摘要： The present invention provides a pressure-sensitive adhesive (PSA) sheet provided with a non-toluene-based PSA layer and having superior adhesion properties. A PSA sheet 8 is provided with a release liner 87 having, on at least a first side thereof, a release layer composed of a silicone-based release agent, and a PSA layer 85 provided on the release layer. A PSA composition that composes the PSA layer 85 contains a water-dispersed acrylic polymer and a tackifier resin emulsion prepared without using an organic solvent. The release layer has an amount of silicone that transfers to Single-Sided Adhesive Tape No. 31B manufactured by Nitto Denko Corporation of 10 kcps or less per unit surface area equivalent to a circle having a diameter of 30 mm when determined as X-ray intensity of silicon by X-ray fluorescence analysis.

摘要： The present invention provides a double-sided pressure-sensitive adhesive sheet using a plastic film substrate, ensuring good laminating workability and no elongation or rupture at the lamination even when used in a narrow or long form, where the double-sided pressure-sensitive adhesive sheet has excellent adhesive property and at the same time, exerts excellent peelability (releasability) without causing an adhesive residue at the separation. The present invention relates to a double-sided pressure-sensitive adhesive sheet comprising a plastic film substrate; and a pressure-sensitive adhesive layer on both sides of the plastic film substrate, wherein a 180° peeling pressure-sensitive adhesive force of a surface (surface A) of one of the pressure-sensitive adhesive layer to a stainless steel plate as measured at a tensile speed of 300 mm/min is 8 N/20 mm or more, and an adhesive residue is not generated in the releasability evaluation test.
