Novel substituted naphthopyrans |
摘要 |
Described are novel reversible photochromic 2H-naphtho[1,2-b]pyran compounds. Certain substituents are present at the 2 and 5 positions and sometimes at the 6 position of the naphthopyran ring. Also described are organic host materials that contain or that are coated with such compounds. Articles such as ophthalmic lenses or other plastic transparencies that incorporate the novel naphthopyran compounds or combinations thereof with complementary photochromic compounds, e.g., spiro(indoline) type compounds, are also described. |
