Description

従来、プラスチック等の絶縁性物質、或いは紫外線硬化型ハードコート等のコーティング分野において、クリアタイプに使用できる、且つ低添加量で優れた帯電防止能を有する帯電防止剤の開発が望まれている。クリアタイプに使用できるものとしては数々の異なるタイプの帯電防止剤が提案されている。なかでも、フッ素系界面活性剤型帯電防止剤は、パーフルオロ基の強い表面移行性から、ごく少量で高い帯電防止能が得られることが期待される。特に、ノニオン構造を有するフッ素系界面活性剤型帯電防止剤は、カチオン型やアニオン型またベタイン型と比較して、水溶解性のみならず、溶剤或いは樹脂などへも使用できるといった利点があった。このようなものとしては、これまでにパーフルオロアルキル基含有アミンＮ−オキサイド化合物が提案されている（例えば、特許文献１、２参照。）。 Conventionally, development of an antistatic agent that can be used in a clear type and has an excellent antistatic ability with a low addition amount has been desired in the coating field such as an insulating material such as plastic or an ultraviolet curable hard coat. Many different types of antistatic agents have been proposed for use in the clear type. Among these, a fluorosurfactant type antistatic agent is expected to have a high antistatic ability even in a very small amount due to the strong surface migration of the perfluoro group. In particular, the fluorosurfactant type antistatic agent having a nonionic structure has an advantage that it can be used not only for water solubility but also for a solvent or a resin as compared with a cationic type, an anionic type or a betaine type. . As such, perfluoroalkyl group-containing amine N-oxide compounds have been proposed so far (see , for example , Patent Documents 1 and 2).

Claims
