Problems solved by technology

[0005] In addition, in recent years, when peeling the surface protective film from optical members such as polarizers and retardation plates, it is considered that the peeling static electricity generated when peeling the adhesive layer from the adherend may affect the liquid crystal display. The failure of the electrical control circuit affects the

Embodiment 1

[0094]Nitrogen gas was introduced into a reaction device equipped with a stirrer, a thermometer, a reflux cooler, and a nitrogen gas introduction pipe, and the air in the reaction device was replaced with nitrogen gas. Then, add 12 parts by weight of methyl acrylate, 88 parts by weight of 2-ethylhexyl acrylate, 12.0 parts by weight of 8-hydroxyoctyl acrylate, 0.1 parts by weight of acrylic acid, 20 parts by weight of Polypropylene glycol monoacrylate (the average number of repeating units of alkylene oxide n=12) was added with 100 parts by weight of solvent (ethyl acetate). Then, 0.1 weight part of azobisisobutyronitrile was added dropwise as a polymerization initiator over 2 hours, and it was made to react at 65 degreeC for 8 hours, and the acrylic polymer solution of Example 1 was obtained.

Embodiment 2～6 and comparative example 1～3

[0096] In the same manner as the acrylic polymer solution used in the above-mentioned Example 1, except that the composition of the monomers was set as described in Table 1, the acrylic polymer solutions used in Examples 2-6 and Comparative Examples 1-3 were obtained. acrylic polymer solution.

[0097]

[0098] [Example 1]

[0099] In the acrylic polymer solution of Example 1 prepared as described above, add 2.0 parts by weight of crosslinking agent (CORONATE HX), 1.0 parts by weight of antistatic agent (lithium nonafluorobutanesulfonate), 0.1 parts by weight Parts of crosslinking accelerator (titanium triacetylacetonate) and 9 parts by weight of keto-enol tautomer compound (acetylacetone) were stirred and mixed to obtain the adhesive composition of Example 1. The adhesive composition was coated on a release film formed of a silicone resin-coated polyethylene terephthalate (PET) film, and then dried at 90° C. to remove the solvent, An adhesive layer with a thickness of 20 ...

Abstract

The present invention provides an adhesive composition and a surface protection film capable of achieving both excellent antistatic performance and stain resistance. The adhesive composition contains an acrylic polymer, an antistatic agent and a cross-linking agent, the acrylic polymer has a glass transition temperature below 0°C, the cross-linking agent is an isocyanate compound with more than three functions, and the The antistatic agent is an ionic compound formed by a cation and an anion with a melting point above 25°C, and the anion is selected from trifluoromethanesulfonate anion, pentafluoroethanesulfonate anion, heptafluoropropanesulfonate anion, nonafluorobutanesulfonate One of the group consisting of acid anions contains the antistatic agent as an essential component in a ratio of 0.01 to 10 parts by weight relative to 100 parts by weight of the acrylic polymer.

Description

technical field [0001] The invention relates to an adhesive composition containing an antistatic agent and a surface protection film. In more detail, it is an adhesive composition containing an ionic compound as an antistatic agent, which has excellent antistatic performance and stain resistance, and a surface protection film using the adhesive composition. The ionic compound has nine Specific sulfonate anions such as fluorobutanesulfonate. Background technique [0002] In the past, in the manufacturing process and assembly process of precision components and components such as electronic equipment components, optical equipment components, and image display panels, in order to temporarily protect the surfaces of these precision components and components, to prevent particles from the working environment atmosphere And the adhesion of gaseous pollutants, or the generation of scratches and dents, a surface protective film is attached to the surface of precision parts and comp...
