摘要： 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.
摘要翻译：压敏粘合剂组合物，保护膜，光学元件和显示装置本发明涉及压敏粘合剂组合物，保护膜，光学元件和显示装置。使用根据本发明的压敏粘合剂组合物形成的压敏粘合片可以具有适当的高速和低速剥离强度，并且同时可以表现出高速剥离强度和低速剥离强度之间的优异平衡。使用根据本发明的一个示例性实施方式的压敏粘合剂组合物形成的压敏粘合片显示出适当水平的表面电阻和优异的静电放电特性，并且即使当压敏粘合剂组合物没有被污染时，在将粘合片长期粘贴于被粘物之后，将粘合片从被粘物上剥离。使用根据本发明的一个示例性实施方式的压敏粘合剂组合物形成的这种压敏粘合片可以应用于各种应用领域。例如，该压敏粘合剂片可以用作用于诸如偏光板的光学部件的保护膜。
