Patent

CA 2343310

Described are novel photochromic polymerizable polyalkoxylated naphthopyran compounds, examples of which are certain 2H-naphtho[1,2-b]pyrans, 3H-naphtho[2,1-b]pyrans and indeno[2,1-f]naphtho[1,2- b]pyrans each having at least one polyalkoxylated substituent of from 1 to 50 alkoxy units per substituent which is end-capped with a polymerizable group. Specific substituents are also present on the naphtho, indeno and pyrano portions of the compounds. These compounds may be represented by graphic formulae (I), (II) or (III). Also described are various substrates, e.g., paper, glass, polymeric organic materials, etc., that contain or that are coated with such compounds. Optically clear articles such as contact lenses or other plastic transparencies that incorporate the novel naphthopyran compounds or combinations thereof with complementary photochromic compounds, e.g., certain other naphthopyrans, indenonaphthopyrans, benzopyrans, oxazine-type compounds, etc., are also described.

L'invention concerne de nouveaux composés de naphtopyrane polyalcoxylé polymérisable photochromique, par exemple certains 2H-naphto[1,2-b]pyranes, 3H-naphto[2,1-b]pyranes et indéno[2,1-f]naphto[1,2-b]pyranes, chacun de ceux-ci comportant au moins un substituant polyalcoxylé composé de 1 à 50 unités d'alcoxy par substituant, et qui est coiffé à une extrémité par un groupe polymérisable. Des substituants spécifiques sont également présents sur les parties naphto, indéno, et pyrano des composés. Les composés peuvent être représentés par les formules graphiques (I), (II) ou (III). L'invention concerne également divers substrats tels que papier, verre, matières organiques polymères etc., qui contiennent ou sont revêtus de ces composés. L'invention concerne également des articles optiques transparents tels que des lentilles de contact ou d'autres articles transparents en plastique qui incorporent les nouveaux composés de naphtopyrane ou des combinaisons de ceux-ci avec des composés photochromiques complémentaires, p. ex. certains autres naphtopyranes, indénonaphtopyranes, benzopyranes, composés du type oxazine, etc.
