Title (EN) ADHESIVE TAPE
(FR) RUBAN ADHÉSIF
(JA) 粘着テープ
Abstract:
(EN) Provided is an adhesive tape formed integrally by co-extruding a base layer, a rear treatment layer formed on one surface of the base layer, and an adhesive layer formed on the other surface of the base layer, said adhesive tape having exceptional weather resistance, particularly when the adhesive layer is mainly composed of a synthetic rubber, exhibiting excellent rewind properties, suppressing contamination of the adhesive layer surface, and having excellent adhesion strength. This adhesive tape is formed integrally by co-extruding a base layer, a rear treatment layer formed on one surface of the base layer, and an adhesive layer formed on the other surface of the base layer. The base layer contains at least a whitish layer and a blackish layer. The rear treatment layer comprises a composition including an anti-oxidant and a rear treatment agent comprising a reaction product of a hydroxyl-containing polyvinyl polymer and a long-chain alkyl isocyanate compound, and said rear treatment layer has a thickness of 40 μm or less.
(FR) L'invention concerne un ruban adhésif formé intégralement par co-extrusion d'une couche de base, et une couche de traitement arrière formée sur une surface de la couche de base et d'une couche adhésive formée sur l'autre surface de la couche de base, ledit ruban adhésif ayant une exceptionnelle résistance aux intempéries, en particulier quand la couche adhésive est principalement composé d'un caoutchouc synthétique, présentant d'excellentes propriétés de rebobinage, supprimant la contamination de la surface de couche adhésive et ayant un excellent pouvoir adhérent. Ce ruban adhésif est formé intégralement par co-extrusion d'une couche de base, d'une couche de traitement arrière formée sur une surface de la couche de base et d'une couche adhésive formée sur l'autre surface de la couche de base. La couche de base contient au moins une couche blanchâtre et une couche noirâtre. La couche de traitement arrière comprend une composition comprenant un antioxydant et un agent de traitement arrière comprenant un produit de réaction d'un polymère polyvinylique à teneur en hydroxyle et un composé isocyanate d'alkyle à longue chaîne, et ladite couche de traitement arrière a une épaisseur de 40 µm ou moins .
(JA)  基材層、該基材層の片面に形成された背面処理層、および該基材層のもう一方の片面に形成された粘着層が共押出成形により一体に形成されてなる粘着テープであって、特に、粘着層が合成ゴムを主成分とする場合にも、耐候性に非常に優れ、優れた巻き戻し性を示し、粘着層表面の汚染が抑制され、粘着強度に優れる、粘着テープを提供する。 本発明の粘着テープは、基材層、該基材層の片面に形成された背面処理層、および該基材層のもう一方の片面に形成された粘着層が共押出成形により一体に形成されてなる粘着テープであって、該基材層が、白色系層および黒色系層の2層を少なくとも含み、該背面処理層が、活性水酸基含有ポリビニル重合体と長鎖アルキルイソシアネート化合物との反応生成物からなる背面処理剤および酸化防止剤を含む組成物からなり、該背面処理層の厚さが40μm以下である。
