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 light-sensitive materials include so-called instamatic 126-size cartridges with a screen size of 2.8 cm + 2.85 cm (standard content is ANSI/ASCPH1,4O-1984).
) and 1.3cm x 1.1cvn so-called pocket-sized 110 size cartridge (ANS1./ASC
PH1, 55-1986), etc. have been used. It is true that these cartridges have advantages such as being easy to load into the camera, being less likely to malfunction, not requiring winding when taking out the film after shooting, and being easy to take out and reload the film in the middle of the bridge. 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.

In addition, recently, disposable photosensitive material cartridges such as "Utsurun desu" and "Utsurun desu Hi" have become a problem, but because they are disposable, the price per frame is high. was there.

On the other hand, the monodisperse silver halide emulsion of the present invention is known to be used in ordinary silver halide photosensitive 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, graininess is noticeable, they tend to blur during printing, making it difficult to obtain good sharpness, and the unfavorable 1-side ratio of the screen causes visual psychological and physiological concerns. .

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.

(Intelligence B 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 graininess, 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 purpose is to supply the photosensitive material which is simple and convenient.Fifthly, the camera is not disposable and the price per frame is low.

(Means for Solving the Problems) An object of the present invention is to provide a silver halide photographic light-sensitive material housed in a cartridge in which the light-sensitive material is composed of a small amount of silver halide grains (both consisting of one type of substantially monodispersed silver halide grains). The cartridge comprises a roll chamber for storing a roll of unexposed light-sensitive material, a winding chamber for winding up the exposed light-sensitive material, and a bridge section connecting them and having an opening; The effective screen area per frame exposed to the photosensitive material at the aperture is 3.01 or more and 25.0aJ or less, and the ratio of the length of the long side to the length of the short side of the screen of one frame is 1.01. This can be achieved by using a silver halide photographic light-sensitive material housed in a cartridge characterized in that the ratio is 2 or more and 2,0 or less.

The cartridge of the present invention comprises a film roll chamber for storing a roll of unexposed light-sensitive material, a winding chamber for winding up exposed light-sensitive material, and a pre-fuji portion connecting these, and having an opening. The effective screen area per frame exposed to the photosensitive material is 3.0cm2 or more and 25.0C11 or less, and the ratio of the length of the long side to the length of the short side of the screen for one frame (aspect ratio) is 1. It is 2 or more and 2.0 or less.

The preferred effective screen area is 6.0cm2 or more and 16°Oa.
J or less, particularly preferably 8. 〇- or more 10.0c
m2 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 photographic photography anytime and anywhere.

A preferred aspect ratio is 1.3 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 with general users.

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

In preferred films, 35±1%, particularly preferably 35

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.

Specific examples of the light shielding means are illustrated below.

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 useful as color developing agents, but p-phenylenediamine compounds are preferably used, representative examples of which are 3-methyl-4-amino-N, N-diethylaniline, 3-methyl -4-amino-N-ethyl-N-
β-hydroxyethylaniline, 3-methyl-4-amino-N-ethyl-N-β-methanesulfonamidoethylaniline, 3-methyl-4-amino-N-ethyl-β-
Examples include methoxyethylaniline and their sulfates, hydrochlorides, p-toluenesulfonates, and the like. 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 contains p) 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. In addition, if necessary, hydroxylamine, diethylhydroxylamine, sulfites, hydrazines such as N,N-biscarphoki-2-dimethylhydrazine, phenylsemicarbazides,
Various preservatives such as triethanolamine, catechol sulfonic acids, organic solvents such as ethylene glycol, 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 agents, various chelating agents such as aminopolycarboxylic acids, aminopolyphosphonic acids, alkylphosphonic acids, and phosphonocarboxylic acids, such as ethylenediamine. Tetraacetic acid, nitrilotriacetic acid, diethylenetriaminepentaacetic acid,

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 generally 9 to 12. Although the amount of replenishment of these developing solutions depends on the color photographic light-sensitive material being processed, it is generally less than 3β per square meter of light-sensitive material, and by reducing the bromide ion concentration in the replenisher,
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, Capacity of treatment liquid (c+*3) The above aperture ratio is preferably 0.1 or less, more preferably 0.001 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 steps such as bleaching, bleach-fixing, fixing, washing, and stabilization.Also, the amount of replenishment can be reduced 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 high temperature binding 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. As bleaching agents, for example, compounds of polyvalent metals such as iron (I[[), peracids, quinones, nitro compounds, etc. are used. Typical bleaching agents include organic complex salts of iron (Ill), such as ethylenediamine tetra Aminopolycarbonate WIM such as acetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, 1,3-diaminopropanetetraacetic acid, glycol etherdiaminetetraacetic acid, or complex salts such as citric acid, tartaric acid, malic acid, etc. may be used. I can do it. Among these, aminopolycarboxylic acid iron (III) complex salts, including ethylenediaminetetraacetic acid iron (I[[) complex salt and 1,3-diaminopropanetetraacetic acid iron (I[[H!) salt] require rapid processing and environmental pollution. Preferable from the viewpoint of prevention, iron aminopolycarboxylate (
The l[[) complex salts are particularly useful in both bleach and bleach-fix solutions. These iron aminopolycarboxylic acids (

Bromide ion etc. can be used. Among these, compounds having a mercapto group or a disulfide group are preferred from the viewpoint of a large promoting effect, and are particularly preferred, as described in U.S. Pat.
．． The compounds described in U.S. Pat. No. 630 are preferred, and the compounds described in U.S. Pat. No. 4,552,834 are also preferred. These bleach accelerators are particularly effective when bleach-fixing.

In addition to the above-mentioned compounds, the bleaching solution and bleach-fixing solution preferably contain an organic acid for the purpose of preventing bleach staining. Particularly preferred organic acids have an acid dissociation constant (pKa) of 2.
-5, specifically acetic acid, propionic acid, etc. are preferred.

Examples of fixing agents used in fixing solutions and bleach-fixing solutions include thiosulfates, thiocyanates, thioether compounds, thioureas, and large amounts of iodide salts, but thiosulfates are generally used. ammonium thiosulfate is the most widely used. In addition, it is also preferable to use thiosulfate, thiocyanate, thioether compounds, thiourea, etc. as preservatives for fixing solutions and bleach-fixing solutions.
Sulfites, bisulfites, carbonyl bisulfite adducts, or the sulfinic acid compounds described in European Patent No. 294769A are preferred.Furthermore, various aminopolycarboxylic acids may be used in the fixer and bleach-fixer 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! It is preferable that stirring be as strong 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 bleaching agent 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
O-(No. 91257, No. 60-191258, No. 60
It is preferable to have a photosensitive material conveying means as described in Japanese Patent Laid-open No. 191259-1912. This effect is particularly effective in shortening the processing time in each step and reducing the amount of processing solution replenishment.

The silver halide color photographic light-sensitive material of the present invention is generally subjected to water washing and/or stabilization steps after desilvering treatment.

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 application, 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 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 of 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 water used for washing can be significantly reduced, but due to the increase in the residence time of water in the tank, bacteria will breed, and the generated suspended matter will 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

“Encyclopedia of Antibacterial and Antifungal Agents” edited by the Society of Industrial Engineers and the Japan Society of Antibacterial and Antifungal Agents (
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 30 seconds to 5 minutes at 25 to 40°C. A range 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. 0 Dye stabilizers that can be used include aldehydes such as formalin and glutaraldehyde 1
9, N-methylol compounds, hexamethylenetetramine, aldehyde sulfite adducts, and the like.

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

The overflow liquid from water washing and/or replenishment of the stabilizing liquid can 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 incorporate a color developing agent for the purpose of simplifying and speeding up the processing.In order to incorporate a color developing agent, it is preferable to use various precursors of the color developing agent6.
