Abstract
Official abstract text for this publication.
The present invention relates to an acrylic pressure sensitive adhesive composition comprising (meth)acrylic copolymers including alkyl(meth)acrylic acid ester monomer having 1˜12 carbon atoms of alkyl group, characterized in that the gel content is 10˜55%, the swelling ratio is 30˜110, the weight average molecular weight of sol eluted from the adhesive by ethyl acetate is at least 800,000, the molecular weight distribution is 2.0˜7.0; and a polarizer and a liquid crystal display comprising the above composition show excellent durability under a high temperature and humidity condition, and can improve the light leakage phenomenon and provide excellent operability at the time of manufacturing polarizer by effectively providing high modulus and stress release property.
First claim
Opening claim text (preview).
What is claimed is: 1. An acrylic pressure sensitive adhesive composition for polarizing film comprising (meth)acrylic copolymers including alkyl(meth)acrylic acid ester monomer having 1 to 12 carbon atoms of alkyl group and a multifunctional crosslinking agent, wherein the meth(acrylic) copolymers comprise an acrylic polymer for crosslinking structure and an acrylic polymer for non-crosslinking structure, wherein the meth(acrylic) copolymers and the multifunctional crosslinking…
