what is the problem of acetate films?

In Japan, most of microfilm created prior to 1990 has a backing made of acetate plastic. These acetate films are subject to an additional kind of degradation called "vinegar syndrome". When the backing on acetate films begins to degrade it releases acetic acid. This is exactly the kind of acid that makes vinegar smell and taste like vinegar. And most of acetate films already got "vinegar syndrome. The release of the acid into the air begins a rapidly accelerating process of film degradation. Now, we are looking at more and more vinegar syndrome degradation.
