  (Main applications) The method of manufacturing the patch transfer medium of the present invention, and the main applications of the patch transfer fibrous material (medium) obtained by transferring a patch using the patch transfer medium include, for example, clothing such as T-shirts, Carton, case, packaging materials such as exterior paper, accessories such as bags, appreciation tickets, greeting cards, envelopes, tags, bookmarks, calendars, posters, brochures, nameplates, report paper and other stationery, building materials, panels, emblems , Footwear, shoes, etc. However, after transfer, the protective layer becomes the outermost surface, and it is transferred by heating and pressing a patch with a hologram that has durability, especially toughness, excellent scratch resistance due to sharp objects, and excellent design, with an iron or the like If it is a use to do, it will not specifically limit.

(Background Art) In recent years, personal preferences have been diversified and personalized, and many personal products have a tendency to produce a variety of small lots. For stationery and apparel products, there is a demand for only one product per person. However, traditional fabric materials such as cloth and paper, such as decoration on T-shirts, can be directly screen-printed, or transferred to T-shirts after printing on transfer paper by offset or screen printing. After transfer, there is a problem that the decoration becomes the outermost surface and is inferior in durability.
In addition, a protective layer thermal transfer film having a thermal transfer resin layer is superimposed on the decorative surface, and the transparent thermal transfer resin layer is transferred using an iron or a heating roll to form a protective layer on the decoration. Has been done. However, since the above protective layer needs to be partially transferred at the time of transfer by an iron or a heat roll, it needs to have a foil cutting property. In this case, since the protective layer has to be a resin film having a thickness of about several microns, there is a disadvantage that durability such as tough scratch resistance and chemical resistance cannot be provided.
Furthermore, there are types that transfer together with PET or OPP film, but the film has a problem that it is inferior in scratch resistance due to a sharp object and is easily damaged.
Therefore, the decoration method to fabric materials such as cloth and paper can be easily manufactured (transferred) at low cost by heating and pressing a patch having a hologram with excellent designability with an iron etc., and after transfer There is a need for patch transfer media and patch transfer fiber materials that are durable on the outermost surface, particularly tough and excellent in scratch resistance due to sharp objects.

(Prior Art) Conventionally, the present applicant has known a hologram transfer foil provided with a base material, a peelable resin layer, a hologram layer also serving as a hard coat function, a reflective layer, and an adhesive layer (for example, Patent Document 1). reference.). However, it is a partial transfer at the time of transfer, and in order to improve the foil cutting property, the hologram layer must be a resin film with a thickness of about several microns, and is transferred to the surface of the medium to become the outermost surface. When used repeatedly, there is a drawback in that it lacks durability such as scratch resistance and solvent resistance.
In addition, the applicant has laminated a sheet base material provided with a resin layer and a transparent sheet provided with a hologram forming layer and a receiving layer, and the transparent sheet portion including the hologram forming layer and the receiving layer is subjected to a half cut process. An intermediate transfer recording medium that peels between a resin layer and a transparent sheet is disclosed (for example, see Patent Documents 2 to 3). However, the receiving layer is essential, and the image is printed on the receiving layer and retransferred, and there is no mention of imparting durability such as scratch resistance and solvent resistance of the image printed on the medium.

And a half-cut treatment process.

  (Step 1) Step 1S1 prepares (1) a transparent base material 11 and a transfer material 10 provided with a hologram layer 15 and a reflective layer 17 on one surface of the transparent base material 11. As shown in FIG. 2, the transfer material 10 includes a transparent base material 11 and a hologram layer 15 and a reflective layer 17 on one surface of the transparent base material 11.

  (Transparent substrate) The transparent substrate 11 is composed of a protective layer 14, an adhesive layer 29, a transparent substrate 11, a hologram layer 15, a reflective layer 17, and an adhesive layer 19 with a half-cut treated portion as a boundary. The structure is cut as a part of the transfer part 23, and transferred to the fibrous base material 101 as a transfer target, and exhibits a protective function together with the protective layer 14. Various materials can be applied depending on the application as long as they have transparency and durability such as 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 preferably (1) an isocyanate having three or more isocyanate groups in the molecule, and (2) at least one hydroxyl group and at least two (meth) acryloyloxy groups in the molecule. Preferably using an ionizing radiation curable resin containing a polyfunctional (meth) acrylate having, or (3) a urethane (meth) acrylate oligomer which is a reaction product of a polyhydric alcohol having at least two hydroxyl groups in the molecule. May contain polyethylene wax, applied, dried, and cured with ionizing radiation to form an ionizing radiation curable resin.

  The ionizing radiation curable resin containing the urethane (meth) acrylate oligomer (referred to herein as the ionizing radiation curable resin composition M) is a cured ionizing radiation curable resin containing the urethane (meth) acrylate oligomer. Examples thereof include photocurable resins disclosed in Japanese Patent Application Laid-Open No. 2001-329031. 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 with the above-mentioned ionizing radiation curable resin as a main component, and silicone, filler, photopolymerization initiator, plasticizer, stabilizer, surfactant, etc. are added as necessary. , Dispersed or dissolved in a solvent, applied by a known coating method such as roll coating, gravure coating, comma coating, die coating, etc., dried and reacted (cured) with ionizing radiation after shaping the hologram (relief) Good. The thickness of the hologram layer 15 is usually about 1 to 10 μm, preferably 2 to 5 μm.

  (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, such as 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 it 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.

  (Step 2) Step 2S2 prepares (2) a support base material 31 and a support material 30 provided with a peelable resin layer 33 on one surface of the support base material 31. As shown in FIG. 3, the support material 30 is provided with a peelable resin layer 33 on a support base material 31.

  (Supporting base material) The supporting base material 31 is not particularly limited. For example, condenser paper, glassine paper, sulfuric acid paper, high-size paper, synthetic paper (polyolefin-based, polystyrene-based), high-quality paper, coated paper , Synthetic resin or emulsion-impregnated paper, polyester resins such as polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, polyamide resins, vinyl resins such as polyvinyl chloride, acrylic resins, imide resins, polyarylate, etc. Examples include engineering resins, polycarbonates, cyclic polyolefin resins, and cellulose films such as cellophane. When the peelable resin layer 33 described later is provided on the support base 31, the surface of the support base 31 may be subjected to corona discharge treatment or a primer layer may be provided in order to improve adhesion.

  The support material 30 preferably has a thickness of 10 μm to 100 μm. If the sheet base material is too thin, the so-called stiffness of the obtained patch transfer medium 20 is lost, and it cannot be conveyed by a thermal transfer printer, or the patch transfer medium 20 is curled or wrinkled. Occur. On the other hand, if the support material 30 is too thick, the resulting patch transfer medium 20 becomes too thick, and the force to drive and drive the thermal transfer printer becomes too great, causing the thermal transfer printer to fail or not be transported normally.

(Peelable resin layer) The peelable resin layer 33 is formed of a pressure-sensitive 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 support substrate 31. Moreover, in order to provide an adhesive layer on the support base material 31 and to laminate the transparent base material 11 and the adhesive layer, methods such as dry lamination and hot melt lamination of the adhesive layer can be employed.

  The simple adhesive layer uses styrene-butadiene copolymer rubber (SBR), acrylonitrile-butadiene copolymer rubber (NBR), latex of acrylic resins such as polyacrylic acid esters, rubber resins, waxes and mixtures thereof. Then, it may be formed on the support substrate 31 by a conventionally known coating method, and the transparent substrate 11 and the simple adhesive layer may be laminated by dry lamination while heating. And the simple adhesive layer after peeling the transparent base material 11 and the support base material 31 falls in adhesiveness, and the transparent base material 11 and the support base material 31 cannot be bonded together again. When such a simple adhesive layer is used, a primer layer may be provided between the support base 31 and the simple adhesive layer.

  Further, as the peelable resin layer 33, an EC layer may be provided on the support base 31. 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 a 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. In this way, the EC layer is formed on the support substrate 31 simultaneously with EC processing, and the support substrate 31 and the transparent substrate 11 may be laminated via the EC layer by so-called EC lamination.

  (Heat resistant slipping layer) In the patch transfer medium 20, a heat resistant slipping layer may be provided on the surface opposite to the peelable resin layer 33 surface of the support base 31 as required. Since retransfer to the transfer target 101 using the patch transfer medium 20 is performed by a thermal transfer printer such as a thermal head or a heat roll, a heat resistant slipping layer may be provided to prevent adverse effects such as sticking and wrinkles due to the heat. Good. 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.

  (Step 3) In step 3S3, (3) a protective layer 14 including a crosslinked polyester resin obtained by crosslinking a saturated copolymerized polyester resin with an isocyanate compound and a filler is provided on the surface of the peelable resin layer 33 of the support material 30, and FIG. It becomes the structure shown in.

  (Protective layer) The protective layer 14 includes a crosslinked polyester resin obtained by crosslinking a saturated copolymerized polyester resin with an isocyanate compound and a filler. The saturated copolyester resin has a hydroxyl group at the terminal, and examples thereof include commercially available Elitel UE3410 and UE-3510 manufactured by Unitika. Examples of the isocyanate compound include isocyanate compounds containing two or more isocyanate groups and urethane resins such as commercially available Coronate L and Coronate HL manufactured by Nippon Polyurethane, Takenate D103H and Takenate D165N manufactured by Mitsui Polyurethane. What is necessary is just to bridge | crosslink said saturated copolyester resin with said isocyanate compound as a crosslinked polyester resin.

  (Formation of protective layer) The protective layer 14 is a well-known roll coat, gravure coat, comma coat, etc. by dispersing or dissolving a saturated copolymerized polyester resin, an isocyanate compound, a filler, and, if necessary, an additive in a solvent. In this coating method, after coating and drying, it is cured (reacted) in a greenhouse to form the protective layer 14. The protective layer 14 becomes the outermost surface after transfer, and is excellent in durability, particularly tough and scratch resistance due to a sharp object. The thickness of the protective layer 14 is usually about 1 μm to 30 μm, preferably about 2 μm to 20 μm. It may be applied several times.

  Examples of the filler include micro silica and polyethylene wax. Preferably, the blending ratio of the filler to the crosslinked polyester resin is based on mass, and the crosslinked polyester resin: filler = 100: 5 to 20. Below this range, the scratch resistance is insufficient, and beyond this range, the transparency is lowered.

  (Step 4) In step 4S4, (4) the surface of the protective layer 14 and the surface of the transparent substrate 11 of the transfer material 10 are laminated through an adhesive layer 29 to form a laminate 50, as shown in FIG. It becomes the composition.

  (Lamination process) The surface of the protective layer 14 provided on the surface of the release resin layer 33 of the support material 30 and the surface of the reflective layer 17 of the transfer material 10 are dry laminated using an adhesive or an adhesive 19 or hot melt. A known lamination method such as a lamination method may be used. A dry lamination method using a urethane two-component adhesive is preferable.

  (Step 5) In step 5S5, (5) the adhesive layer 19 made of hot melt is provided on the surface of the reflective layer 17 of the laminate 50.

  (Adhesive layer) The adhesive layer 19 is not particularly limited as long as it is a heat-sensitive or pressure-sensitive adhesive that does not have adhesiveness at normal temperature or normal pressure, and exhibits adhesive force only when heated or pressurized. A resin having a relatively low melting point such as a vinyl resin, a vinyl chloride-vinyl acetate copolymer resin, or a polyester resin is preferred. The resin as described above may be melted by heat to form a liquid, which may be applied and cooled by roll coating, comma coating, or hot malt applicator method. Since the material to be transferred permeates through the porous fibrous base material 101, the thickness is preferably 30 to 150 μm. Further, the adhesive layer 19 may contain a white pigment, an extender pigment, and a fluorescent brightening agent, which can improve the whiteness after transfer or conceal the color of the fibrous base material 101.

  (Step 6) Step 6S6 is (6) a configuration including the protective layer 14, adhesive layer 29, transparent base material 11, hologram layer 15, reflection layer 17 and adhesive layer 19 as a transfer portion 23. A half-cut treatment is performed to form a patch 21, and the patch is laminated so as to be peelable on the surface of the peelable resin layer 33 of the support material 30.

  (Half-cut process) As a half-cut treatment method, a method of moving the upper die up and down by inserting the patch intermediate transfer recording medium 20 in a stacked state before cutting between the upper die attached with a cutter blade and the pedestal, There is no particular limitation as long as the method can be half-cut, such as a cylinder-type rotary cutter method or a heat treatment method using a 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.

  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. Furthermore, the entire width of the patch transfer medium 20 may be wider than the width of the surface to which the transfer target is transferred.

  (Patch Transfer Medium) The transfer portion 23 of the patch transfer medium 20 is half-cut into a patch 21 and is detachably laminated on the surface of the peelable resin layer 33 of the support material 30.
