JPS6363036A - Silver halide photographic sensitive material using reflecting support - Google Patents

Abstract

PURPOSE:To inhibit reduction in the sharpness of an image even when a reflecting support used has low transmission density, by regulating the transmission density of the reflecting support to <=0.8 and forming an antihalation layer at a position closer to the support than the position of a silver halide emulsion layer. CONSTITUTION:The transmission density of a reflecting support is regulated to <=0.8 and an antihalation layer is formed at a position closer to the support than the position of a silver halide emulsion layer. Any reflecting support having <=0.8 transmission density may be used as the reflecting support and superior water resistance is preferably provided to the surface. The antihalation layer absorbs light passed through the silver halide emulsion layer and prevents halation. Since the antihalation layer is closer to the reflecting support, light passed through the silver halide emulsion layer is reflected by the support but can not enter the emulsion layer again, so the sharpness of an image can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a silver halide photographic material, and particularly to a silver halide photographic material using a reflective support.

[Conventional technology] Thin photographic materials are desired.

That is, supports for photographic light-sensitive materials, such as reflective supports for photographs, with a thickness of about 200 to 250 μm have traditionally been used, but as has been done in recent years, it has become common to use supports for photographic materials such as conference materials, reports, etc. When the formed photosensitive material is used, the one using the above-mentioned support, which is currently in common use, is too thick and bulky when filing or storing, making it inconvenient to handle, and when it is recopied, hidden lines may appear in the copied image. There are problems such as it appearing on the screen.

For this reason, efforts are being made to make photosensitive materials thinner, but no material with satisfactory quality has yet been developed. In particular, when the support is made thinner, the transmission density decreases and the opacity decreases. As a result, the sharpness is reduced due to force halation and the like, and it is difficult to say that the image quality is sufficient for practical use.

[Purpose of the invention]

The present invention was made to solve the problem of ridges, and an object of the present invention is to suppress the deterioration of image sharpness even if the reflective support used has a small transmission Q degree. The object of the present invention is to provide a silver halide photographic light-sensitive material that can be used.

[Structure and operation of the invention]

The silver halide photographic material of the present invention has a reflective support having a transmission density of 0.8 or less, and an antihalation layer formed closer to the support than the silver halide emulsion layer. The above objective can be achieved.

According to the present invention, since the reflective support used has a transmission density of 0.8 or less, the support can be made sufficiently thin.

Furthermore, since an antihalation layer is formed, sufficient sharpness can be obtained even with such a low transmission density.

In the present invention, as a reflective support, a transmission of 4 degrees 0.8
Any reflective support can be used as long as it is as follows. For example, any material such as paper, a paper base coated with a resin or the like, synthetic paper, etc. can be used.

Although there are no particular limitations on the surface properties of the reflective support used in the present invention, it is preferable that the surface has excellent water resistance.

The water-resistant surface in this case can be formed by coating a substrate, for example a paper substrate, with a hydrophobic resin.

In an embodiment in which such a water-resistant surface is formed, even when the silver halide photographic light-sensitive material is immersed in a bath used for development processing, it is possible to prevent water from forming on the substrate.

For example, if a water-resistant surface is formed by extrusion coating a molten polyolefin onto a substrate, a polyolefin-laminated paper with excellent water resistance can be obtained.

Examples of the resin used in the hydrophobic resin coating layer coated on the surface include polyolefins such as polyethylene, polypropylene, and polybutene, olefins such as ethylene, propylene, and butene, and vinyl acetate, vinylidene chloride, and fi-hydro-maleic acid. Copolymers with monomers (e.g. ethylene-vinyl acetate copolymer, propylene-vinylidene chloride copolymer, propylene-maleic anhydride copolymer, etc.), or polystyrene, polyvinyl chloride, polyacrylate, saturated polyester, polycarbonate homopolymers or copolymers such as
Or a blend of these substances can be mentioned. The thickness of this hydrophobic resin coating layer is not particularly limited, but is generally 15
The thickness is preferably about 50 μm.

When using polyethylene resin, there is no particular restriction on its molecular weight as long as extrusion coating is possible, but polyethylene having a molecular weight in the range of 20,000 to 200,000 is usually used. In addition, the polyethylene resin used for the hydrophobic resin coating layer in this case has low density, medium density,
Any high-density polyethylene resin may be used, and these may be used alone or in combination of two or more.

In addition, a fine particle powder with higher heat resistance than the above resin, for example, a white pigment such as Ba5O, ZnO, Ti0z, etc., may be mixed with the resin (this can make the support more opaque. In this case, A thin, opaque white support with high transmission density can be obtained by mixing and extruding or stretching to form voids and whitening, or by bonding these together.

Next, the emulsion used to form the silver halide emulsion layer in the present invention will be explained.

The composition of the silver halide in the emulsion is arbitrary, and various silver halides can be used, but silver chlorobromide, silver bromoiodide, silver chloroiodide, or a mixture thereof is preferred.

The grain size of the silver halide grains in the emulsion is preferably 0.3 to 1.5 microns. There are no particular limitations on the crystal form or crystal habit of the silver halide grains used. As the crystal habit, cubic, octahedral, tetradecahedral, twinned or tabular crystal habit can be preferably used.

The emulsion may be prepared by any of the acidic method, neutral method, alkaline method, ammonia method, etc. Also forward mixing method.

Both the back mixing method and the simultaneous mixing method can be used, and p
The Ag-controlled double jet method or a layered emulsion produced by the conversion method may be used.

When implementing the photographic light-sensitive material of the present invention, a high-speed emulsion and a low-speed emulsion can be separately provided in an upper layer and a lower layer in order to control the gradation. Alternatively, they can be mixed and applied.

Next, the antihalation layer in the present invention will be described.

The antihalation layer in the present invention absorbs transmitted light transmitted through the silver halide emulsion layer to prevent halation, and the antihalation layer is formed closer to the reflective support than the silver halide emulsion layer. As a result, the light that has passed through the silver halide emulsion layer is reflected by the reflective support, and the light is prevented from entering the silver halide emulsion layer again, thereby improving the sharpness of the image.

This antihalation layer may contain any substance that absorbs transmitted light reaching this layer and prevents reflected light from entering the silver halide emulsion layer. As such a substance, for example, a substance that absorbs light in each of the blue, green, and/or red color ranges of the silver halide emulsion layer can be used. Preferably, such a substance is one that decolorizes the photosensitive material by reaction during each process of color development, bleach-fixing, and washing with water, or elutes from the photosensitive material and renders the photosensitive material colorless.

As the substance used for the antihalation layer, various organic compounds and inorganic compounds that exhibit the above-mentioned antihalation effect can be used.

Since these have good decolorizing properties, they are also effective when applied to color photographic materials.

Colloidal silver, for example gray colloidal silver, is prepared by reducing silver nitrate in gelatin by keeping it alkaline in the presence of a reducing agent such as hydroquinone, phenidone, ascorbic acid, pyrogallol, or dextrin, followed by neutralization and cooling.

It can be directly applied to positive type photosensitive materials. When applied to a color photographic light-sensitive material, it can be constructed as a light-sensitive material having, in addition to an antihalation layer, a silver halide emulsion layer containing a yellow coupler, a magenta coupler, and a cyan coupler, respectively. The purpose of increasing the sharpness of the image can be achieved even better by having the emulsion layer containing each of the above-mentioned dyes have the following layer structure. That is, a silver halide emulsion layer is formed which sequentially includes an emulsion layer containing a cyan coupler, an emulsion layer containing a magenta coupler, and an emulsion layer containing a yellow coupler from the side closest to the support. In this way, the single layer of yellow coupler was formed on the outermost surface side, rather than on the side closest to the support as in the past, because the effect of photosensitive deterioration of the yellow coupler on human vision is the least. This is because the influence on the sharpness of the image can be suppressed. On the other hand, if a layer containing cyan coupler is applied to the bottom layer, light entering from the back side of the photosensitive material layer will be absorbed by the antihalation layer, preventing deterioration of the image in the cyan coupler layer, and maintaining the sharpness of the image. can do.

Furthermore, when directly forming a positive image using the light-sensitive material of the present invention as an internal latent image type silver halide photographic light-sensitive material, the main step is to use an internal latent image type silver halide photographic light-sensitive material that has not been fogged in advance. It is common to perform surface development on a material after image exposure, 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, uniform exposure over the entire surface is achieved by immersing the image-exposed internal latent image type silver halide photographic window optical material in a developer solution or other water solution, or after soaking or soaking it in a liquid solution. Preferably, this is done by exposing to light.

The light source used here may be any light within the wavelength range to which the internal latent image type silver halide photographic window light material is sensitive; it may also be irradiated with high-intensity light such as flash light for a short period of time, or You may irradiate with weak light 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, the type of light source used, etc. so that the best positive image can be obtained in the end. Further, a wide variety of compounds can be used as the above-mentioned fogging agent, and this 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 It may be included in the developer or the processing solution prior to development, but
It is preferable to incorporate it into an internal latent image type silver halide photographic light-sensitive material (particularly preferably in a silver halide emulsion layer).

For example, Research Disclosure (Re5earc)
hDisclosure) 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.

Specific examples of useful fogging agents include hydrazine hydrochloride,
Phenylhydrazine hydrochloride, 4-methylphenylhydrazine hydrochloride, 1-formyl-2-(4-methylphenyl)hydrazine, 1-acetyl-2-phenylhydrazine, 1-acetyl-2-(4-acetamidophenyl)hydrazine, 1-methylsulfonyl-2-phenylhydrazine, 1-benzoyl-2-phenylhydrazine, 1
Hydrazine compounds such as -methylsulfonyl-2-(3-phenylsulfonamidophenyl)hydrazine, formaldehyde phenylhydrazine, and drazine can be mentioned.

When the present invention is applied to an internal latent image type silver halide photographic light-sensitive material as described above, a positive image is directly formed by exposing the entire surface 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 light-sensitive material, preferably a surface developing method. This surface development processing method means processing with a developer substantially free of silver halide solvent.

In carrying out the present invention, a positive image (visible image) corresponding to the original image can be formed by subjecting the exposed silver halide photographic material to processing using a processing solution having development and fixing ability.

I got it. The sharpness of these images was evaluated as follows.

That is, a rectangular chart of three cranes (density range D = 15) was placed closely on the obtained direct positive color photographic paper, exposed to light so that the color balance was adjusted and a gray color was obtained, and development processing was performed. In FIG. 1, reference numeral C schematically shows the original of this rectangular chart, and reference numeral CI shows a chart reproduced by exposure and development. A reproduced rectangular chart (same < Bl
) was measured using Sakura Microdensitometer PDM-5 (manufactured by Konishiroku Photo Industry Co., Ltd.),
The sharpness was compared using the density ratio of the reproduced chart C2 to the solid image, that is, D+/1.5.

The one with a larger density ratio (closer to 1 and 0) is closer to the density of the original chart, and has higher sharpness.

The density was evaluated based on the red light density of the layer closest to the support.

The development process used in this example is as follows.

The composition of the supports A-D used, and the measurement results of the density ratios of each support with and without a photographic structure provided with a first layer and a second layer, are shown in the first column. Shown in the table. The presence or absence of the first N and second layers is indicated as the presence or absence of an antihalation layer. Regarding the support, the overall thickness and the respective thicknesses of the white polyethylene layer, the middle and low layers, and the polyethylene layer on the back side were recorded, as well as the transmission density. The unit of thickness is μ (micron).

As can be seen from Table 1, if the transmission density of the support is low, the density ratio will drop significantly unless an antihalation layer is provided (Supports A and B).

The transmittance density of the support can be changed to a value close to 1.01 (see the data of C without an antihalation layer), and when an antihalation layer is provided, it is greatly improved (see the data with an antihalation layer). It can be seen that the effect of the antihalation layer is relatively small for supports whose transmission density is outside the scope of the present invention by 4 degrees, and that the present invention is effective for supports whose transmission density is 0.8 or less. (In addition, the support has a high transmission density and is thick, which goes against the basic requirement of obtaining a light-emitting material made of a thin support.)

For each sample treated as described above, sharpness was examined by density ratio in the same manner as in Example-1. The structure of the support, the presence or absence of an antihalation layer, and the development results in terms of density ratio are shown in Table 2.

The white polyethylene layer used was the same as in Example-1.

As can be seen from Table 2, when the transmittance density of the support is low, the layer change will be significantly reduced (if no antihalation layer is provided), and the layer change will be significantly reduced (see data without antihalation layer for supports A-C). ), support transmission density 1.01
In the case of (Support D), the effect of the antihalation layer is relatively small. This shows that for supports with low transmission density, providing an antihalation layer has a significant improvement effect.

When this sample was actually used for printing from a slide, the sample with the antihalation layer produced a fairly good print, but without it, the print was strong in yellow when reproduced in a small area, and the sharpness was poor. I was only able to obtain prints with poor image quality.

Example-3 The red-sensitive emulsion and green-sensitive emulsion used in Example-1 were mixed with AI, A2. To liquid A3, 2 x lO-' moles of water-soluble rhodium were added.

A sample in which emulsion layers were provided in the order of red, green, and blue light-sensitive emulsions from the support side (C, M, and Y from the bottom), and blue and green.

Samples were prepared in the order of red-sensitive emulsions (Y, M from the bottom layer).

C) was created and compared. The intermediate layer is the same as the second intermediate layer, and the sixth intermediate layer provided in Example-1. The seventh intermediate layer was removed. In this manner, the effect of a sample in which the photosensitive layer was reversed was investigated.

The results are shown in Table 3. Support B of Example 1 was used as the support, and the concentration ratio was measured for each of the three layers of blue, green, and red.

Table 3 As understood from Table 3, C, M from the lower layer.

For the Y sample, Y, M, and C samples, when no antihalation layer is provided, the concentration ratio of the bottom layer is 0.35.0.2.
7, which is quite low. Furthermore, when an antihalation layer is provided, it is considerably improved to 0.75.0.72.

However, when the lower layer was blue-sensitive N (yellow-forming layer Y), the deterioration of sharpness was not so noticeable even if the density ratio was different regardless of the presence or absence of antihalation.

On the other hand, when the lower layer was a red photosensitive layer (cyan forming layer C), the difference in antihalation was clearly visible visually, and the effect was clearly recognized.

(This is thought to occur because yellow is difficult to distinguish with the naked eye, but cyan and magenta are easy to distinguish.) As a result, the present invention can distinguish C, M, and Y from the support side. It can be seen that this method is effective for color photosensitive materials.

〔Effect of the invention〕

As mentioned above, the photographic light-sensitive material of the present invention has the effect that even if the reflective support has a low transmission 'IQ degree, deterioration in the sharpness of the resulting image can be suppressed and excellent image quality can be obtained.
