Acrylic pressure-sensitive adhesive composition for polarizing film
First Claim
1. An acrylic pressure-sensitive adhesive composition for a polarizing film comprising a) 100 parts by weight of an acrylic copolymer prepared from copolymerization of i) 35-94.9 parts by weight of a (meth)acrylic ester monomer for preparing a homopolymer having a glass transition temperature ranging from −
- 45°
C. to 10°
C.;
ii) 5-50 parts by weight of a (meth)acrylic ester monomer for preparing a homopolymer having a glass transition temperature ranging from −
90°
C. to −
50°
C.; and
iii) 0.1-15 parts by weight of a vinylic monomer, an acrylic monomer or a mixture thereof having a functional group that can be crosslinked; and
b) 0.01-10 parts by weight of a multifunctional crosslinking agent.

Abstract
Provided is an acrylic pressure-sensitive adhesive composition for a polarizing film comprising an acrylic copolymer copolymerized from (meth)acrylic ester monomers having different glass transition temperatures. The acrylic pressure-sensitive adhesive composition of the present invention can minimize the problem of light leakage due to shrinkage or expansion of a polarizing film attached to a liquid crystal display panel because it has very superior stress relaxation ability while maintaining superior major properties such as adhesion durability, cuttability, etc.
