Abstract

The present invention relates to an acrylic pressure sensitive adhesive composition comprising (meth)aciylic 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.
