    • An antistatic agent comprising a water-soluble electroconductive polymer comprising at least a repeating unit having a sulfo group-containing isothianaphthenylene structure; a method for suppressing electrification of an article during the production or use of the article by forming an electroconductive film comprising the water-soluble electroconductive polymer on the article; an article of which electrification is suppressed by having an electroconductive film comprising the water-soluble conductive polymer on the article; and a method for observing or inspecting an article with suppressing electrification thereof during irradiation with charged particle beams by forming an electroconductive film comprising the water-soluble electroconductive polymer on the article. The electroconductive film retains the electrification-suppressing effect and removability stably even when subjected to a heat treatment or left to stand for a long period of time. The antistatic agent can be formulated into a film-forming antistatic composition which can be used at any pH value from acidic to basic and which is excellent in storage stability.
    • 一种抗静电剂,其包含至少包含具有含磺基的异硫茚结构的重复单元的水溶性导电聚合物; 一种通过在制品上形成包含水溶性导电聚合物的导电膜来抑制在制造或使用制品期间物品带电的方法; 通过在制品上具有包含水溶性导电聚合物的导电膜来抑制带电的制品; 以及通过在制品上形成包含水溶性导电聚合物的导电膜,在带电粒子束照射期间观察或检查物品的带电抑制方法。 导电膜即使经受热处理也可以稳定地保持电气抑制效果和可移除性,或者长时间静置。 抗静电剂可以配制成成膜抗静电组合物,其可以在酸性至碱性的任何pH值下使用,并且储存稳定性优异。
