time and at a lower cost than other methods, and have superior properties compared to other proofing systems. have.

In this method, color-separated black-and-white images consisting of multiple sheets of color-separated and converted black-and-white images from a color original are sequentially printed onto sheets of color paper using a method such as contact printing, and subjected to color development processing. A color image formed with dye imagewise produced from the coupler by color development is used as a proofing image.

Although the method using silver halide color photographic light-sensitive materials has the above-mentioned advantages, color proofs made from silver halide color photographic light-sensitive materials have poor surface properties due to differences in color prints and surface forming substances. There is room for improvement in the resemblance to the printed matter, and the whiteness of the white background is generally lacking, and there is also room for improvement in the adhesion and separation between the photosensitive material and the manuscript during the contact printing process. The present inventors have discovered that.

As a means for adjusting the surface roughness Ra of the image forming side of the photosensitive material of the present invention, a method of adding a matting agent to the layer on the image forming layer side of the support can be used. The layers to which the matting agent is added include a silver halide emulsion layer, a protective layer,

Another method for adjusting Ra is to set the surface roughness of the image forming layer side of the support of the photosensitive material of the present invention within the above range in the form of the photosensitive material. A method using a support such as the following can be used. In this case, the relationship between the surface roughness of the support and the surface roughness of the photosensitive material using it may be determined in advance, and a support having a surface roughness suitable for the purpose may be used.

When the image forming layer of the light-sensitive material of the present invention is an internal latent image type silver halide emulsion layer and a positive image is directly formed using this layer, the main process is to form an internal latent image type silver halide emulsion layer that has not been fogged in advance. It is common to carry out surface development of a silver photographic material after image exposure and after subjecting it to fogging treatment or while subjecting it to fogging treatment. The fogging treatment can be carried out by providing uniform exposure over the entire surface or by using a fogging agent. In this case, the entire surface uniform exposure is preferably carried out by immersing or moistening the silver halide photographic light-sensitive material in a developer or other aqueous solution, and then uniformly exposing the image-exposed internal latent image to light over the entire surface. . The light source used here may be any light within the sensitive wavelength range of the internal latent image type silver halide photographic light-sensitive material, and it is also possible to irradiate with high-intensity light such as flash light for a short time, or with a weak Light may be irradiated for a long time. The time for uniform exposure over the entire surface can be varied over a wide range depending on the internal latent image type silver halide photographic light-sensitive material, the processing conditions, and the type of light source used so as to ultimately obtain the best positive image. Further, a wide variety of compounds can be used as the above-mentioned fogging agent, and the fogging agent only needs to be present during the development process, for example, in an internal latent image type silver halide photographic material such as a silver halide emulsion layer, or Although it may be contained in a developing solution or a processing solution prior to development, it is preferably contained in an internal latent image type silver halide photographic light-sensitive material (particularly preferably in a silver halide emulsion layer). The amount used can vary widely depending on the purpose, and the preferred amount is 1 = 15 per mole of silver halide when added to a silver halide emulsion layer.

Further, examples thereof include the sale f-heterocyclic quaternary nitrogen compounds described in No. 1, and the acylhydrazinophenylthioureas described in U.S. Pat. No. 4,030,925. Further, these fogging agents can also be used in combination. For example, Research Disclosure (Research Disclosure)
RE) No. 15162 describes the use of a non-adsorption type fogging agent in combination with an adsorption type fogging agent, which can also be applied to the present invention.

When the light-sensitive material of the present invention is embodied as an internal latent image type silver halide photographic light-sensitive material, a positive image is directly formed by exposing the whole surface to light after image exposure or developing it in the presence of a fogging agent. However, any developing method may be employed as the developing method for the photosensitive material, preferably a surface developing method. This surface development processing method means processing with a developer substantially free of silver halide solvent.

In the present invention, a positive image (M image) corresponding to the original image is formed by subjecting the exposed silver halide color photographic light-sensitive material to processing using a processing solution having development processing and fixing ability. It can be made concrete.

The above-mentioned development processing includes not only color development processing but also a combination of black and white development and color development such as in reversal color processing.

Further, the processing of internal latent image type silver halide photographic light-sensitive materials includes full-surface exposure or development processing in the presence of a fogging agent, as in 8 above.

The black-and-white developer used in the development process is a so-called black-and-white first developer used in the processing of color photographic light-sensitive materials, or a black-and-white developer used in the processing of black-and-white photographic materials; It can contain a variety of well-known additives that are added to the liquid.

Typical additives include 1-phenyl-3-pyrazolidone, developing agents such as metol and hydroquinone, preservatives such as sulfites, accelerators consisting of alkalis such as sodium hydroxide, sodium carbonate, potassium carbonate, etc. Potassium bromide, 2-methylbenpanimidazole inorganic or organic inhibitors, water softeners such as polyphosphates, surface overdevelopment inhibitors consisting of trace amounts of iodides and mercapto compounds, etc. may be mentioned. can.

After color development, the silver halide photographic material of the present invention is subjected to bleaching and fixing. Bleaching treatment may be performed simultaneously with fixing treatment. Many compounds are used as bleaching agents, among them iron (III), cobalt (■), copper (I
Polyvalent metal compounds such as I), especially complex salts of these polyvalent metal cations and organic acids, such as ethylenediaminetetraacetic acid, nitrilotriacetic acid6. Aminopolycarboxylic acids such as N-hydroxyethylethylenediaminediacetic acid, metal complex salts such as malonic acid, tartaric acid, malic acid, diglycolic acid, dithioglyfuric acid, or ferricyanates, dichromates, etc. alone or in appropriate combinations. is used.

As the fixing agent, a soluble rusting agent that solubilizes silver halide as a complex salt is used. Examples of the soluble complexing agent include sodium thiosulfate, ammonium thiosulfate,
Examples include potassium thiocyanate, thiourea, and thioether.

After the fixing process, a washing process is usually performed.

Further, as an alternative to the water washing treatment, a stabilization treatment may be performed, or both may be used in combination. The stabilizing liquid used in the stabilizing treatment may contain a pH adjuster, a chelating agent, an anti-spill agent, and the like. These specific conditions are described in Japanese Unexamined Patent Publication No. 5
8-134636 etc. can be referred to.

To apply the present invention to a silver dye bleaching method, the difference in spectral absorption characteristics of the yellow dye used in the silver dye bleaching method to the printing ink is similar to the difference in the spectral absorption property of the dye generated from the yellow coupler by color development to the printing ink. Therefore, it can be easily carried out in the same manner as in the case of silver halide photographic materials using the color development method described above.
