Title (EN) PRESSURE-SENSITIVE ADHESIVE SHEET
(FR) FEUILLE ADHÉSIVE SENSIBLE À LA PRESSION
(JA) 粘着シート
Abstract:
(EN) Provided is a pressure-sensitive adhesive sheet which has excellent shear performance and improved low-temperature resilience resistance. The present invention provides a pressure-sensitive adhesive sheet which includes a pressure-sensitive adhesive layer comprising a base polymer and at least one tackifier resin. The base polymer is a block copolymer of a monovinylaromatic compound with a conjugated diene compound. The content of the tackifier resin is 10-60 parts by weight per 100 parts by weight of the base polymer. The tackifier resin comprises a tackifier resin TH having a softening point of 100ºC or higher. The content of the tackifier resin TH is at least 10 parts by weight per 100 parts by weight of the base polymer. The pressure-sensitive adhesive layer has a tacky surface which has, in a ball tack test in a 0ºC environment, a tackiness property in terms of ball number of 4 or greater.
(FR) L'invention concerne une feuille adhésive sensible à la pression qui présente une excellente performance de cisaillement et une meilleure résistance à la résilience à basse température. La présente invention concerne une feuille adhésive sensible à la pression qui comporte une couche adhésive sensible à la pression comprenant un polymère de base et au moins une résine agent poisseux. Le polymère de base est un copolymère séquencé d'un composé monovinylaromatique avec un composé diène conjugué. La teneur de la résine d'agent poisseux est de 10 à 60 parties en poids pour 100 parties en poids du polymère de base. La résine d'agent poisseux comprend une résine d'agent poisseux TH ayant un point de ramollissement de 100 °C ou plus. La teneur de la résine d'agent poisseux TH est au moins de 10 parties en poids pour 100 parties en poids du polymère de base. La couche adhésive sensible à la pression a une surface collante qui présente, dans un test d'adhésivité de bille dans un environnement à 0 °C, une propriété d'adhésivité en termes de nombre de billes de 4 ou plus.
(JA) 優れたせん断性能を有し、かつ低温耐反撥性が改善された粘着シートを提供する。 本発明により、ベースポリマーと粘着付与樹脂とを含有する粘着剤層を備える粘着シートが提供される。前記ベースポリマーは、モノビニル置換芳香族化合物と共役ジエン化合物とのブロック共重合体である。また、前記粘着付与樹脂の含有量は、前記ベースポリマー100重量部に対して10~60重量部である。また、前記粘着付与樹脂は、100℃以上の軟化点を有する粘着付与樹脂Tを含む。さらに、前記粘着付与樹脂Tの含有量は、前記ベースポリマー100重量部に対して10重量部以上である。そして、前記粘着剤層の粘着面は、0℃環境下でのボールタック試験においてボールナンバー4以上の特性を有する。
