20130310556 | PHOTOCHROMIC FUSED NAPHTHOPYRANS HAVING A BENZENE RING WHICH IS ADJACENT TO THE PYRAN OXYGEN AND IS LINKED TO THE PARA SUBSTITUENT VIA BOTH META POSITIONS - The present invention relates to photochromic fused naphthopyrans having a benzene ring which is adjacent to the pyran oxygen and is linked to the para substituent via both meta positions, and to the use thereof in plastics of all types, in particular for ophthalmic purposes. | 11-21-2013 |
20140235876 | Photochromic Double-Fused Naphthopyrans - The present invention relates to photochromic double-fused naphthopyrans of the general formula (I) or (II) and the use thereof in plastics of all kinds, particularly for ophthalmic purposes. The photochromic compounds according to the invention are characterized by two distinct absorption bands of the open form in the visible wavelength range, i.e. two conventional photochromic dyes, each having only one discrete absorption band, can be replaced with dye molecules of this type. The compounds according to the invention, moreover, have a very good lifetime with a very high performance. | 08-21-2014 |
20140330028 | Photochromic Bis-Idenofused Naphthopryans - The present invention relates to photochromic double-indeno-fused naphthopyrans of the general formula (I) and the use thereof in plastics of all kinds, particularly for ophthalmic purposes. The photochromic compounds according to the invention are characterized by two distinct absorption bands of the open form in the visible wavelength range, i.e. two conventional photochromic dyes, each having only one discrete absorption band, can be replaced with dye molecules of this type. The compounds according to the invention, moreover, have a very good lifetime with a very high performance. | 11-06-2014 |
20150152246 | PHOTOCHROMIC FLUORENOPYRANS WITH DEFINED DIBENZO[B,D]PYRANO FUSED ATTACHMENT - The present invention relates to photochromic fluorenopyrans with defined dibenzo[b,d]pyrano fusion in accordance with general formulae (I) or (II) and to their use in plastics of all kinds, particularly for ophthalmic purposes. The photochromic compounds of the invention are distinguished by two pronounced absorption bands of the open form in the visible wavelength range, meaning that with dye molecules of this kind it is possible to replace two conventional photochromic dyes each having only one discrete absorption band. The compounds of the invention, moreover, have a very good lifetime with very high performance. | 06-04-2015 |
