Embodiment 1

[0127] 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, 8-hydroxyoctyl acrylate of 3.0 parts by weight, acrylic acid of 0.4 parts by weight, polypropylene glycol monoacrylate of 10 parts by weight The average repeating number of alkylene oxides of the alkyl diol chain n=12), and 60 parts by weight of solvent (ethyl acetate) was added at the same time. 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 used as a sample for acid value measurement described later.

Embodiment 2～6 and comparative example 1～7

[0129] 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 to 6 and Comparative Examples 1 to 7 were obtained.

[0133] [Example 1]

[0134] To the acrylic copolymer solution 1 of Example 1 manufactured as described above, 1.5 parts by weight of 1-octylpyridinium hexafluorophosphate, 0.05 parts by weight of polyether-modified siloxane compound (HLB=7), 8.5 parts by weight were added. After stirring acetylacetone and 0.1 part by weight of α-tocopherol, 2.0 parts by weight of Coronate HX (Coronate HX, isocyanurate of hexamethylene diisocyanate compound) and 0.1 part by weight of titanium triacetylacetonate were added. Stir and mix to obtain the binder composition of Example 1. This adhesive composition was coated on a release film...

Abstract

The present invention provides an adhesive composition which possesses an anti-static performance, is excellent in binding force balance at low peel-away speed and high peel-away speed, is long in storage period, and is also excellent in durability and reprocessability. The adhesive composition of the present invention comprises (A) a (meth) acrylate monomer of which the carbon number of alkyl is C4-C18, (B) a copolymerizable monomer having hydroxide radical, (C) a copolymerizable monomer having carboxyl, (D) a poly alkylene glycol single (meth) acrylate monomer, (E) a vinyl monomer having nitrogen instead of hydroxy or alkyl(meth)acrylates having alkoxy, acrylic copolymer of copolymer of which the acid value is 0.01-8.0, (F) a bifunctional isocyanate compound, (G) a crosslinking catalyst of a metallo-chelate, (H) a ketone-enol tautomer compound, (I) an antistatic agent, (J) a polyether modified silicone compound, and (K) an antioxidant.

Description

technical field [0001] The invention relates to an adhesive composition and a surface protection film. In more detail, the present invention relates to the provision of a polarizing plate having antistatic properties, excellent balance of adhesive force at low peeling speed and high peeling speed, long shelf life, durability, and reworkability. Adhesive composition for surface protection film and surface protection film. Background technique [0002] For adhesives for optical applications, from the viewpoint of excellent transparency, it is preferable to use an alkyl (meth)acrylate copolymerized with an acrylic monomer having a hydroxyl group, a carboxyl group, etc. as a functional group. Acrylic adhesive composed of In addition, adhesives that appropriately adjust various physical properties such as adhesive force are required. In particular, in order to be suitable for the manufacturing process of factory production, adhesives for surface protection films, etc., require...
