  • Patent number: 9263677
    Abstract: A method for manufacturing a transparent gas barrier film for an organic electroluminescence element having a substrate with a gas barrier layer thereon. The gas barrier layer is formed on the substrate by plasma CVD using an organic silicon compound as a raw material gas and an oxygen gas as a decomposition gas. Formation of the gas barrier layer is carried out so that a carbon content of the gas barrier layer in the thickness direction repeatedly changes more than two times from high value, via intermediate value, low value and intermediate value, to high value.

  • Patent number: 9127186
    Abstract: A film sealant useful for tightly sealing an electric device at a low temperature and a sealing method of using the sealant are provided. The device is covered and sealed by covering at least a region of the device with a film sealant containing a copolyamide-series resin, heat-melting the sealant, and cooling the sealant. The copolyamide-series resin may have a melting point or softening point of 75 to 160° C. and may be a crystalline resin. The copolyamide-series resin may be a multiple copolymer or may contain a unit derived from a long-chain component having a C8-16alkylene group (e.g., a C9-17lactam and an aminoC9-17alkanecarboxylic acid). The film sealant may cover one side of the device.
