  • Patent number: 7846542
    Abstract: There is provided a pressure-sensitive adhesive composition for optical films. The composition can form a pressure-sensitive adhesive layer that can prevent light leakage caused by stress associated with dimensional change of a component such as an optical film, which include the pressure-sensitive adhesive layer that has reworkability such that it can be easily peeled from a component, and that has satisfactory processability such that it can be processed without pressure-sensitive adhesive stain or dropout, after it is formed on an optical film. A pressure-sensitive adhesive optical film produced using the composition is also provided. The pressure-sensitive adhesive composition includes a (meth)acrylic polymer including (a) 34 to 94% by weight of an alkyl(meth)acrylate monomer unit, (b) 5 to 35% by weight of an aromatic ring-containing (meth)acrylate monomer unit, and (c) 0.01 to 0.5% by weight of an amino group-containing (meth)acrylate monomer unit and further including (d) 0.
