摘要

PROBLEM TO BE SOLVED: To provide a coating film having excellent antistatic property and durability and exhibiting excellent characteristics when used as a protective film for an optical member. SOLUTION: The polyester film for a surface protective film comprises a coated layer containing an antistatic polymer compound having a nitrogen-containing five-membered ring-shaped quaternary ammonium salt and a hydroxy group-containing acrylate as repeating units on one side of a polyester film. The polyester film for optical member surface protection has a fine adhesive layer on a surface at the opposite side of the coated layer of the film. COPYRIGHT: (C)2009,JPO&INPIT
