Beschreibung
Zusammenfassung:	Described herein are tri-functional compounds useful in the production of ophthalmic lenses. The compounds are composed of UV absorber having a polymerization initiator directly or indirectly bonded to the ultraviolet absorber, and an olefinic group directly or indirectly bonded to the ultraviolet absorber. Also described herein are polymers and ophthalmic lenses produced from the tri-functional compounds described herein. Cette invention concerne des composés trifonctionnels utilisés dans la production de lentilles ophtalmiques. Ces composés contiennent un absorbeur dultraviolets comportant un initiateur de polymérisation directement ou indirectement lié à labsorbeur dultraviolets, et un groupe oléfinique directement ou indirectement lié à labsorbeur dultraviolets. Linvention concerne également les polymères et les lentilles ophtalmiques produits à partir des composés trifonctionnels décrits ici.
