Abstract
A reflection-preventive layer composed of a specific polyfluoro(meth)acrylate is formed on one or both of the surfaces of a transparent film of a cellulose derivative. In this reflection-preventive pellicle film, the minimum light transmission in wavelengths of 350 to 450 nm is improved and the average light transmission is improved, and the adhesion of the reflection-preventive layer to the cellulose derivative layer is excellent.
