Description

The present invention relates to an anti-counterfeit medium having a window as a base material in the field of valuable printed matter such as banknotes, passports, securities, identification cards, and toll tickets that require an anti-counterfeiting effect.

Valuable printed matter such as banknotes, passports, securities, identification cards, and toll tickets are required not to be forged or tampered with due to their nature. Printing with target change ink is applied. Further, as an anti-counterfeiting technique for processing the paper base material itself, a draft, a thread, a mixed abstract of functional fibers and the like are used.

Further, as an anti-counterfeiting technique applied to the base material itself, a technique of providing a transparent window on the base material is used for banknotes of Australia, Canada and the like. In these banknotes, the transparent window configuration is such that the base material itself is composed of a transparent polymer material and the circumference of the window is shielded by printing, and its existence can be easily authenticated, so it is a true / false discrimination factor. It is used.

Further, as a technique of applying a transparent window to a base material, not only when the base material is a polymer material, an opening is provided in a part of the base material made of paper, and a film is provided so as to cover the opening. (For example, see Patent Document 1). The technique of Patent Document 1 is characterized by the shape of the film, and is, for example, a structure that can be palpated by the difference in surface properties between the film having a triangular protrusion or an arch shape and the paper base material. .. Further, the technique of Patent Document 1 describes that, as an additional element, the window area is printed or embossed, and this is used as a truth discrimination element.

Further, in order to form the surface of the base material on which the films constituting the window are laminated flat, a securities certificate in which the film is laminated in the recesses of the base material has been proposed (see, for example, Patent Document 2), and security is applied to the window. As an element, it is disclosed that a film is provided with a diffraction structure, a microprint, a thin film, or the like. Since the color and image of the diffraction structure change depending on the observation angle, authenticity determination can be easily performed.

However, in the technique of Patent Document 1, the region where the opening provided in the film and the base material overlaps is configured as a window, but the shape of the opening can be easily manufactured by punching or cutting. Therefore, there was a problem that it was forged when it was configured with only windows. Further, even if the window is embossed or printed, since the processing technology itself is a known technology, there is a risk of forgery, and it has been desired to prevent forgery of valuable printed matter provided with a window. ..

Further, even in the technique of Patent Document 2, there is a problem that if only the window is configured, the window is forged as in Patent Document 1, and the window has security elements such as a diffraction grating, a microprint, and a thin film. Although the anti-counterfeiting effect is improved to a certain extent, since these techniques are also known, it has been desired to prevent counterfeiting of valuable printed matter provided with a window.

Further, the shape of the window disclosed in the techniques of Patent Document 1 and Patent Document 2 (the technique used for the Euro ticket) is only a shape such as a circle or a quadrangle, and the shape of the window is simply based on the shape. It was restricted by the shape of the punched material.

The present invention is intended to solve the above-mentioned problems, and provides a highly authenticated window, which is an anti-counterfeit medium having a window on a base material and having an improved anti-counterfeiting effect on valuable printed matter. It is a thing. It also provides an anti-counterfeit medium with no restrictions on the shape of the window.

The anti-counterfeit medium of the present invention comprises a substrate having at least one opening, the opening of which is covered with a laminated film or filled with a transparent material to form a window, the opening of which is of the substrate. It is characterized by having a shape that surrounds a part of it.

Further, in the anti-counterfeit medium of the present invention, a contour portion having a contour element is formed along at least a part of the contour of the base material surrounded by the opening, and the contour element is composed of a printing material and surrounds the contour element. It is characterized by having either a structure having a thickness different from that of the base material or a structure made of a metal foil.

When the contour element is composed of a printing material, the contour element is i) formed by a printing material of a different color from the substrate surrounded by the opening, or ii) the substrate surrounded by the opening. It is characterized by being raised and formed by printing materials of the same color or different colors, or formed by iii) watermark ink.

The anti-counterfeit medium having a window of the present invention can be used for authenticity determination by authenticating the base material surrounded by the opening, and the base material surrounded by the opening has the effect of improving the authenticity of the window. Will be. Further, unlike the structure of a window formed by covering a region punched out of a base material of the prior art with a film, the base material surrounded by an opening is provided inside the window. Since it cannot be manufactured without a process not found in the prior art, it has an excellent anti-counterfeiting effect.

Further, the anti-counterfeit medium having a window of the present invention includes a base material surrounded by an opening, whereas the shape of the window of the prior art is limited to a simple shape such as a circle or a quadrangle. Since the shape of the window can be configured, the problem that the shape of the window is restricted can be solved.

Next, in the ultrasonic processing step (S2) shown in FIG. 12, the thermoplastic resin layer (13) was laminated between the horn (31) and the anvil (33) as shown in FIG. 13 (a). The base material (2) is arranged and ultrasonic processing is performed. In the ultrasonic processing step (S2), the mold (32) shown in FIG. 11 is used to perform ultrasonic processing on the base material (2) on which the thermoplastic resin layer (13) is laminated, but the mold (32) is used. ), That is, the height difference between the concave first region (32A) and the convex second region (32B) shown in FIG. 11B is the opening (11) in the base material (2). In order to provide the mold (32), a mold (32) having the same configuration as the sum of the thicknesses of the thermoplastic resin layer (13) and the base material (2) on the side with which the mold (32) comes into contact may be used. The height of the mold (32) may be larger than the sum of the thicknesses of the thermoplastic resin layer (13) and the base material (2) on the side with which the mold (32) contacts, but on the opposite side. In the thermoplastic resin layer (13), that is, in FIG. 13 (a), the pressure during ultrasonic processing described later is applied so that the thermoplastic resin layer (13) laminated on the upper side of the base material (2) does not penetrate. Need to be adjusted. Further, the height of the mold (32) may be smaller than the sum of the thicknesses of the thermoplastic resin layer (13) and the base material (2) on the side where the mold (32) comes into contact, but ultrasonic processing It is necessary to adjust the pressure during ultrasonic processing, which will be described later, in order to form the opening (11) and the window (10).

When ultrasonic processing is performed, as shown in FIG. 13 (b), the horn (31) descends, sandwiching the base material (2), and performing ultrasonic processing. When ultrasonic processing is performed, as shown in the enlarged view of FIG. 13 (b), the base material (2) corresponding to the convex second region (32B), more specifically, the convex second region. In the base material (2) on the thermoplastic resin layer (13) in contact with (32B), the base material (2) is originally brought into contact with the base material (2) by ultrasonic vibration from the horn (31) and pressurization due to descent. As shown in FIG. 13 (c), the constituent fibers are moved outward along the contour of the second region (32B), so that the opening (11) corresponding to the second region (32B) is accommodated. ) Is formed, and the thermoplastic resin layer (13) laminated on the front and back of the base material (2) in the region of the opening (11) is in a bonded state to form the window (10). Further, the base material (2) corresponding to the concave first region (32A), specifically, the base material on the thermoplastic resin layer (13) in contact with the concave first region (32A). In (2), since the ultrasonic processing is not performed, the state remains as it is, and as shown in FIG. 13 (c), the base material (2') surrounded by the opening (11) is formed. NS. The arrow line shown in FIG. 13 indicates the direction in which the fibers constituting the base material (2) are brought toward the contour of the opening (11).

As described above, the window (10) can be formed by setting the height of the mold (32) within a predetermined range, but in the ultrasonic processing step (S2), ultrasonic waves are required. Ultrasonic processing may be performed by adjusting the processing conditions of the processing machine (30). The specific processing conditions of the ultrasonic processing machine (30) are the amplitude, pressure, and processing time of the ultrasonic vibration, and the amplitude of the ultrasonic vibration is the swing width (longitudinal vibration) of the tip of the horn. Further, the pressure is the pressure at which the horn (31) and the mold (32) press the base material (2), and the ultrasonic vibration time is the time when the base material (2) is ultrasonically processed. It's time to do it.

According to the ultrasonic processing machine (W5080 stamp type manufactured by Nippon Avionics Co., Ltd.) used by the applicant, the amplitude can be adjusted in the range of 0.5 to 50 μm and the pressure is in the range of 0.001 MPa to 0.4 MPa. It can be adjusted with. The larger the value of these conditions, the easier it is for the fibers constituting the base material to move. Therefore, it may be adjusted as necessary. According to the ultrasonic processing machine (W5080 stamp type manufactured by Nippon Avionics Co., Ltd.), the time for performing ultrasonic processing can be adjusted, and may be adjusted as necessary. The range of adjustment described above is based on the ultrasonic processing machine (W5080 stamp type manufactured by Nippon Avionics Co., Ltd.), and the range of adjustment differs depending on the specifications of various ultrasonic processing machines. Since the principle of forming (10) is the same, processing may be performed by appropriately adjusting. By adjusting the processing conditions of these ultrasonic processing machines according to the conditions of the base material (2) and the thermoplastic resin layer (13), the fibers constituting the base material (2) can be separated into the second region (2). The opening (11) corresponding to the second region (32B) can be formed by moving outward along the contour of the 32B), and the front and back surfaces of the base material (2) can be formed in the region of the opening (11). The thermoplastic resin layer (13) laminated on the surface is in a bonded state, and the window (10) can be formed.

A feature of the configuration of the window (10) formed by ultrasonic processing is that the fibers are attracted to the outside along the contour of the convex second region (32B), so that the opening shown in FIG. 13 (c) is exhibited. A region (S) having a high fiber density is formed along the contour of (11), and when the opening (11) is formed by the above-mentioned laser processing, die cutting, or the like, the opening (11) is formed. Only the fibers existing in the above are punched out and removed, and the region (S) having a high density of fibers as shown in FIG. 13 (c) is not formed. Further, unlike the processing method of the present invention, it is possible to form a region having a high density by embossing the paper base material, but in this case, since the fibers do not move as in the present invention, the paper base material is used. The amount of fiber per unit area of is the same. On the other hand, in the region (S) where the fiber density is high when the window (10) of the present invention is formed by ultrasonic processing, the amount of fibers is higher than that of the surrounding base material (2) due to the movement of the fibers. , The fiber density is high. In the case of the pattern shown in FIG. 9, the contour of the opening (11) is an inner circumferential portion and an outer circumferential portion of the “doughnut shape”.

Further, the thickness (H) of the region (S) having a high fiber density shown in FIG. 13 (c) is the surrounding base material (2) according to one form of forming the window (10) by ultrasonic processing. ) Is formed in the same state as the thickness. As described above, unlike the processing method of the present invention, it is possible to form a region having a high fiber density by embossing the paper base material, but in this case, it is compressed in the thickness direction of the paper base material. The thickness is thinner than the surrounding area. On the other hand, in the configuration of the window (10) formed by the ultrasonic processing of the present invention, as shown in FIG. 13 (c), the fibers constituting the base material (2) are brought together to increase the density of the fibers. Another feature is that the thickness of the base material (2) does not decrease.

The effect of the anti-counterfeiting medium (1) provided with the window (10) formed by ultrasonic processing is that the region (S) where the fibers are gathered by ultrasonic processing is the surrounding region, that is, ultrasonic processing is applied. Since the fiber density is partially higher than that of the base material (2) which is not used, the color of the paper is visually recognized darker when observed under reflected light, and darker when observed under transmitted light. The authenticity of the window (10) can be enhanced. It is preferable to form the range (T) of the region (T) where the fibers are gathered by the ultrasonic processing shown in FIG. 13 (c) to be 100 μm or more, because the contour of the window (10) is improved in authenticity.

FIG. 14 is a diagram showing another configuration of the window (10) formed by ultrasonic processing, and is the thickness (H) of the region (S) where the fiber density is high with respect to the configuration shown in FIG. 13 (c). ) Is formed thicker than the thickness of the surrounding base material (2), and the thermoplastic resin layer (13) is also formed in a raised state according to the region (S) where the fiber density is high. As shown in FIG. 14, when the thermoplastic resin layer (13) is raised by the region (S) where the fiber density is high, the contour of the opening (11) is raised, so that the window is also three-dimensionally raised. It is preferable because the shape of (10) can be visually recognized. The thickness (H) of the region (S) having a high fiber density is preferably 20 μm or more with respect to the base material (2) in order to obtain a three-dimensional visual effect, and is 50 μm in consideration of distribution suitability. It is preferably as follows.

As shown in FIG. 13 (c), is the thickness (H) of the region (S) having a high fiber density formed in the same state as the thickness of the surrounding base material (2), or is shown in FIG. As shown, whether the thickness (H) of the region (S) having a high fiber density is formed in a state of being thicker than the thickness of the surrounding base material (2) is determined by the mold (32) by ultrasonic processing. The thermoplastic resin layer (2) on the side where the surface of the mold (32) (the convex surface of the second region (32B)) comes into contact with the mold (32) when the base material (2) is pressed. It depends on how far the 13) is pushed up, and as shown in FIG. 14, when the thermoplastic resin layer (13) on the side in contact with the mold (32) is pushed up to the surface of the base material (2), the density of the fibers The thickness (H) of the region (S) having a high value is formed to be thicker than the thickness of the surrounding base material (2). On the other hand, as shown in FIG. 13 (c), when the thermoplastic resin layer (13) on the side in contact with the mold (32) cannot be pushed up to the surface of the base material (2), the fiber density is high. The thickness (H) of the region (S) is formed in the same state as the thickness of the surrounding base material (2).

The effect of the method of producing the anti-counterfeit medium (1) provided with the window (10) formed by ultrasonic processing is that the above-mentioned base material (2) is punched out and the laminated film (12) is laminated or the transparent material (I). ) Is complicated in the manufacturing process including the arrangement of the base material (2') when the window (10) is formed, but when the window (10) is formed by ultrasonic processing, the window (10) is formed. It is an excellent advantage that the window (10) can be formed by one processing and can be manufactured without requiring the positional accuracy of the base material (2').

In the present invention, in the case of the configuration in which the laminated film (12) is laminated on the base material (2), a difference in unevenness occurs between the portion where the laminated film (12) is laminated and the base material (2) (FIG. 2A, FIG. In FIGS. 3 (a) and 9 (b), the surface of the laminated film (12) is the base material (2) as shown in FIG. 15 (a) in consideration of the laminated form and durability during distribution. It may have the same structure as the surface of the base material (b), or as shown in FIG. 15 (b), it may be laminated at a position lower than the surface of the base material (2). In this case, depending on the thickness of the laminated film (12), the laminated film (12) may be laminated after forming a recess in the base material (2) in advance. As a means for forming the concave portion, the above-mentioned laser processing or, in the case of a paper base material, the later-described excavation processing can be used.

(Second embodiment)

It is an anti-counterfeit medium (1) provided with a contour portion (20) on which a contour element (21) is formed for improving the visibility of the anti-counterfeit medium (1), and other configurations are the same as those of the first embodiment. .. Also in the second embodiment, the shape of the opening (11) is not particularly limited as described above, but as an example, the shape of the opening (11) is composed of a “doughnut shape” and is a base material. A configuration in which a part of (2) is surrounded by a "circle" will be described.

(Outline part)
FIG. 16 is a plan view of the anti-counterfeit medium (1) according to the second embodiment, and is an enlarged view showing a region in which the window (10) is formed. In the present invention, the contour portion (20) is formed along at least a part of the contour of the base material (2') surrounded by the opening (11), and the contour portion (20) has a contour element (21). Is formed. In FIG. 16, the contour element (21) composed of linear strokes is formed along the entire contour of the “circular shape” which is the shape of the base material (2') surrounded by the opening (11). It shows the formed state.

FIG. 17 is a diagram showing another configuration of the contour element (21) formed in the contour portion (20), and FIG. 17 (a) shows the contour element (21) composed of broken lines. 17 (b) is an example in which a contour element (21) composed of dotted lines is formed, and FIG. 17 (c) is an example in which a contour element (21) composed of dotted lines is formed. This is an example in which the contour element (21) is formed. As shown in FIGS. 17 (a) to 17 (c), if the contour portion (20) is formed along the contour of the window (10), the image constituting the contour portion (20) of the present invention. There is no limit to the line.

FIG. 18 is a diagram showing a configuration different from that of the contour portion (20) shown in FIG. 17, and is an enlarged view of a part of the contour portion (20). The contour portion (20) shown in FIG. 18 (a) is an example in which a plurality of point-shaped contour elements (21) are formed, and the contour portion (20) shown in FIG. This is an example in which a plurality of contour elements (21) are formed. Explaining this by replacing it with a printing technique, the contour element (21) shown in FIG. 16 is a state in which the base material (2) is completely filled with ink, that is, a so-called solid printing state, and is shown in FIG. 18 (a). ) And FIG. 18 (b) are configured to express the same pattern by arranging a plurality of fine halftone dots or image lines in the same area. Therefore, as shown in FIGS. 18A and 18B, even when the contour portion (20) is formed by the plurality of contour elements (21), it is the same as the contour portion (20) shown in FIG. As can be visually recognized, the configurations shown in FIGS. 18 (a) and 18 (b) may be formed as the contour portion (20).

In the second embodiment, there are three forms of the contour element (21), and detailed configurations of each will be described in order. The structure of the transparent material (I) filled in the laminated film (12) covering the opening (11) or the opening (11) is as described above, but is shown in FIG. 3 (a) as an example. An example in which the laminated film (12) is laminated on the front and back of the base material (2) will be described.

(Outline part by printing)
The configuration of the first contour portion (20) is a form composed of the contour element (21) formed by the printing material. As a diagram showing the configuration, as shown in FIG. 19, a contour element (21) printed with an ink of a color different from that of the base material (2) is formed on the base material (2') and laminated on the base material (2'). It shows a state in which the film (12) is covered. In this case, the contour portion (20) of the base material (2') is emphasized depending on the color of the ink to be printed, and the effect of improving visibility can be obtained. In FIG. 19, although the contour element (21) is provided on one surface of the base material (2), it may be formed on the other surface of the base material (2) (not shown). It may be formed on both sides of the material (2).

The ink used for printing the contour element (21) is not particularly limited, and process ink, spot color ink, optical change ink, fluorescent ink and the like can be used. Further, when paper is used as the base material (2), even if a watermark ink containing a resin or an oil component and looks bright under transmitted light, or a watermark ink containing a metal pigment and having an effect of blocking light is used. good.

Further, the contour element (21) may be partially different in color in the contour portion (20) without being formed in a single color. As a specific example thereof, as shown in FIGS. 20 (a) and 20 (b), the two colors may be formed in partially different colors, and the reference numerals of FIGS. 20 (a) and 20 (b) may be used. 21a) and reference numeral (21b) show examples of contour elements formed by inks of different colors. Further, as shown in FIG. 20 (c), the area ratio of the printing halftone dots may be partially different to form a gradation, or ink of three or more colors may be printed (not shown). These configurations may be combined. According to the configuration shown in FIG. 20, it is preferable to express various colors in the contour portion (20) because the authenticity of the base material (2') can be improved.

(Processing method of contour by printing)
When the contour element (21) is formed by printing, the contour element (21) may be provided after the opening (11) is provided, and the contour element (21) may be provided before the opening (11) is provided on the base material (2). It may be formed, and in the latter case, it is preferable to print on the area outside the contour portion (20) in order to allow the processing of the opening portion (11). As a means for printing the contour element (21), offset printing, flexography, gravure, screen, intaglio printing, inkjet printing machine and the like can be used.

Among the above-mentioned printing methods, the printing method that can increase the film thickness of the ink by gravure, screen, intaglio printing, and inkjet printing not only enhances the expression of the contour portion (20) by the color difference, but also makes it three-dimensional. This is a more preferable form in order to enhance the credibility of the base material (2') because it can be visually emphasized. In this case, the ink film thickness is preferably 20 μm or more. Further, considering the distribution suitability, it is preferably 50 μm or less. In this way, when the contour element (21) with the ink fill is formed, the contour portion (20) is three-dimensionally emphasized and can be visually recognized even if the ink of the same color as the base material (2) is used. , The configuration may be formed as the contour element (21) of the present invention.

In the anti-counterfeit medium (1) shown in FIG. 19, the contour element (21) formed by printing is an example formed on the base material (2), but in the present invention, the contour element formed by printing. (21) may be formed on the laminated film (12) as shown in FIG. In the configuration in which the laminated film (12) is laminated on the front and back of the base material (2), the contour element (21) formed by printing may be formed on the laminated film (12) on the front and back (shown). figure).

Regarding the configuration of the first contour portion (20), the configuration in which the contour portion (20) is provided on the contour of the base material (2') surrounded by the opening portion (11) has been described. ) May be printed on the base material (2) adjacent to the outside (the outer circumference of the donut shape) to provide a contour portion.

(Outline part with different transparency)
The configuration of the second contour portion (20) is a form utilizing the so-called watermark principle, in which the transparency changes depending on the thickness of the base material (2). As a diagram showing the configuration, FIG. 22 (a) shows white that is brightly visible under transmitted light by partially making the thickness thinner than that of the base material (2') around the contour portion (20). It shows a state in which a contour element (21) having a watermark effect is formed. In this case, when observing under transmitted light, the outline of the base material (2') is brightly emphasized, and the effect of improving the visibility of the base material (2') can be obtained. Further, in FIG. 22B, by partially increasing the thickness of the base material (2'), a contour element (21) having a black watermark effect that is visually recognized dark under transmitted light is formed. Shows the state. In this case, when observing under transmitted light, the outline of the base material (2') is darkly emphasized, and the effect of improving the visibility of the base material (2') can be obtained. As shown in FIG. 22A, the thickness of the contour element (21) is partially thinned, and as shown in FIG. 22B, the thickness is partially thickened. It is preferable that the difference between the above is 20 μm or more because it is emphasized three-dimensionally and can be visually recognized, and it is preferably 50 μm or less in consideration of the distribution suitability of the anti-counterfeit medium (1).

When the base material (2') is paper, the thickness of the base material (2') can be increased even if the paper itself is not transparent due to the basis weight, pigments, dyes and additives. If there is a difference in transparency due to the thinning, it may be used as the contour element (21), so that paper having no transparency in the paper itself may be used as the base material (2). Further, if it is a transparent paper, it can be used as a base material (2') for forming a contour element (21) having a partially different transparency. The same applies to the case where a film or plastic is used as the base material (2').

(Processing method for contours with different transparency)
As a method for forming the contour element (21), a base material (2') made of paper can be formed by a circular net, a dandy roll, or a press roll, which is a known papermaking technique. In this case, the contour element (21) may be formed by processing in advance in the papermaking process for producing the base material (2'). When a transparent film or plastic is used as the base material (2'), a part of the base material (2') is removed by laser processing to make the thickness different, and the contour elements have different transparency. (21) may be formed. Further, the base material (2') made of paper, film or plastic may be embossed to thin a part of the base material (2') to form a contour element (21) having different permeability. .. When forming the contour element (21), only the range of the contour portion (20) may be machined, and the contour portion (20) may be machined in order to allow the processing of the opening portion (11). ) It is advisable to process the area outside.

The contour element (21) formed by making the thickness of the base material (2') different is not limited to the configuration having only the effects of the white watermark and the black watermark, and the base material (20) is formed in the contour portion (20). The thickness of 2') may be partially different. As a specific example thereof, as shown in FIG. 23 (a), a contour portion (20) having the effects of both a white watermark and a black watermark may be formed, and in FIG. 23 (a), a circular base is formed. A contour formed by forming a contour element (21A) having a white watermark effect on the upper contour and a contour element (21B) having a black watermark effect on the lower contour with respect to the material (2'). An example of part (20) is shown. Further, in FIG. 23 (b), the contour element (21A) having the effect of white watermark and the contour element (21B) having the effect of black watermark are sequentially arranged around the circular base material (2'). An example of the formed contour portion (20) is shown. Further, in FIG. 23 (c), by forming the contour element (21) in which the thickness of the base material (2') is continuously different from the white watermark to the black watermark, the shade is continuously changed. An example of the visible contour portion (20) is shown. The example of the contour element (21) formed by the shaving process is not limited to the example shown in FIG. 23, and the configurations shown in FIG. 23 may be combined, and a pattern that can be processed by the shaving process, for example, It is not particularly limited to a broken line, a dotted line, a wavy line, a colored pattern, and the like. According to the configuration shown in FIG. 23, it is preferable because the authenticity of the base material (2') can be improved by expressing various shades in the contour portion (20) by observing under transmitted light. ..

(Outline part by foil)
The configuration of the third contour portion (20) is a form in which the contour element (21) is configured by the metal foil. As a diagram showing the structure, FIG. 24A shows a state in which a metal foil (P) is formed on a base material (2') and a laminated film (12) covers the metal foil (P). .. As described above, since the contour element (21) is formed along the contour of the base material (2') surrounded by the opening (11), the metal foil (P) is formed by the opening (11). It is composed of a shape surrounding the base material (2') surrounded by.

The metal foil (P) has a structure made of a metal material such as gold, silver, and aluminum. In this case, the metal foil (P) is punched out according to the shape surrounding the base material (2'), and the base material (2) is punched out. It may be laminated on') via an adhesive layer (not shown). As shown in FIG. 24 (a), the laminated film (12) may be laminated on the metal foil (P), or as shown in FIG. 24 (b), on the laminated film (12). May be laminated with a metal foil (P).

Further, an OVD in which the metal foil (P) and the laminated film (12) are integrated and the metal foil (P) is provided with a diffraction grating may be used. The OVD uses the laminated film (12) in the present invention as a supporting base material, and a laminated film (12) on which a layer made of a metal material is vapor-deposited via an embossed layer, depending on the contour of the base material (2'). The contour element (21) may be formed by demetallizing, and the contour element (21) may be laminated according to the base material (2'). As described above, when the contour element (21) is formed by the metal foil (P), the base material (2') is affected by the optical change in gloss and color under reflected light and the visual effect by OVD. Authenticity can be improved.

FIG. 24 shows an example in which the metal foil (P) is provided on only one surface of the base material (2'), but the metal foil (P) is laminated on both sides of the base material (2') to form a contour. Element (21) may be formed (not shown).

(Processing order)
In the second embodiment, when the window (10) is formed by filling the opening (11) with the transparent material (I), the order in which the contour element (21) is formed is not particularly limited and is based on the base. The contour element (21) may be formed in the material (2') and then filled with the transparent material (I), or the transparent material (I) may be filled and then the contour element (21) is formed. Further, as shown in FIG. 25 (a), a contour element (21) printed or made of a metal foil is formed on one surface of the base material (2'), and a laminated film (2) is formed on the other side of the base material (2). When the 12) is laminated or as shown in FIG. 25 (b), a contour element (21) is formed on one surface of the base material (2') by a punching process, and the other side of the base material (2) is formed. Also, when the laminated film (12) is laminated on the surface, the order of forming the contour element (21) is not limited, and the contour element (21) may be formed after laminating the laminated film (12). The laminated film (12) may be laminated after forming the contour element (21). However, in the case where the laminated film (12) is laminated on the contour element (21) formed by printing, metal foil, or punching to form the window (10) (FIGS. 19, 22, and 24). In (a)), it is necessary to first form the contour element (21) on the base material (2) and then laminate the laminated film (12) on the contour element (21). In the configuration of the third contour portion (20), when the contour element (21) is formed by the OVD in which the metal foil (P) and the laminated film (12) are integrated, the paragraph (0037) is used. The OVD and the base material (2') may be laminated in the same manner as described in the above.

Then, the contour (circular contour) of the opening (11) formed in the base material (2) was punched out to form the opening (11).

Next, a PP film (Pyrene Toyobo Co., Ltd.) having a thickness of 60 μm was used as the laminated film (12), and the punched base material (2') was attached to a predetermined position of the laminated film (12). The laminated film (12) and the opening (11) are aligned with each other, the laminated film (12) is attached to the base material (2), and the "star-shaped" base material (2') shown in FIG. 6 (e) is attached. ) Was formed.

(Example 3)
Example 3 is an anti-counterfeit medium (1) in which a window (10) is formed by ultrasonic processing, and the shape of the opening (11), that is, the window (10) is the shape shown in FIG. 26, and the opening is formed. (11) is composed of an outer "doughnut-shaped" opening (11-1) and an inner opening (11-2) having a shape surrounding the number "100". Further, as shown in FIG. 26, the base material (2'-1) surrounded by the opening (11-1) has a donut shape, and the base material (2'1) surrounded by the opening (11-2) has a donut shape. '-2) is composed of the number "100".

As the thermoplastic resin layer laminating step (S1), brown paper having a thickness of 100 μm and a basis weight of 80 g / m ² was used for the base material (2), and the thermoplastic resin layer (13) was placed on the front and back of the base material (2). As a result, a PP film with a thickness of 55 μm (Pyrene Toyobo Co., Ltd.) was attached.

In the ultrasonic processing step (S2), the mold (32) used for ultrasonic processing is made of an aluminum alloy (JIS A 7075), and has a concave first region (32A) and a convex second region (32A). The height difference of the region (32B) was 200 μm. As the design of the mold (32), the one corresponding to the shape of the base material (2') surrounded by the opening (11) and the opening (11) shown in FIG. 26 was used. Then, using an ultrasonic processing machine (W5080 stamp type manufactured by Nippon Avionics Co., Ltd.), ultrasonic processing is performed under the processing conditions of pressure 0.3 MPa, processing time 0.3 seconds, and amplitude 30 μm, and the shape shown in FIG. 26 is performed. The anti-counterfeit medium (1) of Example 3 provided with the window (10) of the above was prepared. Even when the openings (11-1, 11-2) and the substrate (2'-1, 2'-2) surrounded by the openings (11-1, 11-2) are configured in a complicated arrangement as in the third embodiment, they are super By performing ultrasonic processing, the window (10) could be easily formed.
