| Abstract: | Summaries. The degradative effect of UV light on paper is well known. In the presence of zinc oxide and high humidity, the effect is increased significantly. Since the original diethyl zinc paper deacidiflcation process left zinc oxide as an alkaline reserve, ways to inhibit accelerated degradation were sought. The presence of 0.05% iodide in the paper is sufficient to inhibit completely the accelerated degradation with little effect on brightness. Also effective is modifying the diethyl zinc process to leave zinc carbonate rather than zinc oxide as the alkaline reserve. Books treated by the modified process do not show increased light sensitivity but show photodegradation rates similar to or slightly less than those of untreated books. |
