<p>A pressure sensitive adhesive sheet which has a moderate adhesive strength, does hardly add physical stimuli to the adherend at the time of peeling and also has such a good processing suitability that the support does not generate swelling deformation by transfer of a liquid component from the adhesive layer. The pressure sensitive adhesive sheet has an adhesive layer formed from a resin composition comprising an acrylic acid ester polymer, a carboxylic acid ester having 16 or more carbon atoms which is compatible with the acrylic acid ester polymer and is liquid or paste at ordinary temperature, and a crosslinking component, and a film supporting the adhesive layer, comprising a polyether urethane resin obtained by allowing a polyol component to react with a polyisocyanate component, wherein the polyol component constituting the urethane resin contains at least one kind of polyether polyol having a polyoxyalkylene backbone represented by a specified repeating unit.</p> |
