Description

Detailed Description of the Invention [0001] The present invention relates to a method for developing a silver halide photographic light-sensitive material, which is suitable for rapid processing and has good dimensional stability. The present invention relates to a method for developing a photosensitive material in an automatic processing apparatus. [0002] In recent years, scanner systems have been widely used in the field of printing plate making. There are various types of recording devices that use scanner-based image forming methods. There are lasers, semiconductor lasers, etc. The photosensitive materials used in these scanners are required to have various properties, especially 10-3.
Even under such conditions, high sensitivity and high contrast are essential conditions since the exposure is for a short time of ~10-7 seconds. However, in the printing industry, there is a strong desire to improve the efficiency and speed of work, and there is a wide range of needs for faster scanning and shorter processing time for photosensitive materials. In order to meet these needs in the printing field, exposure machines (scanners, plotters) are required to speed up scanning, increase the number of lines and narrow the beam for higher image quality, and silver halide photographic sensitizers Materials are desired to have high sensitivity, excellent stability, and rapid development processing. What we mean by rapid development processing is that after inserting the leading edge of the film into an automatic processor,
This refers to a process in which the time it takes for the leading edge of the film to emerge from the drying section after passing through the transition section, washing tank, and drying section is 15 to 60 seconds. [0003] Silver halide photographic materials generally have a layer on at least one side of a support containing a hydrophilic colloid such as gelatin as a binder. Such a hydrophilic colloid layer has the disadvantage that it easily expands and contracts due to changes in humidity and temperature. Dimensional changes in photographic materials due to expansion and contraction of the hydrophilic colloid layer are a very serious drawback, particularly in photographic materials for printing. Several methods have been proposed for improving the dimensional stability of photographic materials for printing. For example, techniques for regulating the thickness ratio between the hydrophilic colloid layer and the base (US Pat. No. 3,201,250, etc.), techniques for incorporating polymer latex into the hydrophilic colloid layer (Japanese Patent Publications No. 39-4272, No. 39-17702, No. 43) -13482, US Patent No. 45-5331, US Patent No. 2376005, US Patent No. 2763625, US Patent No. 277
No. 2166, No. 2852386, No. 2853457, No. 3397988, No. 3411911, No. 341
1912, etc.), and a technique of providing a waterproof coating layer as an undercoat on the surface of a support (Japanese Patent Application Laid-open No. 60-3627, etc.). However, even if the photosensitive material itself is improved in this way, it is essentially difficult to improve dimensional stability under all temperature and humidity environments as long as it has a layer containing a hydrophilic colloid such as gelatin as a binder. . Furthermore, as far as we know, there has been no technology for improving the dimensional stability of photosensitive materials in automatic processing equipment. Conventionally, various methods have been proposed for controlling the drying conditions of the drying section of an automatic developing processing apparatus by controlling the drying conditions using a heater or the like. (Unexamined Japanese Patent Publication No. 56-0952
No. 39, JP-A-63-049760, JP-A-63-2
No. 36043, etc.) In these conventional control methods, the aim was to find a better drying method mainly from the viewpoints of speeding up drying, energy economy, emulsion film quality, transportability of light-sensitive materials, etc. For example, methods for speeding up drying by applying weaker drying air in the first half and stronger in the second half, preheating heaters at lower temperatures when photosensitive materials are not available to improve energy economy, and installing automatic processing equipment. The temperature and humidity in the room (hereinafter referred to as "ambient temperature and humidity") are detected, and based on that information, it is possible to prevent excessive drying of photosensitive materials and deterioration of film quality, and to prevent drying of photosensitive materials. There are methods to prevent transport defects from occurring due to a shortage of material. However, with these conventional methods, it has been impossible to improve the dimensional stability of photosensitive materials under all temperature and humidity conditions. For example, during periods of low humidity such as winter, the drying air temperature of the processing equipment is set high, resulting in excessive drying of the photosensitive material, a so-called over-drying state, which causes the size of the photosensitive material to increase. A phenomenon occurs. In addition, during periods of high humidity such as the rainy season,
If the drying air temperature is set to such a level that the photosensitive material is barely dry, a phenomenon occurs in which the size of the photosensitive material shrinks. In the industry, this phenomenon is expressed as poor dimensional stability due to processing. This is a serious drawback especially in photosensitive materials for printing. On the other hand, in many fields from the perspective of environmental conservation,
Resources, generated gas, waste water, waste, etc. are being reviewed. In the field of photo processing, we aim to save resources, reduce the amount of waste water,
In order to reduce the amount of containers used, there is an increasing need to reduce the amount of replenishment of processing liquid used for processing photosensitive materials. However, reducing the developer replenishment amount significantly slows down the development speed, and reducing the fixer replenishment amount significantly slows the fixer speed.
250 to 500 ml of developer and 500 to 500 ml of fixer per 2
800ml) is being refilled. In order to increase the development speed and fixing speed, the processing temperature is increased or the stirring conditions during processing are strengthened, but these methods cause various problems such as generation of odor and increase in equipment cost. As described above, there has been a strong desire for improvements in silver halide photographic materials and automatic processing equipment that are suitable for rapid processing, have excellent dimensional stability, and can reduce the amount of replenishment of processing solutions. SUMMARY OF THE INVENTION An object of the present invention is to provide a silver halide photographic light-sensitive material that has rapid processing suitability, excellent dimensional stability, and can reduce the amount of replenishment of a processing solution, and to provide an automated silver halide photographic material. An object of the present invention is to provide a development processing apparatus. SUMMARY OF THE INVENTION These objects of the invention provide a silver halide emulsion layer having at least one silver halide emulsion layer on a support and at least one protective layer on top of the emulsion layer. In a method of developing a silver photographic light-sensitive material using an automatic processing device after exposure, the coating amount of gelatin in the protective layer is 0.5 g/m2 or less, and the total coating amount of gelatin including the emulsion layer is 2.5 g/m2 or less, and in the drying section of an automatic development processing apparatus that develops the silver halide photographic light-sensitive material, the holding of the light-sensitive material immediately after squeezing the light-sensitive material after washing with water. After drying 65% of the water content, set the drying air temperature in the drying processing section to the conditions shown in the shaded area in Figure 1 based on the atmospheric temperature and humidity conditions at the location where the automatic processing equipment is installed. This was achieved by a method for developing a silver halide photographic material, which is characterized by drying the silver halide photographic material. The silver halide used in the present invention may be any one of silver chloride, silver bromide, silver iodide, silver chlorobromide, silver chloroiodide, silver iodobromide, silver chloroiodobromide, etc. . In the present invention, among the above-mentioned silver halides, silver chloroiodobromide, silver chlorobromide, and silver iodobromide are preferred. More preferably silver iodide is 0 to 1
Silver chlorobromide or silver chloroiodobromide containing mol % is advantageously used. The average grain size of the silver halide used in the present invention is preferably fine grains (for example, 0.7μ or less), particularly 0.7μ or less.
．． It is preferably 5μ or less. There are basically no restrictions on the particle size distribution, but monodisperse distribution is preferable. Monodisperse herein means that at least 95% of the particles by weight or number of particles is composed of particles having a size within ±40% of the average particle size. Silver halide grains in photographic emulsions are regular (cubic, octahedral, etc.) grains.
r) It may have a crystalline form, or it may have an irregular crystal shape such as a spherical shape or a plate shape, or a composite shape of these crystal shapes. The interior and surface layers of the silver halide grains may consist of a uniform phase or may consist of a simple phase. Two or more silver halide emulsions formed separately may be used in combination. Further, the silver halide emulsion layer may be a single layer or a multilayer (two layers, three layers, etc.), and in the case of a multilayer, different silver halide emulsions may be used. Good and
The same one may be used. In the silver halide emulsion used in the present invention, cadmium salt, sulfite, lead salt, thallium salt, rhodium salt or its complex salt, iridium salt or its complex salt, etc. are allowed to coexist in the silver halide grain formation or physical ripening process. Good too. In the present invention,
It is preferable to use a water-soluble rhodium salt, typically rhodium chloride, rhodium trichloride, rhodium ammonium chloride, or the like. Furthermore, complex salts of these can also be used. The time for adding the rhodium salt is limited to before the end of the first ripening during emulsion production, and it is particularly desirable to add it during grain formation, and the amount added is 1 mole of silver.
The range is preferably from ×10 −8 mol to 1×10 −6 mol. Silver halides particularly suitable for use in the present invention are prepared in the presence of 10@-8 to 10@-5 moles of iridium salt or complex salt thereof per mole of silver. In the above, it is desirable to add the iridium salt in the above amount before the completion of physical ripening in the silver halide emulsion manufacturing process, especially during grain formation. The iridium salt used here is a water-soluble iridium salt or an iridium complex salt, such as iridium trichloride, iridium tetrachloride, potassium hexachloroiridate (III), hexachloroiridium (I
V) acid potassium, ammonium hexachloroiridate(III) acid, etc. Gelatin is advantageously used as a binder or protective colloid in photographic emulsions, but other hydrophilic colloids can also be used.

Can be done. The silver halide emulsion used in the present invention does not need to be chemically sensitized, but may be chemically sensitized. Sulfur sensitization, reduction sensitization, and noble metal sensitization methods are known as methods for chemical sensitization of silver halide emulsions, and any of these methods can be used alone or in combination for chemical sensitization. Good too. Among the noble metal sensitization methods, the gold sensitization method is a typical method and uses a gold compound, mainly a gold complex salt. There is no problem in containing complex salts of noble metals other than gold, such as platinum, palladium, and rhodium. As the sulfur sensitizer, in addition to the sulfur compounds contained in gelatin, various sulfur compounds such as thiosulfates, thioureas, thiazoles, rhodanines, etc. can be used. As the reduction sensitizer, stannous salts, amines, formamidine sulfinic acid, silane compounds, etc. can be used.

1,3,3a,7) tetrazaindenes), pentaazaindenes, etc.; many compounds known as antifoggants or stabilizers such as benzenethiosulfonic acid, benzenesulfinic acid, benzenesulfonic acid amide, etc. can be added. Among these, preferred are benzotriazoles (e.g. 5-methyl benzotriazole) and nitroindazoles (e.g.
-nitroindazole). Further, these compounds may be included in the treatment liquid. The light-sensitive silver halide emulsion of the present invention may be spectrally sensitized to relatively long wavelength blue light, green light, red light or infrared light using a sensitizing dye. As the sensitizing dye, cyanine dyes, merocyanine dyes, complex cyanine dyes, complex merocyanine dyes, holoholic cyanine dyes, styryl dyes, hemicyanine dyes, oxonol dyes, hemioxonol dyes, etc. can be used.

As the gelatin, in addition to lime-treated gelatin, acid-treated gelatin may be used, and gelatin hydrolysates and gelatin enzymatically decomposed products can also be used. In the present invention, the amount of gelatin applied as a binder is preferably as small as possible in order to obtain suitability for rapid processing and improvement in dimensional stability. In particular, the amount of gelatin coated in the protective layer greatly affects the development speed and fixing speed, and the total coated amount of gelatin including the silver halide emulsion layer affects the drying speed and dimensional stability.

In the present invention, the protective layer preferably consists of two or more layers. Silver halide photosensitive materials have the disadvantage that when stored under low humidity conditions, the hydrophilic colloid layer becomes brittle. In order to improve this, it is preferable to include a polymer latex having a glass transition point (hereinafter referred to as Tg) of 20° C. or lower in the emulsion layer and/or the protective layer. In particular, when the protective layer has two or more layers, it is recommended to include it in the intermediate layer between the emulsion layer and the outermost layer to prevent brittleness without impairing the film strength in the processing solution and adhesion between the sensitive materials under high humidity conditions. It is preferable in that it improves. Further, it is preferable to include colloidal silica in the outermost layer together with other slipping agents, since this improves the slipperiness and at the same time improves the strength of the dried film and further improves the scratch resistance. The amount of colloidal silica added to this outermost layer is 0.00% by weight relative to the amount of binder in the outermost layer.

Washing with water is carried out to almost completely remove the silver salt dissolved during fixing, and is preferably carried out at about 20° C. to about 50° C. for 10 seconds to 3 minutes. Roller conveyance type automatic processors are described in US Pat. No. 3,025,779, US Pat. A roller conveyance type processor consists of four steps: development, fixing, washing, and drying, and although the method of the present invention does not exclude other steps (for example, a stopping step), it is most preferable to follow these four steps. . The replenishment amount of washing water may be 1200 ml/m2 or less (including 0). The case where the replenishment amount of washing water (or stabilizing liquid) is 0 means a washing method using a so-called accumulated water washing method.

Multi-stage countercurrent systems (for example, two-stage, three-stage, etc.) have been known for a long time. [0072] To solve the problem that occurs when the amount of replenishment of washing water is small, good processing performance can be obtained by combining the following techniques.

It is more preferable to provide a squeeze roller and a crossover rack cleaning tank as described in No. 87,252. Further, part or all of the overflow liquid from the washing or stabilizing bath of the present invention, which is generated by replenishing the washing or stabilizing bath with water treated with anti-mold means according to the treatment, is disclosed in Japanese Patent Application Laid-Open No. 60-1999.
As described in No. 235,133 and JP-A No. 63-129,343, it can also be used in a processing liquid having a fixing ability, which is a processing step before that. Furthermore, water-soluble surfactants and antifoaming agents are added to prevent uneven blisters that tend to occur when washing with a small amount of water and/or to prevent the processing agent components that adhere to the squeeze roller from being transferred to the processed film. May be added. Further, a dye adsorbent described in JP-A-63-163-456 may be installed in the washing tank to prevent staining due to dyes eluted from the sensitive material. The light-sensitive material of the present invention exhibits excellent performance in rapid processing using an automatic processor in which the total processing time is 15 to 60 seconds. In the rapid development process of the present invention, the temperature and time of development and fixing are approximately 25°C.
~50°C for up to 25 seconds each, preferably at 30°C
4 seconds to 15 seconds at ~40°C. The total processing time in the present invention is defined as the time after the leading edge of the film is inserted into the insertion slot of the automatic processor, the film passes through the developing tank, transfer section, fixing tank, transfer section, washing tank, transfer section, and drying section. This is the total time it takes for the tip to emerge from the drying outlet. The method of drying a silver halide photographic light-sensitive material in the present invention after developing it with an automatic processing device means that in the drying section, the light-sensitive material immediately after being squeezed after washing with water is dried. 65 of the water you have
After drying the photosensitive material, the temperature of the drying air in the drying processing section is set to the conditions shown by the shaded area in FIG. 1 based on the atmospheric temperature and humidity conditions at the location where the automatic processing device is installed. . In particular, under conditions where the atmospheric humidity is relatively high, the photosensitive material may not dry. In that case, the drying section of the automatic development processing apparatus must be made longer. This is disadvantageous in terms of space saving. Therefore, the drying processing section of the automatic processing device is divided into two zones, front and rear, and the temperature of each drying processing zone is set based on the atmospheric temperature and humidity conditions when installed independently. In the front part, 30 to 65% of the water content of the photosensitive material immediately after squeezing the photosensitive material after washing with water, preferably 40 to 65%.
By drying 65% and setting the drying air temperature at the rear of the drying section to the conditions shown in the shaded area in FIG.
This problem can be solved. In the present invention, development processing refers to development, fixing, and washing with water. Squeezing refers to removing moisture from the surface of a photosensitive material using a roller such as a rubber roller or a resin roller, or an air squeeze method in which air is blown onto the surface of the photosensitive material after washing with water. Next, FIG. 1 will be explained. FIG. 1 shows a region in which drying temperature conditions with excellent dimensional stability can be achieved if the temperature is set to the shaded region surrounded by boundary lines a and b. Here, the boundary line a is the atmospheric humidity R (%RH)
If the drying air temperature is D (°C), then D=2/3*R
It is expressed as +(ambient temperature)+5. Boundary line b is 0≦R≦
At 60, D=2/3*R+(ambient temperature)-35
straight line, when 60≦R≦100, D=-2/3*R
It is represented by a straight line of +(ambient temperature)+45. However, D needs to be higher than the dew point in the range of 60≦R≦100. As a specific method for achieving these, for example, there is a method in which the drying processing section of an automatic processor is divided into two zones, a first half and a second half, and the temperature of the two zones is controlled separately. The drying air temperature in the first half zone is set higher than room temperature so that the photosensitive material dries quickly, and the second half zone is set to the temperature condition shown by the shaded area in FIG. By doing so, the drying of the photosensitive material will not be insufficient and the dimensional stability will also be improved. In the present invention, 65% of the water content of the photosensitive material immediately after squeezing the photosensitive material after washing with water
The following can be dried by radiant heat or high frequency heating. For example, drying methods using far-infrared irradiation, microwave irradiation, and high-frequency heating described in JP-A-1-260445, JP-A-1-260449, and JP-A-1-241004 are preferably used. Further, these means and means using hot air may be combined. Also, Unexamined Japanese Patent Publication No. 1-24
As described in No. 1005, the method may include means for selecting a drying control pattern and controlling the drying section depending on the type of photosensitive material. Next, the present invention will be further explained with reference to Examples, but the present invention is not limited thereto. [Example] Example 1 [1] Preparation of emulsion Liquid I Water

At H, it is 80 liters/s. Dimensional changes due to processing conditions were determined by drilling two 8mm diameter holes at a 200mm interval in a pre-processed sample whose entire surface was exposed to light, and making 1/1000mm holes.
A precision pin gauge was used to accurately measure the spacing between the two holes. The dimension at this time is assumed to be X (unit: mm). Then, after developing with an automatic developing machine, fixing, washing with water, and drying, the dimension after 5 minutes is defined as Y (unit: mm). The dimensional change rate (%) due to treatment was evaluated using the value (Y-X)/200x100. Here, elongation of 20 μm or more or 20 μm with a base length of 200 mm
When a shrinkage of less than m occurs, a dimensional deviation commonly referred to in the industry occurs. Therefore, the dimensional change rate due to treatment -0.
A value of 0.01% or more and 0.01 or less was judged to be good. Dimensional changes were measured under the environmental conditions and drying conditions shown in Table 2.
