Means for solving the problems
In order to solve the above problems and achieve the object, a decorative structure of the present invention is characterized by comprising: an image layer formed on a surface of the substrate; a transparent layer laminated on the front surface side of the image layer with a material that can transmit light; and a slit layer which is composed of a non-transmissive member, and which has a plurality of slits arranged in parallel and is laminated on the front surface side of the transparent layer.
In the present invention, since the slit layer having many slits formed therein is disposed on the front surface side of the image layer with the transparent layer interposed therebetween, the image of the image layer is observed by visually checking the light passing through the slits. On the other hand, since light passing through the slit is easy to pass through in the direction in which the slit is formed and is difficult to pass through in directions other than the direction in which the slit is formed, it is possible to visually confirm whether or not the light passing through the slit changes depending on the angle at which the image layer is observed. Thus, the visibility of the image layer can be changed by the angle at which the image layer is observed, simply by disposing the slit layer on the front surface side of the image layer, without considering the relative position between the image layer and the slit layer. As a result, the visual effect can be easily obtained.
In the decorative structure, it is preferable that the slit layer is formed in a plurality of directions in which the slits are arranged in parallel.

In the present invention, since the transparent layer is formed of an adhesive and the slit layer is bonded to the image layer by the adhesive forming the transparent layer, the slit layer and the transparent layer can be easily laminated on the image layer. As a result, the visual effect can be obtained easily and at low cost.
In the decorative structure, it is preferable that the image layer is formed by bonding a film to the surface of the base material with an adhesive.
In the present invention, the image layer is formed by bonding the film to the surface of the base material with an adhesive, and therefore the image layer can be easily formed. As a result, the visual effect can be obtained easily and at low cost.
In the decorative structure, it is preferable that a plurality of the transparent layers are stacked.

Detailed Description
Hereinafter, embodiments of the decorative structure of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the embodiment. The components in the following embodiments include components that can be easily replaced by those skilled in the art, or substantially the same components.
[ embodiment ]
Fig. 1 is a plan view of a decorative body decorated with the decorative structure of the embodiment. Fig. 2 is a sectional view a-a of fig. 1. The decorative body 1 shown in the figure is decorated on the surface by the decoration structure of the present embodiment. The decorative body 1 is mainly applied to an article such as a cover of a cellular phone, which is frequently touched by the human eye and has a large effect of improving the appearance by decoration. The decorative structure applied to the decorative body 1 decorates the surface of the substrate 5 by laminating a plurality of layers on the surface 6 of the substrate 5 constituting the decorative body 1.
The plurality of layers laminated on the front surface 6 of the substrate 5 are composed of an image layer 10, a transparent layer 15, and a slit layer 20, the image layer 10 is formed on the front surface of the substrate 5, the transparent layer 15 is laminated on the front surface side of the image layer 10 with a material that can transmit light, and the slit layer 20 is laminated on the front surface side of the transparent layer 15 with a large number of slits 22 (see fig. 4) arranged in parallel.
Fig. 3 is a cross-sectional view B-B of fig. 2, which is an explanatory view of an image layer. The image layer 10 among the plurality of layers laminated on the surface 6 of the base material 5 constitutes an image such as a pattern or a character as a layer to be decorated by the decoration 1, and in the present embodiment, is composed of an adhesive layer 11 and a film 12, and the adhesive layer 11 is composed of an adhesive. Specifically, the film 12 is a non-permeable film-like member such as an aluminum foil, and is formed of, for example, an aluminum vapor-deposited film. The image applied to the garnish 1 is formed by the film 12. That is, the film 12 is formed into an arbitrary image shape, and the desired image decoration is applied to the surface 6 of the substrate 5 by adhering the film 12 to the surface 6 of the substrate 5 with the adhesive constituting the adhesive layer 11.
The adhesive constituting the adhesive layer 11 is formed on the surface 6 of the base material 5 in the same shape as the film 12. That is, the adhesive layer 11 is provided by forming an adhesive in the shape of an image applied to the surface 6 of the substrate 5, and the film 12 formed in the same shape as the adhesive of the adhesive layer 11 is adhered to the surface 6 of the substrate 5 by the adhesive. The image layer 10 is composed of the adhesive layer 11 and the film 12 having the same shape in plan view.
The transparent layer 15 is laminated on the front side of the image layer 10, that is, on the side of the image layer 10 opposite to the substrate 5. The transparent layer 15 is formed of an adhesive, and is formed of a light-transmissive adhesive, similarly to the adhesive layer 11 constituting the image layer 10. In addition, the thickness of the transparent layer 15 is thicker than the thickness of the adhesive layer 11 of the image layer 10.
Further, since the image layer 10 is formed in the shape of an image by the adhesive layer 11 together with the film 12, there is a portion of the surface 6 of the base 5 where the adhesive layer 11 and the film 12 are not provided, and an adhesive for forming the transparent layer 15 laminated on the surface side of the image layer 10 flows into this portion.
The transparent layer 15 is formed by bonding the slit layer 20 laminated on the front surface side of the transparent layer 15 to the image layer 10 with an adhesive constituting the transparent layer 15. Specifically, the slit layer 20 is formed of a film 21, which is an impermeable film member such as an aluminum foil, similarly to the film 12 of the image layer 10, and the transparent layer 15 bonds the film 21 to the image layer 10. The transparent layer 15 has the same shape as the film 21 constituting the slit layer 20 in a plan view, as in the adhesive layer 11 of the image layer 10.
Fig. 4 is a detailed view of section C of fig. 1. The slit layer 20 has a plurality of slits 22 communicating with each other in the thickness direction of the thin film 21, and the plurality of slits 22 are arranged in parallel in the forming direction of the thin film 21. In addition, the slit layer 20 is formed with a direction in which a plurality of slits 22 are arranged in parallel in each of a plurality of regions. Specifically, the slits 22 are formed in the direction perpendicular to each other in the forming direction of the film 21, the slits 22 formed in one direction are formed as vertical slits 23, and the slits 22 formed in the direction perpendicular to the vertical slits 23 are formed as horizontal slits 24.
The longitudinal slits 23 of the plurality of slits 22 and the transverse slits 24 are arranged in parallel in plural numbers to form a partition, and the slit layer 20 has plural partitions. In this way, of the partitions formed by the plurality of slits 22, the partition in which the plurality of vertical slits 23 are arranged in parallel becomes the vertical slit forming portion 26, and the partition in which the plurality of horizontal slits 24 are arranged in parallel becomes the horizontal slit forming portion 27.
The vertical slit forming portions 26 and the horizontal slit forming portions 27 are each formed in a substantially square shape in plan view, and the vertical slit forming portions 26 and the horizontal slit forming portions 27 are alternately formed in the slit layer 20 so as to be shifted from each other in the forming direction of the film 21. In other words, the slit layer 20 has a plurality of vertical slit forming portions 26 and horizontal slit forming portions 27 formed in a checkered pattern. In this way, the slit layer 20 is formed with a plurality of directions in which the plurality of slits 22 are arranged in parallel by forming a plurality of vertical slit forming portions 26 in which the plurality of vertical slits 23 are arranged in parallel and the plurality of horizontal slit forming portions 27 in which the plurality of horizontal slits 24 are arranged in parallel.
Next, a method of manufacturing the decorative body 1 decorated with the decorative structure of the present embodiment will be described. In the decorative structure of the present embodiment, the adhesive constituting the adhesive layer 11 and the transparent layer 15 is printed by, for example, an ink jet printer 100 (see fig. 5), thereby forming the adhesive layer 11 and the transparent layer 15 in a desired shape.
Fig. 5 is a schematic configuration diagram showing a schematic configuration of an inkjet printer used in the decorative structure of the embodiment. The inkjet printer 100 used for decorating the decorative body 1 includes a Y-bar 101, an ink cartridge 102, a carriage 103, and a control device 104, which are provided in the main scanning direction. The ink cartridge 102 is a member that stores ink to be ejected to a medium (the decorative body 1 in the present embodiment) M, and includes at least an adhesive layer ink cartridge 106. The adhesive layer cartridge 106 is a member that stores ink for forming the adhesive layer 11 and the transparent layer 15, that is, adhesive layer ink as ink whose curing degree is changed by exposure.
As the adhesive layer ink, for example, "IJPrimer PR-100 (product name)" manufactured by yum engineering of japan as an inkjet UV primer can be used. The ink composition of the "IJ Primer PR-100" is, for example, an acrylate (80% -90%), an initiator (5% -15%), and an additive (0.1% -5%). That is, in the present embodiment, the adhesive layer ink is used as an adhesive agent constituting the adhesive layer 11 and the transparent layer 15.
The carriage 103 is movable in the main scanning direction along the Y-bar 101. The carriage 103 is controlled to move in a direction (main scanning direction) orthogonal to a printing conveyance direction (sub scanning direction) of the medium M. The carriage 103 includes a holder 107 and a pair of ultraviolet lamps 108 as exposure portions provided on both sides of the holder 107 in the main scanning direction.
The ejection unit 109 is disposed on a holder 107 included in the carriage 103. The ejection unit 109 can eject the adhesive layer ink stored in the adhesive layer ink cartridge 106 to the medium M. The ejection unit 109 includes, for example, a print head that ejects ink while facing the medium M, various ink flow paths that connect the ink cartridge 102 and the print head, and a regulator and a pump provided in the ink flow paths.
Here, the print head includes at least a head portion that ejects the adhesive layer ink, and is connected to the adhesive layer ink cartridge 106 via a flow path of the adhesive layer ink. The ejection section 109 ejects the adhesive layer ink or the like of the adhesive layer cartridge 106 toward the medium M in an inkjet manner from each head of the print head by driving the pump in a predetermined ejection amount.
Each ultraviolet lamp 108 can expose ink ejected onto the medium M. Each ultraviolet lamp 108 is composed of, for example, an LED module capable of irradiating ultraviolet rays. The inkjet printer 100 includes a conveying device for relatively moving the medium M in a printing and conveying direction (sub-scanning direction) with respect to the carriage 103 together with a platen, a table, and the like on which the medium M is placed.
The control device 104 is a device for controlling each part of the inkjet printer 100 including the ejection unit 109, each ultraviolet lamp 108, and the like. The control device 104 is functionally and conceptually configured to include an ejection control section 104a, an exposure control section 104b, a pattern conversion section 104c, and the like. The control device 104 is configured by hardware such as an arithmetic device and a memory, and a program for realizing predetermined functions of the hardware.
The ejection control section 104a included in the control device 104 is a member for controlling a pump or the like of the ejection section 109 and controlling an ejection amount, an ejection timing, an ejection period, and the like of ink ejected from the ejection section 109. The exposure control unit 104b is a member for controlling the ultraviolet lamps 108 and the like, and controlling the intensity, exposure timing, exposure period, and the like of the ultraviolet rays irradiated from the ultraviolet lamps 108. The pattern conversion unit 104c is a means for setting an ejection control amount and an exposure control amount based on input information input from an input device 200 such as a PC or various terminals connected to the control device 104 in a wired/wireless manner.
The pattern conversion unit 104c receives, as input information, for example, image information input via the input device 200 or the like, that is, desired graphics (characters, patterns, and the like) to be decorated on the decorative body 1, image information in a form in which a large number of slits 22 are formed in the slit layer 20, and the like. The pattern conversion unit 104c generates a pattern of the adhesive layer 11 to be a desired pattern to be printed on the garnish 1 based on the input information, and converts the pattern into an ejection control amount and an exposure control amount that can realize the generated print pattern. Then, the discharge control unit 104a controls the discharge of the discharge unit 109 based on the discharge control amount calculated by the pattern conversion unit 104c, and the exposure control unit 104b controls the exposure of each ultraviolet lamp 108 based on the exposure control amount calculated by the pattern conversion unit 104 c.
The ink jet printer 100 thus configured reciprocates the carriage 103 in the main scanning direction with respect to the medium M under the control of the control device 104, and ejects ink with a predetermined print width onto the print surface of the medium M by the ejection section 109. Then, the inkjet printer 100 suppresses spreading of the ink applied to the medium M by irradiating each ultraviolet lamp 108 with relatively weak ultraviolet rays at predetermined timing and performing exposure, and performs temporary curing (constraint (ピニング) exposure) in which the dot diameter and the like are controlled and penetration is suppressed, in accordance with the control of the control device 104. Further, the ink jet printer 100 irradiates the temporarily cured ink with relatively strong ultraviolet rays and performs exposure, thereby performing permanent curing (キュアリング) exposure) for completely curing the ink.
The inkjet printer 100 relatively moves the medium M in the print conveyance direction (sub-scanning direction) with respect to the carriage 103 according to the above-described predetermined print width, and repeats the operation, printing a predetermined pattern. During this period, the ejection control section 104a of the control device 104 controls the ejection amount, ejection timing, ejection period, and the like of the ink ejected from the ejection section 109, and the exposure control section 104b controls the intensity of the ultraviolet rays irradiated from the respective ultraviolet lamps 108, the tie/cure exposure timing, the tie/cure exposure period, and the like. Thus, the inkjet printer 100 can print a desired pattern by adjusting the shape, thickness, area, diameter, density, and the like of the adhesive layer 11 and the transparent layer 15 according to the print pattern generated by the pattern converting section 104 c.
When decorating the decorative body 1 with the decorative structure of the present embodiment, first, the adhesive layer 11 of the image layer 10 is formed on the surface 6 of the base material 5 constituting the decorative body 1 using the ink jet printer 100. That is, an adhesive layer ink used as an adhesive constituting the adhesive layer 11 is printed on the surface 6 of the base material 5 in the shape of an image shown by the image layer 10 using the ink jet printer 100. The film 12 is adhered to the adhesive layer 11 in a state of being temporarily cured after the ink is applied to the adhesive layer.
The film 12 constituting the image layer 10 together with the adhesive layer 11 is bonded to the adhesive layer 11 using a so-called transfer foil in which a transfer film such as an aluminum foil is deposited as the film 12 on a transfer film. Specifically, the transfer foil is bonded to the adhesive layer 11 in such a direction that the film 12 side faces the adhesive layer 11, and the film 12 is bonded to the adhesive layer 11 on the base material 5 by pressing the transfer foil from the surface opposite to the surface on the adhesive layer 11 side.
Thereafter, the transfer foil film is peeled off, whereby the film 12 is left on the base material 5 side in the shape of the adhesive layer 11, and the film 12 of the transfer foil except for the portion where the adhesive layer 11 is formed is peeled off from the adhesive layer 11. Thus, the film 12 adhered to the surface 6 of the base material 5 by the adhesive layer 11 remains on the base material 5 in the shape of the adhesive layer 11 printed by the ink jet printer 100, and the film 12 is formed on the surface 6 of the base material 5 in the shape of the image shown by the image layer 10. The image layer 10, which is composed of the adhesive layer 11 and the film 12, thus forms a desired image shape on the surface 6 of the substrate 5.
Next, on the surface of the image layer 10, the transparent layer 15 is formed by using the ink jet printer 100 as in the case of printing the adhesive layer 11. That is, an adhesive layer ink used as an adhesive constituting the transparent layer 15 is printed on the surface of the image layer 10 using the inkjet printer 100 in a shape capable of forming many slits 22 in a desired form on the slit layer 20. Thereby, the transparent layer 15 is formed on the surface of the image layer 10 opposite to the surface on the substrate 5 side.
At this time, the transparent layer 15 plays a role of leaving a distance between the image layer 10 and the slit layer 20, and thus is made thicker than the adhesive layer 11. For example, the adhesive layer 11 having a function of adhering only the film 12 to the substrate 5 is formed by printing only one layer of adhesive layer ink by the ink jet printer 100, and the transparent layer 15 is formed by printing three layers of adhesive layer ink. Thus, the plurality of transparent layers 15 are stacked, and the thickness of the transparent layers 15 is made larger than the thickness of the adhesive layer 11.
In this case, of the transparent layers 15 stacked in plural, the layer on the image layer 10 side is permanently cured immediately after the ink of the adhesive layer is applied. In addition, the layer on the slit layer 20 side is temporarily cured immediately after the ink of the adhesive layer is applied. The slit layer 20 is laminated in a state where, of the plurality of transparent layers 15 laminated, the layer located on the slit layer 20 side in this way is temporarily cured. For example, the slit layer 20 is laminated on the transparent layer 15 in a state where the 1 st layer and the 2 nd layer from the image layer 10 side among the three transparent layers 15 are permanently cured immediately after the ink of the adhesive layer and the 3 rd layer is temporarily cured immediately after the ink of the adhesive layer.
Next, the film 21 on which the slit layer 20 is formed is bonded to the transparent layer 15 by the same transfer film as the film 12 of the image layer 10. Specifically, the transfer foil is bonded to the transparent layer 15 in such a direction that the film 21 side faces the transparent layer 15, and the film 21 is bonded to the transparent layer 15 by pressing the transfer foil from the surface opposite to the surface on the transparent layer 15 side.
Thereafter, the film 21 is left on the transparent layer 15 side in the shape of the transparent layer 15 by peeling off the film of the transfer foil, and the film 21 and the film except for the portion of the transfer foil where the transparent layer 15 is formed are peeled off from the transparent layer 15. Thus, on the image layer 10, the film 21 adhered to the transparent layer 15 by the adhesive constituting the transparent layer 15 remains in the shape of the transparent layer 15 printed by the ink jet printer 100, and the film 21 is formed on the image layer 10 in a shape capable of forming many slits 22. Thus, the slit layer 20 is formed in the image layer 10 in a shape in which the vertical slit forming portions 26 and the horizontal slit forming portions 27 are formed in a checkered pattern by the plurality of vertical slits 23 and the horizontal slits 24. Finally, the adhesive layer 11 of the image layer 10 in the temporarily cured state and the slit layer 20 on the transparent layer 15 are permanently cured by irradiation with ultraviolet rays.
In the decorative structure of the present embodiment, the adhesive layer 11 and the transparent layer 15 are printed by the ink jet printer 100, and the film 12 of the image layer 10 and the film 21 of the slit layer 20 are bonded to the adhesive layer 11 and the transparent layer 15 by the transfer foil, whereby the image layer 10, the transparent layer 15, and the slit layer 20 are laminated on the surface 6 of the substrate 5.
Next, the operation of the decorative structure of the present embodiment will be described. When the image represented on the image layer 10 of the decorative body 1 is visually confirmed, the person who visually observes the image layer 10 visually confirms through the slit layer 20 located in front of the image layer 10. Therefore, when the image layer 10 is visually recognized, of the light reflected by the image layer 10 by the incident light from the outside, the light that has passed through the slits 22 of the slit layer 20 and reached the eyes of the viewer can be visually recognized by the viewer, and the light that has not passed through the slits 22 but is blocked by the thin film 21 of the slit layer 20 cannot be visually recognized by the viewer.
On the other hand, since the longitudinal slits 23 and the lateral slits 24 are formed in the slit layer 20, whether or not the light reflected by the image layer 10 passes through the slits 22 differs depending on the angle of the garnish 1 to the viewer. Further, since the vertical slit forming portions 26 and the horizontal slit forming portions 27 are formed in the slit layer 20, the method of passing the slits 22 of the light reflected by the image layer 10 differs depending on the position of the image layer 10.
First, a case where the garnish 1 is viewed from a direction perpendicular to the surface 6 of the base material 5 will be described. Fig. 6 is a detailed view of the portion D of fig. 2, and is an explanatory view of the garnish body when viewed from the vertical direction. When the garnish 1 is viewed from the vertical direction, light reflected in the vertical direction with respect to the surface 6 of the base material 5 among light reflected by the image layer 10 can be seen. Since the light reflected by the image layer 10 is directed toward the slit layer 20 after passing through the transparent layer 15, the light is also incident in the vertical direction from the transparent layer 15 side with respect to the slit layer 20.
Since many slits 22 formed in the slit layer 20 communicate in the thickness direction of the thin film 21 constituting the slit layer 20, most of light incident in the perpendicular direction with respect to the slit layer 20 passes through the slits 22. Therefore, when the garnish 1 is viewed from the vertical direction, the image layer 10 can be visually recognized in a shape substantially intact as the shape formed by the image layer 10 (see fig. 1).
On the other hand, when the garnish 1 is viewed from a direction inclined with respect to the surface 6 of the base material 5, the visibility differs depending on the direction of viewing. That is, since the slits 22 formed in the slit layer 20 have the longitudinal slits 23 and the lateral slits 24, when the oblique direction of the decorative body 1 is viewed in the direction in which the slits 22 are formed in the direction in which the film 21 is formed, an image is easily visible, and when the oblique direction of the decorative body 1 is viewed in a direction other than the direction in which the slits 22 are formed, an image is hardly visible.
Next, a case where the garnish 1 is viewed from a direction inclined with respect to the surface 6 of the base material 5 will be described. Fig. 7 is a detailed view of the portion D of fig. 2, and is an explanatory view of the garnish body when viewed from an oblique direction. When the garnish 1 is viewed from an oblique direction, of the light reflected by the image layer 10, light reflected in the oblique direction with respect to the surface 6 of the base material 5 can be seen, and light incident in the oblique direction from the transparent layer 15 side with respect to the slit layer 20 can be seen. On the other hand, since the slit layer 20 has many slits 22 including the vertical slits 23 and the horizontal slits 24, the direction of light incident from the transparent layer 15 side and the direction of formation of the slits 22 are different from each other in whether or not the light passes through the slits 22.
For example, the case where the direction in which the decorative body 1 is observed to be inclined is the direction in which the longitudinal slits 23 are formed in the direction in which the film 21 is formed is described, and in the case where light obliquely incident on the slit layer 20 from the transparent layer 15 side enters the longitudinal slits 23, the light can travel in the thickness direction of the slit layer 20 and can travel in the longitudinal direction of the longitudinal slits 23. This allows the light to pass through the longitudinal slit 23, and a person observing the garnish 1 can visually recognize the light.
On the other hand, when the light enters the lateral slit 24, the light contacts the inner wall of the lateral slit 24 and is blocked by the inner wall while proceeding in the thickness direction of the slit layer 20. This light is not blocked by the film 21 through the transverse slit 24, and the person who observes the garnish 1 cannot visually recognize the light. Accordingly, when the garnish 1 is viewed from a direction oblique to the direction in which the longitudinal slits 23 are formed, only the image layer 10 in the portion where the longitudinal slits 23 are located can be seen.
Fig. 8 is an explanatory view of the decorative body viewed from a direction oblique to the direction in which the longitudinal slits are formed. The vertical slits 23 and the horizontal slits 24 are arranged in parallel to form vertical slit forming portions 26 and horizontal slit forming portions 27. Therefore, when the garnish 1 is viewed from a direction oblique to the direction in which the vertical slits 23 are formed, the image layer 10 can be seen through all the vertical slit forming portions 26, and the image layer 10 cannot be seen through all the horizontal slit forming portions 27.
Therefore, in this case, as shown in fig. 8, the image displayed on the image layer 10 is not visible in the portion of the horizontal slit forming portion 27 out of the vertical slit forming portion 26 and the horizontal slit forming portion 27 formed in a checkered pattern.
Fig. 9 is an explanatory view of the garnish body when viewed from a direction oblique to the direction in which the lateral slits are formed. On the other hand, when the garnish 1 is viewed from the oblique direction along the forming direction of the lateral slits 24, of the light obliquely incident on the slit layer 20 from the transparent layer 15 side, the light entering the lateral slits 24 can pass through the lateral slits 24, but the light entering the longitudinal slits 23 cannot pass through the longitudinal slits 23. Therefore, when the garnish 1 is viewed from a direction oblique to the direction in which the lateral slits 24 are formed, only the image layer 10 in the portion where the lateral slits 24 are located can be seen.
Therefore, when the garnish 1 is viewed from the oblique direction along the forming direction of the lateral slits 24, the image layer 10 can be seen through all the lateral slit forming portions 27, and the image layer 10 cannot be seen through all the longitudinal slit forming portions 26. Therefore, in this case, as shown in fig. 9, the image displayed on the image layer 10 is not visible in the vertical slit forming portions 26 out of the vertical slit forming portions 26 and the horizontal slit forming portions 27 formed in a checkered pattern.
When the decorative body 1 decorated with the decorative structure of the present embodiment is visually confirmed, since the angle at which the decorative body 1 is observed is changed, these change continuously, the visibility of the image displayed on the image layer 10 changes continuously for each position on the decorative body 1.
In the decorative structure of the above embodiment, the slit layer 20 having the many slits 22 formed therein is disposed on the front surface side of the image layer 10 via the transparent layer 15, and therefore, when the decorative body 1 is observed, whether or not the light passing through the slits 22 can be visually confirmed can be changed depending on the angle of observation. Thus, the visibility of the image layer 10 can be changed by the angle at which the image layer 10 is viewed, simply by disposing the slit layer 20 on the front side of the image layer 10, without considering the relative position between the image layer 10 and the slit layer 20. As a result, the visual effect can be easily obtained.
Further, since the slit layer 20 has the vertical slit forming portions 26 and the horizontal slit forming portions 27, and a plurality of directions in which the slits 22 are arranged in parallel are formed, it is possible to variously change the visibility of the image layer 10 depending on the angle at which the image layer 10 is observed. As a result, a greater visual effect can be easily obtained.
Further, since the transparent layer 15 is formed of an adhesive and the slit layer 20 is bonded to the image layer 10 by the adhesive forming the transparent layer 15, the slit layer 20 and the transparent layer 15 can be easily laminated on the image layer 10. As a result, the visual effect can be obtained easily and at low cost.
Further, since the image layer 10 is formed by bonding the film 12 to the surface 6 of the base material 5 with an adhesive, the image layer 10 can be easily formed. As a result, the visual effect can be obtained easily and at low cost.
Further, by laminating a plurality of transparent layers 15, the slit layer 20 can be separated from the image layer 10, and a printed product having an excellent visual effect, that is, a lattice effect, can be obtained by forming a large number of slits 22 in a lattice shape.
Further, the thickness of the layer on the image layer 10 side among the plurality of transparent layers 15 stacked is obtained by permanent curing, and the film 21 is bonded in a temporarily cured state to smooth the surface of the layer on the slit layer 20 side, whereby the metallic luster of the film 21 (aluminum deposited film) can be improved. In addition, the adhesive layer 11 of the image layer 10 can also make the film 12 (aluminum deposited film) of the image layer 10 good by adhering the film 12 in a temporarily cured state.
[ modified example ]
In the decorative structure, the surface treatment is not particularly performed on the front surface side of the slit layer 20, but may be performed. For example, a transparent coating layer (クリアコート) serving as a protective layer may be applied by printing transparent ink or the like on the surface side of the slit layer 20. By applying such a protective layer, the slit layer 20 can be protected, and the visual effect can be continued for a long time.
In the above decorative structure, the image layer 10 is formed by bonding the film 12 to the base material 5 with the adhesive layer 11, but the image layer 10 may be formed by other methods. For example, the image layer 10 may also be formed by printing with ink on the surface 6 of the substrate 5 using an inkjet printer 100. The slit layer 20 may be formed by a method other than the film 21, or the slit layer 20 may be formed by printing with ink on the surface 6 of the transparent layer 15 using the inkjet printer 100.
In this way, by forming the image layer 10 and the slit layer 20 by printing with ink, all the layers can be formed by printing, and therefore, the decorative structure having the transparent layer 15 and the slit layer 20 can be more easily realized.
In the decorative structure, the slits 22 of the slit layer 20 are only the vertical slits 23 and the horizontal slits 24, but the types of the slits 22 may be three or more. By increasing the kinds of the slits 22 formed in different directions, more various visual effects can be obtained.
The transparent layer 15 may be formed using an adhesive other than an adhesive such as an adhesive layer ink. For example, the transparent layer 15 may be formed using hard ink other than adhesive layer ink. In this case, it is preferable to secure the degree of bonding between the image layer 10 and the transparent layer 15 and between the transparent layer 15 and the slit layer 20 by interposing an adhesive therebetween.
In addition, the decorative structure may be combined with the structures and the like used in the above embodiments and modifications as appropriate, or may be a structure other than the above structures. Regardless of the structure of the decorative structure or the like, by disposing the slit layer 20 having the many slits 22 formed therein on the front surface side of the image layer 10, the visibility of the image layer 10 can be changed depending on the angle at which the image layer 10 is observed, and a visual effect can be easily obtained.
