Title (EN) ADHESIVE SHEET
(FR) FEUILLE ADHÉSIVE
(JA) 粘着シート
Abstract:
(EN) Provided is an adhesive sheet capable of suitably preventing the occurrence of air bubbles caused by outgas. According to the present invention, there is provided an adhesive sheet including an adhesive layer that constitutes adhesive surface. The adhesive sheet has a post-time lapse non-bonding area ratio Sa of 5%, the post-time lapse non-bonding area ratio Sa being defined as the proportion of the total area of non-bonding parts in the entire area of the adhesive surface relative to the glass plate after a time lapse test in which the adhesive surface is pressed onto the glass plate and held for 24 hours at 50°C. The non-bonding parts have portions that extend in linear form along the adhesive surface.
(FR) L'invention concerne une feuille adhésive pouvant empêcher de manière appropriée l'apparition de bulles d'air provoquées par un dégazage. Selon la présente invention, une feuille adhésive comprend une couche adhésive qui constitue une surface adhésive. La feuille adhésive présente un rapport d'aires non collantes Sa après un intervalle de temps de 5 %, le rapport d'aires non collantes Sa après un intervalle de temps étant défini comme la proportion de l'aire totale de parties non collantes dans l'aire entière de la surface adhésive par rapport à la plaque de verre après un test d'intervalle de temps dans lequel la surface adhésive est pressée sur la plaque de verre et maintenue pendant 24 heures à 50°C. Les parties non collantes présentent des sections qui s'étendent sous une forme linéaire le long de la surface adhésive.
(JA) アウトガスに起因する気泡の発生を好適に防止し得る粘着シートを提供する。本発明によると、粘着面を構成する粘着剤層を含む粘着シートが提供される。上記粘着シートは、上記粘着面をガラス板に圧着して50℃で24時間保持する経時試験後において、上記粘着面の全面積のうち上記ガラス板に対する非密着部の合計面積の割合として定義される経時後非密着面積率Saが5%以上である。上記非密着部は、上記粘着面に沿って線状に延びる部分を有する。
