Used in the early 1930s mostly for small gauges, then was widely used post 1950s to replace nitrate base. Often refered to as "safety film". Acetate" base in modern exhibition settings usually refers to '''triacetate''' base. '''Diacetate''' was used on some early safety film, but you won't see it very often under normal circumstances (whatever THOSE are!). Older acetate prints tend to be more brittle and prone to warping as they lose moisture. Acetate is thicker and tends to break when stressed. | Used in the early 1930s mostly for small gauges, then was widely used post 1950s to replace nitrate base. Often refered to as "safety film".
