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 .OMEGA./.square. and a surface roughness (Ra) of 5 to 50 nm; and an antistatic paint for use therein.

L'invention concerne un article moulé antistatique obtenu uniquement par revêtement d'un substrat avec une peinture antistatique. La surface de l'article moulé antistatique est lisse, ne détériore pas la transparence et la coloration du substrat, et présente d'excellentes propriétés antistatiques.
