[PYRROLE] NAPHTOPYRANES, THEIR PREPARATION, THE POLYMERIC COMPOSTIONS AND (CO) MATRICES CONTAINING THEM |
| abstract |
The present invention relates to new compounds of naphthopyran type having a pyrrole group ringed in position 5, 6 as well as the photochromic compositions and in particular the (co) polymer matrices containing them. Said compounds exhibit interesting photochromic properties. The general formula of these [pyrrole] naphthopyran compounds is as follows: (CF DRAWING IN BOPI) The invention also relates to ophthalmic articles comprising these photochromic compositions: ophthalmic and / or sunglasses, lenses, glazing, etc. |
