Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a silver halide color light-sensitive material for stereoscopic photography that has excellent stereoscopic effect and color reproducibility, and also relates to a silver halide color light-sensitive material for stereoscopic photography, which is suitable for producing images for obtaining stereoscopic color photographic prints or slides. Regarding the formation method.

(Prior art) At present, attempts are being made to create images that can be viewed stereoscopically in some movies and televisions, but with the recent spread of silver halide photosensitive materials, it is possible to view stereoscopic images using silver halide photosensitive materials. There is a request to obtain an image.

For information on how to create stereoscopic images, see Euclid (
Since Euclid) pointed out that the sense of perspective is created by the parallax between the two eyes, various efforts have been made.
For example, it is described in the Photographic Technology Handbook, Chapter 20 (pages 863-881) (Corona Publishing, published in 1987).

One photographic method that allows for easy stereoscopic viewing is a method in which at least two photographs taken with at least two different parallaxes are viewed simultaneously with both eyes.

For details, see how to view two photos stereoscopically as one photo by viewing them with the left eye and right eye respectively (two-lens piyua ichikankan method).
and information from at least two original photographs taken by incorporating a lenticule into a photographic optical system or at least two photographic optical systems is compressed and printed on a silver halide photosensitive material having a lenticular sheet. How to view stereoscopically as a single photograph (

(Problems to be Solved by the Present Invention) However, the stereoscopic images obtained by the method described in the above technology lack so-called stereoscopic effect and powerful feeling, and are not fully satisfactory images.

Furthermore, conventionally, in order to take stereoscopic photographs, it was necessary to use a so-called special stereo camera, which was expensive.

Moreover, even though such a special stereo camera was used, the color images obtained had poor color reproducibility and sharpness, and were not attractive as stereoscopic photographs.

In particular, with the recent improvements in the performance of silver halide photosensitive materials, there is a growing desire to easily obtain high-quality, excellent images with better three-dimensionality that can be obtained with ordinary silver halide photosensitive materials. Demand is high.

Accordingly, a first object of the present invention is to provide a silver halide color light-sensitive material for stereoscopic photography which can improve the stereoscopic effect of the above-mentioned stereoscopic photography and has high image quality, and an image forming method for stereoscopic color photography. It is in.

An object of the present invention is to provide an image forming method for stereoscopic color photography.

A third object of the present invention is to provide a silver halide color photographic material and a method for forming a three-dimensional color photographic image, which can quickly produce excellent three-dimensional color photographic slides or prints from the color photographic material.

A fourth object of the present invention is to provide a silver halide light-sensitive material that provides not only a three-dimensional effect but also a more powerful impression, and a method for forming a three-dimensional color photographic image.

Other objects will be apparent from the description.

(Means for Solving the Problems) The above object of the present invention is to provide a magenta coloring silver halide photosensitive layer (referred to as ML), a cyan coloring silver halide photosensitive layer (referred to as CL), a yellow coloring silver halide photosensitive layer (referred to as CL), and a yellow coloring silver halide photosensitive layer on a support. In a silver halide color light-sensitive material for stereophotography having a layer (referred to as YL) and an intermediate layer (IL), the following general formula [

Furthermore, it has been found that the objects of the present invention can be achieved by the following silver halide color photosensitive material for stereophotography and the image forming method for stereophotography.

That is, (2) ML and CL on the back surface of a sheet having a substantially repeated structure of lenticules on the surface of a transparent substrate.

In the literature regarding conventional silver halide photosensitive materials, there is no mention of improvements in the elements of silver halide photosensitive materials that play a central role in improving the image quality or stereoscopic effect of stereoscopic photographs.However, the present inventors have made various efforts. As a result of our investigation, we found that the materials and additives used in silver halide photosensitive materials play a central role in producing 3D color photographs with excellent 3D effect, and in particular, the pyrazoloazole couplers contained in the photosensitive materials. The inventors have discovered that the saturation of a color image derived from the above surprisingly contributes significantly to the three-dimensional effect, leading to the present invention.

In the stereoscopic photograph according to the present invention, if the saturation of the reddish to yellowish color image is increased among the colors of black, blue, or edge threads,
This is presumed to be because the red or yellow color image is closer to the eye than the eye, and the perspective of the image is emphasized when observed.

Furthermore, in the past, expensive equipment such as a special stereo camera had to be used to obtain stereoscopic images, and the quality of the stereoscopic photographs obtained was not satisfactory. However, by using the light-sensitive material for stereoscopic photography of the present invention, the image quality and stereoscopic effect of the obtained stereoscopic photographs are improved, so even if the image is taken more simply and easily than before, it can still produce a sufficiently satisfying three-dimensional effect. It has become possible to obtain high-quality stereoscopic photographs.

The present invention will be explained in more detail.

Further, the silver halide color light-sensitive material for stereophotography of the present invention preferably contains a compound represented by the above-mentioned formula CI) in the intermediate layer (IL).

A color mixing inhibitor is used in the intermediate layer (IL), preferably a pyrazoloazole-based magenta coupler represented by the general formula CM), which is close to the photosensitive layer, to create a magenta color image after processing. It is presumed that by preventing this from occurring, the saturation of the red color image is further increased, and the three-dimensional effect is further enhanced.

For the purpose of simply preventing color mixture, hydroquinone derivatives, aminophenol derivatives, amines, gallic acid derivatives, catechol derivatives, ascorbic acid derivatives, colorless couplers, sulfonamidophenol derivatives, and the like may be used. However, as a result of various studies, it has been found that the use of a compound represented by the following general formula (1) as a color mixing inhibitor is effective in improving color image forming ability (coloring efficiency and maximum coloring density), causing capri and staining, and inducing black and white development. It has been found that this is preferable because it does not induce defects such as acceleration and fading of color images.

In a three-dimensional photographic print having a lenticule sheet, if the thickness of the film is thick, the focus of light passing through the lenticule sheet will be out of focus, resulting in poor image sharpness.

However, in the present invention, by using the compound represented by the general formula (1), even a thin layer can sufficiently prevent color mixing and provide good sharpness.

When the film thickness of the IL close to the GL is increased, for example, to 1.54 or more, color mixture tends to be reduced. However, in the present invention, GL, RL and BL are close to each other, for example, the thickness of these intermediate layers is 81! m or less, preferably in the range of 7 to 4 in order to further enhance the three-dimensional effect.

The compound represented by formula (1) of the present invention causes color mixture (color fog)
It has excellent prevention performance and has little side effects such as formation of colored substances, fogging, changes in sensitivity, and fading of color images during storage, during or after development.

Moreover, it is effective even when added in a small amount, and can be made into a thin layer.

In the present invention, in order to obtain a more three-dimensional image, it is effective to increase the saturation (degree of saturation) of a red color image. By joining, the brightness (sensory attribute) of red to yellow color images can be increased relative to other color images such as blue and green, thereby creating an amazing three-dimensional effect, or rather It was found that it was possible to create a ``feeling of force''.

This powerful feeling is thought to be achieved by making colored images, especially yellow to magenta colored images, transparent, and by viewing stereoscopic photographs as transparent or translucent positive images. However, it is difficult to use this method for viewing stereoscopic reflection images.

Although it is possible to use both a transparent positive image and a reflective positive image as a translucent reflective positive image, only a halfway three-dimensional effect can be obtained.

Particularly preferably, gelatin is used as the hydrophilic colloid, and the gelatin is so-called lime-treated gelatin, acid-treated gelatin, enzyme-treated gelatin, or the like. For rapid processing, it is particularly preferable to use a compound having a narrow molecular weight distribution.

The molecular weight distribution of gelatin can be measured by GPC method (Gelvermini-silane chromatography). Gelatin in which the proportion of high molecular weight components is 122 weight % or more, preferably 14 weight % or more is preferred.
The GPC method is described in the main text and Example-1 of JP-A-62-87952.

The purpose of these compounds can be achieved by co-emulsifying them with a coupler and adding them to the photosensitive layer, usually in an amount of 5 to 100% by weight based on the corresponding color coupler. In order to prevent the cyan dye image from deteriorating due to heat and especially light, it is more effective to introduce an ultraviolet absorber into the cyan coloring layer and the layers on both sides adjacent to it.

As ultraviolet absorbers, benzotriazole compounds substituted with aryl groups (for example, U.S. Pat. No. 3,533,7
94), 4-thiazolidone compounds (e.g., U.S. Pat. No. 3,314,794, U.S. Pat. No. 3,352.
681), benzophenone compounds (e.g., those described in JP-A No. 46-2784), cinnamic acid ester compounds (e.g., as described in U.S. Pat. ), butadiene compounds (as described in U.S. Pat. No. 4,045,229), or benzoxadole compounds (for example, as described in U.S. Pat. No. 3,406,070, U.S. Pat. 271.307) can be used. Ultraviolet absorbing couplers (for example, α-naphthol cyan dye-forming couplers), ultraviolet absorbing polymers, and the like may be used, and these ultraviolet absorbers may be mordanted in specific layers.

Among these, benzotriazole compounds substituted with the aforementioned aryl group are preferred.

In addition, it is particularly preferable to use the following compounds together with the couplers described above, particularly in combination with pyrazoloazole couplers.

That is, a compound (F) that chemically bonds with the aromatic amine developing agent remaining after color development processing to produce a chemically inert and substantially colorless compound and/or an aroma remaining after color development processing. For example, in storage after processing, the compound (G) that chemically bonds with the oxidized form of a group amine color developing agent to produce a chemically inert and substantially colorless compound may be used simultaneously or singly. This is preferable in order to prevent staining and other side effects caused by the formation of coloring dyes due to the reaction between the color developing agent or its oxidized product remaining in the film and the coupler.

A preferred compound (F) has a second-order reaction rate constant kg (in trioctyl phosphate at 80°C) with p-anisidine of 1. Of/mol-see ~I X1
It is a compound that reacts in the range of 0-'ffi/■01·see.

Incidentally, the second-order reaction rate constant can be measured by the method described in JP-A-63-158545.

If R2 is larger than this range, the compound itself becomes unstable and may react with gelatin or water and decompose. On the other hand, if R2 is smaller than this range, the reaction with the remaining aromatic amine developing agent will be slow, and as a result, side effects of the remaining aromatic amine developing agent may not be prevented.

A more preferable compound (F) can be represented by the following formula (Fl) or (Fll).

General formula (Fl) R1-(A), -X General formula (Fir) R1-C=V In the formula, R3 and R1 each represent an aliphatic group, an aromatic group, or a heterocyclic group, and n is 1 Or represents 0.

A represents a group that reacts with an aromatic amine developer to form a chemical bond, X represents a group that reacts with an aromatic amine developer and leaves, B represents a hydrogen atom, an aliphatic group, an aromatic group group, heterocyclic group, acyl group, or sulfonyl group,
Y represents a group that promotes the addition of an aromatic amine developing agent to the compound of general formula (Fn), where R1 and X, Y and R2 or B are bonded to each other to form a cyclic structure. It's okay.

Among the methods of chemically bonding with the residual aromatic amine developing agent, the typical ones are substitution reaction and addition reaction.

The photosensitive material produced using the present invention contains a water-soluble dye or a dye that becomes water-soluble through photographic processing, as a filter dye in the hydrophilic colloid layer, or for various purposes such as preventing radiation staining and halide staining. Such dyes which may be used include oxonol dyes, hemioxonol dyes, styryl dyes, merocyanine dyes, cyanine dyes and azo dyes. Among them, oxonol dyes, hemioxonol dyes and merocyanine dyes are useful.

As the binder or protective colloid that can be used in the emulsion layer of the light-sensitive material of the present invention, it is advantageous to use gelatin, but other hydrophilic colloids can be used alone or together with gelatin.

In the present invention, the gelatin may be either lime-treated or acid-treated.Details of the gelatin manufacturing method can be found in The Macromolecule Chemistry on Gelatin, written by Arthur Vuis. Published by Academic Press, 1964).

As the transparent support used in the present invention, transparent films such as cellulose nitrate film and polyethylene terephthalate, which are usually used in photographic materials, can be used.

The "reflective support" used in the present invention is one that enhances the reflectivity and makes the dye image formed in the silver halide emulsion layer clearer. Includes those coated with a hydrophobic resin containing a dispersed light-reflecting substance such as titanium oxide, zinc oxide, calcium carbonate, and calcium sulfate, and those using a hydrophobic resin containing a dispersed light-reflecting substance as a support6. For example, baryta paper, polyethylene-coated paper, polypropylene synthetic paper, transparent supports with a reflective layer or a reflective material, such as glass plates, polyester films such as polyethylene terephthalate, cellulose triacetate or cellulose nitrate, polyamide film, polycarbonate film,
Examples include polystyrene film and vinyl chloride resin.

As other reflective supports, supports having a specular reflective or second type diffuse reflective metal surface can be used. The metal surface has a spectral reflectance of 0.5 in the visible wavelength range.
The above is preferable, and it is also preferable to roughen the metal surface or use metal powder to make it diffusely reflective.The metal should be aluminum, tin, silver, magnesium, or an alloy thereof, and the surface should be rolled. It may be the surface of a metal plate, metal foil, or thin metal layer obtained by , vapor deposition, plating, or the like.

Among these, it is preferable to obtain the metal by vapor deposition on another substrate.It is preferable to provide a layer of water-resistant resin, especially a thermoplastic resin, on the metal surface.8. For details of such a support, which is preferably provided with an antistatic layer on the opposite side, see, for example, JP-A-61-210.
No. 346, No. 63-24247, No. 63-24251
No. 63-24255, etc.

These supports can be appropriately selected depending on the purpose of use.

As a light-reflecting substance, it is best to thoroughly knead a white pigment in the presence of a surfactant, and also coat the surface of the pigment particles with
It is preferable to use one treated with a tetrahydric alcohol.

The occupied area ratio (%) of white pigment fine particles per determined unit area is most typically determined by dividing the observed area into 6-×6- adjacent unit areas and dividing the unit area into It can be determined by measuring the occupied area ratio (%) CR4) of the projected fine particles. The coefficient of variation of the occupied area ratio (%) is the ratio of the standard deviation S of R1 to the average value (R) of R, s
/R can be obtained. The number (n) of target unit areas is preferably 6 or more, and therefore the coefficient of variation S/π can be determined by.

In the present invention, the variation coefficient of the occupied area ratio (%) of pigment fine particles is preferably 0.15 or less, particularly 0.12 or less. If it is 0.08 or less, the dispersibility of the particles is substantially "uniform". It can be said that.

(Left below) In addition, in order to further improve the 3D image quality, the printing process related to the spectral sensitivity distribution of the original film obtained from the color photosensitive material for photography and the color photosensitive material for printing is performed as a system for each exposure of the color photosensitive material for printing. It is preferred to reduce the exposure color mixing degree (β) or the average color mixing degree (r) for the layer, especially for GL, these to at least 2! The spectral transmittance and printing of the color image of the original film obtained by photographing using a photosensitive material packaging unit with a lens depends on the spectral energy distribution of the light source and the distribution and sensitivity distribution of the photosensitive layer of the color photosensitive material for printing.

The degree of color mixing (β) or the average degree of color mixing (r) in printing can be determined, for example, by the method described in European Patent EP 295,716^2. For example, a Macbeth color chart consisting of 18 chromatic colors and 6 achromatic colors, which is generally used to evaluate color reproducibility, is used for the subject of color photosensitive materials for photography.
(J, Appl, Phot, Eng.) Volume 2, 95-991 (1976 edition).

Ti (λ) is the spectral transmittance distribution of the color and negative color materials obtained by photographing Macbeth color chart i, and S (λ) is the spectral sensitivity distribution of the green sensitive layer (GL) of the color print photosensitive material.
When the energy distribution of the printing light source is P (λ), the amount of exposure received by the green sensitive layer (GL) is expressed by the following formula (1) for color chart i. , since medium-density achromatic colors are printed to a certain density on the print, the standard is achromatic color char) (i is 22
, the optical density is approximately 0.7), and the exposure amount Egz of the other chart is determined as 1.0. i
It can be expressed whether the exposure amount Ei of the color is large or small.

Hi=Ei/E, laziness -・-・・・0) Spectral spectrum of delta function form that has a sensitivity of 5n- width centered on the main maximum sensitivity wavelength of the green sensitive layer (CL) as its ideal spectral sensitivity distribution. When the sensitivity distribution is set and its Hi is set as Hi., α defined by the following equation (3) represents the magnitude of deviation from the ideal exposure amount of the color of chart i.

cr i -Hi / Hi'---(3
) Therefore, the degree of color mixture βi of the colors of chart i can be defined as shown in the following equation (4).

βi=αi -1,0-- It can be defined as the average color mixing degree T of the green sensitive layer.

The average color mixing degree of the blue sensitive layer (BL) and red sensitive layer (RL) also has an effective wavelength range of 390rv+~500nm and 570ns, respectively.
~740n- is similarly defined and can be easily determined.

In the present invention, a green-sensitive silver halide photosensitive layer (GL)
The average degree of color mixing is preferably 0.13 or less, preferably 0.1O or less.

The color photographic material of the present invention is preferably subjected to color development, bleach-fixing, and water-washing treatment (or stabilization treatment). Bleaching and fixing may be performed separately instead of in one bath as described above. .

The color developer used in the present invention contains a known aromatic primary amine color developing agent.

Preferred examples are p-phenylenediamine derivatives, representative examples of which are shown below, but are not limited thereto.

methanesulfonamido)ethyltoaniline (exemplified compound D-6).

Furthermore, these p-phenylenediamine derivatives may be salts such as sulfate, hydrochloride, sulfite, and P-)luenesulfonate. Preferably from about 0.1 g to about 20 g per IIl
g1, more preferably a concentration of about 0.5 g to about 10 g.

In carrying out the present invention, it is preferable to use a developer that does not substantially contain benzyl alcohol. Here, "substantially free" means preferably 2M1/l or less, more preferably 0.5M1/l or less, and more preferably 0.5M1/l or less. benzyl alcohol concentration, most preferably containing no benzyl alcohol.

It is more preferable that the developer used in the present invention does not substantially contain sulfite ions.Sulfite ions function as a preservative for the developing agent, and at the same time have a silver halide dissolving action and react with the oxidized developing agent. However, it has the effect of reducing pigment formation efficiency.

Such an effect is presumed to be one of the causes of increased fluctuations in photographic characteristics due to continuous processing. Here, "substantially not containing" preferably means a sulfite ion concentration of 3.0 x 10 -' mol/l or less, and most preferably no sulfite ion at all.

However, in the present invention, a very small amount of sulfite ion used to prevent oxidation in a processing agent kit in which the developing agent is concentrated before being mixed into a solution for use is excluded.

The developer used in the present invention preferably does not substantially contain sulfite ions, and more preferably does not substantially contain hydroxylamine. This is because hydroxylamine functions as a preservative in the developer. At the same time, it has silver developing activity itself, and it is thought that fluctuations in the concentration of hydroxylamine greatly affect photographic properties.

The expression "substantially not containing hydroxylamine" as used herein means preferably a hydroxylamine concentration of 5.0 x 10-'' mol/It or less, and most preferably no hydroxylamine at all.

It is more preferable that the developer used in the present invention contains an organic preservative instead of the hydroxylamine or sulfite ion.

Here, the term "organic preservative" refers to any organic compound that reduces the rate of deterioration of aromatic primary amine color developing agents when added to the processing solution for color photographic light-sensitive materials, such as air in color developing agents. Among them, hydroxylamine derivatives (excluding hydroxylamine, the same shall apply hereinafter), hydroxamic acids, hydrazines, hydrazides, phenols, α-hydroxyketones, α- Particularly effective organic preservatives include aminoketones, sugars, monoamines, diamines, polyamines, quaternary ammonium salts, nitroxy radicals, alcohols, oximes, diamide compounds, and fused cyclic amines. .

After desilvering treatment such as fixing or bleach-fixing, washing with water and/or stabilization treatment is generally performed.

The amount of water used in the washing process varies widely depending on the characteristics of the photosensitive material (for example, depending on the materials used such as couplers), the purpose, the temperature of the washing water, the number of washing tanks (number of stages), the replenishment method such as countercurrent or forward flow, and various other conditions. Can be set. Among these, the relationship between the number of flushing tanks and the amount of water in the multistage countercurrent method is described in the Journal on the Society on Motion Picture and Television Engineers.
nalof the 5ociety of Moti

n Engineers) Volume 64, p, 248-25
3 (May 1955 issue).

Generally, the number of stages in the multistage countercurrent system is preferably 2 to 6, particularly preferably 2 to 4.

According to the multistage countercurrent method, the amount of washing water can be greatly reduced, for example, to 0.51 to 12 or less per 1nf of photosensitive material, and the effect of the present invention is remarkable. As the time increases, problems arise such as bacteria propagating and resulting floating matter adhering to the photosensitive material. As a solution to such problems, the method of reducing calcium and magnesium described in JP-A-62-288838 can be used very effectively. Also, JP-A-57-8

The fungicides described in Dictionary of Antibacterial and Antifungal Agents J (1986) can also be used.

Further, in the washing water, a surfactant can be used as a draining agent, and a chelate such as EDTA can be used as a water softener.

The above-mentioned water washing step can be followed or the stabilizing solution can be directly treated without going through the water washing step. A compound having an image stabilizing function is added to the stabilizing liquid, such as an aldehyde compound such as formalin, or a film suitable for stabilizing the dye.
Examples include buffers for preparing H and ammonium compounds. Further, in order to prevent the proliferation of bacteria in the liquid and to impart anti-mold properties to the photographic material after processing, the various disinfectants and anti-mold agents described above can be used.

Furthermore, a surfactant, a fluorescent whitening agent, and a hardening film may be added. In the processing of the photosensitive material of the present invention, when stabilization is directly performed without going through a water washing step, JP-A-57-

In addition, it is also a preferable embodiment to use chelates such as 1-hydroxyethylidene-1,1-diphosphonic acid and ethylenediaminetemethylenephosphonic acid, and magnesium and bismuth compounds.

A so-called rinsing solution is also used as a washing solution or stabilizing solution used after desilvering treatment.

The preferred pH of the water washing step or stabilization step is 4 to 10, more preferably 5 to 8. The temperature can be set in various ways depending on the use and characteristics of the photosensitive material, but generally it is 15 to 45°C.
The zero time, which is preferably 20 to 40°C, can be set arbitrarily, but a shorter time is desirable from the viewpoint of reducing processing time, preferably 15 seconds to 1 minute 45 seconds, more preferably 30 seconds to 1 minute.
It is minute 30 seconds. The smaller the amount of replenishment, the better from the viewpoints of running costs, reduced emissions, ease of handling, and the like.

A specific preferable replenishment amount is 0.5 to 50 times, preferably 3 to 40 times, the amount brought in from the previous bath per unit area of the photosensitive material. Or, it is 12 or less, preferably 500 d or less per photosensitive material. Further, replenishment may be performed continuously or intermittently.

The liquid used in the water washing and/or stabilization step can also be used in the previous step. An example of this is to reduce the amount of waste liquid by using a multi-stage counter-current system to allow the overflow of the wash water to flow into the bleach-fix bath, which is a pre-bath, and to replenish the bleach-fix bath with concentrated liquid.

The chroma of the sample using the magenta coupler of the formula [M] of the present invention is significantly higher than that of the sample using the conventionally used 5-pyrazolone magenta coupler. At the same time, it can be seen that the three-dimensional effect is also significantly enhanced. And these effects can be achieved by using W as a reflective support.
Rather than using supports such as P-1 and WP2, WP-
It can be seen that more remarkable results can be obtained by using a support such as No. 3 or WP-4, especially WP-4.

Furthermore, from a comparison of the spectral characteristics of the magenta coloring dye shown in Table 2 and the results in Table 7, it is clear that in order to enhance the three-dimensional effect, the spectral absorption characteristic curve of the magenta coloring dye must be low. 1 value and -. , 1 no. It can be seen that it is better to use a magenta coupler that gives a value of .
