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 method is provided for producing a double-sided pressure-sensitive adhesive (PSA) sheet of a nonwoven fabric substrate, whereby the inherent performance of the PSA is more fully exploited using an aqueous dispersion-type PSA composition. This method comprises preparing an aqueous dispersion-type PSA composition and a nonwoven fabric substrate serving as a support. The method also comprises forming PSA layers which impregnate the substrate and which are obtained by drying the composition. These PSA layers impregnate the substrate so that the area of gaps observed in a vertical cross-section perpendicular to the machine direction of the substrate is about 500 µm 2 /400 µm or less.
