The decay of fluorescence on a range of commercially available papers was investigated by exposing them to a 1KW tungsten lamp for a total of 10 hours, with the samples removed for measurement at regular intervals. The results indicated that FWA decay is more rapid on papers with higher FWA efficacy. Only the papers with minimal FWA efficacy reached a plateau after which there was no further significant decay
