<p><P>PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive sheet obtained using a water-dispersed pressure-sensitive acrylic adhesive composition, in which properties of corroding a metal in a noncontact state are controlled. <P>SOLUTION: The pressure-sensitive adhesive sheet includes a pressure-sensitive adhesive layer formed from a water-dispersed pressure-sensitive adhesive composition containing a water-dispersed acrylic polymer synthesized using a chain transfer agent not having sulfur as a constituent atom. The pressure-sensitive adhesive sheet diffuses≤0.043μg/1 cm<SP>2</SP>of sulfur-containing gases (in terms of SO<SB>4</SB><SP>2-</SP>) upon heating at 85°C for 1 h, has adhesive force to an ABS plate of≥10 N/20 mm, and shows a retention time of≥1 h in an 80°C retention test. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
