摘要：
A double-sided pressure-sensitive adhesive (PSA) sheet 11 has, on each side of a plastic film substrate 1, a PSA layer 3 provided through an undercoat layer 2 containing a compound having an oxazoline group. The PSA layer 3 is formed from a water-dispersed PSA composition. This PSA composition contains an acrylic polymer synthesized by emulsion polymerization of a monomer raw material containing an alkyl(meth)acrylate and a carboxyl group-containing monomer, and a water-dispersed tackifier at a mass ratio of 100:5 to 100 based on solid content. The toluene emission when this PSA sheet is kept at 80°C for 30 minutes is 20 µg or less per gram of the sheet.
