Abstract: The invention relates to an acrylic adhesive composition, more particularly, to an adhesive composition which: specifies the contents of a (meth)acrylic ester-based monomer and an aromatic group-containing monomer of an acrylic copolymer as a composition having little or no difference of birefringence; has excellent durability; and can reduce light leakage due to flexure by mixing a crosslinkable functional group-containing acrylic copolymer (A) and an acrylic copolymer (B) which does not contain the crosslinkable functional group, in a ratio of 1:9 to 5:5.

Abstract: The present invention relates to a pressure-sensitive adhesive composition, a protective film for polarizers, which includes a cured product of the pressure-sensitive adhesive composition, a polarizer, and a liquid crystal display (LCD). In the present invention, a pressure-sensitive adhesive showing excellent endurance reliability in high-temperature and/or high-humidity conditions and having superior physical properties such as cuttability, re-peeling property, and workability can be provided. In particular, it is possible to provide the pressure-sensitive adhesive composition which can prevent light leakage that may occur in an LCD, even when being applied to a film having a low stress optical coefficient.
