Problems solved by technology

For example, when it is used for an optical film with irregularities on the surface such as a polarizing plate after anti-glare treatment to prevent glare, the adhesive layer cannot meet the irregularities on the surface of the optical film and bubbles are mixed, or the optical film and The bonding area of ​​the adhesive is reduced to reduce the adhesive force, and there will be problems of separation or peeling of the surface protection film during use

Embodiment 1

[0078] (manufacture of surface protection film)

[0079] With 5 parts by weight of addition reaction polysiloxane (product name is SRX-345, manufactured by Dow Corning Toray Co., Ltd.), 0.75 parts by weight of N-butyl-4-methylpyridinium hexafluorophosphate , 95 parts by weight of toluene and ethyl acetate as a 1:1 mixed solvent, 0.05 parts by weight of platinum catalyst (product name is SRX-212, manufactured by Dow Corning Toray Co., Ltd.) are mixed together and stirred to prepare The paint used to form the release agent layer of Example 1 was prepared. Using a Meller rod, the paint for forming the release agent layer of Example 1 was applied to the surface of a polyethylene terephthalate film having a thickness of 38 μm so that the thickness after drying was 0.2 μm. , and dried in a hot air circulation oven at 120° C. for 1 minute to obtain the release film of Example 1. On the other hand, 30 parts by weight of an acrylate copolymer having a weight average molecular weight ...

Embodiment 2

[0081] Except having applied the paint for forming the release agent layer of Example 1 so that the thickness after drying might become 0.1 micrometer, it carried out similarly to Example 1, and obtained the surface protection film of Example 2.

Embodiment 3

[0083] Except that SRX-211 (product name) manufactured by Dow Corning Toray Co., Ltd. was used as the addition reaction polysiloxane of Example 1, the same operation was carried out as in Example 1, and the surface protection of Example 3 was obtained. membrane.

Abstract

The invention provides a surface protection film and an optical component attached with the same. The surface protection film is available for an optical film with a concave-convex surface, less pollutes a to-be-adhered body, will not degrades the low ability to contaminate the to-be-adhered body and is provided with excellent anti-stripping static performance. A binder layer (2) is formed on a single face of a base material film (1) formed by transparent resin. A stripping film (5) with a stripping agent layer (4) is attached to the binder layer (2). The stripping agent layer (4) is laminated on the single face of a resin film (3), so the stripping film (5) is formed. The stripping agent layer (4) contains the stripping agent with dimethyl polysiloxane being as the main component, and anti-static agent which will not react with the stripping agent. When the anti-static agent component shifts from the stripping film (5) towards the binder layer (2), stripping static voltage can be reduced when the above binder layer (2) is stripped from the to-be-adhered body.

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, the present invention provides a surface protection film with less contamination to an adherend, a surface protection film having excellent anti-peeling static performance without deterioration over time, and a product bonded with the surface protection film. optics. 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 contamination and scratches in subsequent steps. In ...
