Photochromic behaviour is a common characteristic in spiropyrans and spiro-oxazines as well as other photochromic materials. From a commercial point of view, the fatigue resistance of these compounds is the key property that largely determines whether they are likely to find any practical application. Various potential metal complexes were synthesised to improve the light fatigue resistance of spiropyrans. The protective effect of these compounds against the dark or photofading of photocoloured species was examined on the solid state. The zinc or nickel salts of 8-hydroxyquinoline-2-carboxylic acid and its derivatives were found to be very effective in stabilizing the coloured form of spiropyran.
