摘要 |
<p>A removable pressure sensitive adhesive composition includes at least (A) a hydroxyl-group-containing acrylic polymer, (B) an amine compound containing plural hydroxyl groups, and (C) a polyisocyanate compound and has a gel fraction of equal to or more than 70% by weight after drying or curing. A removable pressure sensitive adhesive sheet has a removable pressure sensitive adhesive layer including the removable pressure sensitive adhesive composition formed on one or both sides of a base material. The sheet may have a 180 DEG peel force with respect to a melamine-faced steel sheet of 5 N/20-mm or less and may have a 180 DEG peel force after adhesion at 50 DEG C for 48 hours of 1.2 times or less the initial adhesion (after adhesion at 23 DEG C for 20 minutes), as determined at a pulling rate of 300 mm/minute, 23 DEG C and 50% relative humidity.</p> |
