Embodiment 1

[0088] Manufacture of Binder Compositions

[0089] Add 90 parts by weight of 2-ethylhexyl acrylate and 10 parts by weight of methoxypolyethylene glycol (400) monomethacrylate , 3 parts by weight of 2-hydroxyethyl acrylate, 0.2 parts by weight of 2,2'-azobisisobutyronitrile as a polymerization initiator, 154 parts by weight of ethyl acetate, stir the content while introducing nitrogen, and heat up to 65 ℃. Furthermore, a polymerization reaction was performed at a temperature of about 65° C. for 6 hours to obtain a polyoxyalkylene group-containing acrylic polymer. 100 parts by weight of the obtained polyoxyalkylene-containing acrylic polymer was stirred and mixed with 0.1 parts by weight of lithium perchlorate as an antistatic agent, thereby manufacturing the binder composition of Example 1 (solid content 40% ).

[0090] Manufacture of surface protection film

[0091] Addition-reactive silicone (manufactured by Dow Corning Toray Co., Ltd., trade name: SRX-345) 3 parts by wei...

Embodiment 2

[0093] Using 1.5 parts by weight of lithium bis(trifluoromethanesulfonyl)imide to replace 0.1 parts by weight of lithium perchlorate in the binder composition of Example 1, the binder composition of Example 2 (solid composition 40%).

[0094] Except having used the adhesive composition of Example 2 instead of the adhesive composition of Example 1, the surface protection film of Example 2 was obtained by the method similar to Example 1.

Embodiment 3

[0096]3 parts by weight of addition-reactive silicone (manufactured by Dow Corning Toray Co., Ltd., trade name: SRX-211), and 0.1 parts by weight of polyether-modified polysiloxane (manufactured by Shin-Etsu Chemical Co., Ltd., trade name: KF352A) 97 parts by weight of a 1:1 mixed solvent of toluene and ethyl acetate, and 0.03 parts by weight of a platinum catalyst (manufactured by Toray Dow Corning Co., Ltd., trade name: SRX-212) were stirred and mixed to form the compound of Example 3. Stripper layer of paint. On the surface of a polyethylene terephthalate film with a thickness of 38 μm, the coating material for the release agent layer of Example 3 is coated with a wire bar so that the thickness after drying becomes 0.1 μm, and then hot air at 120° C. is passed. The peeling film of Example 3 was obtained by drying in a circulating oven for 1 minute.

[0097] Except having used the release film of Example 3 instead of the release film of Example 1, the surface protection fil...

Abstract

The invention provides a surface protective film which has low pollution on an adhered object , will not be degradated over time and has an excellent release static prevention property, and a optical component attached with the surface protection film. A binder layer (2) is formed on a single surface of a transparent substrate film, the surface protection film (10) with a release film is attached on the binder layer (2), the binder film (2) contains an antistatic agent, the release film (5) is formed by stacking a release agent layer (4) on the single surface layer of a resin film (3), and the release agent layer (4) contains a release agent using dimethyl polysiloxane as a main component, and a silicon compound which is a liquid under 20 DEG C. The binder layer (2) is formed by a (methyl) acrylic copolymer copolymerized with a compound with a polyoxyalkene group, or is formed by the (methyl) acrylic copolymer mixed with the compound with the polyoxyalkene group.

Description

technical field [0001] The present invention relates to a surface protection film bonded to the surface of optical components (hereinafter, also 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 that does not contaminate an adherend less, does not deteriorate over time, and has excellent anti-peeling static performance, and an optical component using the surface protection film. Background technique [0002] When manufacturing and transporting optical products such as displays using optical films such as polarizing plates, retardation plates, lens films for displays, anti-reflection films, hard coat films, and transparent conductive films for touch panels, the above-mentioned The surface of the optical film is bonded with a surface protection film to prevent surface contamination or scratches in subsequent processes. In the visual inspection d...
