发明名称 PRESS BONDING TYPE, PRESSURE-SENSITIVE ADHESIVE DOUBLE COATED SHEET
摘要 PROBLEM TO BE SOLVED: To provide a press bonding type, pressure-sensitive adhesive double coated sheet which is excellent in removability for repositioning for application and, when exposed to winding pressure and the like at the time of winding into a roll, is less likely to lose the removability. SOLUTION: This press bonding type, pressure-sensitive adhesive double coated sheet comprises: an acrylic pressure-sensitive adhesive sheet comprising an acrylic polymer prepd. by applying an actinic radiation to a photopolymerizable compsn. composed mainly of an alkyl (meth)acrylate, the acrylic pressure-sensitive adhesive sheet having a compression modulus of elasticity at 25% compression of 0.1 to 50kg/cm<2> ; and a 10 to 100μm-thick non- pressure-sensitive adhesive or slightly pressure-sensitive adhesive masking member laminated on at least one surface of the acrylic pressure-sensitive adhesive sheet so that the surface of the masking member is protruded on the surface of the acrylic pressure-sensitive adhesive sheet and the masking member covers 12 to 50% of the surface of the acrylic pressure-sensitive adhesive sheet.
