Substrate for surface protective film, method for producing the substrate, surface protective film using the substrate, and optical film with surface protective film |
| abstract |
An object of the present invention is to provide a substrate for a surface protective film having excellent flexibility or bending resistance and capable of favorably suppressing light leakage, coloring and rainbow unevenness during an optical inspection. A substrate for a surface protective film of the present invention is composed of a film containing a polymer alloy of a fluorene ring-containing polyester and an aromatic polycarbonate, has an in-plane retardation Re (550) of 30 nm or less, and has an MIT test. Is 500 times or more before breaking. The method for producing a substrate for a surface protective film of the present invention comprises forming a film-forming material containing a polymer alloy of a fluorene ring-containing polyester and an aromatic polycarbonate into a film, and sequentially biaxially stretching the formed film. Or it includes simultaneous biaxial stretching. [Selection diagram] None |
