Abstract

The present invention relates to a pressure-sensitive adhesive composition, a protective film, an optical element, and a display device. A pressure-sensitive adhesive sheet formed using the pressure-sensitive adhesive composition according to the present invention can have proper high-speed and low-speed peel strengths and simultaneously can exhibit an excellent balance between the high-speed and low-speed peel strengths. The pressure-sensitive adhesive sheet formed using the pressure-sensitive adhesive composition according to one exemplary embodiment of the present invention exhibits a proper level of surface resistance and excellent electrostatic discharge characteristics, and has no contaminants with respect to an adherend even when the pressure-sensitive adhesive sheet is peeled from the adherend after the pressure-sensitive adhesive sheet is attached to the adherend for a long period of time. Such a pressure-sensitive adhesive sheet formed using the pressure-sensitive adhesive composition according to one exemplary embodiment of the present invention can be applied to various fields of applications. For example, the pressure-sensitive adhesive sheet can be used as a protective film for optical members such as polarizing plates.
