表面保護フィルム、及び、光学部材
Document Type and Number:
Japanese Patent JP6867788
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a surface protective film which is excellent not only in anchoring property to an antistatic layer of an adhesive layer and but also in peeling antistatic property and stain resistance, and to provide an optical member protected by the surface protective film.SOLUTION: A surface protective film has an antistatic layer on at least one surface of a base material and has an adhesive layer formed of an adhesive composition containing a (meth)acrylic polymer on a surface of the antistatic layer opposite to a surface thereof in contact with the base material, where the antistatic layer is formed of an antistatic agent composition containing a water-soluble conductive polymer and/or a water dispersible conductive polymer, a polyester resin as a binder, and a surface resistance value of the antistatic layer is 1.0×10Ω/sq. or less, and distribution (Mw/Mn) of molecular weight of the (meth)acrylic polymer is 6 or less. In the surface protective film, the base material is a polyester film.SELECTED DRAWING: None
