Stabilized matrix for photochromic articles |
| abstract |
A stabilizing matrix for photochromic compounds is disclosed in which a functionalized hindered amine light stabilizer capable of reacting with an isocyanate group is linked to the polymer backbone by a convalent bond to form a grafted structure. The resultingg matrix is characterized by having a stabilizing effect on the photochromic dye, in particular, spirooxazines. Preferred specific articles of the invention are photochromic organic lenses. |
