No, but an atmosphere of krypton will prevent moisture from making acid from any acid anhydrides, such as sulfur dioxide, that may be present in the paper.

Basic anhydrides are metal oxides (any metal ion bonded to the oxide ion) like MgO or Na2O. Metal oxides strip one of the hydrogens away from water, leaving an OH ion.
