Description

  The present invention relates to a magnetic information recording medium having an image and a magnetic recording layer, and more specifically, a cash card with a face photo, an employee ID card, a student ID card, a personal ID card, a residence card, various driving licenses, and various qualifications. The present invention relates to a magnetic information recording medium containing non-contact or contact-type personal information image information such as certification, an RFID tag, an image sheet for personal verification used in medical practice, an image display board, a display label, etc. Is.

Conventionally, cards such as cash cards provided with an image and a magnetic recording layer are imaged by offset printing or the like on the surface of the card base (support) on which the magnetic tape is previously attached. It was produced through the process of forming. However, this card has a problem that a magnetic recording layer and an image formed by attaching a magnetic tape to the surface of a support are formed, and the magnetic recording layer and the image are easily worn or damaged.

On the other hand, since an image formed on a card can be protected, a method of producing a card using a transfer member has also been proposed (see Patent Document 1).
In this method, an image is once formed on the surface of the transfer body using an existing electrophotographic image forming apparatus using a transfer body having a heat-fusible image-receiving layer on the surface of the substrate, and then a plastic sheet. A card with an image formed on the interface between the image support and the image receiving layer is prepared by laminating the image on the image support, laminating by heating and pressing, and then peeling off the base portion of the transfer body. Can do.
JP 2005-227377 A

Therefore, in the card (magnetic information recording medium) obtained by forming the magnetic recording layer together with the image at the interface between the image support and the image receiving layer using the above-described method, the image and the magnetic recording layer are externally connected. Can be protected from mechanical stimulation.
However, in a magnetic information recording medium in which a magnetic recording layer is provided together with an image at the interface between an image support and an image receiving layer, in order to read and write magnetic recording information by a magnetic information reading (and / or writing) device, When the magnetic information recording medium is repeatedly passed through the groove portion for the card in which the reading (and / or writing) sensor of the apparatus is disposed, peeling at the interface may occur and the mechanical durability may be lacking.
An object of the present invention is to solve the above problems. That is, an object of the present invention is to provide a magnetic information recording medium excellent in mechanical durability.

The above object is achieved by the present invention described below. That is, the present invention
A support having at least one surface containing a thermoplastic resin, a heat-fusible layer provided on at least a surface of the support containing the thermoplastic resin, and an interface between the support and the heat-fusible layer Comprising at least a magnetic recording layer and an image disposed on
The magnetic recording layer is composed of a magnetic material layer and an adhesive layer provided on one side of the magnetic material layer,
The magnetic recording layer is disposed at an interface between the support and the heat-sealing layer so that the surface on the magnetic material layer side is in contact with the surface of the support including the thermoplastic resin. And a magnetic information recording medium.

  As described above, according to the present invention, a magnetic information recording medium having excellent mechanical durability can be provided.

  The magnetic information recording medium of the present invention includes a support having at least one surface containing a thermoplastic resin, a heat fusion layer provided on at least the surface of the support containing the thermoplastic resin, and the support. A magnetic recording layer and an image disposed at the interface between the magnetic material layer and the heat fusion layer, and the magnetic recording layer comprises a magnetic material layer and an adhesive layer (hot melt adhesive) provided on one side of the magnetic material layer. The magnetic recording layer is at the interface between the support and the heat-sealing layer so that the surface on the magnetic material layer side is in contact with the surface containing the thermoplastic resin of the support. It is arranged.

  In finding the above-mentioned present invention, the present inventors have intensively studied the cause of the occurrence of defects in the mechanical durability of a magnetic information recording medium produced using a transfer body. As a result, when the magnetic information recording medium in which peeling at the interface occurred was repeatedly passed through the groove portion of the magnetic information reading (and / or writing) device, peeling was performed mainly on the portion where the magnetic recording layer was disposed. It was found that occurred. Further, this peeling occurred at the interface portion between the magnetic recording layer and the support. From this, it is considered that the cause of peeling is that the adhesive force between the magnetic recording layer and the support is insufficient.

  On the other hand, a commercially available magnetic tape is usually used for forming the magnetic recording layer. The magnetic tape includes a magnetic recording layer portion including a magnetic material layer composed of a magnetic material and an adhesive layer composed of a heat-meltable adhesive that exhibits adhesiveness when melted by heating. It is composed of a PET (polyethylene terephthalate) film that serves as a support for holding the magnetic recording layer until the magnetic tape is used, and has a release film that is peeled off from the magnetic recording layer when used. In addition, this magnetic tape has a configuration in which one surface is constituted by a release film and the other surface is provided with an adhesive layer so that the other surface can be adhered to an object to which the magnetic tape is to be attached.

Further, when producing the magnetic information recording medium, a magnetic tape is attached to the surface of the transfer member having the base and the heat-sealing layer provided on at least one side of the base. A transfer body in which the magnetic recording layer is attached to the surface by peeling off the release film from is used. Therefore, in the magnetic information recording medium, the surface of the magnetic recording layer on which the release film is provided comes into contact with the support surface.
Therefore, when the magnetic tape used for the magnetic information recording medium where peeling occurred was investigated, the magnetic recording layer was found to be an adhesive layer and a magnetic material layer disposed on the surface opposite to the adhesive surface of the adhesive layer. It was also found that a protective layer covering the magnetic material layer was provided. This protective layer is made of a resin having a relatively high releasability provided to protect the magnetic material layer on which magnetic information is recorded after the release film is peeled from the magnetic tape.

  Therefore, the present inventors considered that peeling occurs because the surface of the magnetic recording layer on the protective layer side is in contact with the support. On the other hand, in a magnetic information recording medium manufactured using a transfer body, since the magnetic recording layer is disposed at the interface between the heat fusion layer of the transfer body and the support, the magnetic recording layer is protected by the heat fusion layer. Is done. Therefore, the protective layer as described above is unnecessary. Therefore, if a magnetic tape without such a protective layer is used, the magnetic material layer composed of an inorganic magnetic material can be in direct contact with the surface of the support, and thus the protection composed of a resin having a relatively high release property. Compared to the case where the layer is in direct contact with the support surface, the thermoplastic resin on the support surface can exhibit sufficient adhesion to the magnetic material layer by heating when the transfer body and the support are joined. It is considered a thing.

  The present inventors have found the present invention described above based on the knowledge described above. Therefore, the magnetic information recording medium of the present invention is excellent in mechanical durability because peeling at the interface between the magnetic recording layer and the support is suppressed.

  In the above description, the magnetic information recording medium of the present invention does not have a transfer body having a base and a heat fusion layer provided on at least one side of the base, or a protective layer for forming the magnetic recording layer. Although it is assumed that the magnetic tape is manufactured using a magnetic tape, the manufacturing method thereof is not particularly limited as long as the magnetic information recording medium of the present invention can be manufactured without using these members. However, it is usually produced using a magnetic tape having no transfer member and no protective layer.

  Hereinafter, on the premise that a magnetic tape having no transfer body and no protective layer is used, the method for producing a magnetic information recording medium of the present invention, members used therefor, and the like will be described in more detail.

-Manufacturing method of magnetic information recording medium-
In the present invention, (1) a support having at least one surface containing a thermoplastic resin, (2) a transfer body having at least a substrate and a heat-sealing layer provided on at least one surface of the substrate, and (3) A release film, a magnetic recording layer provided on one side thereof (the magnetic recording layer is formed of an inorganic magnetic material and is disposed in contact with the release film, and a release film of the magnetic material layer is provided. The magnetic information recording medium is manufactured using the above three main members.

-Formation of image and magnetic recording layer-
Here, when producing a magnetic information recording medium, first, an image and a magnetic recording layer are formed on the surface of the transfer body on which the heat-sealing layer is provided (hereinafter sometimes referred to as “joining surface”). To do. Note that either the image formed on the bonding surface or the magnetic recording layer may be formed first, but it is usually preferable that they are formed so as not to overlap each other.
The image formed on the joint surface is preferably a toner image formed using an electrophotographic image forming apparatus. However, the present invention is not limited to this. For example, an image that can be formed on a joint surface by a known image forming apparatus, such as an ink image formed using an ink jet image forming apparatus, is particularly suitable. It is not limited. The toner image formed on the joint surface of the transfer body may be an unfixed image. In this case, an unfixed image can be fixed by using a heat treatment in a joining step for joining a transfer body and a support, which will be described later.

Further, the magnetic tape can be attached to an arbitrary position on the joining surface of the transfer body. In the case where the magnetic tape has a belt-like shape and the magnetic recording layer is transferred to the bonding surface and then an image is formed on the bonding surface using an electrophotographic image forming apparatus, the magnetic recording layer is The longitudinal direction is within a range of 0 ° ± 45 ° with respect to the feeding direction when the transfer body is fed to the image forming apparatus, and particularly preferably 0 ° (that is, the longitudinal direction of the magnetic recording layer and the feeding direction) Is preferably transferred to the joint surface of the transfer body so that the two are consistent.
In this case, when the transfer body passes between a pair of fixing members composed of a roll of a fixing device or a belt-like member arranged in the image forming apparatus, the transfer surface is bonded to the magnetic recording layer. Air remaining at the interface is efficiently pushed out. The air remaining at the interface between the transfer sheet bonding surface and the magnetic recording layer deteriorates the appearance of the magnetic information recording medium, but if the above-described method is used, there is almost no air remaining at the interface. The resulting magnetic information recording medium does not deteriorate in appearance.
In the present invention, the magnetic recording layer is disposed at the interface between the support constituting the magnetic information recording medium and the heat fusion layer. However, in the above-described method, the magnetic recording layer is disposed on the surface of the magnetic information recording medium. It can also be used for cases where

-Overlay process-
After producing a transfer body in which an image and a magnetic recording layer are formed on the joint surface, a laminate is formed by superimposing the joint surface of the transfer body and the surface of the support containing the thermoplastic resin.
Here, if necessary, the surface of the transfer body and the surface of the support (and / or the surface of the support) are bonded together by thermal welding or an adhesive before finishing the superposition process and performing the joining process described later. It is also possible to carry out temporary holding using mechanical fixation with a staple needle or the like. As a result, it is possible to reliably prevent displacement between the transfer member and the support.

The size of the support and transfer member used for the production of the magnetic information recording medium of the present invention is not particularly limited, but a small size is preferably used.
In this case, it is preferable to carry out a superimposing step and a joining step and a peeling step described later using a holding body that holds the support. If a magnetic information recording medium can be produced by using a small-sized support and a transfer body as they are, a small-sized magnetic information recording medium is finally obtained by using a large-sized support and a transfer medium of a fixed size such as A3 size and A4 size. Compared with the case of manufacturing, the cutting process can be omitted, so that productivity can be significantly improved.

  On the other hand, when carrying out the overlaying process, joining process, and peeling process using mechanical means using a support having a small size, the size of the support is too small. Another problem is that mechanical handling becomes difficult, for example, a positional deviation occurs between the support of the laminated body and the transfer body. In this case, as a result, the position of the image formed at the interface between the heat fusion layer of the magnetic information recording medium and the support is likely to be displaced. However, the use of the holding body can suppress the occurrence of such a problem.

Here, the “small size” means a size smaller than the smallest size (postcard size) among the standard sizes of commercially available paper.
Specifically, when the shape of the support is a quadrangle, for example, the vertical and horizontal lengths are each in the range of 10 mm to 120 mm, and the vertical: horizontal aspect ratio is in the range of 1: 1 to 1:12. Means things. The vertical and horizontal lengths are more preferably in the range of 30 mm or more and 90 mm or less, and the aspect ratio between the vertical and horizontal is preferably in the range of 1: 1 to 1: 3. From the viewpoint of practicality, the size specified in JIS X-6302 is suitable. On the other hand, when the shape of the support is a shape other than a quadrangle, for example, a circle, an ellipse, a triangle, a star, etc. It means that the length is in the range of 10 mm to 120 mm and the aspect ratio of the maximum length and the length in the direction orthogonal to the maximum length direction is in the range of 1: 1 to 1:12. The maximum length is more preferably in the range of 30 mm or more and 90 mm or less, and the aspect ratio between the maximum length and the length in the direction orthogonal to the maximum length direction is more preferably in the range of 1: 1 to 1: 3. Details of the holder will be described later.

-Joining process-
The laminated body obtained through the superposition process is subjected to heat treatment, more preferably pressure treatment together with the heat treatment, so that the joined surface of the transfer body and the surface containing the thermoplastic resin of the support are joined to each other. Get.
It does not specifically limit as a joining method, All can employ | adopt conventionally well-known various lamination techniques. For example, an image, a magnetic recording layer, and a support can be obtained by inserting the laminated body through a contact portion formed so that a heating roll and a pressure roll, which are arranged so as to be pressed against each other, are pressed against each other. Ordinary laminating techniques in which these are heat-melted to some extent and heat-sealed, and hot pressing techniques can be used.

  In addition, since the magnetic material layer constituting the magnetic recording layer is thermally fused and bonded to the surface including the thermoplastic resin of the support by the heat treatment performed in the joining process, the magnetic recording layer and the support Separation at the interface is suppressed. Here, this heat treatment is performed at a temperature (in a range of about 90 ° C. or higher and 130 ° C. or lower) at which the thermoplastic resin constituting the surface including the thermoplastic resin of the support can be heat-sealed.

-Peeling process-
For the bonded body obtained through the bonding process, a peeling process is performed to peel the interface between the substrate and the heat-sealing layer of the transfer body portion constituting the bonded body.
The implementation method of a peeling process is not specifically limited, For example, you may peel manually and may implement mechanically using a peeling nail | claw etc. When a plurality of individual images are formed in the medium obtained through the peeling process, each image is cut to obtain a plurality of magnetic information recording media of a predetermined size.

Further, positioning means for aligning and superimposing the positions of the transfer body and the holding body 22 so that the image on the surface of the transfer body 20 and the magnetic recording layer face a desired position on the surface of the support body held by the holding body 22. Is provided.

The configuration of the positioning means is not particularly limited, and examples thereof include the configurations shown in FIGS. 3 and 4.

FIG. 3 is a plan view when the collating means 36 is viewed from above. 4 is a cross-sectional view of the collating means 36 (cross-sectional view between X1 and X2 in FIG. 3), in which 61, 61a, 61b, 62 are reference walls, and 63, 64 are regulation Reference numeral 70 denotes a member, and 71 denotes a connecting portion.

  The collating means 36 has four sides with respect to the conveying direction indicated by the arrows in the figure (in FIG. 2, the side on which the transfer body storage section 32 and the holding body storage section 34 are arranged with respect to the collating means 36). Square receiver 70 whose two sides are orthogonal to each other, reference wall 61 arranged along the downstream side in the conveying direction, and reference arranged along one of the two sides orthogonal to the side.

If the reference wall 61 is moved to a location indicated by 61b, the laminate P can be transported downstream in the transport direction.

  The collating means 36 may be provided with a temporary fixing device for temporarily fixing a laminated body in which the holding body 22 and the transfer body 20 are overlapped. As this temporary fixing device, for example, a device composed of a pair of protruding pieces made of metal so as to be heated by a heater or the like can be used. If this device is used, the laminate is sandwiched by a pair of heated protruding pieces. Thus, the transfer body 20 and the holding body 22 and / or the support body held by the holding body 22 are welded by heat, and the laminated body is temporarily fixed.

Next, in the joining device 14, the laminated body composed of the transfer body 20 and the holding body 22 is transferred by heating and pressurizing through a contact portion where the outer peripheral surfaces of the pair of endless belts 46 are in contact with each other. The body 20 and the support are joined to obtain a joined body (joining step).
The joined body that has passed through the contact portion is discharged to the magnetic information recording medium discharge portion 56. Subsequently, the substrate is peeled from the joined body and removed from the holding body 22 to obtain a magnetic information recording medium on which an image is formed.

-Transcript-
The transfer body used in the present invention has a substrate and a heat-sealing layer provided on at least one surface of the substrate. If necessary, one or more intermediate layers and a heat-sealing layer are formed on the surface of the substrate. May be laminated in this order. Further, the image formed on the transfer body is formed on the heat fusion layer.
Here, the image formed on the heat-sealing layer is not particularly limited as long as it is formed by a known recording method. For example, it may be an image formed by a method in which a solid or liquid image forming material is applied to the surface of the heat sealing layer. In this case, the image is typically formed by an electrophotographic method or an ink jet recording method. Images. Furthermore, when the heat-sealable layer has a function of changing color or coloring when external stimuli such as heat or light are applied, an image formed by changing the color or color of the surface of the heat-sealable layer by applying external stimuli. In this case, typically, an image formed by a photosensitive recording method, a thermal recording method, or a photosensitive thermal recording method can be given.

  Hereinafter, a preferable transfer member used in the present invention will be described in more detail on the assumption that an image provided on the surface of the transfer member is formed by electrophotography as an example.

In the transfer body used in the present invention, in order to improve the transferability of an image formed by electrophotography, the surface resistivity of the heat-sealing layer is 1.0 at 23 ° C. and 55% RH. It is preferably in the range of × 10 ^{8 to} 3.2 × 10 ¹³ Ω, and preferably in the range of 1.0 × 10 ^{9 to} 1.0 × 10 ¹¹ Ω.

If the surface resistivity is less than 1.0 × 10 ⁸ Ω, the resistance value of the transfer body used as the image receiver at high temperature and high humidity becomes too low. For this reason, the toner image may be disturbed when an unfixed image (toner image) is transferred to the surface of the transfer member in the electrophotographic apparatus. On the other hand, if the surface resistivity exceeds 3.2 × 10 ¹³ Ω, the resistance value of the transfer member used as the image receiver becomes too high, and the toner image cannot be transferred to the transfer member surface in the electrophotographic apparatus. In some cases, image defects may occur due to transfer defects.

For the same reason, when the heat fusion layer is provided only on one side of the substrate, the surface resistivity at 23 ° C. and 55% RH of the surface of the substrate on the side where the heat fusion layer is not provided is 1 The range is preferably from 0.0 × 10 ⁸ Ω to 1.0 × 10 ¹³ Ω, and more preferably from 1.0 × 10 ⁹ Ω to 1.0 × 10 ¹¹ Ω.

  The surface resistivity difference between the front and back surfaces of the transfer body at 23 ° C. and 55% RH is preferably within 4 digits, more preferably within 3 digits. If the surface resistivity difference between the front and back surfaces exceeds 4 digits, toner transfer failure is likely to occur and image deterioration may occur. The difference in surface resistivity within 4 digits means that the difference in common logarithm is within 4 when each surface resistivity is expressed in common logarithm.

  The surface resistivity is measured by a method based on the double ring electrode method in JIS K 6911, and is obtained by following the calculation formula presented at the same time. More specifically, a digital ultra-high resistance / microammeter R8340 manufactured by Advantest Co., Ltd. connected to a circular electrode (for example, “HR probe” of Hiresta IP manufactured by Mitsubishi Yuka Co., Ltd.) It calculated | required from the calculation formula prescribed | regulated to JISK6911 based on the electric current value 60 second after by the applied voltage 1000V in the environment of (degreeC) and 55% RH.

In controlling the surface resistivity of the heat-fusible layer within the range of 1.0 × 10 ⁸ Ω to 1.0 × 10 ¹³ Ω, it is preferable to include a charge control agent in the heat-fusible layer. As the charge control agent, for example, a polymer conductive agent, a surfactant, conductive metal oxide particles, or the like can be used.

The Vicat softening temperature of the heat-sealing layer is preferably in the range of 70 ° C. or higher and 130 ° C. or lower, and more preferably in the range of 80 ° C. or higher and 120 ° C. or lower. It is preferable that at least the heat sealing layer has the Vicat softening temperature.
If the Vicat softening temperature exceeds 130 ° C., the transfer body may not be sufficiently adhered and adhered to the support. In addition, if the Vicat softening temperature is less than 70 ° C., even if the adhesion / adhesion is sufficient, the heat-sealing layer may be too soft, and a defect (image flow) may occur in the image. .

Here, the Vicat softening temperature is measured from a method for evaluating the softening temperature of a thermoplastic resin. The measuring method is a method for testing the heat resistance of a molded plastic material. The method is defined in JIS K7206, ASTM D1525, and ISO306.
In the present invention, a test piece having a thickness of 2.5 mm is used, a needle-like indenter having a cross-sectional area of 1 mm ² is set on the surface, a load of 1 kg is placed on the indenter, and the temperature of the oil tank for heating the test piece is set. The oil temperature when the indenter entered 1 mm into the test piece was defined as the Vicat softening temperature.

  In order to improve the conveyance of the transfer body in the electrophotographic apparatus, the heat sealing layer may contain a filler. The volume average particle diameter of the filler is preferably 0.1 μm or more and 30 μm or less, but is preferably 1.2 times or more of the heat fusion layer thickness in consideration of the heat fusion layer thickness. If it is too large, the filler may be detached from the heat-sealing layer, and the surface of the transfer body is likely to be worn and damaged, and the haze (degree of haze) may increase.

  As the shape of the filler, spherical particles are generally used, but may be a plate shape, a needle shape, or an indefinite shape. Moreover, as a material which comprises a filler, a well-known resin material and an inorganic material can be utilized.

  Although it does not specifically limit as a base | substrate, A plastic film can be used typically. Among these, polyacetate film, cellulose triacetate film, nylon film, polyester film, polycarbonate film, polysulfone film, polystyrene film, polyphenylene sulfide film, polyphenylene ether film, cyclohexane film, which are light transmissive films that can be used as OHP films. An olefin film, a polypropylene film, a polyimide film, a cellophane, an ABS (acrylonitrile-butadiene-styrene) resin film, or the like can be preferably used. Paper (plain paper, coated paper, etc.), metal (aluminum, etc.), ceramics (alumina, etc.) can also be used.

  The surface of the substrate on which the heat-sealing layer is provided is preferably 1 μm or less, more preferably 0.1 μm or less, in terms of surface roughness (centerline average roughness Ra). When the surface roughness (centerline average roughness Ra) exceeds 1 μm, high glossiness may not be obtained.

The transfer body is provided with at least one layer including a heat-sealing layer on the same surface of the substrate, and at least one of these layers is a layer containing a curable resin. Particularly preferred. In this case, the layer containing the curable resin is a layer that can be peeled from the substrate or a layer adjacent to the substrate.
When the layer containing the curable resin is peeled off from the substrate or the adjacent layer on the substrate side to transfer the image formed by the electrophotographic method onto the support, the layer is transferred to the substrate or the substrate side. The layer containing the curable resin peels from the adjacent layer, covers the image and magnetic recording layer transferred onto the support, and protects the image and magnetic recording layer.

  The peel force at the interface between the layer containing the curable resin and the layer in contact with the substrate or the layer containing the curable resin in the transfer body is 0.098 N / cm or more and 4.90 N / cm or less ( 10 gf / cm or more and 500 gf / cm or less), preferably 0.196 N / cm or more and 3.92 N / cm or less (20 gf / cm or more and 400 gf / cm or less), more preferably 0.490 N / cm or more. More preferably, it is 2.41 N / cm or less (50 gf / cm or more and 250 gf / cm or less).

When the peeling force is less than 0.098 N / cm (10 gf / cm), the release layer and the layer containing the curable resin are easily peeled off, and the curable resin is applied to the fixing device of the electrophotographic apparatus at the time of image fixing. The contained layer is transferred, or when a magnetic information recording medium is produced, a slip occurs at the interface between the layer containing the curable resin and the adjacent layer on the substrate or the substrate side, and finally the image May be disrupted and transferred. On the other hand, if the peeling force exceeds 4.90 N / cm (500 gf / cm), a layer partially containing a curable resin may remain on the surface of the substrate or the adjacent layer on the substrate side. In some cases, defects on the surface of the magnetic information recording medium are caused.
Here, the peeling force is a measured value when measurement is performed according to the 180-degree peeling adhesive strength in the measurement of adhesive strength according to JIS standard Z0237.

The thickness of the heat-sealing layer (or all layers remaining on the support side together with the heat-sealing layer after the peeling step) is preferably in the range of 5 μm to 20 μm, and in the range of 7 μm to 10 μm. It is more preferable that
When the thickness of the heat fusion layer exceeds 20 μm, the distance in the medium thickness direction from the surface on the side where the heat fusion layer of the magnetic information recording medium is provided to the magnetic recording layer becomes too thick. In some cases, reading output of magnetic information by the magnetic information reading means becomes low, and reading errors and the like are likely to occur. On the other hand, if the thickness of the heat fusion layer is less than 5 μm, it may be difficult to protect the image or the magnetic recording layer provided at the interface between the heat fusion layer and the support.

  The thickness of the substrate is preferably in the range of 50 μm to 200 μm, more preferably in the range of 75 μm to 150 μm. If the thickness is less than 50 μm, the image forming apparatus may cause a conveyance failure, and if it exceeds 200 μm, the image quality may be deteriorated in the joining process.

The size of the transfer body is not particularly limited, but when the support is a fixed size such as A4 or A3, it is preferable that the size is the same as this. In addition, as described above, when a magnetic information recording medium is manufactured using a small-sized support body and a holding body, the size of the transfer body is the same size as the holding body or the same size as the support body. It is preferable.
In the case of using the holding body, when the transfer body and the holding body are overlapped so that the four corners coincide with each other, the image faces a desired position on the surface of the supporting body held by the holding body. An image is formed on the surface of the transfer body. In order to facilitate such alignment, the surface of the transfer body has a contour line of the support held by the holding body, a line slightly outside the contour line, or a line of the support body. It is desirable that marks indicating four corners are formed together with the image.

-First transcript-
Next, each form of the transfer body described above will be described.
In the first form of the transfer body (hereinafter sometimes referred to as “first transfer body”), a release layer, a curable resin is provided on the surface of the substrate on which the heat-sealing layer is provided. A layer and a heat-sealing layer are sequentially provided.

  In the first transfer body, the curable resin layer is a layer containing the curable resin described above, and the curable resin layer is a layer that can be peeled from the release layer that is a layer adjacent to the substrate side. That is, in the peeling step, the curable resin layer is peeled from the release layer, and the curable resin layer and the heat-sealing layer cover the image and the magnetic recording layer transferred onto the support, and the image and the magnetic recording layer are It will be protected.

  In the first transfer body, since the heat fusion layer is provided on the curable resin layer, when an image is formed with toner on the heat fusion layer, the toner does not spread and the resolution is improved.

On the other hand, the heat sealing layer in the first transfer body preferably contains a thermoplastic resin and particles having a volume average particle diameter larger than the film thickness of the heat sealing layer. In this case, the heat-sealing layer contains particles larger than the thickness of the layer, and the release layer can transfer the image forming material described later to the support satisfactorily. It has excellent image fixing characteristics.
In addition, as described above, the total thickness of the heat fusion layer and the curable resin layer is in the range of 5 μm or more and 20 μm or less from the viewpoint of protecting the image and the magnetic recording layer and preventing reading errors of the magnetic recording information. However, the thickness of the heat-sealing layer is preferably in the range of 5 μm to 12 μm, more preferably in the range of 7 μm to 10 μm, after satisfying this condition. If the thickness of the heat-sealing layer is within the above range, embedding the image in the film thickness direction of the heat-sealing layer makes it difficult for image quality to deteriorate and also provides an effect of protecting the image.

The release layer includes a release material. Thereby, the peelability at the interface between the release layer and the curable resin layer can be ensured in the transfer step.
The releasable material is not particularly limited, but a silicone-based hard coat material can be used. The silicone-based hard coat material may include a condensate resin containing a silane-based composition or a material composed of a mixture of a condensate resin containing the silane-based composition and a colloidal silica dispersion.

The curable resin layer in the first transfer member constitutes a layer on one surface of the magnetic information recording medium, and has a function of protecting the image and the magnetic recording layer.
In order to exhibit this function, the curable resin layer needs to be resistant to scratches and drugs. Therefore, it is preferable to include a photocurable or thermosetting resin such as the silicone-based hard coat material described above. In addition to these, various materials can be added as necessary. Of the total resins constituting the curable resin layer, the silicone-based hard coat material is included in the range of 0.5% by mass to 98% by mass. Preferably, it is contained in the range of 1% by mass or more and 95% by mass or less. If the content of the silicone-based hard coat material is less than 0.5% by mass, peeling at the interface between the release layer and the curable resin layer may be difficult in the transfer step, and if it exceeds 98% by mass. In some cases, the image transfer or fixing state is deteriorated and the image quality is deteriorated.

Resin is contained in the heat sealing | fusion layer. As the resin, for example, one or more polyester resins or styrene acrylic resins are used. In general, polyester resins and styrene acrylic resins are used for image forming materials. Therefore, fixing the image forming material to the surface of the transfer body by incorporating a resin of the same type into the heat-sealing layer. Sex can be controlled appropriately. As the polyester resin, in addition to a general polyester resin, for example, a silicone-modified polyester resin, a urethane-modified polyester resin, an acrylic-modified polyester, or the like may be used.
In addition, the heat-sealable layer is made of natural wax, synthetic wax, releasable resin, reactivity, or the like in order to prevent adhesion and winding to the fixing member of the electrophotographic apparatus when fixing the image with the electrophotographic apparatus. A mold release agent such as a silicone compound or a modified silicone oil may be contained.

-Second transcript-
In the second form of the transfer body (hereinafter sometimes referred to as “second transfer body”), a heat-sealing layer is provided on the surface of the substrate. And a resin other than the curable silicone resin.
In the second transfer body, the heat fusion layer is a layer containing a curable resin, and the heat fusion layer is a layer that can be peeled from the substrate. This is because the resin constituting the heat-sealable layer is a mixed resin containing a curable silicone resin and a resin other than the curable silicone resin, so that it can be peeled off from the substrate, and an image formed by electrophotography is used. When transferred onto the support, the heat-sealing layer peels off from the substrate, covers the image and magnetic recording layer transferred onto the support, and protects the image and magnetic recording layer. Further, since the curable silicone resin is tough, it is excellent in scratch resistance of the magnetic information recording medium.

  As the curable silicone resin, a known curable silicone resin can be used. In order to promote the compatibility between the heat-fusible layer and the image at the time of fixing, an acrylic resin or a polyester resin used as a toner binder resin can be used. It preferably contains a curable silicone resin having excellent compatibility. Moreover, as resin other than curable silicone resin, it is preferable to use an acrylic resin or a polyester resin for the same reason.

The said curable silicone resin contained in a heat sealing | fusion layer is demonstrated below.
In general, silicone resins are classified according to their molecular structure into silicone resins having a linear structure, which is a material such as silicone oil and silicone rubber, and silicone resins having a three-dimensionally crosslinked structure. In addition, various properties such as releasability, adhesiveness, heat resistance, insulation, and chemical stability are determined by molecules (organic molecules) bonded to silicon atoms, the degree of polymerization thereof, and the like.

The curable silicone resin is preferably a silicone resin having a three-dimensionally crosslinked structure. A silicone resin having a three-dimensionally crosslinked structure is usually polymerized from polyfunctional (trifunctional or tetrafunctional) units and has a crosslinked structure.
A silicone resin having a linear structure has a low molecular weight, and as a silicone oil, an insulating oil, a liquid coupling, a buffer oil, a lubricating oil, a heating medium, a water repellent, a surface treatment agent, a mold release agent, Examples include those used for foaming agents, and silicone rubbers that are polymerized to a molecular weight (siloxane unit) of about 5,000 to 10,000 by heat curing after adding a vulcanizing agent.

  Curable silicone resins are classified according to their molecular weight units into silicone varnishes that are soluble in organic solvents and have a relatively low molecular weight, silicone resins with a high degree of polymerization, and the like. The curable silicone resin is classified into a condensation type, an addition type, a radiation type (ultraviolet ray curable type, an electron beam curable type), and the like, depending on a curing reaction in the generation stage. Further, depending on the application form, it is classified into a solvent type, a solventless type and the like.

  The reason why the heat-fusible layer needs to contain a curable silicone resin is as follows. That is, first, since the curable silicone resin has a low surface energy due to Si—O bonds, it is essentially excellent in releasability and incompatibility. However, since it is possible to develop excellent adhesiveness by controlling the curing conditions, it is possible to obtain a magnetic information recording medium having both image releasability and image fixability. Because.

There is no restriction | limiting in particular as curable silicone resin, Although it can select from well-known curable silicone resin, curable acrylic modified silicone resin (curable acrylic silicone resin) is especially preferable for the following reasons.
The curable acrylic silicone resin includes a silicone resin portion that is usually used as an image forming material and contains a styrene-acrylic resin or an acrylic chain having a high chemical affinity with a polyester resin in the molecule, thereby exhibiting releasability. Have both. Therefore, in one molecule, there are a part that easily adheres to the toner and a part that hardly adheres to the toner. Further, since these are homogeneously compatible, image peelability and image fixability are expressed on a molecular order.
In the case of the curable acrylic silicone resin, the ratio of the acrylic chain to the silicone chain, the curing conditions, the addition amount of the curable silicone compound and the modified silicone oil described later, and the like can be controlled to control the image fixability and image peelability. Can be controlled more freely.

As the curable silicone resin, a thermosetting silicone resin can also be particularly preferably used.
The thermosetting silicone resin has a lower surface hardness than the acrylic silicone resin known as a photo-curing type, and accordingly, the image forming material tends to be encased in the image receiving layer and tends to be excellent in image fixability. is there.
In addition, the thermosetting silicone resin has a high mold releasability compared to an acrylic silicone resin and the like, and as a result, is excellent in image peelability.
In the case of a thermosetting silicone resin, in the case of a mixed system of a silicone component and a non-silicone component, the image fixing property can be controlled by controlling the ratio, the curing conditions, and the addition amount of the curable silicone compound and the modified silicone oil. And image peelability can be further freely controlled.

  A mixture of an acrylic silicone resin and a thermosetting silicone resin can be preferably used. When mixing the acryl silicone resin and the thermosetting silicone resin, the mixing ratio will show an intermediate performance between the two, the ratio, the curing conditions, the addition amount of the curable silicone compound and the modified silicone oil, etc. By controlling this, it is possible to further freely control the image fixing property and the image peeling property.

  Suitable examples of the curable silicone resin include the following when classified into a condensation type, an addition type, and an ultraviolet curable type.

As the condensation type curable silicone resin, for example, a polysiloxane such as polydimethylsiloxane having a silanol group at the terminal is used as a base polymer, and polymethylhydrogensiloxane or the like is blended as a crosslinking agent, and an organic acid such as an organic tin catalyst. A curable silicone resin synthesized by heat condensation in the presence of a metal salt or amine, or a curable silicone synthesized by reacting a polydiorganosiloxane having a reactive functional group such as a hydroxyl group or an alkoxy group at the terminal. Examples thereof include polysiloxane resins synthesized by condensing a silanol obtained by hydrolyzing a resin, a trifunctional or higher functional chlorosilane, or a mixture of these with a monofunctional chlorosilane.
The condensed type is classified into a solution type and an emulsion type in terms of form, and any of them can be used preferably.

As an addition-type curable silicone resin, for example, a polysiloxane such as polydimethylsiloxane containing a vinyl group is used as a base polymer, and polydimethylhydrogensiloxane is blended as a cross-linking agent to react in the presence of a platinum catalyst. Examples thereof include a curable silicone resin synthesized by curing.
The addition type is classified into a solvent type, an emulsion type, and a useless type in terms of form, and any of them can be used preferably.

  Examples of the ultraviolet curable curable silicone resin include a curable silicone resin synthesized using a photocationic catalyst and a curable silicone resin synthesized using a radical curing mechanism.

  The content of the curable silicone resin in the heat-sealing layer is preferably 30% by mass or more and 100% by mass or less, and more preferably 50% by mass or more and 100% by mass or less. When the content is less than 30% by mass, the release performance may not be exhibited.

As the resin other than the curable silicone resin, an acrylic resin or a polyester resin excellent in compatibility with the toner is preferably used, but other hot-melt resins and curable resins can also be used.
The acrylic resin as a resin other than the curable silicone resin preferably has a glass transition point (Tg) in the range of 50 ° C to 120 ° C, and more preferably in the range of 60 ° C to 105 ° C.

  In addition to the acrylic resin and the polyester resin as the resin other than the curable silicone resin, the heat-sealing layer can be used in combination with other resins as necessary.

  In order to prevent adhesion and wrapping to the fixing member at the time of fixing the image, the heat-fusible layer is natural wax or synthetic wax which is a low adhesion material to the fixing member, or a release resin or reactive silicone. It is preferable to contain a compound, modified silicone oil, and the like.

The image and the magnetic recording layer will be protected. Moreover, since the curable silicone resin contained in the heat-sealing layer is tough, covering the image is excellent in scratch resistance.

-Support-
The support used in the present invention is not particularly limited as long as at least one surface contains a thermoplastic resin, but is most preferably a plastic sheet made of a thermoplastic resin. When the support is composed of two or more layers, the layer constituting at least one surface is a layer containing a thermoplastic resin, and the other layers are made of a thermosetting resin and / or a thermoplastic resin.

Resin or ink vehicle in which magnetic fine particles such as γ-Fe ₂ O ₃ are dispersed include butyral resin, vinyl chloride / vinyl acetate copolymer resin, urethane resin, polyester resin, cellulose resin, acrylic resin, styrene / male An acid copolymer resin or the like is used, and a rubber-based resin such as nitrile rubber or a urethane elastomer is added as necessary. The adhesive layer is not particularly limited as long as it has adhesiveness to the joint surface of the transfer body. However, a heat-melt adhesive (for example, vinyl chloride) that exhibits adhesiveness when melted by heating. -It is preferably composed of an adhesive such as a vinyl acetate copolymer resin, a polyester resin, a polyamide resin, or a polyurethane resin, either alone or in combination. As the release film, PET (polyethylene terephthalate) film, nylon, cellulose diacetate, polystyrene, polyethylene, polypropylene, polyester, polyimide, polycarbonate and other resin films, copper, aluminum and other metals, paper, impregnated paper, etc. Or it can combine and use as a composite_body | complex.

The total sum of the thickness of the magnetic material layer and the thickness of the adhesive layer (the thickness of the magnetic recording layer) is not particularly limited, but is practically preferably in the range of 1 μm to 100 μm, and is preferably 5 μm to 20 μm. Within the range of is preferable. Further, the shape of the magnetic tape is not particularly limited, but usually it is preferably a belt shape.
As such a magnetic tape, a commercially available product can be used, and examples thereof include Dynic: TSP407NR, TSP207NP3R, and Green Corporation: TAL N29.

-Retainer-
The holding body used in the production of the magnetic information recording medium of the present invention has at least a base and a holding member for holding a support on at least one side of the base.

-Substrate-
Here, it is preferable that the substrate used for the holding body has a size and a shape that can be easily handled in the process of forming the magnetic information recording medium by the apparatus for producing the magnetic information recording medium. Is not particularly limited as long as it has a size larger than the support to be held by the holding body, but it is more preferably a quadrangular shape within a range of 100 × 148 mm to 64 × 521 mm, and A3 (297 × 420 mm) or A4 (210 × 297 mm) or the like is more preferable.

  Further, the thickness of the substrate depends on the shape of the holding member provided on the surface of the substrate, but is preferably in the range of 75 μm to 500 μm. If the thickness of the substrate is less than 75 μm, the rigidity of the holding body is insufficient and the holding body is easily deformed, so that the support may be displaced and mechanical handling may be difficult. Further, when the thickness of the substrate exceeds 500 μm, it is difficult for heat to be transferred from the back surface to the support, and bonding between the transfer body and the support may be insufficient.

The material constituting the substrate is a material that can secure the rigidity of the holding body within the above-mentioned thickness range so that the support does not shift in the process of forming the magnetic information recording medium or mechanical handling becomes difficult. If it is, a well-known material can be utilized and you may use it in combination of 2 or more types.
For example, examples of the inorganic material include metals such as stainless steel and aluminum. Examples of the organic material include resins such as nylon, polytetrafluoroethylene (PTFE), polyamideimide, polyetheretherketone, polyphenylene sulfide, and polyacetal, wood such as firewood, and paper.

  Note that the surface of the base body on which the holding member is not provided holds a line or a support body slightly outside the area where the support body is held so that the area where the support body is held can be easily grasped visually. It is preferable that marks indicating the four corners of the area to be printed are printed.

-Holding member-
The holding member is provided with a holding member that holds the support on at least one side of the base.
The holding member is not particularly limited as long as it has a function capable of continuing to be fixed so that the support does not shift with respect to the plane direction of the base of the holder in the process of forming the magnetic information recording medium. A convex member provided on the surface is particularly preferable.
This convex member is provided on the surface of the base body and has a function of holding the support when its side surface is in contact with the side of the support. Therefore, if the convex member can achieve this function, the shape and arrangement position in the base plane direction are not particularly limited, but basically, the convex member is provided on the base surface along the outline of the support to be held. In addition, it is preferable to be disposed so as to be in contact with any of the four sides of the support.

  The convex member described above may be continuously provided on the surface of the base so as to surround an area where the support on the surface of the base is held. In this case, the displacement of the support can be prevented more reliably. In addition to this, when the support is composed of a plastic sheet containing a thermoplastic resin as a main component, this can be suppressed even when the support is easily deformed due to heating in the joining step. Therefore, it is possible to suppress elongation deformation in the planar direction of the magnetic information recording medium.

When the convex member is continuously provided on the surface of the base so as to surround the region where the support on the surface of the base is held, the convex member can also contribute to securing the rigidity of the base. Therefore, in order to ensure the rigidity of the entire holding body, the thickness of the substrate is more preferably 75 μm or more.
On the other hand, when the convex member is provided discretely so as to surround the region where the support on the substrate surface is held, it is difficult to make the convex member contribute to securing the rigidity of the holding body. Therefore, in order to ensure the rigidity of the entire holding body, the thickness of the base is more preferably 150 μm or more.

  The height of the convex member is not particularly limited as long as it can secure a function that allows the support to continue to be fixed so as not to be displaced with respect to the plane direction of the base of the holder in the process of forming the magnetic information recording medium. From the viewpoint of suppressing defects around the edge of the magnetic information recording medium, the thickness of the support is preferably in the range of 150 μm or more and the thickness of the support +60 μm or less, and the thickness of the support is −100 μm or more. More preferably, it is the same as the thickness of the support.

If the height of the convex member is less than the thickness of the support −150 μm, the pressing force applied to the periphery of the end of the support becomes too strong when the transfer body is pressed against the surface of the support held by the support. There is a case where deformation around the end of the information recording medium occurs. Further, when the image is formed up to the periphery of the end portion of the magnetic information recording medium, the image extension around the end portion may occur due to the deformation around the end portion.
Further, if the height of the convex member exceeds the thickness of the support +60 μm, the transfer body cannot contact the periphery of the end of the support when the transfer body is pressed against the surface of the support held by the support. When the image is formed up to the periphery of the end portion of the magnetic information recording medium, the image omission around the end portion of the magnetic information recording medium may occur.
In addition, since the thickness of the support used for the production of cards such as cash cards is usually 760 μm, from this viewpoint, the height of the convex member should be 610 μm or more and 820 μm so as to satisfy the above-mentioned range. Is particularly preferred.

  The material constituting the convex member is not particularly limited as long as it is not deformed and crushed when the transfer body is pressed against the holding body. For example, the same material as that constituting the substrate is used. Can do. In addition, the material which comprises a base | substrate and the material which comprises a convex member may be the same, or may differ.

On the other hand, the holding body in which the holding member is composed of a convex member may be disposable but is preferably reusable. However, when the image provided on the surface of the transfer body is made of a solid or liquid image forming material such as toner or ink, when the magnetic information recording medium is produced by repeatedly using the holder, the image of the toner or the like is formed on the surface of the convex member. The forming material may adhere and become contaminated. This contamination is particularly likely to occur when an image is provided up to the edge of the magnetic information recording medium. Therefore, when the surface of the convex member is contaminated with the image forming material, the image forming material on the surface of the convex member is transferred to another member, and eventually the image quality of the image formed on the magnetic information recording medium is deteriorated. There is a case to be.
For example, in the apparatus for producing a magnetic information recording medium, when the holders holding the support are stored in a stacked state, the image forming material on the surface of the convex member is on the substrate side of another adjacent holder. Furthermore, when the other holding body is transported, it is transferred again to the surface of the supporting body held by the holding body arranged in contact with the substrate side of this holding body to contaminate the surface of the supporting body. And so on.

  Therefore, in order to suppress the occurrence of this problem, it is preferable that a release layer is provided on the surface of the convex member. Examples of the material constituting the release layer include polytetrafluoroethylene, tetrafluoroethylene / perfluoroalkyl vinyl ether copolymer, tetrafluoroethylene / hexafluoropropylene copolymer, and tetrafluoroethylene / ethylene copolymer. Fluorine resin, silicone rubber and the like can be suitably used.

  Note that the surface of the convex member shows lines slightly outside the region where the support is held and the four corners of the region where the support is held so that the region where the support is held can be easily grasped visually. It is preferable that a mark or the like is printed.

On the other hand, as the holding member, in addition to the convex member described above, a belt member having both ends fixed to the base surface and / or the end surface can be used. The belt member can be held so that the support does not shift in the plane direction of the substrate by sandwiching the support in the gap between the belt member and the substrate surface. In order to perform this function reliably, for example, the belt member can be arranged on the surface of the base body at a position where two opposing corner portions of the support to be held can be sandwiched. In order to facilitate attachment of the support to the holding body and removal of the magnetic information recording medium from the holding body, one or both ends of the belt member may be detachable from the base.
As the belt member, for example, a resin film, a rubber band, or the like can be used. However, the belt member is preferably made of a material having heat resistance of 120 ° C. or higher.
On the other hand, when a magnetic information recording medium is formed using a holder having a belt member provided on a substrate, the image is preferably formed at some distance from the portion where the belt member is located. This is to prevent the occurrence of image omission.

  Further, the holding member may be configured to hold only one support, but in order to further improve the productivity of the magnetic information recording medium, the two or more supports are held. It is preferable to be configured to be able to.

Next, a specific example of the holding body will be described. FIG. 5 is a plan view showing an example of the holding body, and shows the surface of the holding body on which the holding member is provided.

The member 204 is arranged.

Note that FIG. 5 shows a holding body configured to hold one support, but a plurality of supports in which the holding bodies illustrated in these drawings are two-dimensionally arranged in a plane direction can be held. A holding body having a configuration may be used. This example is illustrated below.
FIG. 6 is a plan view showing another example of the holding body, and shows the surface of the holding body on the side where the holding member is provided with respect to the holding body that can hold up to six supports.
In the figure, 260 represents a holding body, and other symbols and shaded parts are the same as those shown in FIG. The rectangular holding body 260 shown in FIG. 6 has a configuration in which 2 units in the lateral direction and 3 units in the longitudinal direction are arranged when the holding body 210 shown in FIG. is there.

-Preparation of transfer body 1-
A PET film (Lumirror 100T60, manufactured by Toray Industries, Inc., thickness: 100 μm) was used as a substrate, and the non-bonding side layer coating solution A-1 was applied to one side of the substrate using a wire bar, and the coating was performed at 110 ° C. for 30 seconds. It was made to dry and the non-joining surface side layer with a film thickness of 0.15 micrometer was formed. The surface resistivity of the surface of the non-joint side layer was 8.2 × 10 ⁹ Ω.
In addition, the release layer coating solution 1 is similarly applied to the other surface (untreated surface) of this substrate using a wire bar, dried at 120 ° C. for 30 seconds, and separated with a thickness of 0.5 μm. A mold layer was formed. Subsequently, on this release layer, a heat fusion layer coating liquid B-3 was further applied using a wire bar and dried at 120 ° C. for 60 seconds to form a heat fusion layer having a thickness of 5 μm. The transfer body 1 was produced. The surface resistivity (bonding surface) on which the heat-fusible layer was formed was 1.7 × 10 ¹⁰ Ω.

-Formation of magnetic recording layer-
For the formation of the magnetic recording layer, a strip-shaped (210 mm × 7 mm) black magnetic tape (Dynic: TSP207H INR) was used.
The magnetic tape was provided with a release film, a magnetic material layer made of an inorganic magnetic material and in direct contact with the release film, and a release film of the magnetic material layer on one side of the release film. The magnetic recording layer is composed of an adhesive layer disposed on the surface opposite to the side surface.
This magnetic tape is placed at a predetermined position on the bonding surface of the transfer body 1 and heat-treated at 100 ° C., 10 s, 5 kgf / cm ² , and then the release film is peeled off to perform magnetic recording on the bonding surface of the transfer body 1. The layer was thermally transferred, and then the transfer body 1 was cut into A4 size (210 mm × 297 mm).
Note that the thermal transfer of the magnetic tape and the cutting of the transfer body are the same as the longitudinal direction of the transfer body after cutting, and the short side direction of the transfer body after cutting matches the longitudinal direction of the strip-shaped magnetic recording layer. It was carried out so that three strip-shaped magnetic recording layers could be arranged at intervals.

-Toner image formation-
Subsequently, the magnetic recording layer was formed with a color mirror image image including a solid image at a predetermined position on the transfer member bonding surface on which the magnetic recording layer was formed by a modified color copier DocuColor 1256 manufactured by Fuji Xerox Co., Ltd. It was formed so as not to overlap with the part.
At this time, the transfer body was supplied to the copying machine so that the short side direction coincided with the paper feeding direction. Thereafter, when a portion where the magnetic recording layer after image formation was formed was visually confirmed, no mixing of bubbles was observed between the magnetic recording layer and the transfer body, and the appearance was good.
In addition, the image has a pattern (85.6 mm × 54 mm) corresponding to the support to be used, two images at equal intervals in the short direction, and the like in the longitudinal direction so as to exclude the portion where the magnetic recording layer is formed. A total of six were formed so that three were arranged at intervals.
Here, the melting temperatures of the magenta, cyan, yellow, and black toners used for forming the image are all 130 ° C., and the fixing is performed so that the surface temperature of the transfer member is in the range of 95 to 100 ° C. Implemented.
For reference, when the transfer body is supplied to the copying machine so that the short side direction is orthogonal to the paper feeding direction, air bubbles are mixed between the magnetic recording layer and the transfer body and the appearance is poor. It was confirmed that even if a magnetic information recording medium was produced using this transfer body, it was at a level causing quality problems.
