Vinegar Syndrome  

"Vinegar Syndrome" is a term used to describe the chemical reaction that goes on during the deterioration of cellulose triacetate film support. When cellulose triacetate begins to decompose, "deacetylation" occurs and the acetate ion reacts with moisture to form acetic acid producing a vinegar odor when a can is opened. Once the reaction is started, it cannot be stopped. -Information extracted from a paper that was presented at the 1992 AMIA Conference on December 10, 1992, by Dr. Tulsi Ram.

Molecular Sieve Acid Scavenger  

Molecular Sieve is a promising new technology developed by Eastman Kodak Company that has the ability to retard the vinegar syndrome reaction. Simply stated, the inclusion of Molecular Sieve with processed motion picture film in a sealed container has the ability to extend the life of the dye images and film support beyond that which is currently considered normal.

Storage Information  

Descriptions of storage conditions, their variations, and general considerations and comparisions; storage of raw stock, the effect of ambient background radiation on raw stock, radiation from airport x-ray equipment, and more.

Storage Room  

Explanations of appropriate storage facility characteristics, including relative humidity, temperature, tropical conditions, air conditioning, dehumidification, dessication, chemical contamination, water damage, extended storage considerations, and more.

Storage and Handling of Processed Nitrate Film  

Nitrate base, the pioneer of motion picture film bases, retired from our cameras and laboratories about 1951-52. Still, its very long shadow of distinguished commercial motion pictures and film records haunts many film vaults. Nitrate base films must be handled with informed care.  

Handling of Processed Film  

Detailed information about room cleanliness, inspection methods, film damage, emulsion deterioration, common repairs, damage evaluation, film cleaning, lubrication, and more.

Storage and Handling of Unprocessed Film  

Information on maintaining film quality with refrigeration, frozen film, Newton's rings and ferrotyping, effects of humidity and contaminants, and airport x-ray fog. Technical Information Bulletin #TIB5202.

Storage and Handling of Processed Film  

Discusses effects of humidity on processed film, Newton's rings and ferrotyping, effects of contaminants, extended storage (10 years or more), and airport x-ray fog. Technical Information Bulletin #TIB5203.
