  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(Configuration of card 1)
FIG. 1 is a view showing the surface of a card 1 which is a pattern forming object of the present embodiment. As shown in the figure, the card 1 is made by visualizing a printed pattern 3, a hologram pattern 5 on the printed pattern 3, and a relief pattern 7 on the hologram pattern 5. In the present embodiment, the back surface (not shown) of the card 1 also has a printed pattern 3.

  FIG. 2A is a diagram showing a cross-sectional configuration of the card 1. As shown in the figure, in the card 1, a printed pattern layer 13 a is formed on the upper surface of the core base material 11, and a transparent overfilm layer 19 a and a hologram layer 15 are provided on top of each other in this order. On the other hand, a printed pattern layer 13b is formed on the lower surface of the core substrate 11, and a transparent overfilm layer 19b is provided on the printed pattern layer 13b. A groove 17 for visualizing the relief pattern 7 is formed on a part of the surface of the hologram layer 15.

  The core substrate 11 is obtained by adding a pigment such as a white pigment to a plastic material such as PET-G (Polyethylene Terephtalate Glycol-modified) or vinyl chloride resin according to the color of the substrate.

  The printed pattern layers 13a and 13b are layers on which ink is printed on both surfaces of the core substrate 11 by offset printing, screen printing, or the like. The pattern formed by printing in the printed pattern layers 13a and 13b is the printed pattern 3 described above.

  A transparent film made of PET-G, vinyl chloride resin or the like is used for the transparent overfilm layers 19a and 19b.

  The hologram layer 15 is obtained by recording the shape of interference fringes between the reference light irradiated on the object and the reference light reflected from the object on the surface of the transparent sheet as a diffraction grating with fine irregularities. The pattern visualized as a hologram in the hologram layer 15 is the hologram pattern 5 described above.

  A plurality of grooves 17 are formed separately from the irregularities of the diffraction grating at positions corresponding to the relief pattern 7 on a part of the surface of the hologram layer 15. An example of the arrangement of the grooves 17 is shown in FIG.

  In this embodiment, as shown in Japanese Patent Application Laid-Open No. 2009-12411 and the like, a group 17a composed of a plurality of parallel linear grooves 17 is changed while changing the direction, width, interval, length, etc. of the grooves 17. A plurality of layers are formed, and a three-dimensional reflection characteristic is expressed by using the anisotropic reflection characteristic of light generated thereby. In this way, a pattern having a three-dimensional effect is visualized by the groove 17. This pattern is the relief pattern 7 described above. However, the arrangement of the grooves 17 for visualizing the pattern by the anisotropic reflection characteristic of light is not limited to this. For example, there are cases where hairline-shaped grooves 17 and concentric grooves 17 are arranged.

  FIG. 2C is a diagram schematically showing an enlarged cross section of a range a in FIG. As shown in the figure, the depth and width of the unevenness of the diffraction grating on the surface of the hologram layer 15 is 1 μm or less, for example, about several hundreds of nanometers which is the same as the wavelength of light. On the other hand, the depth and width of the groove 17 for expressing the relief pattern 7 can be about several tens of μm. As described above, since the unevenness of the diffraction grating of the hologram layer 15 and the scale of the groove 17 are different by about 100 times, the hologram pattern 5 and the relief pattern 7 do not interfere with each other to impair the design of each other. The present inventor has found that the hologram pattern 5 and the relief pattern 7 can be expressed without interfering with each other, and thus the configuration of the card 1 as described above has been achieved.

(Method for manufacturing card 1)
Next, a method for manufacturing the card 1 will be described.

  In this embodiment, when manufacturing the card | curd 1, the sheet | seat 10 of the core base material 11 shown to Fig.3 (a) is used. In the sheet 10, a plurality of card forming portions 1a are multifaceted. In the present embodiment, printed pattern layers 13 a and 13 b are formed on both surfaces of the sheet 10 of the core substrate 11 by printing the printed pattern 3 corresponding to each card forming portion 1 a. FIG. 4A shows a cross-sectional configuration of the card forming portion 1a at this time.

  Next, as shown in FIG. 4B, the transparent overfilm layers 19a and 19b are overlaid on the printed pattern layers 13a and 13b, respectively. At this time, each of the transparent overfilm layers 19a and 19b may be temporarily bonded. The planar size of the transparent overfilm layers 19a and 19b is approximately the same as that of the sheet 10.

Thereafter, as shown in FIG. 4C, the hologram layer 15 is laminated on the surface of the transparent overfilm layer 19a. In the present embodiment, as shown in FIG. 3B, a base film 20 such as a PET film on which the hologram layers 15 of the card forming portions 1a are multifaceted is used, and the card forming portions 1a and the card 10 of the sheet 10 are formed. The hologram layer 15 is overlaid on the transparent overfilm layer 19a with the position of the portion 1a aligned.
Next, a smooth stainless steel plate (not shown) is pressed from the base film 20 side and the transparent overfilm layer 19b side, heated and pressurized, and the hologram layer 15 is transferred onto the transparent overfilm layer 19a. Thereafter, the base film 20 is peeled off as shown in FIG.

Next, as shown in FIG. 4 (e), a stainless steel plate 25, which is a mold, is pressed against the hologram layer 15, and a smooth stainless steel plate 29 is pressed from the transparent overfilm layer 19b side. Pressurize. The heating temperature is 60 to 80 ° C. or more, which is the flexible temperature of each layer, for example, 120 ° C. The pressure to be applied is, for example, about 25 kg / cm ² .

  FIG. 5 is a diagram for explaining an example of the stainless steel plate 25. FIG. 5A shows a surface that is pressed against the hologram layer 15. FIG. 5B is an enlarged view of the convex portion 25 a of the stainless steel plate 25.

  As shown in the drawing, a convex portion 25a having a shape corresponding to the groove 17 (see FIG. 2B, etc.) for expressing the relief pattern 7 of each card forming portion 1a is processed on the stainless steel plate 25. The planar size of the stainless steel plate 25 is slightly larger than that of the sheet 10.

  Through the process described with reference to FIG. 4E, the surface of the hologram layer 15 is recessed in accordance with the shape of the convex portion 25a to form the grooves 17, and the layers are laminated. Thereby, as shown in FIG. 6, the raw fabric in which each card forming portion 1a is multifaceted is manufactured.

  Thereafter, each card 1 is completed by punching out each card forming portion 1a from the original fabric. In the present embodiment, six card forming portions 1a are multi-faced to the original fabric to produce six cards 1 at a time, but the number can be determined as appropriate.

  As described above, in the card 1 according to the present embodiment, the hologram design 5 and the relief design 7 are visualized, so that the design and decoration of the card can be enhanced by the expression. In addition to the hologram pattern 5, the relief pattern 7 is difficult to reproduce the same pattern, so that the forgery prevention property of the card 1 is improved. Further, in the present embodiment, the printed pattern 3 below the pattern as well as these patterns can be visually checked, and the design and decoration are further enhanced.

  However, the present invention is not limited to this. For example, as a modification of the present embodiment, only the printed pattern layer 13a can be formed on the card 1. Alternatively, it is possible to omit both the printed pattern layers 13a and 13b without printing on the core base material 11.

  Further, in this embodiment, the hologram layer 15 is formed on the entire surface of the card 1 to visualize the hologram pattern 5, and the groove 17 is provided in a part of the hologram layer 15 to visualize the relief pattern 7. However, the present invention is not limited to this. For example, the hologram layer 15 may be formed by a part of the card 1 and the groove 17 may be provided thereon. Thus, as long as the relief pattern 7 is visualized in addition to the hologram pattern 5 by the grooves 17 provided in the hologram layer 15, the arrangement and the like can be determined as appropriate.

  In the present embodiment, an example in which the hologram pattern 5, the relief pattern 7 and the like are formed on the card 1 has been shown, but the pattern formation according to the present invention is not limited to this. For example, it is also possible to form and visualize the hologram pattern 5 and the relief pattern 7 on the same method using various ticket materials such as tickets and various packaging materials such as envelopes as a base material.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It will be apparent to those skilled in the art that various changes or modifications can be conceived within the scope of the technical idea disclosed in the present application, and these naturally belong to the technical scope of the present invention.
