関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to sheets and films having a printed surface that can be detachably attached to the surface of any object by electrostatic attraction.

いる。(Prior Art) Conventionally, certain types of synthetic resin materials such as vinyl chloride films and sheets can have electrostatic adsorption force, and this electrostatic adsorption force has been used to utilize 1. Attempts have been made to attach films and sheets to arbitrary objects such as paper mounts.

着力の持続性が乏しく数時間以内の比較的短時間に被付
着物体から剥離して米る欠点があった。These synthetic resin films and sheets with electrostatic adhesion are used as holder materials for holding photographs and documents, advertisements with letters and patterns printed on them, promotions, or caution and warning documents, and are used as mounts, walls, etc. It is used by adhering to the surface of any object such as glass, but when the surface of the film is printed, the adhesion strength is poorer than that of non-printed films and can last for several hours. It has the disadvantage that it peels off from the object to which it is attached in a relatively short period of time.

解明されていなかったのである。By the way, when using a conventional electrostatic adsorption film, under what conditions and how does the electrostatic force act?
This has not been reported either theoretically or experimentally. Therefore, the reason why the electrostatic adhesive force of the printed films disappears in a short time has not been completely elucidated.

静電気付着力が短時間に消失する原因を解明したのであ
る。(Problems to be Solved by the Invention) Therefore, the present inventor conducted tests and experiments to investigate the cause of the generation of the reduced static electricity force in static electricity adsorption films. They discovered the cause of their disappearance.

乗的に作用する結果、印刷を施したフィルム類の静電気
付着力が短時間に消失することを見出したのである。In other words, since the printing ink layer formed on the surface of the film or sheet acts as an electrical conductor, the electrostatic adhesion force at the periphery of the film is weak.
In addition, due to the viscoelastic deformation of the film, a minute peeling gap is generated at the periphery of the film, resulting in cracking.As a result of these two causes acting synergistically, the electrostatic adhesion of the printed film is reduced in a short period of time. I discovered that it disappears.

のである。Based on the clarification of this cause, this invention maintains the electrostatic adhesive force of printed films for a long period of time without disappearing in a short period of time, and allows the film to be attached to the surface of any object. The aim is to achieve stable adsorption.

。(Function) When a layer of printing ink is formed up to the edge of the film,
The lines of electric force of static electricity charged on the film (1) pass through the printing ink layer (2), which is a conductor, and concentrate at the edge as shown in Figure 6, and the lines of opposite polarity act from the side of the mount (4). The charges move on the outer edge surface of the film (1), and the surface of the film acts as a resistance to charges of opposite polarity. On the other hand, in this invention, as shown in FIG. Since the charge of opposite polarity flows into the film (1) from the side of the backing paper (4) through the non-printing area (1) to the backing paper (4), most of it also flows inside the film (1), and the film (1)
The volume of the film acts as a resistance to charges of opposite polarity towards the . The difference between the surface resistance and volume resistance is
This is effective in reducing electrostatic force due to charges of opposite polarity, and the film of the present invention exhibits less reduction in electrostatic force.

出来ない。Next, the film undergoes viscoelastic changes under the influence of outside temperature, humidity, light, etc., and an extremely small peel gap is generated at the periphery of the film. The minute separation space has a strong interfacial effect, so it increases conductivity, forms an inflow and accumulation point for charges of opposite polarity, and reduces electrostatic force. Therefore, when peeling occurs, rheological changes concentrate there, repeating the above phenomenon and promoting the progress of peeling. By the way, when an electrostatic force acts inside the film periphery as in the case of the film shown in FIG. When the electric force acts on the outside of the periphery of the film as shown in the figure, it does not have the effect of adhering the periphery of the film to the mount, and it is not possible to suppress the occurrence of minute separation gaps.

フィルム等である。The electrostatic adhesion sheet (1) is made of a plastic film or sheet that has a durable electrostatic adhesion that can maintain stable electrostatic adhesion over a long period of time. As a plastic film or sheet having such a sustained electrostatic adhesive force, the present inventor previously disclosed a patent application in 1985-1385.
The proposal in No. 37 can be cited as an example. These films are, for example, a vinyl chloride film containing 0.01 to 8% by weight of at least one of medium molecular weight organic ketones, amines, nitro derivatives, silicon oxide, and metal oxides, or polyvinyl chloride resin 1 00 parts, an organotin stabilizer of 3 parts or less in terms of metal tin and a lubricant in an amount that does not cause water-resistant whitening even when immersed in water at 30"C or less. Polyvinyl chloride film etc.

分散し樹脂内における電荷の分散能を良好にする性能を
有している。Vinyl chloride films, etc., which have this persistent electrostatic adhesion, have a remarkable ability to trap charges, and promote the penetration and diffusion of charges.
A unidirectional charge transfer layer is formed on the film surface, especially the friction surface of the film, so that static electricity persists for a long time, and it has the ability to uniformly disperse charge within the volume and improve charge dispersion within the resin. .
一般に多量の電荷をフィルム、シート類が保有し得るた
めには、電荷はフィルム、シート類の表面だけに存在す
ることなく、その内部にまで拡散することが望ましい。Generally, in order for a film or sheet to retain a large amount of charge, it is desirable that the charge not only exist on the surface of the film or sheet but also diffuse into its interior.

れもない。Further, in order to prevent static electricity from decreasing over time, it is desirable that the charges be trapped by the film or sheet material. In other words, if the quantity of electricity is easy to penetrate and diffuse into the volume and is trapped at the diffusion position, the electric charge per unit weight is The amount increases, and because it penetrates and diffuses into the volume, the distribution state when viewed from the surface is closer to a uniform state than in the conventional case where only the surface is charged. Furthermore, since the charges trapped within the volume are in a kind of electret state, there is no fear that they will decrease over time.

性を有するものでなければならない。Therefore, if a promoter that promotes the infiltration and diffusion of charges into the interior and a charge trapping material that prevents the charges that have penetrated and diffused into the interior from leaking out again and thereby reduce the charges are mixed with vinyl chloride resin, It is possible to produce films and sheets that have a much better sustained electrostatic adhesion than conventional ones. However, since a material that promotes the infiltration and diffusion of charges into the interior naturally also promotes the leaching and diffusion from the interior to the exterior, it does not provide long-term electrostatic adhesion. From this point of view, the material must be unidirectional, that is, a material that promotes intrusion diffusion similar to a rectification effect, but has a small percolation and diffusion ability, and has an excellent charge trapping ability. Expressed equivalently in terms of an electric circuit, the charges trapped inside form a capacitor across the adhesive surface.
The insulation resistance used as a capacitor must have rectifying resistance characteristics.

とする。In the case of printing patterns, characters, etc. on the surface of such persistent electrostatic adsorption films, the present invention provides for forming a non-printing area (Z) with a predetermined width at the periphery of the film as shown in FIG. It is characterized by The width of the non-printing area (f) is at least 10 or more, preferably 211R or more.

大部分がフィルム（１）の周縁内部を通って台紙（４）
に向かう。When a persistent electrostatic adsorption film or sheet is attached to a mount (4), it shows a distribution of electric lines of force (3) as shown in Figure 4, and when the entire film is equally charged, the lines of electric force ( 3) is concentrated at the periphery of the printing ink layer (2), and most of it passes through the inside of the periphery of the film (1) and reaches the backing paper (4).
Head to.

電気力線はフィルムの周縁外部に集中して来る。かかる
周縁部において電気力線がフィルムの内部を通るか外部
を通るかの相違が、静電気力の持続性に重大な相違をも
たらす。In contrast, with conventional film, as shown in Figure 6,
The electric lines of force are concentrated outside the periphery of the film. The difference in whether the electric lines of force pass through the inside or outside of the film at the periphery makes a significant difference in the persistence of the electrostatic force.
すなわち、第４図の場合には、電気力線の作用によって

くはフィルムの周縁内部を流れる。That is, in the case of FIG. 4, most of the charges of opposite polarity flowing into the film from the mount side flow inside the periphery of the film due to the action of electric lines of force.
これに対し、第６図の場合には、反対極性の電荷は、フ
ィルムの周縁外表面を移動することとなる。In contrast, in the case of FIG. 6, charges of opposite polarity move along the outer peripheral surface of the film.

しく抑制されるのである。In other words, in the case of Figure 4, the volume of the film acts as a resistance against charges of opposite polarity flowing into the inside of the film, whereas in Figure 6, the surface of the film only acts as a resistance. This difference between the volume resistivity and the surface resistance is effective in reducing the electrostatic force due to charges of opposite polarity, and in the film of the present invention, the reduction in the electrostatic force is significantly suppressed.

は初期剥離の売時時間が全く異なるのである。Such a minute separation space has a strong interfacial effect, increases conductivity, forms an inflow and accumulation point for charges of opposite polarity, and reduces electrostatic force. Therefore, when peeling occurs, rheological changes concentrate there, and the above phenomenon is repeated, promoting the progress of peeling. By the way, when electrostatic force acts on the inner side of the film periphery as in the case of the film shown in Fig. 4, the periphery of the film is attached to the mount by electric force, whereas the 6th
When the electric force acts on the outer peripheral surface of the film as shown in the figure, it does not have the effect of adhering the inner peripheral edge of the film to the backing paper. Thus, in the case of Fig. 6, there is an effect of suppressing minute peeling gaps, whereas in the case of the film in Fig. 5, this effect cannot be expected, and between the two films, the selling time of initial peeling is short. are completely different.
