Embodiment 1

[0087] Manufacture of release film for adhesive film

[0088] Addition-reactive silicone (manufactured by Dow Corning Toray Co., Ltd., trade name: SRX-345) 3 parts by weight, polyether-modified polysiloxane (manufactured by Dow Corning Toray Co., Ltd., trade name: SH8400) 0.1 parts by weight 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 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.

[0089] Manufacture of Binder Compositions

[0090] Add 90 parts by weight of 2-ethylhexyl acrylat...

Embodiment 2

[0094] 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

[0096]100 parts by weight of the adhesive composition of Example 1 and 1.5 parts by weight of lithium bis(trifluoromethanesulfonyl)imide as an antistatic agent were stirred and mixed 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 invention provides release film for forming an adhesive film with low pollution on an article to be adhered, further provides a release film for forming adhesive film with an excellent release static prevention property, and the adhesive film using the release film. The release film (5) for the adhesive film can protect the binder layer (2) of the adhesive film with the binder layer (2) at least stacked on a single layer of the substrate film (1), and can be released, wherein the release film is formed by stacking a release agent layer (4) at least on a single surface layer of a resin film (3), and is adhered on the surface of the binder layer (2) by the release agent layer (4), 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.

Description

technical field [0001] 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 [0002] Conventionally, release films (also called "release films") have been used in various applications such as protective films for protecting the surface of adhesive layers. As a general use of the release film, for example, the release film is attached to an adhesive film with an adhesive layer formed on one side of the substrate, or to an adhesive layer without a substrate to protect the adhesive. agent layer. The adhesive film with the peeling film attached to the adhesive layer is stored...
