<p>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 using a solvent that does not contain an aromatic hydrocarbon-based 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.</p> |
