Abstract
Provided herein is an improved self-adhesive sheet composed of a base member having a water-soluble polymer layer on its reverse side and a release member, with a pressure sensitive adhesive layer interposed between them, in which the bond strength between the water-soluble polymer layer and the pressure sensitive adhesive layer remains high. It can be stuck readily without moistening; and yet it can be peeled off easily simply by dipping in water.
