Abstract
(EN)
Provided is an adhesive sheet which has anti-metal corrosion properties and can therefore be used even on a metal adherend and which can also prevent or inhibit contamination of the surface of the adherend while maintaining good removability even when adhered to the adherend for a long period of time. An adhesive sheet which includes an adhesive layer is provided. The adhesive layer contains a base polymer at a proportion of at least 95% by weight. Moreover, the chloride ion content as measured by hot water extraction is less than 300μg per gram of the adhesive layer.
(FR)
L'invention concerne une feuille adhésive qui présente des propriétés anticorrosion métallique et peut donc être utilisée même sur une partie à coller métallique et qui peut également empêcher ou inhiber une contamination de la surface de la partie à coller tout en conservant une bonne aptitude à l'enlèvement même lorsqu'elle est collée à la partie à coller pendant une longue période de temps. L'invention concerne également une feuille adhésive comprenant une couche adhésive. La couche adhésive contient un polymère de base dans une proportion d'au moins 95 % en poids. De plus, la teneur en ions chlorure telle que mesurée par extraction à l'eau chaude est inférieure à 300 μg par gramme de la couche adhésive.
(JA)
金属腐食防止性を有するので金属製の被着体にも利用することができ、かつ、前記被着体に長期にわたって貼り付けられた場合であっても被着体表面の汚染を防止または抑制しつつ良好な剥離性を維持し得る粘着シートを提供する。粘着剤層を備える粘着シートが提供される。前記粘着剤層は、ベースポリマーを95重量%以上の割合で含む。また、熱水抽出により測定される塩化物イオン量が前記粘着剤層1g当たり300μg未満である。
