である。(Working) When a layer of printing ink is formed up to the edges of films,
Electrostatic lines of force charged in the film (1) pass through the printing ink layer (2), which is a conductor, are concentrated at the edges as shown in FIG. 6, and have opposite polarities acting from the side of the mount (4). Of electric charges move on the outer surface of the end of the film (1), and the surface of the film acts as a resistance against electric charges of opposite polarity. On the other hand, in the present invention, as shown in FIG. 4, the electric lines of force (3) concentrated at the end of the printing ink (2) are mostly formed on the entire periphery of the film (1). Since it goes toward the mount (4) through the non-printed area (l), the mount (4)
Most of the opposite polarity charges flowing into the film (1) from the side of the flow also flow inside the film (1), and the volume of the film acts as a resistance against the opposite polarity charges toward the film (1). . The difference between the surface resistance and the volume resistance exerts an effect of reducing the electrostatic force due to the opposite polarity charges, and the film of the present invention reduces the reduction of the electrostatic force.

長期に亘って安定に維持することが出来るのである。Next, the film undergoes a viscoelastic change under the influence of outside air temperature, humidity, light rays, etc., and an extremely minute peeling gap is generated at the periphery of the film. Since the minute separation space has a strong interfacial action, it increases conductivity, forms an inflow accumulation point of opposite polarity charge, and reduces electrostatic force. Therefore, once peeling occurs, rheological changes concentrate there, and the above phenomenon is repeated to promote the progress of peeling. By the way, when the electrostatic force acts on the inside of the entire peripheral edge of the film as in the film of FIG. 4, the entire peripheral edge of the film is attached to the mount by the electrostatic force to control the generation of the minute peeling gap due to the viscoelastic change. On the other hand, when an electric force acts on the outside of the peripheral edge of the film as shown in FIG. 6, it has no effect of adhering the peripheral edge of the film to the mount and it is not possible to control the generation of the minute peeling gap. Thus, in the case of the present invention, it is possible to maintain the adhesive force of the film stable for a long period of time by controlling the reduction of the electrostatic force and the generation of the minute peeling gap by the entire peripheral edge of the film (1) and the non-printing area. Of.

Incidentally, FIG. 1 (A) shows a conventional electrostatic attraction sheet.

い範囲で配合したポリ塩化ビニルフィルム等である。The electrostatic adsorption sheet (1) is made of a plastic film or sheet having a persistent electrostatic adhesion force capable of maintaining a stable electrostatic adsorption force for a long period of time. As the plastic film or sheet having such a persistent electrostatic adhesive force, the one previously proposed by the present inventor in Japanese Patent Application No. 56-138537 can be mentioned as an example. The films are, for example, medium molecular weight organic ketones, amines,
A vinyl chloride film containing 0.01 to 8% by weight of at least one of a nitro derivative, silicon oxide and a metal oxide,
Or, with respect to 100 parts of polyvinyl chloride resin, 3 parts or less of organotin stabilizer in terms of metal tin and 30 parts or more of lubricant and other compounding agents are used.
It is a polyvinyl chloride film or the like blended in a range that does not cause a water whitening resistance even when immersed in water at a temperature of not higher than 0 ° C.

有している。Vinyl chloride film, etc., which has this persistent electrostatic adhesive force, has a remarkable charge-capturing ability, and promotes the penetration and diffusion of charges.
A unidirectional charge transfer layer is formed on the film surface, especially the friction surface of the film, and static electricity is maintained for a long time, and the charge is evenly dispersed in the volume and the ability to disperse the charge in the resin is good. .

恐れもない。In general, in order that a large amount of electric charge can be retained in a film or sheet, it is desirable that the electric charge is not present only on the surface of the film or sheet, but diffuses into the inside thereof.
Further, in order that the static electricity does not decrease with time, it is desirable that the charges are trapped by the film or sheet material. That is, if the amount of electricity easily diffuses into the volume and is trapped at the diffusion point, the electric charge is present not only on the surface but also in the volume as compared with the conventional one, so that the unit weight per unit weight The amount of electricity becomes large, and the distribution state when viewed from the surface approaches the state closer to uniform compared to the conventional surface-only charging because it diffuses into the volume and diffuses. In addition, since the electric charge trapped in the volume is a kind of electret state, there is no fear that it will decrease with time.

抗特性を有するものでなければならない。Therefore, if a promoter that promotes invasion and diffusion of electric charges into the interior and a charge trapping material that prevents the electric charges that infiltrate and diffuse into the interior from leaching to the outside again are mixed with the vinyl chloride resin, It is possible to manufacture films and sheets having a far superior electrostatic adhesion force than conventional ones. However, a material that promotes invasion and diffusion of electric charges into the interior also promotes leaching and diffusion from the inside to the outside, so that it does not provide long-term electrostatic adhesion. From this point of view, the material has to be a material that promotes invasion and diffusion similar to unidirectionality, that is, rectification, but has a small leaching and diffusing ability and an excellent charge trapping ability. In terms of electrical circuit equivalent expression, the charge trapped inside should form a capacitor with the attachment surface separated, and the insulation resistance as the capacitor should have a rectifying resistance characteristic.

静電気付着力を示すのである。The vinyl chloride film exhibits such charge trapping ability, charge intrusion and diffusion ability into the interior, and rectifying resistance characteristics very remarkably, and exhibits stable and persistent electrostatic adhesive force for a long period of time.

する。According to the present invention, when a pattern, a character or the like is printed on the surface of such a persistent electrostatic adsorption film, a non-printed area (l) is formed on the entire periphery of the film with a predetermined width as shown in FIG. It is characterized by having done. The non-printing area (l)
Has a width of at least 1 mm or more, preferably 2 mm or more.

（４）に向かう。When the persistent electrostatic adsorption film or sheet is attached to the mount (4), it shows a distribution of electric force lines (3) as shown in FIG. 3) is concentrated on the entire peripheral edge of the printing ink layer (2), and most of it goes through the inside of the entire peripheral edge of the film (1) toward the mount (4).

The lines of electric force are concentrated outside the periphery of the film. The difference between the lines of electric force passing through the inside or the outside of the film at the peripheral portion causes a significant difference in the persistence of electrostatic force.

っては、静電気力の減少が著しく抑制されるのである。That is, in the case of FIG. 4, most of the charges of opposite polarities flowing into the film from the mount side flow inside the entire peripheral edge of the film due to the action of the lines of electric force. On the other hand, in the case of FIG. 6, electric charges of opposite polarities move on the outer peripheral surface of the film. That is, in the case of FIG. 4, the volume of the film acts as a resistance against the electric charges of opposite polarity flowing into the inside of the film, whereas in FIG. 6, the surface of the film merely acts as a resistance. The difference between the volume resistance and the surface resistance exerts an effect of reducing the electrostatic force due to the opposite polarity charges, and in the film of the present invention, the reduction of the electrostatic force is significantly suppressed.

剥離の発時時間が全く異なるのである。Further, the film is constantly affected by outside air temperature, humidity, light rays and the like to viscoelastically change, and an extremely minute peeling gap is generated at the periphery of the film. Since such a minute separation space has a strong interfacial action, it increases conductivity, forms an inflow accumulation point of opposite polarity charges, and reduces electrostatic force. Therefore, once peeling occurs, rheological changes are concentrated there, and the reduction is repeated to promote the progress of peeling. By the way, when an electrostatic force is applied to the inside of the entire peripheral edge of the film as in the case of the film of FIG. 4, the entire peripheral edge of the film is attached to the mount by an electric force, whereas the peripheral edge of the film is as shown in FIG. When an electric force acts on the outer surface, it does not have the effect of adhering the inside of the film periphery to the mount. Thus, in the case of FIG. 4, there is an effect of suppressing the minute peeling gap, whereas the effect cannot be expected in the film of FIG. 6, and the initial peeling time between the two films cannot be expected. Is completely different.
非印刷領域（ｌ）の幅は、第５図に示すように2mm以上

であれば1mm程度でも充分であろう。The width of the non-printing area (1) is preferably 2 mm or more as shown in FIG. However, if it is used for several days, about 1 mm may be sufficient.
