BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming body for displaying information such as a picture by forming a fine line-shaped uneven pattern group.

[0002]

2. Description of the Related Art As such an image-forming body, for example, a plurality of fine line-shaped uneven pattern groups are formed on the surface of a sheet-like base material having a metallic luster by slightly changing the line for each pixel. There is.

In this image forming body, for example, a pattern is formed on an aluminum surface such as a wax-laminated aluminum foil, if necessary, and then a fine line-shaped uneven pattern group is formed.
The press line on which the embossed pattern in which various combinations are formed is pressed by changing the line direction little by little.

In such an image forming body, since the parallel line directions in the parallel line-shaped concave-convex pattern group on the surface are different from each other, the reflection direction of the reflected light on the surface is changed to change the viewing angle and direction. When each is changed, the shading and brilliance of each line-shaped uneven pattern group dynamically changes, producing an extremely splendid effect (opal effect).

Further, in such an image forming body, as described in Japanese Utility Model Publication No. 5-8160, a line-shaped uneven pattern group having different inclination angles and a line-shaped uneven pattern group for the back thereof are provided. Along with the formation, the technique of forming these parallel line-shaped uneven pattern groups, back line-shaped uneven pattern patterns, and other parallel line-shaped uneven pattern groups having different inclination angles and other back line-shaped uneven pattern groups is known. is there. With the image forming body having such a configuration, it is possible to display complicated image information by changing the design depending on the viewing direction.

[0006]

However, in such an image forming body, a plurality of kinds of patterns are made different depending on the viewing angle only by the line-shaped uneven pattern group and the other line-shaped uneven pattern group. However, if possible, if the shade of the pattern changes, there is a demand that a more beautiful effect can be produced.

Therefore, an object of the present invention is to provide an image forming body which can change the information depending on the viewing direction and can also change the color tone of the information at the same time to produce a more beautiful effect.

[0008]

According to a first aspect of the present invention, there is provided an image forming body in which an embossed pattern having a parallel line-shaped concave-convex pattern is formed on a laminate in which a light reflecting layer and a coloring layer are formed on a substrate. The embossed pattern is formed on a plurality of strips, and each of the strips has an information display area formed of a group of fine linear concavo-convex patterns each having a predetermined inclination angle, and an inclination different from the inclination angle in contact with the information display area. A large number of information display strips formed in the back display area consisting of a line-shaped uneven pattern group for back with an angle, and a plurality of strips formed on these strips, and each of these strips has a line-shaped uneven pattern group and a back pattern.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram of an image forming body. A reflective foil 2 as a light-reflecting layer is formed on the sheet substrate 1, and a color layer 3 is formed on the sheet substrate 1 with ink or the like as a colored layer.
Has been applied.

The reflective foil 2 having the color 3 is provided with an embossed pattern 4 formed by a line-shaped uneven pattern group. The embossed pattern 4 is formed by pressing the reflective foil 2 with a pressing press on which the embossed pattern is formed.

The embossed pattern 4 is formed on a plurality of strips, and each of the strips has an information display area consisting of a fine line-shaped uneven pattern group having a predetermined inclination angle.
And a large number of information display strips formed in the back display region, which are in contact with the information display region and have a tilt angle different from the tilt angle, and which are formed in a plurality of strips, Formed from another line-shaped concave-convex pattern group and another line-shaped concave-convex pattern group for back, each of which has an inclination angle different from that of the parallel-shaped concave-convex pattern group and the line-shaped concave-convex pattern group for back, respectively. The other information display strips are formed alternately.

Specifically, a plan view of the image forming body shown in FIG.
Description will be made with reference to the enlarged view of FIG. 1A shown in FIG. On this image forming body, for example, the respective character information 5 and 6 of I and T are formed so as to overlap with each other with a slight distance therebetween.

That is, the I character information 5 has a width L1 (about 0.
It is composed of a large number of I marking strips 53 (2 mm).
The I display region 51 and the I back display region 52 have a line-shaped uneven pattern group having a height difference of 10 to 20 μ between concave and convex portions and a pitch width of 60 to 90 μ and a line-shaped uneven pattern group for back, respectively. Has been formed.

Each inclination angle of the line-shaped uneven pattern group is 1
It is formed at 50 degrees. The inclination angle of each of the back and forth linear concavo-convex pattern groups is formed to be 70 degrees. On the other hand, T
The character information 6 is composed of a large number of T display stripes 63 each having a width L2 (about 0.2 mm), which includes a T character display area 61 and a T back display area 62.

A T display area 61 and a T back display area 62
Is formed of a line-shaped uneven pattern group for back and a line-shaped uneven pattern group for back each having a height difference between the concave and convex parts of 10 to 20 μ and a pitch width of 60 to 90 μ.

Each inclination angle of the line-shaped uneven pattern group is 3
It is formed at 0 degrees. The inclination angle of each of the back and forth linear uneven pattern groups is 110 degrees. As described above, in both the case of the I character information 5 and the case of the T character information 6, the inclination angle difference between the line-shaped uneven pattern group and the back line-shaped uneven pattern group is set to 80 degrees.

In addition, a large number of I indicating strips 53 and T indicating strips 63
Are formed so that they are alternately adjacent to each other. On the other hand, FIG. 4 shows a large number of these I-indicating strips 53.
And each cross-sectional shape of the T display strip 63 is shown. Color 3 is applied to the line-shaped uneven pattern group and the back line-shaped uneven pattern group in synchronization with the directions of these uneven patterns.

By forming the reflective foil 2, these parallel line-shaped concavo-convex pattern groups have the effect of repeatedly changing the reflectivity by selectively revealing or hiding the color 3 depending on the viewing direction.

In this color 3 structure, magenta stripes 70 are formed along the convex portions of the line-shaped concavo-convex pattern and cyan stripes 71 are formed in the concave portions. In addition to the magenta stripe 70 and the cyan stripe 71, the configuration of the color 3 is
Yellow, white and black may be applied as required.

With this configuration, when the image forming body is viewed from different directions, the I character information 5 and the T character information 6
The respective display information different from each other appears, and the color of each display information of the I character information 5 and the T character information 6 changes depending on the viewing direction.

Moreover, due to the interaction between the inclination angle of each emboss pattern and the color 3, the display information appearing depending on the viewing direction and the appearing color change correspondingly. That is, as shown in FIG. 4, the light emitted from the light source F1 to the image forming body is reflected by the magenta stripes 70 and the cyan stripes 72, respectively, and the reflected light of the magenta stripes 70 is reflected in the direction of the viewpoint Q1. However, the reflected light of the cyan stripe 71 is reflected in the direction of the viewpoint Q2 different from the viewpoint Q1.

Therefore, when the observer is at the viewpoint Q1 and looks at the image forming body while the light is being emitted from the light source F1, the reflected light from the magenta stripe 70 is observed to observe the magenta color, and the edge observation is performed. When the person moves and looks at the image forming body from the viewpoint Q2, the reflected light from the cyan stripe 71 is received to observe the cyan color.

Further, a light source F having a light incident angle different from that of the light source F1
When light enters the image forming body from 2, for example, cyan stripes 7
The light radiated to 1 is reflected in the direction of the viewpoint Q1. Therefore, if the observer is at the viewpoint Q1 and looks at the image forming body while the light is being emitted from the light source F2, the observer will receive the reflected light from the cyan stripe 71 and observe the cyan color. Even if the positions are the same, if the light incident directions from the light sources F1 and F2 are different, the color observed by the observer changes.

[0025] However, the display information of the I character information 5 or the T character information 6 can be changed by the line-shaped uneven pattern group and the back line-shaped uneven pattern group depending on the viewing direction of the observer. The color of the I character information 5 or the T character information 6 can be changed to magenta or cyan from the viewing direction of the observer by adding the color 3 of.

Further, the display information can be set to a desired plurality, and hidden character information and the like can be incorporated as appropriate. Further, since the display information becomes complicated, the forgery prevention effect can be enhanced. Moreover, in manufacturing, the conventional foil stamping method and intaglio printing can be applied without changing the processing steps, and the manufacturing can be facilitated.

When applying such an image forming body, it can be applied by pasting it on a card, or a bag or box of confectionery or the like. The present invention is not limited to the above-mentioned one embodiment, and may be modified within the scope of the invention.

In the above-described embodiment, the case where two types of character information, I character information 5 and T character information 6, are displayed has been described. However, the present invention is not limited to this, and the line-shaped irregularities forming the first display information. The inclination angle of each pattern is 80 degrees, the inclination angle of the back parallel uneven pattern is 155 degrees, and each inclination angle of the parallel uneven patterns forming the second display information is 30 degrees. The inclination angle of the back linear uneven pattern is formed to be 105 degrees, each inclination angle of the parallel uneven pattern constituting the third display information is set to 130 degrees, and the inclination angle of the back parallel uneven pattern is set to 130 degrees. It may be formed at 55 degrees to display three types of information.
