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 cured resin 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°C or more, and (B) a curable monomer,
the gas barrier film having a water vapor transmission rate of 1 g/m2/day or less at a temperature of 40°C and a relative humidity of 90%; a method for producing the gas barrier film; a gas barrier film laminate comprising the gas barrier film; an electronic device member comprising the gas barrier film; an electronic device member comprising 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.
本发明提供:一种气体阻隔薄膜,包括固化
树脂层和气体阻隔层,气体阻隔层至少设置在固化
树脂层的一侧、
固化
