Title
(EN) PHOTOCHROMIC SPIROPYRAN COMPOUNDS
(FR) COMPOSES SPIROPYRANIQUES PHOTOCHROMIQUES
Abstract
(EN)
Described are a series of novel benzospiropyran and naphthospiropyran compounds in which a norcamphor group (or its alkyl-substituted homologues) or a tricyclodecane group (or its alkyl-substituted derivatives) are appended at the 2-positiion of the benzospiropyran or naphthospiropyran ring. Also described are organic host materials that contain or that are coated with materials containing such compounds. Articles, such as ophthalmic or plano lenses, that incorporate the novel pyran compounds or combinations of the novel pyran compounds with other complementary photochromic compounds are described.
(FR)
Est décrite une série de nouveaux composés benzospiropyraniques et naphtospiropyraniques dans lesquels un groupe norcamphre (ou se homologues à substitution alkyle) ou un groupe tricyclodécane (ou ses dérivés à substitution alkyle) sont joints à la position 2 du composé cyclique benzospiropyranique ou naphtospiropyranique. Sont décrites également des matières organiques hôtes qui contiennent ou qui sont revêtues de matières renfermant de tels composés. Des articles, tels que les lentilles ophtalmiques ou planolentilles, qui englobent les nouveaux composés pyraniques ou des combinaisons des nouveaux composés pyraniques avec d'autres composés photochromiques complémentaires, sont décrits.
