Title:
THERMOPLASTIC RESIN SHEET HAVING FUNCTIONALITY IMPARTED BY TRANSFER METHOD AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2007/052579
Kind Code:
A1
Abstract:
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.
