Description

  The present invention relates to a display technique that provides, for example, an anti-counterfeit effect.

  OVD (Optical Variable Device) such as holograms, diffraction gratings, and multilayer films may be used as anti-counterfeiting means. The OVD displays a stereoscopic image or a decoration image using light interference. The image displayed by the OVD causes a color change corresponding to the observation angle, so-called color shift.

  In addition to having such a unique visual effect, OVD requires advanced techniques for its manufacture. Therefore, OVD is used as a display for preventing counterfeiting in credit cards, securities, certificates and the like. In recent years, OVD has also been used in authentication seals for certifying products such as sporting goods, computer parts, and software products, and software packages, or sealing seals for sealing packages of the products. Became.

  Thus, OVD is used in various articles in order to achieve a high anti-counterfeit effect. OVD is also widely used for purposes other than anti-counterfeiting effects such as decorative effects.

  However, as a result of the widespread use of OVD, it has become easier to process commercially available OVD to obtain visual effects similar to authentic products. If an OVD is used that has a visual effect similar to the authentic product, it is difficult to see that it is a counterfeit product.

  Patent Document 1 describes a transfer foil in which a peeling layer, a hologram forming layer, a transmissive thin film layer, a printing layer, a reflective thin film layer, and an adhesive layer are sequentially laminated on a support. A transfer material layer composed of a hologram forming layer, a transmissive thin film layer, a printing layer, a reflective thin film layer, and an adhesive layer or a part thereof is transferred from a support onto an article and used as a display.

  In this display body, the printing layer is interposed between the hologram forming layer and the article. Therefore, a part of the hologram forming layer is not hidden by the printing layer. Therefore, it is possible to display a hologram image over the entire hologram forming layer.

  In addition, the superimposition of the image displayed by the print layer and the hologram image achieves a visual effect that is impossible only with the hologram. And when fluorescent ink is used as the material of the printing layer, it is difficult to realize the existence of the printing layer itself. Therefore, this display body achieves a high anti-counterfeit effect.

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

First, the first aspect of the present invention will be described.
FIG. 1 is a plan view schematically showing a display body according to the first embodiment of the present invention. 2 is a cross-sectional view taken along the line II-II of the display shown in FIG.

  In FIG. 1, the front surface of the display body 10, that is, the display surface that should face the observer is depicted. 1 and 2, the X direction and the Y direction are parallel to the front surface of the display body 10 and orthogonal to each other. The Z direction is a direction perpendicular to the X direction and the Y direction.

  The display body 10 shown in FIGS. 1 and 2 is an element that can be used for preventing forgery, for example. As shown in FIG. 2, the display body 10 includes a front masking layer 11 and a plurality of regions 12a and 12b.

  When the front hiding layer 11 is illuminated from the front side, each pattern of the regions 12a and 12b located on the back side of the front hiding layer 11 is perceived by an observer observing from the front side. To prevent. The front masking layer 11 has, for example, metallic luster, and reflects a part of the illumination light specularly when illuminated from the front side. The front masking layer 11 may have light scattering properties.

  In addition, the front concealment layer 11 is light transmissive. The transmittance of the front hiding layer 11 is, for example, in the range of 5% to 80%, and typically in the range of 30% to 60%.

  The front masking layer 11 contains a metal. For example, the front hiding layer 11 is a metal layer made of a single metal or an alloy. As a material for the metal layer, for example, aluminum, iron, magnesium, zinc, gold, silver, chromium, nickel, copper, or an alloy containing one or more of them is used.

  This metal layer is, for example, a patterned layer. In this case, the metal layer is, for example, a layer composed of a plurality of islands spaced apart from each other, or a layer provided with a plurality of openings in a mesh shape. When this structure is adopted, for example, a desired transmittance can be achieved by appropriately setting the area ratio of the openings in the metal layer.

  The patterned metal layer is formed, for example, by forming a pattern made of a resin soluble in a processing liquid on a base, and then depositing a thin film made of a metal or an alloy on the base, and then dissolving the resin pattern in the processing liquid. Obtained by removing the metal or alloy thereon. Alternatively, the patterned metal layer forms a thin film as a continuous film made of a metal or an alloy, a resin pattern is formed on the thin film, and the thin film is etched with acid or alkali using the resin pattern as a mask. Can be obtained. Here, the term “continuous film” means a film that spreads across a surface without a gap such as an opening or a cut, that is, a “solid film”. The resin pattern may be formed by printing or may be formed using photolithography.

  The metal layer can be formed without patterning. For example, according to a vapor deposition method such as a vacuum evaporation method and a sputtering method, a metal or alloy first forms a layer composed of a plurality of islands spaced apart from each other, and then provides a plurality of openings in a mesh shape. The formed layer is formed, and then a continuous film is formed. Therefore, if the deposition is completed at an initial stage, a metal layer composed of a plurality of islands spaced apart from each other or a metal layer provided with a plurality of openings in a mesh shape can be obtained. Further, the metal layer may be a continuous film as long as it is sufficiently thin. When utilizing vapor deposition, the thickness of the metal layer is typically in the range of about 5 nm to about 1000 nm, depending on the optical properties of the material to be deposited.

  The front concealment layer 11 may be formed using a metallic gloss ink in which a metal piece or an alloy piece is dispersed in a resin. Desirable transmittance can be achieved by appropriately setting the ratio of the metal piece or alloy piece to the resin and the thickness of the front masking layer 11. In addition, since the printing method is used, it is easy to form the front masking layer 11 having a complicated shape, and it is also easy to cause a distribution in the transmittance of the front masking layer 11. . That is, high designability can be easily achieved. Note that the term “metal-containing layer” used below implies the above-described metal layer and a layer obtained using a metallic gloss ink.

  The front masking layer 11 may include a laminate of a metal-containing layer and a colored layer containing a dye and / or a pigment. For example, when the metal-containing layer scatters light in a certain wavelength range, the use of a colored layer that absorbs light in this wavelength range can enhance the metallic luster of the front masking layer 11. In addition, the material similar to the colored layer mentioned later regarding the area | regions 12a and 12b is used for the material of this colored layer, for example.

  The metal-containing layer and the colored layer may have the same shape or different shapes. When the shapes of the metal-containing layer and the colored layer are different, an image corresponding to the overlapping portion and the non-overlapping portion of the metal-containing layer and the colored layer can be displayed on the display body 10.

  The front masking layer 11 may include a laminate of a metal-containing layer and a multilayer film. The multilayer film is composed of a plurality of transparent dielectric layers each having an optical thickness set appropriately. When this multilayer film is irradiated with, for example, white light, constructive interference and destructive interference occur in the multilayer film, and transmission and reflection spectra corresponding to the optical thickness and the like are obtained. Therefore, when the metal-containing layer and the multilayer film are combined, a visual effect that cannot be achieved with the metal-containing layer alone can be achieved.

Examples of the material for the transparent dielectric layer include Sb ₂ O ₃ (3.0), Fe ₂ O ₃ (2.7), TiO ₂ (2.6), CdS (2.6), and CeO ₂ (2 .3), ZnS (2.3), PbCl ₂ (2.3), CdO (2.2), Sb ₂ O ₃ (2.0), WO ₃ (2.0), SiO (2.0) , Si ₂ O ₃ (2.5), In ₂ O ₃ (2.0), PbO (2.6), Ta ₂ O ₃ (2.4), ZnO (2.1), ZrO ₂ (2. 0), MgO (1.6), SiO ₂ (1.5), MgF ₂ (1.4), CeF ₃ (1.6), CaF ₂ (1.3 to 1.4), AlF ₃ (1 .6), inorganic compounds such as Al ₂ O ₃ (1.6) and GaO (1.7) are used. Alternatively, an organic compound such as polyethylene (1.51), polymethyl methacrylate (1.51), and polystyrene (1.60) may be used as the material for the transparent dielectric layer. The numerical value written in parentheses after the compound name represents the refractive index of the compound.

  The metal-containing layer and the multilayer film may have the same shape or different shapes. When the shapes of the metal-containing layer and the multilayer film are different, an image corresponding to the overlapping portion and the non-overlapping portion of the metal-containing layer and the multilayer film can be displayed on the display body 10.

  The regions 12 a and 12 b face the back surface of the front hiding layer 11. The regions 12 a and 12 b are adjacent to each other in a direction parallel to the back surface of the front hiding layer 11. In this example, the region 12b has a shape corresponding to the character string “TP”. In FIG. 1, the display portion Aa is a portion corresponding to the region 12a on the display surface, and the display portion Ab is a portion corresponding to the region 12b on the display surface.

  The regions 12a and 12b exhibit different transmittances when irradiated with polarized light having any wavelength in the visible light region as illumination light, or emit different polarized light as transmitted light. The “polarized light different from each other” refers to two selected from the group consisting of linearly polarized light, elliptically polarized light and circularly polarized light, two linearly polarized light whose at least one of the vibration direction and intensity of the electric field vector is different from each other, and the short axis of the ellipse Two elliptical polarizations in which at least one of the ratio of the major axis to the ellipse, the orientation of the major axis of the ellipse, the intensity and the rotation direction of the electric field vector is different from each other, and Contains.

  In this example, the regions 12a and 12b are colored layers that exhibit different transmittances when irradiated with natural light having any wavelength in the visible light region as illumination light. Specifically, the region 12a has a higher transmittance with respect to any light component that the front concealment layer 11 transmits in the visible light compared to the region 12b. In addition, each of the regions 12 a and 12 b typically has a lower reflectance than the front concealment layer 11.

  The colored layer is made of, for example, a mixture of a binder resin and a dye and / or pigment. The ratio of dyes and pigments in the mixture is, for example, in the range of 0.1% to 80%. When this ratio is small, coloring of transmitted light may be insufficient. If this proportion is large, the strength of the layer obtained from the previous mixture may be insufficient.

  Examples of the dye include C.I. I. Direct Red 2 and C.I. I. Direct dyes such as Direct Red 28, C.I. I. Acid dyes such as Acid Orange 7, C.I. I. Basic dyes such as Basic Blue 9, or C.I. I. Disperse Yellow7 and C.I. I. Disperse dyes such as Disperse Violet 1 are used. Moreover, you may use what is obtained by chemically modifying the pigment | dye which functions as a pigment like phthalocyanine, and shows the behavior as a dye. As the dye, one kind of compound may be used, or a plurality of kinds of compounds may be mixed and used.

  As the pigment, for example, inorganic pigments such as zinc white, titanium dioxide, petiole and carbon black, or organic pigments such as anthraquinone, quinacridone, perylene, quinophthalone and phthalocyanine are used. As the pigment, one kind of compound may be used, or a plurality of kinds of compounds may be mixed and used.

  The colored layer is formed by a printing method such as a gravure method or a screen printing method. The thickness of the colored layer is, for example, in the range of 0.1 μm to 50 μm.

  A multilayer film may be used as the colored layer. For example, both the regions 12a and 12b may be multilayer films. Alternatively, one of the regions 12a and 12b may be a mixture of a binder resin and a dye and / or pigment, and the other of the regions 12a and 12b may be a multilayer film.

  One of the regions 12a and 12b may not be a colored layer. For example, the region 12b may be a colorless layer that is transparent or has light scattering properties, and may be a void or an opening provided in the region 12a.

  Here, as an example, it is assumed that both the regions 12a and 12b are colored layers made of a mixture of a binder resin and a dye and / or pigment.

  The display body 10 is supported on an article, for example. When the article includes a transparent portion at a position where the display body 10 is to be supported, typically, the display body 10 is provided with a back surface hiding layer similar to the front surface hiding layer 11 and the regions 12a and 12b interposed therebetween. It is provided so as to face the front concealing layer 11 with being sandwiched.

  When this display 10 is supported by an article, for example, an adhesive label or a transfer foil described below is used.

FIG. 3 is a cross-sectional view schematically showing an example of an adhesive label.
The pressure-sensitive adhesive label 2 shown in FIG. 3 includes a display body 10 and a pressure-sensitive adhesive layer 20a.

  The display body 10 included in the adhesive label 2 is the same as the display body 10 described with reference to FIGS. 1 and 2 except that the following configuration is adopted. That is, the display body 10 further includes a base material 13 facing the regions 12a and 12b with the front masking layer 11 interposed therebetween. The base material 13 has light transmittance. The substrate 13 may be light scattering, but is typically transparent. The base material 13 consists of resin, for example.

The adhesive layer 20 a covers the back surface of the display body 10.
The adhesive layer 20a is made of an adhesive such as a pressure sensitive adhesive. As the pressure-sensitive adhesive, for example, a vinyl chloride-vinyl acetate copolymer, a polyester-based polyamide, or an acrylic, butyl rubber-based, natural rubber-based, silicon-based or polyisobutyl-based pressure-sensitive adhesive is used.

  The pressure-sensitive adhesive may further contain an additive. Examples of the additive include aggregating components such as alkyl methacrylate, vinyl ester, acrylonitrile, styrene, and vinyl monomer; modifying components such as unsaturated carboxylic acid, hydroxy group-containing monomer, and acrylonitrile; polymerization initiator; plasticizer; A curing agent; a curing accelerator; an antioxidant; or a mixture containing two or more thereof is used.

  The adhesive layer 20a is obtained, for example, by printing or applying an adhesive on the back surface of the display body 10. For printing or application of the adhesive, for example, a printing method such as a gravure printing method, an offset printing method and a screen printing method, or a coating method such as a bar coating method, a gravure method and a roll coating method is used.

  The display body 10 can be provided with the adhesive layer 20a by other methods. For example, the adhesive layer 20a may be formed on the separator, and the adhesive layer 20a may be transferred from the separator onto the display body 10.

  The adhesive label 2 is normally supported in a peelable manner on a support 30a such as a release paper and a release film before being attached to an article. That is, this adhesive label 2 is normally handled as an adhesive label with a mount before being attached to an article. When the display body 10 is supported by the article, the pressure-sensitive adhesive label 2 is peeled off from the support body 30a, and this is attached to the article so that the display body 10 faces the article with the adhesive layer 20a interposed therebetween.

  When this configuration is adopted, the display body 10 may be provided with a cut so that the display body 10 is destroyed when the adhesive label 2 is about to be peeled off from the article. Alternatively, a distribution of interlayer adhesion strength may be formed. If it carries out like this, when it is going to peel the adhesive label 2 from articles | goods, a brittle fracture | rupture can be produced in the boundary of a part with a strong interlayer adhesive strength, and a weak part.

FIG. 4 is a cross-sectional view schematically showing an example of the transfer foil.
The transfer foil 3 shown in FIG. 4 includes a transfer material layer 10 ′, an adhesive layer 20b, and a support 30b.

  The transfer material layer 10 ′ includes a transfer portion and a non-transfer portion that are adjacent to each other. In FIG. 4, the boundary between the transfer portion and the non-transfer portion is indicated by a broken line.

  The transfer portion is the same as the display body 10 described with reference to FIGS. 1 and 2 except that the transfer portion further includes a peeling protective layer 14 facing the regions 12a and 12b with the front masking layer 11 interposed therebetween. is there. On the other hand, the non-transfer portion typically has a stacked structure similar to that of the transfer portion. The non-transfer portion may not have the same laminated structure as the transfer portion. The non-transfer portion can be omitted.

  The peeling protective layer 14 has light transmittance. The release protective layer 14 may be light scattering, but is typically transparent. The peeling protection layer 14 is made of a resin, for example.

  The peeling protective layer 14 has a weaker adhesive strength to the support 30 b than the adhesive strength to the front concealing layer 11. The peeling protection layer 14 serves to facilitate peeling of the transfer portion from the support 30b and to protect the peeled transfer portion, that is, the front concealing layer 11 of the display body 10 from damage and deterioration. The peeling protective layer 14 can be omitted.

  The adhesive layer 20b covers the back surface of the transfer material layer 10 '. The adhesive layer 20b is made of, for example, a thermoplastic resin.

  The support 30b supports the front surface of the transfer material layer 10 'in a peelable manner. The support 30b is made of resin, for example. The support 30b has a higher glass transition temperature than the adhesive layer 20b.

  When this transfer foil 3 is used, the display body 10 can be attached to the article using, for example, a hot stamp. That is, first, the transfer foil 3 and the article are arranged so that the adhesive layer 20b faces the article, and they are aligned so that the transfer portion faces the transfer position of the article. Next, in this state, the portion corresponding to the transfer portion of the transfer foil 3 is sandwiched between them, the heated stamp head is pressed against the article, and the adhesive layer 20b is placed at the position sandwiched between the stamp head and the article. Plasticize. The stamp head is then moved away from the article and subsequently the transfer foil is pulled away from the article. This causes brittle fracture of the adhesive layer 20b and the transfer material layer 10 'along the boundary between the transfer portion and the non-transfer portion. In this way, the transfer portion is transferred from the support 30b onto the article.

Next, the labeled article including the display body 10 will be described.
FIG. 5 is a plan view schematically showing an example of a labeled article including the display body shown in FIGS. 1 and 2. 6 is a cross-sectional view taken along the line VI-VI of the labeled article shown in FIG.

  The labeled article 1 shown in FIGS. 5 and 6 includes a display body 10, an adhesive or adhesive layer 20, and an article 40.

  The display body 10 is the same as the display body 10 described with reference to FIGS. 1 and 2. The display body 10 may further include a base material 13 as described with reference to FIG. Alternatively, the display body 10 may further include a peeling protective layer 14 as described with reference to FIG.

  The adhesive or adhesive layer 20 covers the back surface of the display body 10. The adhesive or adhesive layer 20 is, for example, the adhesive layer 20a described with reference to FIG. The adhesive or adhesive layer 20 may be the adhesive layer 20b described with reference to FIG. When the display body 10 can be supported on the article without the adhesive or adhesive layer 20, the adhesive or adhesive layer 20 can be omitted.

  The article 40 supports the display body 10 with the adhesive or adhesive layer 20 interposed therebetween. At least a part of the part that supports the display body 10 of the article 40 has light transmittance.

  This light transmissive portion is typically opaque. When this portion is opaque, the patterns of the regions 12a and 12b described with reference to FIGS. 1 and 2 can be prevented from being perceived by the observer who is observing from the back side. This opaque portion can be constituted by, for example, paper, a plastic layer containing a pigment, or a glass plate supporting at least one of them.

  The light transmissive part may be transparent. If the display body 10 includes the above-described back masking layer, each pattern of the regions 12a and 12b can be prevented from being perceived by the observer who is observing from the back side. In addition, when the part which has a light transmittance is transparent, the display body 10 may be supported by the article 40 so as to face the observer with the article 40 interposed therebetween.

Next, an image displayed by the display body 10 will be described.
FIG. 7 is a plan view schematically showing an image displayed by the display body when the labeled article shown in FIGS. 5 and 6 is illuminated from the front side. FIG. 8 is a plan view schematically showing an image displayed by the display body when the labeled article shown in FIGS. 5 and 6 is illuminated from the back side. 7 and 8, reference numeral 50 indicates a light source.

  As shown in FIG. 7, when the display body 10 is illuminated from the front side, a part of the illumination light is reflected by the front hiding layer 11 of the display body 10 and the other part is absorbed by the front hiding layer 11 and remains. Passes through the front concealing layer 11. Part of the light transmitted through the front concealing layer 11 is absorbed by the region 12a or 12b, the other part is transmitted through the region 12a or 12b, and the rest is reflected by the region 12a or 12b. The light reflected by the regions 12a and 12b is different in intensity or spectrum, but these reflected lights are relatively low in intensity, and only a part of them can pass through the front concealing layer 11.

  That is, the reflected light from the regions 12a and 12b emitted from the display body 10 is much lower in intensity than the light reflected from the front masking layer 11 forward. Therefore, even if the intensity or spectrum of the light reflected by the regions 12a and 12b is different from each other, an observer who is observing the display body 10 from the front side cannot distinguish the difference. Accordingly, the display portion Aa corresponding to the region 12a and the display portion Ab corresponding to the region 12b look the same color, and the display body 10 does not display the character string “TP”.

  As shown in FIG. 8, when the display body 10 is illuminated from the back side with the article 40 and the adhesive or adhesive layer 20 sandwiched therebetween, a part of the illumination light causes the article 40 and the adhesive or adhesive layer 20 to be The light passes through in sequence and enters the region 12a or 12b. Part of this incident light is transmitted through the region 12 a or 12 b, and further part of it is transmitted through the front concealment layer 11.

  Under such conditions, only light transmitted through the regions 12a and 12b contributes to the display for an observer observing the display 10 from the front side. The light transmitted through the regions 12a and 12b has different intensities or spectra. Therefore, the display portion Aa corresponding to the region 12a and the display portion Ab corresponding to the region 12b look different colors. Therefore, in this case, the display body 10 displays the character string “TP”.

  Thus, the regions 12a and 12b form a latent image, and the latent image is visualized under special conditions. Since the regions 12a and 12b are concealed by the front concealment layer 11, the latent image is not visualized under normal observation conditions. Therefore, it is difficult to realize that the regions 12a and 12b form a latent image. Therefore, according to this technique, a high anti-counterfeit effect can be achieved.

  The regions 12a and 12b typically display colors that can be distinguished from each other when the transmitted light is observed with the naked eye with white light. In this case, the regions 12a and 12b usually display colors that can be distinguished from each other even when the reflected light is illuminated with white light and observed with the naked eye. Therefore, when the reflectance of the regions 12a and 12b and the transmittance of the front concealing layer 11 are high, the latent image may be visualized by illuminating the display body 10 from the front side.

  If the regions 12a and 12b display colors that are indistinguishable or difficult to distinguish from each other when illuminated with white light and the reflected light is observed with the naked eye, the reflectance of the regions 12a and 12b and the front concealment layer 11 are displayed. Even if the transmittance is high, the latent image is not visualized by illuminating the display 10 from the front side. Further, when this configuration is adopted, even if the regions 12a and 12b display colors that are impossible or difficult to distinguish from each other when illuminated with white light and the transmitted light is observed with the naked eye, the region 12a If the spectrum of the light transmitted by 12b and 12b is different, for example, by using a light source with a narrow wavelength range instead of a white light source or by limiting the wavelength range of illumination light by using an optical filter such as a multilayer film The latent image can be visualized.

  That is, when this configuration is adopted, the latent image is not visualized under the normal observation conditions for observing the reflected light, and a predetermined light source or optical filter is used under the conditions for observing the transmitted light. Unless it is, the latent image will not be visible. Therefore, a higher anti-counterfeit effect can be achieved.

  The optical filter may be a component of the labeled article 1. For example, the display body 10 may further include an optical filter that faces the front masking layer 11 with the regions 12a and 12b interposed therebetween. Alternatively, the part of the article 40 that faces the display body 10 may have a function as an optical filter. Also in this case, the latent image can be more reliably prevented from being visualized under conditions for observing the reflected light.

Next, the second aspect of the present invention will be described.
FIG. 9 is a plan view schematically showing a display body according to the second aspect of the present invention. FIG. 10 is a cross-sectional view of the display body shown in FIG. 9 taken along line XX.

  The display body 10 shown in FIGS. 9 and 10 is the same as the display body 10 described with reference to FIGS. 1 and 2 except that the following configuration is adopted.

That is, the display body 10 further includes a relief structure forming layer 15. The relief structure forming layer 15 faces the regions 12a and 12b with the front masking layer 11 interposed therebetween.
The relief structure forming layer 15 is light transmissive. The relief structure forming layer 15 is typically made of a transparent material, for example, a transparent resin.

  A relief structure is provided on the main surface of the relief structure forming layer 15 on the front surface hiding layer 11 side. This relief structure constitutes at least one of a diffraction grating, a hologram, and a light scattering structure. Here, as an example, the relief structure includes first and second relief structures constituting two diffraction gratings having different lattice constants and / or groove directions. The relief structure forming layer 15 can be omitted.

  As a material of the relief structure forming layer 15, for example, a thermoplastic resin, a thermosetting resin, or an ultraviolet ray or an electron beam curable resin is used. As the thermoplastic resin, for example, an acrylic resin, an epoxy resin, a cellulose resin, or a vinyl resin is used. As the thermosetting resin, for example, a urethane resin, a melamine resin, or a phenol resin that is crosslinked by adding polyisocyanate as a crosslinking agent to an acrylic polyol or polyester polyol having a reactive hydroxyl group is used. As the ultraviolet or electron beam curable resin, for example, epoxy acryl, epoxy methacryl, urethane acrylate or urethane methacrylate is used.

  The relief structure forming layer 15 can be formed, for example, by the following method. For example, an original plate provided with a relief structure is pressed against a thermoplastic resin layer while applying heat, and then the original plate is removed from the thermoplastic resin layer. Alternatively, a coating film made of an ultraviolet curable resin is formed, and the ultraviolet curable resin is cured by irradiating ultraviolet rays while pressing the original plate against the original, and then the original plate is removed from the coating film. Alternatively, a coating film made of a thermosetting resin is formed, and the thermosetting resin is cured by heating while pressing the original plate against the original, and then the original plate is removed from the coating film.

  The front masking layer 11 covers the surface of the relief structure forming layer 15 on which the relief structure is provided. In FIG. 10, in the front concealing layer 11, a first part corresponding to the first relief structure is denoted by reference numeral 11 a, and a second part corresponding to the second relief structure is denoted by reference numeral 11 b.

  Here, as an example, it is assumed that the region 12a is a gap or an opening provided in the region 12b, and the region 12b is a light shielding layer.

  In FIG. 9, the boundary between the display unit corresponding to the first portion 11a and the display unit corresponding to the second portion 11b is indicated by a one-dot chain line. As shown in FIG. 9, in this example, the display unit corresponding to the second portion 11b constitutes a pattern having a corolla shape.

  In FIG. 9, the boundary between the display unit corresponding to the region 12a and the display unit corresponding to the region 12b is indicated by a broken line. As shown in FIG. 9, in this example, the region 12c constitutes a pattern having a hollow star shape.

  The display body 10 is supported on an article, for example. When the display body 10 is supported on an article, for example, the same adhesive label as described with reference to FIG. 3 is used except that the structure described with reference to FIGS. 11 and 12 is employed. Alternatively, a transfer foil similar to that described with reference to FIG. 4 may be used except that the structure described with reference to FIGS. 11 and 12 is employed.

Next, an image displayed by the display body 10 will be described.
FIG. 11 is a plan view schematically showing an image displayed by the display when the labeled article including the display shown in FIGS. 9 and 10 is illuminated from the front side. FIG. 12 is a plan view schematically showing an image displayed by the display when the labeled article including the display shown in FIGS. 9 and 10 is illuminated from the back side.

  As shown in FIG. 11, when the display body 10 is illuminated from the front side, part of the illumination light is diffracted by the diffraction structure provided at the interface between the front cover layer 11 and the relief structure forming layer 15 of the display body 10. Is done. Accordingly, as is clear from the description with reference to FIG. 7, the observer observing the display 10 from the front side does not see a pattern having a hollow star shape, and has a condition that allows diffracted light to be perceived. Originally, a diffracted image including a pattern having a corolla shape can be seen, and the display body 10 looks like a mirror surface under conditions where diffracted light cannot be perceived.

  As shown in FIG. 12, when the display body 10 is illuminated from the back side with the article 40 interposed therebetween, as is clear from the description regarding FIG. 8, an observer observing the display body 10 from the front side Only the light transmitted through the regions 12a and 12b contributes to the display. As described above, here, the region 12a is a gap or an opening, and the region 12b is a light shielding layer, so that the display unit corresponding to the region 12a looks bright and the display unit corresponding to the region 12b looks dark. Accordingly, in this case, the display body 10 displays a pattern having a hollow star shape.

  Thus, the regions 12a and 12b form a latent image, and the latent image is visualized under special conditions. Since the regions 12a and 12b are concealed by the front concealment layer 11, the latent image is not visualized under normal observation conditions. Therefore, it is difficult to realize that the regions 12a and 12b form a latent image. Therefore, according to this technique, a high anti-counterfeit effect can be achieved.

  Further, the diffraction image displayed by the display 10 makes it difficult to realize that the front concealment layer 11 conceals the regions 12a and 12b. Therefore, the display body 10 that employs a configuration that displays a diffraction image can achieve a higher anti-counterfeit effect than a display body that does not employ this configuration.

  Here, a relief structure as a diffraction grating is provided on the surface of the front concealment layer 11, but a relief structure as a hologram or a light scattering structure may be provided on the surface of the front concealment layer 11. In this case, the same or similar effect as described above can be obtained.

  Alternatively, instead of providing a relief structure on the surface of the front masking layer 11, a volume hologram, a multilayer film, or a solidified cholesteric liquid crystal layer may be installed on the front side of the front masking layer 11. In this case, the same or similar effect as described above can be obtained.

Various modifications can be made to the display body 10.
FIG. 13 is a plan view schematically showing a modification of the display body shown in FIGS. FIG. 14 is a cross-sectional view taken along line XIV-XIV of the display shown in FIG.

  The display body 10 shown in FIGS. 13 and 14 is the same as the display body 10 described with reference to FIGS. 9 and 10 except that the following configuration is adopted.

  That is, the display body 10 further includes the base material 13 described with reference to FIG. The base material 13 can be omitted.

  The relief structure forming layer 15 is supported on the back surface of the substrate 13. A square-shaped opening is provided in the center of the relief structure forming layer 15. In addition, this opening is shown with the dashed-two dotted line in FIG.

  A relief structure constituting one diffraction grating is provided on the entire back surface of the relief structure forming layer 15. The front masking layer 11 covers only the back surface of the relief structure forming layer 15.

  The region 12 b is an L-shaped light shielding layer that covers approximately half of the back surface of the relief structure forming layer 15. The region 12a is an L-shaped region located on the back side of the portion of the relief structure forming layer 15 that is not covered with the region 12b. In FIG. 13, the boundary between the regions 12a and 12b is indicated by a broken line.

Next, an image displayed by the display body 10 will be described.
FIG. 15 is a plan view schematically showing an image displayed by the display when the labeled article including the display shown in FIGS. 13 and 14 is illuminated from the front side. FIG. 16 is a plan view schematically showing an image displayed by the display when the labeled article including the display shown in FIGS. 13 and 14 is illuminated from the back side.

  As shown in FIG. 15, when the display body 10 is illuminated from the front side, an observer observing the display body 10 from the front side cannot see the pattern having the L shape. In this case, an observer who is observing the display body 10 from the front side can see a diffraction image having a frame shape under conditions where the diffracted light can be perceived, and the diffracted light cannot be perceived. Under such conditions, the display 10 looks like a mirror surface provided with a rectangular window.

  As shown in FIG. 16, when the display body 10 is illuminated from the back side with the article 40 and the adhesive or adhesive layer 20 sandwiched therebetween, a region 12a is shown to an observer observing the display body 10 from the front side. The display unit corresponding to the area 12 appears bright, and the display unit corresponding to the region 12b appears dark. Accordingly, in this case, the display body 10 displays a frame-shaped pattern composed of a brighter L-shaped pattern and a darker L-shaped pattern.

  As described above, the regions 12 a and 12 b and the front cover layer 11 may not be provided over the entire display body 10.

Next, the third aspect of the present invention will be described.
FIG. 17 is a plan view schematically showing a display body according to the third aspect of the present invention. 18 is a cross-sectional view taken along line XVIII-XVIII of the display shown in FIG.

  The display body 10 shown in FIGS. 17 and 18 is the same as the display body 10 described with reference to FIGS. 9 and 10 except that the following configuration is adopted.

  That is, in the display body 10, the relief structure forming layer 15 is located on the back side of the front hiding layer 11. A relief structure similar to that described with reference to FIGS. 9 and 10 is provided on the front surface of the relief structure forming layer 15.

  The front masking layer 11 covers the front surface of the relief structure forming layer 15. A relief structure similar to that provided on the front surface of the relief structure forming layer 15 is provided on the front surface of the front masking layer 11.

Further, the display body 10 further includes an intermediate layer 17 and a protective layer 19.
The intermediate layer 17 is interposed between the relief structure forming layer 15 and the regions 12a and 12b. The intermediate layer 17 serves to flatten the uneven surface formed by the regions 12a and 12b, for example. The intermediate layer 17 can be omitted.

  The intermediate layer 17 is light transmissive. The intermediate layer 17 may have light scattering properties, but is typically transparent. The intermediate layer 17 is made of, for example, a transparent resin. As the material of the intermediate layer 17, for example, a polymer resin such as a polyester resin, an acrylic resin, a butyral resin, and a vinyl chloride resin, or a monomer or oligomer that can be cured with ultraviolet rays is used. This material may further contain additives such as an ultraviolet absorber, a photopolymerization initiator, an antifoaming agent, a leveling agent, and an antiblocking agent. For example, the intermediate layer 17 is obtained by dissolving this material in an organic solvent as necessary, and applying this on a base by a coating method such as a gravure method, a micro gravure method, a comma coater method, and a die coater method. Obtained by drying.

  The protective layer 19 covers the front surface of the front hiding layer 11. The protective layer 19 serves to protect the front cover layer 11 and the like from damage and deterioration. The protective layer 19 is light transmissive. The protective layer 19 may have light scattering properties, but is typically transparent. The protective layer 19 is made of, for example, a transparent resin. The protective layer 19 can be omitted.

  The regions 12a and 12b have different optical anisotropies. For example, at least one of the regions 12a and 12b has birefringence, and the birefringence is different from each other. Alternatively, at least one of the regions 12a and 12b functions as a polarizer, and the functions as the polarizer are different from each other.

  For example, the regions 12a and 12b are birefringent layers that each include a slow axis and a fast axis in the in-plane direction, and at least one of the slow axis direction and the retardation is different from each other. Alternatively, one of the regions 12a and 12b is a birefringent layer in which one is optically isotropic and the other includes a slow axis and a fast axis in the in-plane direction. Alternatively, each of the regions 12a and 12b is a birefringent layer that selectively reflects right or left circularly polarized light having a specific wavelength, and at least one of the wavelength, intensity, and rotation direction of the electric field vector of the selectively reflected circularly polarized light. is there. Alternatively, the regions 12a and 12b are birefringent layers in which one is optically isotropic and the other selectively reflects right or left circularly polarized light having a specific wavelength.

  Alternatively, the regions 12a and 12b are, for example, two selected from the group consisting of a linear polarizer, an elliptical polarizer, and a circular polarizer. Alternatively, the regions 12a and 12b are linear polarizers having different transmission axis directions. Alternatively, the regions 12a and 12b are circular polarizers having different rotation directions of the electric field vector of the circularly polarized light to be transmitted. Alternatively, the regions 12a and 12b are elliptical polarizers in which at least one of the ratio of the major axis to the minor axis of the ellipse, the direction of the major axis, and the rotation direction of the electric field vector of the elliptically polarized light to be transmitted is different.

  Here, as an example, each of the regions 12a and 12b is a birefringent layer that includes a slow axis and a fast axis in the in-plane direction, that is, a retardation layer, and the retardation is equal to each other. The directions are different from each other.

  In the display body 10, the polarizer 16, the retardation layer 18, and the intermediate layer 17 constitute regions 12 a and 12 b. Specifically, a portion 16a of the polarizer 16 that does not face the retardation layer 18 and a portion 17a of the intermediate layer 17 that does not face the retardation layer 18 constitute a region 12a. And the laminated body of the phase difference layer 18, the part 16b which faced the phase difference layer 18 among the polarizers 16, and the part 17b which faced the phase difference layer 18 among the intermediate | middle layers 17 comprised the area | region 12b. Yes.

  The polarizer 16 has, for example, a layer shape, and faces the front masking layer 11 with the intermediate layer 17 and the relief structure forming layer 15 interposed therebetween. The polarizer 16 may be any of a linear polarizer, a circular polarizer, and an elliptical polarizer. The polarizer 16 may be either an absorption polarizer or a scattering polarizer. Examples of the absorption linear polarizer include, for example, a PVA-iodine polarizer in which a polyvinyl alcohol (PVA) stretched film absorbs iodine, a dichroic dye polarizer, a metal or metal compound-containing polarizer, or a polyene A polymer polycrystalline polarizer such as a mold is used. Here, as an example, it is assumed that the polarizer 16 is an absorptive linear polarizer.

  The retardation layer 18 is interposed between the polarizer 16 and the intermediate layer 17. The retardation layer 18 faces a part of the polarizer 16 and has a shape corresponding to the character string “TP” here. Typically, the retardation layer 18 has approximately the same transmittance as the intermediate layer 17. Here, as an example, the retardation layer 18 and the intermediate layer 17 exhibit substantially the same transmission spectrum when illuminated with white light.

  The retardation layer 18 is, for example, a fixed liquid crystal layer formed by fixing a liquid crystal material. As this liquid crystal material, for example, a smectic liquid crystal material or a nematic liquid crystal material having the properties of a thermotropic liquid crystal is used. Typically, a crosslinkable and / or polymerizable liquid crystal material is used.

  As the crosslinkable and / or polymerizable liquid crystal material, for example, a liquid crystal material in which a functional group such as an acrylic group is introduced at the end of a liquid crystal molecule is used. Such a liquid crystal material can be polymerized and / or crosslinked by irradiating active energy rays in the presence of an initiator.

  As the liquid crystal material that can be polymerized and / or crosslinked, for example, a material containing a monomer or oligomer having two or more energy ray-curable groups in the molecule is used. As such a liquid crystal material, for example, a radical polymerizable monomer or oligomer is used. For example, polyfunctional monomers such as trimethylolpropane triacrylate, 1,6-hexanediol diacrylate, pentaerythritol tetraacrylate, pentaerythritol triacrylate and dipentaerythritol hexaacrylate, or polyurethane polyacrylate, epoxy resin polyacrylate And multifunctional oligomers such as acrylic polyol polyacrylates.

  The radical polymerizable monomer or oligomer may further contain a monofunctional monomer in addition to the polyfunctional monomer or oligomer. Examples of the monofunctional monomer include alkyl (C1 to C18) acrylate, alkyl (C1 to C18) methacrylate, benzyl acrylate, benzyl methacrylate, cyclohexyl acrylate, cyclohexyl methacrylate, alkylene (C2 to C4) glycol acrylate, and alkylene (C2 to C2). C4) glycol methacrylate, alkoxy (C1-C10) alkyl (C2-C4) acrylate, alkoxy (C1-C10) alkyl (C2-C4) methacrylate, polyalkylene (C2-C4) glycol acrylate, polyalkylene (C2-C4) Glycol methacrylate, alkoxy (C2-C10) polyalkylene (C2-C4) glycol acrylate, or alkoxy (C2-C10) polyalkylene (C2-C4) using a glycol methacrylate. In addition, “Cm to Cn” written in parentheses after the functional name indicates that the number of carbon atoms contained in the functional group is in the range of m to n.

  Cationic polymerizable monomers or oligomers may be used as liquid crystal materials that can be polymerized and / or crosslinked. As the cationic polymerizable monomer or oligomer, for example, an aromatic epoxy compound, an alicyclic epoxy compound, or a glycidyl ester compound is used.

  Initiators for radical polymerization include, for example, α-hydroxyacetophenone-based, α-aminoacetophenone-based acetophenone-based, benzoin ether-based, benzyl ketal-based, α-dicarbonyl-based, or α-acyloxime ester-based initiators. Use the agent. For example, α-aminoacetophenone, acetophenone diethyl ketal, benzyldimethyl ketal, α-hydroxycyclohexyl phenyl ketone, 2-hydroxy-2-methylphenylpropanone, benzophenone, Michler's ketone, isopropylthioxanthone, or a combination of benzophenone and N-methyldiethanolamine Is used.

  As the initiator for cationic polymerization, for example, a compound generally used for this purpose, or a mixture of such a compound and a sensitizer or a peroxide is used. For example, an allyl iodonium salt-α-hydroxyacetophenone-based, triallylsulfonium salt-based, metallocene compound-peroxide combined system, metallocene compound-thioxanthone combined system, or metallocene compound-anthracene combined initiator is used.

For example, the fixed liquid crystal layer is formed by the following method.
First, an alignment process is performed on the base surface on which the solidified liquid crystal layer is to be formed. For example, a rubbing process is performed in which the base surface is rubbed with a rubbing cloth. As the rubbing cloth, for example, cotton or velvet is used.

  An alignment film may be formed on the ground. For example, a coating liquid containing a resin such as PVA and polyimide is applied on the base, and this coating film is dried. For this application, for example, a method using a wire bar, a gravure method, or a micro gravure method is used. The coating film is formed so that the thickness after drying is, for example, 0.1 μm to 20 μm, typically 0.3 μm to 10 μm. Next, the coating film is subjected to a rubbing treatment. Thereby, an alignment film is obtained.

  The alignment film may be formed using another alignment technique such as a photo-alignment technique. Further, the alignment treatment and the formation of the alignment film on the base surface may be omitted.

  Next, a liquid crystal composition containing a crosslinkable and / or polymerizable liquid crystal material, an initiator, and optionally a solvent is applied on the base or alignment film. After the coating film is dried, the coating film is subjected to pattern exposure. For example, this coating film is irradiated with ultraviolet rays through a mask. Alternatively, this film is drawn with an electron beam. This causes cross-linking and / or polymerization of the liquid crystal material at the exposed portion of the coating film.

  Thereafter, the coating film is subjected to a development treatment to remove unexposed portions from the coating film. As described above, a solidified liquid crystal layer is obtained.

  The solidified liquid crystal layer may be formed using a printing method such as a gravure printing method instead of using photolithography. For example, the liquid crystal material heated to the glass transition temperature or higher may be printed, and the liquid crystal material may be fixed by cooling it. However, when the liquid crystal material is crosslinked or polymerized, a higher physical strength can be achieved as compared with the case where the liquid crystal material is not crosslinked or polymerized.

  A layer other than the solidified liquid crystal layer may be used as the retardation layer 18. For example, a uniaxially stretched polymer film can be used as the retardation layer 18. As a material for the polymer film, for example, polycarbonate or polyolefin can be used. Alternatively, cellophane may be used as the retardation layer 18.

  When such a film is used as the retardation layer 18, for example, a film cut into a predetermined shape is prepared, and this is attached onto the polarizer 16. Or the film as a continuous film is affixed on the polarizer 16, and an unnecessary part is removed from this film after that. In this way, the retardation layer 18 is obtained.

  The slow axis of the retardation layer 18 intersects the transmission axis of the polarizer 16. For example, the angle formed by the slow axis of the retardation layer 18 and the transmission axis of the polarizer 16 is about 45 °. When the wavelength of one component of light that should be perceived by the observer when the latent image is visualized is λ, the retardation of the retardation layer 18 with respect to the light with the wavelength λ is, for example, about λ / 4. Alternatively, the retardation of the retardation layer 18 with respect to light having the wavelength λ is set to about λ / 2, for example. Here, as an example, the slow axis of the retardation layer 18 and the transmission axis of the polarizer 16 form an angle of 45 °, and the retardation of the retardation layer 18 is λ / 2.

  The display body 10 is supported on an article, for example. When the display body 10 is supported on an article, for example, the same adhesive label as described with reference to FIG. 3 is used except that the structure described with reference to FIGS. 17 and 18 is employed. Alternatively, a transfer foil similar to that described with reference to FIG. 4 may be used except that the structure described with reference to FIGS. 17 and 18 is employed.

Next, an image displayed when the display body 10 is observed with the naked eye will be described.
FIG. 19 is a plan view schematically showing an image displayed by the display when the labeled article including the display shown in FIGS. 17 and 18 is illuminated from the front side. FIG. 20 is a plan view schematically showing an image displayed on the display body when the labeled article including the display body shown in FIGS. 17 and 18 is illuminated from the back side.

  As shown in FIG. 19, when the display body 10 is illuminated from the front side, part of the illumination light is diffracted by the diffraction structure provided at the interface between the front hiding layer 11 and the protective layer 19 of the display body 10. . Accordingly, similarly to the case described with reference to FIG. 11, the observer observing the display body 10 from the front side does not see a pattern having a hollow star shape, and has a condition that allows diffracted light to be perceived. Originally, a diffracted image including a pattern having a corolla shape can be seen, and the display body 10 looks like a mirror surface under conditions where diffracted light cannot be perceived.

  As shown in FIG. 20, when the display body 10 is illuminated from the back side with the article 40 interposed therebetween, the illumination light transmitted through the article 40 is incident on the polarizer 16. The polarizer 16 absorbs linearly polarized light whose electric field vector oscillation direction is parallel to the absorption axis, and transmits linearly polarized light whose electric field vector oscillation direction is parallel to the transmission axis.

  The linearly polarized light transmitted by the first portion 16a of the polarizer 16 is transmitted through the portion 17a of the intermediate layer 17 and the relief structure forming layer 15 in this order without rotating the vibration direction of the electric field vector, and the front concealing layer. 11 is incident. The front masking layer 11 transmits only a part of the linearly polarized light from the first portion 16a without rotating the vibration direction of the electric field vector. The linearly polarized light from the first portion 16a that has passed through the front hiding layer 11 passes through the protective layer 19 without rotating the vibration direction of the electric field vector, and is perceived by the observer.

  On the other hand, the linearly polarized light transmitted by the second portion 16 b of the polarizer 16 is incident on the retardation layer 18. The linearly polarized light is transmitted through the phase difference layer 18, and the vibration direction of the electric field vector is rotated by 90 °. The linearly polarized light transmitted through the phase difference layer 18 is transmitted through the other part 17b of the intermediate layer 17 and the relief structure forming layer 15 in this order without rotating the oscillation direction of the electric field vector, and enters the front concealment layer 11. Incident. The front masking layer 11 transmits only a part of the linearly polarized light from the second portion 16b without rotating the vibration direction of the electric field vector. The linearly polarized light from the second portion 16b that has passed through the front hiding layer 11 passes through the protective layer 19 without rotating the vibration direction of the electric field vector, and is perceived by the observer.

As is clear from the description related to FIG. 8, as described above, only the light transmitted through the regions 12a and 12b contributes to the display for the observer observing the display body 10 from the front side. As described above, since the retardation layer 18 and the intermediate layer 17 exhibit substantially the same transmission spectrum when illuminated with white light, the spectrum of the display light from the region 12a and the spectrum of the display light from the region 12b are substantially equal. . The display light from the region 12a and the display light from the region 12b differ in the direction of vibration of the electric field vector by 90 °, but such a difference cannot be perceived by the observer. Therefore, the display unit corresponding to the region 12a and the display unit corresponding to the region 12b look the same color. That is, in this case, the display body 10 does not display a pattern corresponding to each of the regions 12a and 12b.
Thus, the display body 10 looks like a general OVD when observed with the naked eye.

  Next, an image displayed when the display 10 is illuminated from the back side and observed through a polarizer will be described.

  FIG. 21 shows an example of an image displayed by the display when a polarizer is installed on the front side of the labeled article including the display shown in FIGS. 17 and 18 and the labeled article is illuminated from the back. It is a top view shown roughly. FIG. 22 shows another image displayed by the display when a polarizer is installed on the front side of the labeled article including the display shown in FIGS. 17 and 18 and the labeled article is illuminated from the back. It is a top view which shows an example roughly.

21 and 22, reference numeral 60 indicates a polarizer.
The polarizer 60 may be a linear polarizer, a circular polarizer, or an elliptical polarizer. For example, when the regions 12 a and 12 b emit linearly polarized light having different electric field vector oscillation directions, a linear polarizer or an elliptical polarizer is used as the polarizer 60. Alternatively, when the region 12a emits one of right circularly polarized light and left circularly polarized light and the region 12a emits the other of right circularly polarized light and left circularly polarized light, a circular polarizer or an elliptical polarizer is used as the polarizer 60. .

  Further, the polarizer 60 may be either an absorption type polarizer or a scattering type polarizer. As an absorption type linear polarizer, for example, a PVA-iodine polarizer in which iodine is absorbed in a PVA stretched film, a dichroic dye polarizer, a metal or metal compound-containing polarizer, or a polyene type A molecular polycrystalline polarizer is used. Here, as an example, it is assumed that the polarizer 60 is an absorptive linear polarizer.

  FIGS. 21 and 22 illustrate a state in which the polarizer 60 is installed between the labeled article 1 and the observer under the observation conditions described with reference to FIG.

  When the light source 50, the labeled article 1 and the polarizer 60 are arranged in this way, the transmission axis of the polarizer 60 is parallel to the vibration direction of the electric field vector of linearly polarized light emitted from the display unit corresponding to the region 12b. Then, the linearly polarized light from the region 12 a is absorbed by the polarizer 60, and the linearly polarized light from the region 12 b passes through the polarizer 60. Therefore, as shown in FIG. 21, the display unit corresponding to the region 12a on the display surface appears dark, and the display unit corresponding to the region 12b on the display surface appears bright. Therefore, the display body 10 displays the character string “TP”.

  On the other hand, when the transmission axis of the polarizer 60 is parallel to the vibration direction of the electric field vector of the linearly polarized light emitted from the display unit corresponding to the region 12a, the linearly polarized light from the region 12a is transmitted through the polarizer 60, Linearly polarized light from 12b is absorbed by the polarizer 60. Therefore, as shown in FIG. 22, the display unit corresponding to the region 12a on the display surface looks bright, and the display unit corresponding to the region 12b on the display surface looks dark. Therefore, the display body 10 displays the character string “TP”.

  As described above, the regions 12a and 12b form a latent image, and the latent image is visualized by illuminating the display body 10 from the back side and observing the display body 10 from the front side through the polarizer 60. The regions 12a and 12b are not or difficult to distinguish from each other without the front concealing layer 11, and are also concealed by the front concealing layer 11, so that the latent image can be obtained under normal observation conditions. There is no visualization. Therefore, it is difficult to realize that the regions 12a and 12b form a latent image. Therefore, according to this technique, a high anti-counterfeit effect can be achieved.

  Further, the diffraction image displayed by the display 10 makes it difficult to realize that the front concealment layer 11 conceals the regions 12a and 12b. Therefore, the display body 10 that employs a configuration that displays a diffraction image can achieve a higher anti-counterfeit effect than a display body that does not employ this configuration.

  Here, a relief structure as a diffraction grating is provided on the surface of the front concealment layer 11, but a relief structure as a hologram or a light scattering structure may be provided on the surface of the front concealment layer 11. In this case, the same or similar effect as described above can be obtained.

  The relief structure provided on the surface of the front hiding layer 11 may be omitted. In this case, the effect derived from the relief structure cannot be obtained, but other effects can be obtained.

  Instead of providing a relief structure on the surface of the front concealment layer 11, a volume hologram, a multilayer film, or a solidified cholesteric liquid crystal layer may be disposed on the front side of the front concealment layer 11. In this case, the same or similar effect as described above can be obtained.

Various modifications can be made to the display body 10.
FIG. 23 is a cross-sectional view schematically showing a modification of the display body shown in FIGS. The display body 10 shown in FIG. 23 is the same as the display body 10 described with reference to FIGS. 17 and 18 except that the base body 13 is included instead of the polarizer 16. That is, in this display body 10, a portion 17a of the intermediate layer 17 that does not face the retardation layer 18 forms a region 12a. And the laminated body of the phase difference layer 18 and the part 17b which faced the phase difference layer 18 among the intermediate | middle layers 17 comprises the area | region 12b.

  When viewed with the naked eye, the display 10 displays an image similar to that described with reference to FIGS. 19 and 20. The display body 10 illuminates with polarized light such as linearly polarized light from the back side and displays the same image as described with reference to FIGS. 21 and 22 when observed through the polarizer 60. To do.

  FIG. 24 is a cross-sectional view schematically showing another modification of the display body shown in FIGS. 17 and 18. The display body 10 shown in FIG. 24 is the same as the display body 10 described with reference to FIG. 23 except that the following configuration is adopted.

  That is, in the display body 10, the retardation layer 18 is a continuous film. The retardation layer 18 is provided on the entire surface of the base material 13, for example.

  The retardation layer 18 includes regions 18a and 18b. For example, each of the regions 18a and 18b has birefringence, and the directions of the slow axes are different from each other. Alternatively, the regions 18a and 18b each have birefringence, the directions of the slow axes are the same, and the retardations are different from each other. Alternatively, one of the regions 18a and 18b has birefringence, and the other of the regions 18a and 18b is optically isotropic. Here, as an example, regions 18a and 18b are each birefringent, their slow axes are orthogonal to each other, and their respective retardations are λ / 4. And

  The regions 18a and 18b have shapes corresponding to the regions 12a and 12b of the display body shown in FIG. The laminate of the region 18a and the portion 17a constitutes the region 12a, and the laminate of the region 18b and the portion 17b constitutes the region 12b.

  As the retardation layer 18, for example, a fixed liquid crystal layer similar to that described with respect to the display 10 shown in FIGS. 17 and 18 can be used. In this case, for example, first, a base including a plurality of regions for aligning mesogens in different directions is prepared. For example, these regions are rubbed in different directions using a mask. Alternatively, these regions are formed using a photo-alignment technique. Next, a fixed liquid crystal layer is formed on the base by the same method as described for the display 10 shown in FIGS. Thus, an immobilized liquid crystal layer including a plurality of regions having different mesogen orientation directions can be obtained.

  When viewed with the naked eye, the display 10 displays an image similar to that described with reference to FIGS. 19 and 20. And this display body 10 illuminates, for example, with linearly polarized light in which the vibration direction of the electric field vector forms an angle of + 45 ° and −45 ° with respect to the slow axis of the regions 18a and 18b from the back side, When observed through a polarizer 60 as a right or left circular polarizer, an image similar to that described with reference to FIG. 21 or an image similar to that described with reference to FIG. 22 is displayed. .

  FIG. 25 is a cross-sectional view schematically showing still another modification of the display body shown in FIGS. 17 and 18. The display body 10 shown in FIG. 24 is the same as the display body 10 described with reference to FIG. 23 except that the following configuration is adopted.

  That is, the display body 10 includes the polarizing layer 16 instead of the retardation layer 18. The polarizing layer 16 includes regions 16a and 16b.

  For example, each of the regions 16a and 16b functions as a polarizer, and the directions of the transmission axes are different from each other. Alternatively, one of the regions 16a and 16b functions as a polarizer, and the other of the regions 16a and 16b has optical absorptivity and optical transparency and is optically isotropic. Here, as an example, it is assumed that the regions 16a and 16b each function as an absorption linear polarizer, and the directions of their transmission axes are orthogonal to each other.

  As this polarizing layer 16, what added the dichroic dye to the fixed liquid crystal layer demonstrated regarding the display body 10 shown in FIG. 24, for example can be used. The absorption axis of the dichroic dye is almost equal to the orientation direction of the mesogen. Therefore, the polarizing layer 16 including the regions 16a and 16b having different transmission axis directions can be obtained by the same method except that the dichroic dye is added.

  As the dichroic dye, for example, an azo, anthraquinone, quinoline or pyrazolone dye compound is used. For example, C.I. I. Direct Blue 67, C.I. I. Direct Green 59, C.I. I. Direct Violet 48, or C.I. I. Direct Red 39 is used.

  When viewed with the naked eye, the display 10 displays an image similar to that described with reference to FIGS. 19 and 20. And when this display body 10 is illuminated with natural light from the back side and observed through the polarizer 60 as a linear polarizer or an elliptical polarizer, for example, it is the same as described with reference to FIG. Or an image similar to that described with reference to FIG.

  When the display 10 described with reference to FIGS. 1 to 25 further includes a back masking layer, the surface of the back masking layer may be a mirror surface, and at least one of a diffraction grating, a hologram, and a light scattering structure. The relief structure which comprises one may be provided. When providing a relief structure in both the front hiding layer and the back hiding layer, the relief structures may be the same or different.

  When the article to support the display body 10 includes a transparent portion at the position to support the display body 10, instead of providing a back masking layer on the display body 10, a back masking layer is provided on the previous article. Also good. For example, the back masking layer may be provided between the transparent part of the article and the display body 10. Or you may provide a back surface concealment layer so that it may face the display body 10 on both sides of the transparent part of articles | goods.

  In these display bodies 10, the regions 12a and 12b show different transmittances when irradiated with polarized light having any wavelength in the visible light region as illumination light, or use different polarized light as transmitted light. Eject. When these display bodies 10 irradiate with polarized light having any wavelength in the visible light region as illumination light, they show different transmittances from the regions 12a and 12b or different from the regions 12a and 12b. One or more regions that emit polarized light as transmitted light may be further included.

  Each component of the display body 10 may be colored as long as the function is not impaired. In addition, the display body 10 may further include a print pattern on the surface or between the layers. When such a configuration is adopted, for example, design properties can be improved.

  The display body 10 may further include other layers. For example, the display body 10 may further include an adhesion anchor layer in order to increase the interlayer adhesion strength.

As the first and second relief structures, diffraction gratings in which the length directions of the grooves are orthogonal to each other are formed. The contours of these relief structures are corolla shapes.

  Next, the front concealment layer 11 was formed on the relief structure forming layer 15 by vacuum vapor deposition. As the front masking layer 11, an aluminum layer having a thickness of 0.03 μm was formed.

  Subsequently, regions 12a and 12b were formed on the front concealing layer 11 by using a gravure printing method. For this printing, black ink obtained by adding carbon black to acrylic resin was used. As the region 12b, a black pattern having a thickness of 2 μm was formed, which was composed of a portion having a star shape and a portion surrounding them with a gap. And the gap of this black pattern was made into field 12b.

  Next, using the display body 10 thus obtained, an adhesive label with a mount similar to that described with reference to FIG. 3 was manufactured.

  Then, the labeled article 1 shown in FIGS. 11 and 12 was manufactured using the adhesive label with the mount. That is, the pressure-sensitive adhesive label 2 was peeled off from the support 30 a and attached to the article 40. As the article 40, a gift certificate having a printing pattern on paper was used. In addition, the part which should affix the adhesive label 2 of this gift certificate was opaque and had a light transmittance.
