The medium has a certain economic value and effect, and individual information such as a valid period, a section, a name, and an age is written (printed) for each sheet to be a forgery prevention medium. As a method for printing personal information, there are a thermal transfer system using a thermal transfer film of a melt transfer type or a sublimation type, and an ink jet system. An intermediate transfer recording medium used as a conventional anti-counterfeit medium first prints an image such as personal information, and then transfers it to the transfer target in accordance with the image. Therefore, it is necessary to align the image with the intermediate transfer recording medium. There was no. However, in the patch intermediate transfer recording medium in which the transfer portion is cut in advance in the form of a patch, an image such as different personal information is printed on each patch, so that the image is printed at a predetermined position on the patch with high positional accuracy. There must be. Thereafter, when transferring to the transfer target, the patch on which the image has been printed must be transferred to the transfer target accurately and with high positional accuracy so that there is no deviation from the transfer target. In addition, the patch intermediate transfer recording medium must be manufactured at a low cost. The anti-counterfeit medium after transfer has excellent durability such as scratch resistance and solvent resistance against external force during use, and the image is tampered with security to prevent unauthorized forgery, alteration, unauthorized use, It is also necessary to have excellent design properties.
Therefore, the patch intermediate transfer recording medium used for the forgery prevention medium can accurately print an image such as personal information of a different owner for each sheet to a predetermined position of the patch, and accurately position the patch on which the image is printed. It is required to transfer to a transfer medium with high accuracy, to be manufactured at a low cost, to have excellent scratch resistance and solvent resistance after transfer, and to have excellent security and design.

(Prior Art) Conventionally, a method is known in which a register mark (corresponding to a timing mark of the present application) is attached to a blank portion of a hologram image, and a reading position is corrected by a sensor (see, for example, Patent Document 1). However, the timing mark of the light diffraction structure has a drawback that a special sensor is required because the diffraction light from the mark must be read.
Further, a method of reading light from a mark with a line sensor is known (for example, see Patent Document 2). However, the illumination light source for illuminating the mark has a problem that a special light source is required to illuminate the laser beam with slit light.

  (Patch Intermediate Transfer Recording Medium) In the manufactured patch intermediate transfer recording medium 20, as shown in FIG. 1, the patch 21 is laminated on the surface of the peelable resin layer 33 of the support member 30 so as to be peelable. The patch 21 is a patch formed by half-cutting the transfer portion of the transfer material 10. The transfer material 10 includes a transparent base material 11, a transfer portion (half-cut into a patch) composed of a hologram layer 15, a transparent reflection layer 17 and a receiving layer 23 on one surface of the transparent base material 11, and the other side.

The patch 21 includes a transparent substrate 11, a hologram layer 15, a transparent reflection layer 17, and a receiving layer 23.

  (Method for Producing Patch Intermediate Transfer Recording Medium) The method for producing the patch intermediate transfer recording medium 20 of the present invention will be described in the order of steps, including materials and methods used in the steps.

  (Transfer material) The transfer material preparation step of S1 includes (1) a transparent base material, a hologram layer, a transparent reflective layer and a receiving layer provided on one surface of the transparent base material, and a peelable resin layer provided on the other surface. This is a step of preparing a transfer material. The transfer material 10 includes a transparent substrate 11, a hologram layer 15, a reflective layer 17, and a receiving layer 23 on one surface of the transparent substrate 11, and a peelable resin layer 33 on the other surface. As shown in FIG. 1, the transfer material 10 composed of the peelable resin layer 33 / transparent substrate 11 / hologram layer 15 / reflective layer 17 / receiving layer 23 has a patch 21 at a portion cut by the half-cut process. The toner is transferred to the transfer target 101 and functions as a protective layer. One part of the peelable resin layer 33 may be transferred to the transfer target 101, or one layer may be transferred to the transfer target 101 when the peelable resin layer 33 has two layers.

  (Transparent Substrate) As the transparent substrate 11, various materials can be applied depending on the use as long as it has durability such as transparency, weather resistance, friction resistance and chemical resistance. For example, polyester resins such as polyethylene terephthalate and polyethylene naphthalate, polyamide resins, vinyl resins such as polyvinyl chloride, acrylic resins, imide resins, engineering resins such as polyarylate, polycarbonate, cyclic polyolefin resins, cellophane Examples thereof include cellulosic films. The transparent substrate 11 may be a copolymer resin containing these resins as a main component, a mixture (including an alloy), or a laminate composed of a plurality of layers.

  The transparent substrate 11 may be a stretched or unstretched film, but a film stretched in a uniaxial direction or a biaxial direction is preferable for the purpose of improving strength. A thickness of about 2.5 to 50 μm is usually applicable, but 2.5 to 25 μm is preferable. Prior to coating, the transparent substrate 11 is subjected to easy adhesion treatment such as corona discharge treatment, plasma treatment, primer (also called an anchor coat, adhesion promoter, or easy adhesive) coating treatment, alkali treatment, etc. May be. Moreover, you may add additives, such as a filler, a plasticizer, a coloring agent, and an antistatic agent, as needed. A biaxially stretched polyethylene terephthalate film is preferably used because of its good heat resistance and mechanical strength.

  (Hologram layer) The hologram layer 15 may contain an ionizing radiation curable resin as a main component, and may contain additives such as silicone and filler as necessary. The ionizing radiation curable resin is a cured product of an ionizing radiation curable resin. The ionizing radiation curable resin is preferably (1) an isocyanate having three or more isocyanate groups in the molecule, and (2) a hydroxyl group in the molecule. And a polyfunctional (meth) acrylate having at least one (meth) acryloyloxy group, or (3) urethane (meta) which is a reaction product of a polyhydric alcohol having at least two hydroxyl groups in the molecule. ) An ionizing radiation curable resin containing an acrylate oligomer is used, preferably including polyethylene wax, applied, dried, and cured with ionizing radiation to obtain an ionizing radiation curable resin. Specifically, the photocurable resin etc. which are indicated by JP, 2001-329031, A can be illustrated. Specific examples include MHX405 varnish (made by The Inktec Co., Ltd., ionizing radiation curable resin product name) and Iupimer UV · V3031 (manufactured by Mitsubishi Chemical Co., Ltd., product name of ionizing radiation curable resin).

  (Hologram layer formation) The hologram layer 15 is formed by adding the above-mentioned ionizing radiation curable resin and, if necessary, silicone, filler, photopolymerization initiator, plasticizer, stabilizer, surfactant, etc. to the solvent. It may be dispersed or dissolved, applied by a known coating method such as roll coating, gravure coating, comma coating, die coating and the like, dried, and reacted (cured) with ionizing radiation after shaping the hologram. The thickness of the hologram layer 15 is usually about 1 to 10 μm, preferably 2 to 5 μm.

  (Hologram) In the transfer material 10 of the present invention, a light diffractive fine unevenness is formed on the surface of the hologram layer 15 on the receiving layer 23 side to form the hologram layer 15, and the reflective layer 17 is provided on the fine uneven surface. Thus, the high designability and anti-counterfeiting property of the hologram can be imparted.

  (Hologram) Next, predetermined fine unevenness (relief structure) such as a hologram that exhibits a light diffraction effect is formed on the surface of the hologram layer 15 and cured. A hologram is a recording of interference fringes due to the interference of light between object light and reference light in an uneven relief shape. For example, a laser reproduction hologram such as a Fresnel hologram, a white light reproduction hologram such as a rainbow hologram, There are color holograms utilizing the above principle, computer generated holograms (CGH), holographic diffraction gratings and the like. The relief shape is a concavo-convex shape, and is not particularly limited, and may have a fine concavo-convex shape such as light diffusion, light scattering, light reflection, light diffraction, etc., such as Fourier transform or lenticular lens. , A light diffraction pattern, and a moth eye. Further, although it does not have a light diffraction function, it may be a hairline pattern, a mat pattern, a line pattern, an interference pattern, or the like that expresses a unique glitter.

  A relief shape is formed (also referred to as replication) on the surface of the hologram layer 15. Hologram shaping can be formed by a known method. For example, when recording diffraction gratings or interference fringes of holograms as reliefs of surface irregularities, a master on which the diffraction gratings or interference fringes are recorded in irregularities is pressed. The concave / convex pattern of the original can be duplicated by using it as a mold (referred to as a stamper) and by superimposing the original on the resin layer and heat-pressing both of them with an appropriate means such as a heating roll.

  Further, the hologram pattern formed on the hologram layer 15 may be single or plural. The hologram layer 15 is irradiated with ionizing radiation during or after embossing with a stamper to cure the ionizing radiation curable resin. The ionizing radiation curable resin becomes an ionizing radiation curable resin (fine irregularities = relief structure = hologram) when it is cured (reacted) by irradiation with ionizing radiation such as ultraviolet rays or electron beams after the relief is formed.

(Reflection layer) Since the reflection layer 17 is provided on the reflection layer 17 on the relief surface of the hologram layer 15 provided with a predetermined relief structure, the reflection reflection and / or diffraction effect is enhanced. If the rate is higher, it is not particularly limited. The reflective layer 17 may be a metallic glossy reflective layer such as a metal thin film by a vacuum thin film method or the like, or a transparent reflective layer, but the metallic glossy reflective layer is partially provided and the transparent reflective layer is formed on the transfer target. Even if the image is transferred to the surface of the image, it is preferable because the image can be observed. The transparent reflection layer has a substantially colorless and transparent hue, and its optical refractive index is different from that of the hologram layer. A hologram can be produced. For example, there are a thin film having a higher refractive index than the hologram layer 15 and a thin film having a lower refractive index. Examples of the former include ZnS, TiO ₂ , Al ₂ O ₃ , Sb ₂ S ₃ , SiO, SnO _2. ITO, etc., and examples of the latter include LiF, MgF ₂ , and AlF ₃ . Preferably, it is a metal oxide or nitride, specifically, Be, Mg, Ca, Cr, Mn, Cu, Ag, Al, Sn, In, Te, Fe, Co, Zn, Ge, Pb, Cd , Bi, Se, Ga, Rb, Sb, Pb, Ni, Sr, Ba, La, Ce, Au, and other oxides or nitrides, and the like can be exemplified by a mixture of two or more thereof. Also, a general light-reflective metal thin film such as aluminum can be used when it has a thickness of 200 mm or less. The transparent metal compound is formed on the relief surface of the hologram layer 15 by vacuum such as vapor deposition, sputtering, ion plating, and CVD so that the thickness of the relief layer of the hologram layer 15 is about 10 to 2000 nm, preferably 20 to 1000 nm. It may be provided by a thin film method or the like.

  (Receiving layer) A receiving layer 23 is provided on the surface of the transparent reflective layer 17 via a primer layer as necessary. The receiving layer 23 is the outermost surface of the patch intermediate transfer recording medium 20. An information printing layer 103 such as personal information is printed. As the printing method, for example, a thermal transfer system using a thermal transfer film of a melt transfer type or a sublimation type, or an ink jet system can be applied. The receiving layer 23 may be a known receiving resin layer corresponding to a printing method such as a thermal transfer method or an ink jet method.

Preferably, in the thermal transfer method using the thermal transfer ink ribbon of the melt transfer or sublimation type, the information residue remains on the used ink ribbon, but the ink-jet method that does not use the ink ribbon does not leave any trace of information and is excellent in security. An ink jet method is preferred.
As the receiving layer 23 used in the ink jet system, an ink jet receiving layer composition is applied, and the ink jet receiving layer composition contains at least a cationic urethane resin, a cationic fixing agent, a filler, and 2 molecules in the molecule. And aziridine derivatives having at least one aziridinyl group.

  Preferably, trimethylolmethane-tris- (β- (1-aziridinylpropionate)), trimethylolethane-tris- (β- (1-aziridinylpropionate)), trimethylolpropane-tris -(Β- (1-aziridinylpropionate)), trimethylolbutane-tris- (β- (1-aziridinylpropionate)), trimethylolethane-tris- (β- (2-methyl -1-aziridinylpropionate)), trimethylolpropane-tris- (β- (2-methyl-1-aziridinylpropionate)), trimethylolpropane-tris- (β- (2,2 -Dimethyl-1-aziridinylpropionate)), trimethylolpropane-tris- (α-methyl-β- (1-aziridinylpropionate), trimethylo Propane-tris- (β-methyl-β- (1-aziridinylpropionate), tetramethylolmethane-tris- (α-methyl-α-aziridinyl acetate), tetramethylolmethane-tris- (β- (1-aziridinylpropionate), tetramethylolethane-tris- (β- (1-aziridinylpropionate)), tetramethylolmethane-tris- (β- (2-propyl-1-aziridini) Lupropionate)), tetramethylolmethane-tris- (β- (2-methyl-1-aziridinylpropionate)), tetramethylolmethane-tris- (β- (2,2-dimethyl-1-) Aziridinylpropionate), tetramethylolmethane-tris- (β- (2,2-diethyl-1-aziridinylpropionate) tetramethylo Rumethane-tetrakis-β- (1-aziridinylpropionate), tetramethylolmethane-tetrakis-β-methyl-β- (1-aziridinylpropionate), tetramethylolmethane-tetrakis-β- (2 -Methyl-1-aziridinylpropionate), ditrimethylolpropane-hexakis- (β-aziridinylpropionate), ditrimethylolpropane-pentakis- (β- (2-methylaziridinylpropionate) Are preferred, trimethylolpropane-tris- (β- (1-aziridinylpropionate), tetramethylolmethane-tris- (β- (1-aziridinylpropionate), tetramethylolmethane-tetrakis- ( β-aziridinylpropionate).

  Examples of commercially available aziridine derivatives having two or more aziridinyl groups in the molecule include TAZM (trimethylolpropane-tris- (β-aziridinylpropionate), TAZO, manufactured by Mutual Yakuhin Co., Ltd.) (Tetramethylolmethane-tris- (β- (1-aziridinylpropionate))) Nippon Shokubai's Chemite PZ-33 (trimethylolpropane-tris- (β-aziridinylpropionate)) and the like An aziridine derivative having three aziridinyl groups is particularly preferred because of its high reactivity and a high network durability after curing.

  The ratio of cationic urethane resin, cationic fixing agent, microsilica, and aziridine derivative having two or more aziridinyl groups in the molecule is based on mass. Cationic urethane resin: Cationic fixing agent: Microsilica: Intramolecular The aziridine derivative having two or more aziridinyl groups in the group is 100: 5 to 20: 1 to 10: 1 to 15. If the content of the cationic fixing agent is less than the above range, the fixing property is poor, and if it exceeds the above range, it elutes during washing and lowers the fastness. If the content ratio of the microsilica is less than the above range, the ink fixing property is poor, and if it exceeds the above range, the transparency is lowered and the image becomes difficult to see.

Cationic urethane resin: Aziridine derivative having two or more aziridinyl groups in the molecule = 100: 1 to 15 is preferable, and 100: 3 to 10 is more preferable. Since the aziridine derivative functions as a water-soluble curing agent, if the content ratio of the aziridine derivative is less than the above range, since the curing is insufficient, durability such as water resistance and alcohol resistance is not sufficient, If it exceeds the above range, the transparency is lowered and the image becomes difficult to see.

  The receiving layer 23 is formed by dispersing or dissolving the above materials in a solvent, adding an additive as necessary, and providing a corona treatment or primer layer on at least one surface of the medium 101 as necessary. It may be applied and dried by a known coating method such as roll coating, gravure coating, comma coating or die coating. The thickness thereof is usually about 1 μm to 15 μm, preferably about 2 μm to 10 μm.

  (Peelable resin layer) The peelable resin layer 33 provided on the other surface of the transparent substrate 11 is formed of an adhesive layer, a simple adhesive layer, or an extrusion coating (EC) layer.

The pressure-sensitive adhesive layer is a conventionally known solvent-based or water-based pressure-sensitive adhesive, such as vinyl acetate resin, acrylic resin, vinyl acetate-acrylic copolymer, vinyl acetate-vinyl chloride copolymer, ethylene-vinyl acetate copolymer. Examples thereof include rubber resins such as coalescence, polyurethane resin, natural rubber, and chloroprene rubber. The coating amount of the pressure-sensitive adhesive layer is generally about 8 to 30 g / m ² (solid content), and is applied and dried by a conventionally known method such as gravure coating, roll coating, comma coating, and the like. To form an adhesive layer. Further, the adhesive strength of the pressure-sensitive adhesive layer is the peel strength between the transparent substrate 11 and the pressure-sensitive adhesive layer, and is desirably in the range of about 5 to 1,000 g in a 180 ° peeling method in accordance with JIS Z0237. It is preferable to select and use the kind of adhesive and the coating amount as described above so that the peel strength is within the above range when the adhesive layer is formed on the transparent substrate 11.

  For the simple adhesive layer, latex of acrylic resin such as styrene-butadiene copolymer rubber (SBR), acrylonitrile-butadiene copolymer rubber (NBR) or polyacrylate, rubber resin, waxes and a mixture thereof are used. Then, it may be formed on the surface of the transparent substrate 11 by a conventionally known coating method.

  Further, as the peelable resin layer 33, an EC layer may be provided on the surface of the transparent substrate 11. The thermoplastic resin forming the EC layer does not essentially adhere to the transparent substrate 11 and is not particularly limited as long as the resin has EC processing characteristics. On the other hand, a polyolefin-based resin having no essential adhesiveness and excellent workability is particularly preferable. Specifically, LDPE, MDPE, HDPE, PP resin, etc. can be used. Using a mat roll as the cooling roll for EC processing of these resins, the mat surface is transferred to the surface of the EC layer to make the irregular shape opaque, and the polyolefin resin is calcium carbonate, titanium oxide, etc. The white pigment may be kneaded and made opaque. The EC layer may be a single layer or a plurality of layers. The peel strength from the transparent substrate 11 can be adjusted by the processing temperature and the resin type during EC processing. When a plurality of layers are provided by the EC method, two layers of different resin types are used, and the peel strength can be easily adjusted by the difference in the resin types.

  (Other layers) The layers provided on the interlayer and / or the layer surface as needed include a primer layer, a printing layer, an antistatic layer, a back-sliding layer, etc., and each may be a known layer. In particular, the printing layer may be printed by a known screen printing or gravure printing method using colored ink or fluorescent ink.

  The support material preparation process of S2 is a process of preparing (2) the support base material 31 and the support material 30 provided with the laser marking layer 35 on one surface of the support base material 31.

  (Support Material / Support Base Material) The support material 30 is provided with a laser marking layer 35 on the support base material 31. The support substrate 31 is not particularly limited. For example, condenser paper, glassine paper, sulfuric acid paper, high-size paper, synthetic paper (polyolefin-based, polystyrene-based), fine paper, coated paper, synthetic resin, or emulsion Impregnated paper or polyester resins such as polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, polyamide resins, vinyl resins such as polyvinyl chloride, engineering resins such as acrylic resins, imide resins, polyarylate, polycarbonate Examples thereof include films such as cellulose-based films such as cyclic polyolefin resins and cellophane. When providing a laser marking layer 35 to be described later on the support substrate 31, the surface of the support substrate 31 may be subjected to a corona discharge treatment or a primer layer may be provided in order to improve adhesion.

  The support substrate 31 preferably has a thickness of 10 μm to 100 μm. If the support substrate is too thin, the patch intermediate transfer recording medium 20 obtained is free from so-called stiffness, and cannot be transported by a thermal transfer printer, or the patch intermediate transfer recording medium 20 Curls and wrinkles may occur. On the other hand, if the support base material 31 is too thick, the resulting patch intermediate transfer recording medium 20 becomes too thick, and the force to drive and drive the thermal transfer printer becomes so large that the thermal transfer printer fails or cannot be transported normally. Or

  (Laser Marking Layer) The laser marking layer 35 performs printing by irradiating laser light, and includes a binder resin and a color former that can be changed by laser irradiation. There are no particular limitations on color formers that can be changed by laser irradiation, but metals such as iron, zinc, tin, and nickel, copper carbonate, nickel carbonate, magnesium nitrate, iron nitrate, nickel nitrate, copper nitrate, magnesium acetate, and zinc acetate , Nickel acetate, copper acetate, copper chloride, iron chloride, nickel chloride, zinc chloride, copper phosphate, iron phosphate, copper pyrophosphate, copper sulfate, iron sulfate, cobalt sulfate, copper oxalate, iron oxalate, benzoic acid Metal salts such as copper and copper phosphonate having an aromatic ring, metal hydroxides such as copper hydroxide, aluminum hydroxide, magnesium hydroxide, zinc hydroxide, nickel hydroxide, iron hydroxide, silicon oxide, oxidation Aluminum, iron oxide, magnesium oxide, cobalt oxide, tin oxide, nickel oxide, copper oxide, ATO, ITO, synthetic zeolite, natural zeolite, copper hydroxide Inorganic acid copper hydrates such as phosphates, copper-molybten complex oxides (42-903A, manufactured by Tocan Material Technology Co., Ltd.), metal oxides such as mica, montmorillonite, smectite, etc. having a layered structure, Examples thereof include carbon black and known color formers and developers used for thermal recording. In addition, a copper-molybten complex oxide is preferable in that the blackness of characters and designs marked by laser irradiation and the nearby resin are easily blackened.

  The binder resin is not particularly limited, and examples thereof include acrylic resins, polyacetal resins, polyamide resins, polyester resins, polyvinyl chloride resins, polyolefin resins, polycarbonate resins, and polystyrene resins. Including the above binder resin and color former that can be changed by laser irradiation, and adding a dispersant, surface treatment agent, sensitizer for improving laser characteristics, color developer, and other additives as necessary. The laser marking layer 35 may be formed by printing by a known printing method such as gravure printing or screen printing and drying. The laser marking layer 35 can be drawn by solid printing on the whole or a part of the support base material 31 and irradiating the desired timing mark shape with laser light during use. The ratio of the color former capable of changing color by laser irradiation with respect to the binder resin in the laser marking layer 35 is 0.01 to 20%, preferably 0.1 to 10%. If it is less than this range, the laser color developability is inferior, and if it exceeds this range, the laser color developability is excessive, and since the binder resin content is small, the adhesion to the substrate and the cohesive strength of the film are inferior.

  (Heat resistant slipping layer) In the patch intermediate transfer recording medium 20, if necessary, a heat resistant slipping layer, an antistatic layer or the like may be provided on the surface opposite to the laser marking layer 35 surface of the support base 31. Since retransfer to the transfer target 101 using the patch intermediate transfer recording medium 20 is performed by a thermal transfer printer such as a thermal head or a heat roll, a heat resistant slipping layer is provided to prevent adverse effects such as sticking and wrinkles due to the heat. May be. The resin for forming the heat-resistant slipping layer may be any conventionally known resin such as polyvinyl butyral resin, polyvinyl acetoacetal resin, acrylic resin, cellulose resin, aromatic polyamide resin, polyimide resin, polycarbonate resin, etc. Is mentioned.

  The slipperiness-imparting agent that is added to or overcoated the heat-resistant slipping layer is, for example, a layer composed of a polyalcohol polymer compound, a polyisocyanate compound, and a phosphate ester compound, and a filler may be further added. preferable. The heat resistant slipping layer is prepared by dissolving or dispersing the above-described resin, slipperiness-imparting agent, and filler with an appropriate solvent, and, for example, gravure printing or screen printing on the back surface of the support substrate 31. It may be formed by applying and drying with the like.

  (Lamination process) The lamination process of S3 is a process of (3) laminating the laser marking layer surface of the support material and the peelable resin layer surface of the transfer material to form a laminate. The laser marking layer 35 surface of the support material 30 and the peelable resin layer 33 surface of the transfer material 10 may be formed by a known lamination method such as a dry lamination method using an adhesive or an adhesive 19 or a hot melt lamination method. . A dry lamination method using a urethane two-component adhesive is preferable.

  (Drawing process) The drawing process of S4 is a process of (4) drawing a timing mark with a laser beam on the laser marking layer of the laminate. A timing mark (a person skilled in the art also calls a register mark, a register mark, or a register mark) is drawn on the laser marking layer 35 with a laser beam.

  The type of laser for drawing the timing mark is not particularly limited, and examples thereof include a far infrared laser such as a carbon dioxide laser, a near infrared laser such as a YAG laser, a semiconductor laser, and an excimer laser, but an infrared laser is preferable. The type of marking is not particularly limited and may be any of a character, a symbol, a design, and the like. However, a rectangular shape and a linear shape are preferable in that a timing mark can be easily detected during use. The color tone and density of the timing mark drawn by the laser are not particularly limited as long as it can be detected by a sensor used at the time of use.

  (Half cut process) In the half cut process of S5, (5) the transfer part consisting of the transparent base material, the hologram layer, the transparent reflection layer and the receiving layer of the transfer material is subjected to a half cut process while being aligned with the timing mark. It is a process of applying and making a patch.

  Half-cut treatment methods include a method of inserting the patch intermediate transfer recording medium 20 in a stacked state before cutting between the upper die attached with the cutter blade and the pedestal, and moving the upper die up and down, or a cylinder type rotary There is no particular limitation as long as it is a method capable of half-cutting, such as a heat treatment method using a cutter method or laser processing means. It is not necessary to remove the patch 21 portion and the other portions, but as shown in the cross section of the patch intermediate transfer recording medium 20 shown in FIG. It is preferable to remove them (the person skilled in the art will refer to scrap removal). When the patch 21 is transferred to the transfer target, the transparent substrate 11 is not cut at the half-cut portion and can be transferred reliably.

  In general, half-cutting is performed by continuously cutting around the patch 21 in units of one round, and by partially providing uncut (no cut) parts such as four corners or perforated parts. It is possible to prevent troubles in which the half-cut portion is peeled off during handling such as transporting a thermal transfer printer. In addition, at least one part of the support material 30 is not cut and is made continuous. If the cutting depth is too deep in the half-cut processing, the support base material 31 is cut, and the printer is cut at the half-cut processing section during printer conveyance, which easily causes a conveyance trouble.

  (Patch Intermediate Transfer Recording Medium) The patch intermediate transfer recording medium 20 manufactured as described above has a patch intermediate transfer recording medium 20 as shown in FIG. Yes. The patch 21 is a patch in which a transfer portion of the transfer material 10 including the transparent base material 11 / the hologram layer 15 / the reflection layer 17 / the receiving layer 23 is subjected to a half cut process. Although it does not specifically limit as a shape of the patch 21, For example, a rectangle, an ellipse, a round shape, a donut shape etc. can be illustrated. The half-cut patch 21 portion may be smaller than the entire size of the transfer target body, and the patch 21 portion may be partially removed from the transfer body. Further, the entire width of the patch intermediate transfer recording medium 20 may be wider than the width of the surface to which the transfer target is transferred.

  (Anti-Counterfeit Medium) The patch 21 is detachably laminated on the surface of the support material 30 comprising the support base material 31 / laser marking layer 35 / adhesive layer 19 / peelable resin layer 33 / patch 21, and is transferred. Is peeled off from the surface of the transparent substrate 11 of the peelable resin layer 33 and the patch 21. After the information is printed on the surface of the receiving layer 23 of the patch 21 of the patch intermediate transfer recording medium 20, the patch 21 portion is transferred to the transfer body 101, and the forgery prevention medium 100 of the present invention as shown in FIG. 2 is obtained. .

  (Transfer method) As a transfer method for transferring to the transfer object 101, a known transfer method may be used, for example, hot stamping by hot stamping (foil stamping), transfer by a hot roll, thermal by a thermal head (thermal printing head). A known method such as a printer (also referred to as a thermal transfer printer) can be applied. Further, it may be transferred by heating in accordance with the shape of the patch 21.

  (Transfer To be Transferred) The transfer target 101 is not particularly limited, for example, natural fiber paper, coated paper, tracing paper, plastic film that is not deformed by heat during transfer, glass, metal, ceramics, wood, cloth, etc. Any one of them may be used, and it may be appropriately selected depending on the application. Further, at least a part of the medium of the transfer target 101 may be subjected to image, coloring, printing, or other decoration.

  (Printing) As a printing method of the information printing layer 103 such as personal information on the surface of the receiving layer 23, for example, a thermal transfer method using a thermal transfer film of a melt transfer type or a sublimation type or an ink jet method can be applied. The image on the receiving layer 23 is not particularly limited, but may be a spot shape such as a circle or a star, or an arbitrary shape such as a letter, a number, an illustration, or a photograph (a mirror image except for a symmetrical image), and its color tone is also independent. It is not limited to plural, full color and the like. The information printing layer 103 prints while aligning with the timing mark 37. Since the patch 21 is also aligned with the timing mark 37 and subjected to half-cut processing, an image that is the information printing layer 103 such as personal information that is different for each sheet can be printed at a predetermined position on the patch with high positional accuracy. In addition, when the patch 21 on which the image has been printed is transferred to the transfer target 101, the patch 21 is aligned by the timing mark 37, so that it can be transferred accurately and accurately.

  Since the conventional timing mark 37 is provided in advance on the support base 31 by gravure printing or the like, due to expansion and contraction due to heat or tension in the post-processing step, the interval accuracy of the timing mark 37 is reduced or the number of steps is high. It was a cost. The timing mark 37 according to the present invention is manufactured at a low cost and with high positional accuracy in order to form the timing mark 37 by irradiating the completed patch intermediate transfer recording medium 20 with laser light after the processing of the patch intermediate transfer recording medium 20 is completed. it can.

  (Inkjet) As a method for forming an image (information printing layer 103), a thermal transfer method using a melt transfer or sublimation type thermal transfer ink ribbon leaves an information residue on a used ink ribbon, but an inkjet method using no ink ribbon is used. This is preferable in that no trace of information remains and security is excellent. The ink jet method includes a thermal impact method, but is not particularly limited. The ink jet ink includes water-based and oil-based inks, but is not particularly limited. A preferable receiving layer 23 for printing the information printing layer 103 by the ink jet method includes a cationic urethane resin, a cationic fixing agent, a filler, and an aziridine derivative having two or more aziridinyl groups in the molecule. . Since it contains a cationic urethane-based resin, a cationic fixing agent, and a filler, even if printing is performed by an ink jet method, the image does not blur and drying is fast, so printing can be performed efficiently. In addition, since it contains an aziridine derivative having two or more aziridinyl groups in the molecule, even an information image printed by an ink jet method has high image quality and good fixability, and the printed image is scratch resistant. , Solvent resistance such as water resistance and alcohol resistance, and durability such as fastness to washing.

  (Image) Further, the image of the information printing layer 103 formed by the ink jet method is not limited to any shape and color tone. Preferably, different information can be printed one by one by printing variable information on an on-demand basis using an inkjet method.

  (Fixability) As an image by a conventional ink jet method, when creating an ID card such as an ID card, it is easy to form an image. However, these images have a drawback that they are inferior in durability, particularly in abrasion resistance. is there. Conventional ink-receiving layers are mainly composed of water-soluble resins such as polyvinyl alcohol, and the water resistance is remarkably poor. Also, porous fillers are used, and good and poor solvents are used as the solvent for the receiving layer coating solution. Although a solvent is used to separate the phases and gel during drying to form a porous network structure, there is a problem that the image is not sufficiently fixed and the image becomes light during washing.

  On the other hand, the preferable receiving layer 23 also contains an aziridine derivative having two or more aziridinyl groups in the molecule, and even the image 103 printed by the inkjet method has high image quality and good fixability. The printed image is excellent in scratch resistance, solvent resistance such as water resistance and alcohol resistance, and durability such as fastness to washing. Although coexistence of fixing property and fastness to washing is not certain, by including a cationic urethane resin, a cationic fixing agent, a filler, and an aziridine derivative having two or more aziridinyl groups in the molecule, The surface has fine irregularities, the coating itself is not dense and is rather rough, and an aziridine derivative having two or more aziridinyl groups in the molecule reacts with other components. As a result, the network and the aggregated state are stabilized, so that the adhesion with the image components is improved, and in particular, the alcohol resistance can be improved. In addition, it is presumed that a dye constituting an image interacts with or reacts with a cationic urethane resin, a cationic fixing agent, an aziridine derivative having two or more aziridinyl groups in the molecule and curing.

  (Durability of Image) The information printing layer 103 is sandwiched between the transfer material 10 and the transfer target 101, but the cross section is exposed and water resistance by water immersion from the cross section is excellent. For example, a vinyl chloride credit card (inkjet image recording medium) having the receiving layer 23 of the patch intermediate transfer recording medium 20 of the present invention passes the chemical immersion resistance of the card in accordance with JIS X6301, specifically, This will be described in Examples. That is, even in an exposure test for 240 hours in an atmosphere at 80 ° C., it has heat resistance without peeling from the interlayer and / or the adherend. Even in a 96-hour immersion test in hot water at 40 ° C., it has hot water resistance without peeling from the interlayer and / or the adherend. It has friction resistance that does not cause significant scratches in 100 wiping tests at room temperature while applying pressure at 20 kPa using a sheet cleaner. The conditions of low temperature (−40 ° C.), high temperature (80 ° C.) and high humidity (40 ° C. and 90% RH) are set to 1 cycle (1 day) every 8 hours, and even in a 5 cycle (5 days) thermal cycle test, It has cold and heat resistance without peeling.

  (Printing and Transfer) If the information printing layer 103 to be an image is printed on the receiving layer 23 of the patch intermediate transfer recording medium 20 by an ink jet printer or the like, and the patch 21 including the information printing layer 103 is transferred, the forgery prevention medium 100 It becomes. It is preferable to transfer the patch 21 including the information printing layer 103 by in-line method in the same printer following printing by an inkjet printer or the like, and printing and transfer are performed once while being aligned with the timing mark 37. Therefore, the positional accuracy of the information printing layer 103 and the positional accuracy of transfer to the transfer target 101 are extremely good and efficient.

  (Durability) In this way, the anti-counterfeit medium 100 using the patch intermediate transfer recording medium 20 forms a highly durable patch (the transparent base material 11 serves as a protective layer) on the information printing layer 103. Excellent durability for various types of thermal transfer images even under harsh use conditions. Patches can be easily transferred to the transfer target 101. The transferred medium has a hologram with excellent security and is in use. It has durability and is excellent in scratch resistance and solvent resistance that protects the surface of the medium even after repeated use. Protects the surface of the medium even after repeated use and protects it from mechanical and chemical damage over a long period of time, so there is no gas station card or construction site card used in extremely harsh environments and no expiration date It can also be suitably used for long-term entrance / exit cards, point cards, and entrance / exit cards that repeatedly enter and exit a number of security-controlled rooms such as financial institutions.

The laminate was left to stand.
(S4) Using a machine having a laser marker part, a punching part, and a half-cut part, the laminate is intermittently run, and a laser beam is applied to the laser marking layer 35 using a YAG laser “MD-H9800 manufactured by Keyence Corporation”. A rectangular timing mark 37 of 5 mm × 20 mm was drawn. The timing mark 37 did not swell or peel off, was black, had good visibility, and had a color density that could be sufficiently read by a suncer.
(S5) Subsequent to the timing mark 37, a 15 mm × 20 mm hole is punched in the shoulder portion of the patch 21 at the punching portion of the upper die and the lower die attached with a rectangular cutter blade. The hologram layer 15 / transparent reflection layer 17 / primer layer / receiving layer 23 of the laminate is a half-cut portion that can perform half-cut processing and waste removal of the upper die and pedestal to which a round rectangular cutter blade is attached. The layer-constituting portion is 54 mm × 85 mm in a rounded round shape (becomes the patch 21), half-cut, removed, and the patch 21 is laminated in a peelable manner from the surface of the peelable resin layer 33.

  (Evaluation) The image that is the information printing layer 103 in the ink jet method such as personal information that differs for each sheet can be printed with high positional accuracy and normally with respect to the patch 21, The patch 21 was also transferred to the transfer target 101 accurately and with high positional accuracy. As described above, the timing mark 37 is provided on the patch intermediate transfer recording medium 20 that has already finished the influence of expansion and contraction due to heat and tension in the processing process, and the layer configuration is completed. Since all of the information printing layer 103 is aligned, the positional accuracy of each is very good. Moreover, although 50 cards were operated continuously, all the positional accuracy was very stable. In addition, since the conventional timing mark 37 is previously provided on the support base 31 by gravure printing or the like, the interval accuracy of the timing mark 37 is reduced due to expansion or contraction due to heat or tension in the post-processing step, Many were expensive. The timing mark 37 according to the present invention is used in the post-processing step in order to form the timing mark 37 by irradiating the finished patch intermediate transfer recording medium 20 with a laser beam after the processing of the patch intermediate transfer recording medium 20 is completed.

Images were visually observed after being immersed in 5% saline, 5% acetic acid, 5% aqueous sodium carbonate solution, 10% sugar water, 50% ethylene glycol, and 60% ethanol for 24 hours. In the evaluation, “◎” indicates that almost no change is observed in the image 103, “○” indicates that no significant change is observed and that it is acceptable for practical use, and “×” indicates that the image 103 is distorted, missing, or lost. And rejected it. All of the anti-counterfeit media 100 of Example 2 were “」 ”and satisfied the credit card standard.
