Cellulose acetate, first prepared in 1865, is the acetate salt of cellulose. Cellulose acetate is used as a film base in photography, and as a component in some adhesives.
Acetate movie film was introduced in the 1950s as a replacement for the unstable and inflammable cellulose nitrate film stock that had previously been standard.
Acetate photographic film deteriorates in the presence of oxygen to an unusable state, releasing acetic acid. This is known as "vinegar syndrome."
