Provided are a pressure-sensitive adhesive composition for a touch panel, a conductive film, a touch panel and a pressure-sensitive adhesive film. The exemplary pressure-sensitive adhesive composition for a touch panel, the conductive film or the pressure-sensitive adhesive film has excellent durability and optical properties such as transparency. In addition, such physical properties are stably maintained under severe conditions. Particularly, a pressure-sensitive adhesive layer is attached to a conductor thin film, and thus resistance change of the conductor thin film is effectively inhibited even when the conductor thin film is exposed to the severe conditions. Therefore, the pressure-sensitive adhesive composition may be effectively used to manufacture a touch panel.

摘要:
Provided is a substrate for processing a wafer. The present invention can provide a substrate having excellent heat resistance and dimensional stability. The present invention can provide a substrate that has excellent stress relaxation properties, and therefore can prevent a wafer from being destroyed due to residual stress. Also, the present invention can provide a substrate that can prevent a wafer from being damaged or fried off due to a non-uniformly applied pressure during the wafer processing process, and that exhibits excellent cuttability. For these reasons, the substrate can be useful as a sheet for processing a wafer in various wafer preparation processes such as dicing, back-grinding, and picking-up.
