Beschreibung
Zusammenfassung:	The invention provides UV-barrier formulations which result in products which effectively resist the transmission of ultraviolet light therethrough. The invention also provides UV-barrier formulations which result in products with improved resistance to ultraviolet light. In particular, the invention provides UV barrier formulations for polyester resins that have improved resistance to ultraviolet radiation, and significantly reduce ultraviolet light transmission in the resulting resin products. The invention also provides products and manufacturing processes based on the above formulations.
