Abstract

The present invention provides an optical film that can be used even with irregularities on the surface, has less contamination to the adherend, has no time-dependent change in the low-contamination property of the adherend, and has excellent peeling resistance that does not deteriorate over time A surface protection film with electrostatic properties and an optical part using the surface protection film. The surface protection film (10) has an adhesive layer (2) formed on one side of a base film (1) made of a transparent resin, and a release agent layer ( 4) The release film (5), the release film (5) is formed by laminating a release agent layer (4) on one side of the resin film (3), and the release agent layer (4) contains a long-chain alkyl-containing resin A release agent as the main component and an antistatic agent composed of an ionic compound that does not react with the release agent, the antistatic agent component transfers from the release film (5) to the surface of the adhesive layer (2), reducing the adhesion The peeling static voltage when the binder layer (2) is peeled from the adherend.

Description

technical field

[0001] The present invention relates to a surface protection film bonded to the surface of optical components (hereinafter, sometimes referred to as "optical film") such as polarizing plates, retardation plates, and lens films for displays. More specifically, to provide a surface protection film with less contamination to an adherend, and further to provide a surface protection film that does not deteriorate over time (does not deteriorate with time) and has excellent anti-peeling electrostatic performance, and An optical part bonded with this surface protection film. Background technique

[0002] At present, when manufacturing and transporting optical films such as polarizing plates, retardation plates, lens films for displays, anti-reflection films, hard coat films, transparent conductive films for touch panels, and optical products such as displays using them, A surface protective film is bonded to the surface of the optical film to prevent surface contam...
