Embodiment 1

[0091] (manufacture of antistatic surface protection film)

[0092]5 parts by weight of addition reaction polysiloxane (product name is SRX-345, manufactured by Dow Corning Toray Co., Ltd.), 0.15 parts by weight of polyether-modified polysiloxane Siloxane (product name is SH8400, manufactured by Dow Corning Toray Co., Ltd.), lithium perchlorate of 5 parts by weight is 10% ethyl acetate solution, toluene of 95 parts by weight and ethyl acetate are 1:1 Mixed solvent and 0.05 parts by weight of platinum catalyst (product name is SRX-212Catalyst (catalyst), manufactured by Dow Corning Toray Co., Ltd.) are mixed together and stirred and mixed to prepare the coating that forms the release agent layer of embodiment 1 . Using a Meller rod, the paint forming the release agent layer of Example 1 was coated on the surface of a polyethylene terephthalate film with a thickness of 38 μm so that the thickness after drying was 0.2 μm, and It dried for 1 minute in the hot-air circulation ove...

Embodiment 2

[0094] The antistatic surface protection film of Example 2 was obtained in the same manner as in Example 1 except that the thickness after drying of the paint forming the release agent layer of Example 1 was 0.1 μm.

Embodiment 3

[0096] As the addition reaction polysiloxane of Example 1, the product named SRX-211 manufactured by Dow Corning Toray Co., Ltd. (Dow Corning Toray Co., Ltd.) was used. The alkane used the product named KS-352A manufactured by Shin-Etsu Chemical Industry Co., Ltd., and used 10 parts by weight of bis(trifluoromethanesulfonyl)imide lithium as a 10% ethyl acetate solution to replace 5 parts by weight of perchlorate Lithium acid is a 10% ethyl acetate solution, and the same procedure as in Example 1 is performed except for the above, to obtain the antistatic surface protection film of Example 3.

Abstract

The invention provides a method for producing an antistatic surface protection film, and the antistatic surface protection film which produces less pollution on a bonded body, does not degrade gradually, and has an excellent anti-peeling static performance. The method produces the antistatic surface protection film (10) through the steps of forming a bonding agent layer (2) on a single surface of a substrate film (1) made of transparent resin, laminating a peeling agent layer (4) containing an antistatic agent on a single surface of a resin film (3) to form a peeling film (5), and bonding the peeling agent layer (4) onto the surface of the bonding agent layer (2), wherein the peeling agent layer (4) is composed of a peeling agent taking dimethyl polysiloxane as a main component, a polyorganosiloxane compound being liquid under 20 DEG C, and a resin composition of the antistatic agent.

Description

technical field [0001] The present invention relates to a method for producing an antistatic surface protective film bonded to the surface of optical components such as polarizing plates, retardation plates, and lens films for displays (hereinafter, sometimes referred to as "optical films"), and an antistatic surface protective film. More specifically, the present invention provides a method for producing an antistatic surface protection film that has less contamination to an adherend, does not deteriorate over time, and has excellent anti-static peeling performance, and an antistatic 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...
