In addition, if it is an optical member such as a polarizing plate, if it is directly applied to the liquid crystal with a large amount of static electricity, the alignment of the liquid crystal molecules will be lost, or a defect in the panel will occur.

Abstract

The invention provides a novel surface protection film, which is capable of achieving sufficiently high antistatic characteristics and wettability, and furthermore, has excellent reworkability (peelability). This surface protection film having a base material layer and an adhesive layer contains an ionic liquid or an alkali metal salt in the adhesive layer.

Description

technical field [0001] The invention relates to a surface protection film. The surface protection film of the present invention has a base material layer and an adhesive layer, and can be used for applications such as sticking to the surface of a display member or an image recognition member to protect the surface. Background technique [0002] On the surface of a display member or an image recognition member, a surface protective film may be bonded in order to prevent damage, contamination, etc. of the surface. [0003] In many cases, such a surface protection film is attached manually. When bonding is performed manually in this way, air bubbles tend to be trapped between the adherend and the surface protection film. [0004] In the case of bonding the adherend and the surface protection film manually, as a technique to prevent air bubbles from being trapped between the adherend and the surface protection film, it has been proposed to add an additive to the adhesive layer...
