However, after the transfer, the release layer having a hard coat function becomes the outermost surface, and the transfer is easy by heating and pressing a patch having a hologram and a printing layer having excellent scratch resistance and excellent design properties with an iron or the like. It is not particularly limited as long as it can be used.

(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 unique products. 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, it is a decoration on fabric materials such as cloth and paper, and after heating and pressurizing a patch having a hologram and printing layer with excellent design properties with an iron or the like, the support substrate and the release layer are peeled off and removed. By peeling between the release layer and the release layer, the patch is transferred to the transfer object, and the outermost surface becomes the release layer, so that the scratch resistance is excellent and the design There is a need for a patch transfer medium having a hologram with excellent properties, a method for manufacturing the patch transfer medium, and a patch transfer fibrous material.

(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 transparent reflection layer, and an adhesive layer (for example, patent documents). 1). 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 tough scratch resistance and solvent resistance.
Also known is a water-repellent thermal transfer sheet, which is a thermal transfer sheet that is transferred to a surface of a T-shirt or the like by pressing it with a heated iron, and is configured so that the color toner image of the transfer sheet transferred to the T-shirt or the like does not surface. (For example, see Patent Document 2). However, there is a drawback that it lacks durability such as tough scratch resistance and solvent resistance.

  (Image Forming Method) Next, the method for producing the patch transfer medium of the present invention will be described. As shown in FIG. 1, the method for producing a patch transfer medium of the present invention includes (1) a transparent substrate 11 in step 1S1, and a hologram layer 15, a transparent reflective layer 17 and printing on one surface of the transparent substrate 11. A transfer material preparation step for preparing the transfer material 10 provided with the layer 18, a support material preparation step for preparing the support material 30 composed of (2) the support base material 31 in step 2S2, and (3) the transfer in step 3S3. A release layer and release layer forming step in which a release layer 14 and a release layer 13 are provided on the surface of the material 10 opposite to the hologram layer 15 of the transparent substrate 11, and (4) the release layer 13 surface in step 4S4 The step of laminating the support base material 31 surface of the support material 30 via the adhesive layer 29 to form the laminate 50, and in step 5S5 (5) to the print layer 18 surface of the laminate 50, An adhesive layer 19 made of hot melt is provided. (6) Step 6S6 (6) The structure comprising the release layer 14, the transparent substrate 11, the hologram layer 15, the transparent reflective layer 17, the print layer 18 and the adhesive layer 19 is used as the transfer section 23, and the transfer The portion 23 is subjected to a half-cut process to form a patch 21, and the patch 21 includes a half-cut process step in which the patch 21 is detachably laminated on the surface of the release layer 13.

  (Step 1) Step 1S1 is (1) a transfer in which a transparent base material 11 and a transfer material 10 comprising a hologram layer 15, a transparent reflection layer 17 and a printing layer 18 on one surface of the transparent base material 11 are prepared. This is a material preparation process. The transfer material 10 is configured as shown in FIG.

  (Transparent substrate) The transparent substrate 11 is composed of a release layer 14, a transparent substrate 11, a hologram layer 15, a transparent reflective layer 17, a printed layer 17, and an adhesive layer 19, with a half-cut processed portion as a boundary. The structure is cut as a part of the transfer portion 23 to form a patch 21, which is transferred to the fibrous base material 101 that is a transfer target, and exhibits a protective function together with the release 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.

(Transparent Reflective Layer) Since the transparent reflective layer 17 is provided on the transparent reflective layer 17 on the relief surface of the hologram layer 15 provided with a predetermined relief structure, the reflection and / or diffraction effect of the relief is enhanced. There is no particular limitation as long as the reflectance is higher or lower than 15. The transparent reflective layer 17 is a transparent reflective layer formed by a vacuum thin film method or the like. 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.

  (Print layer) The print layer 18 is not particularly limited, and may be printed by a known printing method such as gravure printing, screen printing or flexographic printing. The color of the printed pattern is not particularly limited, and may be any of color, single color, multicolor, and matal, and the image pattern is not particularly limited, and may be any of letters, symbols, numbers, illustrations, photographs, and the like. Since the design is transferred and observed from the surface of the base material 11, it may be printed so that it can be normally observed. If this is used and transferred to, for example, a T-shirt, a T-shirt having a hologram and a pattern according to preference can be obtained.

  (Step 2) Step 2S2 is (2) a support material preparation step for preparing a support material 30 comprising the support base material 31. The support member 30 is configured as shown in FIG.

  (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.

  The support base material 31 to be the support material 30 is preferably 10 μm to 100 μm in thickness. 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. 20 may be curled or wrinkled. 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.

(Heat resistant slipping layer) In the patch transfer medium 20, if necessary, other layers such as a heat resistant slipping layer and an antistatic layer may be provided on the surface opposite to the adhesive layer 29 surface of the support substrate 31, At that time, a primer layer may be interposed.
Since the thermal transfer printer such as a thermal head or a heat roll is used for transferring to the fibrous base material 101 using the patch transfer medium 20, a heat resistant slipping layer is provided in order to prevent adverse effects such as sticking and wrinkles due to the heat. preferable. 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) Step 3S3 is (3) a release layer and release layer forming step in which the release layer 14 and the release layer 13 are provided on the surface of the transfer material 10 opposite to the hologram layer 15 of the transparent substrate 11; The configuration is as shown in FIG.

  (Peeling layer) As the peeling layer 14, a release resin such as a fluorine resin, silicone, melamine resin, epoxy resin, polyester resin, acrylic resin, and fiber resin, a resin containing a release agent, A curable resin that crosslinks with ionizing radiation is used. In the present invention, an acrylic resin and polyethylene wax are the main components. Examples of acrylic resins include methacrylate resins such as polymethyl methacrylate, polyethyl methacrylate, and butyl polymethacrylate, and polymethacrylate resin such as methyl methacrylate resin (polymethyl methacrylate). preferable.

  (Polyethylene wax) Polyethylene wax includes polyethylene resin particles and beads, and is preferably spherical beads. The size of the particles is preferably equal to or larger than the thickness of the release layer 14 and is preferably exposed to the surface of the release layer 14 in terms of scratch resistance. The addition amount is acrylic resin: polyethylene wax = 100 parts by mass: about 0.01 to 10 parts by mass, preferably 0.1 to 5 parts by mass. Below this range, the scratch resistance is inferior, and beyond this range, the transparency deteriorates.

  (Formation of release layer) The release layer 14 is mainly composed of a methacrylate resin and polyethylene wax, and if necessary, an additive is dispersed or dissolved in a solvent so as to be known as roll coat, gravure coat, comma coat, etc. The coating layer is applied and dried to form a release layer 14. The thickness of the release layer 14 is usually about 1 μm to 30 μm, preferably about 3 μm to 10 μm. It may be applied several times.

  (Release layer) The release layer 13 is mainly composed of an acrylate resin, and the acrylate resin is preferably a polyacrylic ester resin such as polymethyl acrylate or polybutyl acrylate.

  (Formation of Release Layer) The release layer 13 is composed of a polyacrylate resin as a main component, and an additive is dispersed or dissolved in a solvent as necessary, so that a roll coat, a gravure coat, a comma coat, etc. are known. The coating layer is applied and dried to form the release layer 13. The thickness of the release layer 13 is usually about 0.1 μm to 20 μm, preferably about 1 μm to 10 μm. It may be applied several times. The thinner the thickness is, the better. However, when the thickness is 0.1 μm or more, better film formation is obtained and the peeling force is stabilized.

  (Release layer and release layer) That is, the release layer 13 mainly composed of an acrylate resin and the release layer 14 mainly composed of a methacrylate resin and polyethylene wax are combined and peeled when transferring. Two layers are used at the interface. For this reason, when the patch 21 is transferred to the transfer target 101, it can be easily and stably peeled between the release layer 13 and the release layer 14, and the transfer target (fibrous substrate) 101). In the conventional one-layer structure of the release layer or release layer, the release layer or the release layer is peeled from another layer in contact with the release layer or release layer. However, the other layers are responsible for their functions and will peel off, but since the functions of the layers are emphasized, the peeling force control of the peeling is secondary and difficult to control, and the peeling stability The nature is also low. These disadvantages can be eliminated by combining the release layer 13 and the release layer 14 of the present invention. That is, after the patch 21 is heated and pressed with an iron or the like, the support base 31 and the release layer 13 are peeled and removed, so that the release layer 13 and the release layer 14 are peeled off, The patch 21 can be easily and stably transferred to the transfer target (fibrous substrate 101).

  (Step 4) Step 4S4 is (4) a lamination step in which the release layer 13 surface and the transparent base material 11 surface of the support material 31 are laminated via the adhesive layer 29 to form a laminate 50, The configuration is as shown in FIG.

  (Lamination process) The surface of the support substrate 31 of the support material 30 and the surface of the release layer 13 provided on the transfer material 10 are dry-laminated via a pressure-sensitive adhesive or adhesive 19, or hot melt lamination is used. The known laminating method may be used. A dry lamination method using a urethane two-component adhesive is preferable.

  (Step 5) Step 5S5 is (5) an adhesive layer forming step in which an adhesive layer 19 made of hot melt is provided on the surface of the printed layer 18 of the laminate 50, and has a configuration as shown in FIG.

  (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) the transfer part 23 is composed of the release layer 14, the transparent substrate 11, the hologram layer 15, the transparent reflection layer 17, the print layer 18 and the adhesive layer 19, and the transfer part 23 is This is a half-cut processing step in which a half-cut process is performed to form a patch 21, and the patch 21 is detachably laminated on the surface of the release layer 13. The patch has the configuration shown in FIG. It becomes the transfer medium 20.

  (Half-cut process) As a half-cut treatment method, a method of moving the upper die up and down by inserting the patch transfer medium 20 in a stacked state before cutting between the upper die attached with a cutter blade and the pedestal, or a cylinder There is no particular limitation as long as it is a method capable of half-cutting, such as a type of rotary cutter method or a heat treatment method using laser processing means. It is not necessary to remove the patch 21 portion and other portions, but as shown in the cross section of the patch transfer medium 20 shown in FIG. It is preferable to keep it (referring to those skilled in the art as 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.
