摘要： The present invention provides an electrostatic adsorbable sheet that can attach and display a printed material as it is on an object to be attached, as a poster, an advertisement or the like, has a high electrostatic adsorbability during display use, can be used for display over a long period of time with sufficient durability of the electrostatic adsorbability, has electrostatic adsorbability that is hardly affected by humidity, and can be easily peeled away after display use. In the electrostatic adsorbable sheet, since the electrostatic adsorbability is not exhibited externally before display use, troubles such as blocking of sheets themselves and attachment to a roll particularly in a printing step hardly occur, handlability is good, and the adhesiveness of ink is excellent, so that the sheet is compatible with a variety of printing methods. The present invention relates to an electrostatic adsorbable sheet (iii) which is a laminate comprising a label layer (i) containing a resin film layer (A) and a recording layer (B) on one surface of the resin film layer (A) and a support layer (ii), wherein at least one of the label layer (i) and the support layer (ii) is subjected to an electrically charging treatment, the resin film layer (A) and the support layer (ii) are electrostatically adsorbed, the surface resistivity of the label layer (i) side is from 1×10 -1 Ω to 9x 10 12 Ω, and the surface resistivity of the support layer (ii) side is from 1×10 -1 Ω to 9×10 12 Ω.
摘要翻译：本发明提供一种静电吸附片，该静电吸附片能够将印刷物原样附着并显示在要附着的物体上，作为海报，广告等，在显示器使用期间具有高静电吸附性，可用于显示在具有足够的静电吸附性耐久性的情况下长时间地具有几乎不受湿度影响的静电吸附性，并且在显示器使用后可以容易地剥离。在静电吸附片材中，由于在显示器使用之前静电吸附性不显示在外部，所以特别是在印刷步骤中几乎不发生片材本身的粘连和附着到辊子的问题，操作性良好，并且墨水的粘附性优异，以便纸张与各种打印方法兼容。本发明涉及一种静电吸附片（iii），其是包括在树脂膜层（A）的一个表面上包含树脂膜层（A）和记录层（B）的标签层（i）和（ii），其中标签层（i）和支撑层（ii）中的至少一个经受充电处理，树脂膜层（A）和支撑层（ii）静电吸附，标签层（i）侧的表面电阻率为1×10-1Ω至9×1012Ω，并且支撑层（ii）侧的表面电阻率为1×10-1Ω至9×1012Ω 。
