Method of using pressure sensitive adhesive double coated sheet

A method of using a pressure sensitive adhesive double coated sheet, comprising:

• sticking a work piece to be processed to an energy radiation curable pressure sensitive adhesive layer of a pressure sensitive adhesive double coated sheet comprising a shrink substrate having a multiplicity of minute cuts and, superimposed on both sides thereof, pressure sensitive adhesive layers, at least one of the pressure sensitive adhesive layers being composed of an energy radiation curable pressure sensitive adhesive while sticking the other pressure sensitive adhesive layer to a hard plate having a hardness of at least 70 MPa defined by ASTM D883 so that the work piece is held on the hard plate;
• processing the work piece;
• irradiating the energy radiation curable pressure sensitive adhesive layer with energy radiation to cure the same and simultaneously shrinking the shrink substrate;
• and
• peeling the processed work piece from the energy radiation curable pressure sensitive adhesive layer having been irradiated and cured.
