摘要 |
<p>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/m 3 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.</p> |
