Abstract: An electromagnetic shield includes a plurality of magnetic thin plates stacked on each other, a pair of metal plates sandwiching the plurality of magnetic thin plates, and a plurality of seat plates each connected to the pair of metal plates. The plurality of seat plates are disposed at positions where the total sum of a leakage flux interlinked with a region between mutually adjacent first and second seat plates among the plurality of seat plates is equal to zero. Preferably, a distance between the first and second seat plates is equal to a value which is an integral multiple of a half period of the distribution of the leakage flux.

Abstract: Disclosed is a curable composition including an organic polymer containing a crosslinkable silyl group, an ultraviolet ray absorbing agent having a triazine skeleton and a hindered amine based light stabilizer. The composition exhibits improved weather resistance in a thin layer and thick layer portion. Further, disclosed is a curable composition including an organic polymer containing a crosslinkable silyl group, a (meth)acrylic polymer containing an epoxy group, a divalent tin organic carboxylate and an organic amine compound. The composition exhibits excellent properties. Also, disclosed is a curable composition and sealing material including a reactive organic polymer containing at least one crosslinkable silyl group in one molecule thereof, a reactive organic polymer containing less than one crosslinkable silyl group in one molecule thereof, and thermally expandable hollow spheres. The composition has good physical properties. Also, disclosed is a fire-resistant structure forming method.
