The present invention is a composition containing a polyester resin containing at least an alicyclic dicarboxylic acid component and an alicyclic diol component, and it is a polyester resin composition which satisfies that a glass transition temperature is 65&#xb0; C. or more and 90&#xb0; C. or less, a refractive index at sodium D line is 1.500 or more and 1.570 or less, a titanium element content is 5 ppm or more and 500 ppm or less, a phosphorus element content is 50 ppm or more and 500 ppm or less and a gel fraction is 50% or less. By the present invention, it is possible to obtain a polyester resin composition having a low refractive index and photoelastic coefficient, and in which a thermally degraded foreign substance is reduced.

Polyester resin composition, production method thereof and laminate polyester film

The present invention provides a polyester composition for a solar battery, which includes a dicarboxylic acid component having terephthalic acid as a main component and a diol component having ethylene glycol as a main component, the polyester composition satisfying the following Formulae (1) to (5): 0.65&#x2266;intrinsic viscosity&#x2266;0.90 (1); 0.7&#x2266;M/P&#x2266;1.3 (2); 200 ppm&#x2266;P&#x2266;600 ppm (3); amount of terminal carboxyl groups&#x2266;15 eq/t (4); and amount of terminal methoxy groups&#x2266;10 eq/t (5) (in the Formula (2), M represents the number of moles of an alkaline metal element and/or an alkaline earth metal element per 10g of a polyester; and P represents the number of elemental phosphorus per 10g of a polyester).
