Abstract
A low-staining adhesive sheet provided with an adhesive layer containing as the main component a pressure-sensitive adhesive polymer on a base film, wherein the pressure-sensitive adhesive polymer is substantially free from oligomeric low-molecular weight matters; and a method for removing a resist material by using this low-staining adhesive sheet. This low-staining adhesive sheet gives no organic staining matters remaining on the surface of article (for example, substrate) to be used as an adherend and is useful in removing a resist material and foreign matters, and re-peeling surface-protectors, masking materials, and other materials.
