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.
