Anti-fog resin sheet, anti-fog agent and molded article

摘要

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.
