Abstract
Recent advances in the photostabilization of mechanical pulp suggest that the use of additive mixtures may provide optimal protection against brightness reversion. Some of the most promising additive mixtures reported in the literature include the use of a UV absorber, such as 2,4-dihydroxybenzophenone, and a radical scavenger. The mechanistic basis of this synergistic effect was explored by monitoring the photostability of benzophenone during brightness reversion. These studies demonstrated that the benzophenone additives were stable under the initial photolysis conditions. The use of mercapto derivatives of benzophenone did not enhance the photostabilization effect, suggesting that the thiol additive and UV absorber need not be in close association with each other for the observed photostabilization effects to occur.
