    摘要： A pressure-sensitive adhesive sheet has a high adhesiveness and an excellent terminal peeling resistance as well as exhibits extremely small diffusing amounts of formaldehyde and toluene. The pressure-sensitive adhesive sheet contains at least a pressure-sensitive adhesive layer of a water-dispersion type acrylic pressure-sensitive adhesive containing a water-dispersion type acrylic polymer and a tackifying resin-containing emulsion, wherein a diffusing amount of formaldehyde is less than 3 μg/m3 and a diffusing amount of toluene is 10 μg/g or less. As the tackifying resin-containing emulsion, a tackifying resin-containing emulsion prepared using substantially no organic solvents or a tackifying resin-containing emulsion prepared using a material other than aromatic hydrocarbon-based organic solvents can be suitably employed.

    摘要： Provided is a PSA sheet with low toluene and total volatile organic compound (TVOC) emissions as well as low unpleasant odor level felt by users. The PSA sheet comprises a PSA layer formed of a PSA composition comprising an acrylic polymer emulsion and a tackifier resin emulsion; the toluene and TVOC emissions are at most 20 μg and at most 150 μg, respectively; in a sensory test, 90% of participants evaluate that the unpleasantness of odors emitted from the PSA sheet is less than that of toluene at a prescribed concentration.
