Title:
POLYESTER RESIN COMPOSITION, PROCESS FOR PRODUCTION THEREOF, AND LAMINATED POLYESTER FILM
Document Type and Number:
WIPO Patent Application WO/2008/029842
Kind Code:
A1
Abstract:
Disclosed is a polyester resin composition which comprises a polyester resin comprising at least an alicyclic dicarboxylic acid component and an alicyclic diol component. The polyester resin composition meets the following requirement: a glass transition temperature of 65 to 90˚C inclusive; a refraction index as measured with sodium D-line of 1.500 to 1.570 inclusive; an element titanium content of 5 to 500 ppm inclusive; an element phosphorus content of 50 to 500 ppm; and a gel fraction of 50% or more. It becomes possible to provide a polyester resin composition which has a low refractive index, a low optical elastic modulus and produces a thermally deteriorated contaminant in a reduced amount.
