Lignin, an organic compound found in wood pulps, has for many years been restricted in U.S. and international stan-dards for permanent paper. While history has shown that many papers containing lignin could deteriorate rapidly, the same may not be true for alkaline paper made from modern high-yield pulps, a growing component of the world's pulp production.
Additional research is needed to establish the effects of lignin on paper permanence.
This research project seeks to provide a sound basis for the development of a Canadian permanent paper standard. Project sponsors from the federal government include Industry Canada, the Department of Canadian Heritage, the National Archives and the National Library. Industry participants include DuPont Canada, Fibreco Pulp, Louisiana Pacific, Millar Western Pulp, Quesnel River Pulp, Tembec Inc. and Slave Lake Pulp. The project is anticipated to end by November 1996. The National Library of Canada.
