LIQUID CASTING COMPOSITIONS, PRODUCTION PROCESSES AND PHOTOCHROMIC OPTICAL ELEMENTS |
摘要 |
The present invention provides a liquid casting composition for producing photochromic optical elements, the composition including: (i) an acrylate or methacrylate monomer; (ii) a photochromic compound; (iii) a terpinolene-based radical chain transfer agent; and (iv) a thermal free radical initiator. Also provided are methods for producing photochromic optical elements using the liquid casting composition and photochromic optical elements produced thereby. The photochromic optical elements include, for example, ophthalmic lenses. |
