ABSTRACT:
Archival materials including paper manuscripts are preserved by a thin protective polymer film applied to the surface of the item by plasma polymerization of an organic monomer gas in a high frequency glow discharge. The polymer film protects the item against humidity and prevents widening of stroke lines due to ink spreading on the document. Microorganism growth is stopped by pretreatment of the document in a monoatomic gas plasma.
