Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photosensitive material for printing plate making, and more particularly to a photosensitive material having excellent Mincho Gothic reproducibility and good eye-stretching properties.

0002

BACKGROUND OF THE INVENTION The photoengraving process using silver halide photographic light-sensitive materials involves the process of converting a continuous tone original into a halftone image. The method includes a step of converting into a set of dots and a step of converting the halftone dot image obtained in this step into a halftone image with better sharpness, that is, a turning step.

It is essential that the photosensitive materials used in these processes have high contrast in order to obtain good halftone dot quality.

Conventionally, as a method for obtaining such characteristics, a light-sensitive material made of a silver chlorobromide emulsion with relatively fine grains, a narrow particle size distribution, and a high silver chloride content is subjected to alkaline hydroquinone development with a very low sulfite ion concentration. A method of processing with a liquid, the so-called lith development method, is known.

[0005] However, when this method is used, the storage stability is extremely poor due to the low concentration of sulfite ions in the developer, and the development speed is slow due to the use of hydroquinone as a single active ingredient, making rapid processing impossible. .

Therefore, high contrast can be achieved by processing with a so-called PQ type or MQ type developer containing a relatively high concentration of sulfite, which contains a super-additive developing agent that has good storage stability and can be processed rapidly. The development of new photosensitive materials is desired, and Japanese Patent Publications No. 59-17825, No. 59-17818, No. 59-17819, No. 59-17820, No. 59-
No. 17821, No. 59-17826, No. 59-178
Each publication of No. 22 discloses a silver halide photographic material containing a tetrazolium compound.

[0007] The method of processing photosensitive materials containing these tetrazolium compounds with a superadditive developer to obtain a silver image with high contrast is an extremely revolutionary technology compared to the conventional lithographic development technology. can. On the other hand, as a method for quickly obtaining high contrast images based on another principle, for example, US Pat.
No. 224401, JP-A-51-16623, JP-A No. 51-
As seen in No. 20921 and the like, silver halide photographic materials containing a hydrazine compound are disclosed.

However, such high-contrast photosensitive materials have the disadvantage that the reproducibility of characters is poor when line drawings are photographed. In other words, for example, when exposing a manuscript containing a mix of Grade 7 Mincho and Gothic fonts with a photoengraving camera, if the exposure is held back so that the fine lines of the Mincho fonts are not crushed, the density of the ground that should be blackened will decrease. and pinholes increase,
The line width of Gothic fonts can be made thin without increasing to the desired thickness. On the other hand, if you adjust the exposure to match the line width of a Gothic font, the fine lines of a Mincho font will be crushed. For this reason, in the printing and plate making industry, a method is used in which the Mincho and Gothic fonts are photographed separately and then combined in a later process, but this method requires twice the amount of work and materials.

[0009] Also, in the process of enlarging or reducing a document that has been converted into halftone dots, which is called stretching, there is a problem in that the range of halftone dots is clogged when a high-contrast photosensitive material is used. Therefore, when performing eye stretching work, a filter called a leaf filter is usually used to perform the exposure work. However, the quality of the finish fluctuates due to the need to attach and detach the filter each time the exposure is performed and the degree of deterioration of the filter, which has become a problem.

0010

OBJECTS OF THE INVENTION In order to solve the above-mentioned problems, an object of the present invention is to improve the reproducibility of Mincho typefaces and Gothic typefaces without deteriorating the sharpness of line drawings, and to improve the reproducibility of Mincho typefaces and Gothic typefaces without using a filter. An object of the present invention is to provide a silver halide photographic light-sensitive material for printing plate making which can be stretched.

[0011]

[Structure of the Invention] The above object of the present invention is to provide a silver halide photographic material having at least two coating layers on the same side of a support, in which the emulsion layer is spectral sensitized in the 400 to 500 nm region. and a dye having an absorption peak in the range of 350 to 500 nm is added to the non-photosensitive layer on the same side as the photosensitive layer and far from the support, and the dye has the following general formula [I] or [
This is achieved by a silver halide photographic material characterized by containing the compound of [II] or [III] in the photosensitive layer.

[0106] The developing agent is usually 0.01 mol/l to 1.2 mol/l.
Preferably it is used in amounts of mol/l.

[0107] Sulfites are used as preservatives in developing solutions, and examples of such sulfites include sodium sulfite,
These include potassium sulfite, lithium sulfite, ammonium sulfite, sodium bisulfite, potassium metabisulfite, and sodium formaldehyde bisulfite. The amount of sulfite is preferably 0.2 mol/l or more, particularly 0.4 mol/l or more. Further, the upper limit is preferably 2.5 mol/l.

The pH of the developer is preferably in the range of 9 to 13, more preferably in the range of 10 to 12. Alkaline agents used for pH adjustment include sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, trisodium phosphate, and potassium triphosphate.
Contains H regulator. Buffers such as JP-A-61-28708 (borates), JP-A-60-93439 (eg, sucrose, acetoxime, 5-sulfosalcylic acid), phosphates, carbonates, etc. may be used.

Those described in No. 933 may also be used.

[0112] In the present invention, "developing time" and "fixing time" respectively refer to the time from when the photosensitive material to be processed is immersed in the developing tank liquid of an automatic processing machine until it is immersed in the next fixing liquid; This refers to the time from immersion in water to the time it is immersed in the next washing tank liquid (stabilizing liquid). Further, "washing time" refers to the time during which the product is immersed in the washing tank liquid.

[0113] Also, "drying time" is usually 35°C to 100°C.
The automatic processing machine is equipped with a drying zone in which hot air, preferably 40 to 80 degrees Celsius, is blown, and the term refers to the time the product is in the drying zone.

[0114] The development temperature and time are approximately 25°C to 50°C.
0 seconds or less, but preferably 6 seconds to 2 seconds at 30°C to 40°C
It is 0 seconds. The fixer is an aqueous solution containing thiosulfate and has a pH of 3.8 or higher, preferably 4.2 to 5.5.

Examples of the fixing agent include sodium thiosulfate 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 fixing agent used can be varied as appropriate, and is generally about 0.1 to about 6 mol/l.

The fixer may also contain water-soluble aluminum salts that act as hardeners, such as aluminum chloride, ammonium sulfate, potassium alum, and the like. In the fixing solution, tartaric acid, citric acid, or conductors thereof can be used alone or in combination of two or more kinds. Those containing 0.005 mol or more of these compounds per liter of fixer are effective, especially 0.01 mol/l to 0.0 mol/l.
3 mol/l is particularly effective.

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

The fixing solution may optionally contain a preservative (for example, sulfite, bisulfite), a pH buffering agent (for example, acetic acid, nitric acid), a pH adjuster (for example, sulfuric acid), and a chelating agent with water softening ability. and the compounds described in Japanese Patent Application No. 60-213562.

The fixing temperature and time are preferably 6 seconds to 1 minute at about 20°C to about 50°C, more preferably 6 seconds to 30 seconds at 30°C to 40°C, even more preferably 6 seconds at 30°C to 40°C. ~20 seconds.

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, the fixer concentrate may be comprised of an I agent. The most preferable conditions are the same as those for the developer.

[0121] The fixer solution as the I agent can stably exist at a pH of 4.5 or higher, more preferably at a pH of 4.6.
It is 5 or more. This is because if the pH is less than 4.5, the thiosulfate will decompose and eventually become sulfided, especially if the fixer is left for a long period of time before it is actually used. Therefore, in a pH range of 4.5 or higher, less sulfur dioxide gas is generated, which improves the working environment. The upper limit of pH is not so strict, but if it is fixed at too high a pH, the pH of the membrane will deteriorate even after washing with water.
The pH is limited to about 7 because the H content increases, membrane swelling increases, and therefore the drying load increases. A fixing solution that hardens a film using an aluminum salt has a pH limit of 5.5 to prevent precipitation of the aluminum salt.

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).

[0123] 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 1:0 to 0. The total amount of each of these developing solutions and fixing solutions is 50 ml to 1500 ml per 1 m2 of photosensitive material.
It is preferable that

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

[0125] For the washing or stabilization treatment, any method known in the art can be applied, 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 for washing water or stabilizing liquid, not only is it possible to save water by replenishing less than 3 liters per 1 m2 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 developing solution and the fixing solution can be supplied from a common stock tank, making it possible to make the automatic developing machine even more compact.

[0126] When water treated with anti-mildew means is used in combination with washing water or stabilizing liquid, the formation of limescale etc. can be effectively prevented.
0 to 3 liters per m2 of photosensitive material, preferably 0 to 1 liter,
Water-saving treatment can be carried out.

[0127] Here, when the replenishment amount is 0, no replenishment is performed at all except for appropriately replenishing the amount of washing water in the washing tank that has decreased due to natural evaporation, etc., that is, there is virtually no replenishment. This refers to cases where the "reserved water" treatment method is used.

As a method for reducing the amount of replenishment, a multistage countercurrent system (for example, two stages, three stages, etc.) has been known for a long time. If this multi-stage countercurrent method is applied to the present invention, the photosensitive material in the fixer will be processed in a progressively cleaner direction, that is, in sequential contact with the processing solution that is not contaminated with the fixer, resulting in even more efficient processing. Washing is done. According to this, unstable thiosulfates and the like are appropriately removed, the possibility of discoloration and fading is further reduced, and an even more significant stabilizing effect can be obtained. The amount of water used for washing is also much smaller compared to conventional methods.

[0129] When washing with a small amount of washing water,
It is more preferable to provide a squeeze roller cleaning tank as described in No. 0-172968.

[0130] Furthermore, 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. 60-235133. As described, it can also be used in a processing solution having 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.

[0135] The water treated with anti-mildew means and stored in the water stock tank is diluted with water for diluting the stock solution of the processing solution such as the developer/fixer, and the amount thereof added is preferably 0.01 to 10 g/l, more preferably 0. .1 to 5 g/l.

Furthermore, in addition to the silver image stabilizer, various surfactants can be added to the washing water for the purpose of preventing uneven water droplets. 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, adjusting membrane pH (
various buffering agents (e.g. borates, metaborates, borax, phosphates, carbonates, potassium hydroxide, sodium hydroxide, aqueous ammonia, monocarboxylic acids, dicarboxylic acids, Typical examples include aldehydes such as formalin (used in combination with carboxylic acids, etc.) and formalin. In addition, chelating agents, fungicides (thiazole type, isothiazole type, halogenated phenol,
Various additives such as sulfanilamide, benzotriazole, etc.), surfactants, optical brighteners, and hardening agents may be used, and two or more compounds for the same or different purposes may be used in combination.

[0138] Furthermore, it is preferable to add various ammonium salts such as ammonium chloride, ammonium nitrate, ammonium sulfate, ammonium phosphate, ammonium sulfite, and ammonium thiosulfate as a membrane pH adjusting agent for the processing solution in order to improve image storage stability.

[0139] The water washing or stabilization bath temperature and time in the above method are preferably 0°C to 50°C and 6 seconds to 1 minute, but 15°C.
6 to 30 seconds at ~40°C, more preferably 15
C. to 40.degree. C. for 6 seconds to 15 seconds is preferred.

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 about 40℃~about 1
The drying time is suitably changed depending on the surrounding conditions, but is usually about 5 seconds to 1 minute, more preferably about 5 seconds to 30 seconds at 40 to 80 degrees Celsius.

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 from development, fixing, washing with water, and drying is within 100 seconds, preferably within 60 seconds. Here, "dry to dry" refers to the time from the moment the leading edge of the photosensitive material to be processed enters the film insertion area of the processor to the moment the leading edge emerges from the processor after being processed. .

[0146] As shown in Table 1, the addition flow rate was gradually increased over the total addition time of 80 minutes.
The addition was carried out while keeping the g value constant.

The EAg value was changed from 160 mV to 120 mV using a 3 ml/l aqueous sodium chloride solution 5 minutes after the start of addition, and this value was maintained thereafter until the completion of mixing.

[0148] In order to keep the EAg value constant, the EAg value was controlled using a 3 mol/l aqueous sodium chloride solution.

For the measurement of the EAg value, a metal silver electrode and a double junction type saturated Ag/AgCl reference electrode were used (the electrode configuration was a double junction disclosed in JP-A-57-197534). ).

A variable flow rate roller tube metering pump was used to add solutions B and C. Furthermore, during the addition, the emulsion was sampled and observed using an electron microscope to confirm that no new particles were generated within the system.

During the addition, the pH value of the system was controlled to be kept constant at 3.0 using a 3% aqueous nitric acid solution. After adding Solutions B and C, the emulsion was subjected to Ostwald ripening for 10 minutes, and then desalted and washed with water using a conventional method. Then, 600 ml of an aqueous solution of ossein gelatin (containing 30 g of ossein gelatin) was added, and the emulsion was heated at 55°C. After dispersion by stirring for 30 minutes, 750
