摘要 |
<p>The present invention relates to an acrylic pressure sensitive adhesive composition comprising acrylic copolymers including alkyl(meth)acrylic acid ester monomer having 2~14 carbon atoms of alkyl group, characterized in that the gel fraction represented by the formula (1) is 45 ~ 75% , the swelling ratio represented by the formula (2) is 5 ~ 20, and the weight average molecular weight of sol eluted from the adhesive by ethyl acetate is at least 300,000. The acrylic pressure sensitive adhesive composition of the present invention has excellent balance of low rate peeling strength and high rate peeling strength, satisfactory wettability, and good polarizer surface protection and repeeling property.</p> |
