An intermediate transfer medium or the like provided so as to be removable from the base material is used. In the former case, a printed matter can be produced by forming a thermal transfer image on the receiving layer of the thermal transfer image receiving sheet using a thermal transfer sheet provided with a color material layer. Further, by using a protective layer transfer sheet provided with a transferable transparent protective layer on a base material and transferring the protective layer onto a photographic paper on which a thermal transfer image is formed, the durability of the thermal transfer image is improved. Can be improved. In the latter case, a thermal transfer sheet provided with a color material layer is used to once form a thermal transfer image on the receiving layer of the intermediate transfer medium, and then the transfer layer containing the receiving layer is used as a predetermined transfer target. By transferring, it is possible to produce a printed matter in which a thermal transfer image is formed on the transferred body.

When an intermediate transfer medium is used, the protective layer is transferred at the same time as the thermal transfer image is formed, so that a certain degree of abrasion resistance, chemical resistance, or weather resistance can be obtained. However, for some ID cards, credit cards, etc., further improvement in durability may be desired, and in such a case, in addition to the process of forming a heat transfer image on the card face using an intermediate transfer medium. , It was necessary to form an additional protective layer while aligning with the card and the heat transfer image formed on the card in a separate process. For this reason, there is a problem that the process becomes complicated, the lead time becomes long, and the yield and quality deteriorate due to the misalignment of the protective layer formed on the card.

On the other hand, in Patent Document 1, a detection mark is put on the heat transferable protective layer and the like, and the resin layer and the heat transfer are made in the intermediate transfer medium in which the base sheet, the resin layer, the heat transferable protective layer and the receiving layer are laminated in this order. A protective layer-integrated intermediate transfer medium is described in which the sex protective layer is half-cut to form a patch portion. In this case, the thermal transfer image formation and the protective layer formation can be continuously performed by aligning the detection marks at the time of forming the thermal transfer image to the receiving layer and at the time of transferring the patch portion to the transfer target.

Further, Patent Document 2 describes an image forming method in which a transparent sheet and a receiving layer are half-cut and a patch portion is provided in an intermediate transfer medium in which a sheet base material, a resin layer, a transparent sheet, and a receiving layer are laminated in this order. Is described. According to this method, a heat transfer image is formed in a region of a receiving layer having a size equal to or larger than that of the patch portion, the receiving layer and the transparent sheet around the patch portion are removed, and then only the patch portion is transferred to the transferred body. Can be transferred.

For ID cards and credit cards, it is required to form an image on the entire face of the card as much as possible to reduce the margin at the outer edge, and to appropriately protect the image by forming a protective layer or the like. Furthermore, there is a need for a method for producing a photographic paper that can be carried out by a simple method without going through a complicated process or high-precision control, and an intermediate transfer medium used for the method.

It is a plan view. 2A and 2B are views for explaining the thermal transfer sheet 200, FIG. 2A is a cross-sectional view, and FIG. 2B is a plan view seen from a direction perpendicular to the main surface. Further, FIG. 3 is a plan view showing the intermediate transfer medium 100 in which the notch 310 and the detection mark 710 are formed. Hereinafter, each step related to the configuration of the intermediate transfer medium 100 and the thermal transfer sheet 200 and the method for producing a printed matter will be described.

(A) Intermediate transfer medium As shown in FIG. 1 (a), the intermediate transfer medium 100 includes a laminated structure of a release member 110 and a transfer sheet 120. The release member 110 has a structure in which the back surface layer 90, the support 80, and the adhesive layer 70 are laminated in this order along the direction from the release member 110 to the transfer sheet 120. Further, the transfer sheet 120 has a structure in which the release layer 60, the protective sheet 50, and the transfer layer 40 are laminated in this order. Further, the transfer layer 40 is a stack of the release layer 30, the protective layer 20, and the receiving layer 10 in this order.

A predetermined pattern of a thermal transfer image 400 is formed on the receiving layer 10 which is the exposed outermost surface of the transfer layer 40. Further, the intermediate transfer medium 100 is formed with a half-cut notch 310 penetrating the thickness direction of the transfer sheet 120, excluding the release member 110. Further, as shown in FIG. 1B, the notch 310 is formed in the shape of a substantially quadrangle with rounded corners when viewed in a plan view, whereas the thermal transfer image 400 is a substantially quadrangle formed by the outline of the notch 310. It is also formed outside the area. Although not shown, for convenience of explanation, the intermediate transfer medium before the notch processing is formed is referred to as an intermediate transfer medium 100a, and the intermediate transfer medium in which the notch processing is formed is referred to as an intermediate transfer medium 100. Further, the intermediate transfer medium 100 refers to both those in which the thermal transfer image 400 is not formed in the transfer layer 40 and those in which the thermal transfer image 400 is formed. Hereinafter, each component of the intermediate transfer medium 100 will be described.

(A) Release member The release member 110 has a function as a support member for supporting the transfer layer 40 on which the thermal transfer image 400 of the intermediate transfer medium 100 is formed, and the release member 110 of the transfer layer 40 to the transferred body. Recovered after transfer. In the release member 110, the back surface layer 90, the support 80, and the adhesive layer are laminated in this order.

(I) Support The support 80 is not particularly limited as a material, and for example, polyester having high heat resistance such as polyethylene terephthalate and polyethylene naphthalate, polypropylene, polycarbonate, cellulose acetate, polyethylene derivative, polyamide, and polymethylpentene. Such as stretched or unstretched film of plastic can be used. Further, among these, alloys of two or more kinds of materials or laminated ones may be used. The thickness of the support 80 can be appropriately selected depending on the required rigidity, heat resistance, etc., but is preferably in the range of 3 μm or more and 30 μm or less, and preferably in the range of 4 μm or more and 15 μm or less. It is more preferable to have.

(Ii) Adhesive layer The adhesive layer 70 holds the transfer sheet 120 composed of the transfer layer 40 and the protective sheet 50 so as not to separate from the release member 110 until the transfer sheet 120 is transferred to the transfer target. It is provided for this purpose. Therefore, after the transfer of the transfer sheet 120, the adhesive layer may or may not have adhesiveness, but from the viewpoint of the rewindability of the release member described later, it has adhesiveness. It is preferable that there is no such thing.
The adhesive layer 70 is not particularly limited as a material, and for example, polyethylene, polypropylene, polybutene, polyhexene, ethylene-propylene copolymer, ethylene-butene copolymer, ethylene-hexene copolymer, ethylene-octene copolymer weight. Polyolefins such as coalescing, propylene-butadiene copolymers, α-olefin-unsaturated carboxylic acid copolymers and modified products thereof, acrylic resins, vinyl resins, polyesters, urethane resins, polyamides, epoxy resins and rubbers. A known material containing a resin, an ionomer, a silicone resin or the like as a main component can be used. Moreover, you may use 2 or more kinds of materials among these. Among these, acrylic resin, silicone resin, polyethylene, polypropylene and α-olefin-unsaturated carboxylic acid copolymer are preferable from the viewpoint of mold releasability. The thickness of the adhesive layer 70 is not particularly limited, but is preferably in the range of 0.1 μm or more and 50 μm or less, and more preferably in the range of 1 μm or more and 20 μm or less.

The method for forming the adhesive layer 70 is also not particularly limited, and a coating liquid for an adhesive layer in which the above materials and the like are dispersed or dissolved in an appropriate solvent is prepared, and this coating liquid is applied to the support 80 and dried. Can be formed. The method for applying the coating liquid for the adhesive layer is also not particularly limited, and a known coating method can be appropriately selected and used. Examples of the coating method include a gravure printing method, a screen printing method, and a reverse coating method using a gravure plate. Further, other coating methods can also be used.

(Iii) Back surface layer When the adhesive layer 70 has adhesiveness after transfer of the transfer sheet 120, releasability is provided on the surface of the support 80 opposite to the surface on which the adhesive layer 70 is provided. The back surface layer 90 may be provided. The release member 110 collected after the transfer layer 40 of the intermediate transfer medium 100 is transferred to the transfer material is wound in a reel shape, and at this time, the inner and outer release members 110 that overlap each other by being wound are wound. The adhesive layer 70 of the inner mold release member 110 and the back surface of the support 80 of the outer mold release member 110 (the surface opposite to the adhesive layer 70) come into contact with each other. Therefore, if the two are adhered to each other, the position cannot be corrected even if the release member 110 meanders, and a problem occurs in the recovery process of the release member 110. On the other hand, when the back surface layer 90 having releasability is formed on the back surface of the support 80, when the releasing member 110 is wound, the adhesive layer 70 of the inner releasing member 110 and the outer releasing member 110 are formed. Since it does not adhere to the back surface layer 90 of the 110, the release member 110 can be satisfactorily wound while correcting the meandering of the release member 110 as appropriate. That is, the rewindability of the release member is good.

When the back surface layer 90 is provided by a method of adding a layer different from the support 80, the material is not particularly limited, and for example, waxes, silicone wax, silicone resin, silicone modified resin, fluororesin, etc. Fluoromodified resin, polyvinyl alcohol resin, acrylic resin, polyester, heat-crosslinkable epoxy-amino resin, heat-crosslinkable alkyd-amino resin and the like can be used. Moreover, you may use 2 or more kinds of materials among these. Further, the back surface layer 90 is not only a method of adding a new layer to the support 80 in this way, but also a known water repellent processing technique such as fine unevenness processing on the surface of the support 80 or plasma treatment. It can also be provided by a method of imparting releasability to the support 80 itself. The surface tension of the back surface layer 90 is preferably 5 mN / m or more and 35 mN / m or less, and more preferably the surface tension of the back surface layer 90 is 10 mN / m or more and 28 mN / m or less. When the surface tension of the back surface layer 90 is 5 mN / m or more and 35 mN / m or less, the material selection range of the support member to be subjected to the surface treatment or the back surface layer when the back surface layer is added can be expanded and compared. Releasability can be ensured at a low cost. Further, since the surface tension of the back surface layer 90 is 10 mN / m or more and 28 mN / m or less, the mold release is recovered after the transfer layer 40 is transferred to the transfer material regardless of the surrounding temperature and humidity environment. The member 110 can be smoothly wound into a reel shape. The surface tension was measured by using a wet tension test mixture (manufactured by Kanto Chemical Co., Ltd.) in accordance with JIS K6768 (1999) "Plastic film and sheet wet tension test method".

(B) Transfer Sheet The transfer sheet 120 is a layer in which a release layer 60, a protective sheet 50, and a transfer layer 40 are laminated in this order, and the transfer layer 40 is exposed on one outermost surface of the intermediate transfer medium 100. Is.

(I) Release layer The release layer 60 covers the transfer layer 40 and the protective sheet 50 on which the thermal transfer image 400 of the intermediate transfer medium 100 is formed when the adhesive layer 70 has adhesiveness after the transfer of the transfer sheet 120. It is provided to improve the separation suitability of the protective sheet 50 to be transferred from the release member 110 when transferring to the transfer body. Since the material and thickness of the release layer 60 are the same as those of the back surface layer 90, detailed description thereof will be omitted. If the adhesive layer 70 is made of a material that does not have adhesiveness after the transfer sheet 120 is transferred, the release layer 60 may not be provided.

(Ii) Protective sheet The protective sheet 50 has a function of a protective film that covers the thermal transfer image 400 when the transfer layer 40 on which the thermal transfer image 400 of the intermediate transfer medium 100 is formed is transferred to the transferred body. .. The material is not particularly limited as long as it has transparency that allows the thermal transfer image to be clearly seen, and has abrasion resistance, chemical resistance, and weather resistance that can withstand long-term use. For example, polyethylene terephthalate film, 1,4-polycyclohexylene methylene terephthalate film, polyethylene naphthalate film, polyphenylene sulfide film, polystyrene film, polypropylene film, polysulfone film, aramid film, polycarbonate film, polyvinyl alcohol film, cellophane, acetic acid. Cellulous derivatives such as cellulose, polyethylene film, polyvinyl chloride film, nylon film, polyimide film, ionomer film and the like can be used. The thickness of the protective sheet 50 is not particularly limited, but is preferably in the range of 0.5 μm or more and 100 μm or less, and more preferably in the range of 10 μm or more and 40 μm or less.

Further, the protective sheet 50 is laminated on the support 80 of the release member 110 with the release layer 60 and the adhesive layer 70 interposed therebetween. That is, the protective sheet 50, the release layer 60, the adhesive layer 70, and the support 80 are laminated in this order. As described above, the support 80 is arranged so as to face the adhesive layer 70 directly, but the release layer 60 is arranged between the protective sheet 50 and the adhesive layer 70. From this, when the release member 110 is to be peeled off from the intermediate transfer medium 100, the release member 110 and the transfer sheet 120 can be easily peeled off from the interface between the support 80 and the adhesive layer 70 of the release member 110. Can be separated. However, as described above, when the adhesive layer 70 is made of a material that does not have adhesiveness after transfer of the transfer sheet 120, a release layer for the purpose of ensuring peelability to a material having strong adhesiveness. 60 may not be provided.

(Iii) Transfer layer The transfer layer 40 is a layer in which a release layer 30, a protective layer 20, and a receiving layer 10 are laminated in this order, and the receiving layer 10 is a layer exposed on one outermost surface of the intermediate transfer medium 100. .. The transfer layer 40 is a layer that can be peeled off from the protective sheet 50 by applying various transfer means, for example, energy. In order to improve the peelability, the peeling layer 30 described later may be provided at the position closest to the protective sheet 50 of the transfer layer 40.

(Iv) Receptive layer A thermal transfer image 400 is formed on the receptive layer 10, and a transfer layer 40 including the receptive layer 10 is transferred to a transfer target to form a print. The receiving layer 10 is generally composed mainly of a thermoplastic resin. The material for forming the receiving layer 10 is not particularly limited, and a known receiving layer to be used as an intermediate transfer medium can be appropriately selected and used.

For example, polyolefins such as polypropylene, halogenated resins such as polyvinyl chloride or polyvinylidene chloride, polyvinyl acetates, vinyl chloride-vinyl acetate copolymers, ethylene-vinyl acetate copolymers or vinyl resins such as polyacrylic acid esters, Polyesters such as polyethylene terephthalate or polybutylene terephthalate, copolymers of olefins such as polystyrene, polyamide, ethylene or propylene and other vinyl polymers, cellulose resins such as ionomer or cellulose diastase, solvent-based resins such as polycarbonate and acrylic resins Can be used. Among these, polyester and vinyl chloride-vinyl acetate copolymer are preferably used, and vinyl chloride-vinyl acetate copolymer is more preferable. Further, among these, two or more kinds may be contained.

The receiving layer 10 may contain a mold release agent together with the above resin component. Examples of the release agent include solid waxes such as polyethylene wax, amide wax, and Teflon (registered trademark) powder, fluorine-based or phosphate ester-based surfactants, silicone oil, reactive silicone oil, and curable silicone oil. Various modified silicone oils and various silicone resins can be used. Further, the thickness of the receiving layer 10 may be, for example, in the range of 1 μm or more and 10 μm or less.

(V) Protective layer The protective layer 20 may be provided to impart plasticizer resistance, and is not particularly limited as a material. For example, polyester, polycarbonate, acrylic resin, vinyl chloride, ultraviolet absorbing resin, epoxy resin, polystyrene, polyurethane, acrylic urethane resin, resins obtained by modifying each of these resins with silicone, mixtures of these resins, ionizing radiation curable. Resin, ultraviolet absorbing resin, etc. can be used. Of these, acrylic resin, polyester, and vinyl chloride are preferably used, and acrylic resin and polyester are even more preferable. Further, the thickness of the protective layer 20 may be, for example, in the range of 1 μm or more and 10 μm or less.

The protective layer 20 containing an ionizing radiation curable resin is particularly excellent in plasticizer resistance. A known ionizing radiation curable resin can be used. For example, a radically polymerizable polymer or oligomer is crosslinked and cured by ionizing radiation irradiation, a photopolymerization initiator is added as necessary, and an electron beam is used. It can be polymerized and crosslinked by ultraviolet rays. The protective layer 20 containing the ultraviolet absorbing resin is excellent in imparting light resistance to the printed matter.

As the ultraviolet absorbing resin, for example, a resin obtained by reacting and binding a reactive ultraviolet absorber to a thermoplastic resin or the above-mentioned ionizing radiation curable resin can be used. More specifically, an addition polymerizable double bond to a known non-reactive organic ultraviolet absorber such as salicylate type, benzophenone type, benzotriazole type, substituted acrylonitrile type, nickel chelate type and hindered amine type. (For example, vinyl group, acryloyl group, metaacryloyl group, etc.), alcoholic hydroxyl group, amino group, carboxyl group, epoxy group, isocyanate group and other reactive groups are introduced.

Examples of the material of the release layer 30 include waxes, silicone wax, silicone resin, silicone-modified resin, fluororesin, fluorine-modified resin, polyvinyl alcohol resin, acrylic resin, polyester resin, heat-crosslinkable epoxy-amino resin, and heat. Crosslinkable alkyd-amino resin or the like can be used. Further, among these, two or more kinds may be contained. The thickness of the release layer 30 may be, for example, in the range of 0.5 μm or more and 5 μm or less.

When an image is formed on the receiving layer 10 of the transfer layer 40 by a thermal transfer method, the energy applied to the transfer sheet 120 at the time of image formation is higher than that of other image forming methods, and this high energy causes photographic wrinkles at the time of forming an image. And uneven printing are likely to occur. Therefore, the print suitability when forming an image on the transfer layer 40 tends to decrease. However, in the intermediate transfer medium 100 of the present embodiment, the transportability of the printer can be improved by the presence of the release member 110, so that it is possible to suppress printing wrinkles and printing unevenness due to the low transportability of the printer, and transfer. The printability when forming an image on the layer 40 can be improved.

(B) Thermal Transfer Sheet Next, the thermal transfer sheet 200 will be briefly described. As shown in FIG. 2A, the thermal transfer sheet 200 has a three-layer structure in which the coloring material layer 230 is provided on one surface of the base material 210 and the back surface layer 220 is provided on the other surface. The thermal transfer sheet 200 and the intermediate transfer medium 100 are stacked so that the color material layer 230 of the thermal transfer sheet 200 and the receiving layer 10 of the intermediate transfer medium 100 face each other, and a predetermined value is provided from the back layer 220 of the thermal transfer sheet 200 by a thermal head or the like. By applying heat, the heat transfer image 400 can be formed on the receiving layer 10. However, although the present disclosure shows an example of the case where the image formation is performed by the thermal transfer method, the image forming method is not limited to this, and other methods such as an inkjet method may be used.

(C) Description of Manufacturing Method of Photographic Paper Next, the manufacturing method of the photographic paper of the embodiment will be described with reference to the drawings.

(A) Preparation of Intermediate Transfer Medium As shown in FIG. 1A, the intermediate transfer medium 100 of the present embodiment manufactures the intermediate transfer medium 100a in which the release member 110 and the transfer sheet 120 are laminated, and the intermediate transfer medium 100a is manufactured. A notch 310 is formed in the transfer sheet 120 of the intermediate transfer medium 100a. In FIG. 1A, the heat transfer image 400 is formed on the receiving layer 10 of the transfer layer 40, but this step prepares the intermediate transfer medium 100 in the stage before the heat transfer image 400 is formed. is there.

As an example of the method for producing the intermediate transfer medium 100a, a method for forming the adhesive layer 70 by a dry laminating method will be described. First, the transfer sheet 120 provided with the transfer layer 40 on one surface of the protective sheet 50 is formed. Next, the release layer 60 is formed on the other surface of the protective sheet 50, and then the coating liquid is applied and dried to form the adhesive layer 70, and then the adhesive layer 70 and the release member 110 are formed. The support 80 is crimped and bonded. Further, a coating liquid for an adhesive layer is applied to the support 80 and dried to form an adhesive layer 70, on which a transfer layer 40 is provided on one surface of the protective sheet 50 and a mold release layer is provided on the other surface. The transfer sheet 120 on which the layer 60 is formed may be laminated. Further, a back surface layer 90 may be appropriately formed on the surface of the support 80 opposite to the adhesive layer 70.

On the other hand, as another example in which the adhesive layer 70 is performed by a wet laminating method, first, a transfer sheet 120 having a transfer layer 40 provided on one surface of the protective sheet 50 is formed. Next, after forming the release layer 60 on the other surface of the protective sheet 50, the coating liquid for the adhesive layer is applied. After that, in a wet state of the adhesive layer coating liquid, the adhesive layer coating liquid applied to the other surface side of the protective sheet 50 and the support 80 constituting the release member 110 are crimped. It can also be pasted together.

Further, as an example of a method for producing the intermediate transfer medium 100a different from the above, for example, a production method using a melt-extruded resin layer can be mentioned. In the sand laminating method using the melt-extruded resin layer, first, the transfer sheet 120 in which the transfer layer 40 is provided on one surface of the protective sheet 50 is formed. Next, the molten resin is extruded and poured between the protective sheet 50 constituting the transfer sheet 120 and the support 80 constituting the release member 110. After that, it is a manufacturing method in which the support 80 of the release member 110 and the protective sheet 5 of the transfer sheet 120 are bonded to each other by the melt-extruded resin layer formed thereby.

Alternatively, in the tandem laminating method as another example using the melt-extruded resin layer, first, the molten resin is extruded on the support 80 of the release member 110 to form the melt-extruded resin layer. Next, the transfer sheet 120 having the transfer layer 40 provided on one surface of the protective sheet 50 is supplied onto the melt-extruded resin layer formed on the support 80, and is protected from the support 80 by the melt-extruded resin layer. This is a manufacturing method in which the sheet 50 is bonded together. In this manufacturing method, instead of forming the melt-extruded resin layer on the support 80, a melt-extruded resin layer is formed on the protective sheet 50, and the release member 110 is supplied on the melt-extruded resin layer. You may. Further, in the manufacturing method exemplified above, the protective sheet 50 before the transfer layer 40 is provided and the support 80 may be bonded to each other with a melt-extruded resin layer, and then the transfer layer 40 may be provided on the protective sheet 50. Good.

In any case, in the manufacturing method using the melt-extruded resin layer as described above, the melt-extruded resin is formed in place of the release layer 60 and the adhesive layer 70 as shown in FIG. It is included in the configuration of the intermediate transfer medium 100a before the notch formation and the intermediate transfer medium 100 after the notch formation of the present disclosure.

The intermediate transfer medium 100 of the present embodiment is cut into the same pattern at predetermined intervals with respect to the intermediate transfer medium 100a. The notch processing reaches, for example, from the surface of the transfer sheet 120 opposite to the release member 110, that is, the exposed surface of the receiving layer 10, to the surface of the transfer sheet 120 on the release member 110 side, that is, the release layer 60. It may be a half cut which is a continuous notch. In this case, the release member 110 may not be half-cut at all, or may be half-cut to the middle of the layer of the release member 110.

Further, the notch may be a perforation which is an intermittent notch when the transfer sheet 120 is viewed from the transfer layer 40 side toward the release member 110 side. In addition, the depth of cut may change intermittently or continuously depending on the location. When the transfer sheet 120 is viewed from the transfer layer 40 side toward the release member 110 side, the contour line of the notch (in the case of a perforation, the contour line formed by the broken line) is a fixed region of the transfer layer 40. Is formed so as to surround the. For example, as shown in FIG. 1B, it may be a substantially quadrangle with rounded corners. The shape can be arbitrarily determined such as an ellipse, an oval, a triangle, a trapezoid, a parallelogram, and a polygon.

Further, the region to be half-cut can be limited so that only the portion of the image formed on the transferred body that requires higher durability is covered with the protective sheet. For example, as shown in FIG. 8, a plurality of half-cut portions may be provided on a part of the card. FIG. 8A is a plan view of the intermediate transfer medium 102 viewed from a direction perpendicular to the main surface, and FIG. 8B is a plan view of the printed matter 602 viewed from the same direction as described above. is there. The notches in this case are provided as notches 312 and 313 separated into two places for one printed matter.

Even in this case, the heat transfer image 400a can be formed by reducing the margins at the outer edge of the transferred body as much as possible, and the protective sheet 50a having a role of protecting the heat transfer image 402a dispersedly formed in a plurality of places of the transferred body is provided. , Corresponding to the position of each thermal transfer image 402a, each can be divided and arranged in a region one size smaller than the thermal transfer image 402a.

In the notch processing, for example, the intermediate transfer medium 100a is supplied between the upper mold to which the cutter blade is attached and the pedestal while the transfer layer 40 is arranged so as to face upward, and the upper mold is moved downward. , A cutter blade can be inserted from the transfer layer 40 side of the intermediate transfer medium 100a to perform cutting halfway in the thickness direction. The cutting process corresponding to the transfer to one unit of the transferred body is performed, and then the cutting process corresponding to the transfer to another adjacent unit to be transferred is performed. By repeating this, continuous cutting can be performed. It is also possible to cut a plurality of sections at once. In this way, for example, as shown in FIG. 3, notches 310 can be formed at substantially equal intervals along the longitudinal direction of the intermediate transfer medium 100.

In addition to the method of inserting the intermediate transfer medium 100a between the upper mold to which the cutter blade is attached and the pedestal to move the upper mold up and down, the notch processing method includes a cylinder type rotary cutter method and a laser processing means. There is no particular limitation as long as it is a method capable of forming a notch as a result, such as a heat treatment processing method according to.

As described above, the depth for performing the notch processing may be set as long as a notch is formed from the surface of the transfer sheet 120 opposite to the release member 110 to the surface of the release member 110. Even if the depth reaches more than that, for example, about half the depth of the support 80 of the release member 110, there is no problem. However, if it is too deep, there may be a problem that the release member 110 is cut when the transfer sheet 120 is transferred to the transfer target, so that the allowable depth is increased in consideration of the strength of the support 80. It is preferable to set a limit value.

Further, prior to the formation of the notch 310, as shown in FIG. 3, detection marks 710 may be provided at predetermined positions at intervals corresponding to one unit of the transfer region to the transferred body. With such a detection mark 710, when the intermediate transfer medium 100a is mechanically continuously cut, the cut 310 can be formed at an accurate position after the detection mark 710 is detected by the sensor. Further, as will be described later, a thermal transfer image can be formed on the intermediate transfer medium 100 which has been cut and formed in another step, and the detection mark 710 is also referred to when the transfer layer 40 is transferred to the transferred body. Then, the thermal transfer image can be formed and the transfer layer 40 can be transferred to the transferred body at an accurate position.

Further, the detection mark 710 may be formed as a notch at the same time as the notch 310 is formed, instead of being formed by a thermal transfer image or the like. In that case, the detection mark 710 may be a half-cut similar to the notch 310, the intermediate transfer medium 100 may be penetrated in the thickness direction, or a perforation may be used.

However, the formation of the detection mark 710 is not essential, and even without the detection mark 710, the same alignment can be achieved by directly detecting the shape of the notch 310 with a camera or a sensor in a machine in a subsequent process.

As described above, the preparation step of the intermediate transfer medium is completed by preparing the intermediate transfer medium 100 that has undergone the process of manufacturing the intermediate transfer medium before forming the notch and the step of forming the notch.

(B) Thermal Transfer Image Forming Step The thermal transfer image forming step is a step of forming a thermal transfer image on the transfer layer 40 of the transfer sheet 120 of the intermediate transfer medium 100 by using the thermal transfer sheet 200 described above. This process will be described with reference to FIG. FIG. 4 shows a step of forming a thermal transfer image by a thermal transfer sheet 200 on an intermediate transfer medium 100 using a thermal transfer printer 501, and a step of obtaining a print 600 by transferring a transfer sheet 120 including a thermal transfer image to a transfer body 420. It is a schematic schematic diagram explaining.

The first supply unit 517 of the thermal transfer printer 501 is loaded with a take-up in which the intermediate transfer medium 100 is wound in a ribbon shape. The first supply unit 517 rotates the winding of the intermediate transfer medium 100 and conveys it in a long strip shape to the printing unit 505 and the transfer unit 506.

The printing unit 505 of the thermal transfer printer 501 is illustrated so that the thermal head 513, the platen roll 514 that can be driven to rotate provided below the thermal head 513, and the thermal head 513 can be moved up and down with respect to the platen roll 514. It is equipped with a means of raising and lowering. In the thermal transfer printer 501, the intermediate transfer medium 100 supplied from the first supply unit 517 passes between the thermal head 513 and the platen roll 514.

Further, in the thermal transfer printer 501, the thermal transfer sheet 200 passes between the thermal head 513 and the platen roll 514 from the supply roll side as the second supply unit 511 via the guide roll 512, and passes through the guide roll 515. It is wound on the take-up roll 516 via. Between the thermal head 513 and the platen roll 514, the color material layer 230 of the thermal transfer sheet 200 and the transfer layer 40 of the intermediate transfer medium 100 face each other (not shown).

In the thermal transfer printer 501, the thermal head 513 heats the color material layer 230 of the thermal transfer sheet 200, and transfers a part of the heated color material layer 230 onto the transfer layer 40. Here, the thermal transfer printer 501 is provided with a mark detection unit 560 on the upstream side of the thermal head 513, and can detect the presence / absence and the position of the detection mark 710 as shown in FIG. 3 in advance. The detection mark 710 may be formed in advance by coloring such as black using a thermal transfer sheet similar to the thermal transfer sheet 200.

Further, the mark detection unit 560 may be a sensor that irradiates, for example, visible light or infrared light and measures the reflectance thereof. Further, such a detection mark 710 does not exist, and the mark detection unit 560 may directly photograph the outline of the notch 310 with a camera or the like as shown in FIG. 3 to detect the notch position.

As described above, after aligning the position where the notch 310 of the intermediate transfer medium 100 is formed with the color material layer 230 of the thermal transfer sheet 200, the thermal head 513 is lowered toward the platen roll 514 to lower the thermal transfer sheet. The thermal head 513 is brought into contact with the platen roll 514 via the 200 and the intermediate transfer medium 100. Further, the platen roll 514 is rotationally driven to convey the thermal transfer sheet 200 and the intermediate transfer medium 100 to the downstream side. During this time, the thermal head 513 selectively heats the color material layer 230 of the thermal transfer sheet 200 based on the data transmitted to the thermal head 513. As a result, the predetermined thermal transfer image is transferred to the transfer layer 40 of the intermediate transfer medium 100.

(C) Transfer Step of Transfer Sheet Following the above, a transfer step of the transfer sheet for transferring a part of the transfer sheet 120 of the intermediate transfer medium 100 on which the thermal transfer image is formed to the transferee 420 will be described with reference to FIG. .. The thermal transfer printer 501 conveys the intermediate transfer medium 100 on which the thermal transfer image is transferred to the transfer unit 506 via the guide roll 518. In the thermal transfer printer 501, the transfer unit 506 includes a heat roller 520 and a pressure roll 521 provided below the heat roller 520. The transfer unit 506 transfers a part of the transfer sheet 120 to the transfer target 420 supplied from the third supply unit 507. However, the heat roller 520 is an example of the transfer structure of the intermediate transfer medium 100 in the transfer unit 506, and may be replaced with a thermal head other than the heat roller or a heating head such as a ceramic heater.

In the thermal transfer printer 501, the third supply unit 507 is a feeding device that feeds out one sheet at a time, for example, a card to be transferred 420, which is a card, in accordance with the transfer of the intermediate transfer medium 100, and the transferred body 420. It has a conveyor device and the like for transporting. The transferred body 420 may be a long roll-up shape.

The transfer unit 506 heats the surface of the transfer sheet 120 of the intermediate transfer medium 100 superposed on the transfer target 420 between the heat roller 520 and the pressure roll 521. As a result, a printed matter 600 in which a part of the transfer sheet 120 including a part of the transfer layer 40 and a part of the protective sheet 50 is transferred onto the transferred body 420 is obtained. In the thermal transfer printer 501, the printed matter 600 is conveyed to the discharge unit 508 and accumulated one by one. The release member 110 on which the transfer sheet 120 has been transferred is wound on the take-up roll 522.

Here, the transfer of the transfer sheet 120 from the intermediate transfer medium 100 to the transfer target 420 in the transfer unit 506 will be described in detail with reference to FIGS. 5, 6 and 7. FIG. 5 is a cross-sectional view showing a state in which the intermediate transfer medium 100 and the transferred body 420 are stacked and sandwiched between the heat roller 520 and the pressure roll 521 in the transfer unit 506. FIG. 6 is a cross-sectional view showing a part 110a of the release member 110 after the printed matter 600 and the part 120a of the transfer sheet 120 after applying heat pressure to the transfer unit 506 are transferred. a) shows the latter, and FIG. 6B shows the former. Further, FIG. 7 is a plan view of the printed matter 600 shown in FIG. 6B when viewed from the transfer sheet 120a side toward the transfer subject 420 side.

In FIG. 5, it is assumed that the transferred body 420 and the intermediate transfer medium 100 stacked on each other are conveyed from the right side to the left side of the paper surface as shown in the drawing. Predetermined heat is sequentially transferred from the heat roller 520 from the left side to the right side of the paper surface of the transfer sheet 120 through the mold release member 110, and the predetermined portion of the transfer sheet 120 is heated. At this time, the portion of the transfer layer 40 that is in contact with the transferred body 420 is sequentially transferred from the left end to the transferred body 420 side by the heat transferred from the heat roller 520. When the transfer layer 40 being transferred reaches the notch 310a on the left side of the paper surface, this portion naturally separates. Therefore, the transfer layer 40 on the right side of the notch 310a is the protective sheet 50 which is the upper end of the notch 310. Is sequentially transferred to the transfer target 420 side together with.

Further, when the transferred transfer layer 40 and the protective sheet 50 eventually reach the notch 310b on the right side of the paper surface, this portion naturally separates, so that the transfer layer 40 on the right side of the notch 310b is the protective sheet 50. It is separated from the above, and only the transfer layer 40 is sequentially transferred to the transfer target 420 side.

As a result of the above, as shown in FIG. 6B, a printed matter 600 to which the transfer layer 40 and the protective sheet 50 are transferred is obtained. Here, for convenience, the portion of the transfer sheet 120 transferred to the transfer body 420 as the printed matter 600 is referred to as the transfer sheet 120a, and the transfer layer 40, the protective sheet 50, and the release layer 60 constituting the transfer sheet 120a are used. , The transfer layer 40a, the protective sheet 50a, and the release layer 60a, respectively. Further, the receiving layer 10, the protective layer 20 and the peeling layer 30 constituting the transfer layer 40a are designated as the receiving layer 10a, the protective layer 20a and the peeling layer 30a, respectively. Further, as shown in FIG. 6A, the release member 110 which is the remaining transferred member 110 which does not constitute the printed matter 600 is used as the release member 110a, and the transfer sheet 120 remaining on the release member 110a side is the transfer sheet 120b. And. Further, the transfer layer 40, the protective sheet 50 and the release layer 60 constituting the transfer sheet 120b are designated as the transfer layer 40b, the protective sheet 50b and the release layer 60b, respectively. Further, the receiving layer 10, the protective layer 20 and the peeling layer 30 constituting the transfer layer 40b are designated as the receiving layer 10b, the protective layer 20b and the peeling layer 30b, respectively.

At this time, as shown in FIG. 6B, the width D1 of the protective sheet 50a and the release layer 60a on the cross section is substantially the same as the width of the notch 310 on the cross section, but is arranged in the lower layer thereof. The width D2 on the cross section of the transfer layer 40a can be made slightly larger than D1. That is, when the transfer sheet 120 is viewed from the transfer layer 40 side toward the release member 110 side, the region formed by the notch 310 surrounding the predetermined region of the transfer layer 40 and the region of the protective sheet 50a are substantially the same. Although it is D1, the region of the transfer layer 40a can be a region D2 that is one size larger than the region formed by the notch 310 by D3 on each side. This is because, as described above, the transfer layer 40 can be transferred to the transferee 420 in a region larger than this, regardless of the region of the protective sheet 50 surrounded by the notch 310.

As a result of the above, as shown in FIG. 6A, the release member 110a after the transfer sheet 120a is transferred to the transferred body 420 has a gap D4 which is substantially the same width D4 as the width of the notch 310 on the cross section. The protective sheet 50b and the release layer 60b that were not transferred remain, and a gap having a width D5 larger than this remains in the lower layer thereof, and the transfer layer 40b that was not transferred remains.

As described above, in the transfer step of the transfer sheet of the present embodiment, as shown in the plan view of the printed matter of FIG. 7, the thermal transfer image 400a can be formed with the margin of the outer edge portion as small as possible with respect to the transferred object. .. Further, the protective sheet 50a having a role of protecting the heat transfer image 400a can be arranged in a region one size smaller than the heat transfer image 400a. Further, since the protective sheet 50a is transferred as a transfer sheet 120a integrated with the transfer layer 40a on which the thermal transfer image 400a is formed, no special alignment or other control is required. Further, even if the transfer position of the protective sheet 50a to the transfer target is displaced, the protective sheet 50a can be formed to be one size smaller in consideration of the displacement of the transfer target. , It is possible to suppress a decrease in the production yield of printed matter.

In the present embodiment, the transfer layer 40 is exemplified as a laminated layer of the receiving layer 10, the protective layer 20, and the peeling layer 30, but layers other than the receiving layer 10 are optional or layers other than those exemplified. May be laminated. Further, the transfer sheet 120 is illustrated as a laminate of the transfer layer 40, the protective sheet 50, and the release layer 60, but other than the protective sheet 50 is optional, or a layer other than the example is used. It may be laminated. Similarly, the release member 110 is illustrated as having the adhesive layer 70, the support 80, and the back surface layer 90 laminated, but other than the support 80 is optional, or layers other than those exemplified are laminated. May be. The portion having the function of the adhesive layer 70 needs to be formed on either the transfer sheet 120 side or the release member 110. However, as described above, when the melt extruded resin layer is used, the melt extruded resin layer is formed on the support 80 or the melt extruded resin layer is formed on the protective sheet 50. The extruded resin layer can be substituted for the adhesive layer 70. This is because the support 80 and the protective sheet 50 are bonded to each other by the melt-extruded resin layer to obtain an adhesive force. Further, as described above, it is also optional to provide the back surface layer 90 on the surface of the support 80 opposite to the adhesive layer 70.

Next, the present invention will be described in more detail with reference to examples.
