摘要： The present invention relates to a composite film comprising a plastic film and a protective layer which is formed on at least one surface of the film, wherein the protective layer is made of a mixture comprising (a) an inorganic swellable silicate having a layered structure and (b) a compound containing a silanol group at a weight ratio of (a) to (b) of between 1:1000 and 2:1 and an antistatic composite film comprising a plastic film and a coating layer which is formed on at least one surface of the film, wherein said coating layer is made of a mixture comprising (a) a swellable inorganic silicate having a layered structure and containing at least one ion selected from among aliphatic ammonium ions having at most 6 carbon atoms, sodium ion, silver ion and lithium ion as an interlayer ion and (b) at least one member selected from among water-soluble compounds and water-dispersible resins at a weight ratio of (a) to (b) of between 1:1000 and 2:1. These composite films are excellent in electrical characteristics, smoothness, slipperiness, anti-scratching properties, antistatic properties and the like, so that they are suitable for various uses such as electrical insulating material, wrapping material, labels, writable and erasable materials, print lamination film, magnetic recording medium, micro-film or the like.
