Embodiment 1

[0088] Manufacture of release film for adhesive film

[0089] 3 parts by weight of addition reaction silicone (manufactured by Dow Corning Toray Co., Ltd., trade name: SRX-345), 0.1 parts by weight of polyether-modified polysiloxane (manufactured by Dow Corning Toray Co., Ltd., trade name: SH8400) parts, 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 Dow Corning Toray Co., Ltd., trade name: SRX-212) were stirred and mixed to prepare the Stripper layer of paint. On the surface of polyethylene terephthalate with a thickness of 38 μm, the coating material for the release agent layer of Example 1 was coated with a wire bar so that the thickness after drying was 0.1 μm, and hot air at 120° C. was used. The peeling film for adhesive films of Example 1 was obtained by drying in a circulating oven for 1 minute.

[0090] Manufacture of Binder Compositions

[0091] In a four-necked flask with a ...

Embodiment 2

[0095]100 parts by weight of the binder composition of Example 1 and 0.1 part by weight of lithium perchlorate as an antistatic agent were stirred and mixed to prepare the binder composition of Example 2 containing an antistatic agent. Except for using the adhesive composition of Example 2 instead of the adhesive composition of Example 1, by the same method as Example 1, the adhesive film bonded with the release film for the adhesive film of Example 2 was obtained. Adhesive film.

Embodiment 3

[0097] 100 parts by weight of the adhesive composition of Example 1 was stirred and mixed with 1.5 parts by weight of bis(trifluoromethanesulfonyl)imide lithium as an antistatic agent to produce the adhesive composition of Example 3 with an antistatic agent. agent composition. Except for using the adhesive composition of Example 3 instead of the adhesive composition of Example 1, by the same method as Example 1, the adhesive film bonded with the release film for the adhesive film of Example 3 was obtained. Adhesive film.

Abstract

The present invention provides a release film for an adhesive film capable of reducing the contamination of a substrate and, more specifically, to a release film for an adhesive film capable of having excellent exfoliation antistatic performance. The release film (5) for an adhesive film capable of protecting and delaminating an adhesive layer (2) of an adhesive film in which the adhesive layer (2) is laminated on at least one side of a base film (1) is formed by laminating a release agent layer (4) on at least one side of a resin film (3) and is attached on the surface of the adhesive layer (2) by interposing the release agent layer (4). The release agent layer includes a release agent containing dimethyl polysiloxane as a main component and a silicon-based compound which is liquid at 20°C.

Description

[0001] This application is a divisional application of an application with a filing date of May 16, 2013, an application number of 201310181917.1, and an invention titled "A release film for an adhesive film and an adhesive film using the release film for an adhesive film". technical field [0002] The present invention relates to a release film for an adhesive film bonded to the surface of an adhesive layer of an adhesive film. More specifically, the present invention provides a release film for an adhesive film for realizing an adhesive film with less contamination to an adherend, and further provides an adhesive for realizing an adhesive film having excellent anti-peeling static performance. Conjunctiva with peel-off membrane. Background technique [0003] Conventionally, a release film (also referred to as a "release film") has been used in various applications such as a protective film for protecting the surface of an adhesive layer. As a general use of the release fil...
