Problems solved by technology

However, polarizing plates using these hydrophobic resins in protective films are more likely to be charged than conventional polarizing plates using cellulose triacetate films as protective films. Triboelectrification due to friction, etc., may cause display failure (so-called display unevenness and whitening phenomenon) due to disorder of liquid crystal alignment, which becomes a problem

[0151] [Preparation of Adhesive Composition (Solution)]

[0152] Prepared as above, prepared each compounding component was compounded at the ratio shown in the following Table 2 to prepare an adhesive composition, which was diluted with ethyl acetate to prepare an adhesive composition solution ( Solid content concentration 13%). In addition, in the following Table 2, each compounding quantity of an antistatic agent (B), a crosslinking agent (C), and a silane coupling agent (D) is the whole acrylic resin (A) being 100. The converted value is the part by weight.

[0155] Next, the adhesive composition solutions of Examples and Comparative Examples were applied to a polyester-based release sheet so that the thickness after drying was 25 μm, and after drying at 100° C. for 3 minutes, the formed adhesive was assembled. The material layer was transferred to a polarizing plate (protective film: TAC film manufactured by Fujifilm Co., Ltd.), and aged ...

Abstract

To provide an adhesive composition that does not bleed out even if the content of an antistatic agent is increased, does not adversely affect durability, can exhibit antistatic performance stably over a long period of time, and has excellent aging properties. For an adhesive composition containing an acrylic resin (A) and an antistatic agent (B), the acrylic resin (A) contains an amide group and a functional group other than the amide group, and is derived from The structural unit of the functional group monomer (a1) accounts for 1 to 10% by weight of the acrylic resin (A), the antistatic agent (B) includes an ammonium-based antistatic agent, and the content of the antistatic agent (B) is relative to that of the acrylic resin. 100 weight part of resins (A) are 1.2-15 weight part.

Description

technical field [0001] The present invention relates to an adhesive composition, an adhesive obtained by using the same, and an adhesive for polarizing plates. More specifically, it relates to: formation of antistatic properties, durability, and aging An adhesive composition having a well-balanced and excellent adhesive, an adhesive obtained using the same, and an adhesive for polarizing plates. Background technique [0002] A liquid crystal display panel is generally obtained by adhering a polarizing plate through an adhesive to the surface of a liquid crystal cell having an aligned liquid crystal component sandwiched between two glass plates. Conventionally, as such a polarizing plate, a polarizing plate having a three-layer structure in which a polarizer made of a polyvinyl alcohol-based resin is sandwiched between protective films made of a cellulose triacetate resin has been used. [0003] In recent years, as polarizing plates for liquid crystal display panels, acrylic...
