Abstract

Described are novel photochromic six-membered heterocyclic-fused naphthopyran compounds, examples of which are naphthopyran compounds having a substituted or unsubstituted six-membered heterocyclic group fused to one side of the naphtho portion of the naphthopyran and having certain substituents at the position ortho to the oxygen atom of the naphthopyran ring. These compounds may be represented by graphic formula (A). Also described are polymeric organic host materials that contain or that are coated with such compounds or combinations thereof with complementary photochromic compounds, e.g., certain other naphthopyrans, benzopyrans, and spiro (indoline)type compounds.
