Title:

THERMOPLASTIC RESIN COMPOSITION, OPTICAL FILM AND ORIENTED FILM

Document Type and Number:

WIPO Patent Application WO/2006/070820

Kind Code:

A1

Abstract:

A thermoplastic resin composition that while retaining low birefringence, exhibits high compatibility and excels in antiweatherability and heat resistance; and an optical film produced therefrom; and a retardation film that excels in antiweatherability and heat resistance and exhibits a reverse wavelength dispersion. The thermoplastic resin composition comprises cycloolefin polymer (B) and vinyl polymer (A) having units of the general formula: (I) wherein each of R¹ to R³ is a hydrogen atom; a halogen atom; a substituted or unsubstituted C₁-C₃₀ hydrocarbon group which may have a linkage group containing an oxygen atom, sulfur atom, nitrogen atom or silicon atom; or a polar group, and n is 0 or a positive integer.
