[Diagram 3] FIG. 1 is a schematic diagram of a lamination process in which a high-hardness roller having a surface Shore D hardness of 40 or more is used as a contact member according to the present invention. [Figure 4] Cross-section of printed matter [Diagram 5] Cross-section of laminate material [Figure 6] Schematic diagram of an example of a lamination process DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] The present invention will be described in detail below. In this application, the symbol "to" is used to mean that the numerical values ​​before and after it are included as a lower limit and an upper limit.

[0027] [Laminate manufacturing system] 1 is a configuration diagram of a laminated body manufacturing system 100. The laminated body manufacturing system 100 includes a printing device 110 and a laminating device 120.

[0028] The printing device 110 is a device that forms a printed matter. The printing device 110 is, for example, an inkjet printing device that uses ink, an electrophotographic printing device that uses toner, or the like. The printing device 110 may be a conventionally known device. The printed matter formed by the printing device 110 has a recording medium and an image portion that contains a component derived from the ink or toner.

[0029] The laminating device 120 is a device that layers a laminate material on a printed matter. The laminate material has a laminate film layer and an adhesive layer. The laminating device 120 includes a contact member that layers the laminate material on the printed matter. The contact member is brought into contact with the laminate film layer. The contact member layers the laminate material on the printed matter so as to cover the image portion with the adhesive layer. The Shore D hardness of the surface of the contact member that contacts the laminate film layer is 40 or more.

[0030] Details of the printed matter, laminating material, contact members, etc. will be described later.

[0031] The laminate manufacturing system 100 may be an in-line type or an offline type. In the in-line type, the printing device 110 and the laminating device 120 are integrated with each other. In the offline type, the printing device 110 and the laminating device 120 are separate from each other.

[0032] [Outline of laminate manufacturing method] The method for producing a laminate of the present invention includes a laminating step of laminating a laminate material on a printed material.

[0033] The printed matter has a recording medium and an image area. The image area contains components derived from ink or toner. The height of the printed matter is not constant due to the presence or absence of an image area, differences in the height of the image area, etc. The maximum height of the image area is 5 μm or more. Since the maximum height of the image area of ​​the printed matter is 5 μm or more, a relief effect is likely to occur when the printed matter is laminated by a conventional method.

[0034] The laminate material includes an adhesive layer and a laminate film layer. The laminate material is laminated on the printed matter such that the adhesive layer covers the image portion of the printed matter. The total thickness of the laminate film layer and the adhesive layer is greater than the maximum height of the image portion.

[0035] The present invention uses a contact member in the lamination process. The contact member is a member that contacts the laminate film layer of the laminate material. The contact member according to the present invention has high hardness. Specifically, the contact member according to the present invention has a surface that contacts the laminate film layer with a Shore D hardness of 40 or more.

[0036] FIG. 2 is a schematic diagram of a lamination process when a low-hardness roller with a surface Shore D hardness of less than 40 is used as a conventional contact member 40. In FIG. 2, the printed matter 3 has a recording medium 32 and an image portion 31. The laminate material 2 has an adhesive layer 22 and a laminate film layer 21. Arrow A indicates the conveying direction of the printed matter 3. Arrow B indicates the rotating direction of the contact member 40 (low-hardness roller). When the low-hardness roller presses the printed matter 3 and the laminate material 2, it deforms to follow the shape of the surface of the printed matter 3. Therefore, a laminate 1 formed using a low-hardness roller as the contact member 40 has a relief-like appearance on the surface.

[0037] FIG. 3 is a schematic diagram of a lamination process when a high-hardness roller with a surface Shore D hardness of 40 or more is used as the contact member 40 according to the present invention. In FIG. 3, the printed matter 3 has a recording medium 32 and an image part 31. The laminate material 2 has an adhesive layer 22 and a laminate film layer 21. Arrow A indicates the conveying direction of the printed matter 3. Arrow B indicates the rotating direction of the contact member 40 (high-hardness roller). The high-hardness roller is not easily deformed when the printed matter 3 and the laminate material 2 are pressed, so that the image part 31 can be pushed into the adhesive layer 22. As a result, the adhesive layer 22 absorbs the process difference of the printed matter 3, and the surface of the laminate is smoothed. Therefore, the laminate 1 formed using the high-hardness roller as the contact member 40 has a reduced relief feeling on the surface.

[0038] [Printed material] 4 is a cross-sectional view of the printed matter 3. The printed matter 3 has a recording medium 32 and an image area 31.

[0039] The type of recording medium 32 is not particularly limited, and may be, for example, plain paper, coated paper, art paper, inkjet paper, inkjet glossy paper, cardboard, wood, plastic, glass, metal, etc. The thickness of the recording medium 32 is not particularly limited.

[0040] The recording medium 32 may be coated paper having a thickness of 100 μm or more. Coated paper having a thickness of 100 μm or more is difficult to deform and is therefore prone to creating a sense of relief, but the present invention reduces the sense of relief.

[0041] The image portion 31 contains components derived from ink or toner. The components derived from ink include, for example, color materials, resins, gelling agents, etc. The image portion 31 containing components derived from ink is composed of, for example, a cured product of ink. The components derived from toner include, for example, color materials, resins, inorganic particles, etc. The image portion 31 containing components derived from toner is composed of, for example, a fused product of toner.

[0042] The image area 31 may contain a component derived from the ultraviolet curable ink. The component derived from the ultraviolet curable ink is, for example, an ultraviolet curable resin. The image area 31 containing the component derived from the ultraviolet curable ink is likely to become taller as the ultraviolet curable resin hardens. Therefore, if the image area 31 contains a component derived from the ultraviolet curable ink, a relief effect is likely to occur, but the present invention reduces the relief effect.

[0043] The image area 31 may contain a component derived from the gelling agent-containing ink. The component derived from the gelling agent-containing ink is, for example, a gelling agent. The image area 31 containing a component derived from the gelling agent-containing ink is likely to be high because the gelling agent makes it difficult for the ink to spread. Therefore, if the image area 31 contains a component derived from the gelling agent-containing ink, a relief effect is likely to occur, but the present invention reduces the relief effect.

[0044] In the present invention, the maximum height of the image portion 31 is 5 μm or more. If the maximum height of the image portion 31 is 5 μm or more, a relief effect is likely to occur, but the present invention reduces the relief effect. Since the present invention can reduce the relief effect, the maximum height of the image portion 31 may be 10 μm or more. In the case of the image portion 31 formed by curing ultraviolet curable ink, for example, the height of the image portion 31 is maximum in the secondary color portion. The maximum height of the image portion 31 is, for example, 15 μm or less.

[0045] When the printed matter 3 is composed only of the recording medium 32 and the image portion 31, in the area where the image portion 31 is present, the combined height of the recording medium 32 and the image portion 31 is the height of the printed matter 3. In the area where the image portion 31 is not present, the thickness of the recording medium 32 is the height of the printed matter 3.

[0046] The printed matter 3 may be a sheet or a long piece.

[0047] [Laminate material] 5 is a cross-sectional view of the laminate material 2. The laminate material 2 has a laminate film layer 21 and an adhesive layer 22.

[0048] The type of the laminate film layer 21 is not particularly limited, but may be, for example, a plastic film. Examples of materials for the plastic film include polypropylene (PP), polyethylene terephthalate (PET), nylon, etc. The plastic film may be a stretched one.

[0049] The material of the adhesive layer 22 is not particularly limited, but may be, for example, ethylene-vinyl acetate (EVA) copolymer resin, acrylic resin, or the like.

[0050] In the present invention, the total thickness of the laminate film layer 21 and the adhesive layer 22 is greater than the maximum height of the image area 31. This reduces the sense of relief. When the laminate material 2 is composed of only the laminate film layer 21 and the adhesive layer 22, the total thickness of the laminate film layer 21 and the adhesive layer 22 is equal to the thickness of the laminate material 2.

[0051] The thickness of the laminate film layer 21 is not particularly limited, but is preferably 12 μm or more. When the thickness of the laminate film layer 21 is 12 μm or more, the relief feeling is more likely to be reduced. The thickness of the laminate film layer 21 may be 30 μm or less. When the thickness of the laminate film layer 21 is 30 μm or less, the relief feeling is easily generated, but the relief feeling is reduced by the present invention.

[0052] The thickness of the adhesive layer 22 is not particularly limited, but is, for example, 12 to 30 μm. In order to further reduce the relief effect, it is preferable that the thickness of the adhesive layer 22 is greater than the maximum height of the image area 31.

[0053] The laminate film layer 21 may have a glossiness of 80% or more after the lamination process. If the glossiness of the laminate film layer 21 is 80% or more, a relief effect is likely to occur, but the present invention reduces the relief effect. The glossiness is measured at a measurement angle of 60°. The glossiness can be measured, for example, by a gloss meter GM-60S (manufactured by Konica Minolta).

[0054] The laminate material 2 may be in the form of a sheet or a long piece.

[0055] [Lamination process] FIG. 6 is a schematic diagram of an example of a lamination process.

[0056] In the present invention, in the lamination step, the laminate material 2 is laminated on the printed matter 3 so that the image area 31 is covered with the adhesive layer 22 .

[0057] In the present invention, a contact member 40 is used in the lamination process. The contact member 40 is a member that comes into contact with the laminate film layer 21 of the laminate material 2.

[0058] The contact member 40 according to the present invention has a Shore D hardness of 40 or more on the surface that contacts the laminate film layer 21. The contact member 40 having a Shore hardness of 40 or more is less likely to deform when pressure is applied to the printed matter 3 and the laminate material 2. Therefore, the present invention using such a contact member 40 can make the image area 31 bite into the adhesive layer 22, thereby reducing the relief effect on the surface of the laminate 1. The Shore D hardness is preferably 50 or more. The Shore D hardness can be measured using a Shore hardness tester Type D specified in JIS B 7727.

[0059] The contact member 40 may be, for example, a roller, a flat plate, a squeegee, or the like. From the viewpoint of productivity, the contact member 40 is preferably a roller. The roller may be used such that the positions of the printed matter 3 and the laminate material 2 change relatively by moving the printed matter 3 and the laminate material 2 without moving the rotation axis of the roller. The roller may be used such that the positions of the printed matter 3 and the laminate material 2 change relatively by moving the rotation axis of the roller without moving the printed matter 3 and the laminate material 2.

[0060] The material of the contact member 40 is, for example, metal, resin, etc. The resin may be rubber such as silicone rubber as long as it has a Shore D hardness of 40 or more. The contact member 40 may be, for example, a metal base body on which a rubber surface layer is formed.

[0061] The force (contact force) with which the contact member 40 is brought into contact with the laminate film layer 21 is preferably within a range of 2 to 20 N / mm.

[0062] In the present invention, it is preferable to heat the laminate material 2 in the lamination step. The temperature to which the laminate material 2 is heated is preferably higher than the melting point of the adhesive layer 22. This makes it easier for the adhesive layer 22 to deform in the lamination step, and makes it easier for the image area 31 to bite into the adhesive layer 22.

[0063] Although there is no particular limitation on the method for heating the laminate material 2, it is preferable to use a heat roller as the contact member 40. The heat roller is a roller that also serves as a heat source for the laminate material 2. By using the heat roller, pressure and heat can be applied efficiently.

[0064] As shown in FIG. 6, the lamination process preferably includes a nipping process and a winding process in this order. In the nipping process, the printed matter 3 and the laminate material 2 are pressed and laminated at the nip portion N by a heat roller (abutment member 40) and an opposing roller 41. The opposing roller 41 is a roller that faces the heat roller. In the winding process, the laminated printed matter 3 and the laminate material 2 are heated and pressed at the winding portion W while being wound around the heat roller. This allows the laminate material 2 to be sufficiently heated and pressed, and the image portion 31 is easily embedded in the adhesive layer 22. The winding portion W shown in FIG. 6 is formed by the tension roller 42 tensioning the printed matter 3 and the laminate material 2 while winding them around the heat roller.

[0065] In the wrapping step, the distance over which the printed matter 3 and the laminate material 2 are wrapped around the heat roller (contact member 40) is preferably 50 mm or more, which allows the laminate material 2 to be heated and pressed more sufficiently.

[0066] In the wrapping step, the pressure with which the printed matter 3 and the laminate material 2 are wrapped around the heat roller (contact member 40) is preferably 50 kPa or more, which allows the laminate material 2 to be pressed more sufficiently.

[0067] As described above, the method for producing a laminated body of the present invention includes a lamination step of laminating a laminate material on a printed matter. The printed matter includes a recording medium and an image portion containing a component derived from an ink or toner. The maximum height of the image portion is 5 μm or more. The laminate material includes a laminate film layer and an adhesive layer. The total thickness of the laminate film layer and the adhesive layer is greater than the maximum height of the image portion. In the lamination step of the production method, a contact member is brought into contact with the laminate film layer to cover the image portion with the adhesive layer, and the laminate material is laminated on the printed matter. The Shore D hardness of the surface of the contact member that contacts the laminate film layer is 40 or more.

[0068] In an embodiment of the method for producing a laminate, the thickness of the adhesive layer is preferably greater than the maximum height of the image area, thereby further reducing the sense of relief.

[0069] In an embodiment of the method for producing a laminate, the image area may contain a component derived from an ultraviolet-curable ink. When the image area contains a component derived from an ultraviolet-curable ink, a relief effect is likely to occur, but the present invention reduces the relief effect.

[0070] In an embodiment of the method for producing a laminate, the image area may contain a component derived from the gelling agent-containing ink. When the image area contains a component derived from the gelling agent-containing ink, a relief effect is likely to occur, but the present invention reduces the relief effect.

[0071] In an embodiment of the method for producing a laminate, the maximum height of the image area may be 10 μm or more. When the maximum height of the image area is 10 μm or more, a sense of relief is likely to occur, but the sense of relief is reduced by the present invention.

[0072] In an embodiment of the method for producing a laminate, the surface of the contact member preferably has a Shore D hardness of at least 50. This further reduces the sense of relief.

[0073] In a preferred embodiment of the method for producing a laminate, the laminating material is heated in the laminating step, thereby further reducing the sense of relief.

[0074] In an embodiment of the method for producing a laminated body, the temperature to which the laminate material is heated in the laminating step is preferably higher than the melting point of the adhesive layer, thereby further reducing the sense of relief.

[0075] In an embodiment of the method for producing a laminate, from the viewpoint of productivity, the contact member is preferably a roller.

[0076] In an embodiment of the method for producing a laminate, the contact member is preferably a heat roller, which allows pressure and heat to be applied efficiently.

[0077] In an embodiment of the method for manufacturing a laminate, the lamination step preferably includes a nipping step and a wrapping step in this order. In the nipping step, the heat roller and an opposing roller opposing the heat roller are used to pressurize and laminate the printed matter and the laminate material. In the wrapping step, the laminated printed matter and the laminate material are heated and pressed while being wrapped around the heat roller. This further reduces the relief effect.

[0078] In an embodiment of the method for producing a laminate, the distance over which the printed matter and the laminate material are wound around the heat roller is preferably 50 mm or more, thereby further reducing the sense of relief.

[0079] In an embodiment of the method for producing a laminate, the pressure at which the printed matter and the laminate material are wound around the heat roller is preferably 50 kPa or more, thereby further reducing the sense of relief.

[0080] In an embodiment of the method for producing a laminate, the thickness of the laminate film layer may be 30 μm or less. When the thickness of the laminate film layer is 30 μm or less, a relief feeling is easily generated, but the relief feeling is reduced by the present invention.

[0081] In an embodiment of the method for producing a laminate, the recording medium may be a coated paper having a thickness of 100 μm or more. A coated paper having a thickness of 100 μm or more is difficult to deform and is therefore prone to creating a sense of relief, but the present invention reduces the sense of relief.

[0082] In an embodiment of the method for producing a laminate, the gloss of the laminate film layer after the lamination step may be 80% or more. When the gloss of the laminate film layer is 80% or more, a relief effect is easily generated, but the relief effect is reduced by the present invention.

[0083] The laminate manufacturing system of the present invention includes a printing device that forms a printed matter, and a laminating device that laminates a laminate material on the printed matter. The printed matter has a recording medium and an image portion that contains a component derived from ink or toner. The maximum height of the image portion is 5 μm or more. The laminate material has a laminate film layer and an adhesive layer. The total thickness of the laminate film layer and the adhesive layer is greater than the maximum height of the image portion. The laminating device includes a contact member that contacts the laminate film layer to cover the image portion with the adhesive layer and laminates the laminate material on the printed matter. The Shore D hardness of the surface of the contact member that contacts the laminate film layer is 40 or more.

[0084] In an embodiment of the laminate manufacturing system, the printing device and the laminating device may be separate devices.

[0085] In an embodiment of the laminate manufacturing system, the printing device and the laminating device may be integrated together. EXAMPLES

[0086] The present invention will be described in detail below with reference to examples, but the present invention is not limited thereto. In the following examples, unless otherwise specified, operations were performed at room temperature (25°C).

[0087] The laminate material used was PERFEX (manufactured by GMP Co., Ltd.), which is composed of the following laminate film layer and adhesive layer. <Laminate film layer> Ingredients: Biaxially oriented polypropylene (OPP: Oriented Polypropylene) Thickness: 12μm <Adhesive layer> Ingredients: Ethylene-vinyl acetate copolymer resin (EVA: Ethylen-Vinyl Acetate) Thickness: 12μm Melting point: 95℃

[0088] The print was produced by forming an image area on a recording medium using an ultraviolet-curable ink containing a gelling agent. The recording medium used was a 138 μm-thick coated paper (OK Topcoat+, manufactured by Oji Paper Co., Ltd.). The image area had a primary color area of ​​cyan, magenta, yellow, and black, and a secondary color area of ​​red, green, and blue. The primary color area was formed using a single color ink of cyan, magenta, yellow, and black, respectively. The secondary color area was formed by appropriately overlapping the inks of cyan, magenta, yellow, and black. The height of the primary color area was 8.3 μm. The height of the secondary color area was 10.9 μm.

[0089] [Example 1] The laminate was laminated on the printed matter using a laminating device equipped with a contact member and an opposing roller to produce a laminate. In Examples 1-1 to 1-5, a SUS heat roller with silicone rubber of different hardness attached thereto was used as the contact member. In Example 1-6, the SUS heat roller was used as the contact member as is. The Shore D hardness of the surface of the heat roller in each Example is as shown in Table I. The Shore D hardness of the surface of the contact member used in Example 1-6 cannot be measured accurately, but is very hard compared to silicone rubber, exceeding 90. Since the material of the surface of the contact member used in Example 1-6 is SUS, which is a rigid body, its Shore D hardness cannot be measured accurately. The temperature of the heat roller was 110°C. In Example 1, only the nipping process was performed, and the winding process was not performed. The contact force of the heat roller in the nipping process was 10 N / mm.

[0090] The laminates thus produced were evaluated for the relief appearance of the primary color portion, the relief appearance of the secondary color portion, and the overall relief appearance based on the following criteria. The evaluation results are shown in Table I.

[0091] [Evaluation Criteria for Feeling of Relief] A: Excellent level with no sense of relief. B: There is a sense of relief when looking closely, but it is at a good level. C: There is some relief, but it is still usable. D: The relief is noticeable and unusable.

[0092] [Table 1]

[0093] [Example 2] Using a laminating device equipped with a contact member and an opposing roller, the laminate material was laminated on the printed matter to produce a laminate. In Example 2, a SUS heat roller with silicone rubber attached was used as the contact member. The Shore D hardness of the surface of the contact member was 40. The temperature of the heat roller was changed as shown in Table II. In Example 2, only the nipping process was performed, and the wrapping process was not performed. The contact force of the heat roller in the nipping process was 10 N / mm.

[0094] The resulting laminate was evaluated for the overall relief appearance based on the above-mentioned criteria, and the evaluation results are shown in Table II.

[0095] [Table 2]

[0096] [Example 3] The laminate material was laminated on the printed matter using a laminating device equipped with a contact member and an opposing roller to produce a laminate. In Example 3, a SUS heat roller with silicone rubber attached was used as the contact member. The Shore D hardness of the surface of the contact member was 40. The temperature of the heat roller was 110°C. In Example 3 (excluding Examples 3-1, 3-7, and 3-13), the winding process was performed after the nipping process. The contact force of the heat roller in the nipping process was 10 N / mm. The distance (winding length) and pressure (winding pressure) at which the printed matter and the laminate material were wound around the heat roller in the winding process were changed as shown in Table III.

[0097] The resulting laminate was evaluated for the overall relief appearance according to the above-mentioned criteria, and the evaluation results are shown in Table III.
