ABSTRACT:
Photodegradation and light-stabilizing amounts of a combination of an oxalanilide UV absorber and a hindered amine light stabilizer are applied to a dyed polyester fabric providing a lightfastness rating of at least 4 AATCC Gray Scale following 100 hours WeatherOmeter exposure. Fabrics so protected are useful for automotive fabrics and draperies.
