The present invention relates to a certain above decorative sheet.

Decorative sheets made of synthetic resin are widely used as surface materials for furniture, vehicles, electrical products, footwear, bags, etc.

Backing material 1 made of a sheet material made of non-woven fabric, woven fabric, knitted fabric, etc. made of glass fiber, synthetic fiber, natural fiber, etc. coated or impregnated with synthetic resin, or a synthetic resin sheet material, etc.
A decorative layer 2 has been developed in which synthetic resin particles (chips) 10 are scattered and fixed thereon to form a fine mosaic pattern using the chips 10.

Some are used as flooring and wall materials to prevent problems caused by static electricity (such as explosions, dust accumulation, computer malfunctions, etc.).

【発明が解決しようとする課題】ところで、最近の生活
様式の多様化から、前述の微小モザイク状模様の装飾層
２を有する装飾シートにおいても、デザインを多様化す
る要請から生じて来ている。However, with the recent diversification of lifestyles, there has been a demand for diversifying the designs of decorative sheets having the decorative layer 2 having the aforementioned micro-mosaic pattern.
【０００６】しかし、従来の微小モザイク状模様は、バ
ッキング材１の全面を覆って形成されていることから、
全面を単調なモザイク状模様とする以外のデザインは望
み得ない。However, since the conventional micro mosaic pattern is formed covering the entire surface of the backing material 1,
No other design than a monotonous mosaic pattern can be desired over the entire surface.
【０００７】また、該模様の装飾シートを導電性シート

要である。従って、表面に位置する合成樹脂製チップ１
０にも導電性材料を混入させておく必要がある。[0007] Furthermore, in the case where the patterned decorative sheet is an electrically conductive sheet, it is necessary that electrical conductivity be established from the surface of the mosaic pattern layer 2 to the back surface of the backing material 1. Therefore, the synthetic resin chip 1 located on the surface
It is also necessary to mix a conductive material into the 0.
【０００８】この導電性材料としては、従来、カーボン
ブラックを使用するのが一般的であることから、この種
の導電性装飾シートは、全面が黒灰色ないしは黒色を帯
び、装飾性が完全に没却されていた。Since carbon black has conventionally been commonly used as the conductive material, this type of conductive decorative sheet has a blackish-gray or black color on its entire surface, and has completely lost its decorative properties. It had been rejected.

を形成する技術が開発さている。As a countermeasure to this problem, the mosaic pattern described above has been created by using a mixture of synthetic resin chips mixed with carbon black and synthetic resin chips that can be colored as desired using a light-colored conductive material. A mosaic pattern can be created using layer forming technology (Japanese Unexamined Patent Publication No. 63-112777) or by forming a surface layer of a colored thermoplastic resin containing a light-colored conductive material on the surface of colored synthetic resin particles. Techniques for forming layers have been developed.

雑である。However, in the former case, in addition to the need to prepare two types of chips, conduction from the sheet surface to the backing material is ensured only by the conductive material mixed in the chip. This requires advanced mixing technology (requiring mixing in a completely uniform state and strict adjustment of the mixing amount), and the sheet manufacturing process is complicated.

になる懸念がある。[0011] In the latter case, although sufficient electrical conductivity from the sheet surface to the backing material is ensured, there is a concern that the manufacturing process will become complicated due to the addition of the step of forming a surface layer of synthetic resin particles.
