Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a silver halide photograph for laser scanners that has good antistatic properties and film transportability without impairing photographic properties, and is spectrally sensitized in the infrared region. It relates to a method of developing and fixing a photosensitive material (hereinafter referred to as a photographic material) to form an image, and in particular, image formation that does not cause processing unevenness even if it is developed in a short time (within 15 seconds). It is about the method.

(Prior art) One of the exposure methods for photographic light-sensitive materials is to scan an original image, and then expose the silver halide photographic light-sensitive material based on the image signal to create a negative or positive image corresponding to the image on the original image. An image forming method using a so-called scanner is known. There are various recording apparatuses that utilize image forming methods using one-scanner type, and a semiconductor laser is used as one of the recording light sources of these one-scanner type recording apparatuses.

Semiconductor lasers are small, inexpensive, easy to modulate, and have a long life. Furthermore, since it emits light in the infrared region, a bright safelight can be used, which has the advantage of improving handling efficiency.

The sensitive material used in this semiconductor laser is a photographic material that is spectrally sensitized in the infrared region, and it is made by adding a certain type of cyanine dye to a silver halide photographic emulsion.
It is obtained by spectral sensitization technology that extends the sensitive wavelength range to longer wavelengths. For spectral sensitization in the infrared region, an enhancing dye that absorbs infrared light is used.

(Problems to be Solved by the Invention) However, the antistatic properties and transportability of the infrared sensitized silver halide photographic light-sensitive materials used for image formation using this semiconductor laser have been insufficient. Met.

Photographic materials generally consist of an electrically insulating support and a photographic layer. During the manufacturing process and during use, photographic materials are subject to contact friction or peeling between the surfaces of the same or different materials, resulting in electrostatic charge. This accumulated electrostatic charge often causes a number of problems, but the most important one is the discharging of the accumulated electrostatic charge before processing, which causes the light-sensitive emulsion layer to become photosensitive. When photographic film is processed, dot-like spots or dendritic or feather-like line speeds are produced. In addition, these accumulated electrostatic charges can cause secondary failures such as dust adhering to the film surface, transport failure in photography or film transport equipment, and uneven coating. It will also happen.

In one-type scanners that use semiconductor lasers, high-speed and accurate film transport is essential, and if transport failures occur due to static electricity, it may not be possible to obtain a correct image (or it may lead to incorrect judgments and serious problems). .

A similar problem occurs during film transport in an automatic processor for rapid processing (particularly before a developing bath).

One way to eliminate the interference caused by static electricity is to increase the electrical conductivity of the surface of the photosensitive material so that the accumulated charges can be dissipated in a short period of time before being discharged.

Therefore, methods have been considered to improve the conductivity of supports and various coated surface layers of photographic materials, and attempts have been made to use various hygroscopic substances, water-soluble inorganic salts, certain surfactants, polymers, etc. It's here.

For example, by incorporating a nonionic surfactant into the surface protective layer, a photographic material having good antistatic properties and transportability can be obtained.

On the other hand, in recent years, it has become desirable to see images quickly even in one-type scanners using semiconductor lasers, and therefore it has become necessary to shorten the developing time (previously 20 seconds or more) than before.

For example, this point has become especially necessary in a system in which a laser scanner process and a development process are performed continuously.

However, it has been found that when photographic materials using the above-mentioned nonionic surfactants are processed with a developing time of less than 15 seconds, image unevenness called "development unevenness" occurs, which has become a serious problem. The uneven development is caused by the above-mentioned nonionic surfactant having very low solubility in the developer and precipitating on the surface of the photosensitive material. It was thought that this was because the particles remained unevenly on the surface of the window material, and development occurred correspondingly unevenly.

This is because the development by the developer remaining unevenly on the surface of the photosensitive material after the development squeeze becomes impossible to ignore because the development speed of the photographic light-sensitive material is increased in order to shorten the development time, and this remains as development unevenness. It's for a reason.

Therefore, the first object of the present invention is to form images by developing and fixing a photosensitive material for laser scanners that is spectrally sensitized in the infrared region and is antistatic so as to reduce power generation with respect to various materials. The goal is to provide a way to do so.

A second object of the present invention is to provide a method for forming an image by developing and fixing a photographic material for a laser scanner that is spectrally sensitized in the infrared region without causing uneven development even when the development time is 15 seconds or less. be.

A third object of the present invention is to provide a method for developing and fixing a photosensitive material for a laser scanner to form an image, which is antistatic and prevents the photosensitive materials from adhering to each other even if the window material is stored for a long period of time. There is a particular thing.

(Means for Solving the Problems) These objects of the present invention provide a silver halide photographic light-sensitive material for laser scanners, which has at least one infrared spectral sensitized silver halide emulsion layer on one side of a support. developing·
In the method of fixing and forming an image, at least one layer on the emulsion layer side of the silver halide photographic light-sensitive material contains at least one nonionic surfactant and a solubility in a developer of 0°005% by weight or more (30% by weight or more). °C) and its surface tension is 45 dynes/c11 or less (in a 1.0 wt% aqueous solution,
This was achieved by an image forming method characterized by containing at least one ionic surfactant having a temperature of 30° C.) and developing within 15 seconds.

The present invention uses a specific ionic surfactant that has surface activity that dissolves in the developer and reduces the interfacial tension to prevent uneven development of photographic light-sensitive materials caused by poor solubility of the nonionic surfactant in the developer. This problem was solved by using a surfactant to ensure uniform development, and as a result, a good image could be obtained even if the development time was less than 15 seconds without impairing antistatic properties and mechanical transportability. This is what I was able to obtain.

The silver halide photographic emulsion spectrally sensitized in the infrared region used in the present invention can be obtained by adding a sensitizing dye having absorption in the infrared region to silver halide grains.

First, a sensitizing dye that absorbs infrared light will be described.

In the present invention, "development time" and "fixing time" respectively mean
The time from when the photosensitive material to be processed is immersed in the developing tank solution of the automatic processing machine until it is immersed in the next fixing solution, and the time from when it is immersed in the fixing tank solution until it is immersed in the next washing tank solution (stabilizing solution). say the time

Further, "washing time" refers to the time during which the product is immersed in the washing tank liquid.

In addition, "drying time" is usually a drying zone in which hot air is blown at 35°C to 100°C, preferably 40°C to 80"C. refers to time.

The developing temperature and time are about 5° C. to about 50° C. for 15 seconds or less, preferably 30° C. to 40° C. for 6 seconds to 15 seconds.

The fixing solution is an aqueous solution containing diosulfate, and has a pH of 3.8.
Above, preferably 4.2 to 5.5. More preferably the pH is 4.65 to 5.5.

Examples of the fixing agent include sodium periosulfate and ammonium thiosulfate, which contain thiosulfate ions and ammonium ions as essential components, and ammonium thiosulfate is particularly preferred from the viewpoint of fixing speed. The amount of adhesion promoter used can be varied accordingly, - from about 0.1 to about 6 mol/Il for ships;
It is.

The fixer may also contain water-soluble aluminum salts that act as hardeners, such as aluminum chloride, ammonium sulfate, potassium alum, and the like.

Tartaric acid, citric acid, or conductors thereof can be used alone or in combination of two or more kinds in the fixer. These compounds are used in fixer l! ! , containing 0.005 mol or more per mol/l is effective, especially 0°O 1 mol/l to 0.03 mol/l
Mol/l is particularly useful.

Specific examples include tartaric acid, potassium tartrate, sodium tartrate, potassium sodium tartrate, citric acid, sodium citrate, potassium citrate, lithium citrate, and ammonium citrate.

The fixer may optionally contain preservatives (e.g. sulfites, bisulfites), pH buffers (e.g. acetic acid, boric acid), pHg
It can contain a conditioning agent (side group: sulfuric acid), a chelating agent with water softening ability, and a compound described in Japanese Patent Application No. 60-218562.

The fixing temperature and time are preferably about 20°C to about 50°C and 6 seconds to 1 minute, more preferably 30°C to 40°C for 6 seconds to 30 seconds, and even more preferably 30°C to 40°C for 6 seconds to 15 seconds. It is.

When the fixer concentrate is replenished into the automatic processor in the method of the invention with water to dilute it as the light-sensitive material is processed, it is most preferred that the fixer concentrate is composed of one part. is the same as for the developer.

The fixer solution can exist stably as a single agent at pH 4,
5 or more, more preferably PH4.65 or more. This is because if the pH is less than 4.5, the thiosulfate will decompose and eventually become sulfurized, especially if the fixer is left for a long period of time before it is actually used. Therefore pH 4,5
Within the above range, sulfur dioxide gas is generated less and the working environment is also improved. The upper limit of pH is not so strict, but if it is too high
If the film is fixed with H, even if it is washed with water thereafter, the membrane pH will become high and the membrane will swell to a large extent, resulting in a large drying load, so the pH is limited to about 7. In fixing solutions that use aluminum salts to harden films, the pH limit for preventing precipitation of aluminum salts is 5.5.

In the present invention, either the developing solution or the fixing solution may be a so-called working solution that does not require dilution water as described above (that is, it is replenished as an undiluted solution).

The amount of each concentrate supplied to the processing tank liquid and the mixing ratio with dilution water can be varied depending on the composition of the concentrate, but generally the ratio of concentrate to dilution water is 1 to 8. The total amount of each of the developer and fixer is preferably 50 ml to 1500 ml per 1 rrl of the photosensitive material.

In the present invention, the photosensitive material is subjected to water washing or stabilization treatment after being developed and fixed.

Any method known in the art can be applied to the washing or stabilization treatment, and water containing various additives known in the art can also be used as the washing water or stabilizing liquid. By using anti-mold water as washing water or stabilizing liquid, not only is it possible to save water by reducing the amount of replenishment to 32 or less per rrr of photosensitive material, but it also eliminates the need for piping for installing an automatic processing machine. It is possible to reduce the number of stock tanks.

That is, the solution dilution water and washing water or stabilizing solution for the developer and fixer can be supplied from a common single layer stock tank, making it possible to further downsize the automatic developing machine.

When water treated with anti-mildew measures is used in combination with washing water or stabilizing liquid, the formation of limescale can be effectively prevented.
0 to 31, preferably 0 to 11, per water saving treatment can be performed.

Here, when the replenishment amount is O, there is no replenishment at all except for appropriately replenishing the amount of washing water in the washing tank that has decreased due to natural evaporation, etc. In other words, the so-called "reservoir water" is essentially not refilled. Refers to cases in which a processing method is used.

As a method for reducing the amount of replenishment, a multi-stage countercurrent system (for example, two stages, three stages, etc.) has been known for a long time.If this multistage countercurrent system is applied to the present invention, the photosensitive material after fixing will gradually increase. Since the processing is carried out in a clean direction, that is, in order to contact the processing solution that is not contaminated with the fixer, more efficient water washing is achieved. According to this, unstable thiosulfate etc. are properly removed. The possibility of discoloration and fading is further reduced, resulting in a more significant stabilizing effect.The amount of washing water is also much smaller than in the past.

When washing with a small amount of water, patent application 1729/1986
It is more preferable to provide a squeeze roller cleaning tank as described in No. 68.

Further, part or all of the overflow liquid from the washing or stabilizing bath, which is generated by replenishing the washing or stabilizing bath with anti-mold water depending on the treatment, is disclosed in Japanese Patent Application Laid-Open No. 60-23
As described in Japanese Patent Application No. 5133, it can also be used in a processing liquid having a fixing ability, which is a processing step before that. This is more preferable because the stock water can be saved and the amount of waste liquid can be reduced.

Anti-mildew methods include the ultraviolet irradiation method described in JP-A No. 60-263939, the method using a magnetic field described in JP-A No. 60-263940, and the use of ion exchange resin described in JP-A No. 61-131632. How to make pure water, patent application 1986-

It is preferable that the water treated with anti-mold measures and stored in a water stock tank be used both as dilution water for the undiluted solution of processing solutions such as the developer-fixer and as washing water, since it takes up less space. The dilution water treated with mold treatment and the washing water (or stabilizing solution) can be stored separately in separate tanks, or only one of them can be taken directly from the tap.

When stored in separate tanks, the washing water (or stabilizing bath) can contain various additives in addition to applying anti-mildew measures as in the present invention.

For example, a chelate compound having a log K value of chelate stability with aluminum of 10 or more may be included. These are effective in preventing scuttling in washing water when the fixing solution contains an aluminum compound as a hardening agent.

Specific examples of chelating agents include ethylenediaminetetraacetic acid (log 16.1; the same applies hereinafter), cyclohexanediaminetetraacetic acid (17.6L, diaminopropanoltetraacetic acid (13,8), diethylenetriaminepentaacetic acid (18

Furthermore, in addition to the silver image stabilizer, various surfactants can be added to the washing water for the purpose of preventing water droplet unevenness. As the surfactant, any of cationic, anionic, nonionic, and amphoteric types may be used. Specific examples of surfactants include compounds described in "Surfactant Handbook" published by Kogaku Tosho Co., Ltd.

Various compounds are added to the stabilizing bath for the purpose of stabilizing the image. For example, adjust the pH (for example, pH 3).
~8) various buffering agents (e.g. borate, metaborate, borax, phosphate, carbonate, potassium hydroxide, sodium hydroxide, aqueous ammonia, monocarboxylic acid, dicarboxylic acid, polycarboxylic acid) Typical examples include aldehydes such as (used in combination) and formalin. In addition, various additives such as chelating agents, bactericidal agents (thiazole type, isothiazole type, halogenated phenol, sulfanilamide, benzotriazole, etc.), surfactants, optical brighteners, hardening agents, etc. may be used. , two or more of the same or different desired compounds may be used in combination.

Further, it is preferable to add various ammonium salts such as lateralized ammonium, ammonium nitrate, ammonium sulfate, ammonium phosphate, ammonium sulfite, and ammonium thiosulfate as a membrane pHjIl adjuster for the processing machine in order to improve image storage stability.

The water washing or stabilization bath temperature and time using the above method is O''
6 seconds to 1 minute at C to 50 °C is preferred, but 15 to 40 °C
more preferably 6 to 30 seconds, and more preferably 15"C to 4
Preferably, the temperature is 6 to 15 seconds at 0°C.

According to the method of the present invention, the developed, fixed and washed photographic material is dried by squeezing out the washing water, that is, by using a squeeze roller method. Drying is carried out at about 40°C to about 100°C, and the drying time can be changed as appropriate depending on the surrounding conditions, but usually it is about 5 seconds to 1 minute, but more preferably about 40°C.
It is about 5 seconds to 30 seconds at a temperature of .degree. C. to 80.degree.

In the present invention, an even more excellent effect is exhibited in that the lower the swelling percentage of the photosensitive material, the shorter the drying time thereof.

According to the method of the present invention, the so-called dry-to-dry processing time for development, fixing, washing, and drying is within 3 minutes and 15 seconds, preferably within 100 seconds, and most preferably within 60 seconds. Is Rukoto. In addition to such a reduction in processing time, the replenisher, which is a one-part component of the developer and fixer, simultaneously simplifies the liquid preparation work and simplifies maintenance.

Here, "dry to dry" means that from the moment the tip of the window material to be processed enters the film insertion part of the processor,
This refers to the time from when the tip is processed to the moment when the tip comes out of the processor.

(Example) The present invention will be illustrated below with reference to Examples, but the present invention is not limited thereto.
