THERMOPLASTIC RESIN SHEET HAVING FUNCTIONALITY IMPARTED BY TRANSFER METHOD AND METHOD FOR PRODUCING SAME

摘要

Disclosed as the first aspect of the present invention is a functional thermoplastic resin sheet comprising a thermoplastic resin sheet having a rough surface and at least one thin film which is formed on the rough surface by a transfer method. Also disclosed is a method for producing such a functional thermoplastic resin sheet wherein the surface temperature of the thermoplastic resin sheet is not less than (Tg - 10°C) and not more than (Tg + 70°C) when Tg is the glass transition temperature of the thermoplastic resin sheet, and a base film having a softening point lower than the surface temperature of the thermoplastic resin sheet is used. Disclosed as the second aspect of the present invention is a light diffusion plate for liquid crystal displays, which has at least one thin film formed on at least one side of a thermoplastic resin sheet by a transfer method. In this light diffusion plate, at least one of the thin films contains an antistatic agent. Further disclosed is a method for producing such a light diffusion plate wherein a thermoplastic resin sheet is extrusion-molded and at least one thin film is transferred on at least one side of the thermoplastic resin sheet in such a manner that at least one of the thin films contains an antistatic agent.
