Abstract
Numerous potential triazine-stabilizers were synthesized to prolong the life of an azo dye. The effect of these compounds in reducing photofading was examined in cellulose acetate film. The simple use of UV absorbers or radical scavengers was not necessarily useful in improving the light fastness of the dye. The triazine-stabilizers containing a number of different types of stabilizing fragments, however, markedly suppressed the photofading of the dye. It was proposed that nickel complexes of multifunctional triazine-stabilizers may be used as effective stabilizers in the fading of dyes.
