Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an image forming body having a hologram image and display information consisting of a group of fine line-shaped uneven patterns.

[Prior art and its problems] As an image forming body having a pattern with a fine unevenness on its surface, a group of fine line-like uneven patterns are formed on the surface of a sheet-like substrate having metallic luster for each pixel. There is an image-forming body that is shaped with slight changes to produce a so-called opal effect. To manufacture this image forming body, for example, a pattern is applied, if necessary, to the aluminum surface of a wax-laminated aluminum foil paper, and then a group of fine line-shaped uneven patterns are formed by changing the line direction little by little. This is done by pressing a press plate provided with a combination of embossed patterns.

In such an image forming body, the line directions of the line-like uneven patterns on the surface are different, so the direction of reflected light on the surface changes variously, and when the viewing angle or direction is changed, each line pattern is different. The shading and brightness of the line-shaped uneven pattern group changes dynamically, creating an extremely brilliant effect (opal effect). This image-forming body with an opal effect is difficult to manufacture because the embossed pattern used during production is also difficult to register with the pattern pre-formed on the sheet-like substrate. difficult to counterfeit. However, conventional image forming bodies simply change the inclination angle of the line-shaped uneven pattern that forms display information such as backs and characters, and the display information is limited to one type.
In addition to being unable to display complex information such as multiple types of information or images of people and scenery, the anti-counterfeiting effect was not always sufficient.

Therefore, the inventors of the present invention have proposed a method that is easy to manufacture and that
In Japanese Utility Model Application No. 168051/1984, we previously proposed an image forming body that can display multiple types of information and complex image information such as people and landscapes, and is highly effective in preventing counterfeiting.
As a result of further research, the inventors of the present invention found that
It is easy to manufacture and also has an opal effect.
We have developed an image-forming body that is even higher than that of No. 168051, has a richer hologram image, and can fully exhibit anti-counterfeiting effects and aesthetic effects.

[Means for Solving the Problems] The present invention provides a first hologram image formed in a predetermined area on the surface of a first sheet-like substrate having metallic luster, and a metal hologram image provided on the first sheet-like substrate. A second hologram image formed in a predetermined area on the surface of a second sheet-like substrate having gloss, a protective layer covering the first hologram image and the second hologram image, and overlapping with the second hologram image. The image forming body is characterized in that it includes display information consisting of a group of fine line-shaped concavo-convex patterns of a predetermined inclination angle formed on the protective film.

Here, the image forming body of the present invention can be applied not only to plastic cards such as credit cards and ID cards, but also to telephone cards, labels, packages, etc. made of various other materials.

[Function] According to the image forming body according to the invention, a first hologram image is formed on the surface of the first sheet-like substrate having metallic luster, and a first hologram image is formed on a predetermined area of the first sheet-like substrate including the first hologram image. A second sheet-like substrate on which two hologram images are formed is provided, and a protective layer covering the first hologram image and the second hologram image is provided, and a predetermined inclination is provided on the protective layer so as to overlap with a predetermined area of the second hologram image. Since the display information consists of a group of line-shaped uneven patterns with fine angles, it is easy to manufacture, and it further enhances the opal effect and enriches the hologram image, fully exhibiting anti-counterfeiting effects and aesthetic effects. It is something that can be done.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view showing a schematic configuration of an embodiment of the present invention. In the figure, reference numeral 1 denotes a first sheet-like substrate having metallic luster and made of, for example, a vapor-deposited layer of aluminum. A TOPPAN first hologram image 2 consisting of interference fringes with a groove pitch width of 0.5 to 2 μm and a height difference of 0.5 to 1 μm, for example, is formed on a predetermined area of the surface of the first sheet-like substrate 1. On a predetermined area of the first sheet-like substrate 1 including the second hologram image 2, a second sheet-like substrate 3 having metallic luster is placed.
is provided. As shown in FIG. 2, a second hologram image 4 consisting of, for example, a large number of rectangular patterns is formed in a predetermined area on the surface of the second sheet-like substrate 3. As shown in FIG. A first sheet containing a second sheet-like substrate 1
A protective layer 5 covering the first hologram image 2 and the second hologram image 4 is formed on the sheet-like substrate 1 . On the area of the protective layer 5 that overlaps with the second hologram image 4, a circular pattern consisting of a plurality of linear uneven pattern groups 6a with a groove pitch width of 60 to 90 μm, a height difference of 10 to 20 μm, and different inclination angles is formed. Display information 6
is formed.

Thus, the image forming body 10 formed in this way
By incorporating it into a predetermined portion of the card base material 12 via the adhesive layer 11, the complex information display of the first and second hologram images 2 and 4 and the display information 6 not only improves the aesthetic effect of the card. In addition, counterfeit prevention can also be fully demonstrated. In particular, the display information 6 consisting of the second hologram image 4 and the linear unevenness pattern group 6a has a groove pitch width of about 50 times and a height difference of the unevenness of about 20 times, so the second hologram image 4
and display information 6 can be clearly displayed. Note that, of course, in a region that does not overlap with the second hologram image 4, the content of the first hologram image 2 can be clearly and clearly displayed alone. In this way, the anti-counterfeiting effect and aesthetic effect of the card can be further enhanced. Furthermore, the image forming body 1
0 can be easily manufactured by simply employing a process of forming the linear concavo-convex pattern 5a using a conventional foil stamping method or intaglio printing, and a hologram processing process.

[Effects of the invention] As explained above, the image forming body according to the invention is easy to manufacture, further enhances the opal effect, enriches the hologram image, and has sufficient anti-counterfeiting effect and aesthetic effect. It is something that can be demonstrated to the fullest.
