Embodiment 1

[0101] 1. Preparation of Coating Solution of Pressure-Sensitive Adhesive Composition

[0102] 100 parts by mass of an addition reaction silicone resin (manufactured by Shin-Etsu Chemical Co., Ltd., product name "KS-847H") as a main ingredient of a silicone pressure-sensitive adhesive, 5.0 parts by mass of an organic Silicone resin (manufactured by DowCorning Toray Co., Ltd., product name "SD-4584"), 1.5 parts by mass of platinum catalyst (manufactured by DowCorning Toray Co., Ltd., product name "SRX 212CATALYST"), 0.5 parts by mass of Potassium N,N-bis(fluorosulfonyl)imide (K + FSI - ), and 0.5 parts by mass of tetraethylene glycol dimethyl ether as a dispersant were mixed, diluted with methyl ethyl ketone, and this was used as a coating liquid of a pressure-sensitive adhesive composition.

[0103] 2. Fabrication of protective sheet

[0104] The pressure-sensitive adhesive obtained in the above process was coated on one side of a PET film (manufactured by TOYOBO CO., LTD., ...

Embodiment 2～5

[0106] A protective sheet was produced in the same manner as in Example 1, except that the blending amounts of the antistatic agent and the dispersant were changed to those shown in Table 1 in preparation of the coating liquid of the pressure-sensitive adhesive composition.

Abstract

The present invention provides an anti -static organic silicon pressure sensitivity adhesive composition with high transparency and excellent substrate material, as well as high transparency, high transparency, substrate film and voltage -sensitive adhesive layer.Protective film.Anti -static organic silicon -sensitive adhesive composition provided by the present invention contains: organic silicon voltage sensitivity adhesives and antistatic agents. Among them, antistatic agents are ionic compounds formed by pineral ions and cations.Carbon atoms.

Description

technical field [0001] The present invention relates to a protective sheet for protecting devices, and an antistatic silicone pressure-sensitive adhesive composition usable for a pressure-sensitive adhesive layer of the protective sheet. Background technique [0002] In the past, for devices such as optical components and electronic components, in order to prevent damage to the surface during processing, assembly, inspection, etc., the surface of the device was sometimes pasted with a base film and a pressure-sensitive adhesive layer. protection sheet. When the protection is not required, the protective sheet is peeled off from the device, but at this time, static electricity may be generated by peeling off the static electricity. [0003] If static electricity is generated, dust or dust in the air will adhere to the device, resulting in a bad condition of the device. Therefore, in order to avoid the generation of static electricity, it is required to impart antistatic pro...
