Abstract

L'invention a trait à de nouveaux composés photochromiques réversibles de 2H-naphtho [1,2-b] pyran. Parmi ces composés, certains comportent certains substituants au niveau de l'atome de carbone 5 de la partie naphtho du naphtopyran et à la position 2 du noyau pyran. Certain substituants peuvent également se trouver au niveau des atomes de carbone 6, 7, 8, 9 ou 10 de la partie naphtho du naphtopyran. L'invention concerne également des matériaux organiques hôtes contenant ces composés ou revêtus de ceux-ci. Elle porte également des articles tels que des lentilles ophtalmiques ou des diapositives en plastique renfermant ces nouveaux composés de naphtopyran ou leurs combinaisons avec des composés photochromiques complémentaires, notamment des composés du type spiro(indoline).
