    摘要： The present invention relates to photochromic materials that include certain indeno-fused naphthopyrans. The indeno-fused naphthopyrans have an amino group (e.g., a piperidino or morpholino group) bonded to the 6-position and hydrogen or a halo group (e.g., fluoro) bonded to the 11-position thereof. The photochromic materials of the present invention can have a closed-form electromagnetic radiation absorption spectrum that is shifted to longer wavelengths (e.g., wavelengths of greater than 390 nm), relative to comparable photochromic materials. The present invention also relates to optical elements, such as eyeglasses, that include the photochromic materials of the present invention.

    摘要： Described are novel reversible photochromic 2H-naphtho[1,2-b]pyran compounds, examples of which are compounds having certain substituents at the 5 and 6-positions of the naphtho portion of the naphthopyran and at the 2-position of the pyran ring, e.g., 2,2-bis(4-methoxy phenyl)-5-methoxycarbonyl-6-morpholino-2H-naphtho[1,2-b]pyran. Certain substituents may also be present at the number 7, 8, 9 or 10 carbon atoms of the naphtho portion of the naphthopyran. Also described are organic host materials that contain or that are coated with such compounds. Articles such as ophthalmic lenses or other plastic transparencies that incorporate the novel naphthopyran compounds or combinations thereof with complementary photochromic compounds, e.g., spiro(indoline) type compounds, are also described.
