  • Patent number: 5814684
    Abstract: The present invention provides an anti-fogging agent for the surface of a thermoplastic resin sheet which exerts the following excellent effects:(1) The effect of inhibiting fogging on the surface of the sheet due to the condensation of vapor can last over an extended period of time;(2) Excellent blocking resistance and coating stability make the anti-fogging surface less peelable in the procedure of heating it over a heating plate in a direct heating process so that it is formed into various shapes; and(3) The incorporation of a polyvalent alcohol having wetting properties in a predetermined amount provides excellent antistatic properties. The present invention provides an anti-fogging thermoplastic resin sheet treated with the foregoing anti-fogging agent.
