Embodiment 1

[0157] Nitrogen gas was introduced into a reaction apparatus equipped with a stirrer, a thermometer, a reflux condenser, and a nitrogen introduction pipe, thereby replacing the air in the reaction apparatus with nitrogen. Then, 100 parts by weight of 2-ethylhexyl acrylate, 5.0 parts by weight of 8-hydroxyoctyl acrylate, and 60 parts by weight of a solvent (ethyl acetate) were added to the reaction device. Then, 0.1 part by weight of azobisisobutyronitrile as a polymerization initiator was dropped over 2 hours, and reacted at a temperature of 65°C for 6 hours to obtain the acrylic copolymer solution of Example 1 with a weight average molecular weight of 500,000. To this acrylic copolymer solution, 8.5 parts by weight of acetylacetone was added and stirred, then 2.0 parts by weight of Coronate HX (isocyanurate of a hexamethylene diisocyanate compound), 0.1 parts by weight of titanium triacetylacetonate were added and Stirring and mixing were carried out to obtain the binder comp...

Embodiment 2～6 and comparative example 1～3

[0159] Except that each composition of the adhesive composition of Example 1 was adjusted as described in Table 1 and Table 2, the same operation was carried out as in Example 1, and the adhesives of Examples 2-6 and Comparative Examples 1-3 were obtained. binder composition. In Table 1 and Table 2, the monomers contained (copolymerized) in the acrylic copolymer are (A), (B), (C), (G) and "carboxyl group-containing monomer".

Abstract

To provide an antistatic surface protective film causing little contamination on an adherend and having an excellent antistatic performance on peeling while preventing degradation with time. The antistatic surface protective film is produced successively through steps of: forming a pressure-sensitive adhesive layer 2 made of a pressure-sensitive adhesive composition comprising an acrylic polymer as a copolymer and containing (F) an isocyanate compound having two or more functional groups, (G) a crosslinking accelerator, and (H) a ketoenol tautomer, on one surface of a base film 1 made of a resin having transparency; and bonding a release film 5 including a release agent layer 4 containing an antistatic on one surface of a resin film 3 to the surface of the pressure-sensitive adhesive layer 2 via the release agent layer 4. The release agent layer 4 is formed from a resin composition comprising a release agent essentially comprising dimethyl polysiloxane, a silicone compound that is liquid at 20 DEG C, and the antistatic. The pressure-sensitive adhesive layer 2 shows an electrification voltage on peeling within +-0.6 kV.

Description

technical field [0001] The invention relates to an adhesive composition and a surface protection film. Specifically, it relates to an antistatic surface protection film having antistatic properties. More specifically, the present invention provides a method for producing an antistatic surface protection film that is less polluting to an adherend, does not deteriorate over time, and has excellent anti-peeling static performance, and an antistatic surface protection film. Background technique [0002] At present, when manufacturing and transporting optical films such as polarizing plates, retardation plates, lens films for displays, anti-reflection films, hard coat films, transparent conductive films for touch panels, and optical products such as displays using them, A surface protective film is bonded to the surface of the optical film to prevent surface contamination and scratches in subsequent steps. In order to improve work efficiency by saving the labor and time of peel...
