The optical switching properties of a photochromic spirooxazine compound in retrofit polyester film and in poly(vinyl butyral) have been measured. The light fatigue resistance of these two optical switching elements were tested by an accelerated method. The length of photochromic activity of the optical switching elements can be improved by various organonickel and hindered amine light stabilizers. The effectiveness and optimal concentration for each light stabilizer in these host materials has been determined. These two types of light stabilizers act synergistically in improving the light fatigue resistance of the optical switching elements significantly. 14 refs., 2 figs., 3 tabs.
