て使用される。Conventionally, pressure-sensitive adhesive sheets are known that have a structure in which a release paper coated with a release agent such as silicone is coated with an adhesive on the surface of the release agent layer, and a surface sheet such as paper is bonded on top of the release agent layer. There is. For such pressure-sensitive adhesive sheets, the release paper is peeled off to obtain a surface sheet with an exposed adhesive layer, and this is attached to a desired solid surface using the adhesive properties of the adhesive layer. used.

にわたって安定的に吸着させることができない。By the way, in the pressure-sensitive adhesive sheet that is commonly used in the past, since it is attached to a solid surface through an adhesive layer, once it is attached to a solid surface, it cannot be peeled off. Therefore, it is difficult to reattach it to another location or other solid surface, and there is also the disadvantage that some of the adhesive remains on the peeled trace of the solid surface and contaminates the solid surface. Ta. On the other hand, in order to improve this drawback, a highly charged plastic film coated with a release agent is used in place of the release paper, and the electrostatic attraction is used to adsorb it to the solid surface. A pressure-sensitive adhesive sheet has also been proposed (Utility Model Publication No. 52-1138)
However, in this case, the electrostatic attraction force of the plastic film is weak and the sustainability of the electrostatic attraction force is poor, so it cannot be stably attached to a solid surface for a long period of time. It cannot be adsorbed.
