Safety film
Photographic film called safety film is made with an acetate base, chemically either cellulose diacetate, cellulose acetate propiarate, cellulose acetate butyrate, or cellulose triacetate. Beginning in the 1920s, it replaced nitrocellulose, or nitrate, film bases used previously as the film stock used in both amateur and professional applications.

Cellulose triacetate films are still in use today for some applications, but have largely been replaced with polyester bases that are more stable and more durable.
