BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for processing a silver halide photographic light-sensitive material, and in particular, using a small-sized processor, there is no increase in the minimum density due to scratches due to collision of the light-sensitive material, The present invention relates to a processing method and a processing apparatus for a silver halide photosensitive material which is free from defects (jamming) and does not deteriorate the output of magnetically recorded information.

2. Description of the Related Art Conventionally, in a silver halide photographic light-sensitive material (hereinafter abbreviated as a light-sensitive material), it is almost impossible to input or output various kinds of information at the time of photographing or printing, and it is slightly optical. It was only possible to input / output the shooting date and time. By the way, JP-A-4-68336 and JP-A-4-68336.
No. 73737, or as disclosed in Japanese Patent Laid-Open No. 5-88283, by providing a transparent magnetic recording layer on the entire surface of a light-sensitive material, shooting conditions such as date and time of shooting, weather, reduction / enlargement ratio, Number of reprints, areas you want to zoom,
It is possible to input the message, development, print conditions, etc. to the sensitive material. Also, various information can be provided even when inputting to a video device such as a TV / video.
This is a promising method for the future.

On the other hand, in the processing method of a silver halide photographic light-sensitive material, color development, desilvering, washing with water and stabilizing treatment are generally carried out. With the recent spread of in-store processing such as minilabs, further miniaturization of processing machines is desired in the market. To reduce the size, it is most effective to make the processing tank have a small volume. Further, since the efficiency of exchanging the processing liquid is increased if the tank volume is small, deterioration of the processing liquid can be suppressed even in a minilab that has a small amount of processing per day, and improvement in quality (photographic performance) can be expected. As such an example, U.S. Patent Nos. 5,311,325, 5,4206,59, 5,436,118,
Color development in the low volume thin layer processing tanks described in JP-A-5386261, JP-A-63-148944, JP-A-2-69331, JP-A-1-129253, JP-A3-119846, JP-A-2-03043, and JP-A-2-230146. A method etc. can be mentioned. For example, in the processing method of US Pat. No. 5,436,118, a thin layer processing tank whose processing path is within 100 times the thickness of the photosensitive material is used. When the thin layer processing tank is continuously processed, the photosensitive material is processed. It has been found that it is easy to come into contact with the tank and the minimum cyan density due to scratches increases, and the photosensitive material is likely to fail (jamming). It was also found that when the photosensitive material having the magnetic recording layer according to the present invention was processed, its magnetic recording performance deteriorated and satisfactory information could not be obtained.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to prevent defective passage in a processing apparatus using a low-volume processing tank, because there is no increase in the minimum density due to scratches due to collision of photosensitive material in the processing tank.

Processing method. (6) A silver halide photographic light-sensitive material having at least one undercoat layer and at least one light-sensitive silver halide emulsion layer on a support is developed, then desilvered, and then washed and / or stabilized. In the processing apparatus, at least one processing tank has a processing tank of V / L ≦ 25, where VmL is the tank volume of the processing section and Lcm is the path length of the photosensitive material from the inlet to the outlet of the processing section. Then, using a developing processor having a conveying speed of 0.1 m to 5 m per minute,
A processing device for a silver halide color photographic light-sensitive material, characterized in that the light-sensitive material whose support is composed of a poly (alkylene aromatic dicarboxylate) polymer is processed.

Hereinafter, the present invention will be described in more detail. The processor will be described first. The tank volume of the processing section referred to herein as VmL means the volume of the portion through which the photosensitive material passes, and excludes the liquid volume of the circulation system and the sub-tank volume for temperature control. The preferred range of V is 50 ≦ V ≦ 50
00, and more preferably 100 ≦ V ≦ 3000. The path length Lcm of the photosensitive material from the inlet to the outlet of the processing section represents the path length from the contact of the photosensitive material with the processing liquid in the processing tank to the discharge from the processing liquid, Lcm
The preferable range of is 2 ≦ L ≦ 200, and more preferably 4 ≦ L ≦ 120. V / L is ≦ 25, but 1
≦ V / L ≦ 20 is a preferable range. The preferred conveying speed is 0.1 m to 5 m / min, more preferably 0.2 m to 3 m / min, most preferably 0.3 m to 1.5 m / min.
m. A preferable tank width W orthogonal to the traveling direction of the photosensitive material is 0.1 cm ≦ W ≦ 10 cm, more preferably 0.3 cm ≦ W ≦ 5 cm, and most preferably 0.
5 cm ≦ W ≦ 3 cm.

The transfer mechanism attached to the processor has (1)
A so-called drum process is known in which a photosensitive material is inserted, conveyed, and sent out in a liquid filled in a narrow gap by the rotation of a drum. 45
It is written in. In this method, the photosensitive material is developed by utilizing the inner wall or the outer wall of the drum, but the outer wall type is preferable from the viewpoint of easy production of the small liquid amount processing tank device.

Further, (2) there is known a roller-conveying type processing machine which conveys a sensitive material by a counter roller, a zigzag roller, etc. by the nip force of the rollers, and these are known as photographic industry February issue (1975) p. ． 71. This method can be preferably used in the present invention because of the ease of making a small device. Further, as described in JP-A-4-95953, it is still more preferable to use a method of providing a groove through which a photosensitive material passes and controlling a transport route. In this method, generally, when the support is a thick photosensitive material, it is suitable for conveyance, and when the support is thin, the opposed roller type is preferable. In the case of a thinner support, it is preferable to install a large number of pairs of opposed rollers or to bond a photosensitive material to the rear end of the support (also referred to as a tab leader) for processing. Depending on the case, a feed mechanism (insertion mechanism) may be provided in the processing tank insertion part.

(3) When processing a photosensitive material, the exposed photosensitive material is joined to the rear end of the reader which is previously passed through the processing tank, and the radar is driven to wind the photosensitive material. However, this method is generally called cine-type development for photographic light-sensitive materials and leader trailer transport development for printing light-sensitive materials.
975) p. 70 and April issue (1975) p. 40 and May issue (1975) p. 36 and same June issue (1975)
p. 41. These processing methods require joining so-called long leaders before and after the light-sensitive material for processing, but are suitable when a large amount of print material needs to be produced. As a transportation method similar to this, (4) an endless leader belt method and an endless chain method are known. This method is described in the May issue of Photography Industry (1975) p. 36 and same June issue (1975)
p. 41. These methods are not suitable for the present invention because they bring in liquid and bring in much liquid.

In the method of (3) described above, the leader uses a short object instead of a long one, and this leader (also referred to as (5) short leader) is moved by a special drive, and as a result, the sensitive material is conveyed. The method is also used recently and is applicable to the present invention and is one of the preferred embodiments. This method includes (5-1) a belt (timing belt) having a large number of protrusions corresponding to the holes attached to the short leader.
This is a method of moving the short leader by the rotational movement of, and processing the sensitive material as a result. As another method (5-2), there is known a method in which the short leader is moved by rotation of a gear (sprocket) having a convex portion corresponding to a hole formed in the short leader, and the photosensitive material is processed. For example, the method described in JP-A-4-101139. This method is one of the preferable transportation methods. In particular, the method of transporting with a sprocket is preferable. As a method for processing a small amount of liquid as in the present invention, a belt transport method is disclosed in JP-A-2-6755.
1. JP-A-2-103043 discloses an endless belt method in JP-A-2-67550 and JP-A-2-58744.
However, Japanese Patent Laid-Open No. 1-154155 discloses a magnetic transfer method.
Japanese Patent Laid-Open No. 4-101139 is known as sprocket conveyance. Further, in the circulation system of the treatment liquid in the present invention, it is preferable that the treatment tank of the present invention is circulated for controlling the temperature and removing suspended matters. The circulation speed varies depending on the size of the processing tank, but is 0.1 per minute.
-30 liters, preferably 0.2-10 liters. If the circulation is too weak, the temperature control becomes difficult, and if it is too strong, the liquid may deteriorate or overflow.

In the circulation method of the present invention, the circulation system preferably sucks the tank liquid from the bottom of the processing tank and discharges it to the upper part of the tank. It is particularly preferable that the upper part of the tank is discharged to a place within a depth of 10 cm from the liquid surface. For the purpose of preventing the liquid from overflowing above the liquid surface due to pressure, a method of covering the vicinity of the liquid surface with a wiper blade or the like can be preferably used. At the same time, this wiper blade can also act as a squeegee.
As a pump, Iwaki magnet pump MD-1
0, MD-20, MD-30 and the like are preferably used.
Furthermore, by providing a powerful jet in the above circulation system, the processing liquid is applied to the film surface of the photosensitive material by jet stirring to obtain target photographic characteristics in a short time, accelerate desilvering, wash bath and stabilize. The washing out of various components in the bath can be promoted.

As a method of jet stirring, Japanese Patent Laid-Open No.

No. 199436 and the like. More specifically, the method of jet stirring in each treatment liquid is described in JP-A-62-62
No. 183460, lower right column, page 3 to lower right column, page 4, a method of discharging the liquid pumped by a pump from a nozzle provided facing the emulsion surface is preferable. As the pump, magnet pumps MD-10, MD-15, MD-20 manufactured by Iwaki Co., Ltd. can be used. The hole diameter of the nozzle is 0.3 to 2 mm, preferably 0.5 to 1.5 mm. Further, it is preferable that the nozzle is opened in a circular shape in a direction perpendicular to the chamber plate surface and the photosensitive material surface as much as possible, but the angle may be 60 to 120 degrees from the conveying direction side, and the shape may be a rectangle or a slit. .. The number of nozzles is tank capacity 1L
The number is 5 to 200, preferably 10 to 100. Further, if the jet flow strikes a portion of the photosensitive material unevenly, uneven development and residual color unevenness occur. Therefore, it is preferable to sequentially shift the positions of the nozzles so that they do not hit the same place. For example, a row of about 2 to 8 holes is arranged perpendicularly to the carrying direction and the positions thereof are gradually changed at appropriate intervals. If the distance from the nozzle to the photosensitive material is too short, the above unevenness is likely to occur, and if it is too far, the stirring effect is weakened.
The thickness is preferably 0.5 to 12 mm, more preferably 1 to 9 mm. The flow velocity of the liquid discharged from each nozzle similarly has an optimum range, preferably 0.5 to 5 m / sec.
Particularly preferably, it is 1 to 3 m / sec.

In the processor of the present invention, since the developing process is generally a chemical reaction, it is possible to stabilize the photographic performance by controlling the temperature during the development at a designated temperature within a certain temperature fluctuation range. That's what you need to get to. Especially in an automatic processor, a person does not check the temperature, so stable temperature control is important. Such automatic temperature control and homogeneous control in the automatic processor is called temperature control (temperature control). In other words, the temperature control is a function for keeping the liquid temperature of the processing tank at a designated temperature and even. Therefore, the functions can be divided into a heating part (H), a cooling part (C) (this is not necessary in the case of air cooling), a part for circulating a liquid (J), and a temperature detecting part (S). . S is necessary for temperature control and is preferably installed in the processing tank.
(JP-A-1-170944) There are cases where the respective combinations of the functions of H, C, and J are carried out in a processing tank, a case where they are carried out in a separate tank, and an intermediate thereof.

In the small liquid treatment tank, H and J are preferably at least outside the treatment tank, and H is placed in a sub tank (air opening tank directly connected to the treatment tank), installed in a circulation path, or circulated. It is preferably installed in a hump tank (air unopened tank: replenishment mixing tank) installed in the route. As a pump used for circulation, an axial flow (propeller) pump, a so-called chemical pump is often used, but a screw pump, a gear pump, a piston pump and the like can also be used. The heater used for the heating part (H) is a stainless steel heater in which nichrome wire is embedded in an insulator, a ceramic heater that uses the heat of ceramics, a planar heater that uses the heat of carbon fibers, a cast heater (a volume heater There is a cavity in the heater and there is a method of heating by passing a temperature control liquid through this) (JP-A-62-246057). For this purpose, a method of incorporating a heater into a circulation system using a cast-in heater is a liquid amount. Is the most preferable method because the increase of
This casting heater is disclosed in JP-A-5-80479 and JP-A-5-80479.
-204117 has detailed description.

The circulation flow for efficiently controlling the temperature of the small liquid amount treatment tank is in accordance with the circulation method described above.
As shown in FIG. 1 of 83251, for example, in the case of a U-shaped slit type treatment tank, it is preferable to take out the liquid from the lower part of the U-shape and return it to the upper part of the U-shape on both sides. When returning as shown in this figure, it is most preferable to blow out with a nozzle having slits in the width direction of the photosensitive material so that the liquid can be uniformly sprayed over the entire width of the photosensitive material. Further, when the liquid is taken out from the upper part of the U-shape and returned to the upper part of the other U-shape and there is a sub tank, it is generally preferable to take out the liquid from the sub-tank side in order to stabilize the temperature control. In this case, it is advisable to install a blade for preventing liquid spouting on the upper part of the liquid surface on the returning side. For example, the wiper member 78 of FIG. 2 of JP-A-3-257450 is preferable. In this case, if the temperature control is stabilized in the sub tank, it is not necessary to install a blade for preventing liquid outflow in the circulation method of taking out from the upper portion of the U-shape without the sub tank.

Control is also required to keep the temperature constant. There are controls such as temperature reduction when the sensitive material enters the liquid and when it is replenished, control for preventing heating of the heater, energy saving control, outside temperature prediction, and the like. For example, JP-A-58-211149, JP-A-62-238556, JP-A-62-238557, JP-A-62-246058,
JP-A-1-177542, JP-A-1-200421, JP-A-1-214850 and the like.

It is preferable that the processor of the present invention has a function of being replenished in accordance with the processing amount of the exposed light-sensitive material. Various methods can be adopted as the replenishment method.
For example, as described in JP-A-5-173299, a method of directly replenishing a circulating concentrated solution, JP-A-6-19481.
A method of stocking a concentrated solution in a stock tank once and then replenishing it as described in JP-A No. 64-55560.
As described in JP-A-3-134666, a completion replenisher solution system in which a cartridge of the completion solution is directly replenished to a tank as described in JP-A-64-55561 and 64-55562.
A method in which a replenisher is automatically supplied from a cartridge to a stock tank and then replenished to a processing tank, EP-5
A method of directly replenishing a concentrated liquid and water into a tank as described in 90583A1, JP-A-5-188533 and 6-202.
297, 7-169339, etc., and the method of replenishing the solid processing agent and water.

In the processor of the present invention, since the opening area of the liquid surface is relatively small, it is preferable to provide a circulation system or a sub-tank for the replenishment, and replenish at that location. In addition, when replenishing to the circulation system, it is also a preferable method to provide a bulge in a part of the circulation path (hump tank) and replenish to that portion. A replenishing pump is used for replenishing the processing liquid, and a bellows type replenishing pump is preferable. Further, as a method of improving the replenishment accuracy, it is effective to supplement the diameter of the liquid feeding tube to the replenishment nozzle in order to prevent backflow when the pump is stopped. Preferred inner diameter is 1-8m
m, particularly preferably 2 to 5 mm.

Although various parts materials are used in the automatic processor of the present invention, preferred materials are described below. A modified PPO (modified polyphenylene oxide) resin and a modified PPE (modified polyphenylene ether) resin are preferable as a tank material such as a processing tank and a temperature control tank, and as a material for guides of the processing rack and the liquid contact part. Examples of the modified PPO include "Noryl" manufactured by GE Plastics Co., Ltd., and modified PPE include "Zylon" manufactured by Asahi Kasei Kogyo Co., Ltd. and "Yupiace" manufactured by Mitsubishi Gas Chemical Company. These materials have excellent chemical resistance to a developing solution, a fixing solution, a bleach-fixing solution and the like. These materials are suitable for injection molding and have an advantage that various hollow molding such as low foam molding, sympress molding, and gas counter pressure molding can be performed. By using these molding methods, it is possible to integrally mold the processing tank and the temperature control tank and the guides and racks with a complicated structure. It became possible to make. It can also be used for large housing members such as covers for automatic processors by engineering blow molding. Since these materials have a higher heat resistance temperature than general ABS, they can be used as a material for drying members of an automatic processor. Further, when heat resistance or steel property is required, glass fiber reinforced or filler added grade can be used.

Further, ABS (acrylonitrile-butadiene-styrene resin) has chemical resistance to processing solutions (for example, color developing solution, bleaching solution, fixing solution and bleach-fixing solution), so that it is less likely to occur. It can be used for parts and racks. ABS resin from each company such as "Denka" manufactured by Denki Kagaku Kogyo, "Psycholac" manufactured by Ube Industries, Mitsubishi Monsanto Kasei, and Japan Synthetic Rubber can be used. ABS is 80 ℃
It is preferably used in the following environment. Further, ABS is a material suitable for the housing of an automatic processor because it has good moldability by injection molding, has few sink marks during molding, and can be molded with good flatness. This material is also suitable for the processor supply section and cassettes.

The olefin resins PE (polyethylene) and PP (polypropylene) have high chemical resistance to general processing solutions (for example, color developing solution, bleaching solution, fixing solution, stabilizing solution). There is. PE has many products such as Showa Denko and Ube Industries. PP is Ube Industries, Chisso,
There are many products such as Mitsui Toatsu Chemical and Asahi Kasei. It is used as a material for replenishment tanks and waste liquid tanks in automatic processors. Since the material is inexpensive and the large-sized tank can be easily manufactured by hollow molding, it can be preferably used in a portion that does not require high dimensional accuracy.

PVC (polyvinyl chloride resin) is
It has excellent chemical resistance, is inexpensive and can be easily welded, and has excellent workability. Many types of PVC are produced by many companies, such as various chemical manufacturers such as the electrochemical industry and Riken Vinyl Industry. Sheet materials extruded from Takiron Industrial "Taquilon Plate" and Mitsubishi Plastics "Hishi Plate" are commercially available, and various modified PVCs are also commercially available and can be easily used.
Acrylic-modified PVC is commercially available from in-cylinder plastic “Kyduck” and Sunarrow Chemical. Acrylic modified PVC has a smooth surface and good water repellency, and when used in a tank, it is a suitable material that does not easily cause precipitation of a processing solution (eg, precipitation of a main agent from a color developing solution). As a device for extruding PVC or smoothing the surface of an injection-molded article, it is highly effective to add soybean oil or the like in addition to modified PVC to improve the fluidity during molding. The addition of soybean oil (preferably modified soybean oil) not only smoothes the resin surface and does not impair the quality of the photosensitive material due to scratches, but also has the effect of improving the fluidity during molding.

As a material for the guide of the processing tank or the processing section in order to prevent the deposition of the color developing agent or the like and to improve the transportability of the light-sensitive material,
Crystalline polymers can be used. PBT (polybutylene terephthalate), HDPE (ultra high density polyethylene resin), PTFE (polytetrafluoroethylene resin),
PFA (ethylene tetrafluoride / perfluoroalkoxy ethylene resin), PVDF (polyvinylidene fluoride resin)
And the like are suitable for a guide in contact with a photosensitive material and a liquid interface portion where a processing liquid (for example, a color developing solution) is likely to be deposited. The above-mentioned fluoride is effective even if it is coated on another material such as PPE.

The material of the roller of the processing section is PVC
(Polyvinyl chloride resin), PP (Polypropylene), P
Thermoplastic resins such as E (polyethylene), UHMPE (ultra high molecular weight polyethylene), PMP (polymethylpentene), PPS (polyphenylene sulfide), modified PPO (modified polyphenylene oxide), modified PPE (modified polyphenylene ether) are suitable. . PP, P
Olefin resins such as E and PMP can be injection-molded smoothly on the roller surface, and since the specific gravity is small, the rotational load can be reduced, and thus the emulsion surface of the conveyed photosensitive material is less likely to be scratched and suitable. These are often used for rollers in the turn section. UHMPE or PTFE (PFA or P
Materials such as (including VDF) are suitable for the portion where the photosensitive material slides and the portion where the processing liquid requires water repellency. It has the effect of preventing the sensitive material from being scratched by the solidified portion of the treatment liquid deposited on the roller.

The roller provided with these materials on the roller surface (including coating) is suitable for the roller located at the interface of the treatment liquid and the roller for the squeeze portion. P
VC is suitable because it is easy to process into a roller by extrusion molding. Further, it is preferable that the roller having a soft resin portion having a low hardness on the surface of the roller can be easily manufactured by the double extrusion molding, and the roller can be brought into soft contact with the photosensitive material. In addition to PVC, modified PPO, modified PPE, modified PPS, etc., have high rigidity for the rollers that carry conveyance force.
It is suitable because it can withstand high rotational torque.
It is preferable to use glass fiber-reinforced or mineral-added strengthening agents such as mica, talc and potassium titanate in order to further enhance rigidity. By adding the reinforcing material, the bending elastic modulus of the roller is improved, creep deformation due to aging can be prevented, and the roller can be prevented from bending over a long period of use and stable transportability can be secured. Further, by adding an inorganic substance to the resin and molding, the surface can be roughened by the inorganic particles appearing on the roller surface to prevent it from slipping.
The surface roughness of the roller can be controlled by adjusting the particle size and the amount of the added inorganic material.

The thermosetting resin is suitable for a carrier roller having a small diameter and a photosensitive material having a wide width and a long roller length. PF (phenolic resin), thermosetting urethane resin, and unsaturated polyester resin are preferable. Epoxy resins are also suitable for some processing solutions other than alkaline processing solutions. The PF is preferably a resol type, and Mitsui Toatsu Chemicals “OR-85” is particularly suitable. Graphite may be added for reinforcement. Since this roller can be made thin (for example, the outer diameter is 8 mm), the processing rack can be downsized.
As the thermosetting urethane resin, Nippon Unipolymer "Unilon", Dainippon Ink and Chemicals "Pandex", Takeda Chemical Industries "Takenate" and the like are suitable. A roller coated with a fluorine-containing resin is also preferable for preventing the contamination with the developer. Specifically, JP-A-4-16195
The resin disclosed in No. 5 can be used.

An elastomer can be used for the soft roller such as the nip roller. For example, olefin elastomers, styrene elastomers, urethane elastomers, vinyl chloride elastomers and the like are preferable. Gears and sprockets in the processing section include PA (polyamide), PBT (polybutylene terephthalate), and UHM.
Thermoplastic crystalline resins such as PE (ultra high molecular weight polyethylene), PPS (polyphenylene sulfide), LCP (whole aromatic polyester resin, liquid crystal polymer) and PEEK (polyether ether ketone) are suitable.

Examples of PA include polyamide resins such as 66 nylon, 6 nylon, and 12 nylon, as well as aromatic polyamides having an aromatic ring in the molecular chain and modified polyamides. Toray and DuPont “Zytel” are suitable as 66 nylon and 6 nylon, and Toray “Rilsan” and Daicel Hüls “Daiamide” are suitable as 12 nylon. Suitable aromatic polyamides include Mitsubishi Gas Chemical's "Renny" polyamide MXD6, and modified polyamides such as Mitsui Petrochemical's "Alen" modified polyamide 6T. PA is preferably a glass fiber reinforced or carbon fiber reinforced grade because it has a high water absorption rate and easily swells in the treatment liquid. Aromatic polyamides have a relatively low water absorption rate and thus are less likely to swell, and high dimensional accuracy can be obtained. In addition, high molecular weight products such as MC nylon obtained by compression molding can obtain sufficient performance without fiber reinforcement. In addition, oil-impregnated nylon resin such as "Polyslider" is also used.

Contrary to PA, PBT has a very low water absorption rate, and therefore has high chemical resistance to the treatment liquid. Toray and Dainippon Ink and Chemicals PBT and Nippon GE Plastics "Barox" are used. PBT is used depending on the site, whether it is a glass fiber reinforced product or an unreinforced product.
In order to improve the meshing of gears, it is preferable to use a glass reinforced product and an unreinforced product in combination.

As UHMPE, unreinforced products are suitable, and Mitsui Petrochemical's "Lubemer", "Hi-Zex Million", Sakushin Kogyo "New Light", Asahi Kasei "Sunfine", Dai Nippon Printing "Ultra High Molecular Weight Polyethylene UHM"
W "is suitable. As the PPS, those reinforced with glass fiber or carbon fiber are preferable. As LCP, ICI Japan "Victorex", Sumitomo Chemical "Econor",
Nippon Oil "Zyder", polyplastics "Vectra", etc. can be used. PEEK is a suitable material that has extremely good chemical resistance and durability against any processing liquid of the developing machine and is an unreinforced product and exhibits sufficient performance. Ultra-high molecular weight polyethylene or the like is preferable as the material of the bearing and the like.

The springs and springs used in the processing liquid of the automatic processor are usually stainless steel (SUS316),
Titanium pad is used. Plastic springs can be used if the spring or spring cannot be made properly with titanium. For applications where the amount of deformation when a load is applied is small (the critical strain of Hooke's law is 1.6% or less), PBT (eg Nippon GE Plastics “Barox 310” etc.), PP (eg Asahi Kasei “M-15”)

These homopolymers and copolymers can be synthesized according to conventionally known methods for producing polyesters. For example, when an acid component is directly esterified with a glycol component, or when a dialkyl ester is used as an acid component, first, a transesterification reaction is performed with the glycol component, and this is heated under reduced pressure to remove excess glycol components. By doing so, it can be synthesized. Alternatively, an acid component may be used as an acid halide and reacted with glycol. At this time, if necessary, a transesterification reaction, a catalyst or a polymerization reaction catalyst may be used, or a heat resistance stabilizer may be added. These polyester synthesis methods are described, for example, in Polymer Science, Vol. 5, “Polycondensation and Polyaddition” (Kyoritsu Shuppan, 1980), pp. 103-136.

According to the method described in No. 4, molding can be easily performed.

The glass transition temperature (Tg) in the present invention means a difference from a baseline when 10 mg of a sample film is heated in a helium nitrogen stream at a temperature of 20 ° C./min using a differential thermal analyzer (DSC). It is defined as the arithmetic mean temperature of the temperature at which eccentricity begins and the temperature returning to a new baseline.
However, when an endothermic peak appears, the temperature indicating the maximum value of the endothermic peak is defined as Tg. Although the polyester of the present invention has a Tg of 50 ° C. or higher, its use conditions are not generally handled with sufficient care, and there are many cases where the temperature is exposed to 40 ° C. especially outdoors in the middle of summer. From this viewpoint, the Tg of the present invention is preferably 55 ° C. or higher for safety. More preferably, Tg is 70 ° C. or higher, and particularly preferably 80 ° C. or higher. This is because the effect of curling improvement by this heat treatment disappears when exposed to a temperature exceeding the glass transition temperature, so that the temperature, which is a severe condition when used by general users, that is, the summer temperature exceeds 40 ° C. Polyesters having a glass transition temperature above the temperature are preferred. On the other hand, the upper limit of the glass transition temperature is 200 ° C. If the polyester has a glass transition temperature of more than 200 ° C., a film having good transparency cannot be obtained.

Next, examples of preferable specific compounds of the polyester used in the present invention are shown, but the present invention is not limited thereto. Examples of polyester compounds P-0: [terephthalic acid (TPA) / ethylene glycol (EG)) (100/100)] (PET) Tg = 80 ° C. P-1: [2,6-naphthalenedicarboxylic acid (NDCA) / ethylene Glycol (EG) (100/100)] (PEN) Tg = 119 ° C P-2: [terephthalic acid (TPA) / cyclohexanedimethanol (CHDM) (100/100)] Tg = 93 ° C P-3: [TPA / Bisphenol A (BPA) (100/100)] Tg = 192 ° C P-4: 2,6-NDCA / TPA / EG (50/50/100) Tg = 92 ° C P-5: 2,6-NDCA / TPA / EG (75/25/100) Tg = 102 ° C. P-6: 2,6-NDCA / TPA / EG / BPA (50/50/75/25) Tg = 12 ° C P-7: TPA / EG / BPA (100/50/50) Tg = 105 ° C P-8: TPA / EG / BPA (100/25/75) Tg = 135 ° C P-9: TPA / EG / CHDM / BPA (100/25/25/50) Tg = 115 ° C. P-10: IPA / PPDC / TPA / EG (20/50/30/100) Tg = 95 ° C. P-11: NDCA / NPG / EG ( 100/70/30) Tg = 105 ° C. P-12: TPA / EG / BP (100/20/80) Tg = 115 ° C. P-13: PHBA / EG / TPA (200/100/100) Tg = 125 ° C. P-14: PEN / PET (60/40) Tg = 95 ° C. P-15: PEN / PET (80/20) Tg = 104 ° C. P-16: PAr / PEN (50/50) Tg = 142 ° C. P- 17: PAr / PC T (50/50) Tg = 118 ° C. P-18: PAr / PET (60/40) Tg = 101 ° C. P-19: PEN / PET / PAr (50/25/25) Tg = 108 ° C. P-20: TPA / 5-sulfoisophthalic acid (SIP) / EG (95/5/100) Tg = 65 ° C

The polyester support (film base) preferably has a thickness of 50 μm or more and 100 μm or less.
If it is less than 50 μm, it cannot withstand the storage stress of the photosensitive layer generated during drying, while if it exceeds 100 μm, it is inconsistent with the purpose of reducing the thickness for compactness. However, when used as a sheet-shaped photosensitive material,
It may have a thickness of more than 100 μm. Its upper limit is 300 μm. All of the polyesters of the present invention as described above have a flexural modulus higher than that of TAC, and it was possible to realize the original thinning of the film. However, among these, PET had strong flexural elasticity,
PEN is used, and it is possible to reduce the film thickness required for TAC of 122 μm to 100 μm or less.

The polyester support of the present invention is preferably subjected to a heat treatment, but at that time, it is necessary to perform the treatment at a temperature of 40 ° C. or higher and lower than the glass transition temperature for 0.1 to 1500 hours. This effect progresses faster as the heat treatment temperature is higher.
However, when the heat treatment temperature exceeds the glass transition temperature, the molecules in the film move rather disorderly and conversely the free volume increases, so that the molecules easily flow, that is, the film is easily curled. Therefore, this heat treatment needs to be performed below the glass transition temperature. The heat treatment referred to in the present invention is performed after being formed as a support, that is, after being stretched and solidified, after being lowered to about room temperature, for example, once lower than 40 ° C., and before the undercoat layer is applied. Alternatively, it is preferable that after the undercoat layer is applied, a separate heat treatment is carried out after the temperature is lowered to room temperature, for example, a temperature of less than 40 ° C. and before the coating of the silver halide photosensitive layer.

It is desirable to carry out this heat treatment at a temperature slightly below the glass transition temperature in order to shorten the treatment time.
The glass transition temperature is 0 ° C or higher and lower than the glass transition temperature, and more preferably 30 ° C below the glass transition temperature or higher and lower than the glass transition temperature. More preferably, it is not lower than the glass transition temperature and lower than the glass transition temperature by 15 ° C. On the other hand, when heat treatment is performed under these temperature conditions, an effect is recognized after 0.1 hour. Further, at 1500 hours or more, the effect is almost saturated. Therefore, it is preferable to perform the heat treatment for 0.1 hour or more and 1500 hours or less.

In the method of heat-treating the polyester of the present invention, after heating to Tg or more for a short time in advance to shorten the time (preferably, Tg is treated at 20 ° C. or higher and 100 ° C. or lower for 5 minutes to 3 hours). Alternatively, the heat treatment may be performed at 40 ° C. or higher and lower than the glass transition temperature. Further, in the heating method, the film roll may be left as it is in a heating warehouse for heat treatment, or it may be further conveyed to a heating zone for heat treatment. The latter is preferable in consideration of manufacturing suitability. Further, the roll core used in the heat treatment preferably has a structure in which an electric heater is built in or a high-temperature liquid can be poured so that the film can be hollow or heated in order to efficiently propagate the temperature to the film. The material of the roll winding core is not particularly limited, but it is preferably one that does not undergo strength reduction or deformation due to heat, and examples thereof include stainless steel and glass fiber-containing resin.

Further, a drying fan 22 is arranged on the open end side of the last stabilizing tank 16, and the negative film F coming out of the stabilizing tank 16 is inserted into the drying fan 22 and dried. Further, the photosensitive material processing apparatus 10 is provided with a cover (not shown) that entirely covers each processing tank. Among these processing tanks, for example, the color developing tank 12

To As shown in FIG. 3, in the space 12C in the color developing tank 12, the guide portion 12B, which is a part of the inner wall surface of the color developing tank 12, conveys the negative film F while being guided. 12B is formed in a slit shape. That is, the space 1 in the color developing tank 12
The width of 2C in the width direction is made slightly larger than the width of the negative film F, and the thickness of this space 12C is made slightly thicker than the thickness of the negative film F.

Further, in the wall portion 12A at the central portion in the width direction of the color developing tank 12, a concave portion 26, which is a depression on both upper and lower surfaces in FIG. The inner wall surface of the color developing tank 12 does not come into contact with the image forming portion.

As described above, the color developing tank 12 is a slit-shaped tank, the tank capacity of the color developing tank 12 is V milliliter, and the negative film F is brought into contact with the developing solution from the position where the negative film F starts to come into contact with the developing solution. When the path length, which is the transport distance to the position where the film F is discharged, is Lcm, the value of V / L is set to 25 or less to reduce the amount of the developer. Here, the tank volume excludes the volume of the liquid in the circulation system and the volume of a sub-tank that may be used for controlling the temperature of the developing solution. Further, slit-like spaces are similarly formed inside other processing tanks such as the bleach-fixing tank 14 and the stabilizing tank 16, and the above-mentioned connecting members 18A, 1
Similarly to the color developing tank 12, 8B, 18C, and 18D are also formed in a V shape having a slit-shaped passage therein, and are joined to the color developing tank 12, the bleach-fixing tank 14, and the three stabilizing tanks 16. Are arranged in an inverted U shape.

As shown in FIGS. 2 and 4, the color developing tank 1

Inside these bulging portions 28, a pair of conveying rollers 30 as conveying means having drive wheels 30A at both ends are arranged rotatably facing each other. Therefore, when the pair of transport rollers 30 is rotated, the perforation portion of the negative film F is sandwiched between the drive wheels 30A of the pair of transport rollers 30 while the negative film F is transported through the transport path T in the color developing tank 12. Will be transported along. A disk-shaped magnet 32, whose magnetic poles are arranged so as to be aligned along the circumferential direction, is attached to one of the drive wheels 30A of the transport rollers 30. The color developing tank 1 facing the magnet 32 of the pair of conveying rollers 30 with the wall portion 12A of the color developing tank 12 therebetween.

Similarly, disk-shaped magnets 36 are arranged so that magnetic poles are arranged along the circumferential direction, and gears 38 meshing with each other are attached to the other ends of the pair of transmission rollers 34, respectively. ing.

Further, a sprocket 42 is attached to the tip of the rotary shaft 40 protruding from the other end of the one transmission roller 34. Also, the bleach-fixing tank 14 and the stabilizing tank 1
Similarly, a plurality of bulging portions 28 each having a pair of conveying rollers 30 built therein are formed in other processing tanks such as 6, and a pair of transmission rollers 34 having a sprocket 42 are also formed in these bulging portions 28. Are arranged respectively. Then, each sprocket 42 is provided over the entire photosensitive material processing apparatus 10.
A chain 44 is wound around the chain 44, and a motor 46 arranged in the photosensitive material processing apparatus 10 causes the chain 44 to be wound around.
Will be driven and rotated.

As described above, as the chain 44 is rotated by the motor 46, one transmission roller 34 having the sprocket 42 is rotated, and the other transmission roller meshed with the gear 38 is correspondingly rotated. 34 is also rotated. As a result, the magnets 3 of the pair of transmission rollers 34 are
The magnet 32 of the conveying roller 30, which faces 6 through the wall 12A of the color developing tank 12, is affected by the magnetic force, and the pair of conveying rollers 30 having the magnet 32 rotate together with the pair of transmission rollers 34. .

On the other hand, as shown in FIG.
A pipe 52, which is a circulation path, is arranged so as to connect the central portion, which is the lowermost portion, to the portion of the color developing tank 12 near the introduction and discharge sides. A pump 54 for sending the developing solution from the central portion of the color developing tank 12 to the portion near the introduction side of the color developing tank 12 and the portion near the discharge side of the color developing tank 12 is installed in the middle of the pipe 52. ing. Further, a casting heater 56 that heats the developer sent by the pump 54 to a predetermined temperature is installed at a position of the pipe 52 on the downstream side of the pump 54. Further, the pipe 52 is branched at a position downstream of the casting heater 56 of the pipe 52 so as to be connected to a portion near the introduction side of the color developing tank 12 and a portion near the discharge side of the color developing tank 12. .

To the portion of the pipe 52 on the downstream side of the pump 54, one end side of a pipe 58 which is a replenishing passage passing through the casting heater 56 similarly to the pipe 52 is connected, and the other end side of the pipe 58 is connected. It is connected to a replenishment tank 60 that stores a replenisher. A pump 62 for sending the replenishing liquid in the replenishment tank 60 to the pipe 52 is arranged in the middle of the pipe 58. Therefore, the casting heater 56
Will also heat the replenisher delivered by the pump 62. Here, the cast-in heater 56 is disclosed in JP-A-5-80.
As disclosed in Japanese Patent Publication No. 479 and Japanese Patent Laid-Open No. 5-204117, a heater and a piping pipe having good thermal conductivity are formed by being cast in a metal having good thermal conductivity together with a temperature sensor. The heat is rapidly and efficiently transferred to the developer and the replenisher passing through the piping pipe, so that the temperature of the developer in the color developing tank 12 can be maintained at a constant temperature. And this temperature sensor is connected to the pipe 5.
The temperatures of the developing solution and the replenishing solution flowing in the units 2, 58 are detected, and the operating state of the casting heater 56 can be adjusted based on the temperatures detected by the temperature sensor for the developing solution and the replenishing solution.

The length of the circulation system pipe 52 is shortened as much as possible to minimize the amount of the developer solution held in the pipe 52, thereby circulating the developer solution for maintaining the solution temperature. The amount of the developer can be reduced to a necessary minimum to reduce aerial oxidation of the developer. On the other hand, a prescribed amount of the replenisher is sucked from the replenisher tank 60 by the replenisher pump 62, and the replenisher is supplied to the color developing tank 12 through the pipe 58 of the replenishing system. When passing through a piping pipe (not shown), the temperature of the developer in the color developing tank 12 is raised to the same temperature. It should be noted that the piping pipe in the casting heater 56 of the replenishment system has a pipe line length long enough for the replenisher to rise to a predetermined temperature while passing through the piping pipe. The timing of replenishing the replenisher is just before the negative film F to be newly processed is inserted into the color developing tank 12, and at this time, the replenishing pump 62 is operated to replenish a prescribed amount of the replenisher and further processing is in progress. Replenish as needed.
Therefore, when processing the negative film F, the color developing tank 12
The quality of the developer inside is always kept constant. Then, the replenisher is supplied to the upper part of the color developing tank 12 in which the negative film F is inserted together with or independently of the developer circulating in the color developing tank 12.

The developer in the color developing tank 12 temporarily increases by the amount supplied with the replenisher, but the negative film F
With the above process, the increased amount is discharged from the color developing tank 12. However, an overflow waste liquid port (not shown) may be provided at the exit side of the negative film F of the color developing tank 12, and the increased amount may be discharged from this overflow waste liquid port and stored in a waste liquid tank (not shown). The replenisher is stored in a replenishment tank 60, which is a flexible closed container as described in JP-A-4-128841, and the replenisher contained therein is sucked out by a replenishment pump 62. The replenishment tank 60 becomes flatter as it goes. Therefore, air does not enter the replenishment tank 60 to oxidize the replenishment solution, and the initial quality of the replenishment solution in the replenishment tank 60 can be maintained for a long time until it is used up.

Next, FIG. 5 shows a sectional view of a second embodiment of a suitable photosensitive material processing apparatus which can be used in the method of the present invention. As shown in FIG. 5, the photosensitive material processing apparatus 100 according to the present embodiment is provided with a slit-shaped processing path 120 for reducing the processing liquid amount and simply processing. The slit-shaped processing path 120 used here is a cross section obtained by cutting a path in a processing tank through which a photosensitive material passes at a right angle to the traveling direction of the photosensitive material, and the cross-section has a thickness relative to the lateral width (width direction of the photosensitive material). Means a so-called slit type. The slit shape may be rectangular or oval. Here, in this processing tank,
When the thickness of the tank cross section orthogonal to the traveling direction of the photosensitive material is W, it is preferable that the condition of 0.1 ≦ W ≦ 5 cm is satisfied, and more preferably 0.2 ≦ W ≦ 4 cm,
More preferably, 1 ≦ W ≦ 3 cm. Further, in the processing tank, when the curvature formed by the processing path at the bottom of the processing tank is R, 10 ≦ R ≦ 70 mmφ is preferable, and further 20 ≦ R ≦ 50 mmφ is preferable.

The path length of the processing path 120 is determined according to the type of processing liquid and the time required for processing (immersion time in the processing liquid). The slit-shaped processing path 120 may be provided in all the processing tanks of the processing machine, or may be provided in a part of the processing tanks and the other processing tanks may be the same processing tanks as the conventional ones. In this photosensitive material processing apparatus 100, all processing tanks are provided with slit-shaped processing paths 120, and a color developing tank 140 and a bleach-fixing tank 160 having a path length according to the processing time.
Are adjacently arranged, and the photosensitive material developed in the color developing tank 140 is sent out to the bleach-fixing tank 160 which is the next processing tank by a pair of conveying rollers 180. Further, adjacent to the bleach-fixing tank 160, three stabilizing tanks 200
Has a structure in which each is arranged. The developing solution is stored in the color developing tank 120, the bleach-fixing solution is stored in the bleach-bleach-fixing tank 160, and the three stabilizing tanks 20 are provided.
Stabilizing liquid is stored in each of 0. If desired, the bleach-bleach fixing bath 160 may be a separate bleaching bath and fixing bath. Therefore, when the photographed negative film F is inserted from the open end side of the color developing tank 140 of the photosensitive material processing apparatus 100, these color developing tanks 14 which are processing tanks are inserted.
The negative film F is dipped in the bleach-fixing tank 160 and the three stabilizing tanks 200 in this order to develop the negative film F. Further, a drying fan (not shown) is arranged on the open end side of the last stabilizing tank 200, and the negative film F coming out of the stabilizing tank 200 is inserted into the drying fan to be dried. Become.

As described above, the color developing tank 140 is a slit-shaped tank, the tank capacity of the color developing tank 140 is V milliliter, and the position where the negative film F starts to come into contact with the developing solution (processing tank inlet) When the path length, which is the distance from the inside of the developing solution to the position where the negative film F is discharged (outlet of the processing tank), is Lcm, the value of V / L is set to 25 or less, and the amount of the developing solution is reduced. ing. It should be noted that the tank volume (V) here excludes the volume of the liquid in the circulation system and the volume of the sub-tank or the like that may be used for temperature control of the developer. Further, a slit-like space is similarly formed inside the other processing tanks such as the bleach-fixing tank 160 and the stabilizing tank 200, and the color developing tank 140, the bleach-fixing tank 160, and the three stabilizing tanks 200 are joined together. Placed respectively.

Further, the conveying speed of the photosensitive material in this photosensitive material processing apparatus is preferably 0.1 m to 5 m per minute, more preferably 0.2 m to 3 m per minute,
It is particularly preferable that it is 0.3 m to 1.5 m per minute. Further, the method of conveying the photosensitive material applied to this processor is not particularly limited, and known methods such as a roller-type conveying method for conveying the photosensitive material by the nip force of a pair of conveying rollers, and a narrow rotation due to rotation of the drum are used. It is possible to select a drum processing method, a so-called leader trailer transfer method, or the like, in which a photosensitive material is inserted, transferred, and sent out in the processing liquid held in the gap, depending on the purpose.

By using such a photosensitive material processing apparatus, a color developing tank 140 having a slit-shaped processing path is provided.
Since the conveyance path of the negative film F is constituted by the processing path 120 having an extremely small thickness, the amount of the developer can be reduced as compared with the conventional color developing tank 140, and a large amount of replenisher can be added to maintain the characteristics of the developer. Since no liquid is required, the running cost of the photosensitive material processing apparatus 100 is reduced. Also,
By reducing the amount of the developing solution in the above structure, the color developing tank 140 that stores the developing solution can be downsized, and accordingly, the photosensitive material processing apparatus 100 can be downsized. And
Other processing tanks such as the bleaching tank 160, the fixing tank 180, and the stabilizing tank 200 will operate in the same manner as above.
