titleOfInvention Hydroxylated / carboxylated naphthopyran
abstract Described are novel photochromic hydroxylated/carboxylated 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 hydroxylated/carboxylated substituent. Specific substituents are also present on the naphtho, indeno and/or pyrano portions of the compounds. These compounds may be represented by the graphic formulae (I), (II) and (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.
