Embodiment 1

[0104] In order to form an antistatic silicone release layer on one surface of a corona-treated polyester base film (Excell-50 μm, manufactured by Toray Advanced Materials Korea Inc.), based on 100 parts by weight of alkenyl poly Siloxane (manufactured by Dow Corning), 3 parts by weight of hydropolysiloxane (manufactured by Dow Corning), 2.5 parts by weight of conductive polymer resin (containing 0.5% by weight of poly(3,4-ethylene dioxythiophene) and 0.8% by weight of polystyrenesulfonic acid (molecular weight Mn=150000), and an aqueous dispersion with an average particle diameter of 50 nm), 10 parts by weight of an epoxy-based binder compound (manufactured by Esprix Technologies ), 50 ppm of chelated platinum catalyst (manufactured by DowCorning), and 0.2 parts by weight of ionic surfactant (dioctyl sulfosuccinic acid sodium salt) were mixed in water to produce an antistatic silicone release composition .

[0105] The produced antistatic silicone release composition was dil...

Embodiment 2

[0107] An antistatic silicone release film was produced in the same manner as in Example 1, except that 10 parts by weight of a conductive polymer resin was added based on 100 parts by weight of alkenylpolysiloxane.

Embodiment 3

[0109] An antistatic silicone release film was produced in the same manner as in Example 1, except that 2 parts by weight of a conductive polymer resin was added based on 100 parts by weight of alkenylpolysiloxane.

Abstract

The present invention provides an antistatic silicone release film which does not have a side effect caused by an electrostatic discharge when being peeled from an adhesive, as the film has an excellent antistatic function, and which has a stable release characteristic, as the film has excellent adhesion to a base material of a hardening layer, and the hardening layer has a high degree of crosslinking. The antistatic silicone release film includes a base film and a cured layer of an antistatic silicone release composition positioned on at least one side of the base film, wherein the cured layer includes an intensity ratio of silicon ions exhibiting silicone release properties and sulfur ions exhibiting antistatic properties ( Si- / S-) is achieved by an antistatic silicone release film comprising an antistatic region of less than 1 and a silicon release region of more than 10.

Description

technical field [0001] The following description relates generally to antistatic silicone release films, and more particularly to antistatic silicone release films that provide excellent antistatic properties when the film is removed from the adhesive without Electrostatic side effects, excellent adhesion between the cured layer and the substrate is obtained, and the cured layer has a high degree of cross-linking, thereby achieving stable release characteristics. Background technique [0002] Recently, with the rapid industrial development of semiconductors, electric and electronic technologies, and displays, synthetic resins or synthetic fibers are increasingly used in these fields, but a problem of static electricity occurs during processing. [0003] Generally, in the field of release films for protecting adhesive layers, antistatic properties have been required. Conventionally, an antistatic property has been provided to an adhesive layer to solve problems such as conta...
