    Abstract: An antistatic molded article obtained only by coating a substrate with an antistatic paint, which antistatic molded article has smooth surface, does not deteriorate the transparency and coloration of substrate and excels in antistatic properties. In particular, an antistatic molded article comprising a substrate of complex configuration such as three-dimensional configuration having irregularity and, superimposed thereon, an antistatic layer. There is also provided an antistatic paint whose application is easy, which antistatic paint does not need any after treatment and excels in transparency, surface smoothness and antistatic properties. More specifically, there are provided an antistatic molded article comprising a substrate and, superimposed on a surface thereof, an antistatic layer from an antistatic paint containing a conductive metal oxide, which antistatic molded article exhibits a surface resistivity of 1×104 to 1×109 Ω/□ and a surface roughness (Ra) of 5 to 50 nm; and an antistatic paint for use therein.

    Abstract: An anionic surfactant having a thermal weight loss initiation temperature of at least 250° C. is incorporated with a thermoplastic resin comprising a graft copolymer formed by graft-polymerizing an ethylenically unsaturated monomer onto a rubber trunk polymer obtained by emulsion polymerization using a carboxylic acid-type surfactant. As a result, it is possible to obtain an antistatic resin composition which can be effectively produced on an industrial scale and can provide a shaped product excellent in permanent antistatic property and free from haze or discoloration even when processed under severe processing conditions.

    Abstract: Disclosed is a thermoplastic flexible film suitable for wrapping static sensitive devices such as electronic circuit boards. The film is made of an inherently hydrophilic polyether block amide copolymer in blend with a compatible polymer. Compatible polymers typically are amide polymers or are acid copolymers, such as the nylons or ionomers. The film does not have a degree of hydrophilicity unsuitable for packaging static sensitive devices. Yet the film is antistatic without requiring the addition of an antistatic agent.
