Embodiment 1

[0111] 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 100 parts by weight of 2-ethylhexyl acrylate, 0.9 parts by weight of 8-hydroxyoctyl acrylate, 0.5 parts by weight of acrylic acid, 3 parts by weight of polyethylene glycol monoacrylate, 5 N-vinylpyrrolidone in parts by weight, and simultaneously add 60 parts by weight of solvent (ethyl acetate). 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 acrylic acid used in Example 1 with a weight average molecular weight of 500,000. Copolymer Solution 1. A part of the acrylic copolymer was taken and used as a sample for acid value measurement described later.

Embodiment 2～9 and comparative example 1～4

[0113] Except that the composition of each monomer was adjusted as described in (A) to (E) and (I-2) in Table 1, it was carried out in the same manner as the above-mentioned acrylic copolymer solution 1 used in Example 1, Acrylic copolymer solutions used in Examples 2-9 and Comparative Examples 1-4 were obtained.

[0115]

[0116]

[0117] [Example 1]

[0118] To the acrylic copolymer solution 1 of Example 1 manufactured as described above, 1.5 parts by weight of 1-octylpyridinium hexafluorophosphate, 0.2 parts by weight of KF-351A (polyether-modified siloxane of HLB=12) were added. Compound), 2.5 parts by weight of acetylacetone and stirring, add 1.0 parts by weight of Coronate HX (coronet HX, isocyanurate of hexamethylene diisocyanate compound), 0.2 parts by weight of Coronate L (coronet L, toluene diisocyanate compound and trimethylolpropane), 0.02 parts by weight of dioctyltin dilaurate, and then stirred and mixed to obtain the adhesive composition ...

Abstract

The invention provides an adhesive composition with excellent anti-static function, durability and machinability, and the balance of bonding force of the composition under low peeling speed and high peeling speed is excellent. The adhesive composition is formed by crylic acid polymer containing co-polymer; the co-polymer crylic acid polymer comprises (A) (methyl) acrylate monomer containing alkyl and having carbon number C4-C10, (B) co-polymer monomer containing hydroxyl, (C) co-polymer monomer containing carboxylic, (D) poly alkylene diol single (methyl) acrylate monomer and (E) vinyl monomer containing nitrogen without hydroxyl or (methyl) crylic acid alkyl ester monomer having alkoxy, (F) isocyanate compound having tri-sense, (G) cross-linking inhibitor, (H) cross-linking catalyst, (I) antistatic agent, and (J) polyether modified siloxane compound; and the acid value of the crylic acid polymer is 0.01-8.0.

Description

technical field [0001] The present invention relates to a surface protection film used in the manufacturing process of a liquid crystal display. More specifically, the present invention relates to an adhesive for a surface protection film for protecting the surface of an optical component such as a polarizing plate or a retardation plate by sticking on the surface of an optical component such as a polarizing plate or a retardation plate constituting a liquid crystal display. An adhesive composition, and a surface protection film using the adhesive composition. Background technique [0002] Conventionally, in the manufacturing process of optical components such as polarizing plates and retardation plates, which are components of liquid crystal displays, a surface protection film is attached to temporarily protect the surface of the optical component. Such a surface protection film is used only in the process of manufacturing an optical component, and when the optical compone...
