ABSTRACT:
Light fatigue resistant, non-orange, photochromic mercury complexes of asymmetrical diarylthiocarbazones for use in making photochromic sunglass lenses, ski goggles, and the like. The compounds comprise the class of mono and bis mercury diarylthiocarbazonates wherein one aryl group is an aryl group substituted at the ortho position with an electron withdrawing group such as CF.sub.3 and the other aryl group is different from the first and can comprise variously substituted or unsubstituted phenyl or naphthyl groups.
