Abstract
A layered material containing a buffer and optionally containing an adsorbent. The material may also include a vapor barrier. The material is used for the preservation of archival documents and objects. A container configured to permit the long term storage of documents without slippage of the documents or resulting deformation may also be made from the material.
Claims27
A layered archival preservation material for the preservation of archival documents and objects, said layered material comprising:
- a first layer comprising an alkaline buffer or a deacidifying agent;
- a second layer comprising an alkaline buffer or a deacidifying agent;
- a vapor barrier positioned between said first layer and said second layer, wherein said vapor barrier prevents the passage of vapor through said layered archival preservation material, and wherein either said first layer or said second layer additionally contains an adsorbent.
A preserved archival document or object comprising an archival document or object in combination with a layered preservation material, such that said archival document or object is placed in contact with or in close proximity to said layered preservation material, and wherein said layered material comprises a first layer having an alkaline buffer or a deacidifying agent, a second layer having an alkaline buffer or deacidifying agent, and a vapor barrier positioned between said first and said second layer, wherein said vapor barrier layer prevents the passage of vapor through said layered material and wherein either said first layer or said second layer further comprises an adsorbent.
A matting board for the preservation of an archival document or object, said board comprising
- a first layer having an alkaline buffer or a deacidifying agent;
- a second layer having an alkaline buffer or deacidifying agent;
- a vapor barrier positioned between said first and said second layer, wherein said vapor barrier layer prevents the passage of vapor through said board and
- wherein either said first layer or said second layer further comprises an adsorbent.
A mounting board for the preservation of an archival document or object, said board comprising
- a first layer having an alkaline buffer or a deacidifying agent;
- a second layer having an alkaline buffer or deacidifying agent;
- a vapor barrier positioned between said first and said second layer, wherein said vapor barrier layer prevents the passage of vapor through said board and
- wherein either said first layer or said second layer further comprises an adsorbent.
