<p><P>PROBLEM TO BE SOLVED: To provide a double-sided pressure-sensitive adhesive (PSA) sheet that is provided with both adhesion performance and removability that enables the PSA sheet to be preferably used for scheduled recyclable parts. <P>SOLUTION: The double-sided pressure-sensitive adhesive sheet 1 is provided with a substrate 10, PSA layers 21 and 22 each applied to each side of the substrate 10, and a release liner 31 laminated onto at least the PSA layer 21. The PSA layer 21 contains a PSA component synthesized in an organic solvent. The liner 31 has a release layer comprised of a silicone release agent on at least the side contacting with the PSA layer 21. The substrate 10 is comprised of a non-woven fabric having a basis weight of 10-25 g/m<SP>2</SP>, tensile strength in both lengthwise and widthwise directions of 9-20 N/10 mm, and a grain ratio of 70-140%. The amount of silicone transfer of the release layer measured by a predetermined method is 10 kcps or less per area equivalent to a circle of 30 mm diameter. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
