    Abstract: A polyester resin composition for light reflector base, causing only a small amount of outgas in the process of molding a light reflector base or producing a light reflector, excellent in adhesiveness with a metal film layer provided to the surface of the light reflector base, and capable of keeping high luminance even when exposed under high-temperature atmospheres will be provided. The polyester resin composition for light reflector base of the present invention, on the surface of which a light reflecting layer is provided, contains (A) 100 parts by weight of polyester resin, and (B) 0.05 to 2 parts by weight of modified polyolefin resin having a weight-average molecular weight of 2,000 or larger, and an acid value of larger than 1 mg KOH/g and smaller than 10 mg KOH/g.

    Abstract: Polyester compositions are disclosed that include polyester polymers or copolymers having incorporated therein metallic molybdenum particles that improve the reheat properties of the compositions. Processes for making such compositions are also disclosed. The molybdenum particles may be incorporated in the polyester by melt compounding, or may be added at any stage of the polymerization, such as during the melt-phase of the polymerization. A range of particle sizes may be used, as well as a range of particle size distributions. The polyester compositions are suitable for use in packaging made from processes in which a reheat step is desirable.
