RESIN COMPOSITION

PROBLEM TO BE SOLVED: To provide a resin composition which has good transparency, moisture permeation resistance, heat resistance, moist heat resistance, and antistatic properties, and to provide a resin composition sheet obtained from the same which enables varnish coating, can be simply formed into a sheet, does not require a heating and curing step, can greatly reduce thermal degradation of an organic EL element but also can greatly enhance productivity.SOLUTION: There is provided a resin composition which contains a polyisobutylene resin, a modified polyolefin resin, a tackifier resin, a polystyrene-polyolefin block copolymer, and an ionic surfactant, and to provide a resin composition sheet in which a resin composition layer formed from the resin composition is formed on the support.SELECTED DRAWING: None 【課題】良好な透明性、耐透湿性、耐熱性、耐湿熱性、帯電防止性を併せ持った樹脂組成物、及びそれから得られる、ワニス塗工が可能で、簡便にシート化することができ、加熱硬化工程を必要とせず、有機ＥＬ素子の熱劣化を大幅に低減できるだけでなく、生産性を大幅に向上させることができる樹脂組成物シートを提供する。【解決手段】ポリイソブチレン樹脂、変性ポリオレフィン樹脂、粘着付与樹脂、ポリスチレン−ポリオレフィンブロック共重合体及びイオン性界面活性剤を含有する樹脂組成物及び支持体上に該樹脂組成物による樹脂組成物層を形成した樹脂組成物シート。【選択図】なし
