藉由一實施形態之熱轉印薄片10，則組合一實施形態之熱轉印薄片10與被轉印體100，於被轉印體100之一面上，進行使用了含紅外線吸收材料層2的特別圖像50A之形成、及使用了色材層3的熱轉印圖像50B之形成，可得到於被轉印體100之一面上，設置含有紅外線吸收材料的特別圖像50A、和含有色材的熱轉印圖像50B的印刷物200。　　[0047] 在使用一實施形態之熱轉印薄片10而形成的印刷物200的特別圖像50A之偵測係例如可使用對印刷物200照射紅外線，利用特別圖像50A所含有的紅外線吸收材料會吸收紅外線的特性，利用依紅外線之吸收幅度所致的光學特性的方法等。作為特別圖像50A之偵測器係例如可舉出紅外線掃描器等。　　[0048] 然而，在使用熱轉印薄片之色材層而形成的熱轉印圖像50B為對於近紅外光區域、及紅外光區域之波長的吸收性高的圖像的情況，換言之，用以形成熱轉印圖像50B之色材層為對於近紅外光區域、及紅外光區域之波長的吸收性高的色材層的情況係在使用了上述紅外線掃描器等的特別圖像50A之偵測時，會產生與特別圖像50A一起偵測到熱轉印圖像50B的問題、或是使用對於近紅外光區域、及紅外光區域之波長的吸收性高的色材層而形成的熱轉印圖像50B，對特別圖像50A之偵測帶來影響，無法正確地偵測特別圖像50A的問題。　　[0049]

具體而言，在色材層之在波長750nm以上、1400nm以下之範圍的最大反射率為未達50%的情況係在將包含紅外線吸收材料的特別圖像50A，使用紅外線掃描器等而偵測時，變得容易產生與特別圖像50A一起偵測到熱轉印圖像50B的問題、或熱轉印圖像50B對特別圖像50A之偵測性帶來影響，無法正確地偵測特別圖像50A的問題。　　[0053] 理想的第1實施形態之色材層3係該色材層之在波長750nm以上、1400nm以下之範圍的最大反射率為80%以上。藉由理想的第1實施形態之色材層3，則使用紅外線掃描器等，可謀求偵測包含紅外線吸收材料的特別圖像50A時之偵測性之更提昇。　　[0054] 又，於包含紅外線吸收材料的特別圖像50A上，形成熱轉印圖像50B，將該特別圖像50A之偵測，使用偵測830nm之波長的感測器而進行的情況之理想的第1實施形態之色材層3係色材層之在波長750nm以上、950nm以下之範圍內之任一之波長的反射率成為50%以上，特別是80%以上，較理想為在750nm以上、950nm以下之全範圍，反射率成為50%以上，特別是80%以上。　　[0055]

在被轉印體100由塑膠薄膜所構成的情況，作為塑膠薄膜係例如可舉出聚對苯二甲酸乙二酯(PET)、聚對苯二甲酸丁二酯(PBT)、聚萘二甲酸乙二酯(PEN)、尼龍6、尼龍6,6等之聚醯胺系樹脂、聚乙烯、聚丙烯等之聚烯烴系樹脂、聚氯乙烯等之乙烯基系樹脂、聚丙烯酸酯、聚甲基丙烯酸酯、聚甲基甲基丙烯酸酯等之丙烯酸系樹脂、聚醯亞胺、聚苯硫醚(PPS)、聚苯乙烯、丙烯腈-苯乙烯共聚物(AS樹脂)、丙烯腈-丁二烯-苯乙烯共聚物(ABS樹脂)等之苯乙烯系樹脂、玻璃紙、乙酸纖維素、硝基纖維素等之纖維素系薄膜等。塑膠薄膜亦可為將上述的樹脂設為主成分的共聚樹脂或混合體(含合金)。　　[0106] 被轉印體100本身亦可未具備接受層，但在藉由昇華型熱轉印方式而形成熱轉印圖像50B的情況，一實施形態之熱轉印薄片10為於未具備包含接受層5A的第1轉印層(5)的情況(參照第1(a)、(b)圖)，被轉印體100係於一面具備接受層為理想。又，被轉印體100之兩面亦可具備接受層。尚，一實施形態之熱轉印薄片10為於具備包含接受層5A的第1轉印層(5)的情況(參照第2(a)、(b)圖)，被轉印體100係不需要於熱轉印圖像50B之形成面具備接受層。　　[0107] 關於被轉印體100之厚度係無特別限定，但3μm以上、800μm以下之範圍為理想，100μm以上、600μm以下之範圍內為較理想。　　[0108] (其他實施形態之熱轉印薄片) 　　以上，關於一實施形態之熱轉印薄片舉出具體的例子而說明，但其他實施形態之熱轉印薄片10係呈現於基材之一面上，未設置含紅外線吸收材料層2，已設置上述第1實施形態之色材層3、或第2實施形態之色材層的構成。其他實施形態之熱轉印薄片10係事先，為了於已形成特別圖像50A的被轉印體上形成熱轉印圖像50B而使用的熱轉印薄片。藉由其他之實施形態之熱轉印薄片10，事先，於已形成特別圖像50A的被轉印體上，使用上述第1實施形態之色材層3、或第2實施形態之色材層3而形成熱轉印圖像50B，則可得到具有特別圖像50A及熱轉印圖像50B，且可使用紅外線掃描器等而正確地偵測特別圖像50A的印刷物200。　　[0109] 其他實施形態之熱轉印薄片10係可設為於基材1之一面上，與上述第1實施形態之色材層3、或第2實施形態之色材層一起，依幀順序設置與含紅外線吸收材料層2相異的層的構成。作為與含紅外線吸收材料層2相異的層係可舉出上述第1轉印層(5)或第2轉印層(7)等。　　[0110] ＜熱轉印薄片之構成例＞　　第3圖~第5圖係表示在一實施形態之組合所使用的熱轉印薄片之構成之一例的概略剖面圖。　　[0111] 第3(a)圖所示的形態之熱轉印薄片10係於基材1之一面上，依幀順序設置含紅外線吸收材料層2、第1轉印層(5)、黃色色材層3Y、洋紅色色材層3M、青色色材層3C、第2轉印層(7)、黃色色材層3Y、洋紅色色材層3M、青色色材層3C、第2轉印層(7)。第3圖所示的形態之熱轉印薄片10係將各層設為「1面板」時，由印刷上流側(在圖示的形態係圖面之左側)，「6面板」係成為為了於被轉印體100之一面側形成圖像(形成第1畫面之圖像)而使用的面板，剩下之「4面板」係成為為了於被轉印體100之另一面側形成圖像(形成第2畫面之圖像)而使用的面板。尚，在被轉印體100不具有接受層的情況係可於第2轉印層(7)與黃色色材層3Y之間，設置第1轉印層(5)，藉由以第1轉印層(5)、黃色色材層3Y、洋紅色色材層3M、青色色材層3C、第2轉印層(7)所構成的「5面板」，於被轉印體100之另一面側形成圖像。又，如第3(b)圖所示，亦可調換第3(a)圖之「6面板」和「4面板」。又，亦可設為除去第2轉印層(7)的構成(無圖示)。又，在第3(c)圖所示的形態係將含紅外線吸收材料層2、第1轉印層(5)、黃色色材層3Y、洋紅色色材層3M、青色色材層3C、第2轉印層(7)、黃色色材層3Y、洋紅色色材層3M、青色色材層3C、第2轉印層(7)之「10面板」設為「1單元」時，該「1單元」被重覆設置。以下，有將形成於被轉印體100之一面側的圖像之情事稱為「第1畫面之圖像」、將形成於被轉印體之另一面側的圖像之情事稱為「第2畫面之圖像」的情況。　　[0112] 然而，在印刷的對位或出頭係在將各「面板」之集合體設為「1單元」時，以「1單元」單位進行，「1單元」係成為必需構成其他「1單元」與「1單元」的「面板」之配列成為同一。亦即，在第3圖所示的形態係無法將個別於被轉印體100之一面側形成「第1畫面之圖像」時所使用的「6面板」、和為了於被轉印體之另一面上形成「第2畫面之圖像」而使用的「4面板」設為「1單元」，有必要將匯集「6面板」和「4面板」的「10面板」設為「1單元」。然而，隨著構成「1單元」的「面板」數變多，內部存在用以檢測各層的熱轉印列印機之設計負荷變大的問題，構成「1單元」的「面板數」少為最佳。　　[0113] 於是，第4圖所示的形態之熱轉印薄片10係於基材1之一面上，將由含紅外線吸收材料層2、第1轉印層(5)、黃色色材層3Y、洋紅色色材層3M、青色色材層3C、第2轉印層(7)之「6面板」所構成的集合體設為「1單元」時，該「1單元」被重複設置。亦即，相對於在第3圖所示的形態係將為了於被轉印體之一面側形成「第1畫面之圖像」所使用的面板由「6面板」構成，和為了於被轉印體之另一面側形成「第2畫面之圖像」所使用的面板由「4面板」構成之情事而言，在第4圖所示的形態係將用以形成「第1畫面之圖像」及「第2畫面之圖像」之面板，共同由「6面板」構成，以將此「6面板」設為「1單元」而將構成「1單元」的面板數變少。　　[0114] 另一方面，在第4圖所示的形態係在將「第1畫面之圖像」設為包含特別圖像50A的圖像，將「第2畫面之圖像」設為不包含特別圖像50A的圖像的情況，亦因為將構成「1單元」的面板數變少，有使全部「1單元」包含含紅外線吸收材料層2的必要，會產生浪費變多的問題。　　[0115] 於是，第5圖所示的形態之熱轉印薄片10係於基材1之一面上，將由含紅外線吸收材料層2、第1轉印層(5)、黃色色材層3Y、洋紅色色材層3M、青色色材層3C、第2轉印層(7)之「6面板」所構成的集合體設為「1單元」時，使供於第1畫面之圖像及第2畫面之圖像之形成的面板一體化，作為2畫面之長度之「面板」。在圖示的形態係個別黃色色材層3Y、洋紅色色材層3M、青色色材層3C，成為2畫面之長度之「面板」。亦即，將1個之色材層，設為使用於第1畫面之圖像及第2畫面之圖像之形成的構成。藉由此形態之熱轉印薄片10，則以將使用在被形成於被轉印體之一面側及另一面側的圖像的層之「面板」長設為2畫面份之長度，將使用在被形成於任一面側的圖像的層之「面板」長設為1畫面份之長度之情事，可抑制因不被使用的「面板」所致的浪費。例如，藉由第5圖所示的形態之熱轉印薄片10，則使用「1單元」，於被轉印體100之一面上形成第1畫面之圖像，接著，使被轉印體100上下顛倒，同時退捲熱轉印薄片10，再次使用先前已使用的「1單元」，可於被轉印體100之另一面上形成第2畫面之圖像。尚，在第5圖所示的形態係為了將黃色色材層3Y、洋紅色色材層3M、青色色材層3C，使用於第1畫面之圖像及第2畫面之圖像之形成，所以將該「面板」長設為2畫面份之長度，但亦可將此以外之層，例如，將第1轉印層(5)或第2轉印層(7)之「面板」長設為2畫面份之長度。又，亦可重複設置「1單元」。　　[0116]

[0023] <<Thermal Transfer Sheet>> Hereinafter, the thermal transfer sheet of the present invention will be described with reference to the drawings. However, the present invention can be implemented in many different forms, and is not limited to the description of the description of the implementation form exemplified below. In addition, the drawings are for a clearer description of the behavior, so compared to the actual state, the width, thickness, shape, etc. of each part have a modal representation, but it is only an example and does not limit the present invention. Explanation. In addition, in the description of this case and the drawings, the same elements as the above-mentioned drawings are attached with the same symbols, and detailed descriptions are appropriately omitted. [0024] The thermal transfer sheet of one embodiment of the present invention (hereinafter, sometimes referred to as the thermal transfer sheet of one embodiment) is as shown in Figures 1(a), (b), and 2(a), (b) As shown in the figure, on one surface of the substrate 1, the infrared absorbing material layer 2 and the color material layer 3 are arranged in the order of frames. Moreover, the thermal transfer sheet 10 of the form shown in Figure 1(a) has one color material layer 3, and the thermal transfer sheet 10 of the form shown in Figure 1(b) has multiple color material layers. (The color material layer 3Y, the color material layer 3M, and the color material layer 3C are in the form shown in the figure). In addition, the thermal transfer sheet 10 of the form shown in Figure 2(a) is on one surface of the substrate 1, showing the infrared absorbing material layer 2, the first transfer layer (5), and the color material layer 3 as the basis The structure is arranged in frame order. The thermal transfer sheet 10 of the form shown in Figure 2(b) is on one surface of the base material 1 and presents the infrared absorbing material layer 2, the first transfer layer (5), and the color material. Layer 3 and the second transfer layer (7) are arranged in the order of frames. Still, the base material 1, the infrared absorbing material-containing layer 2, and the color material layer 3 are essential components of the thermal transfer sheet 10 in one embodiment, the first transfer layer (5), the second transfer layer (7) It is an arbitrary structure of the thermal transfer sheet 10 of an embodiment. Hereinafter, each configuration will be described in detail. [0025] (Substrate) The substrate 1 is not limited in any way, and a generally known one can be appropriately selected and used in the field of the thermal transfer sheet. As an example, polyethylene terephthalate, polyethylene naphthalate, polybutylene terephthalate, polyphenylene sulfide, polyether ketone, or polyether sulfonate have high heat resistance. Polyester, polypropylene, polycarbonate, cellulose acetate, polyethylene derivatives, polyvinyl chloride, polyvinylidene chloride, polystyrene, polyamide, polyimine, polymethylpentene or ionic polymerization Stretched or unstretched films of plastics such as objects. In addition, a composite film in which two or more types of these materials are laminated can also be used. [0026] Also, on the substrate 1, corona discharge treatment, plasma treatment, ozone treatment, flame treatment, primer (also called anchor coating, adhesion promoter, easy adhesion agent) coating treatment, Pre-heat treatment, dust removal treatment, vapor deposition treatment, alkali treatment, imparting anti-static layer, etc. for easy bonding treatment. In addition, the base material 1 may contain additives such as fillers, plasticizers, colorants, and antistatic agents as necessary. The thickness of the base material 1 is not particularly limited, but it is preferably in the range of 2 μm or more and 10 μm or less. [0027] (Infrared absorbing material-containing layer) As shown in each figure, an infrared absorbing material-containing layer 2 is provided on one surface of the substrate 1 (on the upper surface of the substrate 1 in the form shown in the figure). The infrared absorbing material-containing layer 2 contains an infrared absorbing material as an essential component. In the specification of this case, the infrared absorbing material refers to a material that absorbs infrared light. [0028] That is, with the thermal transfer sheet 10 of one embodiment, the thermal transfer sheet 10 and the transfer target 100 are overlapped to melt and transfer the infrared absorbing material-containing layer 2 on the transfer target 100 , It is possible to form an image 50A containing an infrared absorbing material that cannot be visually recognized under visible light or is difficult to visually recognize under infrared light on the transferred body 100 (refer to FIG. 7). Hereinafter, an image containing an infrared absorbing material may be referred to as a "special image". In addition, the "special image" may also be referred to as an invisible image. [0029] The "infrared light region" referred to in the specification of this case means a wavelength range above 750 nm and below 2500 nm. In addition, the "visible light region" means a wavelength range greater than 400 nm and less than 750 nm. In addition, the "near-infrared light region" described later means a wavelength range of 750 nm or more and 1400 nm or less. [0030] Examples of the infrared absorbing material system include diiminium-based compounds, ammonium-based compounds, phthalocyanine-based compounds, dithiol-based organometallic complexes, cyanine-based compounds, azo-based compounds, and polymethines. Base compound, quinone compound, naphthoquinone compound, diphenylmethane compound, triphenylmethane compound, oxolene compound, carbon black, etc. The infrared absorbing material-containing layer 2 may contain one kind of these infrared absorbing materials alone, or two or more kinds of them. [0031] In particular, in the case of the infrared absorbing material-containing layer 2 containing a diiminium-based compound or a cyanine-based compound, it is used on a special image that can be obtained by melting and transferring the infrared absorbing material-containing layer 2 When the color material layer described later forms a thermal transfer image, it can be said to be an ideal infrared absorbing material in that it does not adversely affect the light resistance or plasticizer resistance of the thermal transfer image. Examples of diiminium-based compound systems include diiminium salts of bis(trifluoromethanesulfonyl)imidic acid. [0032] In addition, the infrared-absorbing material-containing layer 2 may contain a binder resin together with the above-mentioned infrared-absorbing material. Examples of binder resins include polyester resins, polyethylene resins, fluorine resins, polystyrene resins, polyacrylic resins, cellulose resins, polycarbonate resins, and polyamide resins. , Polyolefin resins such as polypropylene resins, polyvinyl alcohol resins, polyimide resins, phenol resins and polyurethane resins are generally known resins. [0033] In addition, the infrared absorbing material-containing layer 2 may also contain various additives. As an example of the additive material, a compound having a hue, etc., such as an organic pigment or an inorganic pigment, etc. can be cited. Examples of organic pigments include colored pigments such as yellow, magenta, and cyan, or hollow particles. Examples of inorganic pigments include silica, titanium oxide, titanium dioxide, zinc oxide, cerium oxide, titanium mica, muscovite, white carbon, calcium carbonate, barium sulfate, alumina white, and talc. In addition, core-shell pigments, etc., in which a core made of inorganic pigments are coated with a shell made of organic pigments, can also be used. In addition to this, organic dyes such as yellow dyes, magenta dyes, and cyan dyes can also be used. [0034] Furthermore, since the transfer body 100 on which the special image 50A is formed is ideally used in general white, the purpose is to further enhance the special image 50A when the white transfer body 100 is used. In the case of concealment, it is desirable to use white compounds such as titanium oxide and calcium carbonate as the above-mentioned additive materials. Among them, titanium oxide is particularly suitable. [0035] Still, the thermal transfer sheet 10 used in the combination of one embodiment is presented on one surface of the substrate 1, and the composition containing the infrared absorbing material layer 2 and the color material layer 3 is arranged in the order of the frame, and the infrared ray is included. When the hues of the absorbing material layer 2 and the color material layer 3 are close, the infrared absorbing material-containing layer 2 cannot be correctly detected in the thermal transfer printer, and the problem of positioning during printing cannot be correctly generated. Therefore, the infrared-absorbing material-containing layer 2 in an ideal form contains a pigment or an organic dye that is different from the color material layer 3 in hue together with the infrared-absorbing material. With the ideal form of the infrared-absorbing material-containing layer 2, the hue of the infrared-absorbing material-containing layer 2 and the color material layer 3 can be different, and the infrared-absorbing material-containing layer 2 can be correctly detected in the thermal transfer printer. [0036] The content of the aforementioned additive material is not particularly limited. As an example, it is in the range of 0.1% by mass or more and 80% by mass or less with respect to the total mass of the infrared absorbing material-containing layer 2, preferably 5 mass% or more and 40% by mass. The range below mass%. [0037] Also, instead of making the infrared-absorbing material-containing layer 2 contain a pigment or organic dye, the infrared-absorbing material-containing layer 2 is set as a layer 2A containing an infrared-absorbing material, which is different from the color of the pigment or color material layer 3. The laminated structure of the organic dye layer 2B can improve the detection accuracy of the infrared-absorbing material-containing layer 2 in the thermal transfer printer. [0038] In the case where the infrared-absorbing material-containing layer 2 has a laminated structure, the infrared-absorbing material-containing layer 2A is as shown in Fig. 6(a), and may be located closest to the substrate 1, as shown in Fig. 6 As shown in Figure (b), it can also be located farthest from the substrate 1. As shown in Figures 6(c) and (d), the infrared-absorbing material-containing layer 2 is set to include the infrared-absorbing material-containing layer 2A, In the laminated structure of the pigment-containing layer 2B and one or two or more arbitrary layers 2C, the layer 2A containing the infrared absorbing material may be located between any of the layers. The same applies to the pigment-containing layer 2B. In addition, the thermal transfer sheet 10 of the form shown in FIG. 6 may be configured to remove the first transfer layer (5). [0039] The pigment-containing layer 2B contains at least one of the organic pigments and inorganic pigments exemplified above, and additives such as binders as necessary. Examples of the adhesive system include ethylene-vinyl acetate copolymer, ethylene-acrylate copolymer, polyethylene, polystyrene, vinyl chloride resin, vinyl chloride-vinyl acetate copolymer, polyvinyl alcohol, and vinylidene chloride. Vinyl resin, acrylic resin, methacrylic resin, polyamide, polycarbonate, fluororesin, polyvinyl formal, polyvinyl butyral, acetyl cellulose, nitrocellulose, polyvinyl acetate, Polyisobutylene, ethyl cellulose or polyacetal, etc. Furthermore, various waxes such as various low-molecular-weight polyethylene, shellac wax, candelilla wax, petroleum amide, polyester wax, partially modified wax, fatty acid ester, and fatty acid amide can also be used. [0040] The thickness of the pigment-containing layer 2B is not particularly limited, but the range of 0.1 μm or more and 5 μm or less is preferable, and the range of 0.5 μm or more and 1.5 μm or less is more preferable. [0041] In addition, the above-mentioned pigment-containing layer 2B may be an organic pigment-containing layer 2B. As a layer system containing an organic dye, the color material layer 3 mentioned later can be selected suitably and used. [0042] The thickness of the infrared absorbing material-containing layer 2 is not particularly limited, but it is preferably in the range of 0.1 μm or more and 5 μm or less. When the thickness of the infrared absorbing material-containing layer 2 is set to a desired range, a special image 50A that can be sufficiently recognized by infrared light can be formed. However, when the thickness of the infrared absorbing material-containing layer 2 is too thin, the detectability tends to decrease when detecting the special image 50A formed using the infrared absorbing material-containing layer 2. On the other hand, if the thickness of the infrared absorbing material-containing layer 2 is set too thick, it is easy to cause tailing or text collapse when the infrared absorbing material-containing layer 2 is transferred to the transferred body. The tendency to produce. Still, the so-called trailing system in the specification of this case means that when the transfer layer is transferred to the transferred body, the boundary between the transfer area and the non-transfer area of the transfer layer is set as the starting point, so that the boundary exceeds the boundary. The phenomenon that the transfer layer is transferred to the non-transfer area. In addition, in the specification of this case, the so-called character collapse system means that the transferred area surrounded by the transfer area indicated by the text or held by the transfer area is transferred in the same phenomenon as the trailing, and the original is not reproduced. Phenomenon of words. [0043] The method of forming the infrared absorbing material-containing layer 2 is not particularly limited, but an infrared absorbing material-containing layer in which an infrared absorbing material, a binder resin, and various additives added as necessary are dispersed or dissolved in an appropriate solvent is prepared. With the coating liquid, the coating liquid is applied and dried on the substrate 1 or any layer provided on the substrate 1 to form it. The coating method of the coating liquid for an infrared absorbing material-containing layer is not particularly limited, and a conventionally known coating method can be appropriately selected and used. Examples of the coating method system include a gravure printing method, a screen printing method, a reverse coating method using a gravure, and the like. Moreover, other coating methods can also be used. This situation is the same with respect to the coating method of various coating liquids described later. [0044] (Release layer) In order to improve the transferability (releasability) of the infrared-absorbing material-containing layer 2, a release layer (not shown) may be provided between the substrate 1 and the infrared-absorbing material-containing layer 2. Show). Note that the release layer is a layer that remains on the side of the base material 1 when the infrared absorbing material-containing layer 2 is transferred to the body 100 to be transferred. Examples of the material of the release layer include various waxes such as silicone wax, silicone resin, resin modified by silicone, fluororesin, acrylic resin, polyvinyl alcohol, cellulose derivative resin, etc. The various resins, etc. or mixtures of these. The thickness of the release layer is usually in the range of 0.5 μm or more and 5 μm or less. [0045] (Color material layer) As shown in FIG. 1, the above-mentioned infrared absorbing material-containing layer 2 and the color material layer 3 are arranged in the order of frames on one surface of the substrate 1. The color material layer 3 contains a color material that absorbs wavelengths in the visible light region, and a binder resin. In the case where the thermal transfer image 50B formed by using the thermal transfer sheet 10 of one embodiment is a single color, it can also be formed in a layer of only one color as shown in Fig. 1 as appropriate. If the image is a full-color image, it is also possible to add a yellow color material layer 3Y containing a yellow color material, a magenta color material layer 3M containing a magenta color material, as shown in Figure 2 The cyan color material layer 3C of the cyan color material is repeatedly formed on the same surface of the substrate 1 in the order of frames. The color material system referred to in the specification of this case includes the concepts of dyes such as sublimable dyes and fluorescent dyes or pigments. [0046] With the thermal transfer sheet 10 of one embodiment, the thermal transfer sheet 10 of one embodiment is combined with the transferred body 100, and an infrared absorbing material is used on one side of the transferred body 100 The formation of the special image 50A of the layer 2 and the formation of the thermal transfer image 50B using the color material layer 3 can be obtained on one surface of the transferred body 100, and a special image 50A containing an infrared absorbing material is provided. And the printed matter 200 of the thermal transfer image 50B containing the color material. [0047] The detection system of the special image 50A of the printed matter 200 formed by using the thermal transfer sheet 10 of an embodiment can be, for example, by irradiating infrared rays to the printed matter 200, and the infrared absorbing material contained in the special image 50A can absorb The characteristics of infrared rays, the use of optical characteristics according to the absorption range of infrared rays, etc. Examples of the detector system of the special image 50A include an infrared scanner. [0048] However, when the thermal transfer image 50B formed by using the color material layer of the thermal transfer sheet is an image with high absorption for the near-infrared light region and the wavelength of the infrared light region, in other words, When the color material layer forming the thermal transfer image 50B is a color material layer with high absorption for the near-infrared light region and the wavelength of the infrared light region, it is a special image 50A using the above-mentioned infrared scanner or the like. When detecting, there will be a problem that the thermal transfer image 50B is detected together with the special image 50A, or it is formed by using a color material layer with high absorption for the wavelength of the near-infrared light region and the infrared light region The thermal transfer image 50B affects the detection of the special image 50A, and the problem of the special image 50A cannot be detected correctly. [0049] (Color material layer of the first embodiment) The color material layer 3 of the first embodiment in consideration of such points is characterized in that the maximum reflectance of the color material layer in the wavelength range of 750 nm or more and 1400 nm or less is above 50. Furthermore, the so-called maximum reflectance in the wavelength range of 750 nm or more and 1400 nm or less in the specification of this case means measuring the reflectance of the color material layer in the wavelength range of 750 nm or more and 1400 nm or less. Among the measured reflectance, This value becomes the maximum reflectance. That is, when measuring the reflectance of the color material layer, the reflectance of the color material layer may be 50% or more in any wavelength region of 750 nm or more and 1400 nm or less. [0050] With the color material layer 3 of the first embodiment, the thermal transfer image 50B formed using the color material layer 3 does not affect the detectability of the special image 50A containing infrared absorbing material. Or, the magnitude of the influence can be reduced. That is, with the thermal transfer sheet 10 of one embodiment provided with the color material layer 3 of the first embodiment, a special image 50A and a thermal transfer image 50B can be obtained, and an infrared scanner can be used. Correctly detect the printed matter of the special image 50A. [0051] Further, in the color material layer 3 of the first embodiment, the wavelength region where the maximum reflectance of the color material layer becomes 50% or more, and the wavelength range of 750 nm or more and 1400 nm or less is in the near-infrared light region The maximum reflectance of the color material layer 3 in the wavelength range of 750nm or more and 1400nm or less easily affects the detectability of the special image 50A containing infrared absorbing material. The maximum reflectance of the color material layer 3 in the infrared region is When the reflectance is set to 50% or more, the maximum reflectance of the color material layer 3 in the near-infrared light region must be set to 50% or more, otherwise the detectability of the special image 50A cannot be sufficiently improved. The color material layer 3 of the first embodiment is further in the range of greater than 1400 nm and 2500 nm or less, and there may be a wavelength region with a reflectance of 50% or more. [0052] Specifically, when the maximum reflectance of the color material layer in the wavelength range of 750 nm or more and 1400 nm or less is less than 50%, the special image 50A including infrared absorbing material is used with an infrared scanner or the like. When detecting, it becomes easy to cause a problem that the thermal transfer image 50B is detected together with the special image 50A, or the thermal transfer image 50B affects the detectability of the special image 50A, and cannot be correctly detected. Detect the problem of special image 50A. [0053] The color material layer 3 of the first embodiment preferably has a maximum reflectance of 80% or more in the wavelength range of 750 nm or more and 1400 nm or less of the color material layer. With the ideal color material layer 3 of the first embodiment, an infrared scanner or the like can be used to improve the detectability when detecting a special image 50A containing an infrared absorbing material. [0054] In addition, a thermal transfer image 50B is formed on a special image 50A including an infrared absorbing material, and the detection of the special image 50A is performed using a sensor that detects a wavelength of 830 nm. In the color material layer 3 of the first embodiment, the reflectance of the color material layer at any wavelength within the range of 750nm or more and 950nm or less is 50% or more, especially 80% or more, more preferably 750nm Above and below 950nm, the reflectance is above 50%, especially above 80%. [0055] (Method for Measuring the Reflectance of the Color Material Layer) The reflectance of the color material layer in the present specification means the reflectance measured by the following method. Using the color material layer of the object to be measured, a solid image with 255/255 gradation (energy gradation) is formed on the transferred body. Before forming a solid image, the base line of the transferred body is determined in advance. The reflectance of the solid image in the range of 750 nm or more and 1400 nm or less was measured using a reflectance measuring device. As a reflectance measuring device, an ultraviolet-visible-near-infrared spectrophotometer (UV-3100PC) manufactured by Shimadzu Corporation was used. [0056] According to the above-mentioned measurement method, in the range of 750 nm or more and 1400 nm or less, the case where the reflectance is 50% or more exists in the range of 750 nm or more and 1400 nm or less of the color material layer of the object to be measured.

With the ideal color material layer 3 of the first embodiment, the maximum reflectance in the wavelength range of 750 nm or more and 1400 nm or less can be further improved. [0061] Examples of the "1 color material" system having a maximum reflectance of 80% or more in the wavelength range of 750 nm or more and 1400 nm or less include anthraquinone dyes, cyanomethylene dyes, and the like.

In addition, a color material with a maximum reflectance of 10% or more and less than 80% in the wavelength range of 750 nm or more and 1400 nm or less may be included. This situation is the same for the color material layer 3 of the second embodiment. [0065] The content of the color material contained in the color material layer 3 of the first embodiment is not particularly limited, and can be suitably based on the required image density of the thermal transfer image 50B or the content of the binder resin described later. set up. As an example, the content of the color material (the total content of all color materials) is in the range of 5 mass% or more and 300 mass% or less with respect to the total mass of the binder resin. This situation is the same for the color material layer 3 of the second embodiment described later.

In the color material layer 3 of the embodiment, the color material cannot be sufficiently maintained, and the preservability tends to decrease. Therefore, the content of the binder resin with respect to the total mass of the color material layer 3 of the first embodiment is preferably 20% by mass or more. The upper limit of the content of the binder resin is not particularly limited, and it can be appropriately set according to the content of the color material or any additional material. This situation is the same for the color material layer 3 of the second embodiment described later.

[0069] The method for forming the color material layer 3 of the first embodiment is not particularly limited, and it is prepared to dissolve or disperse the binder resin, the color material, the additives added as necessary, or the release agent in an appropriate solvent. The coating liquid for the color material layer of is formed by coating and drying the coating liquid on the substrate 1 or any layer provided on the substrate 1. The thickness of the color material layer 3 is generally in the range of 0.2 μm or more and 2.0 μm or less. This situation is the same for the color material layer 3 of the second embodiment described later. [0070] (Color material layer of the second embodiment) The color material layer 3 of the second embodiment contains a "color material of 1" with a maximum reflectance of 80% or more in the wavelength range of 750 nm or more and 1400 nm or less, and In (1) does not contain "other color materials" with a maximum reflectance of less than 10% in the wavelength range of 750nm or more and 1400nm or less, or (2) contains the maximum reflectance in the wavelength range of 750nm or more and 1400nm or less In the case of "other color materials" less than 10%, the content is also less than 15% by mass relative to the total mass of the color materials.

[0072] The color material layer 3 of the second embodiment may also contain color materials other than the above-mentioned "1 color material" and "other color materials". Specifically, it may contain a color material having a wavelength of 750 nm or more and 1400 nm or less. Color materials with a maximum reflectance of more than 10% and less than 80% in the range. In this case, it is desirable that the content of "1 color material" with respect to the total mass of the color material is 85% by mass or more.

[0074] In the above-mentioned series as "color material of 1" and "other color materials", the description will be given focusing on the color material contained in the cyan color material layer, but regarding the yellow color material layer and the magenta color material layer The situation is the same. [0075] Furthermore, when a plurality of color material layers with different hues are arranged in the order of the frame on the base material 1, at least one of the plurality of color material layers is the color material layer of the first embodiment and the second embodiment described above. It is desirable that all the color material layers are the color material layers of the first embodiment and the second embodiment described above. [0076] In the above system, the color material layer used in the sublimation type thermal transfer method is taken as an example for description, but it can also be changed to these color material layers 3, or together with this, the color material layer 3 Set as a hot melt ink layer used in a hot melt type thermal transfer method. The hot-melt ink layer contains a binder resin and a coloring agent as a color material. [0077] In this case, in the color material layers of the first and second embodiments described above, the description of the color material layer may be replaced with a hot melt ink layer, and the description of the color material may be replaced with a coloring agent. [0078] The color material layer 3 of the second embodiment contains the above-mentioned "color material of 1" and "other color materials" when the maximum reflectance in the wavelength range of 750 nm or more and 1400 nm or less is measured by the following method value. [0079] (Method for measuring the reflectance of the color material contained in the color material layer in the wavelength range of 750 nm or more and 1400 nm or less) In this specification, the reflectance of the color material contained in the color material layer means that Reflectance measured by the following method. A thermal transfer sheet having a color material layer is prepared, and the color material contained in the color material layer is specified using various analysis methods. After the color material is specified, the color material layer coating liquid is adjusted so that the DB ratio ("specific color material"/binder resin) becomes "1", and the coating liquid is applied and dried on the base material. On the substrate, a sample of a thermal transfer sheet with a color material layer containing the color material to be measured is prepared. Still, polyvinyl acetal resin (S-LEC (registered trademark) KS-5 Sekisui Chemical Industry Co., Ltd.) is used as the binder resin. Using a sample of the prepared thermal transfer sheet, a solid image is formed on the transfered body by the method described in the above "Method for Measuring the Reflectance of the Color Material Layer", and the wavelength of the solid image is measured at 750nm Reflectance in the range above and below 1400nm. Among the measured reflectances, the largest value is used as the maximum reflectance of the color material contained in the color material layer. [0080] (Color material undercoating layer) Between the base material 1 and the color material layer 3, a color material undercoating layer (not shown) whose purpose is to improve the adhesion between the base material 1 and the color material layer 3 can also be provided. Show). [0081] There is no limitation on the color material base coat, and a previously known color material base coat can be appropriately selected and used in the field of thermal transfer sheets. As an example, the color material primer layer is composed of a resin material. Examples of the resin material system constituting the color material primer layer include polyester resins, polyvinylpyrrolidone resins, polyvinyl alcohol resins, polyacrylate resins, polyvinyl acetate resins, and polyurethanes. Ester resins, styrene acrylate resins, polypropylene amide resins, polyamide resins, resins such as polyvinyl acetal or polyvinyl butyral. In addition, the color base coat layer may contain various additives such as organic particles or inorganic particles together with these resin components. [0082] There is no particular limitation on the method of forming the color material undercoating layer, and the color material undercoating layer can be prepared by dissolving or dispersing the resin components exemplified above and the additives added as necessary in an appropriate solvent. The coating liquid is applied and dried on the substrate 1 to form it. The thickness of the color base coat is not particularly limited, but it is usually in the range of 0.02 μm or more and 1 μm or less. [0083] (First transfer layer) As shown in Figure 2(a), the above-mentioned infrared absorbing material-containing layer 2, the first transfer layer (5), and the above-mentioned Color material layer 3. The first transfer layer (5) is configured to be peelable from the base material 1. The first transfer layer (5) is directly transferred to the transferred body 100 by means of thermal transfer, or transferred to the transferred body 100 where the special image 50A is formed by the infrared absorbing material layer 2 The upper layer. [0084] With the thermal transfer sheet 10 of one embodiment provided with the first transfer layer (5), a special image 50A containing an infrared absorbing material is formed on the transferred body 100, and further, a special image 50A is shown here. The first transfer layer (5) can be formed on the image 50A. That is, the special image 50A can be covered by the first transfer layer (5). Thereby, various problems caused by the special image 50A being exposed to the surface can be suppressed. For example, the special image 50A can be suppressed from disappearing due to an external impact or the like. Furthermore, on the first transfer layer (5), the thermal transfer image 50B is formed by the color material layer 3 of the above-mentioned first embodiment and the second embodiment. The printed matter 200 of the printed image 50B imparts a three-dimensional effect. [0085] In the case where the thermal transfer image 50B is formed on the first transfer layer (5) by the sublimation type thermal transfer method, the first transfer layer (5) includes at least the receiving layer 5A, showing only A single-layer structure composed of the receiving layer 5A, or a laminate structure in which the receiving layer 5A and the other layers are laminated in this order from the substrate 1 side (refer to Figure 2(a)). The reason why the layer that is closest to the substrate 1 among the layers constituting the first transfer layer (5) is set as the receiving layer 5A is because when the first transfer layer (5) is transferred onto the body to be transferred, The receiving layer 5A is positioned on the outermost surface. [0086] "Receptive layer" The material of the receptive layer 5A is not particularly limited, but it is desirable to use a binder resin that is easily dyed by the color material contained in the color material layer 3.

Polyester resins such as ethylene phthalate and polybutylene terephthalate, polystyrene resins, polyamide resins, ionomers, cellulose resins, etc. The receiving layer 5A may contain one kind of these binder resins alone, or two or more kinds. In addition, copolymers formed by copolymerizing two or more monomers of these binder resins can also be used. Examples of such copolymers include copolymers of olefins such as ethylene or propylene and other vinyl monomers. Among them, the cellulosic resin system can sufficiently satisfy the transferability of the receiving layer 5A of the layer located at the transfer interface. In the case of increasing the energy applied to the thermal transfer sheet 10, it is also suitable for the first layer including the receiving layer 5A. 1 The transfer layer (5) is ideal as a material for the receiving layer 5A in terms of satisfying the transferability of the transfer layer (5). In addition, the vinyl chloride-vinyl acetate copolymer is ideal as a material for the receiving layer 5A in terms of dye adhesion of the receiving layer 5A or improving the releasability of the receiving layer 5A and the color material layer 3. [0087] Examples of the cellulose resin system include cellulose acetate resin, cellulose acetate butyrate resin, cellulose acetate propionate resin, nitrocellulose resin, cellulose acetate, and the like. [0088] Since the receiving layer 5A suppresses thermal fusion with the color material layer 3 during printing, it may also contain a release agent. Examples of mold release agents include solid waxes such as polyethylene wax, amide wax, Teflon (registered trademark) powder, fluorine or phosphate ester surfactants, silicone oils, reactive silicone oils, hardening silicone oils, etc. Modified silicone oil, and various polysilicone resins, etc. [0089] The receiving layer 5A is a coating solution for receiving layer that can be prepared by dispersing or dissolving additives such as the above-mentioned binder resin, a mold release agent added as necessary in an appropriate solvent, and then coating and drying the coating solution on the substrate. The material 1 or any layer provided on the substrate 1 is formed. The thickness of the receiving layer 5A is not particularly limited, but it is usually in the range of 0.3 μm or more and 10 μm or less. [0090] "Heat Sealing Layer" In order to improve the adhesion between the transferred body 100 and the first transfer layer (5), as shown in Figure 2(a), the first transfer layer (5) ) Is a laminated structure in which the receiving layer 5A and the heat-sealing layer 5C are laminated in this order from the base material 1 side. As the material of the heat-sealing layer 5C, it is desirable that the adhesiveness of the material to be transferred 100 is good.

[0108] (Thermal transfer sheet of other embodiments) Above, a specific example of the thermal transfer sheet of one embodiment was described. However, the thermal transfer sheet 10 of other embodiments is presented on one surface of the substrate. , The infrared absorbing material-containing layer 2 is not provided, and the color material layer 3 of the above-mentioned first embodiment or the color material layer of the second embodiment is already provided. The thermal transfer sheet 10 of another embodiment is a thermal transfer sheet used in advance to form a thermal transfer image 50B on a transfer target body on which a special image 50A has been formed. With the thermal transfer sheet 10 of another embodiment, the color material layer 3 of the first embodiment or the color material layer of the second embodiment is used in advance on the transferred body on which the special image 50A has been formed 3. When the thermal transfer image 50B is formed, the printed matter 200 having the special image 50A and the thermal transfer image 50B can be obtained, and the special image 50A can be accurately detected by using an infrared scanner or the like. [0109] The thermal transfer sheet 10 of other embodiments can be set on one surface of the substrate 1, together with the color material layer 3 of the first embodiment or the color material layer of the second embodiment, in frame order The configuration of a layer different from that of the infrared absorbing material-containing layer 2 is provided. Examples of a layer system different from the infrared absorbing material-containing layer 2 include the above-mentioned first transfer layer (5) or second transfer layer (7). [0110] <Configuration Example of Thermal Transfer Sheet> FIGS. 3 to 5 are schematic cross-sectional views showing an example of the configuration of a thermal transfer sheet used in a combination of an embodiment. [0111] The thermal transfer sheet 10 in the form shown in Figure 3(a) is on one surface of the substrate 1, and the infrared absorbing material layer 2, the first transfer layer (5), and the yellow color are arranged in the order of the frame. Material layer 3Y, magenta color material layer 3M, cyan color material layer 3C, second transfer layer (7), yellow color material layer 3Y, magenta color material layer 3M, cyan color material layer 3C, second transfer layer (7). When the thermal transfer sheet 10 of the form shown in Figure 3 is set to "1 panel" for each layer, from the upstream side of the printing (the form shown in the figure is on the left side of the drawing), "6 panels" are used for the The panel used to form an image on one side of the transfer body 100 (form the image of the first screen), and the remaining "4 panels" are used to form an image on the other side of the transfer body 100 (form the first screen). 2 screen image) and use the panel. However, in the case where the transferred body 100 does not have a receiving layer, the first transfer layer (5) can be provided between the second transfer layer (7) and the yellow color material layer 3Y, and the first transfer layer (5) can be provided by the first transfer layer (7). The "5 panel" composed of the printing layer (5), the yellow color material layer 3Y, the magenta color material layer 3M, the cyan color material layer 3C, and the second transfer layer (7) is on the other side of the transferred body 100 An image is formed on the side. In addition, as shown in Fig. 3(b), the "6 panel" and "4 panel" in Fig. 3(a) can be exchanged. Moreover, it can also be set as the structure (not shown) which removes the 2nd transfer layer (7). In addition, in the form shown in Figure 3(c), the infrared absorbing material layer 2, the first transfer layer (5), the yellow color material layer 3Y, the magenta color material layer 3M, the cyan color material layer 3C, When the second transfer layer (7), the yellow color material layer 3Y, the magenta color material layer 3M, the cyan color material layer 3C, and the second transfer layer (7) "10 panel" are set to "1 unit", this "1 unit" is set repeatedly. Hereinafter, the case of the image formed on one side of the transfer body 100 is referred to as the "image of the first screen", and the case of the image formed on the other side of the transfer object is referred to as the "second screen image". 2 screen image". [0112] However, when the assembly of each "panel" is set to "1 unit" for the alignment or heading of printing, it is performed in units of "1 unit", and "1 unit" is necessary to form other "1 unit". The arrangement of "panel" is the same as that of "1 unit". That is, in the form shown in Fig. 3, the "6 panels" used when the "image of the first screen" is formed on one side of the transferred body 100 individually cannot be used. The "4 panel" used to form the "image of the second screen" on the other side is set to "1 unit". It is necessary to set the "10 panel" that combines "6 panels" and "4 panels" to "1 unit" . However, as the number of "panels" that make up "1 unit" increases, there is a problem that the design load of the thermal transfer printer used to detect each layer increases, and the "number of panels" that make up "1 unit" is less optimal. [0113] Thus, the thermal transfer sheet 10 of the form shown in FIG. 4 is set on one surface of the substrate 1, and consists of an infrared absorbing material layer 2, a first transfer layer (5), a yellow color material layer 3Y, When the assembly composed of the magenta color material layer 3M, the cyan color material layer 3C, and the "6 panels" of the second transfer layer (7) is set to "1 unit", the "1 unit" is repeatedly installed. That is, in contrast to the form shown in Fig. 3, the panel used to form the "image of the first screen" on one side of the body to be transferred is composed of "6 panels", and for the purpose of being transferred If the panel used to form the "image of the second screen" on the other side of the body is composed of "4 panels", the form shown in Figure 4 will be used to form the "image of the first screen" And the panel of the "image of the second screen" are composed of "6 panels" together, so that this "6 panel" is set to "1 unit" and the number of panels constituting "1 unit" is reduced. [0114] On the other hand, in the form shown in FIG. 4, the "image of the first screen" is set to include the image of the special image 50A, and the "image of the second screen" is set to not include Particularly in the case of the image of the image 50A, since the number of panels constituting "1 unit" is reduced, it is necessary to include the infrared absorbing material-containing layer 2 in all "1 unit", which causes a problem of increased waste. [0115] Thus, the thermal transfer sheet 10 of the form shown in FIG. 5 is set on one surface of the substrate 1, and consists of an infrared absorbing material layer 2, a first transfer layer (5), a yellow color material layer 3Y, When the assembly composed of the magenta color material layer 3M, the cyan color material layer 3C, and the "6 panels" of the second transfer layer (7) is set to "1 unit", the image provided on the first screen and the second The two-screen image forming panel is integrated as a "panel" with the length of the two-screen. In the form shown in the figure, the yellow color material layer 3Y, the magenta color material layer 3M, and the cyan color material layer 3C are individually "panels" with a length of 2 screens. That is, one color material layer is used to form the image of the first screen and the image of the second screen. With the thermal transfer sheet 10 in this form, the length of the "panel" used for the layer of the image formed on one side and the other side of the body to be transferred is set to the length of 2 screens. If the "panel" of the layer of the image formed on either side is set to the length of one screen, waste due to the "panel" that is not used can be suppressed. For example, with the thermal transfer sheet 10 of the form shown in Fig. 5, "1 unit" is used to form the image of the first screen on one surface of the transfer body 100, and then the transfer body 100 Turn it upside down, unwind the thermal transfer sheet 10 at the same time, and reuse the previously used "1 unit" to form an image of the second screen on the other side of the transfer body 100. The form shown in Fig. 5 is for forming the image of the first screen and the image of the second screen for the yellow color material layer 3Y, magenta color material layer 3M, and cyan color material layer 3C. So the "panel" length is set to the length of 2 screens, but other layers can also be set, for example, the "panel" of the first transfer layer (5) or the second transfer layer (7) can be long It is the length of 2 screens. Also, "1 unit" can be set repeatedly. [0116] <<Method of manufacturing printed matter>> Next, referring to FIGS. 7-9, a method of manufacturing a printed matter according to one embodiment of the present invention (hereinafter referred to as a method of manufacturing printed matter of an embodiment) will be described. . [0117] (The manufacturing method of the printed matter of the first embodiment) The manufacturing method of the printed matter of the first embodiment is a method of manufacturing a printed matter using the thermal transfer sheet 10 and the transferred body 100, and is characterized in that it contains The step of preparing the transferred body of the printed body 100, and the preparation on one surface of the substrate 1, the infrared absorbing material-containing layer 2, and the color material layer 3 containing the color material, are thermal transfers arranged in the order of frames. The thermal transfer sheet preparation steps of the printing sheet 10, and the method shown in Figure 7(a) and Figure 8(a), on one surface of the transfer body 100, transfer the infrared rays of the thermal transfer sheet The special image forming step of forming the special image 50A containing the infrared absorbing material by absorbing the material layer 2 is similar to the method shown in Fig. 7(b) and Fig. 8(b) on one side of the transferred body 100 Above, the thermal transfer image forming step of thermally transferring the color material layer 3 of the thermal transfer sheet 10 to form a thermal transfer image 50B; the color material layer 3 of the thermal transfer sheet 10 has a wavelength above 750 nm and 1400 nm The maximum reflectance in the following range is 50% or more. That is, as the thermal transfer sheet 10, it is characterized by using the thermal transfer sheet 10 of one embodiment provided with the color material layer 3 of the above-mentioned first embodiment. [0118] According to the method of manufacturing a printed matter of the above-mentioned embodiment, a special image 50A having an infrared absorbing material containing a thermal transfer sheet 10 and a thermal transfer image 50B containing a color material can be obtained. The scanner, etc., can accurately detect the printed matter 200 of the special image 50A. Hereinafter, each step will be described in detail. [0119] (Step of Preparing the Transferred Body) The transferred body 100 prepared in this step can be used as it is, and the transfer target 100 described in the combination of the above-mentioned embodiment can be used as it is. Omitted. [0120] (Step of preparing a thermal transfer sheet) The thermal transfer sheet 10 prepared in this step can be used as it is with the thermal transfer sheet 10 described in the combination of the above-mentioned one embodiment. The detailed description here is Omitted. [0121] (Special image forming step) In this step, the thermal transfer sheet 10 and the object to be transferred 100 are opposite to the infrared absorbing material-containing layer 2 of the thermal transfer sheet 10 and the object to be transferred 100. As shown in Fig. 7(a) and Fig. 8(a), the infrared absorbing material-containing layer 2 of the thermal transfer sheet 10 is melted and transferred on one surface of the transferred body 100 to form a special Image 50A steps. The special image 50A is not particularly limited. For example, a two-dimensional code including image information of the thermal transfer image 50B described later can be cited. As the thermal transfer printer system used for the formation of the special image 50A, the transfer of the first transfer layer (5), and the formation of the thermal transfer image 50B, one with a thermal head, etc. can be suitably selected. The heating means is used by a previously known list machine. Moreover, in addition to the method using a heating means such as a thermal head, for example, a thermal embossing method or a thermal roller method can be used. However, the formation of the special image 50A can be performed using a thermal melting type thermal transfer method. The so-called thermal melting type thermal transfer method is a method in which a color material layer that has been melted and softened is transferred to a transferred body to form an image by applying energy corresponding to image information from a heating means. [0122] (Thermal Transfer Image Forming Step) In this step, the thermal transfer sheet 10 and the object to be transferred 100 are made to oppose the color material layer 3 of the thermal transfer sheet 10 and the surface of the object to be transferred 100. To transfer the color material contained in the color material layer 3 by overlapping the method, the step of forming a thermal transfer image 50B on the transferred body 100 as shown in Fig. 7(b) and Fig. 8(b) . Through this step, a printed matter 200 in which a special image 50A and a thermal transfer image 50B are formed on one surface of the to-be-transferred body 100 is obtained. [0123] The form shown in Fig. 8(b) forms a thermal transfer image 50B in such a way as to overlap at least a part of the special image 50A, but it may also be as shown in Fig. 7(b), especially The image 50A and the thermal transfer image 50B are not overlapped. In addition, the thermal transfer image 50B can also be formed in such a way as to cover the entire surface of the special image 50A. [0124] Furthermore, after the thermal transfer image 50B is formed on the body 100 to be transferred, a special pattern may be formed on the thermal transfer image 50B by overlapping with at least a part of the thermal transfer image 50B. Like 50A (not shown). [0125] The color material layer 3 of the thermal transfer sheet 10 contains a sublimable dye as a color material, and when the thermal transfer image 50B is formed using the sublimation type thermal transfer method, the transferred body 100 has The receiving layer for receiving sublimation dyes is ideal. [0126] (Second transfer layer transfer step) Also, as shown in Figure 7(c) and Figure 8(c), after the formation of the special image 50A and the thermal transfer image 50B , The second transfer layer transfer step of transferring the second transfer layer (7) is performed in a manner of covering the special image 50A and the thermal transfer image 50B. The second transfer layer transfer step is an arbitrary step in the manufacturing method of the printed matter of one embodiment. The transfer system of the second transfer layer (7) is shown in Figure 2(b), Figure 3 to Figure 5. It can also be performed by using the thermal transfer sheet 10 with the second transfer layer (7) It can also be performed using another thermal transfer sheet (protective layer transfer sheet, etc.) different from the thermal transfer sheet 10 prepared above. [0127] (Additional thermal transfer image forming step) In addition, the thermal transfer sheet 10 shown in FIGS. 3 to 5 is used, prior to the above-mentioned various steps, or, after performing the above-mentioned various After the step, as shown in Fig. 7(d) and Fig. 8(d), another thermal transfer image 50C can also be formed on the other surface of the to-be-transferred body 100. In this case, the other side of the transferred body 100 does not have a receiving layer, and the thermal transfer image 50C is formed by the sublimation thermal transfer method before the thermal transfer image 50C is formed. The other surface of the transferred body 100 may also include a step of transferring the receiving layer. The transfer system of the receiving layer may also be performed by transferring the first transfer layer (5) as described later, or may be performed using other thermal transfer sheets. According to the manufacturing method of a printed matter of one embodiment including another thermal transfer image forming step, a printed matter having thermal transfer images formed on both sides can be obtained. In addition, instead of the thermal transfer image 50C, or together with the thermal transfer image 50C, a special image 50A can be formed on the other surface of the transferred body 100. [0128] (The manufacturing method of the printed matter of the second embodiment) The manufacturing method of the printed matter of the second embodiment is a method of manufacturing a printed matter using the thermal transfer sheet 10 and the transferred body 100, and is characterized in that it contains The step of preparing the transferred body of the printed body 100, and the preparation on one surface of the substrate 1, the infrared absorbing material-containing layer 2, and the color material layer 3 containing the color material, are thermal transfers arranged in the order of frames. The thermal transfer sheet preparation step of the printing sheet 10, and as shown in Figure 9(a), on one surface of the transfer body 100, the infrared absorbing material-containing layer 2 of the thermal transfer sheet is transferred to form a layer containing The special image forming step of the special image 50A of the infrared absorbing material, and the transfer layer transfer of the first transfer layer (5) of the thermal transfer sheet 10 as shown in Figure 9(b) Step, and as shown in Figure 9(c), on the first transfer layer (5), thermally transfer the color material layer 3 of the thermal transfer sheet 10 to form the thermal transfer image 50B In the printing image forming step, the color material layer 3 of the thermal transfer sheet 10 has a maximum reflectance of 50% or more in the wavelength range of 750 nm or more and 1400 nm or less. That is, as the thermal transfer sheet 10, it is characterized by using the thermal transfer sheet 10 of one embodiment provided with the color material layer 3 of the above-mentioned first embodiment. [0129] With respect to the manufacturing method of the printed matter of the above-mentioned first embodiment, the special image 50A and the thermal transfer image 50B are directly formed on the transfer body 100 with the special image 50A and the thermal transfer image 50B. It is carried out in a contiguous manner (refer to Fig. 8), or, in terms of forming a special image 50A and a thermal transfer image 50B side by side on the same surface of the transferred body 100 (refer to Fig. 7), The manufacturing method of the printed matter of the second embodiment is to transfer the first transfer layer (5) on the special image 50A, and then form the thermal transfer image 50B on the transferred first transfer layer (5). In point, the manufacturing method of the printed matter of the first embodiment is different from the manufacturing method of the printed matter of the second embodiment, and the other points are the same. [0130] (First transfer layer transfer step) In this step, the thermal transfer sheet 10 and the transferred body 100 on which the special image 50A has been formed are combined with the first transfer layer (5) of the thermal transfer sheet 10 ) Is overlapped with the face of the transferred body 100 facing each other. As shown in Figure 9(b), the thermal transfer sheet 10 is melted and transferred on the transferred body 100 on which the special image 50A has been formed. The step of the first transfer layer (5). The first transfer layer (5) may be transferred to the area where the thermal transfer image 50B described later is formed, and the transfer area may be the entire surface of one surface of the transferred body 100, or may be transferred A part of one surface of the body 100 (the shape shown in the figure is the entire surface of one surface of the transferred body 100). [0131] In addition, the first transfer layer (5) may be transferred to a position that does not overlap with the special image 50A. In addition, from the viewpoint of protection of the special image 50A, it is desirable to transfer the first transfer layer (5) so as to cover the special image 50A. [0132] In addition, the method of manufacturing a printed matter of the second embodiment may include any of the steps described in the method of manufacturing a printed matter of the above-mentioned first embodiment (refer to Figures 9(d) and (e)) . [0133] In addition, in the above-mentioned first embodiment and the second embodiment of the method of manufacturing printed matter, the thermal transfer sheet used in the formation of the printed matter is used to set the color material layer of the thermal transfer sheet 10 at a wavelength of 750 nm The above description will focus on the case where the maximum reflectance in the range of 1400 nm or less is 50% or more. That is, the thermal transfer sheet 10 is a thermal transfer sheet 10 provided with the color material layer 3 of the first embodiment. The case will be described as the center, but instead of this, a thermal transfer sheet provided with the color material layer 3 of the second embodiment described above may be used. [0134] <<Thermal transfer printer>> Next, the thermal transfer printer of one embodiment of the present invention (hereinafter referred to as the thermal transfer printer of one embodiment) will be described.
