Abstract:
Thermoplastic composition and articles containing UV absorbers that protect the articles contents from harmful UV radiation are disclosed as well as methods for making the thermoplastic articles and methods for using the articles to contain and protect materials sensitive to UV radiation. The UV absorbers contain oxazolone and/or azine functional groups that absorb UV radiation and prevent its transmission into the article. Many of the compounds are novel compositions of matter. The generally clear thermoplastic articles of this disclosure are particularly useful for containing a variety of UV sensitive consumer products that would otherwise have to be packaged in opaque containers.
