The polymer matrix effect on the photochromic reactions of spirooxazines was investigated. Four polymers of different polarity, poly(vinyl butyral), polystyrene, styrene/allyl alcohol copolymer, and 1, 2-polybutadiene were used as matrices. In the polar matrices, absorption maxima of colored form of spirooxazines were shifted to red and photochromic reaction rates of spirooxazines decreased remarkably. These phenomena were caused by stabilization of metastable colored spirooxazine due to interaction with hydroxyl group of polymer.
