Photofading of crystal violet (CV) in nylon and polyester films is suppressed with the progress of decay. Photofading of the dye in polymer substrates is explained on the basis of two models: a distribution of photochemical reactivity sites for the dye, and a bimolecular reaction mechanism for fading. Simulation results using the first model are compatible with experimental results for nylon, whereas the simulation derived by combining both models corresponds well to the photofading behavior of CV in polyester. Results from the fluorescence measurements by pulse fluorometry also support the first model.
