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

[0104] Nitrogen gas was introduced into the reaction apparatus equipped with a stirrer, a thermometer, a reflux condenser, and a nitrogen gas introduction pipe, and the air in the reaction apparatus was replaced with nitrogen gas. Then, 100 parts by weight of 2-ethylhexyl acrylate, 6.0 parts by weight of 8-hydroxyoctyl acrylate, 0.1 part by weight of acrylic acid, and a solvent (ethyl acetate) were simultaneously added to the reaction apparatus. Then, 0.1 part by weight of azobisisobutyronitrile as a polymerization initiator was added dropwise over 2 hours, and the reaction was carried out at 65° C. for 6 hours to obtain the acrylic polymer used in Example 1.

Embodiment 2～6 and comparative example 1～3

[0106] Except that the composition of the monomers was adjusted to the descriptions in (A), (B-1), and (B-2) of Table 1, respectively, in the same manner as the above-mentioned acrylic polymer solution used in Example 1, Acrylic polymer solutions used in Examples 2 to 6 and Comparative Examples 1 to 3 were obtained.

[0107]

[0108] [Example 1]

[0109] 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) were added methanesulfonate), 0.1 parts by weight of a cross-linking catalyst (titanium triacetylacetonate) and 8.5 parts by weight of acetylacetone were stirred and mixed to obtain the adhesive composition of Example 1. After apply|coating this adhesive composition on a mold release film (PET film coated with a silicone resin), the solvent was removed by drying at 90 degreeC, and the adhesive layer with a thickn...

Abstract

The present invention provides an excellent adhesive performance such as a bonding performance that can be balanced at low -speed peeling speed and high -speed peeling speed. At the same timeThe adhesive film and surface protective film of the adhesive composition.In the composition of the adhesive, (F) the antistatic agent is a general K + · A ‑ The melting point shown is a ionic compound of 25-80 ° C. Among them, K + In order to choose a group composed of groups of free pyridine, pyrimazole, pyrodis, pyrine, pyrodermine, ammonium, ammonia, albumin, pyrine, pyrazole, nail carbon positive ion, morpholine ion, and morpholine ionOne of the cations, A ‑ In order to choose a group of anion in a group composed of a group composed of ionic ions composed of a toto fluorine, sulfons, and pentraromythane sulfonate, compared to the 1001 to 10 weights compared to the 1001 to 10 portion compared to 100 weights of acrylic polymersThe proportion contains ionic compounds.

Description

technical field [0001] The present invention relates to an antistatic agent-containing adhesive composition, and an adhesive film and surface protection film using the same. More specifically, it relates to providing an adhesive composition capable of achieving a low peeling speed and a high peeling speed, and an adhesive film and a surface protective film using the same. It has excellent adhesion properties such as balanced adhesion, and at the same time, it can achieve both antistatic properties and anti-pollution properties. 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 together. Such a surface protection film is used only in the process of manufacturing an optical member, and when attaching an optical member to a liquid crystal display,...
