  • Patent number: 6838168
    Abstract: An anti-fogging thermoplastic resin sheet is provided which has a remarkably improved strength in an anti-fogging coating film thereof, inhibiting coating film breakage during the forming, and which exerts excellent anti-fogging effects even in the case of a deep drawn formed articles and can prevent transfer of the anti-fogging coating film to the opposite surface when the anti-fogging thermoplastic resin sheet is wound in a roll. A formed article having excellent anti-fogging effects is also provided. A thermoplastic resin sheet comprising polystyrene, a polymer alloy of polystyrene and a rubber, a high-impact styrene resin, a copolymer of styrene and an acrylic monomer, polyolefin, polyethylene terephthalate, polyvinyl chloride or polyvinylidene chloride comprises on the surface thereof an anti-fogging coating film comprising a surfactant (A) and cyclodextrin or a water-soluble compound (B) in which hydroxyl groups of cyclodextrin are modified.

  • Publication number: 20020045027
    Abstract: An anti-fog resin sheet provides anti-fog effects in a molded article, especially anti-fog effects in the molded article under low-temperature conditions, which are remarkably enhanced, and an anti-fog agent used in the same, and a molded article having excellent anti-fog effects. The anti-fog resin sheet comprises a resin sheet and an anti-fog coating film formed on the surface of the resin sheet, wherein the anti-fog coating film is composed of a nonionic surfactant (A) and a metal carboxylate salt compound (B) and the metal carboxylate salt compound (B) has a hydrate forming ability and is in an amorphous state. The anti-fog agent comprising a nonionic surfactant (A), a metal carboxylate salt compound (C) having a hydrate forming ability, and a metal ion (D) of a metal atom having a first ionization energy which is higher than that of a metal ion in the metal carboxylate salt compound (C). The molded article is produced by molding the anti-fog resin sheet.
