Embodiment 1

[0087] (manufacture of surface protection film)

[0088] 5 parts by weight of addition reaction polysiloxane (product name is SRX-345, manufactured by Dow Corning Toray Co., Ltd.), 0.3 parts by weight of polyether-modified polysiloxane Siloxane (product name SH8400, manufactured by Dow Corning Toray Co., Ltd.), 1 part by weight of N-butyl-4-methylpyridinium hexafluorophosphate as an ionic compound with a melting point of 48°C, 95 The toluene of weight part and ethyl acetate are the mixed solvent of 1:1, the platinum catalyst of 0.05 weight part (product name is SRX-212, manufactured by Dow Corning Toray Co., Ltd.) are mixed together and stirred and mixed, prepared to form Coating for the release agent layer of Example 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 circul...

Embodiment 2

[0090] Except having set the thickness after drying of the coating material which forms the release agent layer of Example 1 to 0.1 micrometer, it carried out similarly to Example 1, and obtained the surface protection film of Example 2.

Embodiment 3

[0092] 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 a product named KS-352A manufactured by Shin-Etsu Chemical Co., Ltd., and used 1-methyl-3-ethylimidazolium hexafluorophosphate as an ionic compound with a melting point of 62°C instead of N-butyl - 4-Methylpyridinium hexafluorophosphate was carried out in the same manner as in Example 1 except for the above, to obtain the surface protection film of Example 3.

Abstract

The invention provides a surface protection film having little pollution to an adhered object, low pollution unchanged along with the time, and good anti-stripping static performance without degradation, and an optical component attached with the surface protection film. The surface protection film (10) is provided with an adhesive layer (2) on a single surface of a substrate film (1) formed by transparent resin, and a stripping film (5) adhered with a stripping agent layer (4) is adhered to the adhesive layer (2), wherein the stripping film (5) is formed by forming the stripping agent layer (4) on the single surface of a resin film (3). The stripping agent layer (4) comprises the stripping agent adopting dimethyl polysiloxane as the main component, a polysiloxane compound that is liquid below 20 DEG C and a resin composition of an ionic compound having a melting point of 30-80 DEG C. The adhesive layer (2) is an acrylic acid type adhesive layer.

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 that has less contamination to an adherend, does not deteriorate over time, and has excellent anti-peeling electrostatic performance, and an optical component bonded with the 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 contamination and scratches in subsequent steps. In order to imp...
