Description

[Detailed description of the invention]

0001

[Industrial Application Field] A silver halide photographic light-sensitive material (hereinafter referred to as "photosensitive material", "photographic film") is wound around a spool by rotating a spool rotatably provided inside the main body of the cartridge in the film feeding direction. In a cartridge system for silver halide photographic light-sensitive materials containing a built-in film (abbreviated as "film" or "sensitive material"), the curling that occurs when stored in the cartridge after development processing deteriorates the flatness when reprinting. . The present invention relates to a photographic film that has improved flatness within a printer due to curling. The photographic film also relates to a sensitive material having a magnetic recording layer and having excellent transportability and magnetic recording properties.

0002

[Prior Art] In a cartridge for photographic film in which photographic film is wound and stored in a roll on a spool, for example, a 135 size film in a cartridge according to the widely popular ISO standard 1007-1979, the leading edge of the film is placed inside the cartridge body. If it is retracted, even if the spool is rotated in the film feed direction,
The film simply unwinds, and the leading edge of the film cannot be sent out from the film delivery port. For this reason, photographic film cartridges are commercially available with the leading edge of the film pulled out from the leading edge of the cartridge. The leading edge of the film must be set at a predetermined position, such as above the winding shaft of the camera, which is very troublesome for beginners, women, etc. who are unaccustomed to film loading, and there are many mistakes in loading. Therefore, a camera system that does not require such operations has been desired. Such a camera system can be realized by allowing photographic film to be fed out from inside the cartridge. In other words, if photographic film can be fed out from inside the cartridge, the leading edge of the film can be aligned with the film feeding mechanism, so there is no need to load the film edge into the film feeding mechanism as in the past, and there is no chance of loading errors. It never happens.

Furthermore, with conventional photosensitive materials, it is almost impossible to input various information at the time of photography (for example, date of photography, weather, enlargement ratio, number of prints, etc.); could only be entered. Furthermore, it is completely impossible to input information to the photosensitive material itself during printing, which is a major obstacle to achieving high speed and cost reduction. Inputting various types of information into the photosensitive material is a very important means for improving the operability and simplifying the camera in the future. As a means for inputting information, magnetic recording methods are important because they allow arbitrary input and output and are inexpensive, and have been studied in the past. For example, by appropriately selecting the amount and size of the magnetic particles contained in the magnetic recording layer, the magnetic recording layer can be made transparent so that it has the necessary transparency for the sensitive material at the time of photographing, and also does not adversely affect the granularity. Providing a support on the back side of a photosensitive material is disclosed in US Pat. No. 3,782.
No. 947, No. 4279945, No. 4302523, etc. In addition, the signal input method to this magnetic recording layer is disclosed in World Publication Nos. 90-4205 and 90-04212.
It is disclosed in the issue.

[0004] By applying these magnetic recording layers and input/output methods, it is now possible to incorporate various types of information into the photosensitive material, which was difficult to do in the past. It is now possible to input and output information such as shooting conditions, number of reprints, areas to be zoomed in, development of messages, printing conditions, etc. to the magnetic layer of the photosensitive material. Furthermore, it has the potential to be applied as a signal input/output means for directly outputting images from the photosensitive material to television/video images. When dealing with photosensitive materials that have a magnetic recording layer and can record information, it is better to return them in roll form than to cut them into pieces several frames at a time after processing and return them to the user, as was the case in the past. , when reprinting,
Printers are convenient for reading and writing information. Additionally, rolls of film are easier for users to handle than if they were to output directly to a television/video from these films. At this time, as mentioned above, the spool rotatably provided inside the cassette main body is rotated in the film feeding direction to feed out the silver halide photographic material wound around the spool from the tip. When loading the film into a printer, the leading edge of the film can be automatically aligned with the film feeding mechanism, so there is no need to manually set the film into the feeding mechanism.
Labor saving becomes possible. Therefore, when using such a system, it is necessary to roll up the developed film into a cartridge and return it to the user. At this time, it is more compact and convenient for storage if the diameter is as small as possible. However, the smaller the winding diameter, the more noticeable the curling becomes. It is clear that this increase in curling reduces the transportability within the printer when reprinting, causing the film to not pass through or being easily scratched, as well as significantly reducing flatness and making it more likely to be out of focus. It became. It has also become clear that input/output errors are more likely to occur during magnetic recording.

[0005]

SUMMARY OF THE INVENTION Accordingly, the first object of the present invention is to provide a new cartridge system in which photographic film is fed and rotated from a cartridge main body, in which photographic film is stored in the cartridge for a long time after processing. The aim is to improve the curl. A second object is to provide a photographic film that is free from the reduction in flatness within a printer that occurs when reprinting is performed using this film. A third object is to provide a photographic film having a magnetic recording layer with improved input/output errors.

[0006]

[Means for Solving the Problems] These problems were solved by rotating the spool rotatably provided inside the cartridge main body in the film feeding direction, so that the tip of the silver halide photographic light-sensitive material wound around the spool could be rotated. In a cartridge system for silver halide photographic light-sensitive materials that is fed out from a film outlet of a cartridge main body, the silver halide photographic material is rolled up into the cartridge with the silver halide photographic light-sensitive layer side rolled outward. achieved.

First, the film cartridge used in the present invention will be described. The cartridge used in the present invention is mainly composed of synthetic plastic.

Particularly preferred plastic materials for the present invention are polystyrene, polyethylene, polypropylene, and the like. Furthermore, the cartridge of the present invention may contain various antistatic agents. Antistatic agents are not particularly limited, but include carbon black, metal oxide particles, nonions, anions,
Cationic and betaine surfactants or polymers can be preferably used. As these anti-static cartridges, Japanese Patent Application Laid-open Nos. 1-312537 and 1-31
No. 2538. Especially 25℃, 25%R
The resistance at H is preferably 1012Ω or less.

[0009] It is desirable that the size of the cartridge be as large as possible in order to prevent the film stored inside from curling up. However, from the viewpoint of storage space, it cannot be made very large. It is preferable that the inner diameter of the cartridge is 50 mm or less. Along with this, the spool inside the cartridge cannot be large, and the outer diameter is 30 m.
It is preferable to keep it below m. The weight of the plastic used for the cartridge and cartridge case is 1 g or more and 25 g or less, preferably 5 g or more and 15 g or less. The ratio of the internal volume of the cartridge case to the cartridge and the plastic used for the cartridge case is 4 to 0.7, preferably 3 to 1. Preferred 135 in the present invention

g or less. The cartridge of the present invention is not particularly limited in its form. Specific examples of these cartridges are shown in FIG. 1, internal structures are shown in FIGS. 2 to 4, and magnetic recording tracks to be described later are shown in FIG. Further, a cross-sectional view of this film is shown in FIG. Furthermore, the cartridge used in the present invention, which feeds out the film by rotating the spool, will be described. Patent application No. 1-21862 is an example of the patrone.
An example of this is the cartridge described in the issue.

A cartridge (FIGS. 7 and 8) used in the present invention is shown. The photographic film cartridge 120 is attached to a spool 101, one end of which is locked to the spool 101, and the spool 1
It consists of a photographic film 102 wound into a roll 01 and a cartridge main body 103. The spool 101 is rotatably attached to the inside of the cassette main body 103 around an axis, and can be rotated from the outside of the cassette main body 103. The cartridge main body 103 is provided with a photographic film drawer opening 104 for pulling out the photographic film 102, and the inner surface of the photographic film pullout opening 104 is designed to prevent scratches caused by contact between the cartridge and the photographic film. A scratch prevention member 104a is attached. In this photographic film cartridge 120, a pair of ribs 108 extending in the circumferential direction along the inner surface of the cartridge body 103 and having a width of about 15 to 20% of the film width are provided at both ends of the film 102 in the width direction. ing. The rib 108 opens in the direction of the film outlet 104 so that the photographic film 102 can be pulled out from the film outlet 104. Further, the leading end 106 of the film 102 is connected to the photographic film drawer opening 1.
It is arranged in line with the tip 107 of 04.

The ribs 108 come into contact with the outermost surface of the film 102 and press the rolled film 102 from the outermost surface to maintain the film 102 tightly wound around the spool 101. The outer diameter of the spool 101 is determined as follows. As described above, it is difficult to tightly wind the film 102 around the spool 101 while keeping the innermost peripheral surface 102a of the film in contact with the outer periphery of the spool 101. Therefore, the formation of a gap between the innermost peripheral surface of the film 102a and the spool 101 cannot be avoided. As described above, if the distance h between the innermost circumferential surface of the film 102a and the spool 101 is too large, a reversal phenomenon of the film 102 as shown in FIG. 9 will occur. Therefore, the outer diameter of the spool 101 is such that when a gap is created between the film innermost circumferential surface 102a and the spool 101, the distance h between the two is 2.
Set it so that it is less than mm. That is, the outer diameter of the spool is a, the inner diameter of the cartridge body is b, the thickness of the rib is t,
If the thickness of the film is c, and the number of rolls that changes depending on the film length is d, then

Since b/2=a/2+h+c·d+t, a/2=b/2−t−h−c·d. Since the interval h is h=b/2-a/2-c・dt, the outer diameter a of the spool when h≦2mm
is b/2-tc·d-2≦a/2. The interval h is 2
mm or less, the spool rotation torque can be reduced to 0.
If it is set to 8 kgf·cm or less, the reversal phenomenon of the photographic film 2 can be prevented. The ribs 108 do not need to be provided along the entire circumferential direction along the inner surface of the cartridge main body 103, but may be provided only on a part of the circumferential direction of the inner surface of the cartridge main body 103. Further, in addition to being provided only at both ends of the film 102 in the width direction as in this embodiment, it may be provided over the entire width direction of the film 102.

The material of the ribs 108 is selected from a material that does not easily damage the film 102, such as plastic.
However, it is not perfect). In this case, a material having a certain degree of elasticity, such as urethane, may be selected. If the thickness of the rib 108 is determined so that the rib 108 made of urethane will shrink when the film 102 is tightly wound around the spool 101 and loaded into the cartridge main body 103, the elastic force of the contracted rib 108 will cause the film 102 to shrink. Since the outer periphery of the roll is pressed, even if the outer diameter of the roll of film 102 is reduced by pulling out a considerable length of the film 102, the tightly wound state of the film 102 can be maintained.

[0014] Any method may be used to prevent damage to the film outlet. A felt-like scratch-preventing member called "Telemp" may be provided, or a soft member such as a sponge may be provided to prevent scratches. Also,
The leading end 106 of the film 102 does not necessarily have to be arranged in line with the leading end 107 of the film outlet 104 and may be housed inside the cartridge main body 103, but it is preferable that the leading edge 106 of the film 102 be housed within the film outlet 104. Furthermore, the cartridge described in Japanese Patent Application No. 1-172594 may also be mentioned. These systems feed the film by rotating the spool while deforming the spool flange and pressing the outermost end surface of the film roll. In FIG. 10 showing the disassembled state of this photographic film cartridge, the photographic film cartridge 201 consists of a spool 206 wound with photographic film 205 in a roll shape, and a cartridge main body 2 that stores the spool 206.

The spool 206 is integrally molded from plastic and includes a thin flange 206a that is flexible and a thick flange 206b that is not flexible. The photographic film 205 is
Its terminal end is fixed to the spool 206 between the flanges 206a and 206b, and each end face is fixed to the spool 206 between the flanges 206a and 206b.
, 206b, and is wound into a roll around the spool 206 so as to run along the inside of the cartridge 206, and is completely wound into the cartridge main body 207 up to the tip. The patrone main body 20
7 is provided with a film entrance/exit 212 to which a light-shielding telescope 211 is joined. A bearing opening 208a that rotatably supports the end 206c (see FIG. 11) of the spool 206 is provided in the center of the side plate 208, and a protrusion that presses a part of the flange 206a is provided on the inner wall surface. 208b is provided. A bearing opening 209a that rotatably supports the end 206d of the spool 206 is provided in the center of the side plate 209, and near the bearing opening 209a,
A protrusion 209b (see FIG. 11) is provided to reduce friction between the inner wall surface of the side plate 209 and the flange 206b.

In FIG. 9 showing a longitudinal section of the photographic film cartridge 201, the inner dimensions of the protrusion 208b and the protrusion 209b are set to be smaller than the outer dimensions of the flanges 206a and 206b, and the protrusion 208b is The flange 206a is pressed and deformed. by this,
The outer edge of the photographic film 205 is more strongly held between the films 206a and 206b than the inner edge. Therefore, if the spool 206 is rotated in the direction of arrow A shown in FIG.
Due to the frictional engagement with the end face of the film 205, the leading end 205a of the photographic film 205 is fed out of the cartridge main body 207 through the film opening 212. Also in the above configuration, the inner dimensions of the protrusion 208b and the protrusion 209b can be made larger than the outer dimensions of the flanges 206a, 206b. In that case, by pushing the spool 206 in the direction from the flange 206b to the flange 206a with a camera part, the inner dimensions of the flanges 206a, 206b become smaller than the photographic film 205, and the end face of the photographic film 205 can be pressed. film 2

It can be sent outside of 07.

[0017] Furthermore, US Pat. No. 4,834,306 and No. 484
The cartridges described in No. 6418 and No. 4832,275 are preferably used (FIGS. 12, 13, 14). For example, as shown in FIG. 12, a photographic film 76 tightly wound around a spool 75 is held tightly wound around the spool 75 by a pair of rings 77a and 77b at both ends thereof. . Inside the cartridge body 78 are grooves 79a and 79b into which rings 77a and 77b fit.
is formed so as to form an inclined angle with respect to the axial direction of the cartridge body 78. For this reason, FIGS. 13 and 14
As shown in FIG. 1, the rings 77a and 77b abut the outer periphery of the roll of photographic film 76 at an angle inclined with respect to the axis of the spool 75 inside the cartridge body 78, thereby preventing the photographic film 76 from loosening. ring 77a,
77b slides in the grooves 79a and 79b, and
, 79b. The photographic film 76 is kept tightly wound in a roll on the spool 75 by the rings 77a and 77b, so when the spool 75 is rotated in the opposite direction to the film winding direction, the photographic film 76 is pulled out of the photographic film drawer. (not shown).

Next, the method of winding the film into the cartridge according to the present invention will be explained. Conventionally, when winding a film into a cartridge, the photosensitive layer was wound inwards. In conventional cartridge systems, when the film is unwound within the cartridge, the outer surface of the film comes into contact with the cartridge, easily causing scratches.In order to protect the photosensitive layer, the photosensitive layer is rolled inward. I'm here. Another advantage is that the camera can be designed compactly if the photosensitive layer is wound inside. However, in the system of the present invention, as explained earlier, the tape is wound tightly into the cartridge so that there is no looseness, so there is no chance of it coming into contact with the cartridge and causing damage.
The photosensitive layer may be wound inwardly or outwardly. Furthermore, in the present invention, since the developed film is simply stored in the cartridge,
There is no need to consider handling in the camera, and from this point of view, the photosensitive layer may be wound inwardly or outwardly.

Therefore, in the present invention, by winding the photosensitive layer in the opposite manner to the conventional method, that is, by winding the photosensitive layer outward, the shrinkage force of the gelatin layer, which occupies the majority of the photosensitive layer, is utilized to facilitate storage. We were able to reduce the curling that occurred inside. This mechanism will be explained below. Generally, most of the photosensitive layer of a silver halide photographic light-sensitive material consists of gelatin.
This gelatin is highly hygroscopic, absorbing moisture from the air and expanding. On the other hand, the gelatin that has absorbed enough moisture is
When brought to a low humidity environment, it releases the absorbed moisture into the air and contracts. This change is reversible, and contraction and expansion are repeated as the relative humidity changes. Stress is generated at this time, but the stress during expansion is much smaller than that during contraction. This is because the water taken in during expansion acts as a plasticizer and reduces the elastic modulus of gelatin. Therefore, when trying to use the expansion and contraction stress of gelatin to recover curl, it is more advantageous to use the contraction stress. In order for this shrinkage stress to appear significantly, the water content in the gelatin layer needs to be 14% by weight or less, more preferably 12 parts by weight or less, based on the total amount of gelatin. The moisture content of these is 2
In the case of 5° C., this can be achieved by setting the relative humidity to 40% and 30%, respectively. In order to use this shrinkage force to reduce curling, it is necessary to roll the photosensitive layer outward. This is because the inner and outer peripheries of a film with curls are longer and more stretched, and the shrinkage force of gelatin suppresses this elongation and restores the curls. be.

[0020] In fact, in order to perform curl recovery using such changes in humidity, it is most desirable to reduce the humidity in the entire room in which the printer is installed. It is best to leave the user's film in this room to adjust the humidity for at least 30 minutes, dry it, and then pass it through the printer. Also, without having to control the humidity of the entire room on a large scale like this, you can prepare a desiccator that keeps the humidity low, dry it in it for 30 minutes or more, take it out of the desiccator, and immediately pass it through the printer. In this case, it is necessary to process within 20 minutes. If it is left for a longer period of time, it will absorb moisture again to its original state, and the effectiveness of this cleaning will be significantly reduced. However, most of the normal print processing is completed within this time, so this is not a particularly big problem.

Next, the silver halide photographic film used in the present invention will be explained. First, we will discuss the supports used in photographic films. Generally, triacetyl cellulose (hereinafter abbreviated as TAC) and polyethylene terephthalate (hereinafter abbreviated as PET) are generally widely used as the support, but are not particularly limited to these. As is clear from the above explanation, curl recovery using the contraction of the gelatin layer of the present invention can provide this effect to any support. Next, the silver halide photographic film used in the present invention will be explained. First, the support used in photographic film will be described. Materials for the support of the present invention include, for example, cellulose ester (especially cellulose triacetate, cellulose diacetate, cellulose propionate, cellulose acetate propionate, cellulose butyrate, cellulose acetate butyrate), polyamide, polycarbonate, polystyrene, Examples include semi-synthetic or synthetic polymers such as polysulfone, polyethersulfone, polyarylate, polyphenylene oxide, and derivatives thereof, which may be blended as necessary, but particularly polyethylene terephthalate (hereinafter abbreviated as PET), cellulose, etc. Preferred are triacetate (hereinafter abbreviated as TAC), cellulose acetate butyrate, polycarbonate, and derivatives thereof. The molecular weight of these polymers can be 10,000 or more, but those having a molecular weight of 20,000 to 800,000 are usually used. Plasticizers are sometimes added to the support for the purpose of imparting flexibility, and in particular, for cellulose esters, triphenyl phosphate, biphenyl diphenyl phosphate,
Plasticizers such as dimethyl ethyl phosphate are used. In addition, in the support, the base color is neutralized,
It may also contain dyes for purposes such as preventing light piping and halation. These polymers may be dissolved in a solvent, made into a dope, and cast, or may be melted and cast. For example, in the case of cellulose acetate, a mixed solvent of methylene chloride and methanol or, if necessary, a solvent to which butanol or the like is added (methylene chloride to methanol ratio is 97:
3 to 80:20) at a concentration of 8 to 27%, and the solution is cast to form a film. Further, PET and derivatives thereof are formed by melt film formation. Polycarbonates and their derivatives may be melt-cast or dissolved in methylene chloride and cast.

Next, the acid- or alkali-decomposable binder or biodegradable binder used in the magnetic layer will be described. First, as an acid or alkali decomposable binder,
Those whose solubility rapidly increases and are liberated from the support when treated for a long time (more than 1 hour) under acidic or alkaline conditions (generally in aqueous solutions or water-miscible organic solvents), or chemical substances under acidic or alkaline conditions. It is not particularly limited as long as it can be decomposed and released from the support. Preferred among these binders are cellulose derivatives (monoacetylcellulose, diacetylcellulose, propionylcellulose, hydroxyethylcellulose, methylcellulose, etc.), poly(meth)acrylic esters (for example, hydroxyalkyl or allyl groups as ester residues). poly(meth)acrylamide (eg, poly(N,N-dihydroxyethylacrylamide)).

These are biodegradable plastics - Overseas trend survey report - (Published by the Bioindustry Association, June 1989)
is described in detail. When removing the magnetic layer comprising the acid/alkali or biodegradable binder of the present invention or the binder layer forming one layer on the support side from the photographic material and recovering the support, the solubility and decomposition of the binder In order to promote the properties, it is preferable to cut the photographic material into fine pieces in advance, and it is also preferable to appropriately heat, stir or blow air into the processing bath for decomposition. At this time, when processing photographic materials containing acids, alkalis, or biodegradable binders, a processing solution is generally used, but the solvent used is not particularly limited, and examples include water, alcohol (methanol, ethanol, Propanol, etc.), ketones (acetone, methyl ethyl ketone, acetophenone, etc.) are preferable, and mixed solvents thereof may also be used.

[0033] Preferably, the acid/alkalinity-providing compound used in the present invention is hydrochloric acid, sulfuric acid, nitric acid,
Examples include acidic compounds such as phosphoric acid and acetic acid, and alkaline compounds such as sodium hydroxide, potassium hydroxide, lithium hydroxide, calcium hydroxide, and ammonia, among which hydrochloric acid, sulfuric acid, sodium hydroxide, and potassium hydroxide is preferred. Furthermore, a method for decomposing a photosensitive material using a biodegradable binder will be described. In the present invention, the recovered photosensitive material is first cut into small pieces, and if there is a gelatin emulsion, it is treated with a gelatin-degrading enzyme (for example, amylase) to remove the gelatin emulsion layer, and then activated sludge is used to remove the magnetic recording layer. It is preferable to decompose it inside. The activated sludge used at this time is not particularly limited, but for example, standard activated sludge from the Chemical Safety Center (CBC) of the Japan Chemical Inspection Association can be used.

These are made by blowing air and lowering the temperature to 20
The decomposition rate can be further accelerated by maintaining the temperature at ~35°C. The longer the time required to decompose the biodegradable polymer of the present invention by the above method, the better; however, in the present invention, in consideration of recovery efficiency, it is from half a day to 20 days, more preferably from 1 day to 7 days. A cross-linking agent may be added to the magnetic layer made of the acid/alkali or biodegradable binder of the present invention or the constituent layer on the support side of the magnetic layer, for example, epoxy-based, isocyanate-based, or silane coupling-based cross-linking agent. agents can be used. The thickness of the magnetic recording layer is 0.1 μ to 10 μ, preferably 0.2 to 5 μ, more preferably 0.5 μ to 3 μ. The magnetic recording layer of the present invention is
It is preferable to provide it on the back side of the photosensitive material. The magnetic recording layer is
It can be provided on the back surface of the transparent support by coating or printing on the entire surface or in the form of stripes. It is also preferable to create a transparent support having a magnetic recording layer by co-casting or co-extruding a polymer in which magnetized particles are dispersed and a polymer for creating a transparent support in a stripe shape. In this case, 2
It is also preferred that the compositions of the different polymers be substantially the same. Air doctor coating, blade coating, air knife coating, squeeze coating, impregnation coating, reverse roll coating, transfer roll coating, gravure coating, kiss coating, cast coating, spray coating, etc. are used to apply this magnetic recording layer in stripes. However, other methods are also possible, and specific explanations of these methods are described in detail in "Coating Engineering" published by Asakura Shoten, pages 253 to 277 (published on March 20, 1972).

By such a method, the magnetic layer coated on the support is immediately subjected to a treatment to orient the magnetic powder in the layer while drying, if necessary, and then the formed magnetic layer is dried. The transport speed of the support at this time is usually 10 m.
/min to 500m/min, and there may be one or two or more at one end. In that case, one may have a large amount of magnetic material and be opaque, and the other may have a small amount of magnetic material. Further, striped magnetic recording layers may be provided at both ends of the film, and one side may be opaque and the other transparent. By forming a transparent stripe-shaped magnetic recording layer, optical recording can be provided thereon, and the advantage can be provided that a magnetic recording layer can be formed without damaging the conventional optical system. Moreover, there is no particular problem even if the stripes are transparent. Furthermore, when the striped magnetic recording layer of the present invention is applied, since the non-stripe areas are generally depressed compared to the striped areas, there are various problems such as poor adhesion when the sensitive material is stored for a long time under high temperature and high humidity. This causes problems such as deterioration of the image quality, pressure fogging around the stripes in terms of photographic properties, and powder falling off at the edges of the stripes. One way to solve this problem is to make the striped magnetic recording layer portion and the non-stripe portion on the same plane. That is, a non-magnetic recording layer having the same thickness as the stripe layer may be provided in the non-stripe portion other than the stripe-shaped magnetic recording layer.

Any method may be used to provide the non-magnetic layer portion. For example, this can be achieved by coating a magnetic recording layer on a sensitive material in stripes by coating, printing, vapor deposition, transfer, etc., and then coating other non-magnetic recording layers separately from the magnetic recording layer. . Alternatively, the magnetic recording layer and the non-magnetic recording layer may be applied at the same time; for example, the coating liquid for the magnetic recording layer and the coating liquid for the non-magnetic recording layer may be alternately extruded using a Giesser divided into the same plane. Alternatively, if a gravure coater is used, each coating liquid may be applied alternately in the same manner. Furthermore, instead of extruding the coating liquid onto the same plane, stripes may be formed by extruding and dividing the coating liquid onto different coating surfaces. By doing this, the striped magnetic recording layer and the non-magnetic recording layer can be made to have the same thickness. can do. Furthermore, a striped magnetic recording layer can be applied when producing the support. That is, when the slits of one or two manifolds of a co-casting die having a plurality of manifolds have a comb-like cross-sectional shape, and when two of the slits have a comb-like shape, the openings of the comb-like slits are aligned in the width direction. This is achieved by a film forming method for a photographic support using a die that enables step-free stripe co-casting by merging them in an alternately interpolated manner.

Furthermore, in a film forming method in which a plurality of liquids are co-extruded using a co-casting die having a plurality of manifolds, two of the manifolds adjacent to each other have slits having a comb-like cross-sectional shape. Moreover, by merging the openings of the comb-like slits from the two manifolds so as to interpolate them alternately in the width direction, a support having a striped magnetic recording layer having a uniform thickness can be produced. As the binder for forming the non-magnetic recording layer portion having the same thickness as the striped magnetic recording layer used in the present invention, the binder used for the striped magnetic recording layer described above can be used as is. Preferably, the binder has the same magnetic recording portion and non-magnetic recording portion. Formation of a striped recording layer by melt extrusion can also be achieved by the same method as above. As a method for applying a magnetic material layer to the entire surface of the support, it can also be obtained by forming a film of a binder containing a magnetic material on the support as described in JP-A-2-29920. At this time, the binder containing the magnetic material may be a polymer having the same composition as the support. Furthermore, Japanese Patent Publication No. 57-25954
A film containing a magnetic material may be laminated and adhered to a support as described in the above. The magnetic recording layer may also have functions such as improving lubricity, controlling curl, preventing static electricity, and preventing adhesion, or another functional layer may be provided to impart these functions. If necessary, a protective layer may be provided adjacent to the magnetic recording layer to improve scratch resistance.

[0038] The back surface of the transparent support having the magnetic recording layer is calendered to improve smoothness and to reduce the S of the magnetic signal.
/N ratio can be improved. In this case, it is preferable to apply a photosensitive layer on the transparent support after calendering. In the present invention, a matting agent may be included in the sensitive material to prevent adhesion. At this time, the matting agent used is not particularly limited in its composition, and may be an inorganic or organic substance, or a mixture of two or more types. It may be applied to the back side or the emulsion side, and it is more preferable to apply it to both sides. Particularly preferred matting agents for the back side are listed below. The particles used in the present invention are particles that remain in the photosensitive material even after development processing, and are characterized by being insoluble in the processing solution, and those that are extremely hydrophilic or do not contain large amounts of groups that dissolve in alkaline or acidic conditions. is desirable. Examples of the inorganic and organic compounds of the matting agent of the present invention include fine powders of inorganic substances such as barium sulfate, manganese colloid, titanium dioxide, barium strontium sulfate, and silicon dioxide. Examples include silicon dioxide such as synthetic silica obtained by chemical reaction, and titanium dioxide (rutile type and anatase type) produced by titanium slag and sulfuric acid. In addition, the particle size is relatively large, for example, 20 μm.
It can also be obtained by pulverizing the above inorganic substances and then classifying them (vibration filtration, air classification, etc.).

[0039] Also included are pulverized and classified products of organic polymer compounds such as polytetrafluoroethylene, cellulose acetate, polystyrene, polymethyl methacrylate, polypropyl methacrylate, polymethyl acrylate, polyethylene carbonate, and starch. Alternatively, a polymer compound synthesized by a suspension polymerization method, a polymer compound made into a spherical shape by a spray drying method or a dispersion method, or an inorganic compound can be used. Further, a polymer compound that is a polymer of one or more types of various monomer compounds that can be polymerized may be made into particles by various means. Among these monomer compounds, acrylic esters, methacrylic esters, vinyl esters, styrenes, and olefins are preferably used. Also,

After 1.0 l, the performance of the obtained sample was evaluated.

1-6) Storing the developed film in the cartridge and core setting The film was wound up again into the cartridge that had been placed before the development process. Regarding the size of the cartridge, the outer diameter of the spool was 7.5 mm, and the inner diameter of the cartridge body was 20 mm. At this time, the photosensitive layer was rolled outward and stored in the cartridge. Furthermore, as a comparative example of the present invention, a product in which the photosensitive layer was wound inside and housed was also made. These samples were aged for 18 hours in a 50°C air temperature chamber, curled, and then heated at 25°C and 60% RH.
The sample that was conditioned for 3 hours was used as a sample for evaluation.

1-7) Performance evaluation A sample with the photosensitive layer wound outward and a sample with the photosensitive layer wound inside were conditioned for 3 hours at 25°C, 20% RH and 25°C, 60% RH, respectively, and then exposed to each atmosphere. The following evaluations were made: (a) Evaluation of winding curl After the sample film was taken out from the cartridge under a predetermined environment, the winding diameter of the innermost circumference was measured 5 minutes later using a caliper. The larger the number, the smaller the curl. (b) Evaluation of flatness and transportability in the printer The test pattern of the sample film photographed was placed in the printer (Fuji Photo Film Co., Ltd. printer FAP-7000) 10 times starting from the innermost side with the strongest curl. The passability at that time was evaluated. We also printed a test pattern of the sample film onto photographic paper, and evaluated the flatness of the sample film in the printer based on the amount of defocus. c) Evaluation of output errors in magnetic recording Using the signal input method disclosed in the above-mentioned World Publication No. 90-04205, a magnetic head is used to output the sensitive material 100 times, which is magnetically input from the back side after development processing. Indicates the number of errors. d) Evaluation of the feeding torque of photographic film from the cartridge The spool in the cartridge was rotated, and the torque when the film came out from the film drawer opening was measured. The larger the value, the worse the delivery performance. e) Measurement of moisture in the gelatin layer A sample that has been conditioned in the specified environment is first transported for 40 m.
A sample is taken in a rectangle of m x 9 mm, and the water content is measured using the Karl Fischer method. (The water content at this time is x%.) Furthermore, after sampling the same size again in the immediate vicinity, quickly scraping off all the photosensitive layer with a razor, and immediately measuring by the Karl Fischer method. (The moisture content at this time is y%.) x-y (%)
was taken as the water content in the gelatin layer.

1-8) Evaluation results The results are shown in Table 1.

[0075]

[Table 1]

As is clear from Table 1, as in the present invention,
In the samples in which the photosensitive layer was wound outwardly under low humidity (20% RH), the curling curls were significantly recovered compared to other Comparative Examples 11 to 13. This is because gelatin in the photosensitive layer contracts when placed under low humidity, working to restore curl. On the other hand, comparative example-1
If the photosensitive layer is rolled inward and placed under low humidity as in 2, on the contrary, the curl will increase due to the shrinkage force of gelatin. In addition, under high humidity (60% RH), gelatin in the photosensitive layer tries to stretch, but the elastic modulus at this time becomes extremely small due to the plasticizing effect of water, and almost no curling occurs. Does not contribute to recovery. Therefore, whether the photosensitive layer is wound internally or externally, there is almost no difference as in Comparative Examples -11 and -13. When the curl is improved as in the present invention, jamming during transportation within the printer is significantly improved. It also reduces out-of-focus during printing. This is because the reduction in flatness of the negative film inside the printer, which occurs due to curling, has been improved. In addition, poor contact with the magnetic head is improved due to reduced winding curl,
Input/output errors were also reduced. In addition, there is less curling and the film base can easily come out straight from inside the cartridge.
Delivery torque has also been improved. As described above, by rolling the photosensitive layer outward and handling it under low humidity as in the present invention, problems that could not be solved by conventional techniques could be solved.

Example 2 2-1) Preparation of Support A support having a thin layer of PET containing a magnetic material on one side of a PET support was formed by coextrusion using the following method. (Raw material A) Polyethylene terephthalate (Raw material B) Polyethylene terephthalate

The thickness was adjusted to 10 μm and extruded at 280°C. Next, this was biaxially stretched 3.5 times in the longitudinal direction at 90°C and 3.7 times in the transverse direction at 95°C, and then fixed at 200°C for 5 seconds. The total thickness of the support thus obtained was 98 μm, of which the thickness of the magnetic layer was 3 μm.

2-3) Preparation of photosensitive material After corona discharge treatment is applied to the opposite side of the back layer of each film support obtained by applying the undercoat, each layer having the composition shown below is coated in a multilayer manner. Photographic film, which is a color photosensitive material, was created. (Photosensitive layer composition) Similar to Example 1, a photosensitive layer was prepared in exactly the same manner as the photosensitive layer described in Example 1 of JP-A-2-93641. The layer structure of the photographic film thus produced is shown in FIG. 2-4) Sample processing The same procedure as in Example 1 was carried out. 2-5) Development of photographic film The same procedure as in Example 1 was carried out. 2-6) Storing the developed film in the cartridge and core setting The film was rolled up again into the cartridge that had been placed before the development process. The photosensitive layer was wound outwardly into a cartridge whose spool had an outer diameter of 11 mm and an inner diameter of 22 mm. At the same time, as a comparative example, the photosensitive layer was wound outward. In addition, as a comparative example, the outer diameter is 35 mm and the inner diameter is 60 mm, which is larger than the range of the present invention.
The photosensitive layer was also rolled into a cartridge of mm by the inner and outer windings. These samples were aged for 18 hours in an air temperature chamber at 60°C, curled, and then heated at 25°C and 60% RH.
After conditioning the humidity for 3 hours, it was used as a sample for evaluation. 2-7) Performance Evaluation The items and contents of performance evaluation are exactly the same as in Example 1.

2-8) Evaluation results The results are shown in Table 2.

[0084]

[Table 2]

As is clear from the comparison between the present invention and Comparative Examples 21 to 23 in Table 2, similar effects were confirmed in the PET base as in Example 1. Comparative examples 24 to 27 in Table 2 show comparative examples in which a cartridge larger than the size specified in the present invention was used. The performance obtained with the present invention is comparable to these comparative examples.
This was achieved with a small cartridge of about 1/3. Incidentally, in the case of large diameter cartridges such as Comparative Examples 24 to 27, since the winding curl was small from the beginning, no great effect was observed even when the present invention was applied.

6) Storing the developed film in the cartridge and core setting The film was rolled up again into the cartridge that had been placed before the development process. As for the size of the cartridge, the outer diameter of the spool was 7.5 mm, and the inner diameter of the cartridge body was 20 mm. At this time, the photosensitive layer was rolled outward and stored in the cartridge. Furthermore, as a comparative example of the present invention, a product in which the photosensitive layer was wound inside and housed was also made. 60 of these samples
After aging in an air constant temperature bath at 18 degrees Celsius, curling was added, and the humidity was conditioned at 25 degrees Celsius and 60% RH for 3 hours, and this was used as an evaluation sample. 3-7) Performance Evaluation A sample with the photosensitive layer wound outward and a sample with the photosensitive layer wound inward were each placed in a desiccator at 25° C. and 10% RH, and 25° C. and 70% RH for 3 hours. After this, the sample was taken out from the desiccator and heated at 25°C.
It was transferred to an atmosphere of 60% RH, and 10 minutes later, evaluation as shown in Example 1 was performed. This means that during actual processing in a laboratory, if the entire room is made to have low humidity, costs will increase, but it is not a desirable working environment for humans. Therefore, the same effect of the present invention can be obtained by storing the photosensitive layer in a desiccator at low humidity to remove moisture from the photosensitive layer and then passing it through a printer. However, since the hygroscopic behavior of the photosensitive layer is reversible, if it is left in a normal humid atmosphere, it will absorb moisture again, reducing its effectiveness. Therefore, it is preferable to run the sample through the printer preferably within 30 minutes, more preferably within 20 minutes after removing it from the desiccator.

3-8) Evaluation results The results are shown in Table 3.

Effects of the Invention The present invention allows the tip of the silver halide photographic light-sensitive material wound around the spool to be transferred to the film of the cartridge body by rotating the spool rotatably provided inside the cartridge body in the film feeding direction. In a cartridge system for silver halide photographic light-sensitive materials that is fed out from a drawer opening and has a magnetic recording layer, when the photographic material is stored in the cartridge after development processing, the light-sensitive layer side By using the method of the present invention of reducing the water content of gelatin in the photosensitive layer to 14% by weight or less when storing the gelatin by rolling it outward and reprinting it, it will not stick to the cartridge during long-term storage. This reduces the amount of curling, which improves out-of-focus during printing, improves conveyance within the printer, reduces delivery torque from the cartridge, and reduces magnetic input/output errors.
