this is a direct quote from the light impressions (good resource for
archival supplies) website www.lightimpressionsdirect.com:
"What is the difference between buffered and non-buffered storage papers and
mat board?
Buffered paper and board have calcium carbonate added to raise the pH level
to 8.0-8.5. The buffering agent neutralizes acids that could potentially
harm your work. They work best for the storage and display of Black & White
photos and artwork on paper. Non-buffered paper and board have a pH level
between 7.0-7.5. There is no buffering agent, since it may adversely affect
some materials, causing color shifts or changes. Non-buffered materials are
intended for use with albumen, cyanotype, dye transfer, and color prints
(chromogenic), as well as protein textiles."
hope this helps...
