Abstract:
(EN) [Solution] Provided is an adhesive composition which contains a vinyl polymer (A) and an acrylic adhesive polymer (B), and wherein: the vinyl polymer (A) has a glass transition temperature (Tg) of from 60°C to 200°C (inclusive) and a number average molecular weight of from 500 to 10,000 (inclusive); and the vinyl polymer (A) is contained in an amount of from 0.5 part by mass to 60 parts by mass (inclusive) per 100 parts by mass of the acrylic adhesive polymer (B). If this adhesive composition is applied to a separator and then dried, thereby obtaining an adhesive layer, a first Tg that is the glass transition temperature of the entire adhesive layer is from -80°C to 10°C (inclusive), and a second Tg that is the glass transition temperature calculated from a surface layer portion of the adhesive layer as determined by X-ray photoelectron spectroscopy is 40°C or higher, and is higher than the first Tg by 30°C or more.
(FR) La présente invention concerne une composition adhésive qui contient un polymère vinylique et un polymère acrylique adhésif (B): le polymère vinylique (A) présentant une température de transition vitreuse (Tg) de 60 °C à 200 °C (inclus) et un poids moléculaire moyen en nombre de 500 à 10 000 (inclus) ; et le polymère vinylique (A) étant contenu en une quantité de 0,5 partie en masse à 60 parties en masse (inclus) pour 100 parties en masse du polymère acrylique adhésif (B). Si cette composition adhésive est appliquée à un séparateur et ensuite séchée, de manière à obtenir ainsi une couche adhésive, une première Tg qui est la température de transition vitreuse de la couche adhésive entière est de -80 °C à 10 °C (inclus), et une seconde Tg qui est la température de transition vitreuse calculée à partir d’une partie couche de surface de la couche adhésive telle que déterminée par spectroscopie photoélectronique à rayons (X) est de 40 °C ou plus, et est supérieure de 30 °C ou plus à la première Tg.
(JA) 【解決手段】ビニル重合体(A)及びアクリル系粘着性ポリマー(B)を含む粘着剤組成物であって、前記ビニル重合体(A)は、ガラス転移温度(Tg)が60℃以上200℃以下であり、数平均分子量が500以上10,000以下であって、前記アクリル系粘着性ポリマー(B)100質量部に対して0.5質量部以上60質量部以下含有し、前記粘着剤組成物をセパレーターに塗工し、乾燥させて粘着剤層を得た際に、当該粘着剤層全体のガラス転移温度である第1のTgが-80℃以上10℃以下であり、前記粘着剤層のX線光電子分光分析により得られるその表層部分から計算されるガラス転移温度である第2のTgが40℃以上であり、且つ、前記第1のTgよりも30℃以上高い、粘着剤組成物を提供する。
