US 2012/0231245 A1 · ADHESIVE FILM AND TOUCH PANEL

Abstract

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.
