Description

  The present invention relates to a forgery prevention technique.

  It is desirable that authentication items such as cash cards, credit cards and passports, and securities such as gift certificates and stock certificates are difficult to counterfeit. Therefore, conventionally, a label that is difficult to counterfeit or imitation and is easy to distinguish from counterfeit or counterfeit is attached to such articles.

  In recent years, the distribution of counterfeit products has been regarded as a problem for items other than certified items and securities. Therefore, the opportunity to apply the above-described anti-counterfeiting technology with respect to certified articles and securities is increasing.

A representative example of this forgery prevention technique is the use of a color shift medium that causes a color change of reflected light, that is, a color shift, in accordance with an observation angle. For example, Patent Document 1 describes a pigment that causes a color shift and a printed matter using the same.
Special Table 2002-523606

  However, in recent years, materials exhibiting such a color shift have been used in various fields, and their acquisition has become relatively easy. Therefore, there is a possibility that a sufficient anti-counterfeit effect cannot be obtained with a forgery prevention technique that relies solely on the color shift effect of the material itself.

  Therefore, the present invention aims to solve this problem and realize a higher anti-counterfeit effect.

According to the first aspect of the present invention, a base material provided with a plurality of grooves each having an inclined surface and a vertical surface on one main surface, and covering only the inclined surface among the wall surfaces of each of the plurality of grooves. A plurality of first grooves having the same inclined direction of the inclined surface, and the inclined surfaces of the first groove having the same inclined direction. The tilt direction includes a plurality of second grooves having a rotationally symmetric relationship with respect to an axis perpendicular to the main surface, and the main surface has first irregularities formed by arranging the plurality of first grooves. a region, the plurality of second grooves display body, characterized in including that the second uneven region formed by sequences are provided.

According to the second aspect of the present invention, a color shift layer is formed on one main surface of the substrate, and then embossing is performed to provide a plurality of grooves on the main surface and the color shift at the positions of the grooves. A display body characterized by having a structure obtained by breaking a layer is provided.

  According to the third aspect of the present invention, there is provided a labeled article characterized by comprising the display according to the first or second aspect and an article supporting the display.

  According to the present invention, it is possible to achieve a higher anti-counterfeit effect.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, in each figure, the same referential mark is attached | subjected to the component which exhibits the same or similar function, and the overlapping description is abbreviate | omitted.

  FIG. 1 is a plan view schematically showing a display body according to an example of an embodiment of the present invention. 2 is a cross-sectional view taken along the line II-II of the display shown in FIG. The II-II line is parallel to the X direction shown in FIG.

  The display body 10 includes a base material 20 provided with a plurality of grooves 130 on one main surface. The light absorption layer 40 and the color shift layer 30 are formed in this order on the main surface of the substrate 20 where the grooves 130 are provided. An adhesive layer 50 is provided on the main surface opposite to the surface on which the groove 130 of the substrate 20 is provided.

  The substrate 20 may be opaque or transparent. As the opaque base material 20, for example, paper such as art paper, coated paper or high-quality paper, paperboard such as coated ball, coated manila or double-sided card, special securities paper, white polyethylene terephthalate or white vinyl chloride sheet should be used. Can do. As the transparent substrate 20, for example, polyethylene terephthalate (PET), triacetyl cellulose (TAC), polyethylene naphthalate (PEN), polycarbonate (PC), polyethylene (PE), or polypropylene (PP) can be used. . The base material 20 may have a single layer structure or a multilayer structure.

  The color shift layer 30 is a layer that causes a change in display color according to an observation angle based on diffraction, interference, or selective reflection. For example, the color shift layer 30 is formed by laminating natural mica particles, cholesteric liquid crystal, or a plurality of inorganic oxides having different refractive indexes, the surfaces of which are coated with a metal oxide mainly composed of titanium oxide and / or iron oxide. Includes optical interference film. The color shift layer 30 is formed by, for example, a gravure printing method, a printing method such as an offset printing method or a screen printing method, a coating method such as a bar coating method, a gravure method or a roll coating method, or a vapor deposition method such as a vacuum vapor deposition method. Form.

  The light absorption layer 40 absorbs the illumination light transmitted through the color shift layer 30. By providing the light absorption layer 40, the reflected light from the color shift layer 30 can be more easily visually recognized. Therefore, the above-described optical effect exhibited by the color shift layer 30 becomes more remarkable, and the forgery prevention effect of the display body 10 can be improved.

  When the substrate 20 is transparent, the light absorption layer 40 is placed on the main surface of the substrate 20 opposite to the surface on which the color shift layer 30 is formed, that is, between the substrate 20 and the adhesive layer 50. It may be provided between them. In this case, the light absorption layer 40 absorbs light transmitted through the color shift layer 30 and the substrate 20. Therefore, also in this case, the reflected light from the color shift layer 30 can be visually recognized more easily.

  The light absorption layer 40 is made of, for example, dark ink, typically black ink. The light absorption layer 40 is formed by, for example, a printing method such as a gravure printing method, an offset printing method, or a screen printing method, or a coating method such as a bar coating method, a gravure method, or a roll coating method.

  The light absorption layer 40 may be omitted from the display body 10.

  The adhesive layer 50 has a function of adhering the display body 10 and the article when the display body 10 is supported by the article whose authenticity is to be confirmed. The adhesive layer 50 contains, for example, a vinyl chloride-vinyl acetate copolymer, or a polyester, polyamide, acrylic, butyl rubber, natural rubber, silicon, or polyisobutyl adhesive. This adhesive layer 50 comprises alkyl methacrylate, vinyl ester, acrylonitrile, aggregating components such as styrene or vinyl monomer, unsaturated carboxylic acid, hydroxy group-containing monomer or modifying component such as acrylonitrile, polymerization initiator, plasticizer, curing agent, It may further contain a curing accelerator or an antioxidant. The adhesive layer 50 can be formed by, for example, a gravure printing method, an offset printing method, or a screen printing method.

  The adhesive layer 50 may be omitted from the display body 10. In this case, the display body 10 is supported by another method on the article whose authenticity is to be confirmed.

  The display body 10 includes a flat area 110 and an uneven area 120.

  The flat region 110 has a flat surface 111. The flat surface 111 is composed of the color shift layer 30. That is, the flat region 110 is a region that exhibits a normal color shift effect.

  The uneven area 120 has a groove 130. The length direction of the groove 130 is parallel to the Y direction shown in FIG. The groove 130 is typically provided continuously in a direction intersecting the length direction thereof.

  The groove 130 has, for example, a right triangular prism shape whose height direction is perpendicular to the Z direction. Each groove 130 has an inclined surface 131 that is inclined with respect to the main surface of the substrate 20 and a vertical surface 132 that is substantially perpendicular to the main surface of the substrate 20. Hereinafter, the inclination angle of the inclined surface 131 with respect to the main surface of the substrate 20 is defined as θ (0 ° <θ <90 °).

  The inclined surface 131 is made of the color shift layer 30 as with the flat surface 111 of the flat region 110. On the other hand, the vertical surface 132 is not covered with the color shift layer 30 and is made of the exposed base material 20.

  When the surface provided with the groove 130 of the display body 10 is observed from the front direction of the inclined surface 131, the inclined surface 131 made of the color shift layer 30 is visually recognized as compared with the vertical surface 132 made of the base material 20. Easy. On the other hand, when the surface provided with the groove 130 of the display body 10 is observed from a direction parallel to the inclined surface 131, the vertical surface 132 made of the base material 20 is compared with the inclined surface 131 made of the color shift layer 30. And easy to see.

  Accordingly, the regions 110 and 120 of the display 10 produce different color shifts as described below.

  FIG. 3 is a schematic diagram illustrating an example of a color change that occurs in each region of the display body 10 illustrated in FIGS. 1 and 2 in accordance with a change in observation angle.

  FIG. 3A shows an example of the color exhibited by the display body 10 when the display body 10 is observed from the front direction of the flat surface 111, that is, the direction parallel to the vertical surface 132 (observation direction 2A shown in FIG. 2). . In this case, in the concavo-convex region 120, the inclined surface 131 made of the color shift layer 30 is visible, but the vertical surface 132 is not visible or difficult.

  At this time, the flat region 110 exhibits a color (for example, magenta) corresponding to the case where the reflection angle of the reflected light from the color shift layer 30 is about 0 °. On the other hand, the uneven area 120 exhibits a color (for example, green) corresponding to the case where the reflection angle of the reflected light from the color shift layer 30 is approximately θ. Therefore, as illustrated in FIG. 3A, the flat region 110 and the uneven region 120 are observed as regions of different colors.

  FIG. 3B shows an example of the color exhibited by the display body 10 when the display body 10 is observed from the front direction of the inclined surface 131 (observation direction 2B shown in FIG. 2). In this case, in the concavo-convex region 120, the inclined surface 131 made of the color shift layer 30 is visible, but the vertical surface 132 is not visible or difficult.

  At this time, the flat region 110 exhibits a color (for example, green) corresponding to the case where the reflection angle of the reflected light from the color shift layer 30 is approximately θ. On the other hand, the uneven area 120 exhibits a color (for example, reddish purple) corresponding to the case where the reflection angle of the reflected light from the color shift layer 30 is about 0 °. Therefore, as illustrated in FIG. 3B, each of the flat region 110 and the uneven region 120 exhibits colors that are opposite to those in the case illustrated in FIG. 3A.

  FIG. 3C shows an example of the color exhibited by the display body 10 when the display body 10 is observed from a direction parallel to the inclined surface 131 (observation direction 2C shown in FIG. 2). In this case, in the concavo-convex region 120, the vertical surface 132 made of the substrate 20 is visible, but the inclined surface 131 is not visible or difficult.

  At this time, the flat region 110 exhibits a color (for example, green) corresponding to the case where the reflection angle of the reflected light from the color shift layer 30 is about (90 ° −θ). On the other hand, the uneven region 120 exhibits the color of the base material 20 (for example, white), or is opposite to the main surface on which the base material 20 is transparent and the color shift layer 30 of the base material 20 is formed. When the light absorption layer 40 is further provided on the main surface, the color of the light absorption layer 40 (for example, black) is exhibited. Therefore, as illustrated in FIG. 3C, the flat region 110 and the uneven region 120 exhibit different combinations of colors from those shown in FIGS. 3A and 3B. In particular, in this case, the concavo-convex region 120 does not exhibit the gloss and color characteristic of the color shift material. Therefore, compared with the case where the display body 10 does not include the surface on which the base material 20 is exposed and the entire surface is covered with the color shift layer 30, it is easier to identify the genuine product.

  When the base material 20 is transparent, you may provide the printing layer which displays information, such as a character or a pattern, in the main surface on the opposite side to the side in which the color shift layer 30 was formed. In this case, the information can be visually recognized through the vertical surface 132 of the uneven region 120. Therefore, the forgery prevention effect of the display body 10 can be further improved.

  Here, the depth of the groove 130, that is, the height of the vertical surface 132 is, for example, about twice or more the thickness of the color shift layer 30. When the depth of the groove 130 is small, the base material 20 cannot be exposed on the vertical surface 132, and there is a possibility that a sufficient forgery prevention effect cannot be exhibited.

  In the above description, the groove 130 has a right triangular prism shape. However, the shape of the groove 130 is such that the uneven region 120 is not covered with the color shift layer 30 and the color shift layer 30 and the base is not covered. As long as the material 20 has an exposed surface, it can have any shape. For example, the groove 130 may have a triangular prism shape other than a right triangular prism shape, or may have another polygonal column shape. Further, the display body 10 may be provided with a recess other than the groove instead of the groove 130. For example, cone-shaped concave portions such as a cone and a quadrangular pyramid may be provided, and truncated column-shaped concave portions such as a truncated cylinder and a truncated square column may be provided.

  You may provide the recessed part which has the surface coat | covered with the color shift layer 30, and the surface which is not coat | covered with the color shift layer 30, but the base material 20 was exposed.

  The display body 10 may further include a protective layer as an outermost layer that covers the color shift layer 30. The protective layer has a function of reducing damage to the display body 10 and / or deterioration due to light, and suppressing mold making by a forger.

  As the protective layer, for example, a resin such as polyester or acrylic can be used. The protective layer may further contain, for example, a UV absorber or a lubricant such as polyethylene wax. This protective layer is formed by, for example, a gravure printing method, an offset printing method, or a screen printing method. In addition, you may add a leveling agent or an antifoamer etc. further in the case of application | coating.

  This display body 10 is manufactured as follows, for example.

  First, the light absorption layer 40 and the color shift layer 30 are laminated in this order on one main surface of the substrate 20. Next, the embossed plate provided with corrugated convex portions having a triangular wave-like cross-sectional shape, for example, is pressed against the surface on the color shift layer 30 side, thereby generating concave portions corresponding to the convex portions of the embossed plate, The light absorption layer 40 and the color shift layer 30 are broken. Specifically, by embossing, an inclined surface 131 in which the base material 20 is covered with the color shift layer 30 and a vertical surface 132 in which the base material 20 is not covered with the color shift layer 30 and the base material 20 is exposed. Cause it to occur. Subsequently, the adhesive layer 50 is formed on the other main surface of the substrate 20. The display body 10 is obtained as described above.

  Prior to the above embossing process, a smoothing process by calendaring may be performed. By this treatment, the optical effect exhibited by the color shift layer 30 can be made more remarkable.

  FIG. 4 is a plan view schematically showing a display body according to another example of the aspect of the present invention. FIG. 5 is a cross-sectional view taken along the line VV of the display shown in FIG. The VV line is parallel to the X direction shown in FIG.

  In the display 10 shown in FIGS. 4 and 5, two types of grooves 130 </ b> A and 130 </ b> B having different inclination directions are provided in the uneven region 120, and the uneven region 120 has two types of regions, that is, the first uneven region 120 </ b> A and Except for the second uneven region 120B, it has the same configuration as the display 10 shown in FIGS. The groove 130A includes an inclined surface 131A and a vertical surface 132A, and the groove 130B includes an inclined surface 131B and a vertical surface 132B. Here, as an example, a case will be described in which the inclined directions of the inclined surfaces 131A and 131B are rotationally symmetric with respect to the Z axis shown in FIGS. 4 and 5, and the inclined angles of the inclined surfaces 131A and 131B are both 45 °. .

  FIG. 6 is a schematic diagram illustrating an example of a color change that occurs in each region of the display body 10 illustrated in FIGS. 4 and 5 in accordance with a change in observation angle.

  FIG. 6A shows an example of the color exhibited by the display body 10 when the display body 10 is observed from the front direction of the flat surface 111, that is, the direction parallel to the vertical surfaces 132A and 132B (observation direction 5A shown in FIG. 5). ing. In this case, in the first uneven region 120A and the second uneven region 120B, the inclined surfaces 131A and 131B made of the color shift layer 30 are visible, but the vertical surfaces 132A and 132B are invisible or difficult.

  At this time, the flat region 110 exhibits a color (for example, magenta) corresponding to the case where the reflection angle of the reflected light from the color shift layer 30 is about 0 °. On the other hand, the first uneven area 120A and the second uneven area 120B exhibit a color (for example, green) corresponding to the case where the reflection angle of the reflected light from the color shift layer 30 is 45 °. Therefore, as illustrated in FIG. 6A, the flat region 110, the first uneven region 120A, and the second uneven region 120B are observed as regions of different colors. In particular, in this case, the first uneven region 120A and the second uneven region 120B exhibit the same color. Therefore, it is not visually recognized that the uneven region 120 is composed of a plurality of regions only by observing the display body 10 from the front.

  FIG. 6B shows an example of the color exhibited by the display body 10 when the display body 10 is observed from the front direction of the inclined surface 131A (observation direction 5B shown in FIG. 5). In this case, in the first uneven region 120A, the inclined surface 131A made of the color shift layer 30 is visible, but the vertical surface 132A is not visible or difficult. In the second uneven area 120B, the vertical surface 132B made of the substrate 20 is visible, but the inclined surface 131B is not visible or difficult.

  At this time, the flat region 110 exhibits a color (for example, green) corresponding to the case where the reflection angle of the reflected light from the color shift layer 30 is about 45 °. 120 A of 1st uneven | corrugated | grooved areas exhibit the color (for example, reddish purple) corresponding to the case where the reflection angle of the reflected light from the color shift layer 30 is about 0 degree. Moreover, the 2nd uneven | corrugated area | region 120B exhibits the color (for example, white or black) of the base material 20 or the light absorption layer 40. FIG. Therefore, as illustrated in FIG. 6B, the flat region 110, the first uneven region 120A, and the second uneven region 120B exhibit different colors. In this case, since the first uneven region 120A and the second uneven region 120B exhibit different colors, it is visually recognized that the uneven region 120 includes a plurality of regions.

  FIG. 6C shows an example of the color exhibited by the display body 10 when the display body 10 is observed from the front direction of the inclined surface 131B (observation direction 5C shown in FIG. 5). In this case, among the first uneven regions 120A, the vertical surface 132A made of the substrate 20 is visible, but the inclined surface 131A is not visible or difficult. In the second uneven region 120B, the inclined surface 131B made of the color shift layer 30 is visible, but the vertical surface 132B is not visible or difficult.

  At this time, the flat region 110 exhibits a color (for example, green) corresponding to the case where the reflection angle of the reflected light from the color shift layer 30 is about 45 °. 120 A of 1st uneven | corrugated | grooved areas exhibit the color (for example, white or black) of the base material 20 or the light absorption layer 40. FIG. Further, the second uneven region 120B exhibits a color (for example, reddish purple) corresponding to the case where the reflection angle of the reflected light from the color shift layer 30 is about 0 °. Therefore, as illustrated in FIG. 6C, the first uneven region 120 </ b> A and the second uneven region 120 </ b> B exhibit colors that are opposite to those in the case illustrated in FIG. 6B. Also in this case, since the first uneven region 120A and the second uneven region 120B exhibit different colors, it is visually recognized that the uneven region 120 is composed of a plurality of regions.

  In addition, the uneven | corrugated area | region 120A and 120B may differ in the inclination angle of the groove | channel 130, a length direction, or the arrangement direction. Moreover, the uneven | corrugated area | region 120 may further contain the other area | region from which the inclination angle of the groove | channel 130, an inclination direction, a length direction, or an arrangement | sequence direction etc. differ. In this case, the display body 10 exhibits a more complicated visual effect.

  The display body 10 can be manufactured by the same method as described for the display body 10 shown in FIGS. 1 and 2 except for the embossing process. This embossing process can be performed using, for example, an embossing plate provided with convex portions corresponding to the plurality of grooves 130A and 130B shown in FIG.

  FIG. 7 is a plan view schematically showing an example of a labeled article including the display body described with reference to FIGS. 1 to 6. The labeled article 200 includes an article 201 and a display body 10.

  The article 201 is an article whose authenticity is to be confirmed. The article 201 is, for example, an authentication medium such as a cash card, a credit card, and a passport, or a securities medium such as a gift certificate and a stock certificate. The article 201 may be an article other than the authentication medium and the securities medium. For example, the article 201 may be a craft or a work of art. Alternatively, the article 201 may be a packaged product including a package and contents contained therein.

  The display body 10 is supported by the article 201. For example, the display body 10 is attached to the article 201.

  The display body 10 may be supported on the article 201 by another method.

  For example, when the article 201 includes paper, the display body 10 may be embedded in the paper. In this case, the labeled article 200 can be obtained, for example, by sandwiching the display body 10 between fiber layers during paper making and then performing printing or the like on the paper as necessary. In addition, in order to improve the visibility of the display body 10, you may provide an opening in the part which has coat | covered the front surface of the display body 10 among paper. Moreover, there is no restriction | limiting in particular in the shape of the display body 10 embedded in paper. For example, the thread-like display body 10 may be embedded in paper.

  The display body 10 may be supported by the article 201 by attaching a tag including the display body 10 to the article 201. If it is difficult for a general user to replace the tag on the article 201, the display 10 is sufficiently useful for confirming the authenticity of the article 201.

  Moreover, said technique demonstrated about the display body 10 is applicable also to transfer foil or a transfer sheet.

  The display body 10 may be used for purposes other than forgery prevention. For example, the display body 10 can be used as a toy, a learning material, or a decoration.

  Examples of the present invention will be described below, but the present invention is not limited thereto.

(Example 1)
Instead of forming the adhesive layer 50 and forming the light absorbing layer 40 between the base material 20 and the color shift layer 30, the main surface of the base material 20 opposite to the main surface on which the color shift layer 30 is formed. A display body similar to that described with reference to FIGS. 1 and 2 was produced except that it was formed on the surface.
