Abstract

PURPOSE:To reduce noises in a picture image such as halation by preventing substantially transmission of visible light through a base and/or a nonsensitive layer provided nearer the base side than a silver halide emulsion-contg. photosensitive layer which is nearest the base at one or both sides of the base. CONSTITUTION:In a reflection type photosensitive material having each at least one layer of silver halide emulsion on both sides of a base, the base and/or a nonphotosensitive layer arranged nearer the base side than a silver halide emulsion-contg. photosensitive layer which is nearest the base at one or both sides of the base, is prevented substantially from transmission of visible light. In this case, the expression 'substantially nontransmittable for visible light' means that the transmittance for light from a base side layer nearer the photosensitive layer which is nearest the base at one surface of the base to the base side layer nearer the base which is nearest the base at another side of the base is >=2% basing on the whole visible light. It is more preferred to be <=1%. By this constitution, the dispersion in the printing work for reducing picture image noise is lessened.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a silver halide photosensitive material, and particularly to a novel silver halide photosensitive material that provides double-sided images with little noise.

(Prior Art) Conventional reflective silver halide photographic materials are made by dispersing photosensitive silver halide particles such as silver bromide or silver chloride in a water-soluble binder and depositing them on one side of a paper or opaque plastic support. It is constructed by coating. In black and white photosensitive materials,
In the normal development process, hydroquinone, phenidone,
A developing agent such as metol reduces the exposed silver halide grains to form a silver image, thereby obtaining an image. On the other hand, in the case of color photographic materials, there are generally three colors: blue, green, and red.
The silver halide emulsion layers are sensitive to each primary color, and each develops yellow, magenta, and cyan.
Reproduces color images based on the so-called subtractive color method. This coloring is usually caused by the aromatic primary amine color developing agent itself being oxidized when reducing the exposed silver halide grains.
This is done by reacting this oxidant with a coupler to form a dye.

(Problems to be Solved by the Invention) However, conventional photosensitive materials have the disadvantage that they are bulky for storage because only one side of the support is used to form a photographic image. In order to solve this problem, it may be possible to coat both sides of the support with photographic photosensitive layers, and examples of photosensitive materials that utilize both sides of the support include those that use a transparent support such as X-ray film. There is. However, in the case of a normal reflective support, there is a problem in that part of the photosensitive layer on the back side reacts even when the front side is exposed, resulting in double images and image noise. was.

The present invention was made in view of these problems, and an object of the present invention is to provide a new reflective silver halide photosensitive material that can form double-sided images of excellent image quality. do.

That is, a first object of the present invention is to provide a reflective double-sided photosensitive material with less image noise such as reflection. Second
The purpose of this invention is to provide a silver halide photosensitive material that is not bulky during storage.

(Means for solving the problem) This purpose is to provide at least one layer on each side of the support.
In a reflective light-sensitive material having a silver halide emulsion layer, the non-light-sensitive layer and/or support located on the support side of the silver halide emulsion-containing light-sensitive layer closest to the support on one or both sides of the support is substantially It has been discovered that this can be achieved by using a reflective silver halide photographic material that is characterized by not transmitting visible light.

In the present invention, "substantially not transmitting visible light" means
The light transmittance from the layer closest to the support than the photosensitive layer on one side of the support to the layer closest to the support than the photosensitive layer closest to the support on the other side of the support is the total visible light 2% or less compared to To obtain a more favorable reduced image noise, the light transmittance is 1%.
It is preferable that it is below.

This light transmittance can be measured from behind by placing the sample in front of the integrating sphere. That is, it is defined as including not only the straight component of the transmitted light but also the scattered transmitted light.

By setting the light transmittance to 2% or less, a reflective double-sided photosensitive material with low image noise and little variation in printing operations, that is, a high safety factor, can be obtained.

Some of the methods for making the visible light substantially invisible are shown below, but the present invention is not limited thereto.

The first method is to provide a layer containing a dye that can be decolorized during development processing closer to the support than the photosensitive layer containing the silver halide emulsion closest to the support.

The dye is preferably one that absorbs visible light and is further washed away into the processing solution or washing water during the development process, or one that is bleached by components in the processing solution, such as sodium sulfite. Furthermore, it is desirable to use two or more kinds of dyes in combination in order to absorb light in the necessary range of visible light. Further, in order to prevent the dye from oozing out from the additive layer, it is desirable to use a mordant (for example, a cationic polymer) in combination. The layer containing this dye may be provided only on one side of the support, but
It is desirable to provide it on both sides. As such a dye,
Particularly preferred are oxanol dyes, hemioxonol dyes, styryl dyes, merocyanine dyes, anthraquinone dyes, azo dyes, cyanine dyes, azomethine dyes, triarylmethane dyes, phthalocyanine dyes, and the like.

The second method is to provide a layer of black colloidal silver that is desilvered during development and vines on the support side of the silver halide emulsion-containing photosensitive layer closest to the support. This method is especially
It is useful in silver halide color photographic materials that have a bleach bath or bleach-fix bath during the development process. The layer containing black colloidal silver may be provided only on one side of the support, but it is more desirable to provide it on both sides.

The third method is to provide a light-impermeable layer in the support, and methods for providing the light-impermeable layer include the following methods.

For example, a black pigment such as carbon black, black colloidal silver, or a dye such as black ink is used. In the method of incorporating black pigments and dyes into the support, the material of the support is polyethylene.

In the case of laminated paper, it is possible to use methods such as mixing it with pulp (or dyeing it) or dispersing it in polyethylene and laminating it. In the case of synthetic paper (plastic film, etc.), pigments (dyes) are dispersed in polymers. or by including such a layer in a plastic film. In the case of baryta paper, a black layer is provided within the paper or below the baryta layer.

Alternatively, a thin metal film of aluminum, zinc, copper, lead, etc. is used as the light-opaque layer. The metal layer is, for example, disclosed in Japanese Patent Publication No. 59-
It can be provided on a support by the method described in Japanese Patent Publication No. 41573 and Japanese Patent Publication No. 57-10420.

In the third method of providing a light-opaque layer in the support, it is desirable to further provide a layer containing a white pigment (a plastic layer, a gelatin dispersion layer, etc.) on both sides of the light-opaque layer. As the white pigment, titanium oxide (anatase type, rutile type), barium sulfate, zinc oxide, etc. are preferably used. Further, it is sufficient that the light-opaque layer is located at any one location in the support, but it may be located on both sides of the support material (paper, etc.).

In any of the methods 1.2 and 3 above, the light opacity of the present invention can be adjusted arbitrarily by appropriately selecting the amount of the substance used (dye, pigment, etc.), layer thickness, etc. Can be done. Furthermore, the amount to be used, layer thickness, etc. are not particularly limited, as they depend on the transmittance of the support itself and other factors.

The uppermost layer (protective layer) of the photosensitive material according to the present invention has an average particle size of 0. It is desirable to use a matting agent with a diameter of 2 μm or more and 4 μm or less because failures such as adhesion are less likely to occur even when photosensitive materials and prints are stacked. The desirable usage amount is 1mg or more per 1m' of photosensitive material 1000m
g or less, more preferably 10 mg or more and 300 mg
It is as follows. As matting agents that remain after development, polymer particles such as polymethyl methacrylate and inorganic compound particles such as silica are used. Furthermore, particles of inorganic compounds such as silver halide and polymer particles are used as particles that dissolve during the development process.

In a preferred embodiment of the light-sensitive material of the present invention, the support has at least one each of a red-sensitive emulsion layer, a green-sensitive emulsion layer, and a blue-sensitive emulsion layer. The order of these layers can be arbitrarily selected as necessary. The preferred order of layer arrangement is red sensitivity, green sensitivity, and blue sensitivity from the support side, or green sensitivity, red sensitivity, and blue sensitivity from the support side. Further, each of the above emulsion layers may be made up of two or more emulsion layers having different sensitivities, or a non-light-sensitive layer may exist between two or more emulsion layers having the same sensitivity. . To form a color image, the red-sensitive emulsion layer contains a non-diffusible cyan-forming coupler, the green-sensitive emulsion layer contains a non-diffusible magenta-forming coupler, and the blue-sensitive emulsion layer contains a non-diffusible yellow-forming coupler. However, different combinations may be used depending on the case, and other dye image-forming compounds may also be used. As for the non-diffusible cyan, magenta and yellow couplers, those described, for example, in Japanese Patent Application No. 61-286367, page 48, line 14 to page 57, can be used.

Further, one yellow filter layer is usually provided at least one of the blue-sensitive layer, the green-sensitive layer, and the red-sensitive layer.

The silver halide used in the present invention may be any of silver chloride, silver bromide, silver chlorobromide, silver iodobromide, and silver chloroiodobromide, but silver chlorobromide, which does not substantially contain silver iodide, may be used. Particularly preferred. "Substantially free of silver iodide" means that the amount of silver gold ash is 0 to 1 mol%,
Preferably it is 0 to 0.5 mol%. More preferred is silver chlorobromide containing no silver iodide.

The internal latent image type emulsion may be a conversion type emulsion or a core/shell type emulsion, but a core/shell type emulsion is preferred. When using a core/shell type emulsion, the silver chloride content in the silver chlorobromide grains may be higher in the core or higher in the shell, but the silver chloride content may be higher in the shell or the halogen composition of the core and shell may be the same. It is preferable that

When using the internal latent image type photosensitive material of the present invention, after imagewise exposure, after or during fogging treatment with light or a nucleating agent, surface development containing an aromatic primary amine color developer is performed.

In order to form a color image by a color diffusion transfer method using the photosensitive material of the present invention, a black and white developer such as a phenidone derivative may be used instead of the above-mentioned color developer.

After color development, the photographic emulsion layer is usually bleached.

The bleaching process may be carried out simultaneously with the fixing process in a single bath bleach-fixing process, or may be carried out separately. Furthermore, in order to speed up the processing, a method may be employed in which bleaching is followed by bleach-fixing, or a method in which fixing is followed by bleach-fixing. Aminopolycarboxylic acid iron complex salts are usually used as bleaching agents in bleaching solutions or bleach-fixing solutions. As additives used in bleaching solutions or bleach-fixing solutions,

Water was passed through a mixed bed column packed with a strongly acidic cation exchange resin (Amberlite IR-120B manufactured by Rohm and Haas) and an ○H type anion exchange resin (Amberlite IR-400) to remove calcium and magnetism. The sodium ion concentration was reduced to below 3 mg/l, followed by treatment with sodium dichloride and anurate at 20 mg/i! and sodium sulfate 1.5 g/R were added. The pH of this solution is 6.5~
It is in the range of 7°5.

The results are shown in Table 3.

Table 3 *L) The value of the reflection on the back side is determined by the degree to which the light from the white part of the Macbeth checker printed on one side (the front side) leaks through the support and exposes the back side, and the Dmax value. Expressed as a value of decline.

The photosensitive material of the present invention is very preferable because it has little transfer to the back side.

(Effects of the Invention) According to the present invention, a reflective double-sided silver halide photosensitive material which is not bulky during storage and has less image noise such as blurring can be obtained.

Claims (1)

[Claims] In a light-sensitive material having at least one silver halide emulsion layer on each side of the support, a non-light-sensitive layer on one or both sides of the support is located closer to the support than the silver halide emulsion-containing light-sensitive layer closest to the support; A reflective silver halide photographic material characterized in that/or the support substantially does not transmit visible light.
