    • 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.
    • 本发明涉及一种复合膜,其包括塑料膜和形成在膜的至少一个表面上的保护层,其中保护层由以下混合物制成:(a)具有层状结构的无机可溶胀硅酸盐和 (b)含有重量比(a)至(b)为1:1000和2:1的硅烷醇基的化合物和包含塑料膜和涂层的抗静电复合膜,所述抗静电复合膜形成在至少一个 膜的表面,其中所述涂层由以下混合物制成:(a)具有层状结构且含有至少一种选自具有至多6个碳原子的脂族铵离子中的至少一种离子的可溶胀无机硅酸盐,钠离子,银离子 和锂离子作为层间离子,和(b)选自水溶性化合物和水分散性树脂中的至少一种以(a)至(b)的重量比为1:1000至2:1的组分。 这些复合膜的电气特性,光滑性,光滑性,耐刮擦性,抗静电性等优异,因此适用于各种用途,例如电绝缘材料,包装材料,标签,可写和可擦除材料,印刷层压 薄膜,磁记录介质,微膜等。
