Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an image forming body in which a fine line-shaped concavo-convex pattern whose direction is changed little by little for each pixel is formed on a printed image.

[Prior Art] Affix aluminum foil on a synthetic resin substrate such as an information card,
There is an image forming body on which a fine line-shaped concavo-convex pattern group whose inclination angle is changed little by little according to the pixel is formed to display display information such as characters.

In addition, the whole pattern is printed on the metallic glossy surface of aluminum vapor-deposited paper or synthetic paper on which aluminum foil is pasted, and the direction is changed little by little for each pixel on this pattern, and a fine line-shaped concavo-convex pattern group matched to this pattern. There are some that have been applied.

These line-shaped uneven pattern groups are printed on the surface of the wax-laminated aluminum foil with necessary information such as characters, or after printing a pattern, a fine line-shaped uneven pattern group is slightly moved in the direction. It is manufactured by pressing a press plate, which is formed into a desired embossed pattern by changing it one by one, onto the printing surface. Forming the line-shaped uneven pattern in this manner is called opal processing.

In such an image forming body, since the direction of the parallel line uneven pattern group changes little by little, the reflection direction of the light reflected by each parallel line uneven pattern group on the surface changes variously,
Depending on the viewing direction and angle, the density and brilliance of the metallic luster, and when superimposed on the printed image, in addition to this, the color of the ink dynamically changes. Therefore, a visual effect called an extremely splendid opal effect is exhibited. Further, in the image forming body having the opal effect, it is very difficult to manufacture the emboss pattern formed on the press plate, and this registration is very difficult. Is difficult for a third party to forge.

[Problems to be solved by the invention] However, in the case where an aluminum foil is pasted on a synthetic resin base and an opal is applied on the base, since the base has rigidity and complicated processing is difficult, It was only possible to partially change the inclination angle of the line-shaped concavo-convex pattern and display the display information such as the background and characters, and it was not possible to provide a design.

Further, it is possible to print the entire pattern on the metallic glossy surface of the synthetic paper and attach the opal-processed product to the resin substrate to provide the pattern on the entire surface. In this case, it is necessary to perform adhesive lamination from the top and bottom with a transparent hard resin with the opalized synthetic paper as the center. However, when the image forming body is formed in this manner, the irregularities on the opalized surface are lost in the transparent resin layer, and the brilliant visual effect is weakened in this transparent resin layer.

The present invention has been made in view of the above, and an object of the present invention is to provide an image forming body capable of easily forming a linear uneven pattern on an image of complicated information or a person, a landscape, etc. on a rigid substrate. And

[Means for Solving the Problems] An image-forming body according to the present invention comprises a sheet-like base body having a resin layer formed on the surface of a base layer, and at least a part of the resin layer with a metal vapor deposition surface facing outside. It is characterized in that it is provided with an adhered metal vapor deposition foil and an image consisting of a group of fine line-shaped uneven patterns having a predetermined inclination angle formed on the metal vapor deposition foil and the resin layer.

Furthermore, it is preferable to color-print with a transparent ink on the metal vapor deposition surface so as to be superimposed on this image.

[Operation] According to this image forming body, the metal vapor deposition foil is adhered on the resin layer of the substrate, and the adhered metal foil is made of opal processing, that is, a group of fine line-shaped concavo-convex patterns having a predetermined inclination angle. An image is formed. Since the resin layer is arranged inside the metal vapor deposition foil, it is possible to form the groove pitch of the linear uneven pattern finely, and even when the uneven depth is deep, the influence does not reach the base layer, Therefore, a complex and clear image is formed on the metal vapor deposition foil attached to the substrate by the fine line-shaped uneven pattern group having a predetermined inclination angle. An image formed by a line-shaped uneven pattern group can be applied over the entire surface, and the shade and brightness of the image are variously changed depending on the viewing angle and direction.

Furthermore, by superimposing on this image and performing color printing with a transparent ink, an extremely splendid visual effect is produced. In addition, this ink protects the metal vapor deposition surface so that the gloss is not lost forever.

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

[Example] FIG. 1 shows a sectional view of a metal vapor deposition foil, and FIG. 2 shows a sectional view of a base body such as a telephone card to which the metal vapor deposition foil is attached.

The metal vapor deposition foil 1 of the present embodiment is formed as a transfer foil, and has a vapor deposition foil 2 in which aluminum is vapor deposited on the surface of a sheet-shaped thin foil body. An adhesive layer 3 is laminated on the back surface of the vapor deposition foil 2, that is, the lower surface of FIG. The surface side of the vapor deposition foil 2 is laminated on the protective layer 5 with the peeling layer 4 interposed therebetween, and the releasability between the protective layer 5 and the vapor deposition foil 2 is improved. In this embodiment, the protective layer 5 is made of polyethylene terephthalate (PET) having a thickness of 12 μm.

As shown in FIG. 2, the substrate 6 can be formed, for example, on a telephone card, and on the back surface of the base layer 7, a magnetic layer 9 for recording magnetic information and a silver hiding layer 10 for covering the magnetic layer 9 are sequentially laminated. The resin layer 8 is laminated on the surface, that is, on the upper surface in FIG.

The resin layer 8 can be formed of an appropriate material,
The resin layer 8 is preferably a polyester resin, and when it is laminated on the base layer 7, it can be formed by roll coating or silk screen printing. The base layer 7 can also be made of an appropriate material, but in this embodiment, it is made of PET having a thickness of 188 to 250 μm.

This metal vapor deposition foil 1 is pasted on the resin layer 8 of the substrate 6 with the adhesive 3 inside, and then the protective layer 5 of the metal vapor deposition foil 1 is peeled off. Since the peeling layer 4 is disposed between the protective layer 5 and the vapor deposition layer 2, the peeling property is good, and the vapor deposition layer 2 maintains good flatness with the aluminum vapor deposition surface as the surface.
Then, the metal vapor deposition layer 1 laminated on the substrate 6, that is, the vapor deposition layer 2 from which the protective layer 5 is peeled off and the metal vapor deposition surface is exposed, is subjected to opal processing for forming a fine line-shaped uneven pattern group.

FIG. 3 shows a stamper 11 used for this opal processing. The stamper 11 of this embodiment is formed of a copper plate, and the lower surface of the stamper 11 has pixel regions 12a, 12 for forming a desired image.
b, 12c, 12d, and 12e, an embossing pattern that is a master of a line-shaped concavo-convex pattern group in which the direction and the groove pitch and the depth are slightly changed is formed, and this embossed pattern surface is formed. Nickel plated. This embossed pattern is configured such that a group of parallel line-shaped concave-convex pattern groups corresponding to mutually adjacent regions such as the region 12a and the region 12b are formed by slightly changing the direction and the groove pit and the concave-convex depth. There is. It is preferable that the groove pitch in the line-shaped uneven pattern group formed by the stamper 11 is 60 to 90 μm and the uneven depth is 10 to 20 μm.

By pressing this stamper 11 against the vapor deposition layer 2 laminated on the substrate 6 and simultaneously heating it, a fine line-shaped uneven pattern group for forming pixels is formed on the surface of the vapor deposition layer 2 respectively. In this case, since the resin layer 8 is arranged between the vapor deposition layer 2 and the base layer 7 of the substrate, and the adhesive layer 3 is also arranged, a deeper uneven pattern can be formed,
The depth can be controlled freely. Further, the base layer 6 and the magnetic layer 9 on the back surface are not affected at all, and the data reading is not hindered.

The magnetic layer 9 may be provided with required data in advance, or may be provided with data after the opal processing as described above.

The image forming body formed in this manner forms a slightly different fine line-shaped pattern group for each of the pixel regions 12a, 12b, 12c, 12d, and 12e, so that an image is formed depending on the viewing angle and direction. The shade, brilliance, and color of the complex change.

Further, as shown in FIG. 4, the surface of the vapor deposition layer 8 on which the line-shaped uneven pattern group is formed is color-printed with a transparent ink, and the back surface of the silver concealing layer 10 is also provided with characters 14 and the like as necessary. To print. A transparent ink layer of a pattern printed on the vapor deposition layer 8 is indicated by reference numeral 13.

In this color printing, a pattern is printed in accordance with opal processing, that is, in accordance with pixel regions 12a, 12b, 12c, 12d, and 12e formed by a line-shaped uneven pattern group formed on the surface of the vapor deposition layer 8. In the pattern printed in this way, the reflection direction of light slightly differs for each pixel, so the shade and brightness of the color changes dynamically depending on the viewing angle,
Further, since the transparent ink is used, the metallic luster of the vapor-deposited layer is overlapped, and a visual effect that is a more opal effect than the conventional one is produced. Furthermore, since the vapor deposition layer 8 is covered with the transparent ink layer 13, this metallic luster is not lost forever.

In the above embodiment, the case of a prepaid card such as a telephone card has been described.
It can also be used for information cards such as cards, or for other decorations.

[Effects of the Invention] As described above, according to the image forming body of the present invention, it is possible to easily form a line-shaped uneven pattern group as a minute and clear image of complicated information or a person or landscape on a rigid substrate. It is possible to form an image, and by superimposing the image on the image by color printing with a transparent ink, an extremely gorgeous image can be retained forever.
