Problems solved by technology

[0023] However, with regard to the antistatic adhesive composition described in Patent Document 5, although there is disclosed a technique for improving antistatic performance and bleeding, there is no description that the adhesive force at a low-speed peeling speed and a high-speed peeling speed can be obtained. Adhesive composition with excellent adhesive properties such as balance, but there remains a technical problem of obtaining an adhesive composition with excellent adhesive properties

Embodiment 1

[0105] Nitrogen gas was introduced into a reaction device equipped with a stirrer, a thermometer, a reflux condenser, and a nitrogen gas introduction tube to replace the air in the reaction device with nitrogen gas. Then, 100 parts by weight of 2-ethylhexyl acrylate, 6.0 parts by weight of 8-hydroxyoctyl acrylate, 0.1 parts by weight of acrylic acid, and a solvent (ethyl acetate) were simultaneously added to the reaction device. Then, 0.1 parts by weight of azobisisobutyronitrile as a polymerization initiator was dropped over 2 hours, and reacted at 65° C. for 6 hours to obtain an acrylic polymer used in Example 1.

Embodiment 2～6 and comparative example 1～3

[0107] In the same manner as the acrylic polymer solution used in Example 1, Acrylic polymer solutions used in Examples 2-6 and Comparative Examples 1-3 were obtained.

[0108]

[0109] [Example 1]

[0110] To the acrylic polymer solution of Example 1 prepared as described above, 2.5 parts by weight of a crosslinking agent (CORONATE HX), 1.5 parts by weight of an antistatic agent (1-octyl-2-methylpyridinium trifluoro methanesulfonate), 0.1 parts by weight of a crosslinking catalyst (titanium triacetylacetonate) and 8.5 parts by weight of acetylacetone were stirred and mixed to obtain the adhesive composition of Example 1. After coating this adhesive composition on a release film (a PET film coated with a silicone resin), the solvent was removed by drying at 90° C. to obtain an adhesive layer with a thickness of 20 μm. Then, the adhesive layer with the release film is transferred to the surface of the substrate film (PET film with antistatic and antifouling treatment on one...

Abstract

The invention provides an adhesive composition, an adhesive film using the adhesive composition, and a surface protective film using the adhesive composition. The adhesive composition has excellent adhesive performance such as balanced adhesive force at a low peeling speed and a high peeling speed, and can achieve both antistatic performance and anti-fouling performance. In the adhesive composition, the antistatic agent (F) is an ionic compound having a melting point of 25-80 DEG C and represented by general formula (1) K<+>.A<->, wherein K<+> is a cation, A<-> is one anion selected from the group consisting of imido group-free, trifluoromethane sulfonate ions, pentafluoroethane sulfonate ions; the acrylic polymer is an acrylic polymer having a glass transition temperature of 0 DEG C or less, and the acrylic polymer contains an ionic compound as an essential component in an amount of 0.01-10 parts by weight per 100 parts by weight of the acrylic polymer.

Description

technical field [0001] The present invention relates to an adhesive composition containing an antistatic agent, an adhesive film and a surface protection film using the adhesive composition. More specifically, it relates to providing an adhesive composition, an adhesive film and a surface protection film using the adhesive composition, and the adhesive composition can be obtained under low-speed peeling speed and high-speed peeling speed. Excellent adhesive performance such as balanced adhesion, and at the same time, it can seek to balance antistatic performance and anti-pollution performance. Background technique [0002] Conventionally, in the manufacturing process of optical members, such as a polarizing plate which is a member which comprises a liquid crystal display, in order to temporarily protect the surface of an optical member, a surface protection film is bonded. Such a surface protection film is used only in the process of manufacturing an optical member, and whe...
