As the abrasion-chargeable plastic film, a conventionally known plastic film having a high insulating property is used. Specific examples thereof include a polyvinyl chloride film, a vinylidene chloride resin film, a polystyrene film, Examples include fluorine-containing ethylene, propylene copolymer film, and polypropylene film. Electretized plastic film can be obtained by applying a high voltage to a plastic film by corona discharge using a conventional method, and can retain electric charge semipermanently. It is a plastic film that can be used for both. Compared to the above-mentioned triboelectric plastic film, which tends to attenuate the electrostatic attraction force, Retretted plastic film is a plastic film that has much better charge retention and stability, and is less likely to attenuate the electrostatic attraction force. Vinylidene film, fluorinated polyethylene, propylene copolymer film, polypropylene propylene film, polyester film, polymethylpentene film, etc., and highly charged plastic films such as polyvinyl chloride It may be an electret of the above. As the above-mentioned triboelectrically-chargeable plastic film and plastic film for electretization, those having high insulating properties which do not contain a plasticizer and an antistatic agent are preferably used. The surface resistance of these plastic films is usually at least 10 13 ohms, especially at least 10 15 ohms.
本発明で用いる表示物シー トは、 その裏面に、 台紙フィルム と剥離可能又は剥離不能に接着し得る接着剤層、 自己接着性榭 脂層又は自己接着性発泡樹脂層を裏面に有するものである。 こ の表示物シー トは、 紙、 プラスチックフィルム、 発泡シー ト、 布等であることができる。 また、 この表示物シー トの表面には、 必要に応じ、 他のフ ィ ルムを積層接着することができ、 例えば、 表示物シー トが紙の場合にはプラスチックフィルムを、 またプ ラスチックフ ィルムの場合には紙を積眉接着させることができ る。  The display sheet used in the present invention has an adhesive layer, a self-adhesive resin layer, or a self-adhesive foamed resin layer, which can be peelably or non-peelably adhered to the backing film, on the back surface thereof. . The display sheet can be paper, plastic film, foam sheet, cloth, or the like. If necessary, other films can be laminated and adhered to the surface of the display sheet.For example, when the display sheet is paper, a plastic film or plastic film can be used. In such cases, paper can be attached to the eyebrows.
本発明において用いる表示物シー トの裏面に形成する接着剤 層と しては、 台紙フィルムの静電吸着力の低下を防止するため に、 可塑剤及び軟化剤を含有しない接着剤層であることが必要 である。 本発明者の研究では、 接着剤と して一般に用いられて いるゴム系接着剤あるいはゴム系溶剤型接着剤等の可塑剤ゃ軟 化剤を含有する接着剤を裏面に塗布して形成した表示物シー ト を、 その接着剤層を介して台紙フィルムに接着させた状態で放 置すると、 約 1 0 日間程度の経過後には、 静電吸着性のある台 紙フィルムの帯電性が減少し、 静電吸着力が著しく低下するこ とが見出された。 これは接着剤中の可塑剤や軟化剤が、 静電吸 着性プラスチックフィルムの中へ移行することによ リ、 そのフ イルムに変質を生じさせ、 それがために静電吸着力の著しい低 下が生じるものと考えられる。 本発明で用いる可塑剤や軟化剤 を含まない接着剤層を有する表示物シートでは、 このような不 都合は全く生じない。 The adhesive layer formed on the back surface of the display sheet used in the present invention is an adhesive layer that does not contain a plasticizer and a softener in order to prevent a decrease in the electrostatic attraction force of the backing film. is necessary. In the research of the present inventors, it was generally used as an adhesive. A display material sheet formed by applying a plasticizer such as a rubber-based adhesive or a rubber-based solvent-type adhesive to the back surface, and bonding to a backing film via the adhesive layer When left in this state, it was found that after about 10 days had passed, the chargeability of the backing film with electrostatic attraction decreased, and the electrostatic attraction decreased significantly. This is because plasticizers and softeners in the adhesive migrate into the electrostatically adsorbable plastic film, causing the film to deteriorate, and as a result, the electrostatic attraction force is extremely low. It is considered that the following occurs. Such an inconvenience does not occur at all in a display sheet having an adhesive layer containing no plasticizer or softener used in the present invention.
本発明で用いる非可塑剤系又は非軟化剤系の接着剤は、 通常 の接着剤の他、 感圧粘着剤を包含するもので、 その接着剤眉は、 台紙フィルムに対して、 剥離性を有しもよく、 また有していな くてもよい。 このよ うな接着剤と しては、 例えば、 アク リル系 接着剤、 水系接着剤、 液状硬化型接着剤、 ポリ ウ レタ ン系接着 剤等がある。 ポリ ウレタン系粘着剤については、 例えば、 ポリ オール （例えば、 ポリエーテルポリオール） 1 0 0重量部とポ リ イ ソシァネー ト （例えばト リ レンジイ ソシァネー ト） 4 0重 量部とからなるものを混合した後、 1 0 0 ¾で、 約 1 5分間加 熱することによって得ることができる。 また、 自己接着性榭脂 層ゃ自己接着性発泡樹脂層を有する表示物シートにおいても、 同様に前記の如き不都合を生じることはない。  The non-plasticizer-based or non-softening agent-based adhesive used in the present invention includes a pressure-sensitive adhesive in addition to a normal adhesive. It may have or may not have. Examples of such an adhesive include an acrylic adhesive, an aqueous adhesive, a liquid curable adhesive, and a polyurethane adhesive. As for the polyurethane-based adhesive, for example, a mixture of 100 parts by weight of a polyol (for example, polyether polyol) and 40 parts by weight of a polyisocyanate (for example, tolylene isocyanate) is mixed. Later, it can be obtained by heating at 100 ° C. for about 15 minutes. Also, the display sheet having the self-adhesive resin layer / self-adhesive foamed resin layer does not suffer from the above-mentioned inconvenience.
自己接着性榭脂は、 榭脂自体の持つ接着力又は粘着力を利用 した再剥離性を有する接着剤でぁリ、 可塑剤や軟化剤を含まな いことから、 本発明に好ましく用いることができる。 この自己 接着性榭脂からなる接着剤と しては、 日本加工製紙（株）によ リ 商品名 「N K— O N E T A K：」 で販売されているエチレン一酢 酸ビニル共重合体系のものを好ましく用いることができる。 Self-adhesive resin is a removable adhesive that uses the adhesive or tackiness of the resin itself, and does not contain plasticizers or softeners. Therefore, it can be preferably used in the present invention. As the self-adhesive resin-based adhesive, an ethylene-vinyl acetate copolymer-based adhesive sold under the trade name “NK-ONETAK:” by Nippon Kaishi Paper Co., Ltd. is preferably used. be able to.
自己接着性発泡樹脂は、 その表面に微細孔を多数有するシー ト状発泡樹脂で、 その微細孔によ リ平滑表面に対して密着性亦 は接着性を有するものである。 このものも、 台紙フィルムを変 質させることがなく、 その静電吸着力を低下させる作用を示さ ないことから、 本発明に好ましく用いることができる。 この自 己接着性発泡榭脂と しては、 ウレタン樹脂とアク リ ル榭脂又は ブタジエン系合成ゴムとの混合物を基材樹脂と して含むものが 特開平 1 — 2 5 9 0 4 3号公報に記載されておリ、 また、 大日 本ィンキ化学工業 （株） によ リ、 商品名 「パピラル B— 0 0 1 L A」 と して販売されている。  The self-adhesive foamed resin is a sheet-shaped foamed resin having a large number of micropores on its surface, and has adhesiveness or adhesion to a smooth surface due to the micropores. This also can be preferably used in the present invention because it does not deteriorate the backing film and does not exhibit the effect of lowering the electrostatic attraction force. As the self-adhesive foamed resin, a resin containing a mixture of a urethane resin and an acrylic resin or a butadiene-based synthetic rubber as a base resin is disclosed in Japanese Patent Application Laid-Open No. 1-259430. It is described in the official gazette, and is sold by Dainichi Ink Chemical Industry Co., Ltd. under the trade name "Papiral B-001 LA".

本発明の表示用材料は、 その台紙フィルム 1が静電吸着性を 有することから、 その台紙フィルム 1を介してガラスや、 プラ スチック、 紙等の固体表面に静電吸着させることができる。 ま た、 表示物シー ト 2は、 必要に応じ、 これを台紙フィルム 1か ら剥離し、 その表示物シート 2の裏面に形成した接着剤層、 自 己接着性樹脂層又は自己接着性榭脂層 3を介して、 種々の固体 表面に接着させることができ、 さらに必要に応じ、 その固体表 面から剥離し、 台紙フィルム 1に再び接着させること もできる, 本発明の接着剤層を有する表示物シー トを用いた表示用材料 において、 台紙フィルム 1 の表示物シー ト 2を接着させる側の 表面には、 シリ コーン等の剥離剤を塗布し、 表示物シー トの台 紙フィルムからの剥離を容易なものにすることができる。 The display material of the present invention can be electrostatically adsorbed on a solid surface such as glass, plastic, or paper through the mount film 1 because the mount film 1 has an electrostatic attraction property. The display sheet 2 is peeled from the backing film 1 as necessary, and the adhesive layer, the self-adhesive resin layer or the self-adhesive resin formed on the back surface of the display sheet 2 is used. It can be adhered to various solid surfaces via layer 3 and, if necessary, its solid surface The display material using the display sheet having the adhesive layer of the present invention can be peeled off from the surface and adhered again to the backing film 1. The surface can be coated with a release agent such as silicone to facilitate the release of the display sheet from the backing film.
また、 台紙フィルム 1 と してポリ オレフイ ン系榭脂フィルムや 塩化ビュル Z酢酸ビュル共重合体フィルムを用い、 表示物シー ト 2 と して紙ゃポリ塩化ビュルフィルムを用いる時には、 前記 した剥離剤を台紙フィルム上に塗布しなくても、 表示物シー ト を容易に台紙フィルムから剥離させることができる。  When a polyolefin resin film or a vinyl chloride Z-butyl acetate copolymer film is used as the backing film 1 and a paper-polychlorinated vinyl film is used as the display sheet 2, the release agent described above is used. It is possible to easily peel off the display sheet from the backing film without applying it on the backing film.
本発明の表示用材料は、 台紙フィルムの静電吸着性を利用し て、 紙や、 プラスチック、 ガラス等の各種平滑固体表面に接着 (静電吸着） させることができる。 この場合、 その固体表面に 対する接着力は接着剤によらず、 静電吸着によるものであるこ とから、 その表示用材料の固体表面上での移動及び剥離を自在 に行う ことができ、 かつ固体表面には何らの汚染及ぴ損傷を与 えない。 また、 本発明の表示用材料においては、 必要に応じ、 その表示物シー トをその裏面に剥離可能に形成された接着剤層、 自己接着性樹脂層又は自己接着性発泡樹脂層を利用して固体表 面に強固に接着させることができる。  The display material of the present invention can be adhered (electrostatically adsorbed) to various smooth solid surfaces such as paper, plastic, and glass by utilizing the electrostatic adsorbing property of the backing film. In this case, since the adhesive force to the solid surface is not due to the adhesive but due to electrostatic attraction, the display material can be freely moved and peeled on the solid surface, and Does not cause any contamination or damage to the surface. Further, in the display material of the present invention, if necessary, the display object sheet is formed on the back surface thereof by using an adhesive layer, a self-adhesive resin layer, or a self-adhesive foamed resin layer. It can be firmly adhered to solid surfaces.
本発明の表示用材料においては、 台紙フィルム上に表示物シ ー トを、 その接着剤層、 自己接着性樹脂層又は自己接着性発泡 樹脂層を介して接着させた状態で長時間放置しても、 台紙フィ ルムの静電吸着力が急激に低下することがない。  In the display material of the present invention, the display sheet is left for a long time in a state where the display sheet is adhered to the backing film via the adhesive layer, the self-adhesive resin layer or the self-adhesive foamed resin layer. However, the electrostatic attraction force of the backing film does not suddenly decrease.
本発明の表示用材料は、 その表示物シー トに所要の文字や、 絵画、 図形、 符号等の印刷を施し、 広告媒体、 学習教材等の用 途に利用される。 The display material according to the present invention is provided with the necessary characters and It prints paintings, figures, and symbols, and is used for advertising media and learning materials.
