摘要:
An electric wave shielding material provided to be adhered to a window. The material includes a body member composed of a light transmitting surface material; a light transmitting electrically conductive layer provided on the light transmitting surface material; and a light transmitting adhesive provided on at least a part of the light transmitting electrically conductive layer in such a manner that a part of the light transmitting electrically conductive layer is exposed to form a connecting electrically conductive portion. A connecting piece composed of a member for converting an electric wave into a heat energy is connected to the connecting electrically conductive portion, and includes an adhesive layer.

A hard coat film is providend, having excellent resistance to impact and weather, and high surface hardness, which is suitable for being stuck on the external surfaces, e.g., those of window panes or plastic boards for windows. In the hard coat film, a silicon-base hard coat layer is provided on one side of a multi-layered base composed of a plurality of the same or different laminated resin films.

A release sheet is provided. The release sheet comprises: a base material having one surface and the other surface; and a release agent layer provided on the one surface of the base material. The release agent layer contains substantially no silicone compound and is constituted of a polymer material containing a polyolefine-based thermoplastic elastomer of which density is in the range of 0.80 to 0.90 g/cm3. A Young's modulus of the release agent layer is in the range of 0.1 to 0.3 GPa. An arithmetic mean deviation of a profile Ra of the other surface of the base material is in the range of 100 to 1800 nm. This makes it possible to sufficiently suppress adverse effects on electric components and the like, prevent blocking from occurring when the release film is wound up in a rolled form and stored in this state, and exhibit superior releasability. A pressure-sensitive adhesive article is also provided.

An electrostatic charge on a release sheet is prevented, and thus workability during paying out of a release sheet from a roll is improved.A release sheet 10 comprises a release sheet base 11, an undercoat layer 12 formed on the release sheet base 11, and a release agent layer 13 formed on the undercoat layer 12. The undercoat layer 12 contains a polyolefin-type antistatic agent with specific surface resistance (ASTM D 257) of less than or equal to 109Ω. The surface resistivity (JIS K 6911) of the release sheet 10 is less than or equal to 1014 Ω/square.

摘要:
A film having an antistatic releasing agent layer comprising fiber-shaped carbon and disposed on at least one of the faces of a substrate film, a release film having a releasing agent layer disposed on one face of a substrate and an antistatic layer which comprises a cured product of a resin composition of the active energy ray curing type comprising fiber-shaped carbon or a combination of fiber-shaped carbon and an electrically conductive macromolecular compound and is disposed on the other face of the substrate film, and processes for producing the films. The release films have a relatively small thickness of the antistatic layer, exhibit the stable antistatic function, are excellent in smoothness, do not adversely affect hardening of the resin releasing agent, exhibit the excellent releasing function and provide the excellent productivity.
摘要:
A membrane for the separation of an organic solvent from a water-organic solvent mixture has a polymeric membrane of a copolymer consisting essentially of an .alpha., .beta.-unsaturated carbonyl compound as a main monomer. The .alpha., .beta.-unsaturated carbonyl compound includes an acrylic acid ester or a methacrylic acid ester. The polymeric membrane has a crosslinked structure. The polymeric membrane is carried on a support member in the form of a flat membrane, a pipe or a hollow fiber. The polymeric member includes particles therein. The polymeric membrane is sandwiched by the support members to form a composite-type separation membrane. The composite-type separation membrane is modulated.
