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/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.

摘要： A pressure-sensitive adhesive (PSA) sheet with low sulfur gas emission is provided. Metal corrosion due to outgassing components of the adhesive sheet is thereby prevented. The sheet comprises a PSA layer formed from a water-dispersed PSA composition. The PSA composition contains a water-dispersed acrylic polymer synthesized using a sulfur-containing chain transfer agent. Moreover, in a gas generation test whereby the PSA sheet is heated at 85°C for one hour, the emission of sulfur-containing gas is 0.043 ¼g or less per 1 cm 2 surface area of the sheet, when converted to SO 4 2- .
