EFFECTS OF ENCLOSURE PAPERS AND PAPERBOARDS CONTAINING LIGNINS ON PHOTOGRAPHIC IMAGE STABILITY

DANIEL M. BURGE, JAMES M. REILLY, & DOUGLAS W. NISHIMURA


ABSTRACT—The photographic activity test (PAT) was used to quantify the effects of lignin-containing papers and boxboards on photographic image stability. For papers in direct contact with photographs, as lignin content increased, both gelatin staining and silver image interaction increased. Tnhese effects were somewhat mitigated by the inclusion of calcium carbonate buffering in the paper. For boxboards surrounding but not in direct contact with photographs, the effects were only slightly mitigated by the air space between lignin-containing board and test detectors. It was also determined that other wood components, collectively known as extractives, were also reactive with silver images. These extractives are, however, simultaneously removed with lignin during pulp delignification.
