Beschreibung
Zusammenfassung:	A curable composition comprises (a) a mercapto-functional siloxane; (b) a siloxane comprising unsaturated functional groups; (c) a photoinitiator; and (d) an antioxidant compound. In one embodiment, the antioxidant is chosen from a hindered phenolic compound. The curable compositions can be utilized to form a cured article, which may be useful in a variety of applications including, but not limited to, optical applications. The cured articles from the cured compositions may exhibit good physical properties including, for example, high refractive index. The articles may also exhibit good thermal stability.
