Embodiment 1

[0148] 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, added 2-ethylhexyl acrylate of 100 parts by weight, 8-hydroxyoctyl acrylate of 4.5 parts by weight, polypropylene glycol monoacrylate (Polypropylene glycol monoacrylate) (n=12) of 10 parts by weight in the reaction device , and simultaneously added 60 parts by weight of solvent (ethyl acetate). 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 2.5 parts by weight of Coronate HX (isocyanurate of hexamethylene diisocyanate compound), 0.1 part by wei...

Embodiment 2～6 and comparative example 1～3

[0150] 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), (F) and "carboxyl group-containing monomer".

Abstract

The present invention provides an antistatic surface-protective film that has little contamination of an adherend and that has excellent peeling antistatic performance which does not deteriorate over time. In accordance with the present invention, on one surface of a base film 1 including a transparent resin, is formed an adhesive layer 2 including an adhesive composition, which includes an acrylic-based polymer of a copolymer including (A) a least one (meth)acrylic acid ester monomer having a C4 to C18 alkyl group and (B) at least one hydroxyl group-containing copolymerizable monomer, but not including a carboxyl group-containing copolymerizable monomer, and which further contains (C) a bifunctional or higher isocyanate compound, (D) a cross-linking promoting agent, and (E) a keto-enol tautomer compound; and a peeling film 5, which has a release agent layer 4 laminated, is attached on a surface thereof, wherein the release agent layer 4 includes a release agent having dimethylpolysiloxane as the main component and an antistatic agent.

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 production of an antistatic surface protection film that has less contamination to an adherend, does not deteriorate over time (does not deteriorate over time), and has excellent anti-peeling static performance. method, 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 efficie...
