<p><P>PROBLEM TO BE SOLVED: To provide a gas barrier sheet having a high water vapor gas barrier property. <P>SOLUTION: The gas barrier sheet has a gas barrier layer. The gas barrier layer contains a nanosheet (a), an organic onium compound (b), and an acryl resin (c). The nanosheet (a) is a cleaved object of one or more of lamellar inorganic compounds selected from the group consisting of a smectite group and a mica group. The nanosheet (a) has the average aspect ratio of 150 or more. The acrylic resin (c) has at least one type or more of an amino group, an amide group, and an isocyanuric acid ring. In the gas barrier layer, the nanosheet (a) is laminated so that the surface direction of the nanosheet (a) is approximately parallel to the surface direction of the gas barrier layer. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
