Abstract: This gas barrier laminate comprises a base layer; a gas barrier layer laminated on one surface (A) of the base layer, directly or with another layer sandwiched therebetween; a protective film (?) laminated directly on the gas barrier layer; and a protective film (?) laminated on a surface (B) opposite to the surface (A) of the base layer, directly or with another layer sandwiched therebetween, wherein the gas barrier layer contains a specific inorganic compound, and an adhesion at the time of peeling the protective film (?) and an adhesion at the time of peeling the protective film (?) under specific conditions are both less than or equal to specific values.

Abstract: The present invention is: a curable composition for forming a primer layer of a gas barrier laminated film, comprising at least a polar group-containing polyolefin polymer and a polyfunctional acrylate compound; a gas barrier laminated film having a primer layer made of a cured product of the curable composition; and a gas barrier laminate including an organic compound-containing layer laminated on the surface of the gas barrier laminated film. The present invention provides: a curable composition that is for forming a primer layer suitably used in manufacturing a gas barrier laminate excellent in interlayer adhesion, a gas barrier laminated film having a primer layer made of the cured product of the curable composition, and a gas barrier laminate comprising an organic compound-containing layer laminated on the surface of the gas barrier laminated film.

Abstract: The invention is a laminate comprising at least a base layer, a gas barrier layer, and a layer composed of a cured product of an energy-curable resin, wherein: the gas barrier layer is laminated directly or via another layer on one side of the base layer; and the layer composed of the cured product of the energy-curable resin is laminated directly or via another layer on a side opposite to the gas barrier layer of the base layer. According to the present invention, there are provided a laminate excellent in gas barrier properties and unlike to cause a curl and a thermal contraction even when a thermal history is given so as to be suitably applicable to a sticking process to electronic devices, a member for electronic devices composed of the laminate, and an electronic device equipped with the member for electronic devices.

Abstract: The present invention relates to: a gas-barrier laminated sheet having a layer structure of release sheet (A)/gas-barrier layer/adhesive resin layer/release sheet (B), wherein arithmetic average roughness (Ra) of a surface on the release sheet (A) side of the gas-barrier layer is 5 nm or less, and maximum cross-section height (Rt) of the surface is 100 nm or less; a process for producing the gas-barrier laminated sheet; and an electronic member or an optical member, including a gas-barrier layer and an adhesive resin layer derived from the gas-barrier laminated sheet. The present invention provides: a gas-barrier laminated sheet excellent in sealing performance and bending properties and a process for producing the same, and an electronic member and an optical member including a gas-barrier layer and an adhesive resin layer derived from the gas-barrier laminated sheet.

Abstract: An acid pickling tank 11 is filled with an acid liquid L, and a lid 12 is attached to the acid pickling tank 11. A central part of the lid 12 is depressed downwards to form a covering portion 12b. The covering portion 12b is located at a lower position than the liquid level of the acid liquid L in the acid pickling tank 11 to cover a free surface of the acid liquid L. Immersion guide rolls 20a to 20e are provided on the covering portion 12b, support blocks 21a to 21e are provided at the bottom of the acid pickling tank 11, and skids 23a to 23e are provided on the support blocks 21a to 21e via a bottom plate 22. Thus, the free surface of the acid liquid L in the acid pickling tank 11 is decreased to suppress a loss of the acid, and prevent an overflow of the acid liquid L to the outside of the tank, thereby making acid pickling of the strip steel plate S efficient.

Abstract: An acid pickling tank body 11 is partitioned with a partition wall 12 into a first tank 13 and a second tank 14. The first tank 13 and the second tank 14 are filled with acid liquids L1 and L2, respectively, of different concentrations. A lid 15 is attached to the top of the acid pickling tank body 11. On the lid 15, immersion guide rolls 25a to 25d, 26a to 26d are mounted. On the bottom surface of the first tank 13 and the second tank 14, skids 31a to 31e, 32a to 32d are mounted via support blocks 27a to 27e, 28a to 28d. A liquid seal 22 is provided which has a cushion nozzle 38 for jetting the acid liquids L1 and L2 toward the surface of a strip steel plate S. traveling above the partition wall 12 for the first tank 13 and the second tank 14.
