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： The present invention provides a double-sided adhesive tape which enables suppression of deterioration of pressure-sensitive adhesive characteristics due to foaming of the surface of a pressure-sensitive adhesive, and occurrence of poor appearance, and is less likely to generate wrinkles in the case of taking up the tape and does not cause interlaminar fracture (delamination) upon peeling even after practical use during which heat history is loaded for a long time, and also which is less likely to be torn off or to generate adhesive residue upon peeling off the double-sided adhesive tape from one side of the adherend, and is excellent in peeling property; and a method for producing the same. Particularly, the present invention provides a method for producing a double-sided adhesive tape, which causes neither generation of wrinkles nor cutting of a nonwoven fabric base material even when a pressure-sensitive adhesive is applied to the nonwoven fabric base material at a higher speed than in the case of the prior art, and also has improved productivity. Disclosed is a double-sided adhesive tape including a nonwoven fabric base material containing substantially no binder component and having a tensile strength in a longitudinal direction of from 4.1 to 10.0 N/10 mm; and a pressure-sensitive adhesive layer provided on both surfaces of the nonwoven fabric base material; wherein the double-sided adhesive tape has an initial tensile strength in the longitudinal direction of 17.0 N/10 mm or more.
