THIOPHOSPHINE COMPOUNDS AND METHOD OF MAKING POLYMERISABLE COMPOSITIONS CONTAINING THEM AND THEIR USE FOR MAKING OPHTALMIC LENSES

摘要

The present invention relates in general to thiophosphine compounds (also named phosphine sulfide compounds) and their use for making polymerizable compositions which after polymerisation give optically transparent articles, such as ophthalmic lenses, having improved mechanical and optical properties and in particular having an improved UV cut.
