Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a silver halide photosensitive material housed in a cartridge.

(Prior art) Conventional cartridges for silver halide photographic materials include so-called instamatic 126-size cartridges with a screen size of 2.8CIX2.85CID (standard content is ANSI/ASCPH1,4O-1984).
) and 1.3cm x 1.1aa so-called pocket-sized 110 size cartridge (ANSI/ASCPH
1, 55-1986) have been used. It is true that these cartridges have the advantages of being easy to load into the camera, less likely to malfunction, no need to wind the film when taking it out after shooting, and easy to take out and reload the film in the middle of shadowing. Although the ratio has increased, the usage ratio has been decreasing recently due to reasons such as the small screen size and poor image quality when printing, and the aspect ratio of prints being close to 1.0, making it difficult to see the prints.

Recently, disposable photosensitive material cartridges such as Utsurun desu and Utsurun desu HiJ have become popular, but because they are disposable, they have the problem of being expensive per frame. Ta.

On the other hand, the tabular silver halide emulsion of the present invention is known to be used in ordinary halide m-sensitive materials, but when these are housed in 110 size or 126 size, the screen size is small and the magnification rate is low. Because they are large, their graininess is noticeable, they tend to blur when printed, making it difficult to obtain good sharpness, and the aspect ratio of the screen is unfavorable, causing psychological and physiological anxiety. .

Also, the so-called 135 size 135 patrone and 120
With the size of the Brawny, there were problems with maneuverability such as loading and reeling.

Therefore, there has been a need for a photosensitive material for cartridges that is easy to handle, has high image quality, and is inexpensive.

(Problems to be Solved by the Invention) The purpose of the present invention is, firstly, to provide a photosensitive material housed in a cartridge for producing prints with excellent n-removal properties, and secondly, to Thirdly, it is necessary to supply such a photosensitive material that has a suitable screen size that does not cause blurring during printing, and fourthly, it is easy to handle. The fifth objective is to supply such a photosensitive material that the camera is not disposable and the price per frame is low.

(Means for Solving the Problems) These objects of the present invention have been achieved by the following color photographic material.

A silver halide photographic light-sensitive material stored in a cartridge contains at least one emulsion consisting of tabular halide grains having an average aspect ratio of 5 or more, and the cartridge carries a roll-shaped unexposed light-sensitive material. It consists of a roll chamber for storing, a winding chamber for winding up the exposed photosensitive material, and a bridge section that connects them and has an opening, and furthermore, the effective screen area per frame exposed to the photosensitive material at the opening is 3.0cd or more 25゜M

The cartridge of the present invention comprises a film roll chamber for storing a roll of unexposed photosensitive material, a winding chamber for winding up the exposed photosensitive material, and a bridge section connecting them and having an opening. The moving image area per frame exposed on the photosensitive material is 3. 0cti
25.0C11 or less, and the ratio of the length of the long side to the length of the short side of one frame of screen (aspect ratio) is 1.2
2.0 or less.

Preferred effective screen area is 6.0cd or more 16°0CT
1 or less, particularly preferably 8.0 cd or more IO,O
cJ or less. If the effective screen area is too small, graininess,
Image quality such as sharpness becomes less acceptable to users. If the effective screen area is too large, the size of the camera will increase, making it even harder for users to easily enjoy taking photos anytime and anywhere.

A preferred aspect ratio is 1. It is 3 or more and 1.7 or less. The generally preferred aspect ratio is the golden section (1,6
), but the optimal aspect ratio for photographic prints was determined based on monitor tests conducted on touch users.

In particular, the service system for the current 135-format color negative/vapor lab system is extremely complete.
It is highly desirable for the user to select a screen size and film width that are compatible with the system.

A preferred film width is 35±1 m/m, particularly preferably 35±0.5 m/m.

In the conventional cartridge of this type,
It has been common knowledge to use light-shielding paper as disclosed in Japanese Patent Nos. 4406 and 40-17829. However, the presence of light-shielding paper is undesirable because it causes deterioration of the flatness of the film at the exposure aperture, making it difficult to obtain sharply focused photographs, and reducing the effect of increasing the screen size by half, so the light-shielding paper is removed. However, it is preferable to employ another light shielding means, and specific examples of the light shielding means are illustrated below.

Regarding the tabular silver halide emulsion in the present invention.

I will explain.

A preferred embodiment of the light-sensitive material of the present invention uses at least one red-sensitive emulsion layer, one green-sensitive emulsion layer, and one blue-sensitive emulsion layer on a support, and at least one of these emulsion layers has an average aspect ratio of at least one. It contains a silver halide emulsion consisting of 5 or more tabular silver halide grains.

In the photosensitive silver halide emulsion, 70% or more of the total projected area of the silver halide grains is tabular grains having a diameter of 0.times.15 .mu.m or more, and the average aspect ratio of the tabular grains is 5 or more.

The tabular grain herein is a general term for grains having one twin plane or two or more parallel twin planes. In this case, the twin plane refers to the (1,1,1) plane when the ions at all lattice points on both sides of the (1,1,■) plane have a mirror image relationship.

These tabular grains have a triangular, hexagonal, or rounded circular shape when viewed from above.
Triangular shaped ones have triangular shaped ones, hexagonal shaped ones have hexagonal shaped outer surfaces, and circular shaped ones have mutually parallel outer surfaces.

The average aspect ratio of tabular grains in the present invention is 0.
This is the average value of the diameter divided by the thickness of tabular grains having a major diameter of 15μ or more.

In the present invention, the grain diameter of a tabular grain is the diameter of a circle having an area equal to the projected area of the parallel outer surface of the grain.

The projected area of particles is determined by measuring the area on an electron micrograph.
It is obtained by correcting the projection magnification.

The thickness of the particles is measured by depositing metal along with latex as a reference from an oblique direction on the particles, measuring the length of the shadow on an electron micrograph, and calculating using the length of the latex shadow as a reference. It's easy to do.

In the present invention, 80% of the total projected area of silver halide grains is
It is preferred that at least %, particularly at least 90%, be tabular grains with a diameter of 0.15 μm or more.

The diameter of the tabular grains is preferably from 0.15 to 5.0 .mu.m, more preferably from 0.20 to 2.0 .mu.m, particularly from 0.25 to 1.degree. 2 .mu.m.

The thickness of the tabular grains is preferably 0.05 to 1.0 .mu.m, particularly 0.1 to 0.5 .mu.m, and more preferably 0.1 to 0.3 .mu.m.

The photographic emulsion of the present invention may contain any silver halide including silver bromide, silver iodobromide, silver iodochloride, silver chlorobromide and silver chloride.

The photographic emulsion of the present invention may have a layered structure of at least two substantially different halogen compositions within the silver halide grains, or may have a uniform composition.

In emulsions with layered structures with different halogen compositions,
The emulsion may include a high iodine layer in the core and a low iodine layer in the outermost layer, or an emulsion including a low iodine layer in the core and a high iodine layer in the outermost layer, and the layered structure may be composed of three or more layers. The iodine may be lower or higher as the iodine is located on the outer side.

In the silver halide of the present invention, a conversion method may be used at any stage of formation to change the halogen composition of the grains.

Known silver halide solvents such as ammonia, thioether, and urea can be present during the growth of the silver halide grains of the present invention.

The silver halide grains of the present invention can be produced by cadmium salt, zinc salt, lead salt, thallium salt, iridium salt (including lead salt), rhodium salt (including lead salt) in the process of forming and/or growing the grain. ) and iron salts (including lead salts) to contain these metal elements inside the particles and/or on the surface of the particles. By placing it in an atmosphere, reduction sensitization can be applied to the inside of the particle and/or the surface of the particle.

In the silver halide emulsion of the present invention, unnecessary soluble salts may be removed after the growth of silver halide grains is completed, or they may remain contained. When removing the salts, please refer to Research Disc.
Disclosure (hereinafter abbreviated as RD) No. 1764 ■
It can be carried out based on the method described in Section.

The silver halide emulsion of the present invention can be chemically sensitized by conventional methods. That is, a sulfur sensitization method, a selenium sensitization method, a reduction sensitization method, a noble metal sensitization method using gold or other noble metal compounds, etc. can be used alone or in combination.

The emulsion of the present invention can be prepared by the following precipitation method. The dispersion medium is placed in a conventional silver halide precipitation reactor equipped with a stirring mechanism.

Typically, the amount of dispersion medium introduced into the reactor in the initial stage is at least about 10%, preferably from 20 to 80%, of the amount of dispersion medium present in the silver iodobromide emulsion during the final grain precipitation stage. The dispersion medium initially introduced into the reactor is water or a dispersion medium of a peptizer in water, which is optionally combined with other components such as one or more silver halide ripeners and /or A metal dopant, which will be detailed later, is added.

If a peptizer is initially present, its concentration is preferably at least 10%, especially at least 20%, of the total amount of peptizer present in the final stage of silver iodobromide precipitate formation, together with silver and halide salts. Additional dispersion medium is added into the reactor, which can be introduced from a separate jet. Generally, the proportion of dispersion medium is adjusted after the halide salt introduction is completed, especially to increase the proportion of peptizer.

Usually 10 bromide salts used for producing silver iodobromide grains
Less than % by weight is initially present in the reactor to provide a concentration of bromide ions in the dispersion medium at the beginning of silver iodobromide precipitation formation. Further, the dispersion medium in the reaction vessel initially does not substantially contain iodide ions. This is because the presence of iodide ions before the simultaneous addition of silver and bromide salt tends to produce thick non-tabular grains.

Here, "substantially free of iodide ions" means that iodide ions are present in insufficient amounts to precipitate as a separate silver iodide phase compared to bromide ions. The iodine concentration in the reactor before introducing the silver salt is 0.5 mol% of the total halide ion concentration in the reactor.
If the pBr of the dispersion medium is initially too high, which is preferably maintained at less than 0, the tabular silver iodobromide grains produced will be relatively thick and the grain thickness distribution will be wide. Also, the number of non-tabular grains increases. On the other hand, if the pBr is too low, non-tabular grains are likely to be formed.As a result of observing and examining the twin plane spacing of the tabular silver iodobromide grains, the pBr in the reaction vessel is 0.6 or more and less than 2.0, Preferably 1.1 or more and 1.8
It has been found that by maintaining the thickness below the range, the thickness distribution becomes narrower.

The pBr used here is defined as the negative value of the logarithm of the bromide ion concentration.

During the precipitation, silver, bromide, and iodide salts are added to the reactor according to techniques well known for the precipitation of silver iodobromide grains. A soluble radical such as silver nitrate is usually added to the reactor at the same time as the introduction of the bromide and iodo salts. Introduce an aqueous solution of salt. Bromide and iodo salts may also be introduced as aqueous salt solutions, such as aqueous solutions of soluble ammonium, alkali metal (eg, sodium or potassium) or alkaline earth metal (eg, magnesium, or calcium) halide salts. The silver salt, at least initially, is introduced into the reactor separately from the bromide salt and the iodo salt. The bromide salt and iodo salt may be added separately or may be introduced as a mixture.

Introducing the silver salt into the reaction vessel initiates the particle nucleation step. Continued introduction of silver, bromide, and iodide salts forms a population of grain nuclei that serve as sites for silver bromide and silver iodide precipitation. The grains enter the growth stage due to the precipitation of silver bromide and silver iodide on the existing grain cores. Before entering the 0-grain growth stage, the average value of the circular equivalent diameter of the projected area of tabular grains is 0.6μ or less. The nucleation conditions are preferably 0.4μ or less, and the method described in Japanese Patent Application No. 61-48950 can be referred to, but the method is not limited to this method. For example, the nucleation temperature can be in the range of 5 to 55°C.

The size distribution of the tabular grains formed according to the present invention is:
It is strongly influenced by the bromide and iodide salt concentrations during the growth stage. If pBr is too low, tabular grains with a high aspect ratio are formed, but the coefficient of variation of the projected area becomes significantly large. pB' about 2.2-5, preferably Mi2
．． By maintaining the ratio between 5 and 4, tabular grains with a small coefficient of variation in projected area can be formed.

Silver, provided that the pBr conditions described above are satisfied.
The concentration and rate of introduction of bromide and iodo salts may be similar to those conventionally used. Silver and halide salts are preferably introduced at a concentration of 0.1 to 5 moles per liter; A wider concentration range can be employed, for example from o, oi moles per liter to saturation. A particularly preferred precipitation technique is to increase the rate of silver and halide salt introduction to reduce precipitation time. The rate of introduction of silver and halide salts can be increased by increasing the rate of introduction of the dispersion medium and the silver and halide salts, or by increasing the concentration of silver and halide salts in the dispersion medium being introduced. . The coefficient of variation in the projected area of particles can be further reduced by maintaining the addition rate of the salt and halide salt near the limit value at which new particle nuclei are generated, as described in JP-A-55-142329. .

In order to make the thickness uniform, in addition to selecting the pBr temperature at the nucleation and grain growth stages as described above, the following must also be taken into consideration.

The amount of gelatin in the reaction vessel during nucleation greatly influences the particle size distribution. If the amount of gelatin is not optimally selected, nucleation will be non-uniform, and when twin planes are observed using the method described above, b/a will vary greatly between particles, and the gelatin concentration will be 0.5 to 10 wt%. is preferable, and more preferably 0.5 to 6 wt%.

In addition, the stirring rotation speed and the shape of the reaction vessel also affect the particle size distribution and b/a distribution.

As the stirring/mixing device, a device that adds and mixes a reaction liquid into the liquid as described in US Pat. No. 3,785,777 is preferable, and the stirring rotation speed may not be too low or too high. If the stirring rotation speed is low, the generation rate of non-parallel twin grains will increase, and if it is too high, the frequency of generation of tabular grains will decrease and the size distribution will become wider.

The most preferable shape of the reaction vessel is one in which the bottom is a semicircle.

The light-sensitive material of the present invention only needs to have at least one silver halide emulsion layer of a blue-sensitive layer, a green-sensitive layer, and a red-sensitive layer on the support. There are no particular limitations on the number of layers and non-photosensitive layers and the layer 111. A typical example is a silver halide photographic light-sensitive material having on a support at least one photosensitive layer consisting of a plurality of silver halide emulsion layers having substantially the same color sensitivity but different photosensitivity. The photosensitive layer is a unit photosensitive layer that is sensitive to blue light, green light, or red light, and in a multilayer silver halide color photographic light-sensitive material, generally the unit photosensitive layer is The arrangement is, in order from the support side, a red sensitive layer,
A green sensitive layer and a blue sensitive layer are installed in this order. However, depending on the purpose, the order of installation may be reversed, or the order of installation may be such that different photosensitive layers are sandwiched between the same color-sensitive layer.

Non-photosensitive layers such as various intermediate layers may be provided between the silver halide photosensitive layers and between the uppermost layer and the lowermost layer.

The intermediate layer includes JP-A Nos. 61-43748 and 59-1.
No. 13438, No. 59-113440, No. 61-20
Coupler, DIR compound, etc. as described in No. 037 and No. 61-20038 may be included,
It may also contain a commonly used color mixing inhibitor.

A plurality of silver halide emulsion layers constituting each unit photosensitive layer are composed of a high-speed emulsion layer and a low-speed emulsion layer, as described in West German Patent No. 1,121,470 or British Patent No. 923,045. A two-layer configuration can be preferably used.

Usually, it is preferable to arrange the layers so that the photosensitivity decreases toward the support, and a non-photosensitive layer may be provided between each halogen emulsion layer. Also, JP-A No. 571
No. 12751, No. 62-200350, No. 62-20
As described in No. 6541, No. 62-206543, etc., a low-sensitivity emulsion layer may be provided on the side far from the support, and a high-sensitivity emulsion layer may be provided on the side close to the support.

As a specific example, from the side farthest from the support, low sensitivity blue sensitive layer (BL) / high sensitivity blue sensitive layer (BH) / high sensitivity green sensitive layer (C, H) / low sensitivity green sensitive layer ( (L)/high-sensitivity red-sensitive layer (RH)/low-sensitivity blue-sensitive layer (RL),
Further, they can be installed in the order of BH/BL/GL/GH/RH/RL, or in the order of BH/BL/C;H/GL/RL/RH.

They can also be arranged in the order of RH/G L/RL, or as described in JP-A Nos. 56-25738 and 62-63936, the blue-sensitive layer/ They can also be arranged in the order of GL/RL/C; H/RH.

In addition, as described in Japanese Patent Publication No. 49-15495, the upper layer is a silver halide emulsion layer with the highest sensitivity, the middle layer is a silver halide emulsion layer with lower sensitivity, and the lower layer is more sensitive than the middle layer. An example is an arrangement consisting of three layers having different photosensitivity, in which a silver halide emulsion layer with a low density is arranged, and the photosensitivity is decreased by about one order of magnitude toward the support. Even in the case where the layer is composed of three layers with different photosensitivity, as described in JP-A No. 59-202464, medium-sensitivity emulsion is added from the side remote from the support in the same color-sensitive layer. They may be arranged in the following order: layer/high-speed emulsion layer/low-speed emulsion layer.

In addition, high-sensitivity emulsion layer / low-sensitivity emulsion layer / medium-sensitivity emulsion layer,
Alternatively, they may be arranged in the order of low-speed emulsion layer/medium-speed emulsion layer/high-speed emulsion layer, etc.

Furthermore, even in the case of four or more layers, the arrangement may be changed as described above.

As mentioned above, various layer structures and arrangements can be selected depending on the purpose of each photosensitive material.

Further, the swelling rate is preferably 150 to 400%. The swelling rate can be calculated from the maximum swollen film thickness under the above-mentioned conditions according to the formula: (maximum swollen film thickness - film thickness)/film thickness.

Development processing can be carried out by the usual method described in 615 left column to right column of No. 18716.

The color developing solution used in the development of the light-sensitive material of the present invention is preferably an alkaline aqueous solution containing an aromatic primary amine color developing agent as a main component. Aminophenol compounds are also used as color developing agents, but p-phenylenediamine compounds are preferably used. Representative examples thereof include 3-methyl-4-amino-N, N-diethylaniline, 3-methyl -4-amino-H-ethyl-N-β
-Hydroxyethylaniline, 3-methyl-4,amino-N-ethyl-N-β-methanesulfonamidoethylaniline, 3-methyl-4-amino-N-ethyl-β-methoxyethylaniline and their sulfates, Examples include hydrochloride and ρ-toluenesulfonate. Among these, 3-methyl-4-amino-N-ethyl-N-β-hydroxyethylaniline sulfate is particularly preferred, and two or more of these compounds may be used in combination depending on the purpose.

The color developer may contain pH buffering agents such as alkali metal carbonates, borates or phosphates, chloride salts, bromide salts,
It is common to include development inhibitors or antifoggants such as iodide salts, benzimidazoles, benzothiazoles or mercapto compounds. If necessary, various preservatives such as hydroxylamine, diethylhydroxylamine, sulfites, hydrazines such as N,N-biscarboxymethylhydrazine, phenyl semicarbazides, triethanolamine, and catechol sulfonic acids, ethylene glycol, organic solvents such as diethylene glycol, development accelerators such as benzyl alcohol, polyethylene glycol, quaternary ammonium salts, amines, dye-forming couplers, competitive couplers, auxiliary developing agents such as 1-phenyl-3-pyrazolidone, viscosity Imparting agent, aminopolycarboxylic acid, aminopolyphosphonic acid,
Various chelating agents such as alkylphosphonic acids and phosphonocarboxylic acids, such as ethylenediaminetetraacetic acid, nitrilotriacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, hydroxyethyliminodiacetic acid, -hydroxyethylidene-1. 1-diphosphonic acid, nitrilo-N,N,N-1-rimethylenephosphonic acid, ethylenediamine-N,N,N,N-tetramethylenephosphonic acid, ethylenediamine-di(0-hydroxyphenylacetic acid) and their salts. This can be cited as a representative example.

Further, when performing reversal processing, black and white development is usually performed and then color development is performed. This black and white developer contains known black and white developing agents such as dihydroxybenzenes such as hydroquinone, 3-pyrazolidones such as 1-phenyl-3-pyrazolidone, or aminophenols such as N-methyl-p-aminophenol. Alternatively, they can be used in combination.

The pH of these color developing solutions and black and white developing solutions is preferably 9 to 12. The amount of replenishment of these developing solutions depends on the color photographic light-sensitive material to be processed, but it is 32 or less per square meter of -M light-sensitive material, and by reducing the bromide ion concentration in the replenisher, 500
It can also be less than d. When reducing the amount of replenishment, it is preferable to prevent evaporation of the liquid and air oxidation by reducing the area of contact with the air in the processing tank.

The contact area between the photographic processing solution and air in the processing tank can be expressed by the aperture ratio defined below.

That is, the above aperture ratio is preferably 0.1 or less, more preferably O, OQ1 to 0.05. As a method for reducing the aperture ratio in this way, in addition to providing a shield such as a floating lid on the surface of the photographic processing liquid in the processing tank,
Method using a movable lid described in No. 033, JP-A-63
The slit development processing method described in Japanese Patent No. 216050 can be mentioned. Reducing the aperture ratio is important not only for both color development and black and white development processes, but also for subsequent processes,
For example, it is preferable to apply it to all processes such as bleaching, bleach-fixing, fixing, washing, and stabilization, and it is also possible to reduce the amount of replenishment by using means to suppress the accumulation of bromide ions in the developer. .

The time for color development processing is usually set between 2 and 5 minutes, but the processing time can be further shortened by using a high temperature, high p)l, and a high concentration of color developing agent. .

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

The bleaching process may be carried out simultaneously with the fixing process (bleach-fixing process) or separately (bleach-fixing process), or in order to speed up the process, it may be carried out in two ways: bleach-fixing process after bleaching process. Depending on the purpose, treatment may be carried out in consecutive bleach-fixing baths, fixing treatment before bleach-fixing treatment, or bleaching treatment after bleach-fixing treatment. Examples of bleaching agents that can be used include compounds of polyvalent metals such as iron (Ill), peracids, quinones, nitro compounds, etc. Typical bleaching agents include salts of iron (I), such as Aminopolycarboxylic acids such as ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid to cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, 1,3-diaminopropanetetraacetic acid, glycol etherdiaminetetraacetic acid, or complex salts such as citric acid, tartaric acid, malic acid, etc. Can be used. Among these, aminopolycarboxylic acid iron (1[[) 11 salts, including ethylenediaminetetraacetate iron <III) complex salts and 1,3-diaminopropanetetraacetic acid iron ([)if salts] are used for rapid processing and prevention of environmental pollution. Preferable from the viewpoint of iron aminopolycarboxylate (
The II[) complex salt is particularly useful in both bleaching solutions and bleach-fixing solutions. These iron aminopolycarboxylic acids (
If) The pl+ of a bleach or bleach-fix solution using a complex salt is usually 4.0 to 8, but it can be processed at an even lower pt+ in order to speed up the processing.

A bleach accelerator may be used in the bleaching solution, bleach-fixing solution, and their prebaths, if necessary.

No. 8, West German Patent Tube No. 1.290,812, Japanese Patent Application Publication No. 1983-
Preferably, the compounds described in U.S. Pat. No. 95,630 are preferred, and the compounds described in U.S. Pat. These bleach accelerators are particularly effective when bleach-fixing materials.

In addition to the above-mentioned compounds, it is preferable that the bleaching solution and bleach-fixing solution contain an organic acid for the purpose of preventing bleach staining. Particularly preferred is 8! The acid is a compound having an acid dissociation constant (pKa) of 2 to 5, and specifically acetic acid, propionic acid, etc. are preferable.

Fixing agents used in fixing solutions and bleach-fixing solutions include thiosulfates, thiocyanates, thioether compounds, thioureas, large amounts of iodide salts, etc., but thiosulfates are generally used. Ammonium thiosulfate is the most widely used preservative for fixing solutions and bleach-fix solutions.
Sulfites, bisulfites, carbonyl sulfite adducts, and sulfinic acid compounds described in European Patent No. 294769A are preferred.Furthermore, various aminopolycarboxylic acids may be used in fixers and bleach-fixers for the purpose of stabilizing the solution. It is preferable to add organic phosphonic acids or organic phosphonic acids.

The total time for the desilvering process is preferably as short as possible without causing desilvering defects.The preferred time is 1 minute to 3 minutes, more preferably 1 minute to 2 minutes. In addition, the processing temperature is 25°C ~
50°C, preferably 35°C to 45°C. In a preferred temperature range, the desilvering rate is improved and the occurrence of staining after processing is effectively prevented.

In the desilvering process, stirring (preferably strengthened as much as possible; specific methods for strengthening stirring include:
JP-A-62-183460 and JP-A-62-183461 disclose a method of impinging a jet of processing liquid on the emulsion surface of a photosensitive material, and JP-A-62-183461 uses a rotating means to increase the stirring effect. Furthermore, there is a method of moving the photosensitive material while bringing the emulsion surface into contact with a wiper blade provided in the liquid to create turbulence on the emulsion surface, thereby improving the stirring effect, and increasing the circulation flow rate of the entire processing liquid. There are several methods. Such means for improving agitation is effective for all bleaching solutions, bleach-fixing solutions, and fixing solutions.

It is believed that improved stirring speeds up the supply of bleach and fixing agent into the emulsion film, and as a result increases the desilvering rate. Further, the agitation improving means described above is more effective when a bleach accelerator is used, and can significantly increase the accelerating effect and eliminate the fixing inhibiting effect caused by the bleach accelerator.

The automatic developing machine used for the photosensitive material of the present invention is
0-'191257, 5o-tc+xjsa, and 60-191259.
As described in No. 7, this type of conveyance means can significantly reduce the amount of processing liquid brought into the post bath from the front bath, and is highly effective in preventing performance deterioration of the processing liquid. This is particularly effective in shortening time and reducing the amount of processing solution replenishment.

After the delineation treatment, the silver halide color photographic light-sensitive material of the present invention is generally subjected to a water washing and/or stabilization process.

The amount of water used in the washing process depends on the characteristics of the photosensitive material (for example, depending on the materials used such as couplers), the intended use, the salt in 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 over a wide range. Among these, the relationship between the number of washing tanks and the amount of water in the multistage countercurrent method is
urn-al or the 5ociety of
Motion Picture and Te1e-v
ision Engineers Volume 64, P, 24
8-253 (May 1955 issue).

According to the multi-stage countercurrent method described in the above-mentioned literature, the amount of washing water can be significantly reduced, but the increased residence time of water in the tank causes bacteria to propagate and the generated floating particles to adhere to the photosensitive material. In the processing of the color photosensitive material of the present invention, such problems can be solved by:
The method for reducing calcium ions and magnesium ions described in JP-A No. 62-288.838 can be used very effectively. Also, JP-A-57-8,542

It is also possible to use the fungicides described in (1986).

The pH of the washing water in the processing of the photosensitive material of the present invention is 4 to 4.
9, preferably 5-8. The washing water temperature and washing time can also be set variously depending on the characteristics of the photosensitive material, its use, etc., but generally it is 20 seconds to 10 minutes at 15 to 45°C, preferably 20 minutes.
A range of 30 seconds to 5 minutes at 5 to 40°C is selected. Furthermore, the photosensitive material of the present invention can also be directly processed with a stabilizing solution instead of washing with water.

In such stabilization treatment, Japanese Patent Application Laid-Open No. 57-854
All known methods described in No. 3, No. 58-14834, and No. 60-220345 can be used.

Further, following the water washing treatment, a further stabilization treatment may be performed. An example of this is a stabilization bath containing a dye stabilizer and a surfactant, which is used as a final bath for color photographic materials. Examples of dye stabilizers that can be used include aldehydes such as formalin and glutaraldehyde, -methylol compounds, hexamethylenetetramine, and aldehyde sulfite adducts.

Various chelating agents and antifungal agents can also be added to this stabilizing bath.

The overflow liquid resulting from the water washing and/or replenishment of the stabilizing liquid can also be reused in other processes such as the desilvering process.

When each of the above-mentioned processing liquids is concentrated by evaporation in processing using an automatic processor or the like, it is preferable to correct the concentration by adding water.

The silver halide color light-sensitive material of the present invention may contain a color developing agent for the purpose of simplifying and speeding up processing.

A sample 102 was prepared by using the sample for the twelfth layer.

Each sample was passed through an optical wedge using a 4,800"K tungsten light source, exposed to 20CH3, and subjected to the development treatment shown in Table 1 to evaluate its photographic performance. Sample 101
and 102 had equivalent sensitivity and gradation.

(Preparation of sample A, !=8) Process 12 images of sample 101 using a 110 cartridge in accordance with the ANS+ standard, leave it at 25°C and 55% relative humidity for 2 days, and form a moisture-proof film of 1105InIIX28r under the same conditions ( Sample A was a Fujifilm 110 cartridge packaging film that was sealed and sealed in the same film.

Sample B was obtained by packaging Sample 102 in the same manner.

(Preparation of Samples C and D) Sample 101 was processed by taking 12 images using a 126 cartridge according to the ANS I standard, and processed at 25°C and 55% relative humidity.
Sample C was obtained by allowing the sample to stand for several days and then sealing it in a 106 ma x 50 mm moisture-proof film (same as above) under the same conditions.

Sample 102 was packaged in the same manner as sample 102.

(Creation of Samples E and F) Twelve sheets of sample 101 were processed into cartridges as shown in Figure 2, and left at 25°C and relative humidity of 55% for 20 minutes. (Same as above) was sealed and sealed as a sample.The screen size of this cartridge is 2411 x 36 mm.

The results are shown in Table 4.

Table 4 Evaluation of effective screen area 1) The print area was 94 cd.

Legend for 2) O: Good Δ: Slightly Poor ×: Poor From the above, it can be seen that the print image quality with a negative size of 3 cd or less is inferior.

To provide acceptable print quality, a negative size of at least 3c4, preferably at least 6c+j, is required.

Example 4 Using sample E of Example 1, the same subject was subjected to bridge shape processing at a constant distance. However, the aspect ratio of the negative screen was varied while keeping the area constant. Prints with various aspect ratios were made from these negatives with constant stretching magnification.

The results are shown in Table 5.

Table 5 Evaluation of screen aspect ratio Based on the above, the print aspect ratio should be 1.3~
It can be seen that 1.7 times is preferable. Therefore, it can be seen that it is desirable that negative films also have a corresponding aspect ratio.

Example 5 [Preparation of Emulsion C] In the method for preparing Emulsion A described in Example 1, the number of grains of silver halide prepared in step a was reduced to contain 2 mol% of iodine in total. Average particle diameter is 2.1μm
, the coefficient of variation of the equivalent sphere diameter is 1 with an average aspect ratio of 7.5.
An emulsion containing 7% monodisperse tabular grains was prepared.

[Adjustment of emulsion]

In the preparation method for emulsion B described in Example 1, by reducing the number of silver halide grains in the seed crystal, the equivalent sphere diameter was 1.5 μm.
An emulsion containing dodecahedral grains with a coefficient of variation of equivalent sphere diameter of 15% was prepared.

[Creation of multilayer color photosensitive material]

Emulsion C is used as the 5th layer, 10th layer, and 1st layer of the photosensitive material shown below.
Since it is used in 6 layers, each layer has the composition shown below for color aggravation and chemical sensitization in order to optimize color aggravation and chemical sensitization for each layer. Sample 501, which is a multilayer color photosensitive material, was prepared.
