CONTAINERS OR FILMS COMPRISING HYDROXYPHENLBENZOTRIAZOLE UV ABSORBERS FOR PROTECTING CONTENTS AGAINST THE EFFECTS OF UV RADIATION

摘要

The contents of clear or lightly colored plastic containers or films are protected from ultraviolet radiation by the incorporation of certain UV absorbers of the class of reactable, durable hydroxyphenylbenzotriazoles in the container or film. The hydroxyphenylbenzotriazoles are reacted into the containers or films via condensation reaction and are thereby covalently bonded therein. Contents to be protected include foodstuffs, beverages, pharma­ceuticals, cosmetics, personal care products, shampoos and the like.
