DETAILED DESCRIPTION OF THE INVENTION
An explanation will be given of an embodiment of a laminate capable of authenticating authenticity according to the present invention with reference to the drawings. The feature of the laminate for authenticity determination of the present invention is that a sheet-like substrate such as paper having fine perforations is laminated on both sides of a transparent sheet-like substrate, and the laminate is laminated on both sides of the transparent sheet. Since the perforations of the material are laminated at the same position or slightly shifted, only specific perforations can be observed from a specific observation direction.
[0034]
1 to 17 show the basic principle of the present invention. FIG. 1 shows a diagram in which an image (2a) is formed by perforation (3a) on a substrate (1a) of the first layer. The perforations (3a) shown in FIG. 1 are two-dimensionally and vertically formed at equal pitches, but in the present invention, the perforations (3a) may be randomly formed to form an image (2a). FIG. 2 shows a second layer substrate (1b) which is an intermediate layer between a first layer substrate (1a) and a third layer substrate (1c) described later. The base material (1b) of the second layer needs to be a light-transmitting base material. FIG. 3 shows a view in which a latent image (2c) is formed by perforation (3c) on the base material (1c) of the third layer. As shown in FIG. 4, the base material (1a) of the first layer, the base material (1b) of the second layer, and the base material (1c) of the third layer are sequentially bonded using an adhesive ( 4) is formed and laminated to obtain a laminated body (5a) capable of authenticating authenticity. FIG. 5 shows an XX ′ cross-sectional view of the laminate (5a) capable of authenticity determination shown in FIG. As shown in FIG. 5, the perforations (3c) formed in the third layer substrate (1c) laminated on the lower part of the first layer substrate (1a) form the first layer substrate (1a). It is necessary to arrange so that a part or all of the perforations (3a) formed in FIG.
[0035]
FIG. 6 shows a view when the laminate (5a) capable of authenticity determination is observed with reflected light. As shown in FIG. 6, only the image (2a) provided on the base material (1a) of the first layer is visible, and the image (2a) provided on the base material (1a) of the first layer shown in FIG. Since the perforations (3c) forming the latent image (2c) provided on the base material (1c) of the third layer that overlaps the perforations (3a) forming the holes are formed by fine perforations, the image ( Since the reflected light of the latent image (2c) observed through the perforations (3a) that formed 2a) is very small, the observer can observe the surface of the first layer substrate (1a) and the perforations (3a). Since only the contrast difference is recognized, the latent image (2c) formed on the base material (1c) of the third layer cannot be visually recognized.
[0036]
FIG. 7 shows a view when the laminated body (5a) capable of authenticity determination is observed with transmitted light from the vertical direction. As shown in FIG. 7, the latent image (2c) provided on the third layer substrate (1c) is clearly visible in the image (2a) provided on the first layer substrate (1a). (In this case the number 1). This is because of the perforations (3a) in the image (2a) provided on the first layer substrate (1a) shown in FIG. 5 and the latent image (3a) provided on the third layer substrate (1c). Since the perforation (3c) in 2c) overlaps, the amount of transmitted light is strong from the region where the perforation (3a) and perforation (3c) overlap, and from the region where the perforation (3a) and perforation (3c) do not overlap Since the transmitted light amount is viewed weakly, the latent image (2c) can be visually recognized in the image (2a) as shown in FIG.
[0037]
The other example of this invention is shown. FIG. 8 shows a view in which an image (2a) is formed by perforation (3a) on the base material (1a) of the first layer. Although the perforations (3a) shown in FIG. 8 are two-dimensionally and vertically formed at equal pitches, the present invention may form the image (2a) by randomly forming the perforations (3a). FIG. 9 shows a second layer substrate (1b) which is an intermediate layer between a first layer substrate (1a) and a third layer substrate (1c) described later. The base material (1b) of the second layer needs to be a light-transmitting base material. FIG. 10 shows a view in which a latent image (2c) is formed by perforation (3c) on the base material (1c) of the third layer. As shown in FIG. 11, the base material (1a) of the first layer, the base material (1b) of the second layer, and the base material (1c) of the third layer are sequentially bonded using an adhesive ( 4) is formed and laminated to obtain a laminated body (5b) capable of authenticating authenticity. FIG. 12 shows an XX ′ cross-sectional view of the laminate (5b) capable of authenticating authenticity shown in FIG. As shown in FIG. 12, the perforations (3c) formed in the third layer base material (1c) laminated on the lower part of the first layer base material (1a) form the first layer base material (1a). ) Must be regularly arranged in the peripheral region of the perforations (3a) formed. In this case, the perforations (3c) formed in the base material (1c) of the third layer are regularly arranged on the left side with respect to the perforations (3a) formed in the base material (1a) of the first layer. Although it is arranged, it may be arranged regularly in the right part, the upper part or the lower part, that is, in the peripheral region of the perforations (3a) formed in the base material (1a) of the first layer.
[0038]
FIG. 13 shows a view when the laminate (5b) capable of authenticating authenticity is observed with reflected light or when observed with transmitted light from the vertical direction. As shown in FIG. 13, only the image (2a) provided on the base material (1a) of the first layer is visible, and the latent image provided on the base material (1c) of the third layer shown in FIG. The perforations (3c) in which 2c) are formed are regularly arranged in the peripheral region of the perforations (3a) in which the image (2a) provided in the base material (1a) of the first layer is formed. Or, even when observed with transmitted light from the vertical direction, it cannot be visually recognized, and the observer recognizes only the contrast difference between the surface of the base material (1a) of the first layer and the perforations (3a). The latent image (2c) formed on the base material (1c) of the third layer cannot be visually recognized.
[0039]
FIG. 14 shows a view when the laminated body (5b) capable of authenticating authenticity is observed with transmitted light tilted in the X direction shown in FIG. As shown in FIG. 14, the latent image (2c) provided on the third layer substrate (1c) is clearly visible in the image (2a) provided on the first layer substrate (1a). (In this case the number 2). This is because the perforation (3c) in the latent image (2c) provided on the third layer substrate (1c) shown in FIG. 12 is formed on the first layer substrate (1a) ( Since it is regularly arranged in the peripheral region of the perforation (3a) in 2a), it is visually recognized that the perforation (3a) and the perforation (3c) are overlapped by tilting in the X direction and observing with transmitted light. From the region where the transmitted light amount is strong and the transmitted light amount is weak from the region where the perforations (3a) and the perforations (3c) do not overlap, the image (( The latent image (2c) can be visually recognized within 2a).
[0040]
As to the observable direction, as shown in FIG. 15, the perforations in which the latent image (2c) of the third layer base material (1c) laminated on the lower part of the first layer base material (1a) was formed. It depends on the arrangement rule between (3c) and the perforations (3a) in which the image (2a) of the substrate (1a) of the first layer is formed. That is, as shown in the XX ′ cross-sectional view of FIG. 15, the third layer base material (3a) is formed on the perforation (3a) in which the image (2a) provided on the first layer base material (1a) is formed. When the perforations (3c) forming the third image (2c) of 1c) are regularly arranged in Y1, it is necessary to incline in the X1 direction and observe with transmitted light, and regularly in Y2 When arranged, it is necessary to incline in the X2 direction and observe with transmitted light.
[0041]
Next, a case where different images can be seen by tilting from four different directions with transmitted light is shown. As the base material of the first layer, a base material in which the image shown in FIG. 1 or FIG. 8 is formed by perforation is used, and the base material of the second layer is the same as the base material shown in FIG. 2 or FIG. Use things. It is necessary to provide regularity to the perforations formed in the base material of the third layer so that different images can be viewed by tilting from four different directions with transmitted light. For example, as shown in FIG. 16, when it is desired to make four latent image images, ie, latent image (2c1), latent image (2c2), latent image (2c3), and latent image (2c4) appear. It is necessary to combine the four images to form a latent image (2c) on the third layer substrate as shown in FIG. 17, and the latent image (2c) provided on the third layer substrate. The perforations (3c) formed with the holes need to be regularly arranged in the peripheral region of the perforations (3a) formed with the image of the substrate of the first layer. When regularly arranged in Y1, it is necessary to incline in the X1 direction and observe with transmitted light, and when arranged regularly in Y2, incline in the X2 direction and observe with transmitted light. If it is regularly arranged in Y3, it is necessary to tilt it in the X3 direction and observe it with transmitted light. If it is regularly arranged in Y4, it is tilted in the X4 direction and transmitted light. It is necessary to observe.
[0042]
Therefore, the authenticity-determined laminate (5c) in which the latent image (2c) is provided on the third layer base material is tilted in the X1 direction and transmitted as shown in FIG. 18 (a). When observing with light, the latent image (2c1) (2 in this case) regularly arranged at Y1 is visually recognized, and as shown in FIG. 18B, the image is observed with transmitted light tilted in the X2 direction. In this case, the latent image (2c2) (in this case, 3) regularly arranged in Y2 is visually recognized, and as shown in FIG. 18 (c), Y3 is used when observing with transmitted light tilted in the X3 direction. Regularly arranged latent image (2c3) (4 in this case) is visually recognized, and as shown in FIG. 18 (d), when it is tilted in the X4 direction and observed with transmitted light, it is regularly arranged in Y4. The latent image (2c4) (5 in this case) is visually recognized. That is, four different images can be visually recognized by tilting from four different directions with transmitted light.
[0043]
In the laminate (5c) capable of determining authenticity, four images appear. Needless to say, two or three images can appear. The four images of the latent image (2c1), the latent image (2c2), the latent image (2c3), and the latent image (2c4) are regularly arranged vertically and horizontally with respect to the perforation (3a). However, they may be regularly arranged in an oblique direction. In this case, eight images may appear by combining the perforations regularly arranged in the upper, lower, left and right directions and the oblique perforations. Possible. In addition, by using such a plurality of latent image images, a part of each latent image image is differentiated in a moving image, and a layered product capable of determining authenticity is produced, and thus authenticity determination is performed by tilting with transmitted light. By observing the possible laminate by rotating it, the latent image can be observed as if it were moving. The four images of the latent image (2c1), the latent image (2c2), the latent image (2c3), and the latent image (2c4) are all different images, but the same image is used. Either the same image or different images may be combined.
[0044]
Next, a case where observation is performed with transmitted light from the vertical direction and a case where different images can be visually recognized by tilting from four different directions with transmitted light will be described. As the base material of the first layer, a base material in which the image shown in FIG. 1 or FIG. 8 is formed by perforation is used, and the base material of the second layer is the same as the base material shown in FIG. 2 or FIG. Use things. It is necessary to provide regularity to the perforations formed in the base material of the third layer in order to allow different images to be visually recognized when tilted from four different directions when transmitted light is observed from the vertical direction. For example, as shown in FIG. 19, five latent image images of a latent image (2c1), a latent image (2c2), a latent image (2c3), a latent image (2c4), and a latent image (2c5) are obtained. When it is desired to appear, it is necessary to combine these five images to form a latent image (2c) on the third layer substrate as shown in FIG.

Therefore, the authenticity-determined laminate (5d) in which the latent image (2c) is provided on the base material of the third layer is inclined and transmitted in the X1 direction as shown in FIG. 21 (a). When observing with light, the latent image (2c1) (2 in this case) regularly arranged on Y1 is visually recognized, and as shown in FIG. 21B, the image is observed with transmitted light tilted in the X2 direction. In this case, the latent image (2c2) (in this case, 3) regularly arranged in Y2 is visually recognized, and as shown in FIG. 21 (c), Y3 is used when observing with transmitted light tilted in the X3 direction. Regularly arranged latent image (2c3) (4 in this case) is visually recognized, and as shown in FIG. 21 (d), when it is tilted in the X4 direction and observed with transmitted light, it is regularly arranged in Y4. The latent image (2c4) (5 in this case) is visually recognized, and as shown in FIG. Regularly arranged latent image Y5 when observed (2C5) with light (in this case 1) is viewed. That is, when viewing with transmitted light from the vertical direction, and five different images tilted from four different directions with transmitted light can be visually recognized.
[0046]
In the laminate (5d) capable of determining authenticity, five images appear. Needless to say, two, three, and four images can also appear. Also, the five images of the latent image (2c1), the latent image (2c2), the latent image (2c3), the latent image (2c4), and the latent image (2c5) are above and below the perforation (3a). Although it is regularly arranged in the center of the left and right, it may be regularly arranged in an oblique direction. In this case, the perforations arranged regularly in the top, bottom, left, and right and the perforations that are regularly arranged obliquely are combined. Nine images can also appear. The five images of the latent image (2c1), the latent image (2c2), the latent image (2c3), the latent image (2c4), and the latent image (2c5) are all different images. However, the same image may be used, or different images may be combined with the same image.
[0047]
As described above, when the stacks (5a) and (5d) capable of authenticating authenticity are put together, the latent image provided on the base material of the third layer is constituted by the perforations obtained by combining n different latent images. The perforations for forming the n1 latent image formed on the third layer base material are arranged so as to partially or entirely overlap the perforations for forming the image provided on the first layer base material. The perforations forming the n2 latent image formed on the base material of the third layer are arranged so as not to overlap the perforations forming the image provided on the base material of the first layer, and the perforations forming the image N3, n4, n5 provided on the third layer base material with regularity in the peripheral region, and the perforations forming the latent image form the perforations forming the image provided on the first layer base material The image is formed in a region other than the region where n-1 latent image images are provided on the base material of the third layer without overlapping. Are arranged with regularity in the peripheral region of the perforation formed by it is necessary to laminate.
[0048]
As described above, when the laminates (5b) and (5c) capable of authenticating authenticity are put together, the latent image provided on the base material of the third layer is constituted by the perforations synthesized by n different latent image images, The perforation for forming the n1 latent image formed on the third layer base material does not overlap with the perforation for forming the image formed on the first layer base material. N2, n3, n4... Perforations forming a latent image formed on the third layer base material, and perforations forming an image provided on the first layer base material. Without overlapping, it is necessary to arrange and laminate with regularity in the peripheral region of the perforations forming the image, other than the region where the n−1 latent image images provided on the base material of the third layer are provided.
[0049]
Next, a case where an image can be visually recognized three-dimensionally when observed with transmitted light from the vertical direction will be described. As the base material of the first layer, a base material in which the image shown in FIG. 1 or FIG. 8 is formed by perforation is used, and the base material of the second layer is the same as the base material shown in FIG. 2 or FIG. Use things. It is necessary to provide regularity to the perforations formed in the base material of the third layer so that an image can be viewed stereoscopically when observed with transmitted light from the vertical direction. As shown in FIG. 22, the perforations (3c) for forming the latent image (2c) formed on the third layer substrate are regular in the peripheral region of the perforations (2a) provided on the first layer substrate. Must be provided symmetrically such as left and right and up and down. In FIG. 22, the peripheral region of the perforation (2a) provided in the base material of the first layer is provided symmetrically with regularity. Even with the configuration as in the fifth embodiment, the effect of the present invention can be obtained.
[0050]
Perforations (3c) provided regularly and symmetrically in the right and left sides in the peripheral region of the perforations (3a) provided with the latent image (2c) on the base material of the first layer are formed on the base material of the third layer. As shown in FIG. 23, when the manufactured laminate (5e) capable of determining authenticity is observed with transmitted light from the vertical direction, the human left eye can see the right perforation (3c1), and the human right eye The left perforation (3c2) is visible. That is, the perforations (3c1) and the perforations (3c2) need to be arranged at positions where the perforations (3a) serve as a parallax barrier. Therefore, the latent image (2c) formed on the base material of the third layer is visually recognized in three dimensions, that is, with a sense of depth.
[0051]
Next, a case where an image continuously moves and can be visually recognized when tilted continuously from the vertical direction and observed with transmitted light, or a case where a different latent image can be visually recognized will be described. As the base material of the first layer, a base material in which the image shown in FIG. 1 or FIG. 8 is formed by perforation is used, and the base material of the second layer is the same as the base material shown in FIG. 2 or FIG. Use things. When perforated to be formed on the third layer base material so that the image continuously moves when viewed with transmitted light tilted continuously from the vertical direction, or a different latent image can be viewed. It is necessary to have regularity. For example, as shown in FIG. 24, when the latent image (2c1), the latent image (2c2), the latent image (2c3), and the latent image (2c4) are to be continuously displayed, These five images need to be combined to form a latent image (2c) on the third layer substrate as shown in FIG.
[0052]
When combining the latent image (2c1), the latent image (2c2), the latent image (2c3), and the latent image (2c4), in order to prevent the transmitted image from being visually recognized from the vertical direction. As shown in FIG. 26 (a), they are arranged so as not to overlap with the perforations formed in the base material of the first layer. Next, a perforation (3c1) for forming a latent image (2c1) is formed adjacent to the perforation (3a1). Next, a perforation (3c2) for forming a latent image (2c2) is formed adjacent to the perforation (3c1). Next, a perforation (3c3) for forming a latent image (2c3) is formed adjacent to the perforation (3c2). Next, a perforation (3c4) for forming a latent image (2c4) is formed adjacent to the perforation (3c3). The latent image (2c1), the latent image (2c2), the latent image (2c3), and the latent image (2c4) are combined to form a latent image (2c) on the third layer substrate. The perforations to be formed must be formed between the perforations (3a1) to the perforations (3a2) formed in the first layer substrate, that is, between the regions (S) as shown in FIGS. is there.
[0053]
In such a case, the latent image formed on the third layer base material is a latent image formed on the third layer base material by perforation obtained by combining n different latent image images. The perforations that form the latent image of n1 are regularly arranged in the peripheral region of the perforations that form the image without overlapping the perforations that form the image provided on the substrate of the first layer. The perforations forming the n2, n3,... Latent image formed on the base material of the first layer form the n1 latent image without overlapping the perforations forming the image provided on the first base material. It is necessary to sequentially arrange the perforations that form n2, n3,... Latent image with regularity in the same direction as the perforation positions to be performed and at positions separated by different distances.
[0054]
As shown in FIG. 26 (a), the latent image (2c) is regularly arranged on the third layer substrate shown in FIG. 25 with respect to the perforations (3a) forming the first layer substrate. When the laminated body (5f) capable of authenticating authenticity is continuously tilted from the vertical direction and observed with transmitted light, the latent image cannot be observed with the transmitted light from the vertical direction as shown in FIG. However, as the degree of tilting with the transmitted light increases, the latent image (2c1), the latent image (2c2), the latent image (2c3), and the latent image (2c4) provided on the base material of the third layer are sequentially arranged. The latent image (2c) can be visually recognized by moving continuously. When the latent image (2c1), the latent image (2c2), the latent image (2c3), and the latent image (2c4) are images of different designs, the images are observed with transmitted light inclined continuously from the vertical direction. In some cases, latent image images with different designs can be seen.
[0055]
Next, a case where an image can be visually recognized by moving continuously when viewed with transmitted light from the vertical direction, or when tilted continuously from the vertical direction and observed with transmitted light, or a case where a different latent image can be visually recognized is shown. . As the base material of the first layer, a base material in which the image shown in FIG. 1 or FIG. 8 is formed by perforation is used, and the base material of the second layer is the same as the base material shown in FIG. 2 or FIG. Use things. In order to make it possible to visually observe moving images when viewing with transmitted light from the vertical direction or when tilting continuously from the vertical direction and viewing with transmitted light, or to allow different latent image images to be viewed. It is necessary to provide regularity to the perforations formed in the base material of the three layers. For example, as shown in FIG. 28, the latent image (2c1), the latent image (2c2), the latent image (2c3), the latent image (2c4), and the latent image (2c5) are continuously displayed. When these images are desired to appear, it is necessary to combine these five images to form a latent image (2c) on the third layer substrate as shown in FIG.
[0056]
When the latent image (2c1), the latent image (2c2), the latent image (2c3), the latent image (2c4), and the latent image (2c5) are combined, as shown in FIG. 30 (a). In the case of a latent image (2c1) that is observed with transmitted light in the vertical direction, the perforations (3c1) are arranged so that part or all of the perforations (3c1) overlap with the perforations formed in the base material of the first layer. . Next, in order to prevent the transmitted image from being visually recognized from the vertical direction, as shown in FIG. 30A, it is arranged so as not to overlap the perforations formed in the base material of the first layer. Next, a perforation (3c2) for forming a latent image (2c2) is formed adjacent to the perforation (3a1). Next, a perforation (3c3) for forming a latent image (2c3) is formed adjacent to the perforation (3c2). Next, a perforation (3c4) for forming a latent image (2c4) is formed adjacent to the perforation (3c3). Next, a perforation (3c5) for forming a latent image (2c5) is formed adjacent to the perforation (3c4). In this case, four images of the latent image (2c2), the latent image (2c3), the latent image (2c4), and the latent image (2c5) are obtained from the perforations (3a1) formed on the base material of the first layer. It is necessary to form between the perforations (3a2), that is, between the regions (S) as shown in FIGS. 30 (a, b).
[0057]
In such a case, the latent image formed on the third layer base material is a latent image formed on the third layer base material by perforation obtained by combining n different latent image images. The peripheral region of the perforations forming the image has regularity so that the perforations that form the n1 latent image image partially or entirely overlap with the perforations that form the image provided on the substrate of the first layer. An image is formed such that the perforations that are arranged and form the n2 latent image provided on the third layer substrate do not overlap the perforations that form the image provided on the first layer substrate. The perforations that are arranged regularly in the peripheral area of the perforations and that form n3, n4... Latent image formed on the third layer base material are formed on the perforations that form the image provided on the first layer base material. In the same direction and different distance from the punching position for forming the n2 latent image without overlapping It is necessary only to form the n3, n4 ... latent images with regularity to a remote location perforations are sequentially arranged.
[0058]
With respect to the perforations that form the latent image (2c) on the first layer substrate shown in FIG. 29, the layers are regularly arranged and stacked as shown in FIG. Further, when the laminate (5g) capable of determining authenticity is continuously tilted from the vertical direction and observed with transmitted light, a latent image (2c1) is observed with transmitted light from the vertical direction as shown in FIG. The latent image (2c2), the latent image (2c3), the latent image (2c4), and the latent image (2c5) are recognized in this order as the degree of tilting with transmitted light increases, and the latent image provided on the third layer substrate is The image (2c) can be visually recognized by moving continuously. When the latent image (2c1), the latent image (2c2), the latent image (2c3), the latent image (2c4), and the latent image (2c5) are images of different designs, they are continuously from the vertical direction. When tilted and observed with transmitted light, latent image images with different designs can be seen.
[0059]
The perforation of the present invention can be applied with a laser perforation apparatus or the like, and the size is preferably 50 μm to 1000 μm. The size of the perforations is related to the thickness of the laminate and the resolution and number of images to be expressed. Naturally, when a high-resolution image is expressed in a specific area, a hole having a diameter as small as possible is necessary. However, if it is several tens of microns or less, it is difficult to create the hole. In addition, when a large-diameter perforation is used, an image that can be expressed becomes rough.
[0060]
The base material of the first layer and the base material of the third layer used in the present invention are not particularly limited, and paper sheets, films, plastics, metals and the like can be used. Further, the thicknesses of the base material of the first layer and the base material of the third layer are not particularly limited, but are preferably about 0.1 mm to 1.0 mm.
[0061]
The light-transmitting second layer base material used in the present invention may be any plastic or laminate film that can transmit light. When a base material that does not transmit light is used, it is perpendicular to the transmitted light. When observed from the direction or when tilted with transmitted light, the latent image provided on the third layer cannot be viewed, and the effects of the present invention cannot be achieved. The thickness of the base material of the second layer is not particularly limited, but is preferably about 0.1 mm to 5.0 mm.
[0062]
For example, the thicknesses of the first layer base material, the second layer base material, and the third layer base material are d, and the perforations provided in the first layer base material and the third layer base material In order to make the diameter of each of the base materials d as similar to the thickness of each base material and to allow observation at an angle θ from the vertical direction of the base material, the center of the perforation provided in the base material of the third layer and the first It is necessary to set the distance from the position of the third layer corresponding to the center of the perforations provided on the base material of this layer to 2 d · tan θ. However, in this case, the effect of the present invention cannot be obtained when the observation angle is ± 45 ° or more (FIG. 44).
[0063]
The shape of the perforation of the present invention is not particularly limited, and it is necessary to form at least one of a circular shape, a polygonal shape (triangle, quadrangle, etc.) and a specially shaped perforation. By using polygonal or specially shaped perforations, the anti-counterfeiting effect is improved because it becomes difficult to be duplicated.
[0064]
The latent image of the third layer of the present invention is composed of at least one of letters, numbers, symbols, and patterns, so that it is true or false when observed from the vertical direction with transmitted light or when tilted with transmitted light. The discrimination effect is improved.
[0065]
In addition, even when the size of the perforations forming the latent image on the substrate and the image of the present invention are the same, depending on the position of the perforations, the latent image having a gradation is visually recognized when the substrate is observed from an oblique direction. be able to.
[0066]
Further, in the present invention, in order to laminate the base material of the first layer, the base material of the second layer, and the base material of the third layer, the base material of the first layer and the base material of the second layer An adhesive layer may be provided therebetween, and an adhesive layer may be provided between the second layer substrate and the third layer substrate. Further, the intermediate layer of the base material of the second layer may be a multilayer of two or more layers. Further, the base material may be laminated on the back surface of the base material of the first layer and / or the base material of the third layer.
[0067]
The 2nd layer which consists of a base material which has the optical transparency of the present invention may be constituted by colorless, colored, and a plurality of colors. When colored and a plurality of colors are used, the latent image formed on the third layer can be visually recognized with color information. Further, the color can be made different for each latent image. In addition, when using a base material in which the second layer made of a light-transmitting base material emits light by ultraviolet rays, the laminate that can determine authenticity of the present invention is observed with transmitted light by irradiating the ultraviolet rays. The emitted latent image can be visually recognized. .
[0068]
In the third layer of the present invention, a single latent image is provided in a form that can be observed from the back side by providing perforations for camouflaging a latent image formed of perforations formed by perforations arranged two-dimensionally. In the case where a laminate capable of authenticating authenticity is produced, it is possible to prevent the latent image from being visually recognized from the back surface. In this case, the individual perforation positions of the perforation group that forms the latent image in the third layer correspond to the individual perforation positions of the perforation group that forms the image in the first layer. It is necessary to provide a camouflage perforation in addition to the place where it is arranged. The camouflage perforation is shown in FIG.
[0069]
FIG. 45 shows the arrangement relationship between the first layer image and the third layer latent image in the above configuration in a simple manner conceptually.
[0070]
FIG. 46 shows a case where the perforations forming the image and latent image of the present invention are formed obliquely at a specific angle with respect to the substrate. FIG. 46 (a) shows the same configuration as that of the laminate (5a) capable of determining authenticity except for the perforation angle. FIG. 46B shows a configuration similar to that of the laminate (5b) capable of determining authenticity except for the perforation angle. FIG. 20D shows a configuration similar to that of the laminate (5c) capable of authenticating other than the perforation angle. FIG. 46 (d) shows a configuration similar to that of the laminate (5d) capable of authenticating other than the perforation angle. FIG. 46 (e) shows the same configuration as that of the laminate (5e) capable of determining authenticity except for the angle of perforation. FIG. 20 (f) shows a configuration similar to that of the laminate (5f) capable of authenticating other than the perforation angle. These effects are different from the stacks (5a, 5b, 5c, 5d, 5e, 5f) that can determine authenticity, but images cannot be observed when viewed with transmitted light from the vertical direction, but when tilted. An image is observed on the screen, and a latent image is observed when the image is further tilted. FIG. 47 shows a diagram in the case where the perforation of the present invention is formed so that the diameter of the perforation becomes smaller in the depth direction. FIG. 47 shows an example of a truncated cone.
