Embodiment 1

[0074] [embodiment 1] the preparation of acrylic acid copolymer

[0075] A monomer mixture consisting of 98.3 parts by weight of n-butyl acrylate (BA), 0.5 parts by weight of acrylic acid (AA) and 1.2 parts by weight of hydroxyethyl methacrylate (2-HEMA) was added to a 1L Nitrogen was refluxed and the temperature was adjusted in the reactor of the cooling system, and then 100 parts by weight of ethyl acetate (EAc) was added as a solvent. Oxygen was purged by purging with nitrogen for 1 hour while the temperature was maintained at 62°C. After homogenization, 0.03 parts by weight of azobisisobutyronitrile (AIBN), a polymerization initiator diluted to 50% with ethyl acetate, was added. The mixture was reacted for 8 hours to produce an acrylic acid copolymer.

[0076] mixing process

[0077] To 100 parts by weight of the acrylic copolymer prepared above, add 0.5 parts by weight of the toluene diisocyanate adduct of the crosslinking agent trimethylolpropane (TDI-1), 5 parts by w...

Embodiment 2～4

[0081] As shown in Table 1, based on the ingredients of Example 1, the contents of some ingredients were adjusted up or down to carry out the copolymerization reaction. The preparation, mixing and lamination of the acrylic copolymer was carried out in the same manner as described in Example 1 except that the mixing process was adjusted up or down. The durability and surface resistance were also detected by the same method as described in Example 1, and the results are shown in Table 2.

Abstract

The present invention relates to an acrylic pressure sensitive adhesive composition for the production of a polarizer, which has excellency in major characteristics including durability and antistatic property, more precisely, an acrylic pressure sensitive adhesive composition containing ester plasticizer having one or more ether bonds and alkali metallic salt, a polarizer applied with the pressure sensitive adhesive and liquid crystal display (LCD) device using the same. The acrylic pressure sensitive adhesive composition for the production of a polarizer of the present invention has excellent pressure sensitive adhesive functions and durability.

Description

technical field [0001] The present invention relates to an acrylic pressure-sensitive adhesive composition having antistatic properties, and more particularly, to an acrylic pressure-sensitive adhesive resin composition having excellent durability and antistatic properties. Background technique [0002] The acrylic pressure-sensitive adhesive composition has been widely used in the industry to produce industrial sheets, optical pressure-sensitive adhesive products, and pressure-sensitive adhesives for electronic components, etc., and has been applied to other products having the same concept. industrial field. [0003] Due to its potential for weight reduction and thinning, liquid crystal display devices (LCDs) are replacing CRTs in many products in various high-tech fields such as notebook computers, monitors, and TVs. [0004] In general, liquid crystal elements and polarizers are the basic materials for producing LCDs, and in order to adhere the two, a suitable pressure-...
