Photochromic Dichroic Articles

Abstract: Provided are photochromic optical articles including an optical substrate and an at least partial anisotropic layer disposed on the at least a portion of the surface of the substrate. The anisotropic layer includes an anisotropic polymer; a photochromic-dichroic dye, a photochromic dye, or combination thereof; a mesogenic hindered amine light stabilizer; and a mesogenic antioxidant. Provided are photochromic coated articles including a substrate and an anisotropic coating layer on at least a portion of the surface of the substrate. The anisotropic coating layer is formed from a polymerizable composition including a polymerizable anisotropic material; a photochromic-dichroic dye, a photochromic dye, or combination thereof; a mesogenic hindered amine light stabilizer; and a mesogenic antioxidant.
