Abstract
A preservation article for the preservation of an archival article, wherein the preservation article includes a molecular sieve which is organophilic, hydrophobic or acid-resistant. A method of preserving an archival article which involves providing a preservation article in proximity to an archival article, wherein the preservation article includes a molecular sieve which is organophilic, hydrophobic or acid-resistant. The preservation article may be coated on or incorporated into a container, a packaging material, a support for an archival article or the archival article itself.
Claims63
A preserved archival article comprising an archival article in combination with a preservation article, such that said archival article is placed in contact with or in close proximity to said preservation article and wherein said preservation article comprises, contained within a paper material:
- a molecular sieve which is organophilic, hydrophobic, or acid-resistant to selectively remove chemical components from the environment of the archival article to preserve the archival article.
A preserved archival article comprising an archival article in combination with a preservation article, such that said archival article is placed in contact with or in close proximity to said preservation article and wherein said preservation article comprises, contained within a paper material:
- a first layer comprising a substrate and at least one alkaline buffer or deacidifying agent in said substrate and
- a second layer comprising a substrate and a molecular sieve which is organophilic, hydrophobic, or acid-resistant in said substrate,
- wherein said alkaline buffer or deacidifying agent neutralizes or removes acidic components from the environment of the archival article and wherein said molecular sieve removes chemical components from the environment of the archival article.
