Pressure sensitive adhesive sheet and method of use thereof

摘要

The invention is concerned with a pressure sensitive adhesive sheet comprising a substrate and, superimposed thereon, a pressure sensitive adhesive layer, said substrate exhibiting a maximum value of dynamic viscoelasticity tan delta of at least 0.5 at a temperature ranging from -5 to 80 DEG C. At the time of working of the back of an adherend having a surface whose irregularity height differences are large, this pressure sensitive adhesive sheet is preferably stuck to the adherend surface to thereby protect it during the working.
