Patent

CA 2256478

Described are novel photochromic indeno-fused naphthopyran compounds, examples of which are naphthopyran compounds having a substituted or unsubstituted indeno group, the 2,1 positions of which are fused to the f side of the naphtho portion of the naphthopyran, and having certain substituents at the 3- position of the pyran ring. Certain substituents may also be present at the number 5, 6, 7, 8, 9, 10, 11, 12 or 13 carbon atoms of the compounds. These compounds may be represented by graphic formula (I). Also described are polymeric organic host materials that contain or that are coated with such compounds. Optically clear articles such as ophthalmic lenses or other plastic transparencies that incorporate the novel naphthopyran compounds or combinations thereof with complementary photochromic compounds, e.g., certain other naphthopyrans, benzopyrans and spiro(indoline)type compounds, are also described.

L'invention concerne de nouveaux composés naphtopyrane indénofusionnés, dont des exemples sont des composés naphtopyranes possédant un groupe indéno substitué ou non substitué, dont les positions 2, 1 sont fusionnées au côté f de la partie naphto du naphtopyrane, et possédant certains substituants au niveau de la position 3 du noyau pyrane. Certains substituants peuvent également être présents au niveau des atomes de carbone numéros 5, 6, 7, 8, 9, 10, 11, 12 ou 13 des composés. Ces composés peuvent être représentés par la formule graphique (I). L'invention concerne également des matériaux récepteurs organiques polymères contenant ces composés ou enrobés de ces composés. Elle concerne, de plus, des articles optiques transparents, tels que des lentilles ophtalmiques ou d'autres articles en plastique transparent incorporant ces nouveaux composés naphtopyranes ou leurs combinaisons avec des composés photochromiques complémentaires, par exemple certains autres naphtopyranes, benzopyranes ou des composés de type spiro(indoline).
