BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glittering decorative sheet which can be used in various fields such as a packaging bag, a wrapping paper, a packaging box, and a wallpaper. The present invention relates to a glitter decorative sheet formed on a sheet surface.

2. Description of the Related Art Conventionally, as a glossy sheet which exerts a design effect by surface reflected light, an evaporation sheet formed by evaporating a metal such as aluminum on a surface of a base material such as resin-coated paper is known. However, in the case of this vapor-deposited sheet, only a uniform light reflection is produced, and a pattern is not formed by the reflected light itself.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a glittering decorative sheet in which external light is reflected and various reflected light patterns are formed on the surface.

[0004]

In order to solve the above problems, according to the present invention, there is provided a glittering decorative sheet having the following constitution.

That is, this decorative sheet has a laminated structure in which a base layer, a light reflecting layer, and a transparent resin layer are sequentially laminated from bottom to top. This light reflection layer is preferably a metal deposition layer. The transparent resin layer has an upper surface portion and a planar upper surface portion of a desired concavo-convex pattern having a certain regularity and formed in accordance with a desired decorative pattern. Furthermore, a pattern layer having a pattern corresponding to the desired decorative pattern is provided between the transparent resin layer and the light reflection layer, and a pattern layer is formed between the transparent resin layer having the planar upper surface portion and the light reflection layer. A first laminated portion that is laminated, a second laminated portion in which a pattern layer is not laminated between the transparent resin layer having the planar upper surface portion and the light reflecting layer,
A third laminated portion in which a pattern layer is laminated between the transparent resin layer having the concave-convex pattern upper surface portion and the light reflecting layer; and a pattern layer between the transparent resin layer having the concave-convex pattern upper surface portion and the light reflecting layer. The desired decorative pattern is formed by selective combination with the fourth stacked portion that is not stacked.

As a material constituting each of the above-mentioned layers, for example, paper, cloth or nonwoven fabric is suitably used for the base layer, and acrylic resin is preferably used for the picture layer, for example. On the other hand, for the transparent resin layer, for example, acrylic-
An ink obtained by mixing an isocyanate curing agent with a base resin obtained by adding a cellulose resin to a urethane resin is preferably used.
In general, a metal material such as aluminum is preferably used for the light reflection layer, but a reflective pigment such as gold ink or silver ink can also be used.

In the above structure, it is preferable to provide a protective layer having high heat resistance and abrasion resistance, such as a stretched polyester, a stretched polypropylene, a stretched nylon, a stretched polystyrene, a cellophane, and a polycarbonate, on the transparent resin layer. External light that has passed through the transparent resin layer is reflected by the mirror surface of the light reflecting layer, whereby the external light can be reflected with a sufficient amount of reflected light. Also, of the external light that has passed through the transparent resin layer, the external light that has been reflected by the light reflecting layer and has passed through the upper surface of the uneven pattern formed along the upper surface of the transparent resin layer is refracted by the upper surface of the uneven pattern. Thus, a reflected light pattern having a pattern corresponding to the uneven pattern can be formed on the sheet surface. Further, of the incident external light, the external light transmitted through the picture layer after being reflected by the light reflection layer is reflected light colored in accordance with the pattern of the picture layer, thereby providing a design. The effect is very good.

Further, according to the above configuration, the following four types of reflected light are formed. That is, in the first laminated portion, the incident external light is reflected by the mirror surface of the light reflection layer and then passes through the colored picture portion of the picture layer, so that monochromatic colored reflected light is obtained. In the second laminated portion, the incident external light is reflected by the mirror surface of the light reflecting layer, and monotonous achromatic reflected light is obtained. In the third laminated portion, the incident external light is reflected by the mirror surface of the light reflecting layer and then passes through the colored picture portion of the picture layer, and thereafter, the reflected light further travels along the upper surface of the transparent resin layer. When passing through the upper surface of the uneven pattern formed as described above, colored reflected light having a pattern corresponding to the uneven pattern on the upper surface of the uneven pattern is obtained. In the fourth laminated section, as in the third laminated section, the incident external light reaches the upper surface of the concavo-convex pattern formed along the upper surface of the transparent resin layer after being reflected by the light reflecting layer, where it is refracted. Then, reflected light having a pattern corresponding to the uneven pattern on the upper surface of the uneven pattern is obtained. However, these reflected lights are achromatic because they do not pass through the picture layer.
