In its crystalline form, spirooxazine does not usually exhibit photochromism. However, a crystalline spherulite spirooxazine film has been found to exhibit coloration upon irradiation with a continuous ultraviolet (UV) light and decoloration under dark conditions at room temperature, thereby indicating the occurrence of photochromism. The construction of different replicable microreliefs was successfully achieved by alternately irradiating with patterned UV light and heating the film to its melting point.
