  Embodiments of an information recording medium, an IC card, and an IC card manufacturing method according to the present invention will be described below. The embodiment of the present invention shows the most preferable mode of the present invention, and the present invention is not limited to this.

  FIG. 1 is a diagram showing a dry offset printing method of the present invention. In the dry offset printing method, an information recording medium 74 that supplies ink from the ink supply roller 70 to the plate cylinder 71 and further supplies the ink from the plate cylinder 71 to the blanket cylinder 72 and conveys between the blanket cylinder 72 and the impression cylinder 73. Print on. The information recording medium 74 includes printing paper.

  In general, offset printing is a printing system that does not transfer the ink attached to the plate directly to paper, but transfers it from the plate to a rubber sheet (off) and transfers (set) it to paper, for example, Japan Printing Technology Association. It is described in publications such as “lithographic printing technology”, “new printing technology overview”, “offset printing technology”, “plate making / printing somewhat understandable book”.

  In the case of the present invention, it is preferable to perform standard format printing on the information recording medium by the dry offset printing method. The dry offset printing method is a “offset printing method of letterpress” in which “letter plate” is used instead of “flat plate” as a printing plate. Since this dry offset printing method does not require dampening water unlike a lithographic plate, there is little waste paper and the stability of printing density and registration accuracy is excellent. It is also possible to easily print on an information recording medium that is weak against water.

  The relief plate of the present invention is preferably a relief plate produced by a CTP (Computer to Plate) method from the viewpoint of dimensional accuracy. CTP (Computer To Plate) refers to a method of creating a printing plate by directly imaging a digital original to a printing plate with a laser. Conventionally, a plate-making film was created from a digital document, and this film and the printing plate were closely exposed and developed to produce a printing plate. Therefore, there are many processes until the printing plate is created, and dimensional accuracy deteriorates. However, it is preferable in the present invention because the number of processes is reduced and the dimensional accuracy is excellent by preparing a printing plate with the CTP in advance.

  As the CTP output machine, a CTP output machine capable of directly engraving with a laser and producing a plate without development is preferable. One example is the ZED Mini “ZED Mini” series. Further, as a plate used in such a CTP output machine, a photosensitive resin relief plate, for example, “Toreleaf” series manufactured by Toray Industries Co., Ltd., “Printite” series manufactured by Toyobo Co., Ltd., etc. is preferable in the present invention. Further, among these photosensitive resin relief plates, it is more preferable that the support is “steel”, that is, a metal, because the dimensional accuracy is improved. Moreover, it is more preferable that the hardness of the resin part is 65 degrees or more because the dimensional accuracy is improved. When the hardness of the resin part is smaller than 65 degrees, the printed matter is thick due to the pressure (printing pressure) during printing, so that the dimensional accuracy is inferior. In addition, the hardness of the resin described here indicates durometer type D (Shore D) of ISO 7619.

  The relief depth is preferably in the range of 0.14 to 0.3 mm. More preferably, it is the range of 0.19-0.25 mm. If it is smaller than 0.14 mm, the ink adheres to the non-image area and stains occur, which is not preferable. If it is larger than 0.3 mm, the image area is crumpled and printing troubles occur, which is not preferable.

  FIG. 2 shows an information recording medium 74 of the present invention, which is a card base sheet on which a fixed format 75 for an ID card is applied in a multi-sided manner by a dry offset printing method. A registration mark 76 for punching is provided. As shown in FIG. 2, the standard format 75 of the present invention includes “XXX employee ID”, “name”, “ID number”, “affiliation”, and the like. In the case of an ID card, it is preferable that a fixed format is provided in a multi-faceted manner from the viewpoint of productivity and cost. For example, if the card portions (25 in FIG. 2) are formed in a state where the card portions are arranged in a matrix with 5 rows in a vertical direction and 5 spaces in a predetermined interval, a large amount can be produced and productivity is improved. And it becomes low cost.

  The information recording medium 74 of the present invention preferably has a known image receiving layer capable of recording information by a sublimation thermal transfer recording method, a melt thermal transfer recording method, an electrophotographic method, or an ink jet method. Among them, the image receiving layer according to the present invention preferably uses a gradation information-containing image by a sublimation type thermal transfer method and a character information-containing image by a sublimation type thermal transfer method or a melt type thermal transfer method. In particular, the dyeing property of the sublimable dye, or the dyeing property of the sublimable dye, and the adhesiveness of the hot-melt ink must be good. In order to impart such special properties to the image-receiving layer, it is necessary to appropriately adjust the types of binders and various additives and their blending amounts as described later.

  Hereinafter, the components forming the image receiving layer will be described in detail.

  As the binder for the image receiving layer in the present invention, a conventionally known binder for a sublimation type thermal transfer recording image receiving layer can be appropriately used. As the main binder, various binders such as vinyl chloride resin, polyester resin, polycarbonate resin, acrylic resin, polystyrene resin, polyvinyl acetal resin, and polyvinyl butyral resin can be used.

  However, if there is a practical requirement for an image formed by the present invention (for example, a predetermined heat resistance is required for the issued ID card), the binder is set so as to satisfy such a requirement item. It is necessary to consider the types or combinations of these. Taking heat resistance of the image as an example, if heat resistance of 60 ° C. or higher is required, it is preferable to use a binder having a Tg of 60 ° C. or higher in consideration of bleeding of the sublimable dye.

  Moreover, when forming an image receiving layer, it may be preferable to contain a metal ion containing compound as needed, for example. This is particularly the case when the heat transfer compound reacts with the metal ion-containing compound to form a chelate.

Examples of the metal ions constituting the metal ion-containing compound include divalent and polyvalent metals belonging to Groups I to VIII of the Periodic Table. Among them, Al, Co, Cr, Cu, Fe, Mg , Mn, Mo, Ni, Sn, Ti, Zn and the like are preferable, and Ni, Cu, Co, Cr, Zn and the like are particularly preferable. As the compound containing these metal ions, inorganic or organic salts of metals and complexes of the metals are preferable. As a specific example, a complex represented by the following general formula containing Ni2 ⁺ , Cu2 ⁺ , Co2 ⁺ , Cr2 ⁺ and Zn2 ⁺ is preferably used.
[M (Q1) x (Q2 ) y (Q3) z] P + · (L -) P
In the formula, M represents a metal ion, preferably Ni2 ⁺ , Cu2 ⁺ , Cr2 ⁺ , Co2 ⁺ , or Zn2 ⁺ . Q1, Q2 and Q3 each represent a coordination compound capable of coordination with a metal ion represented by M, and may be the same or different from each other. These coordination compounds can be selected from, for example, coordination compounds described in Chelate Science (5) (Nan Edo). L ^- represents an organic anion group, and specific examples include tetraphenyl boron anion and alkylbenzene sulfonate anion. x represents an integer of 1, 2 or 3, y represents 1, 2 or 0, and z represents 1 or 0. In these, the complex represented by the above general formula is tetradentate or hexadentate. It is determined by the coordination or by the number of ligands of Q1, Q2 and Q3. p represents 1 or 2. Specific examples of this type of metal source include those exemplified in US Pat. No. 4,987,049. When the metal ion-containing compound is added, the addition amount is preferably 0.5 to 20 g / m ^{2 and} more preferably ¹ to 15 g / m ² with respect to the image receiving layer.

  Further, it is preferable to add a release agent to the image receiving layer. As an effective mold release agent, those compatible with the binder to be used are preferable, and specifically, modified silicone oil and modified silicone polymer are typical, for example, amino-modified silicone oil, epoxy-modified silicone oil, polyester-modified silicone. Examples thereof include oil, acrylic-modified silicone resin, and urethane-modified silicone resin. Of these, the polyester-modified silicone oil is particularly excellent in that it prevents fusion with the ink sheet but does not hinder the secondary processability of the image receiving layer. The secondary processability of the image-receiving layer refers to a writing property with magic ink, a laminating property that causes a problem when protecting a formed image, and the like. In addition, fine particles such as silica are also effective as a release agent. When secondary workability is not a problem, the use of a curable silicone compound is also effective as a measure for preventing fusion. Ultraviolet curable silicone, reaction curable silicone, and the like are available, and a great mold release effect can be expected.

  The image-receiving layer in the present invention is prepared by preparing a coating solution for an image-receiving layer obtained by dispersing or dissolving the forming component in a solvent, applying the coating solution for the image-receiving layer to the surface of the support, and drying the coating solution. Can be manufactured.

  The thickness of the image receiving layer formed on the surface of the support is generally 1 to 50 μm, preferably about 2 to 10 μm. In the present invention, a cushion layer or a barrier layer may be provided between the support and the image receiving layer. When the cushion layer is provided, there is little noise, and an image corresponding to the image information can be transferred and recorded with good reproducibility. Examples of the material constituting the cushion layer include urethane resin, acrylic resin, ethylene resin, polypropylene resin, butadiene rubber, epoxy resin, and photocurable resin described in Japanese Patent Application No. 2001-16934. The thickness of the cushion layer is usually 1 to 50 μm, preferably 3 to 30 μm.

  Examples of the support of the present invention include, for example, polyester resins such as polyethylene terephthalate, polybutylene terephthalate, polyethylene terephthalate / isophthalate copolymer, polyolefin resins such as polyethylene, polypropylene, and polymethylpentene, polyvinyl fluoride, polyvinylidene fluoride, Polyfluorinated ethylene resins such as polytetrafluoroethylene and ethylene-tetrafluoroethylene copolymer, polyamides such as nylon 6 and nylon 6.6, polyvinyl chloride, vinyl chloride / vinyl acetate copolymer, ethylene / Vinyl acetate copolymer, ethylene / vinyl alcohol copolymer, polyvinyl alcohol, vinyl polymers such as vinylon, biodegradable aliphatic polyester, biodegradable polycarbonate, biodegradable polylactic acid, biodegradable polyvinyl alcohol , Biodegradable resins such as biodegradable cellulose acetate and biodegradable polycaprolactone, cellulose resins such as cellulose triacetate and cellophane, methyl polymethacrylate, ethyl polymethacrylate, polyethyl acrylate, polyacryl Acrylic resin such as butyl acid, synthetic resin sheet such as polystyrene, polycarbonate, polyarylate, polyimide, or paper such as fine paper, thin paper, glassine paper, sulfuric acid paper, single layer of metal foil, or more than two layers The laminated body of this is mentioned.

  As for the thickness of the support body of this invention, 75-200 micrometers is preferable. If it is thicker than 200 μm, the image-receiving sheet becomes heavy and the blocking prevention effect is lowered. When the thickness is less than 75 μm, rigidity (strain) is lowered, and handling properties such as wrinkles and creases are formed, which is not preferable.

  In the case of this invention, the card | curd base material sheet | seat which preceded can also be used as a sheet material for IC cards.

  FIG. 3 is a plan view showing an example of an IC card. In FIG. 3, the IC card 1 is provided with an inlet 4 having an IC module 2 composed of an antenna coil 2b as a signal transmission / reception unit for an IC chip 2a and R / W (read / write). The personal identification information 5 includes a “face image portion 5a” and a “character information portion 5b”. The face image is preferably formed by a sublimation thermal transfer method because the image can be formed relatively easily. The character information is formed by a sublimation thermal transfer method or a melt thermal transfer recording method. The personal identification information 5 can be formed by an electrophotographic method or an ink jet method.

  4 is a cross-sectional view schematically showing the layer structure of the IC card of FIG. As the sheet material, at least a card base sheet which is the information recording medium 74 of the present invention is used. The card base sheet has a support 74a and an image receiving layer 74b. A format 75 is printed on the image receiving layer 74b. The card base sheet is provided with a second sheet material 78 via an adhesive 77, and the adhesive 77 encloses the inlet 4 having the IC module 2. As the sheet material, at least when the base material sheet for card is used as the information recording medium 74 of the present invention and the information recording medium of the present invention is used for only one of them, the other second sheet material 78 is ahead. The same “support” can be used. Further, a fixed information printing layer or writing layer may be formed on the support. For example, the writing layer can be formed by coating a polyester resin or the like with a white pigment such as silica dispersed therein.

  In this way, in an IC card formed by laminating an IC module and an adhesive between at least two sheet materials, the sheet material is a base material sheet for cards, and a fixed format 75 is applied in a multi-faceted manner. As the personal identification information 5, the “face image portion 5a” and the “character information portion 5b” can be formed by a sublimation thermal transfer method, a melt thermal transfer recording method, an electrophotographic method, or an ink jet method.

  As the adhesive 77, it is preferable to use a hot-melt adhesive. Even after the hot melt adhesive is once formed into a sheet shape, the function as an adhesive is restored again when heated to a certain temperature. Examples of the hot melt adhesive include moisture curable and photo curable reactive hot melt adhesives, and moisture curable hot melt adhesives are more preferable. Moisture curable reactive hot melt adhesives are disclosed in JP 2000-036026, JP 2000-21855, JP 2000-21278, JP 2000-21855, and Japanese Patent Application 2000-369855.

  Here, an example of a method for producing an IC card using a hot melt adhesive will be given. In producing the IC card, first, a hot melt adhesive is applied to a predetermined thickness on the front and back sheets with an applicator. As a coating method, a normal method such as a roller method, a T-die method, or a die method is used. The IC module is mounted between the upper and lower sheets coated with the adhesive. The adhesive applied before mounting may be preheated with a heater or the like. After that, as shown in FIG. 6, the IC module mounted between the upper and lower sheets is pressed for a predetermined time with a press heated to the bonding temperature of the adhesive. Alternatively, instead of pressing with a press, the sheet may be pressed with a roll while transporting the sheet in a constant temperature bath. Further, it is effective to perform vacuum pressing in order to prevent bubbles from entering during bonding. In addition, since it is possible to prevent the expensive IC chip 2a from being inserted in a location where the standard format printing is defective, it is preferable to perform the standard format printing in advance before the sheet material is bonded. When a standard format 75 is applied after pasting, if a printing defect occurs for some reason, it is preferable to dispose of the expensive IC chip 2 and it becomes difficult to separate it from the IC chip 2. Absent.

  FIG. 5 is a schematic view of a punching device. The punching block 10 is composed of a block in which a lower blade 10b that is paired with the upper blade 10a is arranged. The upper blade 10a moves up and down to engage with the lower blade 10b and punch the IC card I. . Although FIG. 5 shows a punch-and-die method, there is no particular limitation. For example, a Thomson blade method that does not use the lower blade 10b may be used. Further, the information recording medium 74 is a punched IC card obtained by laminating a card base sheet to form a card sheet, and sequentially punching card portions from the card sheet for each row using a press die of the punching block 10. The variation in the format position of 1 is reduced, the productivity is improved, and the cost is reduced.

  In the case of the present invention, the registration mark detector 11 detects the registration mark 76 provided on the multi-sided sheet of the information recording medium 74, and corrects the position of the information recording medium 74 in the X, Y, and θ directions. In view of productivity and cost, a method of creating punched cards while transporting at a constant interval is preferable. In this way, the registration mark 76 of the card base sheet that is a multi-sided sheet is detected, and the position of the card base sheet in the vertical (X) direction, horizontal (Y) direction, and oblique (θ) direction is corrected. This improves the punching accuracy.

  As shown in FIG. 5, when using a die in which the punching block 10 is integrated for a plurality of cards, it is preferable to use a CTP method printed with high dimensional accuracy as previously described. If the dimensional accuracy is poor, the variation in the format position of the punched IC card becomes large and a defective card is generated. As a result, productivity and cost are deteriorated.

  In this way, after the IC card 1 is punched, personal identification information including character information and face image information is applied to the outer surface of the IC card 1 at least by a sublimation thermal transfer recording method, a melt thermal transfer recording method, and an electrophotographic method. Or it is recorded by either the inkjet method, and authentication cards such as employee ID cards, employee ID cards, membership ID cards, student ID cards, alien registration cards, and various licenses are manufactured.

[Example]
Example 1
"Creating an information recording medium"
An information recording medium having a sublimation type thermal transfer image receiving layer shown below on one side of a white PET film support having a thickness of 188 μm was prepared. The image-receiving layer for sublimation thermal transfer is composed of a material that traps and fixes the dye when the sublimation dye ink is heated and thermally diffused by the thermal head. Dissolve the vinyl chloride powder in the methyl ethyl ketone solvent and use the gravure coater many times. It was formed by coating and then drying to evaporate the solvent. The thickness of the image receiving layer for sublimation thermal transfer is 2.5 μm.

"Standard format printing"
On the information recording medium having the sublimation thermal transfer image-receiving layer thus prepared, the format printing (XX employee ID, name, ID number, affiliation, ruled line) for the card shown in FIG. It was carried out by a dry offset printing method using a resin relief plate. The print quality (dirt, lack of characters and ruled lines) was evaluated and shown in Table 2.

As the photosensitive resin relief plate, Trelief WS43HII: manufactured by Toray Industries, Inc., whose support is steel, was used, and exposure of 4000 mj / cm ² as an integrated light amount was performed on the entire surface of the plate in advance. Next, a carbon dioxide laser engraving machine (ZED mini 1000: manufactured by ZED Instruments) was used as a CTP output machine. The relief depth of the prepared resin relief printing plate was measured with a dial gauge (the average value measured in the plate surface at N = 10), and the hardness of the resin part was measured according to ISO 7619 standard (durometer type D). Asker rubber hardness Measured with a total D type (manufactured by Kobunshi Keiki Co., Ltd.) These are shown in Table 1 below.

"Creating an IC card"
This image receiving sheet is used as a first sheet material, and the second sheet material has a writing layer on one side of a 188 μm white PET film support. The writing layer was formed by diffusing calcium carbonate and silica fine particles in a polyester emulsion, and was formed by applying a gravure coater or the like and then drying to evaporate the solvent. The thickness of the writing layer is almost the same as that of the image receiving layer. Moisture-curing hot melt adhesion with a T-die type applicator to the surface opposite to the surface having the image receiving layer of the first sheet material and the surface opposite to the surface having the writing layer of the second sheet material Coating agent (Sekisui Chemical Co., Ltd. product: Sdyne 2013MK), sandwiching the IC module between the first and second sheet materials, using an end plate flat heat press, heating at 90 ° C., 5 kgf / cm ² , Thermocompression bonding was performed under conditions for 30 seconds to prepare a 25-side IC card sheet. Subsequently, IC cards were created by sequentially punching out one row at a time with a punching machine having punching blocks for five cards.
"Method of describing personal identification information on personal authentication card and surface protection method"
Next, an IC card provided with personal identification information including a name and a face image was created as follows.

The variations in the recording positions X and Y directions of this personal identification information were evaluated at N = 100 and are shown in Table 2.
(Example 2)
Except that the measurement result of the relief depth was 0.22 mm, an IC card provided with personal identification information consisting of a name and a face image was created in the same manner as in Example 1, and the recording position X, Y direction of this personal identification information The variation was evaluated at N = 100 and is shown in Table 2.
(Example 3)
Except that the measurement result of the relief depth was 0.30 mm, an IC card provided with personal identification information consisting of a name and a face image was created in the same manner as in Example 1 and the personal identification information was recorded in the X and Y directions The variation was evaluated at N = 100 and is shown in Table 2.
(Comparative Example 1)
The same plate as in Example 1 was used except that the relief depth measurement result was 0.13 mm. However, due to the occurrence of scumming in the standard format printing (a phenomenon in which ink adheres to the non-image area), the IC was used. I did not create a card.
(Comparative Example 2)
As a photosensitive resin letterpress, the support is a polyester film, Trelief WF50II: manufactured by Toray Co., Ltd., and a resin letterpress is created with a CTP output machine in the same manner as in Example 1 to measure the depth of relief and the hardness of the resin part. After that, standard format printing was performed, but the image portion was missing, and a printed matter with poor quality was finished. Next, an IC card with personal identification information consisting of name and face image was created. The variations in the recording positions X and Y directions of this personal identification information were evaluated at N = 100 and are shown in Table 2.
(Comparative Example 3)
Evaluation was performed in the same manner as in Example 1 except that the printing in the standard format was changed to the following, and the results are shown in Table 2.
The printing plate was changed to a photosensitive lithographic plate prepared by analog plate making instead of the resin relief plate which was output by CTP.
As for the printing method, standard format printing was performed by offset printing using dampening water instead of the dry offset printing method. In addition, since it is not a resin letterpress, the depth of relief and the hardness measurement of the resin part were not performed.

Criteria for evaluating print quality ○: No non-image area is stained. There is no lack of fixed-format characters or ruled lines.
