SILICONE MATERIAL HAVING A PHOTOCHROMIC ADDITIVE

摘要

A silicone-based material that incorporates a photochromic molecule, and methods of making the same. The material changes color when exposed to ultraviolet radiation, thereby providing a convenient indicator of exposure. The material reverts to its original color after the source of ultraviolet radiation is removed. Compositions and articles that comprise a silicone-based material that incorporates a photochromic dye.
