ADHESIVE SHEET AND ITS UTILIZING METHOD

摘要

PURPOSE: The adhesive sheet is provided which protects the surface by adhering in the processing of the other side of a material having a large difference of unevenness. CONSTITUTION: The adhesive sheet contains maximum value more than 0.5 of viscoelasticity. Thus, 50 parts by weight of urethane acrylate oligomer having average molecular weights of 5,000, 50 parts by weight of isobornyl acrylate, 2.0 parts by weight of photopolymerization initiator and 0.2 part by weight of phthalocyanine pigment are blended to give a photocurable resin composition. The obtained resin composition is coated to a thickness of 110 micrometer on the polyethylene terephthalate film, and cross-linked to give the adhesive sheet.
