Description

  The present invention relates to a display body and printed matter that suppress counterfeiting or counterfeiting in certified articles, securities, and the like.

  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 hologram that is difficult to counterfeit or counterfeit and is easy to distinguish from counterfeit or counterfeit is attached to such articles in order to suppress counterfeiting or counterfeiting.

  Holograms have an excellent design and have been used in many ways due to the difficulty of forgery and alteration that cannot be duplicated even on color copiers. However, in recent years, sophisticated counterfeit products have appeared in holograms, and there are cases in which it is difficult to determine authenticity at first glance.

  Therefore, various proposals using the light scattering effect have been made in order to differentiate from the hologram having the effect of shining in seven colors. For example, Patent Document 1 describes a true / false determination object that can determine authenticity by forming a light scattering layer on the side surface of a microprism and changing the observation surface.

  Patent Document 2 describes a forgery prevention medium characterized in that light is scattered by providing fine holes in a transparent substrate.

  Further, Patent Document 3 describes a display body that emits white diffracted light by combining white light emitted from a light scattering structure and diffraction gratings having different spatial frequencies.

  However, Patent Document 1 has a complicated structure such as forming a large number of microprisms and providing a light scattering layer only on one surface of the prism surface, which complicates the actual manufacturing process and increases the cost. It is thought that it will end.

  In Patent Document 2, it is said that the anti-counterfeit determination is performed by applying a transparent liquid such as water to the fine holes and eliminating the light scattering property, and the easy anti-counterfeit determination is realized. Is hard to say.

  In Patent Document 3, white expression is performed using a combination of diffraction gratings. However, the repetitive pattern of the diffraction gratings influences, and the emission range of white diffracted light is narrow. For this reason, there is a problem that perceiving a color other than white when observing at a tilt impairs the design.

Japanese Patent No. 4508563 JP 2004-340992 A JP 2008-83599 A

  The invention according to claim 9 is a printed matter comprising the display body according to any one of claims 1 to 8 and a base material on which printing is performed to support the display body.

  According to the present invention, by providing a display structure comprising a relief structure molding layer having a directional scattering region, a transparent light reflection layer disposed on the surface thereof, and a printed layer composed of a light and shade pattern, In the angle range where the directional scattering region emits scattered light, the characters, symbols, marks, etc. of the printed layer cannot be observed, and the gray pattern is only outside the angle range where the finger scattered light is emitted. A display body that can be observed as a latent image is realized.

  Furthermore, since the directional scattering region of the relief structure forming layer has a function of emitting scattered light only in a predetermined angle range, it is possible to emit light having strong scattered light intensity. Therefore, the directional scattering region can confirm brighter scattered light compared to normal scattered light under a fixed illumination light source, and has the effect of forming characters, symbols, marks, etc. on the printed layer as latent images. It becomes possible to raise.

  In addition, by providing a transparent light reflecting layer on the surface of the directional scattering region, outside the angle range where the scattered light is emitted, characters, symbols, and patterns of the printed layer disposed below the printed light layer Can be observed.

  Furthermore, the directional scattering region is formed with a fine structure on the order of several nanometers, and special equipment is required for counterfeiting and imitation, making it extremely difficult to duplicate the structure and displaying with high security. The body.

  Further, the directional scattering region of the relief structure and the shading pattern of the printed layer form different characters, symbols, marks, etc., and the size thereof is about 2 mm or less, thereby forming the directional scattering region. When the mark or the like and the mark or the like formed by the shading pattern are combined, the marks can be mixed in a fine size. As a result, the pattern that can be observed becomes complicated, and it becomes difficult to distinguish the boundary between the directional scattering region and the printing layer region, and an improvement in security can be expected.

  It is also possible for the light scattering axes of the directional scattering regions to be orthogonal to each other. By doing so, it is possible to display different images for each directional scattering region, which further improves design and security. Is possible.

  Hereinafter, preferred embodiments of the present invention will be described. The embodiments described below are preferred specific examples of the present invention, and various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise described, the present invention is not limited to these forms.

  FIG. 1 is a cross-sectional view showing a configuration example of a display body 10 according to the present embodiment, and FIGS. 2 and 3 are views showing an example of how the display body 10 is seen.

  As shown in FIG. 1, the display 10 according to the present embodiment includes a relief structure molding layer 2 including a directional scattering region 3 on at least one surface of a light-transmitting substrate 1, and the relief structure molding layer 2 is provided with a transparent light reflecting layer 4 on the surface 2 and a printed layer 5 on which a light and shade pattern 11 such as letters, symbols and marks is formed on the surface far from the observation direction of the light transmissive substrate 1. Provided. The directional scattering region 3 has a function of strongly emitting scattered light only in a predetermined angle range.

  As described above, the printed layer 5 is formed on the surface far from the observation direction of the light-transmitting substrate 1 by the combination of the shading pattern 11 arranged in the printed layer 5 and the directional scattering region 3 provided in the relief structure forming layer 2. The image to be displayed is determined by the latent image defined by the light and shade pattern 11 formed on and the scattered light defined by the pattern 12 formed by the directional scattering region 3.

  As the light-transmitting substrate 1, a film or sheet made of a resin having optical transparency such as polyethylene terephthalate (PET), polycarbonate (PC), and triacetyl cellulose (TAC) is preferable. As a material of the light transmissive substrate 1, an inorganic material such as glass may be used.

  Moreover, the light transmissive substrate 1 may have a single layer structure or a multilayer structure. Furthermore, treatments such as antireflection treatment, low antireflection treatment, hard coat treatment, antistatic treatment, and antifouling treatment may be performed.

  As a material of the relief structure molding layer 2, a resin having optical transparency can be used. For example, when a thermoplastic resin, a thermosetting resin, or a photocurable resin is used, the relief structure molding layer 2 having the directional scattering region 3 on one surface can be easily formed by transfer using the original plate. . Moreover, the material of the light transmissive base material 1 and the relief structure molding layer 2 may be the same or different.

  The transparent light reflecting layer 4 has a role of increasing the reflectance of the interface where the relief structure molding layer 2 is provided. Examples of the material include zinc sulfide (ZnS), indium oxide (ITO), and zinc oxide (ZnO). Such materials can be used. The material of the transparent light reflecting layer 4 may be a transparent material having a refractive index different from that of the relief structure molding layer 2 such as a dielectric material. The transparent light reflecting layer 4 is not limited to a single layer, and may be a multilayer film.

  The transparent light reflecting layer 4 can be formed by a thin film forming technique such as vapor deposition or sputtering. Furthermore, a pattern can also be expressed using the distribution of the transparent light reflecting layer 4 by spatially distributing the region where the transparent light reflecting layer 4 exists.

  The printing layer 5 displays images such as pictures, characters, symbols, and various inks such as offset ink, letterpress ink, and gravure ink can be used depending on the printing method of the printing layer 5. Inks used for printing can be classified by composition such as resin type ink, oil-based ink, water-based ink, etc., and classification by drying method such as oxidation polymerization type ink, osmotic drying type ink, evaporation drying type ink, ultraviolet curing type ink, It is appropriately selected according to the type of substrate and the printing method. Also, a technology for forming the printing layer 5 by transferring to a substrate such as paper using static electricity of toner in which colored particles such as graphite and pigment are attached to charged plastic particles, and then fixing by heating. Is also common.

  Further, the ink used for the printing layer 5 may be a functional ink that varies in color depending on the observation angle. By using the functional ink, the gray pattern 11 formed on the printing layer 5 as a latent image can be observed. Further, it is possible to observe different colors by slightly changing the observation angle, and it is possible to further improve security and design.

  Furthermore, the size of the shading pattern 11 formed on the printing layer 5 is preferably 2 mm or less. An image formed by the shading pattern 11 formed on the printed layer 5 when the display body 10 is observed by setting the size of the pattern 12 formed by the directional scattering region 3 to be 2 mm or less, which will be described later, Images formed by the directional scattering region 3 can be appropriately mixed, and an observation image without a sense of incongruity can be obtained.

  If the size of the pattern 12 is 2 mm or less, the effect of concealing the light and shade pattern 11 formed on the printing layer 5 as a latent image can be improved. Moreover, even if the shading pattern 11 of the printing layer 5 is 2 mm or more in size, it may be the same as the pattern 12 formed by the directional scattering region 3, and the ratio of the sizes is about 0.8 to 0.8. 1.2 is preferred. Within that range, there is no sense of incongruity even if the image formed by the directional scattering region 3 and the image formed by the light and shade pattern 11 formed on the print layer 5 are mixed, and the light and shade pattern 11 formed on the print layer 5 is not present. It is possible to fully exhibit the concealing effect.

  The display body 10 may be provided with an adhesive layer (adhesive layer) on the surface of the print layer 5 opposite to the surface in contact with the light transmissive substrate 1. When the adhesive layer is provided, it can be easily affixed to a security label as a security label.

  Next, the directional scattering region 3 will be described in detail.

  FIG. 4 is a plan view schematically showing an example of the directional scattering region 3. The directional scattering region 3 shown in FIG. 4 includes a plurality of directional scattering structures 14. Each of these directional scattering structures 14 is a plurality of convex portions and / or concave portions that are linear and have the same direction in the directional scattering region 3. That is, in the directional scattering region 3, the directional scattering structures 14 are arranged almost in parallel.

  In the directional scattering region 3, the directional scattering structures 14 may not be arranged completely in parallel. As long as the directional scattering region 3 has sufficient light scattering ability anisotropy, in the directional scattering region 3, for example, the longitudinal direction of some directional scattering structures 14 and some other directivities. The longitudinal direction of the scattering structure 14 may intersect. Hereinafter, of the directions parallel to the main surface of the directional scattering region 3, the direction in which the directional scattering region 3 exhibits the minimum light scattering ability is referred to as “orientation direction”, and the directional scattering region 3 has the maximum light scattering ability. The direction indicating is called “light scattering axis”.

  In the directional scattering region 3 shown in FIG. 4, the direction indicated by the arrow 9b is the orientation direction, and the direction indicated by the arrow 9a is the light scattering axis. For example, when the directional scattering region 3 is illuminated from an oblique direction perpendicular to the orientation direction 9b and the directional scattering region 3 is observed from the front, the directional scattering region 3 is relatively free due to its high light scattering ability. Looks bright. On the other hand, when the directional scattering region 3 is illuminated from an oblique direction perpendicular to the light scattering axis 9a and the directional scattering region 3 is observed from the front, the directional scattering region 3 is compared due to its low light scattering ability. Looks dark.

  As is clear from this, for example, when the directional scattering region 3 is illuminated from an oblique direction and observed from the front, when the directional scattering region 3 is rotated around its normal direction, the brightness becomes Change.

  Here, as an example, a case where the observer 7 observes the display body 10 by illuminating the display body 10 with the illumination light source (white light source) 6 in the positional relationship as shown in FIG. 5 will be described. When the light scattering axis 9a and the orientation direction 9b of the directional scattering region 3 are as shown in FIG. 5, the observer 7 observes the directional scattered light 13 showing the maximum light scattering ability in the direction of the light scattering axis 9a. can do.

  At this time, as shown in FIG. 2, the observer 7 can observe the pattern 12 such as characters, symbols, marks, and the like configured in the directional scattering region 3, and the shading pattern 11 arranged on the printing layer 5 is It is concealed by the strong directional scattered light 13. That is, a latent image is formed.

  If the observer 7 rotates the direction of the display body by 90 ° while maintaining the positional relationship of FIG. 5, the observer 7 can observe the directional scattered light 13 because the light scattering axis also rotates by 90 °. First, the shading pattern 11 formed on the printing layer 5 as shown in FIG. 3 can be observed.

  Therefore, it is desirable that the transparent light reflecting layer 4 has a transmittance to such an extent that the shading pattern 11 formed on the printing layer 5 can be observed. Accordingly, the transparent light reflecting layer 4 preferably has a transmittance of 60% or more. For example, when ZnS (refractive index: 2.3) is used, when the light source is vertically incident, the transparent light reflecting layer 4 has an air (refractive index of 1.0) interface. The transmittance can be calculated as about 84%, and similarly the reflectance can be calculated as about 15%.

  Further, when ITO (refractive index 1.9) is used as the transparent light reflecting layer 4, when the light source is vertically incident, the transmittance at the air (refractive index 1.0) interface is about 90%, and the reflectance is It can be calculated as about 9%.

  As described above, when considering a practical configuration, the transmittance of the transparent light reflection layer 4 is about 80% and the reflectance is about 10%.

  That is, by providing a plurality of directional scattering regions 3 with different light scattering axes 9a, a difference in brightness can be generated between them. Therefore, an image can be displayed in the directional scattering region 3 by this. In particular, by sufficiently taking the angle difference of the light scattering axis 9a (for example, so as to be orthogonal), the images displayed in the respective regions can be observed under different observation conditions.

  The brightness of the directional scattering region 3 can be controlled by other methods. For example, the greater the width of the directional scattering structure 14, the smaller the light scattering ability in the direction of the light scattering axis 9a. On the other hand, when the directional scattering structure 14 is lengthened, the light scattering ability in the orientation direction 9b is reduced.

  The shape of the directional scattering structure 14 may be the same in one directional scattering region 3. Alternatively, one directional scattering region 3 may include a plurality of convex portions and / or concave portions having different shapes.

  In the directional scattering region 3 including only the directional scattering structure 14 having the same shape, the light scattering ability can be easily designed. Further, such a directional scattering region 3 can be easily formed with high accuracy by using a fine processing apparatus such as an electron beam drawing apparatus or a stepper. On the other hand, according to the directional scattering region 3 including the directional scattering structures 14 having different shapes, scattered light having a gentle light intensity distribution can be obtained over a wide angular range. Therefore, a change in light and dark depending on the observation position is small, and a stable white color can be displayed.

  Further, the higher the degree of orientational order of the directional scattering structure 14, the greater the light scattering ability anisotropy of the directional scattering region 3.

  In the directional scattering region 3, the directional scattering structures 14 may be regularly arranged to some extent, or may be randomly arranged. For example, when the interval in the direction parallel to the light scattering axis 9a of the directional scattering structure 14 is made random, the light intensity distribution of the scattered light in the direction perpendicular to the orientation direction 9b becomes gentle. Therefore, changes in whiteness and brightness according to the observation angle are suppressed.

  Further, if the interval between the directional scattering structures 14 is reduced in the direction parallel to the light scattering axis 9a, more incident light can be scattered, so that the light scattering ability anisotropy is not deteriorated. The intensity of light can be increased. For example, if the average interval of the directional scattering structures 14 in the direction parallel to the light scattering axis 9a is 10 μm or less, it is possible to obtain a light scattering intensity sufficient to realize a display with good visibility.

  In addition, if this average space | interval is made small enough, when the directional scattering area | region 3 is comprised by the several cell, it is fully possible to make the magnitude | size of a cell into about 100 micrometers. In this case, an image can be displayed with a fineness below the resolution of the human eye under normal observation conditions. That is, a sufficiently high-definition image can be displayed.

  Since the directional scattering region 3 is composed of a plurality of fine cells, the pattern 12 such as characters, symbols and marks can be configured as a collection of fine cells. The size of the pattern 12 is preferably 2 mm or less. If the size is 2 mm or less, the pattern 12 can be mixed with the shading pattern 11 formed on the printing layer 5 described above without feeling uncomfortable. It is also possible to improve the effect of converting the arranged light and shade pattern 11 into a latent image.

  Further, the pattern 12 configured in the directional scattering region 3 may have a size of 2 mm or more as long as it is approximately the same as the size of the image formed by the shading pattern 11 disposed on the printing layer 5. The size ratio is preferably 0.8 to 1.2. Within that range, there is no sense of incongruity even if an image formed by the pattern 12 formed by the directional scattering region 3 and an image formed by the shading pattern 11 formed on the print layer 5 are mixed, and the image is arranged on the print layer 5. It is possible to sufficiently exhibit the effect of making the density pattern 11 a latent image.

  Since the directional scattering region 3 in the present invention has a light scattering structure composed of a plurality of convex portions and / or concave portions having the same direction, it has a function of scattering white light under normal illumination conditions. Observed as a light gray light and saturated color.

  As an index indicating the brightness of the directional scattering region 3, luminance or the like may be used. As a brightness evaluation method, for example, R, G, and B gradation values of the directional scattering region 3 can be measured with a CCD camera image and the brightness L can be calculated from these values. A YIQ color system is often used for conversion from RGB gradation values to grayscale images. The YIQ color system is used in the NTSC (National Television Standard Committee) and has characteristics close to human visual characteristics. If the following formula (1) is used, the luminance in the YIQ color system can be calculated.

Luminance = (0.3 × R) + (0.59 × G) + (0.11 × B) (1)
A characteristic of the directional scattering region 3 in the present invention is an effect of emitting strong scattered light. Actually, if the luminance is about 2 to 3 times the luminance value of the standard white plate, the light and shade pattern 11 arranged on the printing layer 5 can be sufficiently latentized.

  By making the directional scattering region 3 white directional scattered light 13 having high luminance and saturation, the effect of concealing the light and shade pattern 11 arranged in the printing layer 5 and forming a latent image can be enhanced.

  Furthermore, at a position where the directional scattered light 13 cannot be observed, the shading pattern 11 of the printing layer 5 can be clearly confirmed, and can be used as an authenticity determination function that is easy to prevent forgery.

  EXAMPLES Hereinafter, although an Example demonstrates this invention further in detail, these are illustrations and do not limit this invention at all.

  In the display 10 shown in FIG. 1, a polyethylene terephthalate (PET) film as the light transmissive substrate 1, an ultraviolet curable resin as the relief structure molding layer 2, and a depth of the order of several hundred nm as the directional scattering region 3. The directional scattering structure 14 formed at a random pitch is formed. Further, a zinc sulfide (ZnS) layer was coated as the transparent light reflecting layer 4 by a sputtering method to about 50 nm. As the printing layer 5, white paper was used, and a light and shade pattern 11 having a size of 2 mm was formed on the surface of the printing layer 5 by an ink jet printer as shown in FIGS.

  Further, the pattern 12 having a size of 2 mm was formed by forming the directional scattering region 3 in cell units of several μ order by electron beam drawing.

  When the produced display body 10 is illuminated with a white light source and observed, the pattern 12 formed in the directional scattering region 3 as shown in FIG. 2 is observed as light having strong directivity in the direction of the light scattering axis 9a. I confirmed that I can do it. At this time, it was confirmed that the shading pattern 11 formed on the printing layer 5 was formed into a latent image with light from the directional scattering region 3 and was not observable.

  Next, when the display 10 is rotated by 90 ° and observed, the light from the directional scattering region 3 cannot be observed, so that the shading pattern 11 formed on the printing layer 5 can be confirmed as shown in FIG. .

  FIG. 6 shows the change in luminance of the scattered light emitted from the directional scattering region 3 when the observation angle is changed in the display body 10 of Example 1 and the luminance of the light and shade pattern 11 formed on the printing layer 5. The change is shown by comparison, and the horizontal axis indicates the observation angle [°], and the vertical axis indicates the relative luminance (relative value with respect to the standard white standard).

  As is clear from FIG. 6 above, when the observation angle with respect to the display body 10 is changed, the luminance change of the scattered light emitted from the directional scattering region 3 is the luminance change of the light and shade pattern 11 formed in the printing layer 5. Very large compared to.
