Field of the Invention The present invention relates to a method of processing a photosensitive material for photographing and a processing apparatus therefor, and more specifically, it realizes both shortening of processing time and downsizing of a processing machine, good photographic characteristics, and conveyance.

2. Description of the Related Art Photographic materials for photography (hereinafter also referred to as "photosensitive materials")
After exposure, the color development is generally carried out by color development, desilvering, washing with water and stabilization. In these processes, various research
It has been developed and improved. Above all, recently, there has been a demand for speeding up the processing and downsizing the processing machine. However, no great progress has been made in the processing method and processing apparatus for processing these photosensitive materials. In particular, no major progress has been made in reducing the size of the processing equipment and shortening the processing time.

The desilvering step among the processing methods of the light-sensitive material is roughly classified into two methods, that is, a processing method in which bleaching and fixing are separated and a processing in which a bleach-fixing solution having two functions is combined. be able to. The light-sensitive material for photographing has a larger amount of coated silver and various additives than those of the printing material, and silver iodobromide is mainly used. Therefore, the desilvering load is high, and in particular, the fixing process is heavy and the processing time is long. In particular, in continuous processing such as running processing, a generally long processing (generally, in the case of a negative film, the total processing time is 17 Minutes to 30 minutes, and in the case of color reversal films, the total processing time is 45 minutes to 90 minutes). Therefore, it has been difficult to shorten the processing time of the photosensitive material for photographing.

One of the difficulties in downsizing of the processing machine for the light-sensitive material is due to the nature of the light-sensitive material itself, especially the conventional support, and it is impossible to use a roller having a very small radius of curvature. The above-mentioned photographic light-sensitive material had a large amount of coated silver and could not shorten the development reaction time.

On the other hand, various developing methods for such a light-sensitive material have been known for a long time (Photografic & Engine
ering 5 , 48-54 (1961)). Among them, the method of automatically and efficiently developing a photographic light-sensitive material having a high coating amount of silver is processed while drawing a sine curve (sinusoidal) of, for example, a roller-conveying type automatic developing machine, a return belt-conveying type or a leader-conveying type. It is a processing method. In this method, the photosensitive material is processed while drawing a sine curve (or U-shaped) curve in one processing tank, so that the processing machine can be designed compactly in any place. In this case, in order to achieve both the shortening of the processing time and the compactness of the processing machine, the conveying speed (S) m / min is increased and the curvature (R) m of the U-shaped portion is decreased. However, from the viewpoint of transporting the photosensitive material, S and R are not mixed,
It was not possible to achieve both shortening the processing time and making the processing machine compact.

Further, US Pat. No. 4,947,196 and International Publication No. 90/04254, and recently JP-A-4
-68336, JP-A-4-73737, JP-A-5-
No. 88283 discloses, as a new photographic system, a photographing camera having a roll-shaped film having a magnetic layer containing magnetic particles for enabling magnetic recording on the back surface of a photographic film and a magnetic head. According to this technology, it is possible to magnetically input / output on the film the identification information of the type and manufacturer of the photosensitive material, the information about the photographing condition, the information about the customer, the information about the print condition and the print reprint condition in the magnetic layer. As a result, it is possible to improve the print quality, improve the efficiency of printing work, and improve the efficiency of laboratory work processing. Further, in this system, there is a demand for making the camera compact, and therefore, Japanese Patent Laid-Open Nos. 6-35118 and 6-35118
It is said that it is better to use a thin support as shown in Japanese Patent Laid-Open No. 175282 and JIII Journal of Technical Disclosure 94-6023.

In the case of processing a light-sensitive material having a magnetic layer as described above, when the processing time is lengthened in order to complete desilvering processing, not only the magnetic characteristics deteriorate, but also the photographic characteristics deteriorate. It has happened. On the contrary, when the processing time was shortened, desilvering processing became insufficient and the photographic characteristics deteriorated. Furthermore, if the processing temperature is increased to accelerate the reaction such as desilvering, the members used for transporting the sensitive material deteriorate, and the transportability of the sensitive material deteriorates.

[0008]

Therefore, there is a demand for a technique which can shorten the processing time, downsize the processing machine, and have sufficient photographic characteristics, which has not been solved by the above-mentioned techniques. It was In particular, there has been a strong demand for solving these problems in the light-sensitive material having the magnetic recording layer. Therefore, an object of the present invention is to solve the problems of the above-mentioned conventional techniques, to achieve both reduction of processing time and compactness of a processing machine, and further, good photographic characteristics and good transportability. Another object of the present invention is to provide a method of processing a photosensitive material for photographing and a processing device thereof. Another object of the present invention is to achieve both shortening of processing time and downsizing of a processing machine, and further, without deteriorating the S / N ratio of magnetically recorded information of a photosensitive material having a magnetic recording layer and taking a photograph. An object of the present invention is to provide a processing method and a processing apparatus for a photosensitive material for photographing having good characteristics and good transportability.

[0011]

According to the present invention, the transport speed when the average gradation (γ) of a processed light-sensitive material is standardized to 1 is set within the above specific range, and the processing time of the light-sensitive material is further specified. As a result, not only the processing time can be shortened, but also a small processing device can be applied. By changing the temperature of the processing liquid and setting the processing time and the transfer speed within a specific range, the transfer distance (L) of the processing apparatus can be set short. As will be described later, if the photosensitive material conveying distance L becomes shorter, it can be applied to a small-sized device. Further, by processing the photosensitive material by setting the above-described specific transport speed and the specific processing time in which γ is standardized to 1, a sufficient color image can be obtained. For example, when printing on a color paper with a color negative film, or when projecting with a color reversal film or when performing reverse color printing, a sufficiently pleasing image can be obtained. By setting the above-mentioned carrying speed and processing time, the processing can be carried out without raising the processing temperature so much, so that the carrying failure due to the deterioration of the carrying member can be prevented. In the present invention, the temperature of the treatment liquid is preferably 33 ° C to 55 ° C, more preferably 35 ° C to 50 ° C, and further preferably 36 ° C to 4 ° C.
It is 7 ° C.

The transport speed (S) when the average gradation (γ) of the processed photosensitive material is normalized to 1 is 0.16 m / min ≦
S ≦ 0.84 m / min, preferably 0.36 m / min ≦ S ≦ 0.72 m / min. When the average gradation (γ) of the processed light-sensitive material is normalized to 1, the processing time of the light-sensitive material is 4.9 to 25.6 minutes, preferably 9.7 to 1
It is 9.3 minutes. Further, it is preferable to appropriately set the transport speed and the processing time when the average gradation (γ) is standardized to 1, depending on the type of the photosensitive material to be processed. For example, in the case of a color negative film, the transportation speed is 0.16 m / min.
The processing time is preferably 0.84 m / min and the processing time is 4.9 to 25.6 minutes. In the case of a color reversal film, the transport speed is 0.36 m / min to 0.72 m / min, and the processing time is 9.7.
~ 19.3 minutes is preferred. Here, in the present invention, the average gradation (γ) is the slope of the straight line portion connecting the points of (minimum density +0.1) and (maximum density −0.2) in the characteristic curve of sensitometry. Say.

In the present invention, the actual transport speed (S)
Is expressed as L / T, where L is the transport distance from the time when the photosensitive material is first immersed in the processing liquid to the outlet of the drying process, and T is the processing time of the photosensitive material between the transportation distances. In the present invention, the transport speed or the processing time when the average gradation (γ) of the processed photosensitive material is normalized to 1 means the same gradation (γ = 1) in various color photosensitive materials for photographing. It means the conveying speed or processing time when trying to obtain. For example, in the case of a color negative film, the average gradation (γ) is usually set to 0.6 for color printing. In order to make the gradation equal to 1, the processing time is (processing time) ÷ 0.6, and the carrying speed is (conveying speed) × 0.6. Also. In the case of color reversal film, it is usually the average gradation (γ) for viewing in the projected image.
Is set to 1.8. In order to make the gradation equivalent to 1, the processing time is (processing time) /1.8, and the carrying speed is (conveying speed) × 1.8. In the present invention,
By standardizing the transport speed and the processing time in this way, it becomes possible to comprehensively set the processing conditions for various color photosensitive materials for photographing.

In the present invention, in addition to shortening the conveying distance L of the photosensitive material processing apparatus, the diameter of the roller for conveying or for the nip of the photosensitive material is set to 1 to 5 cm, so that a smaller processing apparatus can be obtained. realizable. That is, as will be described later, since the size of the processing machine depends on the transport distance and the roller diameter, reducing both of them leads to further downsizing of the processing apparatus. The diameter of the roller is preferably 1.5 to 4 cm, more preferably 1.5 to 3 cm.

In the present invention, the effect of the present invention becomes more remarkable when it is used in a light-sensitive material having a magnetic recording layer. That is,
In the processing of a photosensitive material having a magnetic recording layer, it is more magnetic to process the photosensitive material of the processor in a shorter conveying time than the length of the conveying path in which the photosensitive material is processed, even if the processing temperature is high. It was found that the deterioration of the recording characteristics was small and the deterioration of the photographic property was small. Various analyzes of the magnetic recording characteristics revealed that when a processing solution was used for a time longer than the time required for complete desilvering, long contact with members in the processing path resulted in deterioration of the magnetic characteristics and further deterioration of photographic characteristics. Was found to occur.

Therefore, by processing the light-sensitive material having the magnetic recording layer at the above-mentioned specific transportation speed and transportation time, not only the processing time can be shortened, the apparatus can be made compact, the photographic characteristics can be improved, but also the processing time can be improved. By shortening, it is possible to prevent deterioration due to processing of magnetic characteristics such as magnetic reading error. That is, the transport speed, the processing time, and the configuration of the processing apparatus are appropriate, and the photographic characteristics and magnetic characteristics are compatible.

Further, by setting the film thickness of the support of the sensitive material to be 85 to 105 μm, which is thinner than the conventional one, the transportability of the sensitive material can be improved and the sensitivity of the sensitive material can be improved even in the compact device as described above. Photographic properties and magnetic properties are also improved. Heat-treated polyethylene naphthalate (PEN) is preferable as a material for the thin support. This makes it more rigid than cellulose triacetate or polyethylene terephthalate,
It is suitable for shortening the processing time and making the device compact.
Further, it also prevents deterioration of photographic characteristics and magnetic characteristics.

Next, the size of a U-shaped automatic developing machine will be described as an example of a processing device for a photosensitive material for photographing. The processor size can be expressed as width x height x depth. Here, the depth is the thickness of each processing tank × the number of tanks + the thickness of the drying section. The thickness of the processing tank is about twice as large as the curvature diameter of the U-turn portion that conveys the sensitive material so that the sensitive material can be processed without being damaged. Further, in the depth, the thickness of the drying portion is small, so that it can be omitted.

From these facts, the size of the processor is W (m), the width of the processor corresponding to the width of the photosensitive material, H (m) the height of the processor, and the curvature diameter of the U-shaped turn. Let D (m) and the number of processing tanks be N, the processing machine size (V) is the following formula (1)
become that way. V = W · H · 2D · N (1) Since the width W of the processing machine corresponding to the width of the photosensitive material is almost constant, the size of the processing machine is determined by H · 2D · N. It is determined by equation (2), and the curvature diameter of the U-shaped turn is designed by equation (3). The number N of the processing tanks is not less than 4 because the drying section is included in the color photographic light-sensitive material. 21 or more is usually unthinkable due to the required processor footprint. Therefore, it is represented by the following formula (4). 20 cm ≦ H ≦ 200 cm (2) 0.5 cm ≦ D ≦ 30 cm (3) 4 cm ≦ N ≦ 20 (4)

On the other hand, the transport distance L (m) at which the photosensitive material is processed
Is expressed by the following formula (5), where the distance from the time when the sensitive material is first dipped in the liquid to the time when the sensitive material is dried is shown. Here, the depth of the processing tank is h (m). Processing length (L)

[0021]

[Equation 1]

Here, the depth h of the processing tank is the height H of the processing machine.
Since it is smaller than the above, generally, a circulation pump (P), a heater (H), a filter (F), and a waste liquid tank (R) in the lower part of the processing tank are put therein, so that conceptually, h≈H / 2. Further, since the respective treatment tanks have almost the same depth, the equation (5) is L
= N (2h + πD). h is generally much larger than the roller diameter (D), and ignoring πD, L = 2Nh =
It becomes NH.

When the processor size is represented by L, V = 2
D ・ W ・ L. Here, W is a width when the photosensitive material is processed, and therefore is substantially constant, and the processing machine size V is determined by L and D. Due to the compactness of the processor, it is better that L is shorter and D is smaller. In the case of the present invention, the transport distance L can be shortened, and more preferably, the roller diameter can be reduced, so that the processing apparatus can be made compact.

As a processing apparatus to which the present invention can be applied, any type of processing machine can be used as long as it is a small-sized processing machine having at least one roller. The small-sized processing apparatus applicable in the present invention includes a roller transport type automatic developing machine, a leader type roll automatic developing machine, a leader belt transport type roll automatic developing machine, a short leader type automatic developing machine, a cine type automatic developing machine and the like. . Here, the diameter (D) of the roller portion is preferably small, and D is preferably 0.5 to 30 cm, more preferably 0.5 to 20 cm, and further preferably 0.8 to
It is 10 cm, particularly preferably 1 to 5 cm. Furthermore, if the transport distance (L) is constant, the transport speed when the average gradation (γ) of the processed photosensitive material is standardized to 1
0.16 m / min ≦ S ≦ 0.84 m / min, preferably 0.
The photosensitive material is preferably processed at 36 m / min ≦ S ≦ 0.72 m / min.

Among these, as a treatment method which is particularly effective when applied, there are an automatic developing machine having a belt conveying mechanism and a roller conveying automatic developing machine having a roller pair. Among these automatic developing machines, it is particularly suitable for an automatic developing machine having at least a roller for conveying a sensitive material and a roller for nipping the sensitive material.

Among the function items constituting the automatic processor, the important function for automatically supplying the processing liquid to the photosensitive material is as follows.
They are agitation to physically diffuse the treatment chemicals and temperature control to accelerate the chemical reaction. For more information on these,

V). From these viewpoints, JP-A-53-578
There are applications such as No. 35 and No. 61-153645.

From these viewpoints, JP-A-63-131138; 63-2160.

In the present invention, it is preferable that the stirring of each treatment liquid is strengthened as much as possible so that the effects of the present invention can be more effectively exhibited. As a concrete method of strengthening stirring,
JP-A-62-183460, JP-A-62-18346
No. 1, namely, a color negative film processor FF-230 manufactured by Fuji Photo Film Co., Ltd.
A method in which a jet of a processing solution is made to collide with an emulsion surface of a light-sensitive material as used in B, a method of providing a stirring effect by using a rotating means of JP-A-62-183461, and further provided in the solution. Examples thereof include a method of moving the photosensitive material (film) while bringing the wiper blade into contact with the emulsion surface to make the emulsion surface turbulent, thereby improving the stirring effect, and a method of increasing the circulation flow rate of the entire processing solution. Of these, the method of colliding the jet stream of the processing liquid is the most preferable, and it is preferable to adopt this method for all the processing tanks.

As the roller material of the processing section which describes the roller for transportation or the nip of the photosensitive material used in the present invention, PVC (polyvinyl chloride resin), PP (polypropylene), PE (polyethylene), UHMPE (ultra high) Molecular weight polyethylene), PMP (polymethylpentene), PPS (polyphenylene sulfide), modified P
PO (modified polyphenylene oxide), modified PPE
Thermoplastic resins such as (modified polyphenylene ether), PTFE (polytetrafluoroethylene resin), PFA (tetrafluoroethylene / perfluoroalkoxyethylene resin), PVDF (polyvinylidene fluoride resin) are suitable. Olefinic resins such as PP, PE and PMP can be injection-molded smoothly on the roller surface, and since the specific gravity is small, the rotational load can be reduced, so that the emulsion surface of the conveyed photosensitive material is not easily scratched and is suitable. These are often used for the rollers in the turn section. UHMPE and PTF
Materials such as E (including PFA and PVDF) 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 substance of the deposit of the treatment liquid on the roller. A 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. PVC is suitable for being easily processed into rollers by extrusion. Also,
A roller having a soft resin portion having a low hardness on the surface of the roller can be easily manufactured by double extrusion molding, and a soft touch can be brought into contact with the sensitive material, which is preferable. In addition to PVC, modified PPO, modified PPE, modified PPS, and the like are suitable for the roller having a conveying force because they have high rigidity and can withstand a high rotation 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 stable conveyance can be ensured without bending the roller after long-term use. 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 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 "Bandex", Takeda Chemical Industries "Takenate" and the like are suitable.

A roller coated with a fluorine-based resin is also preferable for preventing the contamination with the developer. In particular,
The resin disclosed in JP-A-4-161955 can be used. An elastomer can be used for a soft roller such as a nip roller. For example, olefin elastomers, styrene elastomers, urethane elastomers, vinyl chloride elastomers and the like are preferable. The diameter of the roller as described above is particularly preferably 1 to 5 cm.

In the present invention, any photographic color light-sensitive material that can be used can be used. For example, a color light-sensitive material using a negative silver halide or a negative silver halide is used. Examples thereof include a color reversal light-sensitive material that obtains a positive image by processing, a color light-sensitive material using positive type silver halide, and the like.

(2) Japanese Unexamined Patent Publication No. 6-308702 shown in FIG.
In the color negative developing machine of the publication, processing was performed while changing the conveying speed, the processing liquid temperature, the total processing time, and the standardized total processing time as shown in Table-6. The magnetic reading error rate at that time and whether or not the photograph was finished reasonably when printed on color paper from this negative was evaluated. This photographic evaluation is a very rough grasp, but it is an important factor in constructing a system.

For the magnetic read error rate, the coercive force, saturation magnetization, and squareness ratio of the coated material were measured using VSMP10-15P manufactured by Toei Industry Co., Ltd. after running for three months. Also, based on the results, signals were read at the same head and the same speed, and it was determined whether the signals were output correctly. The ratio of the number of error bits to the input number of bits was calculated. When the error rate is 10 ⁻⁴ or less, there is no practical problem, but when the error rate is 10 ⁻³ or more, the result is NG.
In addition, 10 ^-3 to 10 ^-4 is acceptable. In addition, as for the evaluation of the stability of conveyance, the one that could be stably conveyed during the processing was ○, and during the processing, the conveyance was partially unstable or the photosensitive material was slightly scratched, but the allowable range A sample was evaluated as Δ, and a sample that could not be conveyed at all during the treatment and the photosensitive material was scratched was evaluated as ×.

[0087]

[Table 6]

From the results shown in Table 6, it can be seen that (a) the magnetic read error rate is strangely deteriorated when the processing time is long and is not suitable for a film carrying magnetic recording like this film. When the processed film is analyzed, tar-like dirt is generated in the magnetic recording portion as the total processing time (T) becomes longer, which is expected to increase the magnetic read error rate. It is understood that the total processing time T is preferably T ≦ 16 minutes and the transport speed S ≧ 0.26 m / minute in order to perform magnetic reading without error.

(B) From the evaluation of photographic properties, it can be seen that the total processing time may be short or long. That is, 2.9 minutes ≤
T ≦ 16 minutes. The transport speed S is 1.4 m / min ≧ S ≧ 0.26 m / min.

(C) If the temperature is too high in view of the stability of processing conveyance, the conveyance of the photosensitive material will be deteriorated. This is 55 for hard PVC
It is said to be stable above ℃, but if stress remains for a long time, it is presumed that parts deteriorate and the sensitive material cannot be transported and processed. That is, the transport speed S is 1.4
≧ S.

As a comprehensive evaluation from the above (a), (b) and (c), the transport speed S is 1.4 m / min ≧ S ≧ 0.26 m /
Minutes are the most usable area. Generally, the gradation (γ) of a color negative is considered to be proportional to the color development time. That is, since S = L / T, γ is inversely proportional to S. Moreover, in order to print conveniently on a color paper, γ≈0.6, so a print that is harder or softer than this cannot be obtained. In general, a processing machine processes both a color negative film and a color reversal film, so it is better to standardize γ of the photosensitive material to 1 in order to determine the conditions of the processing machine. Therefore, if the processing speed required for setting the gradation γ of the processed photosensitive material to 1 is hypothesized (for correction), and γ is multiplied by S to obtain a constant range, 1.4 m / min × 0 0.6 ≧ S ≧ 0.26 m / min × 0.6 0.84 m / min ≧ S ≧ 0.16 m / min. Therefore, by setting this range, the magnetic characteristics, photographic characteristics,
It can be understood that all of the transportability can be satisfied, the processing can be performed in a short time, and the apparatus can be applied to a small device.

Example 2 Japanese Laid-Open Patent Publication No. 4-3454 on the variously treated supports of Example 1.
The reverse color emulsion layer of Sample 101 of Example 1 described in Japanese Patent Publication No. 8 was applied. With respect to the layer structure of the emulsion layers, the first layer is an antihalation layer, the second layer is an intermediate layer, the third to fifth layers are red-sensitive emulsion layers, and the seventh to ninth layers are green-sensitive emulsion layers. The 11th to 13th layers are blue-sensitive emulsion layers, the 14th to 15th layers are protective layers, and the 6th and 10th layers are intermediate layers.

The photosensitive material prepared as described above is used for 24 mm
The width of the photosensitive material is cut into 160 cm, and two perforations of 2 mm square are provided at a distance of 5.8 mm at a position 0.7 mm from one side width direction of the photosensitive material. By making these two sets provided at intervals of 32 mm, US Pat.
96, 887, FIG. 1-FIG. It was housed in the plastic film cartridge described in 7. For this sample, a head capable of inputting and outputting with a head gap of 5 μm and a number of turns of 2000 was applied from the coated surface side of the magnetic recording layer as in Example 1 at a feed rate of 100 mm / s during the perforation of the photosensitive material. The FM signal was recorded. After the FM signal was recorded, the emulsion surface was subjected to a uniform exposure of 1000 cms for each processing by the methods described below, and then again stored in the original plastic film cartridge.

This film was loaded into the camera described in JP-A-5-150577, and after photographing, the processing temperature, the conveying speed, the total processing time and the standardization were standardized in the automatic developing machine for color reversal film with the reversal exposure device of FIG. Development processing was performed while changing the total processing time as shown in Table 7 below. Note that C
The reversal exposure apparatus described in FIG. 1 of Japanese Utility Model Laid-Open No. 63-148945 is mounted on the D processing rack. The evaluation items are the same as in Example 1, and are the magnetic reading error rate, photographic property, and transport stability.

[Table 7]

From the results shown in Table 7, as in the case of the first embodiment, the most convenient region of the transport speed S is calculated to be 0.40 m / min ≧ S ≧ 0.2 m / min. The average gradation (γ) of color reversal is about 1.8, and when projected as being softer than this, the projected image has no sharpness,
If it is harder than that, it will be an unusable image when it is color printed as an original or printed on reverse color paper, and it cannot be used. Therefore, similar to the color negative, if the required processing speed when γ is set to 1 is 0.72 m / min ≧ S ≧ 0.36 m / min. Therefore, by setting this range, it is possible to satisfy all of the magnetic characteristics, the photographic characteristics, the transportability, the shortening of the processing time, and the applicability to a small device.

From the above Examples 1 and 2, the standardized transport speed (S) required to obtain the effect of the present invention is 0.84.
m / min ≧ S ≧ 0.16 m / min, preferably 0.7
2 m / min ≧ S · γ ≧ 0.36 m / min. As a result, by standardizing as described above, the chemical characteristics of the two kinds of sensitive materials of different kinds are converted to the processing speed related to the specifications of the processing machine.
