Title: (EN) Photochrome diaryl-3H-naphthopyrane
Abstract:
(EN) The disclosure relates to a photochromic compound with diaryl-3H-naphthopyrane structure which in position 8 has a heterocycle linked via a nitrogen atom. The heterocycle can also have a hindered amine light stabilizer (HALS) compound as substituent or can take the form of a HALS compound. Also described is a photochromic compound with diaryl-3H-napththopyrane structure with a HALS compound in position 8 linked via a nitrogen atom and an alkyl bridge.
