The reflected light beams interfere with each other and the desired Moire patterns are formed on the sheet surface.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glittering decorative sheet that can be used in various fields such as wrapping paper, wrapping bags, and wallpaper. More specifically, the light is reflected to form various reflected light patterns on the sheet surface. Glittering decorative sheet.

[0002]

2. Description of the Related Art Conventionally, as a glittering decorative sheet that exhibits a design effect by surface reflected light, a sheet formed by vapor-depositing a metal such as aluminum on the surface of a base material such as resin-coated paper is known.

However, in the case of this vapor deposition sheet, only a uniform light reflection is exhibited, and a pattern is not formed by the reflected light itself.

[0004]

SUMMARY OF THE INVENTION Therefore, the technical problem to be solved by the present invention is to provide a brilliance in which external light is reflected to form various reflected light patterns, in particular, moiré reflected light patterns causing moire on the surface. To provide a sex decorative sheet.

[0005]

In order to solve the above problems, the present invention provides a glittering decorative sheet having the following constitution.

That is, this sheet is formed by sequentially laminating a plurality of halftone dot printing layers made of transparent ink and a light reflecting layer on the lower surface of the transparent surface layer, and forming each layer between the halftone dot printing layers. By relatively shifting the halftone dots to be formed and the other halftone dots, the reflected light pattern of external light incident from the base film side is configured to exhibit a desired moire pattern.

In the above-mentioned structure, the halftone dot printing of the halftone dot printing layer is carried out by printing with a plate composed of concave dots which are regularly formed along a number of parallel horizontal and vertical parallel lines. The print layer is formed by gravure printing or the like.

In the above structure, as the material for forming the transparent surface layer, for example, polyester, stretched nylon, or stretched polypropylene is preferably used. On the other hand, as the material for forming each dot printing layer, for example, A two-component curable resin containing nitrified cotton or an acrylic polyol resin as a main component and an isocyanate resin as a curing agent is preferably used. On the other hand, as a material for forming the light reflection layer, for example, aluminum, gold, yttrium,
Tin oxide or the like is preferably used. Further, each halftone dot printing layer is formed by gravure printing or the like.

According to the above construction, a part of the external light transmitted through the transparent surface layer is reflected on the surface of each halftone dot of each halftone dot printing layer, and another part of the external light is halftone dot. After passing through, the light is reflected by the mirror surface of the light reflection layer to reach outside light. Further, another part of the external light does not pass through the halftone dots and is directly reflected by the light reflection layer to reach the external light. Since these halftone dots have a laminated structure, the reflected light reflected on each surface of the halftone dots not only becomes reflected light with a three-dimensional effect, but the upper surface, which is the reflection surface of the light reflection layer, is printed with halftone dots. Since it is formed corresponding to the unevenness on the lower surface of the layer, the reflected light reflected on this upper surface exhibits a glittering reflected light pattern corresponding to the unevenness. Furthermore, since the halftone dots in the stacked state are relatively displaced,
The reflected lights reflected by the respective surfaces of the halftone dots interfere with each other to generate a desired moire pattern, and thereby the design effect is very excellent.

In the above structure, the halftone dots can be relatively displaced by the following method. That is, the halftone dots of each halftone dot printing layer are regularly arranged in the same vertical line direction and the same horizontal line direction orthogonal to the vertical line direction, respectively, and the same vertical line direction or the same vertical line direction. By changing the number of halftone dots per unit length in the horizontal line direction for each halftone dot printing layer, the halftone dots between the halftone dot printing layers can be relatively shifted.

The relative displacement of the above-mentioned halftone dots can also be realized as follows. That is, the halftone dots of each halftone dot printing layer are arranged regularly in the vertical line direction and in the horizontal line direction orthogonal to the vertical line direction, and in each vertical line direction or each horizontal line direction. The number of halftone dots per unit length is configured to be the same, and by shifting each halftone dot printing layer relative to one point by a predetermined angle,
Halftone dots between the respective halftone dot printing layers may be relatively shifted. By doing so, the degree of interference between the reflected lights is increased, and the moire effect is maximized.

Furthermore, the relative displacement of each halftone dot can be realized by simultaneously adopting the above two methods.

In each of the above constructions, it is preferable that the inks constituting the respective halftone dots have different colors between the respective halftone dot printing layers. In this way, the decorative pattern corresponding to the desired moire pattern is freely colored, which can further enhance the design effect.
