The present invention relates to an adhesive film and to a touch panel. According to the present invention, even when the adhesive film is applied to a touch panel, for example, a capacitive touch panel, and directly attached to a conductive layer, the adhesive film effectively prevents the resistance of the conductive layer from being raised and exhibits good heat resistance. In addition, according to the present invention, an adhesive film having superior durability, optical characteristics, cuttability, workability, wettability and resistance to warping is provided.

The present invention relates to an acrylic pressure sensitive adhesive composition comprising a monomer containing linear carbonate having an antistatic property. The acrylic pressure sensitive adhesive composition exhibits an excellent balance between low-rate peel strength and high-rate peel strength, and is capable of lowering the content of an antistatic agent. It also provides excellent releasable property, and protection of the surface of a polarizer due to proper wettability.
