Description

Technical Field

[0001] The present disclosure relates to an intermediate transfer medium, an intermediate transfer medium with a release member, a combination of an intermediate transfer medium and a thermal transfer sheet, a combination of an intermediate transfer medium, a thermal transfer sheet, and a transfer object, a printed matter, and a method for manufacturing the printed matter.

Background Art

[0002] Conventionally, as a method for manufacturing a printed matter by a thermal transfer method, for example, a method of using a thermal transfer sheet and transferring an image from the thermal transfer sheet to a transfer object is known. Further, a method of using a thermal transfer sheet and an intermediate transfer medium, transferring an image from the thermal transfer sheet to the intermediate transfer medium, and then re-transferring the image from the intermediate transfer medium to the transfer object is also known.

[0003] In recent years, with the diversification of the uses of printed matters, the demand for forming an image on an arbitrary transfer object has been increasing. In the former method described above, since the image is directly transferred to the transfer object, the transfer object to be used is limited. On the other hand, in the latter method described above, since an intermediate transfer medium is used, the transfer object is not restricted.

[0004] By the way, a method for manufacturing a printed matter by a thermal transfer method can transfer an image well to a transfer object having high surface smoothness. However, for a transfer object having low surface smoothness, since it is difficult for the image to be transferred to the concave portions of the irregularities on the surface of the transfer object, blurring, white spots, or unclear edges of the image may occur, resulting in a problem of deterioration in printing quality.

[0005] Therefore, Patent Document 1 proposes a heat-sensitive transfer material in which a heat-transferable ink layer containing a heat-meltable binder, a colorant, and a thermally decomposable foaming agent is formed on a support. Furthermore, Patent Document 2 proposes a heat-transfer recording medium in which a foaming agent layer containing a foaming agent is provided between a support layer and an ink layer. In these technologies, during heat transfer, heating causes the thermally decomposable foaming agent contained in the heat-transferable ink layer to decompose and generate gas, or the foaming agent contained in the foaming agent layer between the support layer and the ink layer to decompose and expand, pressing the ink layer against the object to be transferred, thus making it possible to transfer ink to recesses on the surface of the object to be transferred. In addition, in the above technologies, the layer containing the foaming agent is also transferred to the object to be transferred.

[0006] Furthermore, Patent Document 3 proposes a thermal transfer recording medium in which a foaming agent-containing layer, a heat-melt release layer, and a heat-melt coloring layer are laminated on a substrate in this order. In this technology as well, during thermal transfer, the foaming agent contained in the foaming agent-containing layer foams or expands due to heating, pressing the heat-melt coloring layer against the object to be transferred, thus making it possible to transfer ink to recesses on the surface of the object to be transferred. In addition, in the above technology, the layer containing the foaming agent remains on the substrate during thermal transfer. [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Japanese Patent Application Publication No. 59-201893 [Patent Document 2] Japanese Patent Application Publication No. 60-82389 [Patent Document 3] Japanese Patent Publication No. 2005-161799 [Overview of the Initiative] [Problems that the invention aims to solve]

[0008] In the thermal transfer method for manufacturing printed materials, a thermal transfer printer is used. In a thermal transfer printer, a thermal transfer sheet and the object to be transferred are placed on top of each other, and the sheet is passed between a thermal head and a platen roller. The thermal head then locally heats the thermal transfer sheet, thereby transferring the image to the object to be transferred.

[0009] In the above technology, a foaming agent is foamed or expanded during thermal transfer. However, in thermal transfer printers, the heat transfer sheet is heated locally while transporting the thermal transfer sheet and the object to be transferred, resulting in a short heating time. Furthermore, the thermal energy from the thermal head diffuses from the object to be transferred. Therefore, it is difficult to sufficiently foam or expand the foaming agent. Consequently, even when utilizing the foaming or expansion of the foaming agent, it remains difficult to transfer ink to the depressions on the surface of the object to be transferred if the surface has significant irregularities.

[0010] This disclosure has been made in view of the above-mentioned problems, and its main purpose is to provide an intermediate transfer medium that has good transferability even to a transfer target with low surface smoothness. [Means for solving the problem]

[0016] Another embodiment of the present disclosure provides a print comprising a transfer surface and a transfer layer having an image, wherein the transfer surface is a textile and the arithmetic mean height of the side of the transfer layer opposite to the transfer surface is 1.0 μm or more and 200 μm or less.

[0017] Another embodiment of the present disclosure provides a print comprising a body to be transferred and a transfer layer having an image, wherein Sa1 is the arithmetic mean height of the surface of the body to be transferred in a region where the transfer layer is not disposed, and Sa2 is the arithmetic mean height of the side of the transfer layer opposite to the body to be transferred, such that Sa2 / Sa1 ≥ 0.05.

[0021] The embodiments will be described below with reference to the drawings and other figures. However, this disclosure can be implemented in many different ways and should not be limited to the embodiments described below. In addition, the drawings may schematically represent the width, thickness, and shape of each part compared to the actual form in order to make the explanation clearer, but this is merely an example and should not be interpreted as limiting.

[0022] In this specification, when describing a manner in which one member is placed on another member, the term "above" or "below" includes, unless otherwise specified, both cases: when the other member is placed directly above or directly below the member so as to be in contact with it, and when the other member is placed above or below the member via yet another member. Similarly, in this specification, when describing a manner in which one member is placed on the surface of a member, the term "on the surface" includes, unless otherwise specified, both cases: when the other member is placed directly above or directly below the member so as to be in contact with it, and when the other member is placed above or below the member via yet another member.

[0023] The following describes in detail the intermediate transfer medium, the combination of the intermediate transfer medium and the heat transfer sheet, the combination of the intermediate transfer medium, the heat transfer sheet and the object to be transferred, the printed object, and the method for manufacturing the printed object.

[0024] A. Intermediate transfer medium The intermediate transfer medium in this disclosure comprises, in this order, a substrate, a foaming layer containing a foaming agent, and a transfer layer. In the intermediate transfer medium in this disclosure, the foaming layer and the transfer layer are detachable, and the foaming agent is in an unfoamed state. That is, the foaming agent foams when the transfer layer is transferred to the object to be transferred.

[0025] Figure 1 is a schematic cross-sectional view illustrating an intermediate transfer medium in this disclosure. As shown in Figure 1, the intermediate transfer medium 10 comprises a substrate 1, a foamed layer 2 containing a foaming agent, and a transfer layer 3, with the thickness direction D T The elements are in this order. The intermediate transfer medium in this disclosure is a transfer sheet before an image is formed on the transfer layer, and is an image-forming sheet.

[0026] Figures 2(a) to 2(c) and 3(a) to 3(b) are process diagrams illustrating a method for manufacturing a printed object using an intermediate transfer medium in this disclosure. First, as shown in Figure 2(a), an intermediate transfer medium 10 is prepared. The intermediate transfer medium 10 is the same as the intermediate transfer medium 10 shown in Figure 1 above. Next, as shown in Figure 2(b), an image 25 is formed on the surface of the transfer layer 3 of the intermediate transfer medium 10. The image 25 may be formed on the surface of the transfer layer 3, or it may be formed by the migration of a colorant into the transfer layer 3. At this time, the foaming agent in the foamed layer 2 is in an unfoamed state, and the foamed layer 2 is not expanded. Next, as shown in Figure 2(c), the surface of the transfer layer 3 on which the image 25 of the intermediate transfer medium 10 is formed is placed opposite the surface of the object to be transferred 51. Subsequently, as shown in Figure 3(a), heat and pressure are applied to expand the foamed layer 2, and the transfer layer 3 on which the image 25 of the intermediate transfer medium 10 is formed is transferred to the surface of the object to be transferred 51. At this time, the foaming agent in the foamed layer 2 foams, and as the foamed layer 2 expands, the transfer layer 3 on which the image 25 of the intermediate transfer medium 10 is formed is pressed against the object to be transferred 51, so that the transfer layer 3 on which the image 25 is formed is pressed into the recesses of the uneven surface of the object to be transferred 51. This allows the transfer layer 3 on which the image 25 is formed to be transferred to the recesses of the uneven surface of the object to be transferred 51. As described above, the image 25 may be formed on the surface of the transfer layer 3, or it may be formed by the transfer of a colorant into the transfer layer 3, but the colorant is not transferred to the object to be transferred 51. Next, as shown in Figure 3(b), the substrate 1 and the expanded foamed layer 2 are peeled off from the transfer layer 3 that has been transferred to the object to be transferred 51. As a result, the expanded foamed layer 2 and the transfer layer 3 are separated, and only the transfer layer 3 is transferred to the object to be transferred 51. In this way, the intermediate transfer medium 10 is peelable between the foamed layer 2 and the transfer layer 3. Furthermore, the foaming agent used in the foamed layer 2 is appropriately selected to foam when the transfer layer 3 is transferred to the transfer target 51. Note that the foaming agent is not selected to foam before or during image formation on the transfer layer 3.

[0027] Figures 16(a) to 16(c) show an example of using a conventional heat transfer sheet 110 having a foamed layer 102 and a colorant layer 122 sequentially on one side of a substrate 101. In the heat transfer sheet 110, the colorant layer 122 is a melt-transfer type colorant layer that is transferred itself. First, as shown in Figures 16(a) to 16(b), the colorant layer 122 of the heat transfer sheet 110 is heat-transferred onto the object to be transferred 151, and at the same time, the foamed layer 102 of the heat transfer sheet 110 is expanded. Next, as shown in Figure 16(c), the expanded foamed layer 102a and the substrate 101 are peeled off from the colorant layer 122 transferred to the object to be transferred 151. During heat transfer, although not shown, only the area to which the colorant layer 122 of the heat transfer sheet 110 is transferred is locally heated by a thermal head. In this case, the heating temperature is high and the heating time is short. Due to the short heating time, sufficient heat cannot be applied to the heat transfer sheet 110, making it difficult to fully expand the foamed layer 102. Furthermore, if the foamed layer 102 does not expand sufficiently, the force with which the colorant layer 122 is pressed against the transfer target 151 weakens. As a result, the colorant layer 122 is not pressed into the recesses of the uneven surface of the transfer target 151, and is only transferred to the protruding parts of the uneven surface of the transfer target 151. Consequently, in the printed object 150, blurring or white spots may occur in the image formed by the heat transfer of the colorant layer 122, or the edges of the image may become unclear.

[0028] In contrast, when manufacturing a print using the intermediate transfer medium in this disclosure, as described above, an image is formed on the surface of the transfer layer of the intermediate transfer medium, and then the transfer layer on which the image is formed is transferred to the object to be transferred. Therefore, the image formation step, in which the image is formed, and the transfer step, in which the transfer layer on which the image is formed is transferred, can be performed separately. In the transfer step, since the image is already formed on the transfer layer, it is not necessary to locally heat the intermediate transfer medium with a thermal head. Therefore, the heating time can be extended in the transfer step, and sufficient heat can be applied to the intermediate transfer medium. Also, in the transfer step, it is not necessary to raise the temperature to a high level as in conventional local heating with a thermal head, and the heating temperature can be adjusted. For example, the heating temperature can be adjusted according to the foaming start temperature or the maximum foaming temperature of the foaming agent. Therefore, the foaming layer can be sufficiently expanded. Consequently, the force with which the transfer layer on which the image is formed is pressed against the object to be transferred becomes larger, so the transfer layer on which the image is formed is more easily pressed into the depressions of the uneven surface of the object to be transferred. This suppresses the occurrence of blurring, white spots, and blurring of the image edges.

[0029] Therefore, the intermediate transfer medium in this disclosure can achieve good transferability even to a transfer subject with low surface smoothness.

[0030] Furthermore, when manufacturing a printed object using the intermediate transfer medium in this disclosure, as shown in Figure 3(b) above, the substrate 1 and the expanded foamed layer 2 are peeled off from the transfer layer 3 transferred to the transfer surface of the object to be transferred 51. In other words, the expanded foamed layer 2 is peeled off from the transfer layer 3 transferred to the object to be transferred 51 and remains on the intermediate transfer medium. Also, as described above, since the intermediate transfer medium in this disclosure has good transferability, the transfer layer 3 on which the image 25 is formed easily follows the irregularities of the transfer surface of the object to be transferred 51. Therefore, in the printed object 50, the surface of the transfer layer 3 opposite to the object to be transferred 51 easily reflects the surface shape of the transfer surface of the object to be transferred 51. In other words, in the printed object 50, the surface of the transfer layer 3 opposite to the object to be transferred 51 comes to have a surface shape similar to the surface shape of the transfer surface of the object to be transferred 51. Therefore, in printed materials, the appearance of the surface of the transfer layer opposite the object to which the transfer layer is applied will be less different from the appearance of the transferred surface in areas where the transfer layer is not applied, thus reducing the sense of incongruity. Consequently, the texture of the image in printed materials can be improved.

[0031] Figures 17(a) to 17(c) show another example of using a heat transfer sheet 110, which has a foamed layer 102 and a colorant layer 122 in sequence on one side of a substrate 101, as in the conventional method. In the heat transfer sheet 110, the colorant layer 122 is a melt-transfer type colorant layer that is transferred itself. First, as shown in Figures 17(a) to 17(b), the colorant layer 122 of the heat transfer sheet 110 is heat-transferred onto the object to be transferred 151, and at the same time, the foamed layer 102 of the heat transfer sheet 110 is expanded. Next, as shown in Figure 17(c), the substrate 101 is peeled off from the colorant layer 122 transferred to the object to be transferred 151 and from the expanded foamed layer 102a. Thus, when the expanded foamed layer 102a is also transferred to the transfer target 151, the expanded foamed layer 102a and the colorant layer 122 fill in some of the irregularities on the transfer surface of the transfer target 151. Therefore, in the printed object 150, the shape of the surface of the expanded foamed layer 102a opposite to the transfer target 151 is different from the surface shape of the transfer surface of the transfer target 151 in the areas where the colorant layer 122 and the expanded foamed layer 102a have not been transferred. Consequently, in the printed object 150, in the areas where the colorant layer 122 and the expanded foamed layer 102a have been transferred, it may appear as if something has been attached to the transfer target 151. In particular, because delamination occurs between the substrate 101 and the foamed layer 102a, the surface of the expanded foamed layer 102a opposite to the transfer target 151 becomes smooth, resulting in an unnatural appearance due to the difference in surface shape. As a result, in the printed object 150, the areas where the colorant layer 122 and the expanded foamed layer 102a have been transferred may have a different gloss, for example, making them appear as if a sticker has been applied. Therefore, the texture of the transferred material is impaired in the printed object, resulting in a decrease in texture.

[0032] Therefore, the intermediate transfer medium in this disclosure is capable of improving print quality.

[0033] The following describes the various components of the intermediate transfer medium in this disclosure.

[0034] 1. Foamed layer The foamed layer in this disclosure contains a foaming agent. The foamed layer is a layer that, during thermal transfer, presses the transfer layer against the object to be transferred by the expansion of the foamed layer. The foamed layer is also a layer that remains on the intermediate transfer medium after an image has been formed on the surface of the transfer layer of the intermediate transfer medium and the image-formed transfer layer of the intermediate transfer medium has been transferred to the object to be transferred.

[0035] The foamed layer may be a single layer containing a foaming agent, or it may consist of multiple layers. If the foamed layer consists of multiple layers, at least one layer must contain a foaming agent. The foamed layer may also consist of a foaming agent-containing layer and a release layer, in order from the substrate side. "Single layer" means that it is composed of one layer.

[0036] (1) First embodiment of the foamed layer The foamed layer in this embodiment is a single layer containing a foaming agent.

[0037] (a) foaming agent A thermal foaming agent is preferred as the foaming agent. A thermal foaming agent is a foaming agent that expands when heated or decomposes when heated to generate gas.

[0038] Examples of foaming agents include thermally expandable microcapsules. Thermally expandable microcapsules are particles having a core-shell structure that encloses a low-temperature volatile solvent. Thermally expandable microcapsules are preferably used in this disclosure. Generally, thermally expandable microcapsules are particles in which low-boiling-point hydrocarbons are microencapsulated in a resin shell wall, and when heated at a specific temperature, their volume expands to several to several hundred times their original volume. Low-boiling-point hydrocarbons that can be encapsulated in thermally expandable microcapsules include aliphatic hydrocarbons containing fluorine atoms such as methyl chloride, methyl bromide, trichloroethane, dichloroethane, n-butane, n-heptane, n-propane, n-hexane, n-pentane, isobutane, isoheptane, neopentane, petroleum ether, Freon, or mixtures of these hydrocarbons. As materials for the shell wall of the thermally expandable microcapsules, vinylidene chloride, vinyl chloride, acrylonitrile, styrene, methyl methacrylate, ethyl methacrylate, vinyl acetate, or copolymers or blends thereof can be used. A crosslinking agent may be added to the partition material as needed.

[0039] Furthermore, pyrolysis-type chemical blowing agents may be used as blowing agents, such as organic blowing agents and inorganic blowing agents. Examples of organic blowing agents include azo blowing agents such as azodicarbonamide (ADCA), azobisformamide, and azobisisobutyronitrile; fluoride alkane blowing agents such as trichloromonofluoromethane; hydrazine blowing agents such as p-toluenesulfonyl hydrazide, hydrazolcarbonamide, and acetone-p-sulfonyl hydrazone; semicarbazide blowing agents such as p-toluenesulfonyl semicarbazide; triazole blowing agents such as 5-morpholyl-1,2,3,4-thiatriazole; N-nitroso blowing agents such as N,N-dinitrosoterephthalamide and dinitrosopentamethylenetetramine; and azide blowing agents such as p-toluenesulfonyl azide. Examples of inorganic blowing agents include ammonium carbonate, ammonium bicarbonate, ammonium nitrite, ammonium borohydride, and azides.

[0040] The average particle size of the foaming agent is preferably 0.1 to 5 times the thickness of the foamed layer. For example, the average particle size of the foaming agent may be 0.1 μm or more and 90 μm or less, or 5 μm or more and 30 μm or less. If the average particle size of the foaming agent is within the above range, the transferability of the transfer layer can be further enhanced by the expansion of the foamed layer.

[0041] The average particle size of the foaming agent is the particle size at 50% of the integrated particle size distribution (D50) determined by laser diffraction scattering. To measure the average particle size of the foaming agent, the foaming layer is dissolved in a solvent to separate the foaming agent. The solvent is not particularly limited as long as it is capable of dissolving components other than the foaming agent contained in the foaming layer, and is appropriately selected depending on the type of resin contained in the foaming layer. For example, a solvent used in the foaming layer composition used to form the foaming layer can be used. As a measuring device, for example, a Microtrac particle size analyzer manufactured by Microtrac-Bell can be used.

[0042] The foaming start temperature of the foaming agent may be, for example, 90°C to 200°C, 90°C to 160°C, 100°C to 200°C, or 120°C to 160°C. If the foaming start temperature of the foaming agent is within the above range, foaming of the foaming agent during the drying of the coating film can be suppressed when forming each layer constituting the intermediate transfer medium. In addition, expansion of the foaming layer can be suppressed when forming an image on the surface of the transfer layer of the intermediate transfer medium. This suppresses the occurrence of irregularities on the surface of the transfer layer due to the expansion of the foaming layer, and thus suppresses the occurrence of unevenness and shading in the image when forming an image on the transfer layer. Note that even if the heating temperature is relatively high in the process of forming each layer constituting the intermediate transfer medium and the process of forming an image on the transfer layer, if the heating time is very short, it is thought that the foaming agent will hardly foam at all. Furthermore, if the foaming start temperature of the foaming agent is within the above range, the deterioration of the resin contained in the foaming layer can be suppressed.

[0043] Furthermore, the maximum foaming temperature of the foaming agent may be, for example, 100°C to 200°C, or 120°C to 190°C. If the maximum foaming temperature of the foaming agent is within the above range, when transferring the transfer layer of the intermediate transfer medium to the transfer target, the foaming layer can expand sufficiently without insufficient expansion, and the transfer layer can be pressed into the recesses of the uneven surface of the transfer target.

[0044] The foaming initiation temperature and maximum foaming temperature of the foaming agent are determined by thermomechanical analysis (TMA). Specifically, when measured by thermomechanical analysis (TMA) at a heating rate of 20°C / min and a load force of 0.06 N, with temperature on the x-axis and displacement on the y-axis, the temperature at which the maximum displacement is observed is defined as the maximum foaming temperature, and the temperature at which the displacement reaches 3% relative to the maximum displacement is defined as the foaming initiation temperature. To measure the foaming initiation temperature and maximum foaming temperature of the foaming agent, the foaming layer is dissolved in a solvent to separate the foaming agent. The method for separating the foaming agent from the foaming layer is as described above.

[0045] The foaming agent content in the foamed layer is, for example, 5% by mass or more and 85% by mass or less. If the foaming agent content is within the above range, the transferability of the transfer layer can be further enhanced by the expansion of the foamed layer.

[0046] (b) Resin The foamed layer may typically contain a foaming agent and a resin. The resin is not particularly limited as long as it can disperse the foaming agent and does not hinder the expansion of the foamed layer by the foaming agent. Examples include polyester resins, acrylic resins, phenolic resins, acrylonitrile-styrene copolymers, polyimide resins, epoxy resins, cellulose resins, polyurethane resins, and polystyrene resins.

[0047] Furthermore, the softening point of the resin is preferably 100°C or lower, more preferably 90°C or lower, even more preferably 85°C or lower, and particularly preferably 80°C or lower. If the softening point of the resin is within the above range, it is possible to avoid hindering the expansion of the foamed layer by the foaming agent. On the other hand, the softening point of the resin may also be, for example, 40°C or higher.

[0048] The softening point of the resin is measured using a nanoscale thermal analysis (nanoTA) system. A scanning thermal microscope (Anasys NanoTA) is used, with the probe tip in contact with the cross-sectional surface of the foamed layer. The probe is heated at a heating rate of 5°C / min, and the displacement of the probe is measured. The cantilever model of the thermal probe is, for example, EX-AN2-200. The temperature at which the probe displacement is maximum is defined as the softening point of the resin. Five measurements are taken by changing the measurement position, and the average of the five measurements is used.

[0049] (c) Additives The foamed layer may contain a release agent. For example, the foamed layer may contain a release agent, and if the transfer layer has a release layer on the side facing the foamed layer, as described later, the release layer may contain a release agent, or both the foamed layer and the release layer may contain a release agent. In addition, the foamed layer may contain additives as needed.

[0050] (c) Characteristics of the foamed layer The foamed layer can be expanded, for example, by an expansion ratio of 2 to 25 times. The above expansion ratio may also be, for example, 2 to 15 times, or 2 to 12 times. If the expansion ratio is within the above range, the transferability of the transfer layer can be further improved by the expansion of the foamed layer. The expansion ratio is the value obtained when the foamed layer of the intermediate transfer medium is expanded by heating at 1 atmosphere (1013 hectopascals), and is calculated by the following formula. Expansion ratio (times) = Thickness of foamed layer after expansion / Thickness of foamed layer before expansion

[0051] The thickness of the foamed layer is preferably 0.2 to 10 times the average particle size of the foaming agent. Alternatively, the thickness of the foamed layer may be greater than or equal to the average particle size of the foaming agent. For example, the thickness of the foamed layer may be 5 μm to 90 μm, 5 μm to 30 μm, or 5 μm to 15 μm. If the thickness of the foamed layer is within the above range, the expansion of the foamed layer can further enhance the transferability of the transfer layer.

[0052] In this specification, the thickness of each layer is the average value of 10 arbitrary thicknesses obtained by measuring the cross-section in the thickness direction of the intermediate transfer medium as observed by a scanning electron microscope (SEM).

[0053] (2) Second embodiment of the foamed layer The foamed layer 2 of this embodiment, as shown in Figure 4, for example, has a foaming agent-containing layer 2a and a release layer 2b, in that order from the substrate 1 side. In this case, the degree of freedom in selecting the resin used for the foaming agent-containing layer is increased. Furthermore, the release properties at the interface between the foamed layer and the transfer layer can be improved.

[0054] In this embodiment, the foamed layer 2 may have an intermediate adhesive layer 2c between the foaming agent-containing layer 2a and the release layer 2b, as illustrated in Figure 4. This improves the adhesion between the foaming agent-containing layer and the release layer, thereby improving the peelability at the interface between the foamed layer and the transfer layer.

[0055] (a) Foaming agent-containing layer The foaming agent and resin contained in the foaming agent-containing layer are the same as those described in the first embodiment of the foamed layer. Other aspects of the foaming agent-containing layer are also the same as those described in the first embodiment of the foamed layer.

[0056] (b) Release layer For the release layer, known release layers used in thermal transfer sheets or intermediate transfer media for fusion-type or sublimation-type thermal transfer methods can be used.

[0057] (c) Intermediate adhesive layer The material of the intermediate adhesive layer is not particularly limited as long as it can improve the adhesion between the foaming agent-containing layer and the release layer, and conventionally known materials can be used. The thickness of the intermediate adhesive layer is not particularly limited, for example, 0.1 μm or more and 5 μm or less.

[0058] 2. Transfer layer The transfer layer constituting the intermediate transfer medium in this disclosure is a transfer layer before image formation. After an image is formed on the transfer layer, it is peeled off from the foamed layer after expansion during thermal transfer and transferred to the object to be transferred.

[0059] The transfer layer has a printable surface on the side opposite to the foamed layer. On-demand printing is one printing method. On-demand printing refers to a printing method that allows printing from digital data without using printing plates. Examples of on-demand printing methods include thermal transfer, inkjet, and electrophotography. Examples of electrophotography methods include laser and LED (light-emitting diode) methods.

[0060] In the transfer layer, the printable surface is appropriately selected depending on the printing method. The transfer layer may have a surface to which ink can be fixed, or it may have a receiving layer to which ink can be received. In the case of a dye-sublimation thermal transfer method, the transfer layer has a receiving layer as a printable surface. On the other hand, in the case of a melt-type thermal transfer method, the transfer layer has a surface to which the melt-transfer type colorant layer of the thermal transfer sheet can be transferred as a printable surface. In this case, the transfer layer may have a receiving layer as a printable surface. In the case of an inkjet method, the transfer layer has a surface to which ink can be fixed as a printable surface. In this case, the transfer layer may have a receiving layer as a printable surface. In the case of an electrophotographic method, the transfer layer has a surface to which toner can be fixed as a printable surface. Among these, the thermal transfer method is preferred. Highly aesthetic images can be obtained. In the dye-sublimation thermal transfer method, it is possible to produce prints with high gradation and a wide color reproduction gamut. The fused thermal transfer method allows for the transfer of highly lightfast colorants and enables printing with metallic or pearlescent finishes.

[0061] Furthermore, as illustrated in Figure 5(a), the transfer layer 3 may have a release layer 12 on the side facing the foamed layer 2. This improves the peelability of the transfer layer from the expanded foamed layer during thermal transfer.

[0062] Furthermore, as illustrated in Figure 5(b), the transfer layer 3 may have a protective layer 13 on the side facing the foamed layer 2. By placing the protective layer on the outermost surface of the transfer layer on the foamed layer side, the image formed on the transfer layer after transfer can be protected, improving the durability of the image. The release layer may also serve as the protective layer.

[0063] In the case of a sublimation thermal transfer method, as illustrated in Figures 5(a) and 5(b), the transfer layer 3 has a receiving layer 11 on the side opposite to the foamed layer 2. In this case, the transfer layer 3 may have a release layer 12 and a receiving layer 11 in that order from the foamed layer 2 side, or it may have a protective layer 13 and a receiving layer 11. Also, as mentioned above, the release layer may also serve as the protective layer.

[0064] The following describes each layer that makes up the transfer layer.

[0065] (1) Receptor layer The transfer layer may have an ink-receiving layer as needed.

[0066] In the sublimation thermal transfer method, an image is formed on a receiving layer from a thermal transfer sheet having a sublimation-transferable colorant layer by thermal transfer. Then, the transfer layer on which the image of the intermediate transfer medium has been formed is transferred to the object to be transferred, and a printed object is obtained. As the material for the receiving layer, conventionally known resin materials that readily accept heat-transferable colorants such as sublimation dyes can be used. Examples include polyolefin resins such as polypropylene, halogenated resins such as polyvinyl chloride or polyvinylidene chloride, vinyl resins such as polyvinyl acetate, vinyl chloride-vinyl acetate copolymers, ethylene-vinyl acetate copolymers or polyacrylic acid esters, polyester resins such as polyethylene terephthalate or polybutylene terephthalate, polystyrene resins, polyamide resins, copolymer resins of olefins such as ethylene or propylene and other vinyl polymers, cellulose resins such as ionomers or cellulose diastase, and polycarbonate. Among these, vinyl chloride resins, acrylic-styrene resins, or polyester resins are preferred. The resin material may be used alone or in combination of two or more types.

[0067] In inkjet systems, a swollen or porous ink-receiving layer can be used as the ink-receiving layer, as needed.

[0068] When a transfer layer containing a receptive layer on which an image has been formed is transferred to a substrate via a heat-seal layer, the adhesiveness of the receptive layer itself is not necessarily required. On the other hand, when a transfer layer containing a receptive layer on which an image has been formed is transferred to a substrate without a heat-seal layer, it is preferable that the receptive layer contains an adhesive resin material such as a vinyl chloride-vinyl acetate copolymer.

[0069] The receiving layer may contain various additives as needed.

[0070] The receiving layer can be formed by preparing a receiving layer composition by dissolving or dispersing the above-mentioned resin material and, if necessary, additives in a suitable solvent such as water or an organic solvent, and then applying and drying the receiving layer composition. Conventional coating methods include gravure printing, screen printing, or reverse coating using a gravure plate. The thickness of the receiving layer is, for example, 1 μm to 10 μm.

[0071] (2) Detachment layer The transfer layer may have a release layer on the side facing the foamed layer. The release layer is any layer that constitutes the transfer layer and is transferred to the transfer target during heat transfer. The release layer can improve the peelability of the transfer layer from the foamed layer after expansion during heat transfer. Furthermore, if the release layer also serves as the protective layer described later, the durability of the print formed using the intermediate transfer medium can be improved. Moreover, if the transfer layer has a release layer and a protective layer in that order from the foamed layer side, the durability of the print can be further improved.

[0072] Conventionally known materials can be used as the material for the release layer. Examples include cellulose derivatives such as ethylcellulose, nitrocellulose, and cellulose acetate; acrylic resins such as polymethyl methacrylate, polyethyl methacrylate, and polybutyl acrylate; and thermoplastic resins such as polyvinyl chloride, vinyl chloride-vinyl acetate copolymers, and polyvinyl butyral. Other examples include thermosetting resins such as saturated or unsaturated polyester resins, polyurethane resins, thermocrosslinkable epoxy-amino resins, and aminoalkyd resins. Silicone waxes, silicone resins, silicone-modified resins, fluororesins, fluoro-modified resins, and polyvinyl alcohols can also be used. These materials may be used individually or in combination of two or more.

[0073] The release layer may contain fillers. This can improve foil tearability.

[0074] The release layer can be formed by dispersing or dissolving the above-mentioned materials in a solvent to prepare a release layer composition, and then applying and drying the release layer composition. Conventional coating methods include roll coating, gravure coating, and bar coating. The thickness of the release layer is, for example, 0.1 μm to 5 μm, and may be 0.5 μm to 2 μm.

[0075] (3) Protective layer The transfer layer may have a protective layer on the side facing the foamed layer. The protective layer is any layer that constitutes the transfer layer and is transferred to the transfer target during heat transfer. The protective layer can improve the durability of the print formed using the intermediate transfer medium, specifically its abrasion resistance and plasticizer resistance.

[0076] The material of the protective layer is not particularly limited, and conventionally known materials can be used. Examples include polyester, polycarbonate, acrylic resin, polyvinyl chloride resin, UV-absorbing resin, epoxy resin, polystyrene, polyurethane, acrylic urethane resin, silicone-modified resins of these resins, mixtures of these resins, ionizing radiation-curable resins, and UV-absorbing resins.

[0077] The protective layer may contain fillers. This can improve foil tearability.

[0078] The protective layer can be formed by preparing a protective layer composition by dissolving or dispersing the above-mentioned materials in a suitable solvent, and then applying and drying the protective layer composition. Conventional application methods include gravure printing, screen printing, or reverse coating using a gravure plate. The thickness of the protective layer is, for example, 2 μm to 30 μm.

[0079] 3. Base material The substrate is a member that supports the transfer layer and the foamed layer described above. The substrate is not particularly limited, and a resin film can be used. Examples of resins that make up the resin film include polyester, polypropylene, polycarbonate, cellulose acetate, polyethylene derivatives, polyamide, and polymethylpentene. Examples of polyesters include polyethylene terephthalate and polyethylene naphthalate. The resin film may be a stretched film or an unstretched film. The resin film may be a single-layer film or a composite film formed by laminating two or more films containing the above resins. Furthermore, the substrate may be a resin film containing voids inside.

[0080] The thickness of the base material is preferably somewhat thick, from the viewpoint of ease of peeling the intermediate transfer medium from the intermediate transfer medium with the release agent described later, ease of handling from the intermediate transfer medium after peeling it from the intermediate transfer medium with the release agent until it is placed in the heat transfer device (press machine), heat resistance at the heat source, curl suppression, and prevention of breakage and wrinkles during work. The thickness of the base material is appropriately selected according to the type of resin described above so that the desired strength and heat resistance can be obtained. For example, the thickness of the base material may be 1 μm or more, 3 μm or more, preferably 20 μm or more, and more preferably 30 μm or more. On the other hand, the thickness of the base material may be, for example, 500 μm or less, 400 μm or less, 200 μm or less, or 100 μm or less. Specifically, the thickness of the substrate may be 1 μm or more and 500 μm or less, 3 μm or more and 500 μm or less, 3 μm or more and 400 μm or less, 20 μm or more and 200 μm or less, 30 μm or more and 100 μm or less, or 1 μm or more and 100 μm or less.

[0081] 4.First adhesive layer The intermediate transfer medium 10 in this disclosure may have a first adhesive layer 4 between the substrate 1 and the foamed layer 2, as illustrated in Figure 4. The first adhesive layer can improve the adhesion between the substrate and the foamed layer. This improves the peelability of the transfer layer from the expanded foamed layer during thermal transfer.

[0082] The material of the first adhesive layer is not particularly limited as long as it can improve the adhesion between the substrate and the foamed layer, and conventionally known materials can be used. The thickness of the first adhesive layer is not particularly limited, for example, 0.1 μm or more and 5 μm or less.

[0083] B. Intermediate transfer medium with release agent The intermediate transfer medium with a release member in this disclosure comprises the intermediate transfer medium described above and a release member disposed on the substrate-side surface of the intermediate transfer medium.

[0084] Figure 6(a) is a schematic cross-sectional view illustrating an intermediate transfer medium with a release agent in this disclosure. As shown in Figure 6(a), the intermediate transfer medium 30 with a release agent comprises an intermediate transfer medium 10 and a release agent 31 disposed on the substrate 1 side of the intermediate transfer medium 10.

[0085] The intermediate transfer medium with a release agent in this disclosure has the same effects as the intermediate transfer medium described above, and therefore provides the same advantages and disadvantages as the intermediate transfer medium described above.

[0086] 1. Intermediate transfer medium The intermediate transfer medium is the same as described in "A. Intermediate Transfer Medium" above.

[0087] 2. Release agent In this disclosure, the release member is positioned on the substrate-side surface of the intermediate transfer medium. The release member is positioned on the intermediate transfer medium during image formation on the transfer layer, and is peeled off from the intermediate transfer medium before the transfer layer is transferred to the object to be transferred. By positioning the release member on the substrate-side surface of the intermediate transfer medium, the suitability of the printer for image formation on the transfer layer can be improved.

[0088] As shown in Figure 6(a), the release member 31 may be a single layer. Alternatively, as shown in Figure 6(b), the release member 31 may have multiple layers, for example, a resin layer 33 and a support 32 in that order from the substrate 1 side. The dynamic friction coefficients on both sides of the release member 5 may be 0.3 or more and 0.9 or less. This is to improve the suitability of the printer for transporting the material when forming an image on the transfer layer. An example of such a release member is the release member described in Japanese Patent No. 7120472.

[0089] The support is a single layer or multiple layers. The support may be in contact with the intermediate transfer medium. In this case, it is preferable that the support is such that the coefficient of dynamic friction on both sides of the release member is 0.3 or more and 0.9 or less. Also, as shown in Figure 6(b), the support 32 may be in contact with the resin layer 32. The resin layer can improve the adhesion between the intermediate transfer medium and the release member. In this case, the side of the resin layer facing the intermediate transfer medium becomes the surface of the release member, and the side of the support opposite to the resin layer becomes the back surface of the release member.

[0090] The support may be a resin substrate or a paper substrate. Examples of resin substrates include polyester such as polyethylene terephthalate, polyarylate, polycarbonate, polyurethane, polyimide, polyetherimide, cellulose derivatives, polyethylene, ethylene-vinyl acetate copolymer, polypropylene, polystyrene, acrylic, polyvinyl chloride, polyvinylidene chloride, polyvinyl alcohol, polyvinyl butyral, nylon, polyetheretherketone, polysulfone, polyethersulfone, tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer, polyvinyl fluoride, tetrafluoroethylene-ethylene copolymer, tetrafluoroethylene-hexafluoropropylene copolymer, polychlorotrifluoroethylene, and polyvinylidene fluoride. Examples of paper substrates include condenser paper, glassine paper, sulfuric acid paper, synthetic paper, fine paper, art paper, coated paper, uncoated paper, cast coated paper, wallpaper, cellulose fiber paper, synthetic resin-impregnated paper, backing paper, and impregnated paper (synthetic resin-impregnated paper, emulsion-impregnated paper, synthetic rubber latex-impregnated paper). The support may include multiple resin substrates. The support may also include multiple paper substrates. Furthermore, the support may include one or more resin substrates and one or more paper substrates.

[0091] The support may be bonded to the side facing the resin layer. Examples of bonding treatments include corona discharge treatment, flame treatment, ozone treatment, ultraviolet treatment, radiation treatment, surface roughening treatment, chemical treatment, plasma treatment, low-temperature plasma treatment, and grafting treatment. The support may also be bonded to the side opposite to the resin layer. In this specification, primer treatment includes a configuration in which a primer layer is provided on the side of the support facing the resin layer.

[0092] The release agent may include a void layer. By including a void layer in the release agent, a high-density image can be formed on the printable surface of the transfer layer. Examples of void layers include films having voids inside. Voids are sometimes referred to as microvoids or pores. Films having voids inside may also be resin substrates. Examples of void layers include those produced by kneading inorganic particles into a polymer and creating voids with the inorganic particles as nuclei when the mixture is stretched, and those produced by mixing one or more types of immiscible polymers with a main resin and creating voids when the mixture is stretched.

[0093] The release agent may have a laminated structure in which a support, a void layer, and a resin layer are stacked in that order. Alternatively, the release agent may have a laminated structure in which a void layer, a support, a void layer, and a resin layer are stacked in that order.

[0094] The thickness of the intermediate transfer medium with release agent is, for example, 50 μm to 1500 μm, preferably 100 μm to 300 μm, and more preferably 150 μm to 250 μm. By having the thickness of the intermediate transfer medium with release agent within the above range, the suitability of the printer for image formation on the transfer layer can be improved.

[0095] The thickness of the release agent is not particularly limited, but it is preferable to set it so that the thickness of the intermediate transfer medium with the release agent is the thickness described above, taking into consideration the thickness of the intermediate transfer medium, etc. The same applies to the thickness of the resin layer and the thickness of the support.

[0096] C. Combination of intermediate transfer medium and heat transfer sheet The combination of this embodiment is a combination of the above-mentioned intermediate transfer medium and a heat transfer sheet, wherein the heat transfer sheet has a colorant layer.

[0097] The aforementioned intermediate transfer medium is a transfer sheet before an image is formed on the transfer layer, and is an image-forming sheet. Therefore, the aforementioned intermediate transfer medium can be used in combination with a thermal transfer sheet having a colorant layer for forming an image.

[0098] 1. Intermediate transfer medium The intermediate transfer medium is the same as described in "A. Intermediate Transfer Medium" above. Alternatively, the intermediate transfer medium with a release agent as described above may be used as the intermediate transfer medium.

[0099] 2. Heat transfer sheet As shown in Figure 7(a), the heat transfer sheet has a heat transfer sheet 20A having a colorant layer 22.

[0100] Furthermore, the thermal transfer sheet may be a thermal transfer sheet 20C having a support 21c, a colorant layer 22 (yellow colorant layer 22Y, magenta colorant layer 22M, cyan colorant layer 22C) and a heat seal layer 23 arranged on the same surface of the support 21c, as shown in Figure 7(c). It may also have a thermal transfer sheet 20A having a colorant layer 22 as shown in Figure 7(a) and a thermal transfer sheet 20B having a heat seal layer 23 as shown in Figure 7(b).

[0101] Furthermore, the thermal transfer sheet may be a thermal transfer sheet 20D having a support 21d, a colorant layer 22 (yellow colorant layer 22Y, magenta colorant layer 22M, cyan colorant layer 22C), an opacity layer 24, and a heat seal layer 23 arranged on the same surface of the support 21d, as shown in Figure 7(d); or it may have a thermal transfer sheet 20C having a support 21c, a colorant layer 22 and a heat seal layer 23 arranged on the same surface of the support 21c, as shown in Figure 7(c); or it may have a thermal transfer sheet 20A having a colorant layer 22 as shown in Figure 7(a), a thermal transfer sheet 20B having a heat seal layer 23 as shown in Figure 7(b), and a thermal transfer sheet 20E having an opacity layer 24 as shown in Figure 7(e).

[0102] (1) Color material layer The colorant layer is a layer for forming an image on the surface of the transfer layer of the intermediate transfer medium.

[0103] The colorant layer may be a sublimation transfer type colorant layer in which the colorant contained in the colorant layer is transferred, or a melt transfer type colorant layer in which the colorant layer itself is transferred. The heat transfer sheet may have both a sublimation transfer type colorant layer and a melt transfer type colorant layer.

[0104] The sublimation transfer type colorant layer contains a colorant and a binder resin. A sublimation dye is used as the colorant. The colorant and binder resin contained in the sublimation transfer type colorant layer can be known materials used for the sublimation transfer type colorant layer of a heat transfer sheet.

[0105] The molten transfer type colorant layer contains a colorant and a binder resin. The colorant may be a pigment or a dye. The colorant and binder resin contained in the molten transfer type colorant layer can be known materials used for the molten transfer type colorant layer of a heat transfer sheet.

[0106] A thermal transfer sheet may have one colorant layer on one side of the support, or it may have multiple colorant layers of different hues arranged sequentially on each side. Examples of multiple colorant layers include a yellow colorant layer, a magenta colorant layer, and a cyan colorant layer.

[0107] (2) Support The support is not particularly limited, and for example, a resin film can be used. The resin film can be a known resin film used for thermal transfer sheets.

[0108] (3) Heat seal layer The heat seal layer is a layer that melts or softens upon heating and is transferred from the heat transfer sheet to the surface of the transfer layer of the intermediate transfer medium. The heat seal layer is a layer for bonding the transfer layer on which the image of the intermediate transfer medium is formed to the object to be transferred. The material of the heat seal layer can be any known material used for the heat seal layer of a heat transfer sheet.

[0109] (4) Release layer A release layer may be placed between the support and the heat seal layer. The release layer can improve the peelability of the heat seal layer. The release layer is the layer that remains on the heat transfer sheet when the heat seal layer of the heat transfer sheet is transferred to the surface of the transfer layer of the intermediate transfer medium. The material of the release layer can be any known material used for the release layer of a heat transfer sheet.

[0110] (5) Peel-off layer The thermal transfer sheet may have a peel-off layer. The peel-off layer is a layer for removing a portion of the transfer layer on which the image of the intermediate transfer medium has been formed. The material of the peel-off layer can be any known material used for the peel-off layer of a thermal transfer sheet.

[0111] (6) Block layer The thermal transfer sheet may have a block layer. The block layer is a layer that is transferred from the thermal transfer sheet to the surface of the transfer layer of the intermediate transfer medium, and functions as a masking member when transferring the transfer layer of the intermediate transfer medium to the surface of the object to be transferred, preventing a portion of the transfer layer of the intermediate transfer medium from being transferred to the object to be transferred. The material of the block layer can be any known material used for the block layer of a thermal transfer sheet. An example of a block layer is the block layer described in Japanese Patent International Publication No. 2019 / 151378.

[0112] (7) Back layer The thermal transfer sheet may have a backing layer on the side opposite to the colorant layer of the support. The backing layer can suppress fusion with the thermal head and other components during thermal transfer, and can also improve slipperiness. The material of the backing layer can be any known material used for the backing layer of a thermal transfer sheet.

[0113] (8) Concealing layer The heat transfer sheet may have an opacity layer. The opacity layer is a layer that is transferred from the heat transfer sheet to the surface of the transfer layer of the intermediate transfer medium. The opacity layer is also a layer that is placed between the object to be transferred and the image when the transfer layer on which the image of the intermediate transfer medium is formed is transferred to the object to be transferred, and is used to conceal the color of the object to be transferred. The material of the opacity layer can be a known material used for the opacity layer of a heat transfer sheet. Alternatively, the heat seal layer may contain the material of the opacity layer and thus also serve as the opacity layer.

[0114] D. Combinations of intermediate transfer medium, heat transfer sheet, and transfer target. The combination of this embodiment is a combination of the above-mentioned intermediate transfer medium, a heat transfer sheet, and a transfer object, wherein the heat transfer sheet is a heat transfer sheet having a colorant layer.

[0115] The aforementioned intermediate transfer medium is a transfer sheet used before an image is formed on the transfer layer, and is an image-forming sheet. Therefore, the aforementioned intermediate transfer medium can be used in combination with a thermal transfer sheet having a colorant layer for forming an image, and a transfer target.

[0116] 1. Intermediate transfer medium The intermediate transfer medium is the same as described in "A. Intermediate Transfer Medium" above. Alternatively, the intermediate transfer medium with a release agent as described above may be used as the intermediate transfer medium.

[0117] 2. Heat transfer sheet The thermal transfer sheets are the same as those described in "C. Combinations of Intermediate Transfer Medium and Thermal Transfer Sheet" above.

[0118] 3. Transferee A transfer layer on which the image of the aforementioned intermediate transfer medium is formed is transferred to the transfer surface of the transfer target, and a printed object is obtained. The transfer target is not particularly limited, but it is preferable that the transfer target has an uneven surface.

[0119] Examples of materials to be transferred include paper, cloth, and wood. Among these, cloth is preferred. Generally, cloth has a rougher surface than paper. In this disclosure, as described above, good transferability can be obtained even when the surface roughness of the material to be transferred is high. Therefore, this disclosure is useful when the material to be transferred is cloth. Examples of cloth include woven fabrics, nonwoven fabrics, knitted fabrics, lace, felt, and tuft. When using cloth, the material to be transferred may be a fabric (material) or a cloth product. A cloth product may be made from the above-mentioned cloths, but woven products and nonwoven products are preferred. In this specification, fabric (material) and cloth products are collectively referred to as textiles.

[0120] The arithmetic mean height Sa of the transfer surface of the material to be transferred is preferably, for example, 1.0 μm or more and 200 μm or less, more preferably 1.2 μm or more and 150 μm or less, and even more preferably 1.5 μm or more and 100 μm or less. When the material to be transferred is cloth, and especially when the material to be transferred is textile, the arithmetic mean height Sa of the transfer surface of the material to be transferred is preferably, for example, 8 μm or more and 200 μm or less, more preferably 10 μm or more and 150 μm or less, and even more preferably 15 μm or more and 100 μm or less. In this disclosure, as described above, good transferability can be obtained even when the surface roughness of the material to be transferred is large. Therefore, this disclosure is useful when the Sa of the transfer surface of the material to be transferred is relatively large as described above.

[0121] The maximum height Sz of the transfer surface of the transfer object is preferably, for example, 200 μm or more and 900 μm or less, and more preferably 250 μm or more and 800 μm or less. When a printed object is manufactured using the intermediate transfer medium of this disclosure, the foaming agent in the foamy layer foams and the foamy layer expands, so when the transfer layer of the intermediate transfer medium is pressed against the transfer object, if the Sz of the transfer surface of the transfer object is within the above range, the adhesion between the recesses of the unevenness of the transfer surface of the transfer object and the transfer layer will be improved.

[0122] The arithmetic mean curvature Spc of the peaks of the transfer surface of the object to be transferred is preferably, for example, 2000 [1 / mm] or more and 12000 [1 / mm] or less, and more preferably 4000 [1 / mm] or more and 9000 [1 / mm] or less. Spc represents the average of the principal curvatures of the peaks of the surface. A small Spc indicates that the points in contact with other objects are rounded. A large Spc indicates that the points in contact with other objects are sharp. If the Spc of the transfer surface of the object to be transferred is within the above range, the surface of the object to be transferred will feel smooth. Furthermore, when manufacturing a printed object using the intermediate transfer medium in this disclosure, the foaming agent in the foamed layer foams and the foamed layer expands, and when the transfer layer of the intermediate transfer medium is pressed against the object to be transferred, if the Spc of the transfer surface of the object to be transferred is within the above range, it is possible to suppress the occurrence of cracks and fissures in the transfer layer transferred to the object to be transferred.

[0123] The Sdr ratio of the unfolded area at the interface of the transfer surface of the transfer target is preferably 5 to 100, and more preferably 12 to 65. Sdr represents how much the unfolded area (surface area) of a defined region increases relative to the area of ​​the defined region. The Sdr of a perfectly flat surface is 0. Also, if the surface is sloped, the Sdr will be larger. When a printed object is manufactured using the intermediate transfer medium in this disclosure, the foaming agent in the foamed layer foams and the foamed layer expands, and when the transfer layer of the intermediate transfer medium is pressed against the transfer target, if the Sdr at the interface of the transfer surface of the transfer target is within the above range, the adhesion between the recesses of the unevenness of the transfer surface of the transfer target and the transfer layer will be improved, and image deformation can be suppressed.

[0124] The arithmetic mean height Sa, maximum height Sz, arithmetic mean curvature Spc of the peaks, and interface area ratio Sdr of the transferred surface of the transferred object are measured using a laser microscope in accordance with ISO 25178:2012. Details of the measurement conditions are described in the examples.

[0125] E. Printed materials The prints described herein have three embodiments. Each embodiment will be described below.

[0126] E-1. First Embodiment of a Printed Material The print of this embodiment is a print comprising a transfer surface and a transfer layer having an image, wherein the transfer surface is cloth, and the arithmetic mean height Sa of the transfer layer on the side opposite to the transfer surface is 1.0 μm or more and 200 μm or less.

[0127] Figure 8 is a schematic cross-sectional view illustrating the print of this embodiment. As shown in Figure 8, the print 50 comprises a transfer surface 51 and a transfer layer 3 having an image 25, which is placed on the transfer surface of the transfer surface 51. The transfer surface 51 is cloth. The Sa of the side of the transfer layer 3 opposite to the transfer surface 51 is within a predetermined range.

[0128] The prints of this embodiment can be manufactured using the intermediate transfer medium described above. Therefore, they exhibit the same effects and advantages as the intermediate transfer medium described above.

[0129] Furthermore, as shown in Figures 16(a) to 16(c), when manufacturing a printed object using a conventional thermal transfer sheet 110 having a foamed layer 102 and a colorant layer 122 sequentially on one side of a base material 101, the colorant layer 122 is transferred only to the convex parts of the uneven surface of the transfer target 151 in the printed object 150, as shown in Figure 16(b). In such a case, the colorant layer 122 becomes scattered. Therefore, it is difficult to measure the Sa on the side of the transfer layer opposite to the transfer target.

[0130] 1. Transfer layer In this embodiment, the arithmetic mean height Sa of the transfer layer on the side opposite to the object to be transferred is 1.0 μm or more and 200 μm or less.

[0131] Furthermore, if Sa1 is the arithmetic mean height of the surface of the material to be transferred in the area where the transfer layer is not placed, and Sa2 is the arithmetic mean height of the side of the transfer layer opposite the material to be transferred, the ratio of Sa2 / Sa1 is not particularly limited, but is preferably Sa2 / Sa1≧0.05, more preferably Sa2 / Sa1≧0.10, even more preferably Sa2 / Sa1≧0.20, and even more preferably Sa2 / Sa1≧0.25. If the ratio of Sa2 / Sa1 is within the above range, the transfer layer is transferred without impairing the texture of the material to be transferred, so a print with a high design quality can be obtained.

[0132] The arithmetic mean height Sa1 of the surface of the material to be transferred in the region where the transfer layer is not placed, and the arithmetic mean height Sa2 of the surface of the transfer layer opposite the material to be transferred, are measured using a laser microscope in accordance with ISO 25178:2012. Details of the measurement conditions are described in the examples.

[0133] It is preferable that the transfer layer has an uneven surface on the side opposite to the object to be transferred that differs from the shape of the object to be transferred and the shape of the layers constituting the transfer layer other than the layer located on the side of the transfer layer opposite to the object to be transferred. The print in this embodiment is manufactured using the intermediate transfer medium described above. Therefore, as shown in Figure 9(a), when heat and pressure are applied to expand the foamy layer 2, and the transfer layer 3 on which the image 25 of the intermediate transfer medium 10 is formed is transferred to the transfer surface of the object to be transferred 51, an uneven surface originating from the expanded foamy layer 2 is formed on the expanded foamy layer 2 side of the transfer layer 3. In this case, as shown in Figure 9(b), in the print 50, the transfer layer 3 has an uneven surface on the side opposite to the object to be transferred 51 that differs from the shape of the object to be transferred 51 and the shape of the layers constituting the transfer layer 3 other than the layer located on the side of the transfer layer 3 opposite to the object to be transferred. In the method for manufacturing a printed object, during image formation, the image 25 may be formed on the surface of the transfer layer 3, or it may be formed by the transfer of colorant into the transfer layer 3; however, during transfer, the colorant is not transferred to the object to be transferred 51.

[0134] The surface of the transfer layer opposite to the material being transferred is observed using a laser microscope. The measurement conditions are the same as those for Sa described above.

[0135] The transfer layer has an image. Preferably, the image is formed by an on-demand printing method. The printing method is the same as described in "A. Intermediate Transfer Medium 2. Transfer Layer" above. The image is a thermal transfer image in the case of a thermal transfer method, a toner image in the case of an electrophotographic method, and an ink image in the case of an inkjet method.

[0136] Furthermore, the transfer layer may have a release layer on the side opposite to the object to be transferred. When manufacturing a printed object using the above-described intermediate transfer medium, the peelability of the transfer layer from the expanded foamed layer during thermal transfer can be improved.

[0137] Furthermore, the transfer layer may have a protective layer on the side opposite to the object being transferred. The protective layer can protect the image on the transfer layer and improve the image's durability. The release layer may also serve as the protective layer.

[0138] The transfer layer is the same as described in "A. Intermediate Transfer Medium 2. Transfer Layer" above, except that the transfer layer contains an image.

[0139] 2. Transferee In this embodiment, the material to be transferred is cloth. The cloth is the same as described in "D. Combination of Intermediate Transfer Medium, Heat Transfer Sheet, and Material to be Transferred" above. The material to be transferred is preferably a textile.

[0140] 3. Other layers The printed material of this embodiment may have a heat seal layer between the object to be transferred and the transfer layer having the image. Furthermore, the printed material of this embodiment may have an opacity layer between the object to be transferred and the transfer layer having the image. Also, the printed material of this embodiment may have a heat seal layer and an opacity layer between the object to be transferred and the transfer layer having the image, in that order from the object to be transferred side. The heat seal layer and opacity layer are the same as those described in "C. Combination of Intermediate Transfer Medium and Heat Transfer Sheet" above.

[0141] 4. Manufacturing method of printed materials The prints of this embodiment are preferably manufactured by the print manufacturing method described later.

[0142] E-2. Second Embodiment of the Printed Material The print of this embodiment is a print comprising a transfer surface and a transfer layer having an image, wherein the arithmetic mean height Sa of the transfer surface of the transfer surface is 1.0 μm or more and 200 μm or less, and the arithmetic mean height Sa of the transfer layer on the side opposite to the transfer surface is 1.0 μm or more and 200 μm or less.

[0143] Figure 8 is a schematic cross-sectional view illustrating an example of a print according to this embodiment. As shown in Figure 8, the print 50 comprises a transfer body 51 and a transfer layer 3 having an image 25, which is disposed on the transfer surface of the transfer body 51. The Sa of the transfer surface of the transfer body 51 is within a predetermined range, and the Sa of the transfer layer 3 on the side opposite to the transfer body 51 is within a predetermined range.

[0144] The prints of this embodiment can be manufactured using the intermediate transfer medium described above. Therefore, they exhibit the same effects and advantages as the intermediate transfer medium described above.

[0145] 1. Transfer layer The transfer layer in this embodiment is the same as the transfer layer in the first embodiment of the printed material described above.

[0146] 2. Transferee In this embodiment, the arithmetic mean height Sa of the transfer surface of the transfer object is 1.0 μm or more and 200 μm or less.

The heat seal layer and opacity layer are the same as those described in "C. Combination of Intermediate Transfer Medium and Heat Transfer Sheet" above.

[0149] 4. Manufacturing method of printed materials The prints of this embodiment are preferably manufactured by the print manufacturing method described later.

[0150] E-3. Third Embodiment of the Printed Material The print of this embodiment is a print comprising a transfer surface and a transfer layer having an image, wherein Sa1 is the arithmetic mean height of the surface of the transfer surface in the region where the transfer layer is not placed, and Sa2 is the arithmetic mean height of the side of the transfer layer opposite to the transfer surface, and Sa2 / Sa1 ≥ 0.05.

[0151] Figure 8 is a schematic cross-sectional view illustrating an example of a print according to this embodiment. As shown in Figure 8, the print 50 comprises a transfer body 51 and a transfer layer 3 having an image 25, which is disposed on the transfer surface of the transfer body 51. Although not shown, the arithmetic mean height Sa1 of the surface of the transfer body 51 in areas where the transfer layer 3 is not disposed and the arithmetic mean height Sa2 of the transfer surface of the transfer body 51 have a predetermined relationship.

[0152] The prints of this embodiment can be manufactured using the intermediate transfer medium described above. Therefore, they exhibit the same effects and advantages as the intermediate transfer medium described above.

[0153] 1. Transfer layer In this embodiment, if Sa1 is the arithmetic mean height of the surface of the object to be transferred in the region where the transfer layer is not placed, and Sa2 is the arithmetic mean height of the side of the transfer layer opposite to the object to be transferred, then Sa2 / Sa1 ≥ 0.05.

The heat seal layer and opacity layer are the same as those described in "C. Combination of Intermediate Transfer Medium and Heat Transfer Sheet" above.

[0156] 4. Manufacturing method of printed materials The prints of this embodiment are preferably manufactured by the print manufacturing method described later.

[0157] F. Method of manufacturing a photographic print The present disclosure is a method for manufacturing a printed object, comprising: a preparation step of preparing an intermediate transfer medium having a substrate, a foaming layer containing a foaming agent, and a transfer layer in that order; an image forming step of forming an image on the surface of the transfer layer of the intermediate transfer medium; a transfer step of placing the surface of the transfer layer on which the image is formed on the intermediate transfer medium facing the surface of the transfer object to be transferred, and applying heat and pressure to expand the foaming layer while transferring the transfer layer on which the image is formed on the intermediate transfer medium to the surface of the transfer object; and a peeling step of peeling the substrate and the expanded foaming layer from the transfer layer transferred to the surface of the transfer object.

[0158] Figures 2(a) to 2(c) and Figures 3(a) to 3(b) are process diagrams illustrating the manufacturing method of a printed object in this disclosure. First, as shown in Figure 2(a), an intermediate transfer medium 10 is prepared. The intermediate transfer medium 10 is the same as the intermediate transfer medium 10 shown in Figure 1 above. Next, as shown in Figure 2(b), an image 25 is formed on the surface of the transfer layer 3 of the intermediate transfer medium 10. Next, as shown in Figure 2(c), the surface of the transfer layer 3 on which the image 25 of the intermediate transfer medium 10 is formed is placed opposite the surface of the object to be transferred 51. Subsequently, as shown in Figure 3(a), heat and pressure are applied to expand the foamy layer 2, and the transfer layer 3 on which the image 25 of the intermediate transfer medium 10 is formed is transferred to the surface of the object to be transferred 51. At this time, as the foamed layer 2 expands, the transfer layer 3 on which the image 25 of the intermediate transfer medium 10 is formed is pressed against the object to be transferred 51, so that the transfer layer 3 on which the image 25 is formed is pressed into the recesses of the uneven surface of the object to be transferred 51. This allows the transfer layer 3 on which the image 25 is formed to be transferred to the recesses of the uneven surface of the object to be transferred 51. Next, as shown in Figure 3(b), the substrate 1 and the expanded foamed layer 2 are peeled off from the transfer layer 3 that has been transferred to the surface of the object to be transferred 51.

[0159] In this disclosure, the above-mentioned intermediate transfer medium is used, and therefore the effects described in "A. Intermediate Transfer Medium" above are achieved.

[0160] 1. Preparation process In the preparation step, an intermediate transfer medium is prepared having, in this order, a base material, a foaming layer containing a foaming agent, and a transfer layer. The intermediate transfer medium is the same as described in "A. Intermediate Transfer Medium" above.

[0161] 2. Image forming process In the image formation process, an image is formed on the surface of the transfer layer of the intermediate transfer medium. The image is preferably formed by an on-demand printing method. The on-demand printing method is the same as described in "A. Intermediate Transfer Medium" above.

[0162] In the case of the thermal transfer method, a thermal transfer sheet is used. The thermal transfer sheet is the same as described in "C. Combination of Intermediate Transfer Medium and Thermal Transfer Sheet" above.

[0163] 3. Transfer process In the transfer process, the surface of the transfer layer on which the image of the intermediate transfer medium is formed is placed opposite the surface of the object to be transferred, and heat and pressure are applied to expand the foamed layer, thereby transferring the transfer layer on which the image of the intermediate transfer medium is formed to the surface of the object to be transferred.

[0164] The heating and pressurizing conditions are set appropriately according to the type of blowing agent, the material of the transfer layer, etc. The heating temperature is preferably higher than the foaming start temperature of the blowing agent, more preferably ±45°C of the maximum foaming temperature of the blowing agent, and even more preferably ±30°C of the maximum foaming temperature of the blowing agent. Specifically, the heating temperature is preferably 80°C to 200°C, more preferably 85°C to 185°C, and even more preferably 90°C to 170°C. The heating time is preferably, for example, 15 seconds to 6 minutes, more preferably 30 seconds to 6 minutes, even more preferably 30 seconds to 4 minutes, and may be 1 minute to 4 minutes.

[0165] The pressurization method is not particularly limited as long as it allows for pressurization while heating. The pressurization conditions are adjusted as appropriate to transfer the transfer layer to the material to be transferred. For heating and pressurization, a heat roll, laminator, iron, heat press, heated drum, etc., may be used.

[0166] The material to be transferred is the same as described in "D. Combination of Intermediate Transfer Medium, Thermal Transfer Sheet, and Material to be Transferred" above.

[0167] 4. Peeling process In the peeling step, the substrate and the expanded foamed layer are peeled off from the transfer layer transferred to the transfer surface of the object to be transferred. This yields a printed image.

[0168] 5.Removal process The method for manufacturing a printed product in this disclosure may include a removal step between the image forming step and the transfer step, in which a peel-off layer is heat-pressed onto the surface of the transfer layer of an intermediate transfer medium, and then a portion of the transfer layer is removed by the peel-off layer.

[0169] Figures 10(a) to 10(d) are process diagrams illustrating the image formation and removal processes in the method for manufacturing a printed material according to this disclosure. First, as shown in Figure 10(a), a thermal transfer sheet 10F is prepared. The thermal transfer sheet 20F has a support 21f, a colorant layer 22 (yellow colorant layer 22Y, magenta colorant layer 22M, cyan colorant layer 22C) and a peel-off layer 26 arranged on the same surface of the support 21f. As described above, the peel-off layer 26 is a layer for removing a portion of the transfer layer of the intermediate transfer medium. Next, as shown in Figure 10(b), an image 25 is formed on the surface of the transfer layer 3 of the intermediate transfer medium 10 using the colorant layer 22 of the thermal transfer sheet 20F. Subsequently, as shown in Figure 10(c), the thermal transfer sheet 20F and the intermediate transfer medium 10 are placed on top of each other so that the surface of the peel-off layer 26 of the thermal transfer sheet 20F and the surface of the transfer layer 3 of the intermediate transfer medium are in contact. In this state, the thermal transfer sheet 20F is locally heated from the side of the support 21f of the thermal transfer sheet 20F by the thermal head 29, and the surface of the peel-off layer 26 of the thermal transfer sheet 20F is pressed against the surface of the transfer layer 3 of the intermediate transfer medium by the thermal head 29 and platen roller (not shown). Since the heated and pressed portion 26A of the peel-off layer 26 adheres closely to the surface of the transfer layer 3 of the intermediate transfer medium 10, the above portion 26A of the peel-off layer 26 becomes adhered to the transfer layer 3. On the other hand, the portion of the peel-off layer 26 other than the above portion 26A is not heated and pressed against the transfer layer 3, and therefore does not adhere to the transfer layer 3. Next, as shown in Figure 10(d), the portion 3A of the transfer layer 3 corresponding to the above portion 26A of the peel-off layer 26 is removed by peeling the thermal transfer sheet 20F from the intermediate transfer medium 10. In this case, since the foamed layer 2 and the transfer layer 3 are detachable in the intermediate transfer medium 10, the foamed layer 2 remains in the intermediate transfer medium 10. The portion 3A of the transfer layer 3 corresponding to the portion 26A of the peel-off layer 26 may be located in an area on the surface of the transfer layer 3 of the intermediate transfer medium 10 where the image 25 has not been formed, or in an area where transfer to the object to be transferred is not desired. Next, although not shown in the figures, in the transfer step, the portion 3B of the transfer layer 3 that was not removed in the removal step is transferred to the transfer surface of the object to be transferred.

[0170] When performing a removal process, by removing a portion of the transfer layer, only the necessary area of ​​the transfer layer of the intermediate transfer medium can be transferred to the transfer surface of the object to be transferred during the transfer process after the removal process. Alternatively, in a printed object, a desired area of ​​the object to be transferred can be prevented from being covered by the transfer layer.

[0171] Furthermore, when performing a removal process, a melt layer formation process may be performed between the image formation process and the removal process to form a melt layer on the surface of the transfer layer of the intermediate transfer medium in the removal region where the transfer layer is to be removed. In this case, the removal region can be cleanly removed in the removal process.

[0172] The molten layer is not particularly limited as long as it can be melted or softened by heating and formed on the transfer layer. For example, a heat seal layer or a molten transfer type colorant layer can be used.

[0173] In the molten layer formation process, the molten layer only needs to be formed in at least a portion of the removal area. The molten layer may be formed in an area smaller than the removal area, in the same area as the removal area, or in an area larger than the removal area. Furthermore, the molten layer may be formed in a pattern.

[0174] When performing the removal process, the heat transfer sheet is not limited to the heat transfer sheet 20F described above. For example, a heat transfer sheet in which a colorant layer is arranged on one side of the support and a heat transfer sheet in which a peel-off layer is arranged on one side of the support may be used in combination. Alternatively, for example, a heat transfer sheet in which a colorant layer, a heat seal layer, and a peel-off layer are arranged in a plane order on one side of the support may be used, or a heat transfer sheet in which a colorant layer, a molten transfer type colorant layer, and a peel-off layer are arranged in a plane order on one side of the support may be used.

[0175] 6. Block layer formation process The method for manufacturing a printed product in this disclosure may include a block layer formation step between the image forming step and the transfer step, in which a block layer is formed on the surface of the transfer layer of the intermediate transfer medium in an area where no image has been formed.

[0176] Figures 11(a) to 11(d) and 12(a) to 12(b) are process diagrams illustrating the image formation process, block formation process, transfer process, and peeling process in the method for manufacturing a printed material according to this disclosure. First, as shown in Figure 11(a), a thermal transfer sheet 10G is prepared. The thermal transfer sheet 20G has a support 21g and a colorant layer 22 (yellow colorant layer 22Y, magenta colorant layer 22M, cyan colorant layer 22C) and a block layer 27 arranged on the same surface of the support 21g. Next, as shown in Figure 11(b), an image 25 is formed on the surface of the transfer layer 3 of the intermediate transfer medium 10 using the colorant layer 22 of the thermal transfer sheet 20G. Subsequently, as shown in Figures 11(c) to 11(d), the thermal transfer sheet 20G and the intermediate transfer medium 10 are superimposed so that the surface of the block layer 27 of the thermal transfer sheet 20G and the surface of the transfer layer 3 of the intermediate transfer medium face each other. In this state, the thermal transfer sheet 20G is locally heated by the thermal head 29 from the side of the support 21g of the thermal transfer sheet 20G. This transfers the heated portion 27A of the block layer 27 to the surface of the transfer layer 3 of the intermediate transfer medium 10. The portion 27A of the block layer 27 is located in an area on the surface of the transfer layer 3 of the intermediate transfer medium 10 where the image 25 has not been formed. Next, as shown in Figure 12(a), the intermediate transfer medium 10 and the object to be transferred 51 are superimposed so that the surface of the transfer layer 3 of the intermediate transfer medium 10 and the transfer surface of the object to be transferred 51 face each other. In this state, the intermediate transfer medium 10 and the object to be transferred 51 are heated and pressurized. At this time, as shown in Figure 12(b), the foaming agent in the foamed layer 2 foams and the foamed layer 2 expands, transferring the transfer layer 3 of the intermediate transfer medium 10 to the transfer surface of the object to be transferred 51. At this time, the block layer 27A transferred onto the transfer layer 3 of the intermediate transfer medium 10 functions as a masking member, and only the portion 3C of the transfer layer 3 that does not overlap with the block layer 27A is transferred to the transfer surface of the object to be transferred 51.

[0177] When performing a block layer formation process, by forming a block layer on a portion of the surface of the transfer layer of the intermediate transfer medium, only the necessary area of ​​the transfer layer of the intermediate transfer medium can be transferred to the transfer surface of the object to be transferred during the transfer process after the block layer formation process.

[0178] When performing the block layer formation process, the heat transfer sheet is not limited to the heat transfer sheet 20G described above. For example, a heat transfer sheet with a colorant layer on one side of the support and a heat transfer sheet with a block layer on one side of the support may be used in combination. Alternatively, for example, a heat transfer sheet in which a colorant layer, a heat seal layer, and a block layer are arranged in a sequential manner on one side of the support may be used.

[0179] 7.Second adhesive layer formation process The method for manufacturing a printed object in this disclosure may include a second adhesive layer forming step between the image forming step and the transfer step, in which a second adhesive layer is formed on the surface of the transfer layer of the intermediate transfer medium in the region where the image is formed. In this case, in the transfer step, the transfer layer is transferred to the transfer surface of the object to be transferred via the second adhesive layer, thereby improving the adhesion of the transfer layer.

[0180] Figures 13(a) to 13(c) and 14(a) to 14(b) are process diagrams illustrating the image formation process, second color layer formation process, transfer process, and peeling process in the method for manufacturing a printed object according to this disclosure. First, as shown in Figure 13(a), an image 25 is formed on the surface of the transfer layer 3 of the intermediate transfer medium 10. Next, as shown in Figure 13(b), a second adhesive layer 28 is formed on the surface of the transfer layer 3 of the intermediate transfer medium 10 in the area where the image 25 is formed. Next, as shown in Figure 13(c), the intermediate transfer medium 10 and the object to be transferred 51 are superimposed so that the surface of the transfer layer 3 of the intermediate transfer medium 10 and the transfer surface of the object to be transferred 51 face each other. In this state, the intermediate transfer medium 10 and the object to be transferred 51 are heated and pressurized. At this time, as shown in Figure 14(a), the foaming agent in the foamed layer 2 foams, and the foamed layer 2 expands, thereby transferring the transfer layer 3 of the intermediate transfer medium 10 to the transfer surface of the transfer target 51 via the second adhesive layer 28. Next, as shown in Figure 14(b), the substrate 1 and the expanded foamed layer 2 are peeled off from the transfer layer 3 that has been transferred to the transfer surface of the transfer target 51. As a result, the expanded foamed layer 2 and the transfer layer 3 are separated, and only the transfer layer 3 is transferred to the transfer surface of the transfer target 51.

[0181] In the second adhesive layer formation step, as shown in Figure 14(a), the second adhesive layer 28 may be formed only in the region where the image 25 is formed on the surface of the transfer layer 3 of the intermediate transfer medium 10. Alternatively, in the second adhesive layer formation step, as shown in Figure 14(b), the second adhesive layer 28 may be formed in a region slightly larger than the region where the image 25 is formed on the surface of the transfer layer 3 of the intermediate transfer medium 10. In either case, during the transfer step, only the portion of the transfer layer that overlaps with the second adhesive layer is transferred to the transfer surface of the object to be transferred.

[0182] When forming a second adhesive layer on the surface of the transfer layer of an intermediate transfer medium in an area slightly larger than the area where the image is formed, the distance d from the edge of the area where the image is formed to the edge of the second adhesive layer is appropriately selected depending on the size of the area where the image is formed, the printer, and the application, but may be, for example, 30 μm or more and 450 μm or less. Specifically, the above distance d may be 1 dot or more and 5 dots or less in a 300 dpi or 600 dpi printer, or it may be 1 dot or 2 dots. By forming the second adhesive layer in an area slightly larger than the area where the image is formed in this way, image misalignment during transfer can be tolerated.

[0183] As the second adhesive layer, the heat seal layer described above can be used.

[0184] G. Image-based intermediate transfer medium The image-bearing intermediate transfer medium in this disclosure has the above-described intermediate transfer medium, wherein the transfer layer of the intermediate transfer medium has an image. The image-bearing intermediate transfer medium in this disclosure is obtained after the image formation step in the above-described method for manufacturing a printed product.

[0246] [Rating 1] Prints were prepared using intermediate transfer media and thermal transfer sheets, and their transferability and surface condition were evaluated.

[0247] (1) Production of prints (1-1) Primary Transcription First, a receiving paper for the "DP-DS820" dye-sublimation digital photo printer manufactured by Dai Nippon Printing Co., Ltd. was prepared, and the receiving layer on the surface of the receiving paper was wiped off with a solvent (toluene / MEK=1 / 1). Next, a weak adhesive (Fujikura Chemicals Co., Ltd., LKG-1104) was applied to the wiped surface of the receiving paper so that its dry thickness would be 3 μm, and it was dried at 100°C for 1 minute to form an adhesive layer. Next, the adhesive layer side of the ribbon was bonded to the substrate side of the intermediate transfer medium. Then, using a thermal transfer printer, the colorant layer (Ye, Mg, Cy) and heat seal layer of the thermal transfer sheet were transferred to the receiving layer surface of the intermediate transfer medium under the following conditions to form a 10 cm x 10 cm solid black image.

[0248] <Requirements for thermal transfer printers> • Thermal head: F3589 (manufactured by Toshiba Hokuto Electronics Co., Ltd.) • Average resistance of heating element: 5015Ω Printing voltage: 19V • Main scanning resolution: 300 dpi (dots per inch) Sub-scanning direction resolution: 300dpi Line speed: 6.0 msec. / line • Pulse duty cycle: 85% • Gradient value: 255 / 255 (maximum energy gradient)

[0249] (1-2) Secondary transfer (a) Examples 1-8, Comparative Examples 1-2 First, the intermediate transfer medium on which the image was formed was peeled off the receiving paper. Next, the transfer layer surface on which the image was formed of the intermediate transfer medium was placed on top of the cloth shown below, and the press was pressed using the press machine shown below with a load of 320 g / cm². 2 The image was transferred to the cloth by heating and pressurizing it at a temperature of 160°C for 180 seconds. After cooling, the expanded foamed layer and substrate were peeled off from the transfer layer on the cloth. This obtained the printed material. • Fabric: 3.5 oz T-shirt (white), manufactured by Toms Co., Ltd., 100% polyester, arithmetic mean height Sa of the transfer surface: 50.1 μm • Press machine: Manual iron press machine, Kabuto PCA-3223, manufactured by Europort Co., Ltd.

[0250] (b) Reference example The image-side of the direct printing medium on which the image was formed was placed over the aforementioned cloth, and a full-surface print of 10cm x 10cm was performed using a thermal transfer printer under the following conditions. This resulted in the obtained print. Since a thermal head was used for secondary transfer, this method is referred to as direct printing and is presented as a reference example.

[0251] <Requirements for thermal transfer printers> • Thermal head: F3589 (manufactured by Toshiba Hokuto Electronics Co., Ltd.) • Average resistance of heating element: 5015Ω Printing voltage: 19V • Main scanning resolution: 300 dpi (dots per inch) Sub-scanning direction resolution: 300dpi Line speed: 6.0 msec. / line • Pulse duty cycle: 85% • Tone value: Image (sublimation) 255 / 255 (maximum energy tone)

[0252] (2) Transferability The printed material was visually inspected to confirm that the image had been transferred to all recessed and raised areas on the fabric surface. A: The image is transferred across the entire surface of the fabric, regardless of any recesses or protrusions. B: There are areas on the fabric surface that have not been transferred (white areas appear).

[0253] (3) Surface condition The printed material was visually observed, and the discrepancy between the printed area and the T-shirt fabric was evaluated. A: The image is formed along the contours of the fabric, making use of the fabric's material (no sense of incongruity). B: There are inconsistencies in shading (transfer inconsistencies) and glossy areas (giving the appearance of a sticker), and the printed area looks unnatural compared to the fabric.

[0254] [Table 1]

[0255] In Examples 1-8, prints were produced using an intermediate transfer medium having a foamed layer, and after secondary transfer, the expanded foamed layer was peeled off together with the substrate, resulting in good transferability and surface condition. On the other hand, in Comparative Examples 1-2, the intermediate transfer medium did not have a foamed layer, resulting in poor transferability and surface condition. In the reference example, a thermal head was used for secondary transfer, resulting in insufficient heat and pressure during secondary transfer, leading to poor transferability and surface condition.

[0256] (4) Arithmetic mean height Sa The Sa of the transfer surface of the cloth used to produce the print and the Sa of the printed area of ​​the print in Example 3 were measured in accordance with ISO 25178:2012 using a shape measuring laser microscope "VK-X150" manufactured by Keyence Corporation. The measurement range was 1070 μm × 1400 μm, and the magnification was 10x. When manufacturing the print, two peeling methods were performed: peeling method 1, which peels the cloth from the substrate of the intermediate transfer medium and the foamed layer after expansion, after secondary transfer; and peeling method 2, which peels the substrate of the intermediate transfer medium and the foamed layer after expansion from the cloth after secondary transfer. When determining the ratio of Sa2 / Sa1, the Sa value of the transfer surface of the cloth was used as Sa1.

[0257] [Table 2]

[0258] Since Examples 5-8 use the same foamed layer as Example 3, it is expected that the results will be the same as in Example 3.

[0259] [Rating 2] Prints were prepared using intermediate transfer media and thermal transfer sheets, and their transferability and surface condition were evaluated.

[0260] (1) Production of prints (1-1) Primary Transcription First, coated paper (Daio Paper Corporation, iCOAT SAU 186.1, 165 μm thick) was prepared as a support layer for the release agent. A weak adhesive (Fujikura Chemicals Co., Ltd., LKG-1104) was applied to one side of the coated paper so that its dry thickness was 3 μm, and it was dried at 100°C for 1 minute to form a weak adhesive layer (resin layer) and obtain a release agent. Next, the weak adhesive layer (resin layer) side of the release agent was bonded to the substrate side of the intermediate transfer medium. This obtained an intermediate transfer medium with a release agent. Next, using a thermal transfer printer, the colorant layer (Ye, Mg, Cy) and heat seal layer of the thermal transfer sheet were transferred to the receiving layer surface of the intermediate transfer medium under the following conditions to form a 10 cm x 10 cm solid black image. In Example 10, under the following conditions, the colorant layer (Ye, Mg, Cy) of the heat transfer sheet was transferred to the receiving layer surface of the intermediate transfer medium to form a 10cm x 10cm solid black image, and then the opacity layer and heat seal layer were sequentially transferred onto the solid black image.

After cooling, the expanded foamed layer and substrate were peeled off from the transfer layer on the cloth. This obtained the printed material. • Fabric: 3.5 oz T-shirt (white), manufactured by Toms Co., Ltd., 100% polyester, arithmetic mean height Sa of the transfer surface: 50.1 μm • Press machine: Manual iron press machine, Kabuto PCA-3223, manufactured by Europort Co., Ltd.
