阻气膜及其制造方法、阻气膜层叠体、电子装置用构件、以及电子装置
摘要：
本发明为阻气膜及其制造方法、将2片以上所述阻气膜层叠而成的阻气膜层叠体、包含所述阻气膜或阻气膜层叠体的电子装置用构件、和具备该电子装置用构件的电子装置，所述阻气膜为具有固化树脂层与该固化树脂层的至少单面上的阻气层的阻气膜，其中，所述固化树脂层是包含含有玻璃化转变温度（Tg）为140℃以上的热塑性树脂（A）、和固化性单体（B）的固化性树脂组合物的固化物的层，阻气膜的水蒸汽透过率在40℃、相对湿度90%气氛下为1g/m2/day以下。本发明的阻气膜和阻气膜层叠体的耐热性、耐溶剂性、层间密合性、和阻气性优异，并且双折射率低、光学各向同性优异，因而可适宜地用作电子装置用构件。
摘要（英）：

The present invention provides: a gas barrier film comprising a cured resin layer and a gas barrier layer, the gas barrier layer being provided on at least one side of the cured resin layer, the curedresin layer being a layer formed of a cured product of a curable resin composition that includes (A) a thermoplastic resin having a glass transition temperature (Tg) of 140 DEG C. or more, and (B) acurable monomer, the gas barrier film having a water vapor transmission rate of 1 g/m<2>/day or less at a temperature of 40 DEG C. and a relative humidity of 90%; a method for producing the gas barrier film; a gas barrier film laminate formed by laminating more than two gas barrier films; an electronic device member comprising the gas barrier film or the gas barrier film laminate; an electronic device comprising the electronic device member. Since the gas barrier film and the gas barrier film laminate of the present invention exhibits excellent heat resistance, excellent solvent resistance, excellent interlayer adhesion, and an excellent gas barrier capability, has a low birefringence, and exhibits excellent optical isotropy, the gas barrier film and the gas barrier film laminate may suitably be used as an electronic device member.
