Abstract: Disclosed is a structure which can maintain a capability of conducting or absorbing electromagnetic waves even when an external pressure is applied thereon. The structure (1) includes a fibrous protrusion (1b) having the capability of conducting or absorbing electromagnetic waves partially arranged on a substrate (1a) so that at least a part of a fiber of the fibrous protrusion is positioned outward from a surface of the substrate (1a). The structure further includes a fiber protector (1c) arranged at least partially of a portion in a surface (1a1) of the substrate (1a) where no fibrous protrusion (1b) is arranged, in which the fiber protector is capable of suppressing or preventing the fibrous protrusion (1b) from flattening.

Abstract: The present invention relates to an article to which a characteristic of shielding electromagnetic waves is imparted, which comprises at least a sheet-like electromagnetic shielding structure, the sheet-like electromagnetic shielding structure comprising a thin layer-like substrate; and a fiber convex structure section having a characteristic of conducting or absorbing electromagnetic waves, in which the said fiber convex structure section is formed at least partially on the thin layer-like substrate in such a form that at least a part of a fiber thereof is positioned outward from the surface of the thin layer-like substrate. As the article including the sheet-like electromagnetic shielding structure, an electronic device, an electronic circuit board, garment, an architectural structure, a construction material, or a transport equipped with an engine is suitable.

Abstract: A protective tape used for optical member comprising a plastic film base, a pressure-sensitive adhesive layer formed on one side of the plastic film base and a treated layer formed on an opposite side of the plastic film base, wherein the treated layer has a structure in which a copolymer (A) including (a) an alkyl (meth)acrylate having an alkyl group with carbon numbers of 8 to 20; (b) (meth)acrylonitrile; and (c) a monomer having functional groups copolymerizable with the component (a) and the component (b), as copolymerization components, is cross-linked by a cross-linking agent. The protective tape used for optical member is enabled to direct print with an ink on the treated layer and have a low adhesive property with the pressure-sensitive adhesive applied to an optical film and have a solvent resistance.

Abstract: A structure having a characteristic of conducting or absorbing electromagnetic waves contains a base material having a characteristic of conducting or absorbing electromagnetic waves, a pressure-sensitive adhesive layer or an adhesive layer formed on at least one surface thereof, and a fiber convex structure section having a characteristic of conducting or absorbing electromagnetic waves formed on the pressure-sensitive adhesive layer or adhesive layer on the at least one surface of the base material in a form that at least a part of a fiber thereof is positioned outward from the surface of the pressure-sensitive adhesive layer or adhesive layer.

Abstract: A protective tape used for optical member includes a plastic film base, an adhesive layer formed on one side of the plastic film base, and a treated layer formed on an opposite side of the plastic film base. The treated layer is formed with a treat agent containing a silicone resin and a cellulose polymer. The protective tape used for optical member is enabled to direct print with an ink on the treated layer and have a low adhesive property with the adhesive applied to an optical film.

Abstract: A protective tape used for optical member comprising a plastic film base, an adhesive layer formed on one side of the plastic film base and a treated layer formed on an opposite side of the plastic film base, wherein the treated layer is formed with a treat agent comprising a release agent containing long chain alkyl group or silicone resin, and a cellulose polymer. The protective tape used for optical member is enabled to direct print with an ink on the treated layer and have a low adhesive property with the adhesive applied to an optical film.
