Title:
SURFACE PROTECTIVE FILM, METHOD FOR PRODUCING SURFACE PROTECTIVE FILM, AND OPTICAL MEMBER
Document Type and Number:
Japanese Patent JP2016102148
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a surface protective film which is capable of suppressing lifting and peeling, is excellent in shear force, and is capable of achieving antistatic properties and temporal stability of a peeling electrification voltage, a method for producing the surface protective film, and an optical member using the film.SOLUTION: The surface protective film includes a substrate having a first surface and a second surface, an antistatic layer provided on the first surface of the substrate, and a pressure-sensitive adhesive layer formed of a pressure-sensitive adhesive composition on the second surface of the substrate. The antistatic layer is formed of an antistatic agent composition which contains a polyaniline sulfonic acid as a conductive polymer component, a polyester resin as a binder, and an isocyanate-based crosslinking agent as a crosslinking agent. The pressure-sensitive adhesive composition contains a (meth)acrylic polymer which contains at least 50-99.9 mass% of a (meth)acrylic monomer having a 1-14C alkyl group and 0.05-25 mass% of a nitrogen-containing monomer as monomer components.SELECTED DRAWING: None
