| titleOfInvention | Novel water soluble photochromic compounds |
| abstract | Described are novel water soluble photochromic naphthopyran and benzopyran compounds having an alkylaminoalkylamino group on the naphtho- or benzo-portions and/or pyran portions thereof. Theses compounds may be represented by one of graphic formulae (1) or (2) or (3) wherein R1 is an alkylaminoalkylamino group. Articles such as ophthalmic lenses or other plastic transparencies and coating compositions such as paints and inks that incorporate the novel water soluble compounds are also described. |
